IV. A List of the Heteropterous and Homopterous Hemiptera of South-

West Africa.—By A. J Hesse, B.Sc., Ph.D., Assistant.

(With Plates I-VIIT.)

THE following is a list of the Hemiptera present in the South African

Museum collections and those described from the same region by

other authors. The list comprises all the families of the Heteroptera

and Homoptera, except the Jassidae, Aphidae, and Coccidae. The

insects were mostly collected by members of the staff on the Museum

Expeditions of 1916 (R. W. E. Tucker), 1918 (R. W. E. Tucker), 1919

(Lightfoot and J. Drury), 1921 (K. H. Barnard, J. Drury, and S. Gil-

man), and 1923 (K. H. Barnard and R. F. Lawrence). In addition,

there are specimens obtained from private collectors, such as J. S.

Brown, H. Kéchig, Dr. Knobel, Miss Wilman, and the well-known

traveller Eriksson.

The list includes geographically only those species found within

the boundaries of S.-W. Africa, comprising the three areas of Great

Namaqualand, Damaraland, and Ovamboland. In each instance

both the area and the locality are stated, and “S.A.M.” is printed

opposite those species of which the Museum possesses representatives,

and (M. Exp.) after the names of the localities where members of the

staff collected the species.

The figures are free-hand drawings by the author.

The Hemiptera of 8.-W. Africa have been sadly neglected i ento-

mologists in the past, and the only literature up to 1913 dealing with

descriptions of species from that region is ©. Stal’s “ Hemiptera

Africana,’ pts. 1-4, 1864-66, and the few descriptions of isolated

species by other authors in different works (alluded to in the list)

from material that found its way into European collections. A definite

survey of the order in this region was for the first time undertaken

in 1913 by F. Schumacher in a list, with descriptions of new species,

which was published in the “ Jenaische Denkschriften,”’ xvii, pp. 50-88,

as a result of Dr. L. Schultze’s “‘ Forschungsreise im West. und Zent.

Siidafrika, 1903-1905.”’

As a result of the Museum Expeditions up to 1924, we have been

able to enrich the knowledge of that region by the descriptions of

several new and interesting species. Altogether 11 new genera,

58 new species, and 2 new varieties are described in the following

families :—

Pentatomidae, 11 n. sp., 1 n. var.

Coreidae, 6 n. sp.

Lygaeidae, 2 n. gen., 8 n. sp.

Tingididae, 1 n. gen., 1 n. sp.

Reduvudae, 3 n. gen., 11 n. sp., and 1 n. var.

Cicadidae, 3 n. sp.

Fulgoridae, 5 n. gen., 17 n. sp.

Cercopidae, 1 n. sp.

It is interesting to note that some genera described only from the

East (India) are represented here by different species or by closely

allied representative genera. Many of the new forms are described

from N. Damaraland and Ovamboland, while Great Namaqualand

seems to agree faunistically more or less with the Cape Pro-

vince, or rather S.-Western Cape Province. There seems to be a

zoogeographical division, agreeing more or less with tropical and

S.-Hastern Africa, with representatives or allied forms from the

Oriental region. No definite distributional similarity could, however,

be laid down, as a comprehensive faunistic survey of Africa within

the Southern tropical zone and the 8.-Hastern regions has as yet not

been undertaken. The interposed arid and desert regions of the

Karroo, the Kalahari, and Bechuanaland seem to have acted as a

barrier between S.-Eastern and 8.-Western Africa. There is no doubt,

however, that S.-Hastern Africa meets Ovamboland and S8.-Western

Africa across Southern Rhodesia. Damaraland and Great Nama-

qualand constitute an area invaded from the South by S.-Western

Cape forms, and from N.-Western and §.-Central Africa by tropical

stragglers.

I wish to express my indebtedness to the above-mentioned present

and past members of the staff, and to the private collectors, who have

contributed so many interesting specimens to the Museum collections.

The 2 specimen does not differ in specific characters from the 9

specimen of U. typicain our collection. The only differential character

seems to be the acutely and characteristically produced posterior

lateral angles. As this is not sexual it is most likely a variation from

the type.

laterally on the ampliated margins and transversely across the

middle, the anterior margin slightly sinuate, the lateral margins con-

vexly rounded ; scutellum longer than broad, basally transversely

grooved, basally slightly convex, subcarinate apically, apex directed

downwards; hemelytra as broad as the abdomen beyond the middle,

with the basal costal margin slightly ampliated and reflected upwards ;

The three specimens, two males and one female, from Ovamboland

differ from Distant’s description and from the one labelled specimen

we possess in being narrower, 3-5-4 mm. across the pronotum, in

being very pilose and pubescent, in having the entire clavus with the

exception of the inner basal part, an obscure subapical spot on the

corium, four spots on the basal parts of the segments on the connexi--

vum and abdominal margin, and a transverse fascia along the base

of each abdominal segment beneath black.

As the other specific characters do not differ from the description,

the differences in colour may be considered as variations to which the

species is subject.

Winged 92: Pl. III, fig. 6. S.A.M.

The two female specimens in our collection agree in details with

our determined apterous specimens of D. tartareus Stal, except for the

fact that they are winged. As in the winged forms of other apterous

Pyrrhocoridae the corium is definitely separated from the clavus and

the apical margin passes insensibly into the membrane. The mem-

brane just reaches the apex of the abdomen and the venation is reti-

culate like that of the winged forms of Scantius forstera Fabr., and

characterised by fairly large basal cells.

This genus seems to be an isolated one, and differs from other

members of the Salyavatinae by the presence of two joints to all the

tarsi. As only a single female specimen is at hand, and the general

characters agree with those of the Salyavatinae, I assign it to this sub-

family. This insect was also found under stones in company with

T. saxatilis, to which it bears a strong resemblance.

the body below (as far as can be seen in carded specimens) brownish

ochraceous ; the metastethial regions, the bases of the spines and the

tarsi on the posterior legs more or less ochraceous; a small basal

spot on each side of the vertex, the eyes in part, the anterior lateral

margins on the face, the lateral regions of the head on each side below

the lobes of the vertex and the eyes, a large transverse fascia on each

side behind the eyes, the posterior lateral angles and some narrow,

interrupted, transverse, discal markings on the pronotum, the basal

parts, the basal half of the lateral margins and a transverse mark at

about the middle on the scutellum, the lateral pectoral regions below,

lateral surfaces on the femora and tibiae, the irregular spots and the

apices of the spines on the posterior tibiae and tarsi black; tegmina

more or less ochraceous, with a spot opposite the bifurcation of the

longitudinal vein near the costal margin, and the apical areas slightly

paler, with the punctuations, the basal part on the clavus, the basal

costal region, an infusion near the base of the discal cell, a small

callous spot on the apex of the clavus, and another larger, oval, more

elevated one opposite the claval apex nearer the costal margin, the

longitudinal veins on the apical area, and a posterior intramarginal

line black ; head, pronotum, and scutellum sparsely, and the tegmina

densely punctuated.

The head about half as long as the pronotum, with the anterior

margin somewhat produced and convexly rounded ; rostrum extend-

ing slightly beyond the intermediate coxae ; pronotum broader than

long, discally slightly convex, with the anterior margin slightly pro-

duced and convexly rounded, with its posterior margin concave to

the scutellum; scutellum about as long as broad (or very slightly

longer than broad), discally slightly depressed, with its apex acute ;

tegmina with the costal margin slightly sinuate opposite the bifurca-

tion of the longitudinal veins, with the posterior margin rounded ;

posterior tibiae with two spines (a subbasal one and a strong, prominent

medial one).

2.—A Monograph of the Formicidae of South Africa. By GEORGE

ARNOLD, D.Sc., A.R.C.S., F.E.S., Curator of the Rhodesia

Museum, Bulawayo.

(With 23 Text-figures.)

APPENDIX.

SEVERAL additions to our list have been made since the publication

of the Monograph composing Vol. XIV of these Annals. There are

also a few minor corrections and some misprints in the first two parts

which need rectification. In the following pages these addenda and

corrigenda will be arranged in their proper order according to the

pagination and the sequence of the Tribes.

I have recently had the whole of the Haviland collection, now in

the Natal Museum, submitted to me for examination by Dr. E.

Warren, Director of that Museum. The collection is preserved in

spirits and contains specimens (paratypes) of most of the species which

were sent to Dr. Forel for determination. An examination of this

material has brought to light a few novelties, and has enabled me

to add further remarks on some of Forel’s species.

PONERINAE.

TrinE CERAPACHYINI.

CERAPACHYS PERINGUEYI, Emery, var. LATIUSCULA.

Also found at George, Knysna district, (Brauns).

CrerapacHys ARNOLDI, Forel.

Bull. Soc. Vaud. Sc. Nat., vol. 50, p. 211, 9, 1914.

8, 3-5 mm. Colour similar to that of Perungueyr, but a little paler

and more reddish; the tarsi dark ochreous, the antennae yellowish

brown (not ferruginous as in Peringueyz), the club ochreous. Smooth |

and shining. Puncturation like that of Peringueyz on the head and

thorax, but the punctures smaller and shallower. The puncturation

of the petiole and abdomen much more sparse and more feeble than

in Peringueyi; the petiole more strongly punctured than the Ist

abdominal segment, the latter only slightly more strongly punctured

than the rest of the abdomen. The scapes more strongly punctured

than in Peringueyi. Pilosity shorter and less abundant than in

Peringueyt. Head slightly longer than wide, relatively narrower

behind than in Peringueyi, with the sides more convex, the posterior

angles much more prominent, and the posterior margin more deeply

emarginate. The vertex of the head is more convex. The scape is

longer, extending to, or a little beyond the middle of the head;

2nd—9th joints of the flagellum twice as wide as long (less than twice

in Peringueyt). The ventral lamella produced in its anterior half, the

projection ending in a sharp angle or tooth behind (in Peringueyr the

posterior end of the projection forms a wide and obtuse angle).

Habitat——-? Cape Province. (Ex 8.A.M. coll.)

(S.A.M., G.A. colls.)

Var. HEwIrTTI, n. var.

8,3 mm. Colour as in Peringueyr. Similar to the type of Arnoldi

but smaller, and differing from it in the following characters. . The

hairs on the body are more abundant, especially on the petiole and

abdomen. The thorax is shorter, the head (measured from the apex

of the clypeus to the occipital margin) being a little longer than the

thorax (measured from anterior margin to the brow of the declivity) ;

in the type, the thorax is slightly longer than the head. The 1st

segment of the abdomen is nearly as wide in front as behind (distinctly

narrower in front than behind in the type).

Grahamstown, (Hewitt). Type in my collection.

C. Ropertt, Forel.

Bull. Soc. Vaud. Sc. Nat., vol. 50, p. 212, 3, 1914.

8, 3:5 mm. Castaneous red. Smooth and shining. Head and

abdomen very finely and sparsely punctured. Thorax and petiole

more coarsely and more closely punctured; a median longitudinal

area on the thorax almost impunctate. Puilosity yellowish, thin,

short, and scanty, becoming almost a pubescence in parts. Head

one-fifth longer than wide, widest in the middle, the sides distinctly

convex, the hind margin concave, the posterior angles rounded but

very prominent, curved outwards and continued underneath the

hind margin of the head as prominent elongate lobes or carinae.

Mandibles oblong, as wide at the base as at the masticatory margin,

which is feebly concave. Frontal carinae close together and short.

Genal carinae very distinct. Eyes composed of a single facet, placed

in the middle of the sides. Antennae 12-jointed; antennal fossae

deep. The scape extends back beyond the middle of the head, the

2nd—9th joints of the flagellum are wider than long, the 10th as long

as wide, the apical joint fairly narrow, very little more than twice as

long as wide, as long as the 7th-10th together. Promesonotal suture

distinct ; the pronotum in front, and the declivity of the epinotum

sharply marginate. Pronotum as long as wide, one-quarter shorter

than the rest of the thorax. The latter is narrowed behind the pro-

mesonotal suture, widens out again at about the posterior fourth, and

thence narrowed again towards the brow of the declivity, which is

nearly vertical. The anterior face of the petiole is vertical and has

its sides marginate. The petiole is moderately convex above and

behind, feebly so at the sides, a little longer than wide, as wide in front

as behind; the ventral lamella produced at its base into a large,

rectangular and semitransparent lobe. The Ist abdominal segment

is two-fifths wider than the petiole, a little wider at the apical margin

than at the base, distinctly longer than wide, narrower than the 2nd

segment, the ventral portion projecting forwards at the base. Second

segment a little longer than wide.

Allied to wroughtont but much larger, the promesonotal suture

much deeper, the posterior angles of the head more prominent.

The key to the species of the 88 of Cerapachys, should be altered

as follows.

somewhat darker. Petiole and 1st abdominal segment moderately,

the rest of the body very shining. Pilosity whitish, short, decumbent

and very sparse on the head and thorax, more abundant on the

petiole and abdomen, the apical half of the latter with longer and

exserted hairs. Antennae and tarsi sparsely pubescent. Posterior

half of the head and all the thorax sparsely punctured ; the punctures

on the thorax fairly coarse, larger than those on the head. Dorsal

face of the petiole and the Ist abdominal segment fairly closely

punctate and coriaceous, the posterior fifth of the latter more sparsely

punctured. Basal half of the 2nd abdominal segment finely and

evenly punctured. Scape and flagellum finely punctured, mandibles

edentate, sparsely and rather coarsely punctured. A patch between

the eyes and antennal sockets very finely coria-

ss ceous. The rest smooth and impunctate.

Head subquadrate, one-seventh longer than wide,

ie the sides and posterior margin very feebly convex,

the posterior angles widely rounded. Clypeus and

frontal carinae as in P. Coopert, Arnold. The genal

,4--, angles in front of the eyes more acute and directed

coxa. more upwards than in that species. The scapes are

much more abruptly incrassate than in Cooperi and

are hardly three times as long as their greatest

width, barely extending back as far as the hind

margin of the eyes. First joint of flagellum as long

as wide, the 2nd-8th much wider than long, the 9th

one-third wider than long, the last joint half as long

again as the 10th. The eyes occupy one-fourth of the sides of the

head and are placed just in front of the middle. Dorsum of thorax

sharply margined in front and behind, narrowed gradually towards

the anterior third, thence ampliated and widest at the posterior third ;

about three-fifths longer than wide. The thorax is convex lengthwise

and rises gradually from front to back. The declivity is very smooth

and shining, steep, feebly margined at the sides. Petiole not quite

one-third wider than long, anterior and lateral faces vertical, the

anterior also concave transversely, the posterior face convex from

above to below and vertical. The dorsal face is moderately convex,

sharply marginate at the sides (which are feebly arcuate), and

moderately marginate and concave in front; the posterior angles

end in blunt teeth which are about as long as their basal width The

ventral lamella of the petiole is produced in front into a large tri-

angular tooth. Abdomen deeply constricted between the Ist and 2nd

segments. The Ist is narrowest at the base, a trifle wider than

long, and half as long again as the petiole, its sides convex. The

2nd segment is slightly wider and longer than the Ist, and a little

longer than wide. The coxae of the posterior pair of legs bear behind,

internally, a lamelliform and bluntly triangular process, which is as

high as it is wide at the base. This structure is also visible in Coopers,

but in that species it 1s thicker and relatively shorter.

Falls and Bulawayo.

3, (hitherto undescribed), 8mm. Black; mandibles, legs and scapes

reddish ochreous; flagellum reddish brown; the first two joints and

apices of the remaining joints paler. Sculpture and pubescence as in

the &, but the punctures are very shining and larger, particularly on

the lst abdominal segment; the punctures on the dorsum of the

epinotum and on the petiole very large and deep. Head subcircular,

about as wide as long, widest across the eyes, the posterior margin

straight. Mandibles large, triangular, acute at the apex. LHyes large,

oblique, occupying more than half the sides of the head. Antennae

filiform, thick, extending back to the brow of the declivity of the

epinotum ; the scape short, not reaching the lateral margin of the

head, about as long as the 2nd joint of the flagellum; the Ist joint

wider than long, very short, hardly one-third the length of the 2nd

joint, all the remaining joints at least twice as long as wide. Frontal

carinae parallel, well developed, almost reaching back to the level of

the posterior margin of the eyes. Ocellinot large, convex. Pronotum

convex in front ; mesonotum rather convex lengthwise, a little wider

than long; scutellum rounded posteriorly, well above the level

of the epinotum. Metanotum pointed or tuberculate in the middle.

Dorsum of epinotum widest at the base, three times wider at the base

than it is long in the middle, much wider than long; the declivity

vertical, concave from above to below, the margins sharply defined.

Petiole similar to that of the %, but more convex above and a little

narrower in front; the posterior margin only feebly tuberculate at

the lateral angles, not dentate as in the ¢. The ventral lamella is

produced at the extreme base into a long, thin spine, pointing down-

wards and blunt at the apex. Abdominal constriction fairly strong ;

the lst segment as long as the 2nd. Wings with the nervures and

stigma pale brown, the apical half smoky.

PLATYTHYREA MocqQueErysi, Emery, var. MATOPOENSIS, Arnold.

3, (hitherto undescribed),6mm. Black; antennae and legs reddish

brown, the tarsi paler, mandibles dark castaneous. Sculpture and

pubescence as in the 9, but the punctures are larger and deeper,

especially on the epinotum and abdomen ; the epinotum is also finely

coriaceous. Head subquadrate, slightly narrowed behind, the

posterior margin straight, the sides feebly convex, the posterior angles

rounded. LHyes large, occupying the anterior half of the sides of the

head; ocelli small. Mandibles large, triangular, the masticatory

margin feebly denticulate. Anterior margin of clypeus convex.

Frontal carinae slightly divergent behind, not reaching the level of

the middle of the eyes, not so distinct as in Schultzer. Antennae

filiform, extending back to about the middle of the mesonotum ;

scape short, very little longer than the 2nd joint of the flagellum ; the

1st joint as long as wide and half as long as the 2nd, the remaining

joints all about one and a half times as long as wide. Pronotum three

times as wide as long, widest behind; the promesonotal suture

arcuate. Mesonotum a little wider than long, the anterior Mayrian

furrows fairly distinct (very feeble in Schultzer). Dorsum of epinotum

about two and a half times as wide across the base as it is long in the

middle. It has a median longitudinal sulcus or row of punctures, and

the posterior angles are prominent and subdentate; the declivity is

vertical, submarginate at the sides. Seen from above, the junction

of the two faces forms a sharp and concave edge. The petiole is

shorter than in the §, little more than one-quarter longer than wide,

distinctly narrower in front than behind, convex above and at the sides,

the anterior face vertical, rounded above at its junction with the

dorsal surface. The ventral lamella of the petiole produced in front

into a rounded and more or less triangular projection. First ab-

dominal segment one-third shorter than the 2nd, (as long as the 2nd

in Schultzer). Inner margin of posterior coxae subdentate.

Essexvale, 8S. Rhodesia; taken at light. Although not captured

in company with the §%, it is undoubtedly referable to this species on

account of its general structure, sculpture and size. In my collection.

PLATYTHYREA ARNOLDI, Forel.

©, (hitherto undescribed), 13 mm. Sides of pronotum a little

straighter than in the §, but the segment is as large and of the same

shape as in the 9. Mesonotum one-fourth wider than long; the

scutellum (excluding the paraptera) pentagonal. Dorsum of epinotum

one-third wider at the base than long, very little wider there than at the

apex ; less abundantly punctured than in the 8. Wings dark brown,

rather short, (anterior wing 7 mm. long), nervures and stigma almost

black. Otherwise exactly like the §.

3S, (hitherto undescribed), 10-10°5 mm. Head a trifle wider than

ferruginous, subopaque, the apex subacute, the masticatory margin

edentate and concave. The scapes are three times as long as the 1st

joint of the flagellum. Pronotum three and a half times wider than

long in the middle. Mesonotum nearly as long as wide, sparsely but

strongly punctured in the middle. Scutellum very convex trans-

versely, as high as the mesonotum and much higher than the dorsum

of the epinotum. The latter and the petiole are very strongly and

abundantly punctured, much more so than in the § and 9. The

dorsum of the epinotum is more narrowed towards the apex than in

the 2, unarmed, but with the apical margin slightly raised. Petiole a

little shorter than in the 2 or 8. Wings almost hyaline in the basal

half, fuscous brown in. the apical half, the nervures pale brown, the

pubescence, but hardly longer. Mandibles finely denticulate; the

clypeus, fused with the frontal carinae, forms a subrectangular lobe in

front ; the frontal carinae are longer than half the head, and together

form a projection which is flat on top, with abrupt margins ; it starts

in an acute angle in front, widens towards the third of its length, and

then narrows and gradually descends posteriorly. Hyes fairly large,

with large convex facets (at least 30 in the $). Ocelli present in the 9.

Antennae 9-jointed. Thorax without sutures in the §, the epinotum

obtusely angulated on each side of the brow of the declivity, the latter

concave. In the 9, the angles of the epinotum are more prominent.

and opposed to the lst abdominal segment,’ but only about half its

surface is articulated to that segment. First abdominal segment as

long as the thorax; separated by a well-marked constriction from

the 2nd segment, which is shorter; the remaining segments very

narrow. Wings yellowish with pale nervures. $ 2-5 mm.,?3 mm.

This species has to be added to our list on the evidence of a 9, taken

by myself in the Rain Forest, Victoria Falls, which agrees in every

particular with the above description except the puncturation. The

punctures in this specimen may be described as deep, being nearly as

deep as they are wide. In my collection.

Pubescence very fine and abundant. Erect pilose hairs absent; dull.

Densely and finely punctured. Head distinctly longer than wide,

narrowed in front, the posterior margin rounded, the sides nearly

straight. Hye composed of 5 or 6 facets, placed in the anterior third

of the sides. Antennae with 8 (9) joints, the 5th and 6th fused

together. The scape, dilated at the apex, reaches the middle of the

head ; 2nd and 3rd joints of flagellum twice as wide as long, indistinct,

the following joints increasingly wider. The last joint very large,

ovoid, about two-thirds longer than wide. Frontal carinae completely

fused into a single foliaceous plate, forming a raised triangular lobe,

with the summit rounded in profile, and not extending beyond the

anterior third of the head. Anterior margin of the clypeus transverse

in its median fourth. Mandibles punctured, feebly denticulate behind,

with a concave masticatory margin which ends in front in a strong

triangular tooth. Thorax raised, feebly convex, dorsal surface flat,

submarginate and without sutures. Declivity truncate, marginate

and subdentate. Petiole about three times as wide as long, rounded

above, very convex in front, with a large tooth below.”

TrisE PONERINI.

CENTROMYRMEX CONSTANCIAE, Arnold.

In the opinion of Dr. Forel, to whom I sent specimens of this species,

the name must be sunk as a synonym of C. sellaris, Mayr, (Ent.

Tidskr., p. 230, 1896). On the other hand, Dr. Santschi is of the

opinion that the forms are distinct. Not having seen the type of

sellaris, I am unable to pronounce any opinion on the subject

myself. |

Recently Dr. Santschi described as a new species (C. Arnoldi, Rev.

Zool. Afr. 6, p. 229, 1919) some specimens of Constanciae which I had

collected in the Amatongas Forest, P.E.A. In a later paper he

admits that it is at the best only a slight variety of Constanciae.

(Ann. 8. H. Belg., vol. 60, p. 8, 1920.) For my part, I fail to detect any

difference between these specimens and the type of Constanciae. The

3 of the latter has been briefly described by Santschi under the name

of Arnoldi. The following is a more detailed description.

3, (hitherto undescribed), 5-5-3 mm. Black; the base of the abdom-

inal segments narrowly dark brown, legs brown, tarsi pale yellowish

brown, antennae brown and becoming brownish yellow towards the

apex, the lst joint of the flagellum brownish yellow; shining. Legs

and antennae pubescent, the pubescence on the latter decumbent and

shorter than on the legs. Whole body clothed with a short, erect,

coarse, and black pilosity, intermixed here and there with some longer

and finer hairs ; on the abdomen the coarser pilosity is less abundant.

Head coarsely punctured on the vertex and frons, also finely striate,

transversely so above, more or less longitudinally on the clypeus.

Pronotum closely and finely punctured, the mesonotum more closely

punctured, the punctures becoming larger and deeper towards the

posterior margin, also finely and transversely rugose in the middle

over its posterior third. Scutellum longitudinally striolate. Hpino-

tum and petiole smooth, abdomen sparsely and finely punctured.

Head, seen from above, a little more than twice as wide as long; seen

from in front, transversely oval and about one-fourth wider than high ;

seen from the side, thicker anteriorly. The eyes occupy the anterior

half of the sides. Mandibles elongate triangular, small, not meeting

EUPONERA HAVILANDI, Forel, and PErincury1, Kmery

In my remarks on the first of these two species, I pointed out that if

the unknown ¢ of Peringueyi should eventually prove to be similar to

that of Havilandt, it might be necessary to separate those two species

from the rest of the genus Huponera, under the subgenus Hagensia,

or to re-erect that as a distinct genus. Prof. Emery has expressed the

opinion, (7 lett.), with which I agree, that the presence of toothed claws

in the § and ¢ should be sufficient grounds for such separation. It is

true that the § of Haviland: resembles that of caffraria, e.g. in the

possession of the spined pygidium and closed radial cell, but the

structure of the claws in both sexes, the shape of the petiole in the 4,

and the marginate pronotum, the mandibular fovea and the large size

of the %% of both species, justify the erection of a genus distinct from

Kuponera. These two species are therefore to be placed under the new

genus Hagensia, characterised as follows :—

Genus HAGENSIA, Forel (Arnold emend.).

é Characters.

83. Claws with a distinct tooth. Middle and hind tibiae with two

calcaria, the outer small, the inner large and pectinate. Mandibles

with the masticatory margin long, beset with alternatingly large

and small teeth, and with a transverse or oblique elongate fovea near

the base. Cheeks without carinae. Scape cylindrical. Thoracic

sutures distinct. Pronotum margined laterally. Node of petiole

truncate behind, the junction of the anterior and posterior faces

forming a sharp edge. Abdomen truncate at the base and sloping

forwards; the lst segment with a distinct tooth below at the base.

$. Antennae 13-jointed, long and filiform ; the scape short, shorter

than the 3rd joint of the flagellum, the 1st joint shorter than the scape.

Mandibles edentate, oblong and very small. Frontal carinae obsolete.

Pronotum very little exposed above; Mayrian furrows not defined.

Epinotum very bluntly bituberculate. Petiole long, much longer

than wide, the node feeble. Pygidium spined. Middle and hind

tibiae with two calcaria. Claws with a small tooth. Radial cell

closed.

On page 69 I pointed out that the Natal forms differed from those

taken at King William’s Town. The examination of further material,

including specimens which were taken at Durban and which agree

entirely with Forel’s description, has enabled me to clear up the con-

fusion and to recognise the existence of two races of the type species.

Hacensia Havitanpi, Forel, race GODFREYI, n. r.

8, 13 mm. Larger than the type of the species from Natal.

Moderately shining all over; very finely and evenly punctured,

the spaces between the punctures smooth, not reticulate and sha-

greened as in the type of the species. Mandibles smooth and shining,

the fovea near the base much deeper and wider. The longitudinal

depression at the summit of the declivity of the epinotum is much

deeper and ends more abruptly. The declivity is also narrower than

in the type of the species. The sides of the head are more convex,

and the head is shorter or only one-eighth to one-ninth longer than

wide (one-fifth in the type of the species). Otherwise like the type of

the species. Pirie, King William’s Town, (Rev. R. Godfrey) ; Grahams-

of a very dense, regular, microscopic, and reticulate puncturation on

the head, and thorax, similar but less dense on the abdomen. The

latter has a sparse and very shallow puncturation superimposed.

The whole body, excepting the base of the abdomen, is entirely dull.

Pubescence much finer and shorter than in the type species, forming

only a microscopic down. Mandibles as in the type of the species,

but with the foveae deeper and more transverse in direction. The

anterior margin of the clypeus lacks the obtuse angle or tubercle which

is present in the type, and the suture which separates the clypeus from

the rest of the head is shining and deeply impressed (shallow in the

type of the species). The frontal carinae are not elongated behind

like an eyebrow as in the type of the species. The frontal sulcus is

much deeper and ends abruptly in front and behind. The pronotum

is widest in front, and wider than in the type species, very sharply

marginate all round, the margin projecting slightly over the vertical

sides. Mesonotum wider than long (about as long as wide in the type).

Dorsum of epinotum wider and flatter, the declivity more sharply

margined, very little higher than wide below (nearly two-thirds higher

than wide below in the type), not longitudinally impressed at its

summit. The posterior face of the scale lacks the slight tubercle

below the apex which is present in the type of the species.

This must be sunk to a synonym of P. mandibularis, Smith. An

examination of a specimen sent to me by the author shows that

it does not differ from the small variety of mandibularis, which is found

in the coastal regions of the eastern part of the Cape Province. The

species becomes progressively larger the farther it is from the coast,

and a complete transitional series can be found from the smallest

(Durban, etc.) to the largest or typical mandibularis, such as is found

in Rhodesia.

It is, therefore, also open to doubt whether the species mznor,

the frontal carinae fanwise longitudinally striate, the striae curving

round outwardly, but laterally not extending to the outer edge of the

antennal hollows, and posteriorly not beyond the anterior half of the

head. Mandibles sparsely and finely punctured, the scapes very finely

so. Dorsum of epinotum superficially coriaceous ; otherwise impunc-

tate. A sparse, yellowish, and short pilosity present all over, very

scanty on the thorax. A very scanty pubescence on the mandibles.

Head, excluding the mandibles, one-sixth longer than wide across

the level of the eyes, where it is widest ; itis, however, not wider there

than across the occipital lobes by more than the length of the Ist joint

of the flagellum. The sides of the head behind the eyes more deeply

The upper or preapical tooth is as

long and as acute as the apical, and the subapical, which springs from

the base of the apical is about half as long as the other two. The

scapes extend back as far as the apex of the occipital emargination,

but do not reach as far as the posterior angles of the head; 3rd—5th

joints of the flagellum about as long as wide, all the rest longer than

wide. Eyes small, not longer than the 3rd joint of the flagellum,

composed of about 15-18 indistinct facets. Pronotum narrower and

promesonotal and mesoepinotal sutures shallow but very broad. The

mesonotum (excluding the suture) about half as wide again as long (at

least twice as wide as long in punctaticeps). The dorsum of the epi-

notum is as long as the pronotum, much narrower at the base than at

the apex (shaped like an isosceles triangle), more convex transversely

in its basal half than in punctaticeps, and ending in stronger and more

prominent teeth than in that species ; the declivity is vertical, shorter

Head, seen from in front, semicircular, the eyes occupying the

anterior half of the sides. Scapes half as long again as the Ist joint of

the flagellum. This joint is as long as wide, all the other joints much

longer than wide. The scapes extend laterally barely beyond the

inner margin of the eyes. Clypeus obtusely carinate. Mandibles

very small or atrophied. Pronotum slightly exposed above. Meso-

notum wider than long, strongly convex above and infront. Scutellum

gibbous, less than half as long as the mesonotum. Metanotum

species. I therefore give figures of the thoraces and petiole of the two

forms. The sculpture of the pronotum, even in examples from the

same nest, varies between the two extremes of being transverse or

longitudinal, the posterior striae becoming more and more arcuate

anteriorly till at last they occupy a median and longitudinal position,

the anterior striae being arranged more or less concentrically and

outside them.

‘“ Distinguished from the type as follows: The head is distinctly

of a reversed trapeze-shape, much narrower behind than in front.

Its posterior margin is about one-third narrower than the anterior,

even in the smallest 38 it is a little narrower. The thorax is much less

flattened above, hardly very obtusely submarginate. Seen in profile,

the pronotum in front and the epinotum behind are convex, and pass

into the dorsum by a much more gentle curve. The petiole is wider,

one and a half times wider than long; its angles less rounded. The

2nd-9th joints of the flagellum are at the most only one and a half

times wider than long (at least twice as wide as long in the type of

braunst). Moreover, the puncturation of the head, although sparse,

is much more distinct; that of the thorax is also a little stronger,

whereas that of the petiole, which is a little more shining than in the

type, is less dense.”

“In greater part like the type, but differing in the following

features. The posterior margin of the head is strongly convex; the

eyes are smaller and less convex. The head is not wider than the

thorax. The petiole is wider and shorter than in the type, nearly

one and a half times wider than long. The colour of the thorax and

wings is also darker. It differs from montanus, Sants., by the total

absence of an erect pilosity, on the abdomen as well as on the thorax

and petiole. Moreover, it differs from montanus and from the type

of diadema by its genital armature. The stipes are not truncate at

the apex as in montanus, but bevelled, almost as in diadema. The

volsellae bear on one side a row of hairs and are slightly widened at

the apex, which are strongly punctured and truncate curvedly. The

sagittae are also somewhat swollen at the apex, which ends below in a

sharp point. The subgenital plate has the same shape as in montanus.”’

and the apex of the abdomen. Pubescence microscopic, very short

and scanty. Head rectangular, one-fifth longer than wide, as wide in

front as behind, the sides convex, the posterior margin straight.

Mandibles smooth, shining, finely and very sparsely punctured.

Anterior margin of clypeus feebly emarginate in the middle. The

scapes fall short of the hind margin by about one-fourth of their

little wider than long and shorter than the declivity. Both thoracic

sutures feeble. Scale fused with the petiole, tongue-shaped.

2, (hitherto undescribed), 6°8 mm. The structure of this insect is

exceedingly remarkable, recalling in the shape of the head and

epinotum that of Rhoptromyrmex transversinodis 2, and totally dis-

similar to the other known 99 of this genus.

Black, dull, the basal two-thirds of the 2nd and 3rd abdominal

segments smooth, shining and microscopically reticulate. The rest

of the body very finely and densely reticulate-punctate (much finer

than in the &), also more or less longitudinally rugulose or striato-

rugulose on the head and mesonotum above; these parts have also a

shallow puncturation superimposed. Epinotum striato-rugose trans-

versely above. The posterior faces of the two nodes similarly but

less strongly sculptured. A fine, yellowish, oblique and fairly long

pubescence present, not very abundant, decumbent on the legs and

scapes. Pilosity yellowish, very sparse on the head and thorax,

longer and more plentiful on the nodes. Apical margins of the

abdominal segments with a dense tuft of long hairs at each corner.

Head about as wide as long in the middle, very convex above, the sides

almost parallel. Behind the ocelli the back of the head is convex and

vertical, merging below into a horizontal shelf which is formed by

a backward prolongation of the posterior margin and lateral lobes.

The shelf and the lobes on each side of it are deeply excavated. The

lateral lobes extend outwards and far backwards and are widely

truncate at their apices. Mandibles strongly and longitudinally

striate, sparsely punctured, 4-dentate. Anterior margin of the clypeus

emarginate in the middle, the posterior margin not defined, the clypeus

ends behind in a tubercle placed just between the anterior ends of

the short and parallel frontal carinae. The scapes barely extend back

as far as the level of the apices of the lateral lobes. The thorax is

very high, almost twice as high as wide between the parapsidal sutures,

the sides vertical. The anterior half of

the mesonotum is very strongly compressed,

and projects forwards over the pronotum

and the hind margin of the head. Seen

from above, the anterior half of the

mesonotum is almost cristate in the

middle and semi-elliptical in outline. The

sides of the mesonotum external to the

parapsidal sutures are steep and form

a distinct angle at the sutures with the flat portion above. The

thorax is long and narrow, nearly three times longer than wide.

The upper surface of the epinotum is concave transversely and

moderately convex longitudinally. The sides of the declivity are

marginate, the margins being abruptly produced above into thin,

slightly divergent and more or less semicircular walls or flaps which

end in front at about the middle of the epinotaldorsum. These cristate

flaps are about twice as long as high. Dorsal edge of the Ist node

thick and shallowly emarginate ; the dorsal face of the 2nd node flat

or slightly concave, two and a third times wider than long. Deéilated.

Bulawayo. Seven specimens, taken with the $9 in two very popu-

not been taken with the 8%, one might have regarded it as the type of

regard these 9? as parasitic forms analogous to such a species as

Bothriomyrmex meridionalis, which is parasitic on Tapinoma erraticum.

petiole is almost entirely effaced, and the surface is therefore much

more shining. The mesonotum and epinotum are also much more

superficially reticulate. The head is narrower, its sides less convex,

the hind margin more deeply emarginate, distinctly narrower behind

than in front. Antennae blackish brown, not reddish brown as in the

type of the species, the joints of the flagellum more slender. The

dorsum of the epinotum is narrower, or twice as long as wide, less

widened behind than in the type, and also much more shallowly

excavated. Nodes of the petiole narrower, the upper edge of the Ist

node less rounded from front to back.

notum, very finely on the petiole. Abdomen moderately shining,

microscopically reticulate, sparsely and shallowly punctured, the

punctures bearing pubescent hairs. A few short rugae radiate out-

wards from the ocelli, and there is a slight rugosity at the base of

the mesonotum. Abdomen and legs with a sparse and decumbent

pubescence, absent elsewhere. Pilosity yellowish and sparse every-

where. Scapes very thick and much swollen in their apical halves,

two and a quarter times longer than their apical width ; flagellum

densely punctured and pubescent, all the joints, except the last

two, swollen in the middle; the 2nd joint nearly half as long again

as the 3rd. Median area of clypeus quadrate, feebly convex or

nearly flat. Mandibles shining, with 3 or 4 teeth. Eyes very slightly

convex, occupying the middle third of the sides. Dorsum of epinotum

very short, merging gradually into the declivity. The upper half

of the declivity is reticulate-punctate and dull, concave transversely

and subvertical, the lower half is vertical, smooth and shining. First

node, seen from above, one and two-thirds as wide as long, the upper

face shallowly emarginate ; 2nd node a little wider than the Ist, two

and a half times wider than long, convex from front to back, feebly

concave transversely. Abdomen subglobose, a little longer than wide,

very convex above, much more robust than usual in this genus.

Wings hyaline, tinged with yellow in front, the costal and subcostal

nervures dark brown. Quite distinct from all the other known 3d

for me by Dr. Forel. Itis, however, quite different from Emery’s race,

and I therefore propose for it the name ocellatum (race of salamonis).

Dr. Santschi has given the following description of the true australe,

but based chiefly on its race Havilandz, (see Ann. Soc. Ent. France,

vol. 85, p. 283, 1916) :—

“8 major, 2°55 mm. Reddish brown, abdomen black, slightly

brownish at its base. Mandibles, clypeus, sides of the mesonotum

and lower surface of the petiole reddish ochreous. Cheeks, frontal

carinae and antennal pits finely striated, the rest of the head smooth,

with a fairly strong but sparse puncturation. Thorax and petiole

densely reticulate-punctate as in M. salamonis (this sculpture is more

or less effaced on the promesonotum, which may be smooth and

shining). Abdomen and legs smooth. Pilosity erect and yellowish,

fairly abundant on the abdomen, sparser on the thorax and head.

The legs and antennae have only a decumbent pubescence, which is

also present on the head, and more sparsely on the body. Head a

little longer than wide, the sides feebly convex, the hind margin widely

concave. The head is generally wider in front than behind, but it

becomes rapidly as wide in front as behind in the smaller individuals,

in which it appears relatively narrower. The eyes, placed between

the anterior third and the middle of the sides, are fairly flat; their

long diameter is as long as the distance between them and the anterior

angles of the head. Clypeus entire, strongly concave between its two

carinae, which are widely separated, almost contiguous with the

frontal carinae and continued at the sides into the anterior margin.

Mandibles striate, 3-dentate. The scape does not quite reach the

hind margin of the head. Third to 8th joints of the flagellum wider

than long. The club not very thick, its 2nd joint only a little wider

230 Annals of the South African Museum.

and nearly as long as the preceding joint. Promesonotum convex,

without distinct sutures on its dorsum. The emargination of the

profile of the thorax a little weaker than in gracillamum (much the

same as in salamonis subopacum, which this species resembles fairly

closely in the shape of the thorax and petiole). Epinotum a little

convex, passing by a gradual curve from the dorsum into the declivity.

First node cuneiform, rounded above, convex below as in minutum,

the peduncle in front shorter than the node, bearing below, near the

posterior articulation, a small and obtuse tooth. Second node small,

lower than the Ist, wider than long. Abdomen oval, narrower in front.

8 media, 2-2-1 mm. The head elongate rectangular, the sides more

parallel, with a more or less superficial reticulation on the occiput

which may extend as far as the striae. The two faces of the epinotum

are more distinct and more marginate.

% minima, (= var. laeviceps, Emery). The head is smooth and

shining as in the 8 major, narrower than in the § media, but slightly

wider behind the eyes, concave behind, the epinotum almost as much

rounded as in the 8 major, the sculpture of the thorax hardly more

feeble, the joints of the flagellum a little shorter.

9, 4:5-5 mm. The head is entirely dull, as also the 1st abdominal

segment which is sculptured like the petiole. Otherwise as in Havi-

brown. More feebly sculptured than the type of the species, and

more shining. Pilosity as in the type of the species but much scantier,

slightly more rounded. First node of the petiole more conical, the

apex less rounded.

to be remarked that these specimens were named for me by Dr. Forel

himself. The size varies between 2-8 and 3-4 mm., and the larger

specimens cannot be referred to the var. notula of setuliferum as

suggested by Santschi. The var. notula has a shorter head and a

pubescent. Head, including the mandibles, about one-fourth longer

than wide, the sides feebly convex, the posterior margin shallowly

concave (not straight as stated in Santschi’s description). Median

area of clypeus longer than wide in front, distinctly bicarinate, the

anterior margin almost straight. Frontal carinae very short. The

scape falls short of the occipital margin by nearly twice the length of

the Ist joint of the flagellum. The 2nd joint of the latter is as long as

wide, the 3rd—7th wider than long. Promesonotum moderately

convex, the promesonotal suture obsolete above, the mesoepinotal

suture deep. Dorsum of epinotum fairly flat lengthwise, moderately

convex transversely, about one-third longer than wide, fully half as

long again as the declivity. In profile, the dorsum and declivity form

a continuous curve. First node of petiole subconical, higher than

long below, one-third longer than its peduncle, rounded above. Second

node lower than, and not wider than the Ist, transversely oval, about

one-third wider than long.

suture consequently narrower. The dorsum of the epinotum is

narrower at the base than in punctaticeps, and the declivity is less

oblique, more distinctly delimited from the dorsum, which it equals

in length. The Ist node of the petiole is longer and rounder above,

and its anterior face is oblique, not vertical. The promesonotum is

one-third longer than wide (barely one-quarter in punctaticeps). The

eyes are smaller. The anterior margin of the median area of the

AEROMYRMA TRAEGAORDHI, Santschi.

Page 257. In the Ann. Soc. Ent. France, vol. 85, p. 285, 1916, Dr.

Santschi placed this insect in synonymy with Aeromyrma (Solenopsis)

semilaeve, Mayr, adopting the opinion of Emery. However, in the Bull.

Soc. Vaud. Sc. Nat., vol. 52, p. 338, 1919, he reverts to his original view

and considers that Traegaordhi is to be regarded as a distinct species.

_ In the same paper that author has described several new forms of

Oligomyrmez. As it is exceedingly difficult to appreciate the details

of structure in these very minute insects without making transparent

balsam mounts, and as I have not sufficient specimens of all the

species to spare for that purpose, it seems preferable to copy Santschi’s

own descriptions, rather than to draw up new ones myself.

All the species which I have seen in life have been found under

stones or logs, or under the bark of fallen and decayed trees, in very

moist situations. They are all strongly photophobic, and, considering

their size, very quick in their movements. The soldier caste does not

appear to be of much importance in the economy of the species, as it

is rarely that more than two or three can be found in a nest.

It should be noted that Aeromyrma was erected as a genus distinct

from Oligomyrmex on account of having 10-jointed antennae instead of

the 9 which is found in the latter genus. However, since it has been

found that O. debilis, Santschi, has a 2| with 10-, and a & with 9-jointed

front. Head striate, more strongly so in front, with large scattered

punctures ; the frons, middle of clypeus, mandibles (a few striae at

their base), the dorsum of the pronotum, of the 2nd node and of the

abdomen, smooth and shining. Epinotum, mesopleurae and rest of

the petiole reticulate-punctate. Pilosity fine, curved, fairly abundant,

especially on the head, where it is only half as long as on the body.

Head rectangular, nearly one-fourth longer than wide, the angles

well defined, the sides feebly arcuate, the posterior margin straight.

Kyes indistinct. The frontal carinae extend to the anterior third of

nearly one-fourth longer than wide, the sides nearly straight, the

posterior margin hardly concave, the angles widely rounded. The

eyes, very mediocre and feebly convex, are placed in the anterior

third of the sides. Antennae 10-jointed, the scape not reaching the

anterior third of the head. Frontal carinae fairly distant, furnished

with raised lobes which cover the antennal sockets. Clypeus smooth

in the middle, striate at the sides, moderately lobate in front and

feebly excised in the middle. Behind it projects widely between the

frontal carinae ; the latter are continued along it in front as two feeble

and convergent carinae. Frontal area deeply impressed. Mandibles

smooth, with 5 or 6 teeth. Promesonotum globose, the suture in-

distinct above. Mesoepinotal suture not deep above, more marked

at the sides. Hpinotum deeply channelled from its base to the apex.

The floor of this excavation is a little convex from back to front, but

its walls are raised and form in profile a subdentate angle, whence the

dorsum of the epinotum appears a little longer than the declivity. First

segment of the petiole as high as long, the node rounded at the summit,

its anterior face longer than the peduncle, the latter with a small

Mandibles and scapes very dark reddish brown, the tip of the last joint

of the flagellum ferruginous, the rest of the body black.

Pilosity longer and much more abundant than in the type of the

species, especially on the thorax and abdomen, the hairs black. The

sculpture on the head is similar to that of the type, but the rugae are

stronger and a great deal more prominent. The promesonotum has

a strong median carina and 4 or 5 longitudinal rugae on each side of

same, and 2 or 3 transverse rugae on the anterior margin. The base

of the abdomen is microscopically coriaceous and dull. The pro-

mesonotum is relatively wider than in the type of the species, a little

wider across the anterior angles than long in the middle: the pro-

mesonotal suture clearly defined on the dorsum. The epinotal

spines are horizontal and parallel, a little longer and distinctly thinner

at the base than in the type species. The peduncle of the 1st joint

of the petiole is thinner and longer, straight when seen from the side,

not arcuate near the base as in the type of the species. Otherwise

Race PILOSA, var. ANGUSTITHORAX, Ni. V.

8, 6 mm. Piceous, mandibles, thorax and peduncle of petiole

reddish dark brown. This variety differs from the type of the race as

follows. The striae on the middle of the back of the vertex are almost

obsolete. The longitudinal striae on the pronotum are wider apart,

the three middle ones strongest, the space between them shining.

Base of abdomen smooth and shining, not reticulate and dull as in the

race. The posterior margin of the head is moderately convex, nearly

straight in the race. The eyes are decidedly more prominent and placed

farther back, their distance from the hind margin being equal to about

their long diameter, (in the race fully one and a half times their long

diameter). The basal lateral lobes of the epinotum are much less

produced outwardly, the dorsum of the epinotum being almost

parallel-sided and longer than wide, whereas in the race the base of

the dorsum is distinctly angulated outwards on each side and is as

wide there as long in the middle. Seen in profile, in race pilosa the

dorsum of the epinotum slopes downwards from the mesoepinotal

suture to the apex of the spines, whereas in the variety it is hori-

zontal or directed slightly upwards. The promesonotal suture is

obsolete (distinct in the race). The nodes of the petiole are narrower,

the Ist, seen from above, being fully one-third longer than wide, (as

long as wide in the race).

Trine THTRAMORIINI.

Genus TETRAMORIUM.

Since the publication of Part 3 of this work, several new forms have

been discovered, necessitating a complete revision of the key to the

species. More especially is this the case in the quadrispinosum and

sericewentre group.

The form previously described on page 278 as Blochmannt, race

continentis, Forel, although so determined by Dr. Forel himself,

cannot be identified with that race; in addition, the discovery of

several intermediate varieties from many parts of the African region

has made it possible for Dr. Santschi to revise the classification of the

group, (Bull. Soc. Hist. Nat. Afrique du Nord, vol. 9, pp. 121-132, 1918).

This revision is valuable, especially in emphasising the close relation-

ship between quadrispinosum and sericeiventre, which are indeed no

more than the extremes of one species, characterised by the gradual

elimination, or addition, of sculpture. In some cases it is therefore

almost a matter of personal opinion as to whether a form should be

attached as a race or variety to either one or the other of those extremes.

On the other hand, it seems to me that Santschi has placed too much

reliance on the nature of the fine sculpture of the abdomen. The

effect of this sculpture, due to an exceedingly delicate and microscopic

striolation, is plainly appreciable under a low-power, giving the

integument a dull silky gloss, but the direction of the fine striae,

whether transverse or longitudinal, cannot as a rule be determined

with a magnification of much less than 60 diameters.

T. Bequaerti, Forel, and T. Gladstoner, Forel, are two other species

which are closely attached to the quadrispinosum-sericewentre group.

The form described on page 278 as continentis should be transferred

to sericewentre, Hmery, as the var. Vascor, Santschi. The form Gamavi,

Santschi, being the commonest form in 8. Rhodesia, has been used in

the following description as a basis for comparison with the others.

My paratypes of this variety (collected from the same nest as the

8, 3:5-3-8 mm. Head burnt-sienna brown, distinctly of a paler

colour than the thorax and petiole, which are dark castaneous brown.

The abdomen is of the same colour as the thorax, except on the basal

third, where it is paler and of a burnt-sienna brown, or ferruginous,

(“roussatre,’ Santschi). The legs and antennae are brownish ochreous,

the femora somewhat darker. The head has a few whitish and erect

hairs, chiefly on the front, the thorax two or three in front, the nodes

of the petiole with two each near their posterior margins, and the

abdomen with a few on the apical half, otherwise the insect is nearly

glabrous.

The fundamental sculpture of the head, thorax and petiole consists

of a fine and close reticulate puncturation. The sides and back of the

head have a few rugae superimposed, wider and coarser in front of the

eyes, more or less anastomosed or reticulate, leaving round and shallow

pit-like areas in between. The space between the frontal carinae and

the vertex is longitudinally striate. The clypeus is rugulose and

strongly carinate in the middle, the mandibles closely and longitudi-

nally striate and dull. On the dorsum of the thorax there is a super-

imposed sculpture of rugae, chiefly longitudinal on the pro- and

mesonotum, becoming less distinct or effaced towards the posterior

half of the mesonotum ; the dorsum of the epinotum with a few more

or less transverse rugae. The sculpture is strongest near the anterior

border of the pronotum, which is marginate. The sides of the thorax

are more or less longitudinally and feebly rugoso-striate. The nodes

of the petiole are shallowly pitted, more closely at the margins than in

the middle. The lst segment of the abdomen is microscopically

rugulose near the base, longitudinally striolate or aciculate all over.

Head quadrate, slightly longer than wide, and a little wider than the

prothorax. Mesoepinotal suture wide and shallow, the epinotal teeth

a little longer than the episternal, shorter than the distance between

their bases. The dorsum of the epinotum, not very clearly delimited

from the sides, widens towards the apex and is nearly twice as long as

wide at the base. First node of the petiole as wide behind as long,

narrowed in front; 2nd node cupuliform, widest behind, about one-

third wider than long and equally wider than the lst. The whole

body dull.

This variety, described on p. 280 as a var. of continentis, must like

that race be transferred to quadrispinosum. The race elegans, Santschi,

more than a slightly paler colour of the head ; it is also derived from

the same locality, Willowmore, C.P.

8, 3°8-4 mm. Pitch black; antennae and mandibles dark cast-

aneous brown, the tibiae dark brown with the basal third paler or

rusty red, tarsi dark brownish ochreous. Shining, the abdomen

except at the base, strongly so. The sculpture of the head is similar

to that of the type of the species, but the very fine fundamental

reticulation is totally absent, (except near the occupital margin), being

replaced by a more or less longitudinal rugulosity. The striae on the

vertex between the frontal carinae are stronger and more widely

spaced. The sides and posterior half of the head are sparsely, but

distinctly, pitted. The pits are entirely wanting in the type of the

species. The fundamental sculpture of the thorax and petiole is a

very fine and superficial reticulation. The shoulders of the pronotum

laterally, a round spot on the mesopleurae and the declivity of the

epinotum lack this reticulation and are quite smooth. Pronotum with

some widely spaced, thin and longitudinal striae, the anterior margin

slightly rugose, the dorsum of the epinotum transversely and very

superficially striate, the sides of the thorax obliquely striate, the striae

fine and irregular. Nodes of petiole a little dull and coriaceous at the

sides, sparsely pitted above. Basal 4th of abdomen microscopically

reticulate-rugulose and only moderately shining. Legs shining.

Posterior angles of the head less rounded than in the type of the

species, the pronotal shoulders more pronounced. Mesoepinotal

impression deeper than in the type of the species, the dorsum of the

epinotum narrower and less convex transversely, more distinctly

delimited from the sides. The epinotal teeth relatively longer, a little

longer than the episternal, and directed more upwards. The Ist node

is only one-fourth longer than wide, more convex-sided than in the

type of the species ; its anterior face is vertical, not oblique and merg-

ing gradually into the peduncle as in the type of the species.

This race differs from the type of the species chiefly in the larger size,

the black colour, the pitting of the head, and the shape of the Ist node.

Some confusion has arisen as to the provenance of this insect,

probably owing to the specimen having become loosened from its

mount during transit through the post. Santschi remarks that it was

received with T. quadrispinosum, race elegans, (=eudoxia), and that

owing to its size, sculpture, etc., he regards it as a distinct species,

probably parasitic. He also says that it comes from Natal, (Haviland

leg.). This is erroneous, the 8% specimens with which it was sent to

Dr. Santschi, and mounted on the same card, being the race continentis

of servcewventre. In my opinion, it is the female of that race. Possibly

owing to its rather unusually small size, (3-5 mm.), the same as that

of the worker, one may assume that it exhibits a temporary social

parasitism in the founding of its nests, similar to many palaearctic

ants with microgynous females.

A peculiar species characterised by its unusual habits and by the

very regular sculpture of the head, by the absence of a trenchant ridge

behind the lateral pieces of the clypeus, and by the shape of the

petiole.

It is a highly myrmecophagous species, preying chiefly on the 3%

of small Pheidoles, (punctulata, Arnoldi, etc.), but also occasionally

on Monomorium and other Tetramorium. At Umtali several nests

were examined. All round the entrances to the nests the ground was

strewn with the carcases of other ants, and workers were seen coming

in from all sides, each one carrying in its jaws some unfortunate ant

victim, usually gripped behind the head or between the epinotum and

petiole. Type in my collection.

8,4:8-5-l1 mm. This differs from the type of the species as follows :—

The colour is black; base and apices of the femora, tibiae, tarsi,

’ mandibles and antennae more or less ferruginous. The sculpture is

much stronger, especially on the head, which is very evenly and

longitudinally striate, the spaces between being about 2 to 24 times

wider than the striae. The mesoepinotal suture is distinct and the

sides of the epinotum are vertical, the dorsum thereby sharply mar-

ginate at the sides, parallel-sided and concave transversely. The

spines are less divergent. The Ist node of the petiole is reticulate-

punctate, and has also some strong rugae superimposed concentrically ;

the 2nd node transversely rugose, its ventral surface produced on each

side into a strong triangular tooth as long as its basal width (much

longer than in the type of the species). The basal third of the

abdomen is longitudinally rugulose.

2, 7 mm. Mesonotum longitudinally striate, with finer striae in

the spaces between the large striae. The suture between the scutellum

and the paraptera deeply clathrate. Epinotal teeth shorter than in

the %, shorter than their basal width, horizontal and not divergent.

Dorsal face of the lst node flat and almost quadrangular, the sides

feebly convex, the anterior and posterior margins straight, one and

three-quarter times wider than long. Second node like that of the 9, less

convex transversely, half as wide again as the Ist, and at least twice as

wide as long. Wings brownish yellow, nervures and stigma ochreous.

S. W. Africa (R. W. E. Tucker).

In one specimen, ¢, taken on the same occasion as the others, the

epinotum has the sides oblique and convex like the type of the species,

and the dorsum is neither marginate laterally nor excavated. The

colour of the type of the species is described by Emery as piceous, but

in the paratypes in the 8. A. Museum, the colour is not darker than

chestnut brown.

femora (except at the base and apex) darker or reddish brown. In

some specimens the apex of the abdomen is almost piceous. Head,

thorax and petiole moderately shining, the spaces between the rugae

quite shining. Legs and abdomen shining, the basal fourth of the

latter somewhat dull, longitudinally and closely striate and shallowly

punctured. Pilosity long, erect and abundant all over, including the

legs and antennae, the hairs truncate or very blunt at their tips and

yellowish white. ‘The hairs on the anterior margin of the clypeus and

on the apex of the abdomen longer and pointed. A scanty pubescence

present only on the flagellum. The sculpture of the head and thorax

like that of Emeryz, race cristulatum, but the mesonotum and epinotum

are just as coarsely rugoso-reticulate as the pronotum, and the longi-

tidinal striae on the middle (transverse) third of the head are divergent

behind. Sides of the thorax longitudinally rugoso-striate. Nodes

of petiole coarsely and irregularly rugose. ‘Tibiae and scapes finely

and longitudinally striolate and fairly dull. Head quadrate, as wide

margin almost straight or only very shallowly concave in the middle,

the posterior angles widely rounded. Clypeus twice as wide as long,

the anterior margin widely and deeply emarginate, with about 5 or 6

longitudinal striae, the median one not stronger than the others.

Mandibles strongly and longitudinally striate, subopaque, with about

6 teeth. Frontal carinae divergent, ending at about the level of the

eyes and continued behind them as a stria, not forming the least trace

of ascrobe. Hyes not large, feebly convex, placed slightly behind the

middle. The scapes reach the posterior fifth of the head; 3rd joint

of flagellum a little wider than long, all the other joints longer than

wide. Head two-thirds wider than the thorax. Thoracic sutures

obsolete. Seen in profile, the dorsum of the thorax forms a continuous

and fairly low convexity from the anterior margin to the base of the

spines. Thorax slightly constricted between the meso- and epinotum ;

the promesonotum submarginate in front, the shoulders depressed and

subangular, as long as wide between the shoulders. Dorsum of

epinotum as long as the vertical declivity. Spines thin, acute,

8, 2 mm. Pale straw-yellow, the anterior third of the head a

little darker. Dull, the abdomen and legs slightly shining. The

fundamental sculpture on the head, thorax and petiole consists of a

fine reticulate puncturation, very superficial on the vertex and on the

nodes. In addition the head and pronotum are longitudinally striate,

the cheeks in front partly reticulate-rugose. Abdomen microscopi-

cally alutaceous and smooth. Pilosity erect, short and thick, present

only on the anterior margin of the clypeus, the 2nd node and on the

abdomen. A moderate pubescence on the legs and antennae.

Head quadrate, hardly longer than wide, the sides straight, the

posterior angles rounded. Median area of clypeus feebly carinate, its

anterior margin arcuate. The posterior lateral margins of the clypeus

are raised to form a transverse ridge (in the manner typical of the

genus). Mandibles finely striate, with a few large punctures behind

the masticatory margin, which is indistinctly dentate. The frontal

carinae are continued back as fine lines as far as the posterior third

of the head. Antennae 12-jointed, the 2nd—8th joints of the flagellum

much wider than long. LHyes large, convex, placed at the middle of

the sides. Head wider than the thorax. Promesonotum trapezoidal,

as wide in front as long, submarginate in front, the shoulders fairly

distinct and narrowly rounded, the promesonotal suture obsolete.

The thorax is fairly strongly constricted at the mesoepinotal suture,

which is distinct. Dorsum of epinotum two-thirds longer than wide,

widest in the middle, convex transversely, straight and oblique length-

wise, ending on each side in a blunt and low tubercle; the declivity

subvertical, half as long as the dorsum. Peduncle of the Ist joint of

the petiole as long as the node. The anterior face of the latter is

vertical, convex transversely and longer than the posterior face, which

1s convex from above to below; its dorsal face, seen from above, is .

nearly semi-elliptical, about as long as wide behind, the posterior

margin convex. Second node half as wide again as long, and half as

perhaps be transferred to the genus Tetramorvum. I have adopted

this suggestion, since it seems to me that the presence of the lateral

ridges of the clypeus and the not compressed 1st node preclude the

species from being attached to Rhoptromyrmez.

Whether Triglyphothriz be regarded as a subgenus of Tetramorvum

or not, the specific name is preoccupied in Triglyphothrixz Arnoldi, Forel,

and I have therefore altered the name of this species.

Dr. Santschi has expressed the opinion (on lit.) that this should be

latter species under a strong magnification reveals the presence of a

few bifid hairs on the abdomen. To my mind, the branching of the

and abdomen distinctly shining. Head longitudinally rugoso-striate

in the middle, reticulate at the sides and behind. Thorax and petiole

widely reticulate-rugose. Abdomen and legs smooth. Head rect-

angular, nearly one-sixth longer than wide, parallel-sided, the posterior

TRIGLYPHOTHRIX AUROPUNCTATUS, Forel.

Amongst the material collected by Haviland, in the Natal Mus.

collection, there are some specimens of this species, almost certainly

paratypes. An examination of these specimens indicates certain

discrepancies in Forel’s description.

274 Annals of the South African Museum.

Except on the scape of one specimen, I have failed to see any golden

reflection in the punctures, this, however, may be due to changes

brought about by their lengthy immersion in the alcohol. The upper

and lower grooves of the scrobe are divided by a raised line which is

slightly higher in front but not forming a triangular eminence in any

way. The sculpture of the 2nd node is a shallow and feeble punctura-

tion, not coarse as stated by Forel. There is no mesoepinotal suture,

its position being indicated only by a slight depression.

AUROPUNCTATUS, var. BULAWAYENSIS, Arnold.

This differs from the type of the species by its darker colour, which

is yellowish brown, by the sharper sculpture of the head and thorax,

and of the 2nd node which is as coarsely punctate as the Ist, and by

the coarse puncturation on the base of the abdomen. The size is also

somewhat greater, 3 mm.

half of the median area of the clypeus vertical, the posterior half

oblique or subhorizontal, the junction of the two planes marked by a

sharp transverse ruga, also bounded on each side by a longitudinal

ruga, strongly carinate in the middle. Seen from above, the carina

and the lateral rugae stand out prominently, making the anterior

margin of the upper portion of the clypeus appear almost tridentate.

A complete scrobe present, reaching back to the end of the third

quarter of the head. The scrobe is divided longitudinally by a sharp

line into two halves for the reception of the folded scape and flagellum ;

it is shining and feebly reticulate. Scapes as long as the scrobes ;

dark ochreous, the femora, except at their bases and apices, dark

brown. The sculpture is similar to that of the type of the species, but

less coarse, especially on the thorax and nodes, the rugosities being

closer together and less prominent. The chief differences, however,

between this form and the type lie in the pilosity and shape of the

thorax and nodes. The pilosity is much shorter and is entirely

decumbent, the shorter (trifid) hairs on the abdomen being depressed

into the little punctures, (somewhat like those of Tetramoriwm setuli-

ferum). The hairs on the legs and scapes, and sides of the 2nd node

are oblique, but there are no outstanding hairs anywhere. The

mesonotum is longer, being nearly half as long again as the pronotum,

(only as long in the type of the species), and the thorax is more con-

stricted at the mesoepinotal suture. The promesonotal suture is

faintly indicated, (entirely obsolete in the type of the species), and the

dorsum of the epinotum is steeper. The Ist node of the petiole, seen

from above, is semicircular, flatter transversely above, and barely one-

third wider than long, and with a straight posterior margin. The 2nd

node transversely oval, twice as wide as long, one-fourth wider than

This form presents a very different appearance from that of the type

which were somewhat intermediate in sculpture and -pilosity, pre-

cludes its separation as a distinct species.

little longer than wide, whereas in the type it is as long as wide. The

2nd node is two and three-quarter times wider than the Ist, (only

twice as wide in the type of the species).

These are only slight differences, but as an outa degree of difference

occurs in the 9, recently received from Zululand, the separation of the

Pretoria examples is justified.

The @ of the type of the species differs from that of the variety

(described on p. 356), as follows :—

2, (hitherto undescribed), 3-4 mm. The whole body, including the

legs and antennae, clothed with a sparing and fairly long, greyish

pubescence, oblique on the legs and antennae, decumbent elsewhere.

The vertex is exceedingly finely and sparsely punctured, the rest of

the body impunctate, and the shallow elliptical punctures which are

present in the variety are entirely absent. The posterior angles of

the head do not project so far back as in the variety, and the sides

above them are barely concave. Parapsidal sutures obsolete (very

distinct in the variety). The dorsum of the epinotum is more deeply

excavated. The 2nd node of the petiole is relatively narrower, with

more angular sides and a less concave anterior margin. Otherwise just

like the 9 of the variety.

3, (hitherto undescribed), 3-4 mm. Black; legs pale brown, tarsi,

antennae and mandibles dirty ochreous. Smooth, shining and

impunctate ; mandibles finely aciculate and dull. Pubescence as in

the 2. Head as long as wide across the eyes, trapezoidal, (excluding

the projecting portion of the clypeus), highest behind, the posterior

margin feebly convex, without projecting lateral angles. Anterior

margin of clypeus convex. Hyes convex, occupying a little less than

one-third of the sides, placed in front of the middle of the latter. The

scapes extend back as far as the anterior ocellus, Ist joint of flagellum

a little longer than wide, the 2nd joint as long as the scape, and com-

posed of 5 coalesced joints, since the whole antenna is 9-jointed ; in

some specimens the true 6th joint of the flagellum is faintly delimited

from the rest of the composite 2nd joint. Mesonotum convex trans-

versely in front, also above, shallowly impressed longitudinally in the

middle, a little wider than long. Scutellum fairly convex, wider at the

base than long. Dorsum of epinotum one-third wider at the base

than at the apex, a little longer than wide at the base, marginate, the

margins ending above the declivity in obtuse angles. Declivity

vertical, hardly more than half as long asthedorsum. The Ist node of

the petiole similar to that of the 9, seen from above, but less narrowed

in front, the dorsal surface more flattened and wider, not produced

below, a little longer than deep. Second node transversely elliptical,

not quite twice as wide as long, the anterior margin convex, the dorsal

surface flat or slightly concave, not convex as in the 2. Abdomen of

the usual form, without prominent lateral angles at the base. Legs

long and slender. Wings as in the &.

of such hairs. The enlarged ends of these hairs are subcircular, and

fully three times as large as those of C. Arnoldi, Forel. Closely and

very finely reticulate-punctate; the abdomen, which is slightly

shining, very superficially sculptured, the head and thorax above with

a fine longitudinal striation superimposed. Scrobes dull and reticulate-

punctate only. ~Head as wide as long, widest at the posterior fourth,

gradually narrowed anteriorly, half as wide again as the prothorax.

Mandibles aciculate, the masticatory margin finely denticulate.

Head shaped as in C. Arnoldi, but the posterior margin is distinctly

more convex, and the teeth on the upper edge of the clypeus are

blunter and shorter. The posterior part of the mesonotum is flat

from side to side, not convex as in Arnoldi, the posterior lateral angles

ending in small, rounded teeth, larger than those of Arnoldi, and

hidden by one of the spatulate hairs. The declivity and dorsum of the

epinotum lie almost in the same plane, whereas in Arnoldi the declivity

is steep. The dorsum is a little longer than wide, with a very minute

prominence behind on each side, (hardly a tooth, and much smaller

than in Arnoldi). The declivity is strongly marginate on each side.

Nodes as in Arnoldt.

Larger and darker than Arnoldi, and quite distinct from that

species by the form of the hairs, which are all strongly spatulate, the

widened terminal portion being round, not oblong as in Arnoldt.

Moreover, in the latter species the hairs are chiefly confined to the

abdomen. It differs from C. nummulitica, Santschi, by the sculpture,

especially of the epinotum, by the colour, and by the shorter peduncle

of the Ist node.

but a little more superficial. The epinotal spines brownish at their

apices. The Ist node of the petiole distinctly narrower than in the

type of the species and with longer teeth, one and a half times longer

than their basal width. The 2nd node is shorter, rather bluntly conical,

not with a flattened dorsal’ face as in the type of the species. Both

(as race of Havilandi, Forel, p. 378.)

Having recently seen the paratypes of Havilandi, Forel, (leg. Havi-

land, ex Natal Mus. coll.), it becomes apparent that Marleyi should

stand as a distinct species. In addition to the characters given on

p. 378, it also differs in the following features from Havilandi. The

colour is a pale raw umber, much darker than in Havilandi, which in

all the specimens I have seen is straw-yellow and not rusty yellowish-

red as stated in Forel’s description, (this, however, may be due to the

long immersion in alcohol, nearly twenty years, having leached the

colour out). The mesonotum is more convex lengthwise, and the

dorsum of the epinotum is a little wider than long. The dorsal face

of the 1st node is about one-quarter wider than long, (nearly twice as

wide as long in Havilandz) ; the dorsal face of the 2nd node is lenti-

cular, (semicircular in Haviland), and is only half as wide again as

long, and not quite twice as wide as the Ist.

I cannot agree with Dr. Santschi in granting these specimens a

distinct varietal name. The specimens which were sent to him were

compared with cotypes of Mayr, and, as I have pointed out before,

differ from them only to a very trivial extent. It is questionable

whether it is worth while to attach a distinct name to every petty

Since writing the first paragraph on p. 634, 1917, a long correspond-

3. South African Rhagionidae (Diptera) in the South African Museum.

By Professor M. BEzzt.

THE scarcity of the family Rhagionidae (=Leptidae), taken in its

narrowest sense (that is, after the exclusion of the Hilarimorphinae,

of the Xylophaginae, and of the Coenomyinae), is one of the most

striking features of the Ethiopian Dipterous Fauna. From more

than 300 species known from all parts of the world only the following

are recorded from the Ethiopian region :—

1. Leptynoma sericeum, Westwood, 1876, Damaraland.

2. Lampromyia argentata, Bigot, 1885, Cape.

3. Atherix binominata, Bequaert, 1921 (=longipes, Loew, 1863, nec

Bellardi, 1861), Bloemfontein.

4. Atherix braunst, Bequaert, 1921, Stellenbosch.

Atherix disciclara, Speiser, 1914, Cameroon.

Chrysopilus fulvidus, Bigot, 1891, Assinia.

Chrysopilus testaceus, Loew, 1858, Cafiraria.

Chrysopilus cricosphaerota, Speiser, 1914, Cameroon.

. Chrysopilus obscurupes, Speiser, 1923, Hast Central Africa.

Wory singular also is the complete absence of Khagio (= Leptis),

the typical genus of the family. On the other hand, the abundance

of the genus Atherixz (+ Atrichops), both in species and individuals,

is very characteristic. Out of 30 species of Rhagionidae in the South

African Museum, 20 (that is 66-6 per cent.) belong to that genus.

The importance of the family is great even from an economic point

of view, because it contains some blood-sucking kinds. One of these

is present in the collection, and is described here for the first time as

belonging to the Australian genus Athervmorpha. Others, like the

species of Atherix, are unique in habits, the females congregating in

dense clusters for oviposition, after which the young larvae feed

first on the cluster of dead bodies before reaching the water.

The African genera may be distinguished as follows :—

SuBFAMILY VERMILEONINAE.

Gen. LampromytaA, Macquart, 1835.

This genus is distinguished from the typical genus Vermileo, Mac-

quart in having a long proboscis and a non-pulvilliform empodium.

The genus Leptynoma, Westwood, 1876 (originally described from South

Africa as belonging to the Asilidae, like the European genus Apogon,

South African Rhagionidae (Diptera) in the South African Museum. 299

Perris=Vermileo), is certainly synonymous with it. The Mediter-

ranean species, like L. cylindrica and pallida, differ only in having

the face more produced below and forwards.

These flies are very interesting on account of the singular habits

of their larvae which live in the sand like those of the ant-lions, being,

however, very different in the shape of the body.

Of the forms described below, L. sericea and argentata are probably

one species, while brevirostris is very different from the others onaccount

of its strong and relatively short proboscis. They are as follows :—

1 (6) Proboscis thin and longer than one-half of the body; third antennal

joint short and with a thin arista; front tibiae with small and less

distinct terminal spur; thorax with a broad, blackish median stripe ;

abdomen entirely yellowish, clothed with silvery dust, and having a

deeply punctate area at the base of each segment.

2. (5) Upper branch of cubital fork S-shaped, curved above at end and set

obliquely or even almost perpendicularly ; thoracic median stripe deep

black.

3. (4) Third antennal joint blackish ; lateral dark stripes of back of mesonotum

broad; second longitudinal vein with a rounded bend, and not

appendiculate ; upper branch of cubital fork oblique, ending not much

before the wing-tip; fourth posterior cell open; first posterior cell

November 1917 (R. M. Lightfoot), which may be considered as

belonging to the present species. As Westwood’s original description

consists only of a few words a full description is necessary.

3. Length of body, 13mm. ; of wing, 10 mm. ; of proboscis, 6 mm.

Occiput black, densely clothed with opaque grey dust, with pale

yellowish hairs, and with a row of yellowish thin cilia at eyes-border,

these cilia becoming longer below. Frons parallel-sided, narrow,

being not broader than the distance between the basal ocelli; it is

black and quite bare, with a little dark grey dust in front; the

ocelli are of large size, placed on a prominent tubercle, which, however,

is not visible in profile, the frons being concave at the vertex. Hyes

bare, with the upper areolets not distinctly enlarged; they are of

large size, ovate, their vertical diameter being about twice as long as

the horizontal one; in profile they form almost the whole head, the

face only being prominent. Face in the middle twice as broad as the

frons, convex and rather prominent, but not with sockets, more

produced below than the lower corner of the eyes; it is densely

clothed with white dust and almost bare, having only a few thin

white hairs below on the sides. Antennae inserted a little above the

middle of the eyes, close to each other at base; they are carried

obliquely above and are about as long as the horizontal diameter of

the eyes; the two basal joints are yellowish, the first being twice as

long as the rather globular second, both with a few very short hairs

below, and bare above; third joint black, shortly conical, shorter

than the first joint; arista terminal, black, bare, distinctly shorter

than the whole antenna. Palpi blackish at end, yellowish at base,

curved upwards; proboscis black, reddish above at base, long and

thin, reaching nearly the hind border of the third abdominal segment.

Thorax short and convex, nearly bare, with very short pubescence in

front; on the back it is reddish, with a silky sheen; the middle

stripe is broad, black with reddish-brown sheen, complete in front

but abbreviated behind; the sides of this stripe are shiny white ;

above the notopleural line there is a broad reddish-brown stripe on

each side, interrupted at the suture. Humeral calli prominent,

reddish-sericeous, with a brown stripe below. Pleurae quite bare,

dark reddish, with sericeous sheen. Scutellum small, semicircular,

flat above, quite bare, reddish, with a broad blackish middle stripe

which does not reach the hind border. Mesophragma convex,

elongate, about four times as long as the thorax ; it is nearly parallel-

sided, being only a little narrowed towards the base, and rather flat ;

there are eight visible segments, the first and the last shorter, all the

others being of about the same length; each segment has a semi-

circular area at base with two rows of deep puncti; it is quite bare,

even at base, with a very short, thin, white pubescence at sides near

the end; entirely reddish, with no distinct dark markings, and

entirely clothed with dense silvery dust; venter entirely reddish,

unspotted, but without silvery dust. Male genitalia erect, reddish,

with short whitish pubescence. Legs of the two anterior pairs thin

and short, entirely yellowish, unspotted, with the tarsi blackened at

end; legs of hind pair much longer and thicker, reddish, with the

femora, tibiae, and tarsi fuscous at end, the praetarsi distinctly

swollen and as long as the other joints taken together; pubescence

very ‘short; the two terminal spurs of the four posterior tibiae are

long, strong, and yellowish ; claws black, with narrow reddish base.

linear alula, there is a prominent tooth. First vein ending beyond the

middle of the wing; praefurca long; second vein broadly rounded at

end; cubital fork proportionally short and broad, with the upper

branch rather S-shaped but less oblique, ending at a short distance from

the wing-tip ; discal cross-vein before the middle of the discoidal cell ;

first posterior cell broadly open at end; third posterior cell at end as

broad as the two preceding cells together ; fourth posterior cell and

anal cell narrowly open. Axillary lobe long and narrow. Costa

becoming thinner after the tip of the wing, but the ambient vein

complete. The wings are greyish hyaline, iridescent. There are

fuscous spots on the praefurca, below the stigma, forming a dark

band in the narrowed median part of the marginal cell; the last

portion of the second vein, after the bend, is edged with fuscous. The

veins are yellowish at base and darkened in the distal part.

2. Lampromyia appendiculata, sp. nov.

Closely allied to the preceding, and possibly only a variety of it,

but distinct in some important peculiarities of wing-venation.

and the palpi entirely yellowish ; the ground colour of the face below

the white dust is distinctly reddish ; the proboscis is a little longer.

Thorax and scutellum as in the preceding species, but there are no

dark lateral stripes above the notopleural line, only a narrow, reddish-

brown post-sutural stripe being present above the root of the wings.

Pleurae of a lighter reddish colour. Calypters and halteres as in the

preceding. Abdomen as in the preceding species, but more distinctly

narrowed towards the base; venter with a dark stripe in the middle

towards the end; male genitalia shorter, the upper lamella being

truncate at end. Legs as in the preceding species, but distinctly

lighter, even those of the hind pair being more yellowish than reddish.

Wing-pattern also as in the preceding species, but even the upper

branch of the cubital fork is edged with fuscous. Origin of the

second vein much nearer the discal cross-vein which is placed much

before the middle of the discoidal cell; terminal part of the second

vein bent at a right angle, and there strongly stumpy ; upper branch

of the cubital fork S-shaped and placed about perpendicularly, ending

much before the wing-tip ; first posterior cell as broadly open as the

second ; fourth posterior cell with a long stalk. All the veins of the

terminal part of the wing are distinctly thicker and blacker than in

the preceding species.

I have seen Bigot’s type, a male specimen from Hex River, 10th

January 1883. Head as in L. sericea, but the occiput and the frons

more densely white dusted; antennae with the third joint quite

reddish ; palpi of a paler reddish colour. The thorax is much paler,

with the broad middle stripe very light reddish brown. Abdomen

and legs as in L. serscea, but distinctly paler; the male genitalia are

apparently the same. Wings equal in shape and nervation, but

distinctly more yellowish and with paler veins; second longitudinal

vein similarly shaped; upper branch of cubital fork straighter and

placed more horizontally, thus ending nearer to the wing-tip; first

posterior cell narrower ; fourth posterior cell closed or even shortly

stalked ; anal cell more narrowly open. 7

4. Lampromyva brevirostris, sp. nov.

Very distinct from all the preceding forms on account of its short

and strong proboscis, of the long spur on the front tibiae (agreeing in

this character with the Mediterranean typical species), and of the

very different abdomen, which is moreover quite devoid of silvery

dust.

Type 3, from Zululand (M’fongosi), March 1917 (W. E. Jones) ;

the 2 type is without precise locality, but bears the following label:

“bred by Rev. N. Abraham from a larva kept for 2 years in

eaptivity, April 1920”; an additional g¢ from Hast London, 25/12/1923

(H. K. Munro).

39. Length of body, 11-12 mm. ; of wing, 9-10 mm. ; of proboscis,

about 2mm. Occiput black, dark grey dusted, with pale hairs near

the eyes-border, longer and more abundant underneath. Eyes more

rounded than in the preceding species, their horizontal diameter

being about as long as the vertical one. Frons black, grey dusted,

broader in the male than the distance between the basal ocelli; twice

as broad in the female. Face pale yellowish, white dusted, clothed

with scarce, thin, whitish pubescence ; in the male it 1s less produced

than in the other species. Antennae distinctly longer than in the

preceding species, chiefly because the third joint is elongate, being

longer than the first joint and longer than the thickened terminal

style; they are yellowish, more or less infuscated, with the third joint

fuscous at end. Palpi blackish. Proboscis short and strong, only

a little longer than the vertical diameter of the head; it is black

below and at end, red above near the base. Thorax reddish, a little

shiny, with bronze tomentum; on the back there are three black

stripes, the middle one dilated behind the suture and prolonged across

the middle of the scutellum; the lateral ones are distinct only

behind the suture, being represented in front of the suture only by a

short, blacker stripe. Pleurae shiny reddish, with broad black spots

on meso-, ptero-, and sterno-pleura ; they are quite bare, while the back

of the mesonotum bears a short darkish pubescence. Scutellum

small, rounded, flat above, reddish with a black median stripe and

with short dark pubescence; mesophragma shining reddish, grey

dusted above, with blackish lateral spots in the female. Calypters

bare, very narrow, conical, dirty yellowish. Halteres with yellowish

stalk and black knob. Abdomen distinctly stalked in the male, the

second, third, and fourth segments being cylindrical and narrower

than the others, while in the female this is not the case. Both sexes

of the segments, as in the Mediterranean species ; it is shiny reddish,

with black spots at the hind border of the segments and at the sides,

in the male the three last segments being entirely black above ; venter

reddish in both sexes ; pubescence short and blackish; male genitalia

black above and reddish below. Front coxae yellowish, unspotted ;

middle and hind coxae reddish and black spotted at end. The four

anterior legs are entirely pale yellowish, with only the last tarsal

joints black ; hind legs stronger and longer, with club-shaped femora

and tibiae, the femora yellowish, broadly black before the end, the

tibiae black, with narrowly whitish base; hind tarsi black; the

praetarsi with a whitish base; front tibiae with a strong and long

yellowish spur, like that of the Mediterranean species. Wings of

the usual shape, proportionately short and narrow; they are greyish

~ hyaline, iridescent, with irregular dark spots at the praefurca, at the

small cross-vein, in the middle of the marginal cell, and at the wing-

tip; some veins are moreover edged with fuscous. Second vein

regularly bent and not appendiculate (but in one specimen angular

and appendiculate) ; upper branch of cubital fork less sinuous, but

oblique and ending considerably before the wing-tip; small cross-

vein placed near the base of the discoidal cell; first posterior cell

broadening towards the end and there broader than the second,

fourth posterior cell narrowly open (9), or closed and stalked (2) ;

anal cell narrowly open or closed at the wing-border.

SuBFAMILY RHAGIONINAE.

Gen. AtricHoes, Verrall, 1909.

The species of the present genus are distinguished, in addition to

the characters given in the table, by the more elongate and more bare

body, and by the prevailing red colour of body, legs, and antennae.

Practically, the red antennae and red palpi are sufficient to separate

them from any South African species of Atherix or of Pachybates.

But in the Oriental Fauna there are species with black body, and

with black antennae and legs, showing, moreover, some scattered

hairs on the frons of the female. I have seen also a black, as yet un-

described, species from the Congo. This last species, like A. dis-

ciclara, Speiser, 1914, shows a deep longitudinal median furrow on

the fore part of the frons.

It is possible that the genus Suragina, Walker, 1860, is the same as

the present one ; and if so, its name must be used for the species now

South African Rhagionidae (Diptera) in the South African Museum. 305

included in Atrichops. They are, however, hardly separated from

Atherix.

The South African species known to me are as follows :—

1. (10) Back of mesonotum reddish, with or without a more or less broad black

stripe in the middle ; antennae entirely reddish.

2. (3) Back of mesonotum entirely reddish, without median stripe and without

presutural spots ; abdomen quite reddish, without black markings

reddish, with a white sheen on the basal joints; the third joint is

reniform, its vertical diameter being as long as the two basal joints

together ; first and second joint with some black hairs above ; arista

thin, blackish. Face very short, measuring only one-third of the

length of the frons; it is shiny yellowish, faintly grey dusted in the

white hairs; metapleura shining white with soft white hairs; meso-

phragma shining black in the middle. Scutellum reddish, shining,

with narrow black base, and with blackish hairs on disc and at border.

Squamulae pale yellowish, small, bare; halteres yellowish. Abdomen

entirely reddish, even on venter, with only a narrow black stripe in

the middle of the second and third segments ; the pubescence is pale

yellowish. Coxae and femora entirely yellowish, with a pale pubes-

cence; front and hind tibiae darkened with blackish pubescence ;

tarsi black, those of the front pair with tactile hairs below. Wings

proportionately long ; cubital fork very long; discoidal cell narrow,

with the small cross-vein on its basal third ; first, second, and third

posterior cell of about the same width at end, the fourth being distinctly

narrower; anal cell shortly stalked. The veins are blackish, with

yellowish base. The wing is yellowish hyaline, iridescent, with the

terminal half distinctly darker, the cells sometimes with paler centre ;

stigma dark yellowish ; a faint discoidal infuscation is present, but

not forming a definite discal band.

6. Atrichops monogramma var. agramma, nov.

Hixactly the same as the preceding species, but distinct by the

complete absence of any black marking on the back of the mesonotum

and on the abdomen.

South African Rhagionidae (Diptera) in the South African Museum. 307

Type 9, one specimen from Barberton, 5th October 1919 (H. K.

Munro). On the thorax there is no trace of median stripe and even

of presutural side-spots, the pleurae have the same white shining

vertical band, with a dark, not well-delimited spot on upper part of

the mesopleura. Abdomen without middle basal stripe and other

black markings. Legs the same, but with yellowish, less infuscated

hind tibiae; front tarsi with numerous tactile hairs below. Wings

similar, both in venation and colouring.

T. Atrichops inaequalis, sp. nov.

Perhaps only a variety of A. monogramma; but the male is very

different from both, and it is described here separately, being evidently

referable to one or to the other, more probably to the present species,

on account of its having been captured in the same locality and at the

same time.

Type 2 and type 3, a couple of specimens from Karkloof, Natal,

1915 (H. W. Bell-Marley).

®. Length of body, 10 mm.; of wing, 9 mm. Head and its

appendages exactly as described in A. monogramma ; the deep black

median band of the frons is broader, the fore half being shining white ;

the yellow face is densely clothed with white dust. Thorax, pleurae,

and scutellum exactly asin A. monogramma ; there is the same black-

ish, white-dusted spot on the upper part of the mesopleura, continued

above the notopleural line as a presutural spot. The abdomen

differs in having, besides the abbreviated basal black stripe, lateral

black spots on the second and third segment ; moreover, the two last

segments are broadly black at the sides; the venter is shining black,

with only the last segment reddish. Legs as in the preceding, but

with the tibiae much less infuscate, and with the praetarsi distinctly

pale at base. Wings as in preceding species, but with less infuscated

terminal half, and with no clear loop into the centre of the same

cells.

3. Length of body, 10-5mm.; of wing, 9 mm. Occiput entirely

white dusted, with a deep black stripe at upper eyes-border, and

with vertical black stripe from vertex to neck; hairs dark above,

longer and white below. Vertical triangle narrow, elongate, black,

grey before the ocelli, with some black hairs. Frontal triangle as

long as the middle distance between vertex and antennae, shining

white, quite bare. Eyes from a lateral view rather narrow, viewed

from the front broadly oval; they are in contact as long as one-third

308 Annals of the South African Museum.

of the distance between antennae and vertex, and have the anterior

middle areolets distinctly enlarged. Ground colour of face blackish,

but it is densely white dusted, like the cheeks, which are much

broader than in the female and likewise bare. Antennae, proboscis,

and palpi as described in the female. Back of mesonotum reddish,

rather shining, with long, erect, dark pubescence, and bristly hairs

at sides ; the median black stripe is as in the female, not overlapping

the dorsocentral lines and not edged with whitish stripes, or with

less distinct ones in the presutural part; the stripe is more linear,

beginning, without being attenuated, just above the neck and ending,

without being dilated, in front of the scutellum. The blackish, white-

dusted presutural spot is as in the female. The pleurae are different

in being completely blackish, white-dusted, only the propleura and

_ the pteropleura being reddish; mesophragma shining black in the

middle, yellowish on the sides. Scutellum shining reddish, narrowly

black at base, with long black hairs. Squamulae yellowish hyaline,

with yellow, bare margin; halteres yellowish. Abdomen shining

yellowish on the three basal segments, more reddish on the last four ;

first segment with black subquadrate spot in the middle ; second and

third segment with blackish spot in middle and with a deep black

stripe on each side; fourth to seventh segment with a darker black

middle spot and with deep black lateral stripes; hairs rather

long, whitish on the sides, dark in the middle; venter yellowish,

unspotted in the three basal segments, reddish with middle dark spots

on the others. Genitalia shining black above, reddish below, with

black hairs above and with yellowish ones below. All the coxae

yellowish, with pale hairs. Four anterior femora yellowish, with

whitish hairs; hind femora broadly black towards the middle and

there with dark hairs; front and middle tibiae darkened on terminal

half, those of the front pair more deeply so; hind tibiae long, thick,

almost entirely black and with black hairs; all the tarsi black, those

of the middle pair with paler base; hind praetarsi thick and longer

than the other joints taken together. Wings as described in the

female, but less infuscate on the terminal half; therefore the central

band below the stigma is more distinct, chiefly at the bases of the

discoidal and fourth posterior cells.

8. Atrichops bivittata, sp. nov.

Different from all the preceding species in the shape of the head, in

the broader middle stripe of the back of the mesonotum, and in the

South African Rhagionidae (Diptera) in the South African Museum. 309

absence of the dark presutural spot; it is, moreover, of distinctly

smaller size.

Type 9, a single specimen from Bulwer, Natal, September 1916

(Greene); one female from Marico, Transvaal, 1918, with more

yellowish face (H. K. Munro) ; moreover, in the Museum of Budapest

there is another female specimen from New Hannover, Natal, 1st

February 1913.

2. Length of body, 8-5 mm.; of wing, 8 mm. Occiput entirely

deep black, only dark grey dusted below at the sides; the hairs of

the upper part are dark yellowish brown, those of the lower part

are longer and whitish. Frons distinctly broader and shorter than in

the females of the preceding species; it is deep black on the basal

two-thirds and brownish red, white dusted on the apical third ;

there are a few short black hairs in the middle. HKyes more rounded,

with the vertical diameter about as long as the horizontal one. Face

shiny black, with faint white dust; side cheeks bare, white dusted,

twice as broad as in the females of the preceding species. Antennae,

palpi, and proboscis as in the preceding. Mesonotum reddish

yellow, but on the back it is black, opaque, the median stripe being

much dilated and extending beyond the dorsocentral lines, which are

marked with a narrow whitish stripe; moreover, the central part

of this broad black stripe is white dusted before the suture; the

hairs are blackish in the middle of the back, yellowish on the sides ;

there is no trace of the blackish presutural spot of the preceding

species. The pleurae are blackish, opaque, only the pro- and ptero-

pleura being yellowish; the dark parts are clothed with grey dust,

but the white shining vertical median band is wanting; the sparse

hairs are pale. Squamulae and halteres as in the preceding species.

Abdomen reddish, rather shining; the 3-4 basal segments with a

black triangular spot at base, the second and third segment, moreover,

with black lateral stripes; hairs pale yellowish at the sides, dark on

the back; venter entirely yellowish, unspotted, and with whitish

hairs. Legs with yellowish coxae and femora ; front tibiae and tarsi

black ; middle tibiae broadly yellowish and their praetarsi pale ;

hind tibiae yellowish at base, hind tarsi entirely black; front tarsi

elongate, with tactile hairs below. Wings as described in the preceding

species, but without terminal infuscation, even the median band

being very faintly indicated below the stigma and at the base of the

discoidal and fourth posterior cells.

Psyche, xxvili, 1921, p. 6 (Athertx)=longipes, Loew, Wien. Ent.

Monatschr., vu, 1863, p. 12 (Atherix), nec Bellardi, 1861.

Distinct from all the preceding species on account of the entirely

black thorax and of the different pattern of the abdomen; in the

form of head and in the smaller size it is more nearly allied to

A. bwittata than to any other.

Loew has described the male from Bloemfontein. I have seen one

female in the Museum of Budapest from New Hannover, Natal, 8th

February 1913.

®. Length of body, 8 mm.; of wing, 7-5 mm. Head and its

appendages as in the preceding ; occiput with whitish patches above

and at sides; the white dusted part of frons is one-third of the whole

length ; face black, with faint white dust ; cheeks rather broad, but

less than in bivittata; the second antennal joint blackish above, the

first only infuscated. Mesonotum entirely black, only the humeri

below, the notopleural suture, and a narrow stripe above the rest of

the wings being reddish ; middle part of back grey dusted before the

suture, but there are no distinct whitish dorsocentral stripes ; pleurae

whitish or grey dusted, but without vertical white shining band ;

hairs dark. Scutellum shining reddish, with black base ; hairs pale ;

halteres yellowish. Abdomen reddish; first and second segments

with a black median spot, the second, moreover, with black lateral

stripes; third, fourth, and fifth segments with broad black basal

bands; seventh segment with deep-black sides; venter yellowish,

unspotted ; the hairs are dark on the black parts and pale on the

reddish parts. Legs with yellowish coxae and femora ; front and hind

tibiae and all the tarsi black; middle tibiae dark yellowish; front

tarsi with tactile hairs below. Wings as in the preceding species,

distinctly but faintly infuscate on terminal half; the median dark

band is less distinct.

Gen. ATHERIX, Meigen, 1803.

In determining the species of the present genus one must take into

consideration the great difference between the sexes of the same

species. The South African species are not unlike the European ones :

the first resembles A. ibis; the second in the female likewise re-

sembles A. 2b1s, while in the male it is more like A. marginata; the

third resembles A. marginata in both sexes ; the fourth is an aberrant

South African Rhagionidae (Diptera) in the South African Museum. 311

form, which makes a passage to the following new genus. The third

species is noteworthy by the widely separated eyes of the male ;

the second by the male being much darker than the female, precisely

the contrary of what is to be seen in A. 2bis, in which the female is

darker than the male.

The species, which seem to be mostly mountain-dwellers, yon be

distinguished as follows :—

1. (6) Both branches of cubital fork of nearly equal length, ending symmetrically

at wing-tip ; discoidal cell sending three complete veinlets to hind margin

of wing; pterostigma blackish ; hind tibiae with well developed spurs ;

abdomen opaque.

2. (5) Wings with a rich design, consisting of fuscous and hyaline spots ; abdomen

with distinct yellow parts, at least on venter in the male ; legs in part or

entirely yellow ; eyes of male very close.

3. (4) Wings brown, with three irregular bands of whitish hyaline spots ; legs of

male yellow ; abdomen of male yellow, with basal black bands on all the

segments . : peringueyt, sp. Nov.

4. (3) Wings slightly intdenter in a shor cee median band surrounded by

irregular hyaline spots; legs and abdomen of male in greatest part

black ; legs and abdomen of female in greatest part yellow.

barnardi, sp. nov.

5. (2) Wings almost entirely hyaline, with a hardly distinct dark sub-stigmatical

band, which is not surrounded by hyaline spots ; abdomen in both sexes

entirely black, even on venter; legs black; eyes of male as broadly

distant as those of female . : ; androgynda, sp. Nov.

6. (1) Upper branch of cubital fork shorter eA the lower one and ending much

before the wing-tip; lower veinlet from the discoidal cell reduced to a

short stump ; pterostigma very faintly infuscate ; hind tibiae with small

spur; abdomen shining . : ; : . incompleta, sp. nov.

10. Atherix peringueyt, sp. nov.

An elegant species, the brightest coloured of all those here described,

recalling the Huropean A. 2bis, but with different wing and abdominal

pattern.

Type 4, a single specimen from Stellenbosch, November 1887,

collected by Dr. L. Peringuey, in whose honour this fine insect is

named.

3S. Length of body, 12-5 mm.; of wing, 12 mm.; of wing-spread,

26 mm. Occiput densely clothed with opaque grey dust, with short

darkish hairs above and with longer and abundant whitish ones

below. Frons black, with opaque blackish-grey dust, and with long

black erect hairs throughout the whole length; it is narrow, being

about in the narrowest part as broad as the distance between the two

312 Annals of the South African Museum.

basal ocelli, being a trifle broader at root of antennae. Hyes depressed,

narrow in lateral view, but nearly circular in front view; they are

bare, with equally small areolets. Antennae inserted very low and

broadly separated at base; they are short and small, entirely black,

with all the three joints of about the same length; the third joint is

rounded, with a basal arista; basal joints with black, bristly hairs

above. Face very short and broad, densely grey dusted, bare ;

side cheeks as broad as the antennae, grey, clothed with long darkish

hairs. Palpi and proboscis black, with long black hairs; the latter

is thick, about as long as the former or only a little longer. Back of

mesonotum black, opaque, clothed with long, erect, dark pubescence ;

on the sides, above the notopleural line, there is a broad grey stripe,

extending from the humeri to the sides of scutellum; if the disc is

striped or not, it is impossible to say, owing to the bad preservation

of the single type. Pleurae densely grey dusted, opaque, with paler

pubescence. Scutellum black, grey dusted on the disc, a little

shining, with long pale hairs. Squamulae whitish, with yellow border

which is pale haired; halteres with yellowish stalk and blackish

knob. Abdomen conical, broad at base; first segment deep black, with

reddish sides and a broad grey hind border ; second, third, and fourth

and fifth segments reddish yellow, with a broad deep-black basal

band, which has in the middle a black prolongation reaching nearly

to the hind border, which is grey dusted; the two last segments

are reddish, with a black middle spot; genitalia reddish; hairs

pale on reddish parts, black on dark parts; venter entirely yellowish

grey, with a whitish hind border to the sternites and with rather

long erect white hairs. Legs entirely yellowish, with infuscated last

tarsal joints ; coxae black, grey dusted; hairs long and pale; front

tarsi elongated, longer than their tibiae, with no distinct tactile

hairs. Wings with the same venation as in A. 7bzs, but with the cubital

fork longer, its base being about above the middle of the discoidal

cell. The wings are entirely brown, and there is no trace of the

yellowish spot of A. ibis at the end of submarginal cell, just beyond

the stigmatical spot ; the three oblique bands of whitish hyaline spots

are aS follows: the first goes from the base of the marginal cell

across the ends of second basal and anal cells to the base of the axillary

lobe, diluted at ending; the second goes from the middle of the

first submarginal cell across the base of the second submarginal,

base of first posterior, middle of discoidal, and base of fourth posterior

cell, to the middle of the fifth posterior cell; the third is the shortest

of all and consists of four spots, two before the end of second sub-

South African Rhagiomdae (Diptera) in the South African Museum. 313

marginal and first posterior cells and two in the middle of the third

and fourth posterior cells, one in anal cell.

ll. Atheriz barnardt, sp. nov.

Distinct from the preceding by the much blacker male, and in both

sexes by the much more reduced wing-pattern ; the male recalls the

Kuropean A. marginata, while the female is very different.

Type 3, type 9, and some additional specimens from Oudebosch,

Caledon Div., 1500 ft., January 1919; another male from Zonder Ende

Peak, 3600 ft., Cape, January 1919, all collected by K. H. Barnard,

in whose honour the species is named.

Owing to the great differences, the sexes are described separately.

3. Length of body, 7 mm.; of wing, 5-5 mm.; the specimen

from Zonder Ende Peak measures 8 mm. in body and 6:5 in wing.

The appendages and vestiture of the head are as described in the

preceding species; but the eyes are distinctly more approximate,

their distance at the narrowest point being equal to one ocellus ;

the frons is deep black, with a grey middle stripe between the antennae,

prolonged on the middle of the frontal triangle. Thorax entirely

opaque black, with dark pubescence; on the back are two equal,

complete, narrow, whitish stripes along the dorsocentral lines ; pleurae

grey dusted, with sparse whitish hairs. Scutellum black, rather

shining, with a broad red hind border, which is less distinct on the

Zonder Ende Peak specimen; hairs erect, pale. Squamulae and

halteres as in preceding. Abdomen narrower at base, cylindro-

conical; clothed with long, erect, pale hairs. First segment grey,

with black base; second, third, fourth, and fifth segments black,

with a narrow, yellowish, grey-dusted hind border ; sixth and seventh

segments likewise, but less distinctly so; genitalia black. Venter

black, with broad yellowish hind borders of all the segments; hairs

whitish. Legs black, with the four anterior femora and tibiae more

or less distinctly yellowish, while the hind femora are yellowish at

both ends; front tarsi elongate, with more distinct tactile hairs.

Wings with nervation and pattern about the same as in A. marginata

(Verrall, British Fles, 1909, fig. 192, p. 290), but even in this case the

cubital fork is longer.

2 Length of body, 5:-5-6-5 mm.; of wing, 5-5-5 mm. Head and

its appendages as described in the male; the eyes are smaller, their

vertical diameter being longer than the horizontal one; the frons is

broad, about one-fourth of the head, with parallel sides, clothed on

314 Annals of the South African Museum.

its whole length with long, erect, black hairs; it is of a deep black

colour, with a broad grey stripe along the middle; ocellar spot black ;

vertex grey. Back of mesonotum blackish grey, with two broad

whitish stripes united together in front of the scutellum; humeri

yellowish ; a broad grey stripe above the notopleural suture. Pleurae

yellowish, whitish dusted, more or less broadly blackish above and

- below. Scutellum reddish, with a narrow black base. MHalteres

yellowish, with the knob black at end. Abdomen broad, parallel-

sided, flat, obtuse at end, with scattered and soft whitish hairs; it

is entirely reddish yellow, even on venter ; first segment with a small

black central spot; second, third, fourth, and fifth segments with

a broad, equal, black, basal band, which does not reach the sides,

these, however, with a narrow black stripe on their deflexed borders ;

sixth and seventh segments with a much less distinct pattern ; more-

over, the segments from the second to the fifth have each a broad,

white shining hind border. Legs with yellow coxae and femora,

front and hind tibiae black, middle tibiae yellowish; all the tarsi

black, those of the front pair with long tactile hairs below. Wings

as in the male, with well-developed pattern.

12. Atherix androgyna, sp. nov.

Allied to the preceding, but with less patterned wings, broadly

separated eyes in the male, and female much darker.

Type dg, a single specimen from Gt. Winterhoek, Tulbagh, 4500 ft.,

November 1916 (R. M. Lightfoot); type 9, and some additional

specimens of same sex from French Hoek, 2500-3600 ft., December

1916 (K. H. Barnard).

3. Length of body, 6 mm.; of wing, 5:55 mm. Head and its

appendages as described for the male of the preceding species, but

the eyes are about as widely separated as in the female of the preceding

species; the parallel-sided frons is as broad as one-quarter of head,

opaque black, with a narrow greyish median stripe on the anterior

half, visible only in some lights. Thorax, pleurae, and scutellum

entirely black; but the type being in bad condition it is impossible

to see if there is a pattern or not. Halteres black, with yellowish

stalk. Abdomen shaped as in the male of the preceding species,

entirely black, even on venter; second, third, fourth, and fifth

segments each with a rather broad whitish hind border; genitalia

entirely black and black haired; they are apparently shaped as in the

preceding species ; hairs of back and venter short and scarce, mostly

black, pale only at sides near the base. Coxae and legs entirely

South African Rhagtonidae (Diptera) in the South African Museum. 315

black, even those of the middle pair; anterior tarsi without distinct

tactile hairs below; hind tibiae with short spurs, only the internal

one being rather developed. Wing-nervation as in the preceding

species. The wing-pattern is very reduced, consisting only of a black,

elongate stigmatical spot, and below this of an uncertain dark median

band extended to the base of the discoidal and fourth posterior cell ;

there is also an elongate dark spot in the middle of the first basal

cell; but the usual whitish hyaline patches of the preceding species

are not distinguished, and therefore the middle dark band is less

striking.

2. Length of body, 5-5-6 mm.; of wing, 5-5-5 mm. Head and

its appendages as in the male, but the frons distinctly broader, being

as broad as the third of head, and thus distinctly broader than in

the female of A. barnardi; it is black, grey dusted, with a distinct

longitudinal median furrow, which is not present in the male. Thorax

black, with reddish-brown humeri and grey-dusted pleurae ; on the

back there are two less distinct, narrow, distant, greyish stripes ;

the sparse pubescence is blackish on the back, whitish on the pleurae ;

scutellum and halteres as in the male. Abdomen shaped as in the

female of A. barnardt, entirely opaque black, even on venter; all the

segments have a greyish hind border, which is broader on the inter-

mediate segments and is present even on venter; the hairs are very

short and scarce, even at the sides, where they are pale. Legs en-

tirely black, brownish in immature specimens; front tarsi with a

few tactile hairs below ; hind tibiae with small spurs, like those of the

male. Wings as described for the male, but with even a fainter

pattern, being sometimes hyaline with a dark stigmatical spot and

with a less distinct trace of the middle band.

13. Atheria incompleta, sp. nov.

Very different from all the other species here described on account

of its shining abdomen, of its very peculiar wing-venation, and of the

very minute spurs of the hind tibiae.

Type 9, a single badly preserved specimen from Paarl, Cape,

October 1919 (Rev. G. Hawke).

The position of this strange insect is doubtful. It cannot be

placed in Symphoromyra, notwithstanding the indistinct spurs of

hind tibiae, owing to the closed anal cell. The possibility is not

excluded that it may be the female of a species of the new genus

following, or even the unknown female of the type-species itself ;

but I refrain to accept this last opinion on account of the very different

316 Annals of the South African Museum.

form of the cubital fork, which is different from that of all the other

species here described.

2. Length of body, 5 mm.; of wing, 5-5 mm. Head and its

appendages as in the preceding female; the frons is of the same

width, as broad as one-third of head, has a longitudinal middle

furrow, and is opaque black, and seemingly pale dusted ; the palpi

are shorter and more obtuse than in the preceding. Thorax dis-

tinctly broader than in all the preceding species, being rather sub-

quadrate; it is entirely dull black on the back, with reddish-brown

humeral and postalar calli, and apparently without any pattern ;

the pubescence is long, soft, dense, erect, dark in colour, and almost

bristly on the notopleural depression before the suture; the pleurae

are dark grey dusted and clothed with long whitish hairs on meso-

and hypo-pleura. Scutellum broader than long, black, rather shiny,

clothed with hairs like those of back. MHalteres black, with yellowish

stalk. Abdomen broader than in all the preceding females, being

as broad as the thorax; it is shiny black, with a narrow, reddish-

brown hind border to the segments, but without any other distinct

pattern ; the hairs are long and soft, pale yellowish, chiefly at sides ;

venter entirely black. Legs short and thicker than in all the preced-

ing species ; they are partly broken off in the case of the type, but

the coxae are black, the hind and middle femora are black, with

dark reddish base; hind tibiae and hind tarsi black, the former

with hardly visible spurs. Wings distinctly longer and broader than

in all the preceding species; they are greyish hyaline and practically

unspotted, even the stigmatical spot being faintly indicated. The

venation is very peculiar, chiefly on account of the cubital fork,

which has the upper branch short and ending before the wing-tip,

while the lower branch is longer and ends precisely at the wing-tip

(in the other species both the branches are equal in length and end

symmetrically at both sides of wing-tip). The discoidal cell is acute

outwardly, both its superior veinlets issuing practically from the same

point and the third inferior veinlet being reduced to a very short

stump; there are therefore only four posterior cells, the second of

which is of triangular shape. Anal cell regularly closed and provided

with a short stalk.

PACHYBATES, gen. nov.

The present new genus shows all the characters of Atheriz s. str.,

with the following differences: 1. The body is shorter, broader, and

more densely hairy; 2. the wings are long and broad, longer than

South African Rhagionsdae (Diptera) in the South African Museum. 317

the body, and quite unspotted; 3. the eyes of the male are widely

separated; 4. the abdomen of the male is short, with only five

visible segments; 5. the genitalia of the male are of greater size and

very differently shaped, being, moreover, pendulous instead of erect ;

6. the legs are very thickened, all the femora and the hind coxae

being greatly swollen in the male, in which the praetarsi of the hind

pair bears moreover a strong terminal, spur-like expansion; 7. the

spurs of hind tibiae are very small. Some of these characters are

strictly sexual, but the general appearance of the fly is very

peculiar. The wing-venation is exactly as in Atheriz, the cubital

fork being equally branched, both branches ending symmetrically

with the wing-tip.

Type, Atherix braunsi, Bequaert, 1921.

14. Pachybates braunsi, Bequaert.

Psyche, xxviii, 1921, p. 1, fig. (Atheriz.)

A very characteristic fly, looking not unlike some species of Scato-

phaga or of Brachyopa, with orange and softly haired abdomen, and

with whitish halteres.

I have seen a male specimen of the typical series, caught at Stellen-

bosch (1st November 1915) by Dr. H. Brauns, and sent me by this

collector. JI have nothing to add to the excellent and long description

of Dr. J. Bequaert. All the coxae are distinctly swollen, chiefly those

of the hind pair; the spurs of the hind tibiae are much smaller than in

all the other species, excepting A. incompleta.

The female is not yet described, but is recorded by Dr. Brauns as

a much darker insect, agreeing in this with the above described

A. wncompleta. |

Gen. ATHERIMORPHA, White.

Proc. R. Soc. of Tasmania, 1914, p. 41.

I place here provisionally in this Australian genus an interesting

fly which agrees with it in the main characters, but shows some

peculiarities. The possibility is not excluded that this fly may be

a blood-sucking one, like some species of Symphoromyia or of Spani-

opsis, which have, however, the hind tibiae with only one spur or

without any distinct spurs at all. The generic characters of the South

African species are as follows: Hyes widely separated in both the

sexes, not bisected. Face broad and short, flat, not socketed.

Antennae inserted very low, with the third joint gradually drawn out

into a terminal, long, and thick style, which is longer in the male than in

318 Annals of the South African Museum.

the female. Proboscis rather projecting, strong, as long as the palpi.

Back of mesonotum and scutellum beset with long, erect, bristle-like

hairs which at sides before the sutures are almost like true bristles ;

pleurae nearly bare, with a few thin hairs on metapleura. Abdomen

long, narrowly cylindrical, thiny pilose. Legs with rather thickened

femora in the male; tibiae beset with distinct spicules, the anterior

ones without spurs, while those of the two last pairs have two very

robust ones ; front tarsi devoid of tactile hairs below. Wings broad,

with rounded alula; second vein long, longer than the elongated

cubital fork; discoidal cell short, equal to the second and third

posterior cells, with three complete veinlets issuing from its external

border ; five posterior cells, all broadly open outwardly, the fifth

being at base not in contact with the discoidal cell; anal cell closed

at wing-border, or narrowly open.

15. Atherimorpha albipennis, sp. nov.

A black, densely grey-dusted fly, with conspicuously white-haired

abdomen and white wings.

Type 3 and 9, a single couple of specimens from Hottentots Holland

Mts., 4000 ft., Caledon, Cape, 1916 (K. H. Barnard). I am not sure

about the sexes, but I have considered as the male the specimen with

longer antennae and with closed anal cell.

39. Length of body and wings, 5-6-5 mm. Head entirely black ;

occiput densely covered with light grey dust, deeply concave in the

middle and beset at sides with long, black, bristle-like hairs disposed

in two to three irregular rows; near the eyes and below there are white

hairs. Frons of about the same breadth in both sexes, only a little

longer than broad ; it is clothed with dense, dark grey dust and with

scattered, erect, bristly, black hairs; ocellar tubercle of great size,

rounded, prominent, with erect black hairs; above each antenna

there is a prominent transverse keel. Face bare, grey dusted in the

dust; on the back there are three dark stripes, that of the middle

narrower than the others; the pleurae are lighter grey dusted, with

several, irregular, darker spots. The hairs of the back are long,

erect, black, bristle-like; they are disposed in one row, both the

acrostical and the dorsocentral and the lighter lines between them

being quite bare; beyond the dorsocentral lines the sides of the back

are clothed with bristly hairs, with several true bristles above the

notopleural line, before the suture; the pleurae are bare, with only

a few thin hairs on the metapleura. Scutellum like the back of

mesonotum, with erect, bristly hairs at hind border. Squamulae

white and white-fringed ; halteres very long, whitish, with a partly

darkened knob. Abdomen elongate, cylindro-conical, with seven

visible segments in the male and eight in the female; it is black,

densely clothed with a light grey dust above and with a darker

grey dust on venter; it is equally clothed with thin, dense, white

hairs. Male genitalia small, with a grey lamella below and with

reddish appendages above. Legs with black, grey-dusted coxae,

dark reddish femora and tibiae, and the tarsi darkened towards the

end; all the femora are distinctly thickened in the male; the tibiae

have distinct dark spicules, disposed in three regular rows; the

femora have very sparse shiny pale hairs; the last joints of the front

tarsi are rather thick ; the pulvilli and the broad, pad-like empodium

are dirty yellowish. Wings very broad, rounded outwardly, entirely

whitish, with black costa and dark veins which are yellowish at base ;

stigmatical spot elongate, not much infuscate, occupying the middle

of the marginal cell, between the end of the praefurca and the end of

the first longitudinal vein. Second vein long, a little wavy ; cubital

fork long and narrow, longer than its stalk; small cross-vein near

the base of the short and small discoidal cell; second posterior cell

broad at base; ambient vein complete; axillary lobe rounded like

the alula, the former being three times as long as the latter.

SuBFAMILY CHRYSOPILINAE.

Gen. CHRYSOPILUS, Macquart, 1826.

Dr. Speiser has given in 1914 (Deutsch. Entom. Zeitschr., p. 5) a

key to the three known Ethiopian species of the present genus. From

South Africa I have seen the following two :—

1. (2) Back of mesonotum yellowish ; pterostigma rounded; second posterior

cell with a long and acute base . : testaceus, Loew.

2. (1) Back of mesonotum blackish; pterostigma elongate; base of second

posterior cell short . : : : : 3 tuckert, sp. nov.

VOL. AXIII, PART 2. 21

320 Annals of the South African Museum.

16. Chrysopilus testaceus, Loew, 1858.

Distinct by its much lighter coloration, and by the peculiar wings.

Originally described from Cafiraria, but never found subsequently.

I have seen specimens of both sexes from Barberton, Transvaal,

April (H. K. Munro).

To the original description may be added: pterostigma rounded,

being only a little longer than broad ; it is sharply marked, ending

before the end of the marginal cell, which has therefore a hyaline

spot at end, and beginning abruptly inwardly. The second posterior

cell is very acute at base, its inner point being only a little shorter

than the length of the terminal cross-vein of the discoidal cell.

17. Chrysopilus tuckert, sp. nov.

Closely allied to the preceding and perhaps only a dark form of it,

but distinct by its greater size and by the different wings.

Type 3, and an additional specimen of the same sex from Humans-

dorp, Coldstream, February 1921 (R. Tucker) ; named in honour of

the collector.

3. Length of body, 8 mm.; of wing, 7-5 mm. Eyes as in the

preceding species, sharply bisected, and in contact in a line which is

not longer than the prominent ocellar tubercle. Occiput entirely

black, dark grey dusted, like the narrow and elongate frontal triangle ;

ocellar tubercle black and bare. Side cheeks black, grey dusted,

bare; facial socket dark yellowish. Antennae with the two basal

joints yellowish, the third and the arista blackish. Palpi yellowish,

with white hairs; proboscis yellow, with pale yellowish flaps. The

hairs of the lower part of head are whitish. Back of mesonotum

blackish, with yellowish humeral and postalar calli; and with yellow-

ish notopleural line; it seems that there is no trace of the golden

tomentum found in the preceding species; pleurae yellowish grey,

with darker parts; there are no hairs; scutellum yellowish, denuded

in the specimens before me. Squamulae hyaline, with darker border ;

halteres pale yellowish, with darkened knob. Abdomen blackish,

with yellowish basal segment and with a yellowish band at the hind

border of the segments from the second to the fifth ; last segments

and genitalia quite black. All the hairs whitish; venter entirely

yellowish. Coxae and legs pale yellowish, the tarsi darkened at end.

Wings iridescent, hyaline, with a faint darkish tint ; stigmatical spot

brown, elongate, fillmg up the whole end of the marginal cell, which

lacks the conspicuous hyaline terminal spot of the preceding ; more-

over, there is inwardly a yellowish shade extending to the middle of

the marginal cell. Veins blackish. Venation as in the preceding,

with the difference that the acute base of the second posterior cell is

shorter, being shorter than one-half of the terminal cross-vein of the

discoidal cell; this last cell is therefore narrower and more regularly

rectangular than in the preceding species; the basal cross-vein of

the second posterior cell is less than one-half the length of the terminal

cross-vein of the discoidal cell, while in C. testaceus these two cross-

veins are of about the same length.

SuBFAMILY ARTHROTELINAEH, nov.

This new subfamily is very like the Nearctic Arthroceratinae, showing

also an antennal flagellum consisting of eight distinct joints, and

the front tibiae without spurs, but it is distinguished by the elongate

proboscis, a very rare character among the Rhagionidae. The

bisected eyes of the male are as in the Chrysopilinae, from which the

new subfamily is distinguished also by having two spurs on the

hind tibiae.

ARTHROTELES, gen. nov.

This new genus is very like a Symphoromyia or a Chrysopilus in

general appearance, but is at once distinguished by the annulated

flagellum of the antennae. The form of the face is as in the North

American genus Arthroceras, Williston, or in the related genus

Misgomyia, Coquillett, 1908, but the long proboscis is very peculiar.

In the Australian genus Atherwmorpha, White, according to Mr.

andy (rap ands iroc. lev.) soc. ok, Vasmania, “1919, p.) 120,

pl. xxvu, fig. 2), the antennal style shows some annulations at the

base; but this is not the case with the South African species

A. albipennis, which I have described above.

Head in front view broader than high, with the occiput concave

in the middle and rather prominent at the sides. Ocellar tubercle

prominent, with three ocelli of rather large size. yes bare, in the

male meeting in a long line, bisected, the smaller areolets being

limited to the lower third. Frontal triangle very small, much smaller

than the ocellar tubercle and rather depressed. Face transverse,

much broader than high ; it is divided into three parts by two deep,

diverging furrows running from the base of antennae to the oral

margin ; the middle part is socketed and bare; the side cheeks are

also bare, but have very long hairs below. The antennae are inserted

below the middle of the eyes and are longer than the antero-posterior

322 Annals of the South African Museum.

diameter of head, being carried horizontally ; they resemble very

much those of Arthroceras (see Williston, Man. N.A. Dipt., third edit.,

p. 161, fig. 19); the two basal joints are of about the same length,

the second, however, being more swollen and globular, and both are

clothed with rather long hairs; the third joint is smaller but longer

than the second, and bears a seven-annulated style, thus resulting

in a flagellum of eight quite distinct joints, which, as a whole, is about

four times longer than the two basal joints together ; the last sezment

of the flagellum is longer than any other and is about as long as the

first (or true third antennal joint). Proboscis slender and acute,

directed obliquely forwards, as long as head and thorax together :

palpi long and verv hairy, with the last joint greatly swollen and

curved ; they are about as long as the antennae, and much shorter

than the proboscis. Thorax rounded, with the back of the meso-

notum convex, clothed with long hairs, but without bristles or bristly

hairs; pleurae almost bare. Scutellum with long hairs, but without

bristly ones. Abdomen conical, with seven visible segments, the

first and the second terminal segments being much shorter than each

of the others; male genitalia erect. Legs normal; tibiae with three

rows of less-developed spicules; front tibiae without spurs; middle

and hind tibiae each with two strong spurs; empodium pulvilliform,

as broad as the pulvili. Wings with about the same venation as in

Arthroceras (see Williston, Manual, p. 161, fig. 18). There are five

posterior cells, all broadly open, the first, second, third, and fourth

of about the same breadth at end, the fifth much broader, being about

as broad as the third and the fourth together. Cubital fork narrow

and long, longer than its own stalk ; its lower branch ends below the

wing-tip. Small cross-vein placed very near the base of the discoidal

cell, which is parallel-sided, acute at base, and obtuse at end; anal

cell closed at wing-border; axillary lobe broad, of nearly triangular

shape; alula rounded and fringed with long hairs, like the axillary lobe.

Type, the following new species.

18. Arthroteles bombyluformis, sp. nov.

An elongate, dark fly, looking very much like some species of

Bombylidae, but at once distinguished by the annulated flagellum

of antennae, by the three broad, pad-like pulvilli, and by the five

posterior cells of wings.

Type 3, and an additional specimen of the same sex from the

Cedarbergen, Clanwilliam Div., 4000-5000 ft., September 1923

(K. H. Barnard).

3. Length of body, 5-5-6 mm.; of wing, 4-8-5 mm. ; of proboscis,

about 2 mm. Head entirely black, with dark grey dust on the

occiput and with lighter grey dust on the face. The hairs of the

occipital fringe and those of the ocellar tubercle are long and black ;

the hairs of the underside of head are very long, dense, soft, and

white. Antennae quite black, with black hairs on the basal joints.

Palpi and proboscis black, the former with long black hairs, which are

particularly long and dense on the swollen terminal joint, forming

dense tufts inferiorly. Thorax opaque black, clothed with dark grey

dust ; in the middle of back there are three black stripes, the middle

one distinctly narrower, and all ending before reaching the scutellum ;

the hairs of the back are very long and black, like those of scutellum ;

pleurae with a few scattered black hairs, and with a fan-like row of

white hairs on metapleura. Halteres black, with pale yellowish

stalk; squamulae whitish, with whitish hairs. Scutellum and

mesophragma black, dark grey dusted. Abdomen entirely opaque

black, with dark grey dust which is lighter on venter and along the

hind border of the middle segments; it is clothed with rather long

white hairs ; genitalia black, pale hairy. Legs entirely black, opaque ;

coxae and femora with long whitish hairs ; spurs and spicules blackish ;

the three pulvilli whitish. Wings greyish hyaline, a little darker

along the fore border towards the base ; stigmatical spot narrow and

long, brownish, extending from the base of the praefurca to the end

of the submarginal cell. Veins black and rather thick, only the

extreme base a little yellowish.

5. The Oedemeridae of South Africa with Notes on some other African

Oedemeridae (Coleoptera).—By K. G. Buatr, B.Sc., F.H.S.

(Published by permission of the Trustees of the British Museum.)

THE family Oedemeridae seems to be but poorly represented in the

African fauna ; not only is the number of species small but the number

of individuals is also scanty. It is true that Fairmaire has described

about fifteen species from Madagascar, while Pic (1922) has recently

named several more from Madagascar and from tropical Africa; but

from South Africa one only, Ananca hottentota, Fairm., has been hitherto

described. Others have existed for many years both in the British

Museum and in the South African Museum, and it is at the request

of the late Dr. L. Péringuey that the present attempt to work out this

South African material is undertaken.

Of the forms now dealt with two only, one of which is an almost

cosmopolitan species, can claim to have anything like a general

distribution in South Africa ; of the remainder there exists usually but

a single record, though in many cases two or more individuals are noted

of each. Though not included in the fauna of South Africa proper,

which for convenience sake may be taken as south of the Zambesi,

certain species from Nyasaland, which bear a close affinity with

those of Mashonaland, are included; I take the opportunity to deal

also with two further hitherto undescribed forms, one from Uganda

and one from West Africa.

The classification adopted is that given by Seidlitz (1899).

(sub. fam. Oedemerinae) Asclerosibutia Pic

Nacerda melanura, L.

Linnaeus, Syst. Nat., 1758, vol. i, p. 403 (Cantharis).

Ruto-fulvous, with the tips of the elytra, the legs and the underside

blackish.

The head is withdrawn not quite as far as the eyes in the prothorax ;

the eyes moderately deeply emarginate ; the antennae inserted not

quite in the emargination, the mandibles bifid at the tips.

3. Rather slighter in build than the 9, the head and sides of the

thorax usually more or less clouded with fuscous; the pygidium and

5th ventral segment of the abdomen both deeply cleft at apex (in the

2 the apex of the pygidium has a small angular emargination).

Length.—9-13 mm.

Localities.—Table Mountain (W. Bevins); Darling (L. Péringuey) ;

Grahamstown; Touws River, November 1883 (L. Péringuey) ; Durban

(J. P. Cregoe and H. W. Bell-Marley); also in Europe, Asia, North

and South America.

This widely distributed species of Palaearctic origin is probably

distributed largely by driftwood, in which the larva frequently lives.

Apart from the generic characters, it is readily distinguished by its

colour pattern from all other South African members of the family.

From certain species of Asclerosibutia which also have the tips of the

elytra black it is at once separated, in addition to its generic differences,

by its head being concolorous with the prothorax.

MELANANTHIA gen. nov.

Elongate, subcylindrical, moderately densely pubescent. Head,

excluding labrum, about as long as its width between the eyes, the

latter strongly convex, entire, a little longer than wide, their long

axis (viewed laterally) very oblique; antennae slender, second joint

about 4 as long as third, 11-jointed in both sexes, inserted about

equidistant from the eyes and the base of the mandibles; labrum

about half as wide again as long; mandibles bifid at apex ; maxillary

palpi with last joint triangular, apex about as long as inner side,

The Oedemeridae of South Africa. 359

rather more than half as long as outer ; last joint of labial palpi with

sides equal and slightly divergent, apex rounded. Prothorax cor-

diform. Elytra parallel sided for three-quarters of their length,

each with four costae extending almost to apex. Anterior tibiae

with two small spurs at apex, penultimate joint of all the tarsi

expanded and clothed beneath with dense fulvous pubescence, with

a slight development of similar pubescence on the antepenultimate

joints.

3 with 5th ventral segment only about half as long as 4th;

- 6th segment divided, forming two long narrow lobes.

©, 5th ventral segment produced in a triangular lobe.

Closely related to Chrysanthia Schm., from which it differs in the

lack of metallic colour, in having the head withdrawn to the eyes

in the prothorax, the second joint of the antennae shorter, the labrum

broader, etc.

M. costupennis sp. n.

Black, with the head and prothorax mainly testaceous, the antennae,

mouth parts, except mandibles and mentum, and the gula, a spot

on the vertex, and a median elongate patch on the thorax black ;

legs entirely black except the front coxae yellow. Thorax a little

wider than long, with a broad transverse depression across the middle,

less intense in the median area; pubescence of head and thorax

golden except on the black areas, where it is black, and directed

mainly towards the median line, near which it slopes forwards ;

puncturation rather strong, coarser and more sparse on the depressed

areas. Hlytra with the margins and four costae on each strongly

raised and shining, with rather sparse decumbent black pubescence

directed backwards; intervals densely granulose, with cinereous

decumbent pubescence on each interval directed backwards and to-

wards the middle line, so that it appears denser and whiter in the

middle of each interval. |

$. The short 5th ventral segment with a small median projection

and the sides more strongly produced, the 6th segment completely

exposed, as two long laminae, separated and twisted in apical third,

exposing a stout pointed median piece, dorsal to which projects the

aedeagus, the terminal knob of which is separated by a sharp bifid

notch on both dorsal and ventral sides ; again dorsal to this are two

slender brown chitinous rods, the lateral lobes of the tegmen.

emarginate before the apex, thus forming a broad triangular median

lobe ; apex of pygidium entire.

Length.—9-12 mm.

Locality.—Pondoland, Port St. John, Oct. and Dec. 1923 (R. E.

Turner).

1 3 and 3 99 of this striking species are before me. The strongly

costate elytra, the effect of which is enhanced by the diversity of

colour of the pubescence and its peculiar incidence, render the species

at once recognisable.

Melananthia senex, sp. n.

Klongate, subparallel, black with a slight aeneous lustre, covered

with a conspicuous decumbent white pubescence; the antennae,

palpi, mandibles (with the exception of the tips), and legs, more or less

testaceous.

Head across the eyes as wide as the prothorax, sharply constricted

immediately behind the eyes; the latter almost contiguous with the

front of the prothorax, not emarginate in front, strongly convex and

prominent, the distance between them notably greater than that

between the antennae; antennae inserted some distance in front of

the eyes, slender, second joint elongate, 4 as long as 3rd, 3rd to 10th

cylindrical, decreasing slightly in length; mandibles bifid at apex ;

maxillary palpi normal, last joint triangular, not much longer than

the preceding, its inner edge about as long as the apical. Thorax

slightly longer than wide, feebly enlarged in anterior half, anterior

border rounded, base bisinuate, disc convex without definite 1m-

pressions, finely and evenly granulate-punctate except for a smooth

median line in the posterior half; pubescence rather irregularly

inclined, directed mainly forwards on the disc, transversely inwards

along the basal border, leaving a narrow sub-basal line as well as the

smooth line on the disc free of pubescence. Elytra parallel in basal

half, thence arcuately narrowed to apex, sutural border slightly raised,

disc punctured similarly to the thorax, pubescence directed backwards

somewhat obliquely in alternating directions, leaving three rather

indistinct dark lines where it is less crowded. Anterior tibiae with

two spurs, basal joint of posterior tarsi a little longer than the rest

together, penultimate joint cordiform, deeply excavate above, slightly

wider than the preceding, claw-joint about as long as second ;_ claws

subdentate within at the base.

Length.—11 mm.

Locality.—Cape Town, 20th December 1911 (K. H. Barnard).

The type, 2, is unique in the British Museum.

Differs from the type species of the genus in its more elongate, less

cordiform thorax, and in the elytral costae being indicated by the

trend of the pubescence rather than definitely present. With the dis-

covery of the g it may be found that a new genus is required for its

reception. The uniformly blackish colour of the body, to which the

conspicuous white pubescence gives a slate-grey appearance, at once

distinguishes it from all other South African members of the family.

In this respect it resembles the Egyptian Probosca pallipes, Oliv., but

the latter has the eyes much less prominent, emarginate in front,

and separated above by a distance scarcely greater than that between

the antennal bases.

APTEROSESSINIA gen. nov.

Head sunk to the eyes in the prothorax; eyes large prominent,

broadly but shallowly emarginate in front, separated by a space about

equal to that between the antennal bases; antennae inserted close

to the eyes, filiform, 2nd joint about 4 as long as 3rd, mandibles dis-

similar, left simple, right with a small tooth above before the apex ;

palpi not unusually large, last joint triangular, outer edge sinuate,

inner much shorter than the apical. Thorax cordiform, rounded in

front, disc convex without marked impressions. EHlytra not much

wider than the thorax, parallel, each separately narrowed and rounded

at apex, hence dehiscent for some distance before apex, all four costae

faintly evident ; wings vestigial ; pygidium exposed, sides convergent

from base, apex broadly truncate ; last ventral segment subtriangular,

sinuate on each side and rounded at apex, not attaining tip of pygidium.

Anterior tibiae with two spurs, tarsi slender, Ist joint of posterior

tarsi as long as the rest together including the claws, penultimate

joint cordiform, deeply excavate above, spongy pubescent beneath ;

claw joint as long as 2nd, more than half its length projecting beyond

the penuJtimate, claws with a long curved tooth on inner side. Sexes

very similar except that the 9 is very much larger than the 3.

The new species for which this genus is proposed bears < striking

resemblance to the New Zealand form Thelyphassa diaphana, Pasc.

though differing from it in numerous details. In the dissimilar

mandibles it resembles Alloxacis Horn, though its micropterous state

and projecting pygidium give it a very different aspect. From

Sessinia it differs, besides being subapterous, in the toothed claws.

The latter might almost be described as “ split”’ as in the Meloidae,

the tooth being slender and curved, almost as long as the claw itself.

Annals of the South African Museum.

Apterosessinia peringuey2, sp. 0.

EHlongate, parallel, except for the eyes and the tips of the mandibles

entirely testaceous, clothed with a moderately dense decumbent pale

pubescence.

Head more or less nitid, finely and not very densely punctate.

Thorax longer than wide (scarcely so in 9), anterior margin rounded,

sides strongly sinuate, hardly wider than the head across the eyes

in 3, considerably wider in 9, base strongly bisinuate with raised

border ; disc punctured as the head, pubescence mainly directed

obliquely inwards at the sides and forwards in the middle. EHlytra

scarcely wider than the widest part of the thorax, parallel, nearly

flat behind, much more opaque than the thorax, but little more densely

punctate and pubescent, reaching little beyond the base of the pygi-

dium. Wings aborted, parallel, about half the length of the elytra.

3S. Eyes larger and more prominent, thorax more elongate, more

strongly sinuate at the sides. The genital armature seen from

beneath, lying within the concavity of the pygidium, exhibits the

following pieces, viz., 6th ventral segment consisting of a pair of

lanceolate lobes lying horizontally, each of these near the base is

suddenly expanded to form a large unciform process which nearly

meets its fellow; between these is a median slender, clavate, hairy

process, its tip not quite attaining the tips of the above-mentioned

lobes; dorsal to this the tegmen gives off two somewhat scimitar-

shaped lobes held vertically between the lobes of the 6th segment and

projecting a little beyond them, while above them lies the median

lobe, flattened laterally with on each side before the tip a fine barb

on the ventral edge (cf. Oncomera, Sharp and Muir, Trans. Ent. Soc.

Ibyeraelg, USI, 10, BIDE, jall, Ibex, ial, IKeNN),

Length.—(Average) 13 mm. (9-18).

©. Larger and more stoutly built, eyes smaller and less convex,

thorax shorter, less strongly sinuate at the sides, considerably wider

than the head across the eyes; pygidium and 5th ventral segment

very similar to those of the g; colour a little redder.

Ananca Fairm. and Germ.

To this genus, originally proposed for certain Chilian species, I

assign numerous Sessinia-like forms which differ from Sessinza Pasc.

(type lweda, F.) in having the mandibles bifid at the apex. This

character is not always easily perceptible from above, especially when

the jaws are closed, but if examined from beneath the deep groove that

leads up to the apex can usually be seen even when the extreme tips

are concealed. Fairmaire used the name for a considerable number

of species from Madagascar, though some of these no doubt belong

elsewhere. His remarks (1897) on the excessive rarity of the males

of most of the species are not borne out by the material now before

me, but there is reason to suppose that he frequently failed to recognise

this sex. From the description he gives of the 3 characters of A.

helvola, Klug, a species unknown to me, it would appear to be wrongly

placed in this genus, since he describes a strong sexual dimorphism

in the apparent terminal segments of the abdomen, whereas in Ananca

as here understood such dimorphism is remarkably slight; the

probability is that many of the specimens presumed by Fairmaire

on account of the simple abdomen to be female were in reality male.

When the apex of the abdomen gapes the genitalia, enclosed between

the lobes of the 6th ventral segment, can usually be seen lying within

the hollow of the pygidium ; the terminal papillae of the ovipositor of

the 2 usually at once make that sex recognisable.

12. (9) Elytra rather sparsely punctate and pubescent, paler than the head and

thorax ; abdomen fuscous . : : : fusciventris, sp. n.

Ananca imconstans, sp. 0.

Robust, reddish yellow, with the antennae, palpi, tibiae and tarsi,

and the greater part of the elytra black; the latter have an orange

border expanded at the apex, and frequently an irregular band of the

same colour, varying greatly in width in different specimens, across

the middle.

Head sunk almost to the eyes in the prothorax, moderately strongly

punctate, each puncture with a scarcely visible hair. LHyes large,

not very convex, widely emarginate in front, slightly more approximate

above than the antennal bases. Antenna inserted close to eyes, rather

stout, filiform, 2nd joint about 4 as long as 3rd. Mandibles bifid at

apex; palpi slender, last joint about 4 longer than the second, its

outer edge sinuate, the inner edge not very divergent (about 30°),

nearly as long as the apical. Thorax cordiform, a little wider than

the head across the eyes, about as wide as long, widest near the front

thence sharply narrowed anteriorly and more gently so towards the

base, which is bisinuate with a raised border; disc uneven, with a

broad depression across the anterior half, with extensions towards the

anterior angles, the middles of the sides, and to a median basal

depression ; surface strongly, rather densely, punctate with scarcely

visible pubescence. LElytra widest behind the middle, not very

convex transversely, finely granulate, with a double pubescence, very

fine decumbent with sparser-stronger semi-erect hairs interspersed.

Tarsi stout, basal joint of posterior tarsi longer than the rest together,

penultimate joint cordiform, excavate above, with a dense golden

pubescence beneath, scarcely wider than the preceding.

Sexes very similar; 3, pygidium cleft at apex, genital armature

very similar to that of Apterosessinia described above, but stouter,

with median lobe more pointed, and the subapical barbs stouter and

more divaricate, thus approaching the form of an arrow head, with

a second pair of barbs some distance behind them.

Length about 13 mm. (10-17 mm.).

The Oedemeridae of South Africa, ° 361

The colour pattern is independent of sex, but from the limited

material before me there may be some connection with the geographical

distribution of the species. Thus I have forms in which the transverse

bar has disappeared more or less entirely from Nyasaland and Natal

(Malvern and Durban); the form with the band normal from Natal

and Ngami, that in which it has increased so as to occupy almost half

the length of the elytra from Mossel Bay and Mpanzi R. Further

collecting, however, may demonstrate that all these forms may occur

together.

This type of coloration is very unusual in the family, though found

in certain Australian species, e.g. Coprdita languida, Blkbn. and others,

and in S. Moorez, Montr. from New Caledonia and Fiji.

Ananca marginipennis, sp. n.

Slender, flavous, with the antennae, palpi, tibiae and tarsi, and

elytra black, the latter with a narrow flavous border which is not

continued round the apex; head and thorax more or less marked

with fuscous.

Head not quite sunk to the eyes in the prothorax, not notably con-

stricted behind the eyes, finely and moderately densely punctate,

with a fuscous patch between the eyes though sometimes not reaching

them. KHyes large, not very convex, broadly but not deeply emarginate

in front. Antennae inserted close to the eyes, slightly more approxi-

mate than the latter, filiform, attaining ($) about the middle of the

abdomen, 2nd joint rather more than 4 the length of the 3rd; man-

dibles bifid at apex ; last joint of palpi with the inner edge little more

than 4 as long as the apical. Thorax in 3 not quite as wide as the

head across the eyes, slightly longer than wide, in 9 a little wider than

the head and about as wide as long, disc punctured and pubescent as

the head, with a large shallow depression on each side about the middle.

Elytra parallel, about 3 times as long as wide, each with 4 raised

lines of which the 2 outer are very faint, finely and moderately

densely punctate, with the intervals minutely rugose, pubescence

simple, golden, and moderately dense. Anterior tibiae bispinose, tarsi

moderately stout, basal joint of posterior tarsi longer than the rest

together, penultimate joint cordiform, wider than the preceding,

deeply excavate above; all the joints except the claw-joint clothed

beneath with a dense golden pubescence, that on the second joint

apparently of a velvet-like character similar to that of the penultimate.

Length.—9-11 mm.

November—December 1911 (G. A. K. Marshall).

Of the African forms this only in any way resembles the unbanded

form of S. enconstans, sp. n., but is of much more slender build, and

may be at once recognised by the simple elytral pubescence, by the

less approximate eyes, and by the yellow margin of the elytra being

interrupted at the apex. Like S. wnconstans it bears a close superficial

resemblance to certain Australian forms, e.g. S. Macleayi, Champ.

and S. punctum, Macl.

Ananca nigrimembris, sp. n.

Clear luteous with the maxillary palpi (antennae wanting), tibiae,

tarsi, and apices of the femora black.

Head not withdrawn as far as the eyes in the prothorax, not con-

stricted behind the eyes, rather strongly punctate but with very feeble

pubescence; eyes large, moderately prominent, broadly but feebly

emarginate in front, slightly wider apart than the antennal bases ;

mandibles bifid at apex, maxillary palpi slender, last joint about

twice as long as the preceding, outer and apical edges scarcely diverging,

inner edge very short. Thorax longer than wide, scarcely wider than

the head across the eyes, sides strongly sinuate, base feebly bisinuate

with raised border, disc depressed with a median shallow impression

before the base and a pair in front of the middle, surface rather strongly

punctate, with weak forwardly directed pubescence. LElytra elongate,

parallel, more opaque than the thorax with four raised lines, pubes-

cence stronger than that of thorax, golden. Posterior tarsi slender,

penultimate joint scarcely wider than the preceding, both, and the

apex of the basal joint, with dense golden pubescence beneath ; claws

simple.

Length.—9 mm.

Locality. Nyasaland : Mlanje, 16th November 1912 (S. A. Neave).

The single specimen, sex not determined, is distinct from every

other African species known to me by its black appendages in contrast

with the yellow body. It may prove to be synonymous with S.

bicoloripes, Pic (1922) from San Thomé, which is described as being

similarly coloured, but the description is too meagre for definite

recognition, and in view of the wide difference in the localities, and of

the apparent distinctness of the South and Hast African forms from

the West African, the probability appears to be in favour of their

being distinct.

Ananca hottentota, Fairm.

Bull. Soc. Ent. France, p. 71, 1883.

EKlongate, brownish testaceous, the antennae with the apical half

of joints 3-7 (the rest wanting) fuscous, 2nd joint 4 as long as the 3rd ;

thorax clouded with fuscous at the sides.

Head comparatively coarsely punctate and finely rather sparsely

pubescent ; eyes widely but shallowly emarginate, mandibles bifid

at apex, last joint of palpi triangular, inner side as long as apex.

Thorax subcordiform, widely depressed above, with the usual de-

pressions rather feeble, sides rather strongly constricted about the

middle; surface rather coarsely and sparsely but somewhat ir-

regularly punctate, with fine sparse pubescence. Elytra 3 times as long

as together wide, a little darker than the thorax, and much more finely

and densely punctate, all 4 raised lines evident. (Legs defective.)

Length.—13 mm.

Locality—Mossel Bay, January 1899 (T. W. Overbeek), in South

African Museum. (Described from the Cape.)

I have not seen any authentic individual of this species, but Dr.

Péringuey informs me that he thinks the defective 2 above described

is of the same species as that he had originally sent to Fairmaire.

It agrees fairly well with the description given by the latter author,

but is a little longer. The annulate antennae are very striking and

at once distinguish the species from the other African representatives

of the family.

Since the above was written I have received a further pair of

A. hottentota from Tokai, Cape Province, 10th October 1923 (N. L.

King) from under the bark of eucalyptus trees grown from seed.

From these it is possible to supplement the above description :

Femora mainly fulvous with the apex as well as the tibiae and tarsi

darker.

Sexes, even as regards antennae, palpi, position of eyes, etc., very

similar, but strongly dimorphic in the genitalia.

3, 5th ventral segment broadly emarginate at apex, but the median

portion again triangularly produced, 6th segment divided almost to

base to form a pair of narrow divergent lobes the apices of which are

' twisted (2.e. dorsal surface becomes ventral) and curve towards one

another again. Between these is the aedeagus, the lateral lobes

narrow, lanceolate, the median lobe provided on its dorsal side near

the apex with two barbs, of which the apical is the larger.

564 Annals of the South African Museum.

2, 5th ventral segment subtriangular, the apex not quite reaching

that of the pygidium.

This strong sexual dimorphism in the genital armature is very

unusual in Ananca, and suggests that the genus may be composite

(see above under Ananca). While there is some resemblance between

the ¢ genitalia here described, and those of A. helvola Kl. and A.

foveicollis Fairm. described by Fairmaire, there is no suggestion of

an intimate relationship, since Fairmaire describes only 4 ventral

segments to the abdomen.

The habitat under the bark of Eucalyptus, in conjunction with other

previously noted resemblances of South African to Australian and

New Zealand species, suggests an inquiry whether it, or its ancestors,

might not have been imported with the eucalyptus, but it is certainly

not assignable to any Australian species known to me, while the fact

that it was described from South Africa forty years ago and was again

taken in 1899 does not afford any valid support to such a theory.

Ananca holoxantha, Har.

Col. Heft., vol. xvi, p. 145, 1879.

Brownish testaceous, densely and finely punctate and pubescent

throughout.

Head retractile to the eyes in the prothorax; eyes feebly convex

and feebly emarginate in front; 2nd joimt of antennae nearly 3

as long as the 3rd; mandibles bifid at apex; last joint of maxillary

palpi triangular, inner side nearly as long as the apex. Thorax

cordiform, rounded in front, the sides gradually convergent behind,

disc convex, with scarcely indicated depressions, closely and finely

punctate. Elytra not 3 times as long as together wide, slightly

darker than the head and thorax, with the suture narrowly paler;

the usual raised lines are scarcely indicated. Tarsi slender, basal

joint of posterior tarsi as long as the rest together, penultimate joint

small, cordiform scarcely wider than the preceding, claw-joint pro-

jecting for 2 of its length beyond it: claws simple.

2nd joint of the antennae is evidently more than 4 as long as the 3rd,

the elytra are not wider behind the middle, and have faint indications

of the usual raised lines. Both specimens appear to be of the same

sex, one of them being obviously 9.

Ananca subfasciata, sp. n.

Pale dirty yellow with an indistinct broad dark band across the

base of the elytra and another beyond the middle.

Head wider than the prothorax, slightly narrowed behind the eyes,

rather short in front. Eyes large, prominent, widely but shallowly

emarginate in front, distance between them rather greater than that

between antennal bases. Antennae inserted close to eyes, filiform,

2nd joint about half as long as 3rd; labrum transverse, mandibles

strongly curved externally, bifid at apex; maxillary palpi slender,

last joint about twice as long as 2nd, outer and apical sides curved,

inner very short, giving the joint a subcrescentic outline. Thorax

as wide as long, strongly sinuately narrowed towards base, rounded in

front, disc with a broad shallow depression across the anterior half

and produced basally as a median depression, very finely and not

closely punctate and pubescent. Hlytra more densely and strongly

pubescent than the thorax, each with 4 raised lines, the 3rd (humeral)

only visible near the base. ‘Tarsi slender, Ist joint of posterior

tarsi longer than the rest together including the claws, penultimate

- not markedly wider than the preceding, densely pubescent beneath.

3 pygidium slightly emarginate at apex.

Length.—6-7 mm.

Localities.—Clanwilliam, O’Okiep, November 1885 (South African

Museum).

A very fragile insect, the soft teguments and indistinct colour

pattern giving it the appearance of immaturity, though both the

individuals before me are alike. The short head and peculiar shape

of the terminal joint of the palpi are very distinct, and in conjunction

with the small size and feeble coloration should render the species

easily recognisable. The form of the palpi does not appear to be

sexual; in both specimens they are similar, though the second, in

which however the genital armature is not visible, has the pygidium

entire at the apex, and is presumably 9.

Ananca fuscwentris, sp. 0.

Flavous, the elytra notably paler than the head and thorax, the

metasternum and abdomen fuscous.

366 Annals of the South African Museum.

Head retractile to the eyes in the prothorax, rather strongly but

not very densely punctate and pubescent; eyes large, moderately

convex, feebly emarginate in front, somewhat more approximate than

the antennal bases. Antennae slender, inserted close to the eyes,

2nd joint rather more than 4 as long as 3rd; mandibles toothed

beneath at apex, curved in about a quarter circle from the front.of

the clypeus; maxillary palpi slender, last joint half as long again

as the penultimate, the inner side about as long as the apical.

Thorax longer than wide, scarcely as wide as the head across the eyes,

with the usual impressions very feeble ; surface more sparsely punctate

than the head, punctures large, shallow, more or less pupillate, the

intervening space finely alutaceous. Elytra with the usual raised

lines ill-defined, rather sparsely punctate, each puncture with a rather

long suberect hair. Anterior tibiae bispinose, tarsi moderately stout,

basal joint of posterior tarsi as long as the rest together (excluding the

claws) penultimate joint cordiform, wider than the preceding. dg not

Localitees.—Beira, Port. EK. Africa, Ist June 1900 (G. A. K.

Readily recognised among the African members of the family by

its colour and its comparatively sparse and coarse pubescence. It

is closely allied to Ananca scabripennis, Champ. (1917) from the

Seychelle Islands and Christmas Island, with which the peculiar punc-

turation of the thorax agrees, but the elytra are more sparsely punctate

with longer pubescence, and the colour of the underside is different.

Sessinia Pascoe.

In this genus are retained only those species in which the mandibles

are simple at the apex, though in some cases there is a blunt tooth

on the upper edge of the inner side a little before the apex. In Ananca

the outer edge bears a deep groove, frequently visible only from

beneath, a little before the apex which ultimately splits it into two

sharp teeth, the upper usually the larger. Fairmaire seems to have

paid no attention to this character, and it is probable that many of

the species included by him in Ananca should really be referred here.

The two genera are in other respects almost identical and have a

similar distribution throughout the tropics of both hemispheres.

Though this character may appear trivial it appears to be sharply

defined (in a family where good characters are scarce), and consider-

able importance has been attached to it by most recent writers on

the Oedemeridae.

Champion (@917) has recently used Oxacis, Lec. for this genus,

treating Sessinia as a nomen nudum synonymous with Ananca,

F. and G., but Iam unable to follow him in so doing. The name was

proposed by Pascoe (1863) for a group of known species for which

generic characters, though no name, were given by Lacordaire (1859),

and appears to be perfectly valid. The first of these species quoted

by Lacordaire, Lagria lida, ¥., later selected by Semenow (1894)

as the type of the genus, has simple mandibles, so that Sessinia Pasc.

may be separated from Ananca Fairm., with which it was formerly

combined and synonymous, on these grounds, and Oxacis Lec., at

least as applied to the African fauna, becomes a synonym of it.

This insect resembles in colour and pubescence that which I take

to be A. holoxantha, Har. The latter, however, is very much smaller,

has the mandibles bifid at apex and more strongly curved, the

slender, and the 2 has the apex of the pygidium widely and deeply

notched at the apex.

Sessinia vittatithorax, sp. n.

Robust, flavotestaceous, with the head between the eyes, a median

line along the thorax, and the elytra brownish, the latter with the

Head retractile to the eyes in the prothorax, finely, rather closely

punctate, with indistinct pubescence. Eyes large, rather strongly

convex, separated above by a space about equal to the breadth of

one of them, feebly emarginate in front. Antennae filiform, nearly

Length.—12 mm.

Locality.— Natal, Isipingo, February 1896 (G. A. K. Marshall).

The single specimen has the facies of a large group of species widely

distributed in the tropics and closely resembling one another, though

differing widely in the minute sculpture of the thorax. It must be

very similar to Ananca strigicollis, Fairm. from Madagascar, but has

no trace of a median sulcus on the thorax and is not darker beneath.

It also resembles A. grisescens, Fairm. but is darker in colour, with

quite different thoracic sculpture and mandibular structure. Ozxacis

nquisttor, Blkb., an Australian species, has very similar sculpture

and coloration, but differs in the palpi, the inner side of the last joint

being distinctly shorter than the apical.

Sessema marshalli, sp. n.

Pale flavous, with the head between the eyes, a median line on the

thorax, and the elytra, except the margins, clouded with fuscous.

Head retractile to the eyes in the prothorax, finely and rather

sparsely punctate and pubescent; eyes large, prominent, feebly

emarginate in front, separated above by a space greater than the

width of one of them; antennae inserted close to the eyes, 3 to #

as long as the body, 2nd joint about 4 as long as 3rd; mandibles

acute at apex; maxillary palpi normal, last joint about half as long

again as the 3rd; inner side as long as apical. Thorax as long as or

longer than wide, subcordiform, without pronounced impressions,

sparsely and finely punctate and pubescent, the general surface smooth

and nitid. Elytra more densely asperately punctate with stronger

decumbent pubescence, without evident raised lines; apex of

pygidium rounded, entire. Anterior tibiae bispinose, tarsi slender,

basal joint of posterior tarsi as long as the rest together (excluding the

claws), penultimate joint cordate, a little wider than the preceding.

3 slightly smaller than the 2, more slender, the thorax longer than

wide, scarcely as wide as the head across the eyes (as wide as long

in the 2 and slightly wider than the head across the eyes) antennae

longer, extending beyond the middle of the elytra.

Very like a small pale-coloured form of the preceding, but the

distance between the eyes is greater, and the thorax is very differently

sculptured.

Ananca phthysica, Rits. from the Congo and Sessinia lateritincta,

Pic from the Gaboon (if these are not identical) probably should also

be included in this genus. The British Museum possesses specimens

from Nigeria with the name Nacerdes limbata, De}. (MS.), that appear

to agree with the description of both. Of the same general form as

S. vitatithorax, sp. n. they differ in having a broad though rather

indistinct fuscous streak from the humerus nearly to the tip of the

elytra but not including the margin. The thorax is very indistinctly

darker in the middle, the anteromedian portion of the disc densely

and rather coarsely punctured with a tendency to a median line free

of punctures, but basally and laterally the punctures become much

finer and more crowded.

Asclerosibutia, Pic.

L’Kchange, vol. xxx, p. 67, 1914.

This genus, with three species from West Africa and the Congo, has

not hitherto been recognised from the southern or eastern part of the

African continent. It is placed by Pic near Asclera, but the author

makes no mention of the palpi or of the abdominal sexual characters.

If I have recognised it correctly it belongs to the subfamily of

Oedemerinae, and not to the Asclerinae, as witnessed by the long narrow

terminal joint of the palpi, the comparatively deep, angular, emargina-

tion of the eye, and the strong sexual dimorphism exhibited by the

abdominal segments. It is perhaps scarcely distinct from the tropical

American genus Sisenes, Champ., but the name may provisionally be

retained for the African species. These appear to fall into two, or

perhaps three, distinct groups according to the formation of the

abdominal segments.

2. 5th ventral segment very obtusely angulate at apex, almost

concealing the ovipositor when in resting position ; 6th sclerite

divided as above.

A. violacea, of which the 9 is unknown.)

S$. 5th ventral segment conical, broadly, subrectangularly

emarginate at apex so as to reach only half the length of the

pygidium, exposing the two comparatively small rounded lobes

of the 6th segment, which lie in a horizontal plane and nearly

meet posteriorly. Between and beyond them is visible the

aedeagus which extends, in the position of rest, to the tip of

the pygidium.

°. Sth ventral segment triangular, extending nearly to

the tips of the pygidium; 6th sclerite divided, completely

concealed when at rest.

To the first group belong apparently all the species described by

Pic. They are larger, more robust-looking insects than those of the

other groups, with the elytra more densely pubescent and having a

striped appearance owing to the different directions in which the

pubescence lies. The suture and outer margin are thickened, and

there are two raised costae—one dorsal, arising from above the humeral

angle, and one sublateral, arising below it. On all these raised lines

the pubescence lies directly backwards. Between the suture and the

372 Annals of the South African Museum.

dorsal costa it is directed obliquely backwards, outwards from the

suture, inwards from the costa, the two series forming a crest midway

between the two; between the two costae it forms a similar crest.

In the 9 the last joint or two joints of the antennae are yellowish, but

in the only 3 seen by me they are concolorous black.

In the second group the two costae though present are much less

prominent and do not influence the trend of the pubescence. This

lies backwards along the suture, then obliquely outwards to a line

halfway between the dorsal and sublateral costae, beyond which it

lies again backwards. I have seen no ¢ of the South Hast African

species of this group, but A. violacea, sp. n. from West Africa is

presumed to belong to it.

The third group is necessary for A. terminalis, sp. n. which agrees

in facies and also in the way in which the pubescence lies with the

second, but exhibits certain differences in the posterior abdominal

segments in both sexes which seem to separate it rather sharply.

It is possible, however, that the discovery of the $ of A. neaver and

its allies may render this distinction less abrupt.

From Uganda the British Museum possesses what is probably a

variety of one of the West African species described by Pic :—

on the sides, the last two joints of the antennae fulvous. The head

CuRRAN, Ottawa, Canada.

(With Plates IX and X.)

THE preparation of the manuscript describing the two-winged flies

of the family Dolichopodidae, contained in the collection of the South

African Museum, was entrusted to the author by the late Dr. Péringuey.

It has been a great pleasure to examine this second collection of

beautiful small flies from South Africa, to redescribe several of the

species and to add several new ones to the list, and my appreciation

of the late Director’s kindness is very great. Including the species

herein described as new, there are now about two score recognised

from South Africa. Undoubtedly there are still many times this

number to be found.

The Dolichopodidae are interesting because of their beautiful

coloration, unexpected development of various appendages, and also

because of the shght knowledge we have of their life-history. They

are often found in large numbers about the edges of pools and streams,

performing their interesting mating evolutions, wherein the males

display their often remarkable sexual developments before the females.

Most of the species will be found crawling about upon the mud, or

even upon the surface of the water, but a few are found almost entirely

upon foliage at not too great a distance from moisture. A few inhabit

the seashore, while others are found upon moist sand, and one or two

genera upon the trunks of trees. Most of them are found almost

entirely in bright sunny patches while a few prefer the shade. Small

moist clearings in woods are favourite haunts of many of them.

Usually several species, and various genera, may be found together.

The classification of the family is generally rather simple where males

are concerned, but the females cause much more difficulty. The

specialisation of the male secondary ‘sexual characters has been

greatly used in separating the genera, as well as the primary separation

upon the large or small genitalia. As the females invariably lack

ornamentation they have been sadly neglected, and the only way to

become familiar with the species is to collect and study both sexes

together. This necessitates the collection of large numbers of

specimens of each species. As it is very often impossible to distin-

378 Annals of the South African Museum.

guish two species in the field, such a practice frequently results in a

pleasant surprise when the material is examined, as one may find

that two or more species have been taken where only one was

suspected.

In the following descriptions I have used the terminology of the

legs, wherein I consider that all the legs are spread out at right angles

to the body. Thus, the anterior surface of a leg is always the same,

the posterior also the same. In this way confusion resulting from

calling the anterior surface of the front leg the inner surface while

the posterior surface of the hind leg is also termed the inner surface

is avoided. For convenience I have also termed the whole back of

the head the occiput, as I see no reason for restricting the term to

the region lying between the vertex and the neck. The other terms

used are those generally employed by students of the family, and

generally accepted by dipterologists. In general I have followed the

descriptions of Loew more or less as to style, and the terminology is

very much the same; I know of no one who has prepared finer

descriptions and see no reason to change the general terminology he

used, except in one or two cases where the meaning was not clear.

It is hoped that the following treatment may prove simple enough

to enable those unfamiliar with the group to determine their specimens

correctly, and that it may thus prove an incentive to a more intensive

study of the family to some one on the ground who has the time to

collect exhaustively. There are still a few species described by Loew,

which I have not seen, and these are naturally not included in the keys.

In addition, several species described in a recently published paper on

“ The Dolichopodidae of South Africa,” in the Annals of the Transvaal

' Museum (vol. x, pt. 4, 1924), are not included in the present work.

As these belong to genera in which only one species is known from South

Africa and they are not represented in the collection, the descriptions

or keys to the species do not appear. Owing to the fact that the

collections have been so small, it does not appear desirable to mono-

graph the family until a great deal more is known about them, as such

a monograph would prove very inadequate within a few years.

The types of all the species described in this paper are deposited in

the South African Museum unless otherwise stated, but in every case

paratypes, at least, will be found there. Where the descriptions are

made from two or more specimens of a sex, paratypes are retained in

the collection of the author.

SYNOPSIS OF THE SoUTH AFRICAN GENERA.

In many cases it is very difficult to place the females of the

Dolichopodidae in their proper genera, and because of this fact almost

all keys are based entirely upon the males, which offer very fine

characters. There are, however, characters available for the separa-

tion of the females in most cases, and where they do not occur it would

be well to consider such inseparable groups as a single genus. Except

in the case of Diaphorus and Chrysotus there need be no question about

the identity of females. I hesitate to unite the genera without

further study, as it is possible that some character is available and

may be discovered by close examination of a large number of species,

which will make the retention of the two generic names possible.

There may be some difficulty in using the following key unless

one is careful to make absolutely certain that a character is present

or absent. Some of the characters I have been forced to use in

order to bring the sexes out together are not very conspicuous. A

magnification of at least twenty times should be used; this enlarge-

ment is sufficient for ordinary identification. Unfortunately, many

specimens are always sure to be in poor condition, and in such cases

a character is very liable to be overlooked. Attention is also called

to the possibility of genera not heretofore reported from South Africa

being collected, in which case the synopsis will prove unsatisfactory ;

on the other hand aberrant forms of a genus may not trace out.

Note.—It is often possible to tell whether a female belongs to a genus in which

the genitalia of the male are pendulous by the presence of one to several fine hairs

in the cavity above the anterior edge of the hind coxae, but this character is not

always reliable. There are a few other genera which also possess these hairs,

and some of those with pendulous genitalia lack them. Some species may be

placed in their genera by the presence of only one bristle on the outer surface of

the hind coxa. It must be remembered that these characters are not stable

within a genus, but they may be of assistance where males and females taken at

the same time are difficult to associate.

Readily distinguished in the male by the peculiar wing venation

(fig. 5), shape of genitalia and middle tarsi; the female is quite

different, the wings being marked by two black costally connected

fasciae, the legs paler, etc.

Length,5to6mm. Male.—Face narrow, with nearly parallel sides

on the lower half, moderately, gradually broadened above, argenteous

white pollinose. Front rather narrow, brilliant dark blue. Occiput

green, greyish pollinose, the beard white. Palpi small, black, black

haired ; proboscis reddish brown. Antennae black, the third joint

white pollinose. Scutellum with more or less violaceous reflection.

Anterior coxae yellow, with narrow brown base, the others brownish

with pale apices, greyish pollinose and with fine white pile, the anterior

the tarsi, black; the bases and apices of the femora, more or less, and

the anterior four tibiae, yellowish, although the middle tibiae may be

brownish yellow and are always broadly brown or blackish on the

sides of the segment blackish bronze and subopaque on the immediate

base. Genitalia black, the outer lamellae brown, with brownish hairs.

Abdomen with black hairs and bristles.

Female.—This sex was described by Becker as a distinct species,

but he suspected that it was the female of pateraeformis, which is

undoubtedly the case. Face about twice as wide as in the male, but

still narrow for a female, more or less greenish above. Wings as in

fig. 5a, the markings blackish. Femora and front four tibiae reddish

yellow, the hind femora broadly black on the apex ; base of anterior

four tarsi paler than the apical joints. Legs simple. Abdomen

differing only sexually.

There are 8 females and 1 male from Mulange, Uganda, collected

in November 1922 by Mr. R. Dummer. These specimens are from

the type locality (Uganda). In his description of the female Becker

included South African and Ugandan material, but it appears probable

that the South African specimens represent the species I have described

as C. imitator (see wmitans above). Should Becker have selected his

type from the South African specimens his C. alter would be a good

species, but this seems unlikely, and it will be impossible to definitely

decide the status of these species until the types are compared.

Becker’s description and figure agree with the females described above

much better than with imitans.

resembles in having the wide concave face in both sexes, thinly short

plumose arista, and the acrostical bristles in two rows. It differs from

them in having the fourth longitudinal vein produced forward at a

right angle at about half the distance between the large cross-vein

and edge of the wing, as shown in fig. 6. Genotype: the following

species.

Medetera Fischer.

The species belonging to this genus are usually found on the trunks

of trees, and are almost always dull in colour, as well as being rather

small. Five species, separable by the following synopsis, are to be

found in South Africa.

Medetera normalis Curran.

Curran, Ann. Transv. Mus., vol. x, pt. 4, p. 226, 1924.

Length, 3 mm. Male.—Head silvery pollinose, the ground colour

bluish where at all evident. Antennae brown, the third joint with

evident white pubescence; arista above the middle of the small

cordate third joint, slender. Palpi shining black, with a few black

third much longer than the first, the fourth almost as long as the first.

The first joint of the anterior tarsi is slightly longer than the second.

The hairs of the legs are very short and inconspicuous, except above

the hind femora.

Wings hyaline; the fourth vein approaches the third, its last

section straight, the tips of the two veins moderately separated ; the

distance between the third and fourth veins opposite the posterior

cross-vein is equal to almost twice the length of the cross-vein, which

is rectangularly placed. Squamae and halteres pale yellow, the former

yellow hair, the lamellae bare.

Female.—Differs only sexually.

In addition to the original specimens, I have seen over a dozen others

collected by Mr. Munro at East London during February 1924. A

pair of these are donated to the South African Museum.

Aphrosylus Walker.

This genus has not been previously recognised from South Africa,

and is represented by a single species which is described below. It

is possible that A. griseatus, described herewith, is the same as some

European species, but in the absence of specimens from that region

for comparison, it is considered advisable to describe it in order that

others may be able definitely to associate South African specimens

with something already named.

Aphrosylus griseatus n. sp.

(Figs. 7, Ta, 7b.)

Length, 2°75 to 3-25 mm. Male——Head brownish in ground colour,

the face and occiput very densely greyish pollinose, the front less

thickly so, while the region of the neck is brownish pollinose. The cilia

on the upper half of the occiput are black, on the lower half pale

yellowish or almost white and fairly fine. Palpi reddish, with darker

base, the proboscis with similarly coloured apex, both densely grey

pollinose, the former with some fine black hairs. Hyes whitish or

yellowish pilose. Antennae black, shaped as in fig. 7b. The face is

concave on the upper portion, the lower section more or less roof-like

above the palpi.

Thorax and abdomen brown, densely grey pollinose. The acrosticals

are small and widely separated, arranged usually in pairs, each pair

towards the caudal end successively closer to each other; they reach

only to the middle of the thorax or a little beyond in most specimens

and are often difficult to see. Posterior fourth of the mesonotum

concave. Two hair-like yellow propleural bristles. Scutellum with

four marginal bristles of almost equal size.

Coxae and legs with dense grey pollen, the coxae and femora brown,

with pale apices, the tibiae and tarsi reddish, the latter with the

terminal joint brown and somewhat broadened ; the abundant pollen

makes the colour of the legs very deceptive, and it is possible that the

femora are largely pale apically ; the posterior femora are bare on

404 Annals of the South African Museum,

the median half of the posterior surface. The hair on the legs is short,

erect or suberect, black. The first joint of the anterior tarsi is hardly

as long as the four following joints, the middle ones have the first

joint decidedly longer than the remaining, while on the hind legs the

first two joints are subequal. Legs simple. The hind coxae bear a

median bristle on the outer surface, the remaining coxae are sparsely

clothed with black bristly hairs.

Wings (fig. 7) dull greyish brown, appearing as though they had

been wet. Squamae and halteres yellow, the former finely yellow

ciliate.

Outer genital lamellae leaf-like, elongate-oval, yellowish brown,

grey pollinose; the inner lamellae, etc., shining brown. Abdomen

with sparse black appressed hairs (fig. 7a).

Female.—Difiers only sexually.

This description is from the following specimens collected by Mr.

H. K. Munro on the Beach at East London: 7 4, 12 Q,

17th February; 3 ¢ and 2 9, 14th February 1919.

Hydrophorus Fallen.

Distinguished from other genera by the presence of spines beneath

the anterior femora, absence of mammiform process below the squamae,

and by the posterior cross-vein being situated close to the wing margin.

The following synopsis separates the two species contained in the

‘collection :—

A. Upper portion of the face brilliant green ; . spinicornis Loew

AA. Face wholly greyish pollinose : ’ : : praecox Lehm.

Hydrophorus spinicornis Loew.

the acrostical bristles, between each of which is a pale spot. Pleura

green, with bronze reflections ; grey pollinose. Scutellum bronzy, the

corners green ; bearing four bristles.

Legs green ; tarsi black, the hind ones brown. Coxae densely grey

pollinose and white pilose. Front femora with an anterior and

posterior row of spines on the ventral surface, the spines rather fine

and decreasing in length from the base, both rows interrupted near

the middle ; neither row reaches the apex, but the hind row is shorter ;

on the basal half of the postero-ventral surface are several long, fine

white hairs. Front tibiae with an entire row of fine short bristles

on the ventral surface, the terminal one not strengthened nor long ;

above with four small bristles. Tarsi simple. Legs otherwise not

distinctive, their hairs black.

Wings hyaline. Squamae and halteres yellow, the former white

ciliate.

Abdomen green, with bronze reflections, the sides thickly grey

pollinose, the dorsum moderately covered with brownish pollen.

The male genitalia are small.

There are four female specimens of this pretty species in the

collection, three from Cape Town, collected by Dr. Péringuey in 19138,

and one from Junction of Crocodile and Marico Rivers, Transvaal,

February 1918, collected by Mr. R. W. E. Tucker.

Hydrophorus praecox Lehm.

Owing to the fact that no male specimen is present in the collection,

I quote the description of Lundbeck, as given in the English edition

of part 4 of his Diptera Danica.

“ Male.—Length, 2-5 to 4-5 mm. Head as high as broad; vertex

and frons aeneous, somewhat greyish pruinose at the sides. Face

broad, greyish white, the palpi of the same colour. Occiput greenish,

grey pruinose; postocular bristles black, the hairs below white.

Jowls distinct, not broad, grey. Antennae black, third joint slightly

longer than broad, pointed ; arista a little longer than the antennae.

Thorax olive, sometimes greenish, especially at the sides, and more or

less with coppery reflections, a little pruinose, somewhat shining ; in

the middle there is a dark stripe divided by a very fine pale line, and

to each side of the dark stripe the green colour forms more or less

distinct stripes; dorso-central bristles numerous. Scutellum with

four bristles. Pleura greenish or aeneous, densely whitish grey

406 Annals of the South African Museum.

pruinose ; propleura with grey hairs and one black prothoracic bristle.

Abdomen somewhat flattened, greenish, aeneous or coppery, rather

densely greyish white pruinose ; it is somewhat densely covered with

pale hairs a little longer at the sides. Venter grey. Hypopygium

generally quite hidden. Legs quite green, coxae light grey pruinose,

femora and tibiae somewhat pruinose, the tarsi blackish. The legs

have short black hairs intermingled with pale pubescence, the latter

especially distinct towards the end of the tibiae and on the tars! ;

coxae pale haired; front femora with a row of short spines below

towards the anterior side, the front tibiae with a row of short spines

below, the apical one large and strong, besides with a few small dorsal

bristles ; posterior femora and tibiae with various scattered, not long,

bristles. Wings somewhat long, hyaline; veins black, paler towards

the base; the last part of the discal (fourth) vein slightly curved, a

little converging towards the cubital (third) vein. Squamae whitish,

with white fringe. Halteres whitish or whitish yellow.

‘“ Female.—Face not broader than in the male. Front femora with

two rows of spines, as there is, besides the row found in the male, one

more posteriorly ; apical spine below the front tibiae shorter than in

the male.”’

Five specimens, all females, agree almost perfectly with specimens

from Denmark. Until the male is compared with Huropean specimens

there must be a slight doubt about the South African specimens being

praecox.

Inancalus Loew.

This genus is readily distinguished from all others in the family

by the long mesopleural process projecting along the posterior outer

base of the anterior coxae. Only the following new species is known ~

from South Africa, while ZL. virens occurs in northern Africa and Europe.

These are among the largest and most brilliantly coloured members

of the family, and the males usually possess a striking pale apical spot.

Inancalus peringueyt n. sp.

(Figs. 8, 8a.)

Allied to the European L. virens, but the face and front are much

darker, the second joint of the anterior tarsi is densely short black

haired on the postero-ventral surface and the wings are much less

extensively fuscous.

Length,8 mm. Male.—Face wide, brilliant deep green, but covered

with abundant brownish pollen which becomes paler along the orbits

and above. Front of the same colour but the pollen blackish brown

except below and above. Occiput grey pollinose, the bristles black,

with a few of those towards the lower edge of the eyes yellowish, the

sparse beard also yellowish. Palpi large, brown pollinose, with black

hairs. Antennae black; first joint bare above; third joint broader

than long, with a broadly rounded point, the arista inserted beyond

the middle of the joint, slender, about as long as an eye.

Mesonotum rather dull greenish, with four purplish-bronze vittae,

the median ones ending at the posterior third, the lateral abbreviated

at either end and interrupted at the suture; between these vittae a

more or less distinct violaceous one. Pleura greenish, grey pollinose.

Scutellum violaceous, its sides green; bearing six long marginal

bristles.

Legs blackish green, the femora and coxae grey pollinose, the tarsi

blackish. First joint of the anterior tarsus almost as long as the

remaining joints combined, slightly swollen at apex; second joint

short, not longer than the fourth, compressed and broadened (higher

than wide), with silvery reflection below, its anterior edge densely

beset with short black bristles which are curved at the apex; third

segment longer than the second, silvery on the lower surface, scarcely

widened. Claws of all the tarsi long and slender. Coxae with short,

fine yellowish pile. Legs short black haired except that the bases

of the femora have some fine pale hairs.

Wings hyaline, except the brownish areas shown in fig. 8. Squamae

and halteres yellow, the former yellow ciliate.

Abdomen bright deep green, the sides very densely pale grey pol-

linose, the broad posterior margin of each segment expanded anteriorly

in the middle, brown pollinose on more blackish ground. Sixth

segment green, the genitalia blackish, with long filamentous outer

lamellae. Abdomen yellow haired, the basal bristles black.

Female.—Similar in colour to the male but the front is less thickly

pollinose, the green ground colour being quite evident, and the middle

line of the abdomen and narrow bases of the segments are brown

pollinose. The wings are without maculation, the legs simple.

Length, 25mm. Male.—Thorax metallic greenin ground colour, the

abdomen blackish bronze with some yellow markings. Face very

narrow on the lower half, gradually increasing in width on the upper

half, wholly greyish pollinose. Front almost black, with a covering

of brownish pollen which almost conceals the ground colour. Occiput

dark metallic green covered above with brownish grey, below with

grey, pollen, the orbital cilia black, the hairs below short, fine, white.

Palpi small, subtriangular, pale yellowish. Antennae wholly black ;

third joint broader than long, subtriangular ; arista black, slender,

longer than the face.

Mesonotum brownish pollinose, leaving an almost bare vitta between

the acrostical and dorsal-central bristles, but the ground colour is

usually very apparent over the whole surface. Pleura grey pollinose.

Legs, including the coxae, yellow, only the middle coxae brownish

on the outer half. The posterior femora are brownish above on the

apical half, their tibiae brownish with yellow ventral surface, the

colours diffuse. The hind tarsi are wholly black, while the last four

joints of the anterior four and apex of the first joint are brownish, the

joints with darker apices. The hind tarsi are shaped as described in

the synopsis of the species, the third joint with a short, stout, apical

spine below on each side, the last two joints slender, and longer than

the second and third. The hair on the legs is all black and is quite

short for the most part ; on the hind tibiae it is moderately abundant

and subciliate as it forms a dorsal and anterior longer row from base

to apex, the anterior row being much longer and stronger and situated

below the middle. The first. three posterior tarsal joints bear rather

~ abundant short black hair.

Wings lightly infuscated, the posterior cross-vein slightly beyond

the middle of the wing and very slightly oblique; the fourth vein

approaches the third slightly, the slight forward curvature taking

place at the basal fourth of the last section. Squamae yellow, with

shghtly darker margin and black cilia. Halteres yellow.

Abdomen with the venter yellow on more than the basal half, the

sides of the first segment also yellowish. The second segment is some-

what variable in colour; normally it is brownish yellow, with a narrow

median vitta and the hind margin bronzed, the yellow colour concave

behind so that the dark colour again approaches the base at the sides,

but the pale colour may be much less extensive than described.

Genitalia normally hidden, the outer lamellae short, rather filamentous.

This species is represented in the collection by two males collected

at Durban, Natal, August 1920. I have also thirty-two specimens of

both sexes from Hast London, 17th and 23rd February 1924; male,

Port Shepstone, 21st August 1920. This latter lot were all collected

by Mr. H. K. Munro.

Sympycnus simplex n. sp.

of the greyish face which is slightly widened below and quite wide at

the antennae. Front evidently bronze green, covered with brownish

pollen. Occiput hidden. Palpi small, triangularly oval, yellow in

colour and bearing two or three yellow bristly hairs. Antennae black ;

third joint triangular, with rounded angles, not quite one-and-one-

fourth as long as wide ; arista sub-basal, black.

Thorax moderately greyish ? (or yellowish brown ?) pollinose,

probably leaving either two or four rather bare vittae, but it has been

wet and I am not able to make certain of this point. Pleura greyish

pollinose ; scutellum almost without pollen.

Legs, including the coxae, yellow, but the posterior four coxae are

brown on the anterior and exterior surfaces except on the apices ; the

posterior femora are brown on the upper surface, their tibiae tinged

with brown, the posterior tarsi wholly and the remaining tarsi except

the basal three-fifths of the first joint brown or black, the bases of the

joints of a slightly paler colour. The first joint of the front four tarsi

is almost as long as the remaining four joints combined, while the first

two joints of the hind tarsi are of almost equal length. Legs simple,

with normal black hairs. Coxae with pale pile. 2

410 Annals of the South African Museum.

Wings quite smoky, especially in front. The posterior cross-vein is

situated before the middle of the wing and is almost rectangular, the

fourth vein approaches the third slightly towards the wing margin,

its last section having a slight anterior angulation situated at about

the basal two-fifths. Squamae yellow, with black margin and cilia,

the halteres yellow.

Abdomen blackish bronze; genitalia small, concealed.

Female.—Differs only sexually; the face is less than one-fifth the

head width, slightly widened above and below. The third antennal

- jot is wider than long, rounded apically.

Type male, Oudebosch, Caledon Div., 1500 ft., January 1919,

collected by Mr. K. H. Barnard ; type female, same locality, December

1920, collected by Mr. R. M. Lightfoot.

Asyndetus Loew.

This genus is allied to Diaphorus Mg., but is readily distinguished

by the termination of the thickened portion of the costa at or slightly

beyond the tip of the third vein and the location of the cross-vein

beneath or before the apex of the first vein. Three species have been

recognised from Northern Africa, while there are apparently two un-

described species before me.

Asyndetus crassitarsis n. sp.

Length, 3 mm. Male.—Face about one-fifth the head width, green,

densely argenteous grey pollinose; front metallic green, almost

without pollen; occiput of the same colour, grey pollinose. Beard

white. Antennae wholly black, the third joint scarcely longer than

broad, its apex broadly rounded; arista almost as long as head

height, finely short pubescent. Palpi green, clothed with greyish

pollen and black hairs ; proboscis blackish.

Thorax and scutellum dark metallic green, the mesonotum with

bronze reflections and a darker bronze vitta on either side of the middle

line. Dorso-central bristles in four pairs, unusually strong; a single

weak bristle above the front coxae. Thorax greyish pollinose, the

dorsum only thinly so.

Legs metallic blackish green, greyish pollinose, black haired ; knees

and the anterior tibiae reddish. Anterior tarsi with the first joint

as long as the following three, slender, the fourth a little broadened and

flattened, the fifth slightly broader than the fourth, but little we

than wide, flattened.

The Dolichopodidae of the South African Museum. 411

Wings cinereous hyaline, the fourth vein evanescent opposite the

apex of the fifth ; there is an indication of a vein running to the apex

of the wing, but it lies considerably closer to the costa, its inner end

closer to the base of the wing than the apex of the fourth vein. The

posterior cross-vein is slightly oblique and joins the fourth vein slightly

beyond the tip of the first vein. Squamae and halteres pale yellowish,

the former white ciliate.

Abdomen dark green, with brassy reflections and moderately

clothed with greyish pollen, which is a little thicker at the sides.

Genitalia black, with four stout apical bristles, the lamellae small,

shining black, the genitalia elsewhere greyish pollinose. Hairs of the

abdomen all black.

Described from a single male from Kaapmuiden, Transvaal, 30th

October 1919, collected by Mr. R. W. E. Tucker.

Asyndetus indifferens n. sp.

Length, 3 mm. Female.—Very much like the preceding, but the

anterior tibiae are wholly dark, only the narrow knees reddish. The

palpi are black, broader and smaller, the antennae smaller. The only

differences, except in the wings and colour of the legs, are sexual.

The fourth vein is not so completely broken as there is an indication

of a junction of the fourth vein proper with the detached portion, the

inner end of which does not reach so close to the base of the wing,

and the vein itself is not as close to the costa as in crassitarsis.

A female labelled M’fongosi, Zululand, December 1916, collected

by Mr. W. E. Jones.

This may prove to be the female of crassitarsis but it does not seem

likely that itisso. Asa rule the legs of the females are paler coloured

than in the males, and for this reason I feel certain that it is a different

species. The two species may be readily separated as follows :—

A. Anterior tibiae wholly yellow, the tip but slightly darker Crassitarsis N. Sp.

AA. Anterior tibiae brown, the very narrow base reddish . indifferens n. sp.

Diaphorus Meigen.

undescribed species. The adults of this genus are not uncommon

about honey dew.

apices of the second and third segments and the base of the third

blackish, the whole of the fourth and fifth metallic green. Abdomen

thinly greyish-white pollinose on the disc, thickly so on the sides ; the

hair all black.

Male.—Length, 5°55 mm. The brown face is entirely obscured by

white pollen, the frontal triangle long, normally narrowly connected

with the vertical triangle (narrowly contiguous in some dried

specimens) ; pollen of frontal triangle similar to that on face, the

vertical triangle with more ochreous pollen. Occiput black, densely

grey pollinose. Antennae yellowish brown to blackish, the sub-

cordate third joint slightly wider than long, the slender brown arista

situated well above the middle of the joint. Palpi pale yellow, with

sparse black hairs; proboscis brownish red or brown, with white

hairs ; beard white.

The mesonotum is so densely ochreous-brownish pollinose as to

almost conceal the ground colour, the posterior slopes and side margins

in front of the wings with paler pollen. Pleura black, with green

reflections showing through the dense greyish pollen, the posterior

lower edge and a spot below the halteres yellow. Scutellum green,

its margin usually wholly pale yellow, the whole grey pollinose.

Coxae yellow, the middle ones almost all brown, the hairs black.

Legs yellow, the tarsi becoming brown from the tip of the first joint.

Front femora beneath on the anterior edge with a row of fine black

bristles which become shorter apically, the longest not over half as

long as the height of the femora, on the postero-ventral surface with

a much shorter row, but the basal bristle is stronger than any in the

anterior row ; in addition there is a row of longer black cilia on the

apical half of the posterior surface. The anterior tibiae bear on their

postero-ventral surface a row of short even cilia which are shorter

than the width of the tibiae. The apical joint of the front tarsus is

slightly widened and bears rather long hairs above ; their pulvilli are

brownish tinged, slightly longer than the fifth segment and clothed on

the edges with short silvery white pubescence. All the hairs on the

legs are black. The first joint of the anterior four tarsi is at least

twice as long as the second, the first two joints of the posterior ones of

practically equal length.

Wings greyish hyaline. Squamae and halteres yellow, the former

with black cilia.

First three abdominal segments yellowish or brownish yellow, the

venter of the fourth, brown, the narrow apices of the second and third

less greenish, the dorsum bronzed, the sides more densely greyish

pollinose than the dorsum. The hair is black, moderately long, the

bristles not well developed; the four bristles on the genitalia are

robust and almost as long as the fourth abdominal segment. Genitalia

brown, greyish pollinose, the appendages brownish.

The description of the female is from a specimen collected at Kamati

in the Eastern Transvaal. That of the male is from a specimen

from Pretoria and another from Hast London, both collected by

Mr. H. K. Munro. The male is not represented in the collection but

the description is given in order that it may be compared with the

following new species.

There is a single female collected by Mr. Lawrence at Zandemela,

Port. HE. Africa, in December 1923, which is either an undescribed

species, dasycnemus Loew, or an unusual form of brunneus. It has a

wide green vitta on the third abdominal segment. Unfortunately,

the abdomen has been partly eaten away.

Diaphorus lawrence new species.

The description of D. brunneus Loew applies well to this species,

with these exceptions :—

Lengths, the same. Male.—Antennae brownish red, paler beneath

(third joint missing, probably dark reddish) ; the middle tarsi lack

claws and. the pulvilli are greatly developed as on the front tarsi.

The apical abdominal segments are green.

Female.—Antennae wholly reddish, otherwise as in brunneus.

Described from one male and two females, Nyaka, Port. H. Africa,

February 1924, collected by Mr. R. F. Lawrence.

This species cannot be confused with any others so far known from

the region, as the red antennae at once distinguish the female, and

the enlarged pulvilli of the middle tarsi are characteristic of the male.

7 A Contribution to the Knowledge of the Genus Allodape, St. Farg. &

Serv. Order Hymenoptera ; Section Apidae (Anthophila).—By

Dr. H. Bravuns.

(With 2 Text-figures and Plates XI and XII.)

THis paper deals with the South African species of the genus Allodape.

We have now a fairly good knowledge of the Neuroptera, Orthoptera,

Hemiptera-Homoptera, Lepidoptera, and perhaps also of the Coleoptera

of the South African region ; but the study of the Hymenoptera, the

group of insects probably the most highly endowed with intelligence,

has so far been much neglected. The literature dealing with this

order is scattered through the scientific periodicals of the whole

world, and is therefore not readily accessible to the South African

student. For this reason monographs that recapitulate all that is

known on some part of the subject, including that which has not

been published as yet, become a necessity, and justify this contribution.

The types of the new species and the representatives of those

described by the earlier authors, both dealt with in this paper, are

deposited in the collections of the South African Museum.

BIOLOGY.

Entomologists who devote their attention to the study of the

Apidae have agreed to divide this family of Hymenoptera into two

sections—namely, Solitary Bees and Social Bees.

The first build their more or less rudimentary cells—or rather,

mostly partitions—in hollow stems, either scooped out by their own

exertions or found ready adapted for use, or they build their homes

beneath the soil. These they store with a certain amount of food,

and deposit an egg within or close to the cell or partition, leaving

the future larva to look after itself.

We know also of certain species that construct burrows or galleries

in the soil, so close to each other that a novice comes to the conclusion

that he has before him the result of the work of a single large family.

Among such species are certain Palearctic Andrena, American Halictus,

VOle Xi, PART 3. 28

418 Annals of the South African Museum.

and, in South Africa, Fidelia paradoxa, Friese, Anthophora circulata,

Fabr., and other kinds of Anthophora. Pseudo-colonies is the name

given to these agglomerations. ;

Individuals of Xylocopa caffra, L., a carpenter bee, which in South

Africa chisels its galleries in dry stumps, live at times so closely

together in the same piece of wood that the galleries are nearly con-

tiguous, but they never communicate. In spite of the vicinity of

the burrows, and the tendency to construct them close to each other,

any one builder or miner never interferes with the work of another.

Hach stays in its own burrow, and does not enter the house of its

neighbour unless by mistake. Let us go a step further. We know

that members of a few species of Halictus and Nomisa—probably

more will be found to do so—associate to dig together a gallery with

only one entrance. Several females use this entrance and the same

gallery, but they burrow sideways to construct their small solitary

partitions for the storage of food and deposition of the egg.

The second section, a numerous one, comprises the social bees

which live together in more or less large numbers of individuals,

building, as in the case of the common honey-bee, most elaborate

structures of cells; in most cases feeding their larvae, tending them

until they are near the adult stage, and closing their cells for the

pupal stage.

The old authors considered the species of the genus Allodape to

be mostly parasites; and from the time of Lepeletier St. Fargeau

we find them quoted in hymenopterous literature as being parasites

or messmates. This mistake is not easily explained, because the

species of Allodape bear on the legs a distinct collecting apparatus

of hair-brushes. They are in fact true social bees, although their

colonies are as primitive as can be. There is no building of cells,

no shrouding of the brood whatsoever. The female excavates a

tunnel into the dry stem of iridaceous plants, Iris, Rosa, Aloe, Rubus,

amaryllid plants, etc., or any other plant with a soft pith ; it removes

the latter entirely, and the nest is then ready. I believe that in most

cases labour is not even involved. They as often as not use the

stems previously hollowed out by Ceratina bees, or perhaps Diploptera

wasps. Some of the smaller species utilise the galleries made by

Coleoptera in dead logs or poles, or again the long thorns of mimosa

trees. In the plains of the Karroo, where suitable plants are not as

common as in other parts of South Africa, some of the small species

even nest in the ground, in the steep sides of dry rivers and “ sluits,”

and even in the walls of houses. So, for instance, does the widely

distributed Allodape pringleir, Cam.; but this nesting in the ground

is comparatively rare.

The colony is founded by the female alone at any season of the

year. It is, of course, clearly established that at higher altitudes the

seasonal temperature and the want of flowers must impede or hinder

the continual gathering of food, but there is no hibernation. A warm

sunny day finds the bee out of doors, even in the middle of the winter

season. Certain plants flower only in the cold or winter season, as,

for instance, the Hricaceae, some Aloes, Lycium, and others. Some-

thing is always to be had. After excavating the stem to a convenient

depth, or putting the last touch to the ready-made gallery, according

to her taste, the female deposits the egg at the more or less rounded

bottom of the hollow part. The egg is of large size in comparison

with the size of the bee, and of kidney shape. As soon as the larva

is hatched the mother commences feeding it. The egg or eggs that

will hatch last are always to be found at the bottom of the cavity ;

above them are to be found the younger larvae, then the more advanced

ones, and towards the entrance are the pupae. Sometimes, however,

this disposition will be found to be disturbed. The mother in carrying

food to the young larva at the lower part of the cavity must perforce

constantly pass the pupae and larger larvae, and may thereby slightly

disturb the above-mentioned order, but this occurs rarely.

A special worker class, such as we find in the genera Apis, Bombus,

Trigona, and Melipona—that is to say, a more or less crippled female,

is not to be found in Allodape. All females are fertile, and, as far as

known, take a share in breeding and feeding the larvae. In all pro-

bability the young females, after fertilisation, constantly found new

nests. But they return for a considerable time to their original home

and there feed the foster brother- and sister-larvae. The males return

to the nest as well, and the latter when opened in the evening are

found to be crowded with a population of both sexes. The old mother

bee is easily recognised through her tattered wings and other signs

of hard work and old age, but otherwise there is little difference in

size between herself and her female progeny.

There are three types of larvae in the genus Allodape, corresponding

with three methods of feeding. In the first case the larva is provided

on the thoracic part of the body with a pair of movable and contractile

fleshy protuberances which we will call, in accordance with their

function, arms. The larva of A. ceratinoides, Grib., is here figured as

a conspicuous example of this form. These arms enable the larva to

retain firmly the small morsel of food deposited between them by the

420 Annals of the South African Museum.

mother bee, who feeds in this way a number of larvae at one visit.

They close these arm-like processes round the morsel of food, and are

thus able to retain their hold of it until it is devoured. On opening

the nest shortly after the entrance of the mother bee one finds a number

of larvae supplied in this manner with food particles, and busy feeding.

Nearly all species of large size, in

fact the great majority of the

South African species, belong to

the section the larvae of which

are of this type. I find it im-

possible to describe in detail the

structural forms of the larva

within the compass of this paper.

I have noticed that the form of

the integumentary appendages

differs in different species, and

even alters in appearance in the

different stages of development

following the consecutive castings

of skin. Therefore the description

of the larvae of different species

had better be kept over for a

special paper dealing with a sub-

b, Head of the same (p. pseudo- ject worthy of careful and de-

podion): tailed study.

The second type of larva is illustrated by that of A. pringlev,

Cameron. It is easily seen from this figure that it is altogether

different from the first. The egg is no longer lying loose at the

bottom of the cavity, but a row of eggs (up to ten or more in number)

is fastened, perpendicularly, probably by an agglutinous substance,

by the lower polar end to the walls of the hollowed stems, and arranged

in a more or less spiral curve. The larvae are provided with a great

number of short, fleshy, and contractile appendages disposed round

the segments. Friese uses the term Pseudopodion for these append-

ages. By the aid of these fleshy protuberances the larvae are able

to keep their position in the same level of the lumen of the gallery.

By pressing these protuberances against the rugosities of the walls,

and also against the bodies of their neighbours, they maintain the

position of the body in the gallery in such a way that the apical end

of the larvae and the heads of the same are each at the same level.

It follows that the hatching of the larvae must take place, approxi-

mately, at the same time. It is probable that the bee lays and

fastens the row of eggs in rapid succession. The feeding of the larvae

is accomplished in the following manner. The mother bee deposits

the food in the space left between the heads of the larvae so that

they can all feed at the same time from the same food supply.. The

pupae and the larvae after the last casting of skin are found near the

entrance, and the agglomeration of larvae still feeding are below them,

nearer to the bottom.

In principle the manner in which the larvae are fed in the two

typical instances here given is really the same. The larvae are not

fed directly by the mother bee, nor by regurgitation, but they are

fitted with integumentary organs for holding the food near the buccal

parts, and also in one case for clinging to the walls of the cavity.

They use the food supply in a way similar to that which that eminent

observer of ants and their life-history, Professor W. M. Wheeler, has

shown us so clearly to happen in the case of Ponerine Ant larvae. It

may be stated, however, that the larva casts off the integumentary

422 Annals of the South African Museum.

appendages at the last moult leading to the pro-pupal stage, when it

has already assumed the maggot-like appearance of the usual bee

larva.

The third method of feeding the larva is, in comparison with the

two already described, the most interesting and the most important.

I have only recently observed it in the case of a small species making

its nest in the Karroo plains in the dry stems of a native asparagus.

There is no doubt about the result of my observations since I have

come across about a dozen colonies.

In this species the mother bee carries in food for one larva only

at atime. As in the first type, she first lays the egg, which in com-

parison with her own size is enormous, being almost equal to one-

third of her own bulk. After the oviposition she brings in enough

food to last for the larva until it reaches the pupal stage. The volume

of this pollen mass is about the same as we find in cases of solitary

bees, as for instance in any of the partitions of the nest of a Ceratina

species of the same size. It is quite sufficient for one larva. If we

open the nest we find one larva clinging to a pollen mass, another to

the next one, and so on. On the top of all is a fresh egg, and above

it a pollen mass which the bee is about to completes. When several

larvae are present the one on the bottom is the most advanced.

I found the colonies provided in this manner in all stages of growth.

The external appearance of the larva is also different from that of the

two first-described types. The larva clings closely and broadly with

its very flat ventral surface to the food mass. Only two comparatively

small and inconspicuous fleshy protuberances, the anterior larger than

the posterior, are to be seen on each side of the larva. It will be

necessary to observe more closely the habits of this species. More

will probably be found providing their larvae in this manner.

There is only one difference separating the economy of this bee

from that of the general type of solitary bees, namely, that in this

instance there is no partition between two adjacent larvae and their

store of food.

This point is of great importance, and should be thoroughly grasped.

All other solitary bees provide first the food, then lay the egg on it,

and close the cell or partition, proceeding after this with another

partition resting on the closed one. In the case of this Allodape the

process is the same, except that the egg is first laid, then a sufficiency

of provender carried in for the future larva; another egg is laid

above the first, food brought in for the same; and soon. But there

is no partition separating the larvae and their food as in the case

A Contribution to the Knowledge of the Genus Allodape. 423

of all other solitary bees; and the gallery is not closed after the last

egg has been provisioned with the required food.

The reason for this method of oviposition may perhaps be explained

as follows. As mentioned before, the egg is very voluminous in

comparison to the size of the mother bee. It is hardly credible that

a small bee should lay eggs one-third her own size in rapid succession.

Such eggs take time to mature in so small an ovarium, and cannot there-

fore be laid at short intervals. .Owing to this, the bee has time

enough to bring in food sufficient to feed each larva till the pupal

stage is reached.

In the first type of oviposition and food storage, it is true, as already

stated, that the egg is also very large, but we do not know the time

required for the completion of the oviposition. In the second type,

where numerous eggs are fastened to the walls of the gallery, the size

of these eggs is small, and accords with the size of the mother bee.

From the description of their position it is evident that they must

be laid in rapid succession in order to allow all the hatched larvae

to feed from the same food supply, and at the same time.

It is plain that more observations are needed to complete the

knowledge of the economy of this most interesting genus of solitary

bees, but the few facts now recorded cannot but be of value as throw-

ing a new light on the evolution of the foundation of colonies among

Apidae.

DISTRIBUTION.

The species of Allodape are distributed over tropical and sub-

tropical Africa. They occur also in India and Australia. In tropical

Africa there is an exceedingly large number of species, but owing to

the small size of most of them, as well as to the difficulty inherent

to identification of the species which are not bred out of the nest, little

attention has been given them by hymenopterologists.

They abound in the western, eastern, and southern parts of South

Africa, chiefly on the coastal belt, where abundance of flowers appar-

ently favours their occurrence. In the grassy plains of the Orange

Free State and the Transvaal they are rare. In the Karroo plains

of Cape Colony they are numerous. Near Port Elizabeth and near

Cape Town I found them nesting in great numbers in the dry stems

of liliaceous, iridaceous, and amaryllidaceous plants and others.

I also found numerous species in the tropical parts of West and

Hast Africa.

Although the number of African kinds must be very large, only

424 Annals of the South African Museum.

a comparatively small number of species has been described, and,

unfortunately, from single captured specimens. The descriptions are

on that account very insufficient and unreliable. The females of the

smaller species are very difficult to separate owing to the absence of

good structural characters. Although the colour and the facial

markings of many kinds seem to be fairly constant, and must be

taken into account for the purpose of differentiation, in other species

_ these characters are no longer constant. For this reason I have only

made use of them when other distinct differences failed. Thus some

parts of the body such as the coxae, trochanters, and femora of the

males, the ultimate tergites and sternites, and also the facial surface

of the females afford in certain species useful structural distinctions.

PARASITES OR MESS-MATES.

I have described the only parasite hitherto known to be found in

the nest of Allodape bees: Hucondylops konowi, Br. (Friese’s Die

Bienen Afrikas). I met with this singular bee in the nests of

Allodape elizabethana, Br., and A. paradoxa, Br. Near Willowmore

I discovered it also in the nest of Allodape pringler, Cam., and Friese

received it from the northern parts of South Africa. It 1s, however,

not yet clear if this bee is a true parasite of the Allodape bee, or whether

its relations to the latter are those of a mess-mate, as in the case of

Bombus and Psithyrus. It is to be hoped that other species of Hucon-

dylops, perhaps larger ones, may be found with the larger species

of Allodape.

DESCRIPTION.

It is too early to attempt giving the description of the species

occurring in the southern part of the African continent, and I have

therefore restricted my task to that of such as I have taken from the

nest, or bred from the nest. This paper cannot be more than the

prodromus of a monograph which has yet to be written. I have

examined a few types, but can attach little value to the descriptions

of Cameron, Vachal, and others. Cameron described a species of

Allodape, of which I saw the type, as a Prosopis ; probably he has

done the same for more species of the first genus. Owing to the

inadequacy of the literature I have been compelled to describe most

of the species in my collection, and others, as new ; but as the number

of existing descriptions of Allodape is small, the task of clearing the

synonymy will not be a heavy one for the hymenopterologist who

A Contribution to the Knowledge of the Genus Allodape. 425

will ultimately undertake it. Friese in his Die Bienen Afrikas

(Schultze’s Reise im Westl. und Zentral. Siidafrika) enumerates thirty-

one African species. My own research leads me to the conclusion

that this is only a “ drop in a glass of water.”

The tropical Allodape seem to be very interesting, and are made

conspicuous by the structure of the males. I hope that this paper

will lead to a more careful observation of the habits of this interesting

genus. I hold that to describe species of this genus from single |

captured specimens will only produce endless confusion and lay an

almost unsupportable burden on those who undertake further work

in connection with this genus of bees.

The genus Allodape, St. Farg. & Serv., is founded by these authors

on Allodape rufogastra, Lep., which has thus to be considered as the

“Genotype.” The characters assigned to the genus, when trans-

lated, are as follows: “ Maxillary palps four-jointed ; labial palps

four-jointed. Ocelli disposed in a triangle. Scutellum bluntly

raised ; tibiae of the intermediate legs with one simple spur at apex,

those of the hind legs with two simple spurs. Radial cell of the fore-

wing oval, narrowed from middle to apex, with a small appendix ;

three cubital cells, the first larger than the second, which is narrowed

towards the radial, and receiving the two recurrent nervures; the

third cell reaches the apex of the wing. ‘Tarsal claws bifid.”

St. Fargeau adds that he does not know on what genus the species

(A. abdominale, St. Farg., A. rufogastra, Lep. & Serv.) is a parasite.

Taschenberg, in his synoptic table of bees, gives the following generic

description of the genus Allodape, of which I here give the translation :

“ Maxillary palps dimorphic. Genae small. Labrum short, convex,

hardly visible. Mandibles bi-dentate, their base reaching the edge of

the eye. Ocelli disposed in an acute triangle. Antennae filiform,

with the second joint short. Radial cell lanceolate, narrowed from

the middle towards the apex. Two cubital cells, the first about twice

as long as the second, the latter arcuate outwardly, only slightly

narrowed on the upper side, and receiving both the recurrent nervures,

the first of which is further removed from the anterior corner than

the second from the posterior. Median nervure arcuate. Basal lobe

of hind wings about the length of the submedian cell. Body fairly

smooth, elongated. Thorax ovate; abdomen elliptical, the last

segments depressed towards the apex in the female, but as acuminate

as in the female of Ceratina ; legs pilose as in the female of Ceratina,

and without genicular scale.”

426 Annals of the South African Museum.

Gen. ALLODAPE, Lepell.

Encyl. method. Ins., x, 1825, p. 18.

The genus Allodape is clearly related to Hxoneura and Ceratina.

The former is an Australian genus, of which the habits are unknown.

Ceratina larvae are long and parallel in shape, but have on the sides

of the segments conspicuous fleshy protuberances, which are of no

actual use because they are immovable; but their presence seems

to indicate a near relationship to Allodape.

The shape of the 2 and 3 respectively is very similar in both these

genera. In each the female has the apical end of the abdomen sharply

pointed, whereas the apical end of the male is convex and tumid, the

last tergites curving towards the ventral surface. On the other hand

the 2 of Allodape has a very characteristic structure of the abdominal

segments. The tergites overlap each other extensively towards the

ventral surface, and are therefore much wider than the corresponding

sternites. The apical three or four tergites are in all species distinctly

flattened, the flatness increasing towards the tip of abdomen. This

structure of the abdomen enables the bee—as it does in the genus

Megachile—to curve the abdomen upwards to an unusual extent.

The sting is therefore also directed upwards. This peculiarity is of

biological value. When the stem inhabited by Allodape is disturbed,

one of the females moves backwards to the entrance, and closes it

completely by means of the flattened surface of the last tergite, and

the sting directed upwards defends the entrance very effectively.

The surface of the flattened tergites is as a rule very roughly sculptured.

The first tergite is nearly always hollowed at the base, and with two

rounded, semi-lunar, raised, and not very conspicuous tubercles, one

on each side. The tongue is very long, and although the species of

Allodape visit all sorts of flowers, they prefer those that have a tubular

corolla, such as the Labiatae, Solanum, Lycium, and others. The

clypeus in the female of all species of Allodape is conspicuously

elongated in front. The mandibles of the female are short and

broad, triangular in form, and very powerful, so as to be able

to remove the pith of the stems inhabited by these bees. The spurs

of the hind legs are very long, nearly half the length of the metatarsus.

In the male sex of a large section of the South African species the

trochanter of the hind legs bears two dentiform protuberances, while

in another, but smaller, section of South African species the tro-

chanters are simple. This character may perhaps lead to a morpho-

logical division of the South African species into two distinct sections.

A Contribution to the Knowledge of the Genus Allodape. 427

The livery is much alike. The colour of the head and thorax is

mostly black, of the abdomen wholly or in part black or red. The

face in a large section of the species has in the female three longitudinal

lines of white or yellow, one running longitudinally along the middle

of the clypeus, the other two along the inner part of the orbits. The

extent of these markings is very variable, and cannot be relied upon

as stable. A second section has on the clypeus a T-shaped mark of

variable size. In all these species the males have generally a totally

white or yellow clypeus. Sometimes the face is completely black with-

out white or yellow markings. The scutellum has in some species a

white or yellow transverse band, which is variable in size, and may dis-

appear altogether in the same species. The same is the case with

the white or yellow bands and spots on the pronotum, the squamae

of the fore-wings, and the humeral tubercles of the shoulder. The

external border of the eyes at the tempora bears in the majority of

species a yellow or white line, more or less variable in size and extension.

I have not yet seen any species with yellow or white markings on the

abdomen or other parts of the body. It is very difficult as a rule to

separate specifically the smaller black species. Only the observation

of the nest will give a clue in their case.

Allodape angulata, new sp.

2. Black; a dull yellow, narrow, median longitudinal line reaching

from the frontal margin of the clypeus to the oral margin, but some-

times obliterated or even absent. The inner orbit is of the same

colour, broader in the lower part, narrowed towards the vertex,

neither reaching to the base of the eyes nor to the vertical margin

of the same. The outer orbit at the tempora has a narrow line of

the same colour obliterated above and below.

$. Black. The clypeus is bright yellow with only a small black

anterior margin. The yellow colour is sometimes not sharply defined

towards the oral black edge. In some of my specimens I find no

trace of a yellow line at the tempora. In the lower part of the face

between the clypeus and the lower part of the inner orbit is a some-

what triangular large patch of yellow, rounded towards the clypeus

and straight along the inner orbit, but not reaching higher than the

frontal margin of the clypeus.

°. Mandibles shiny, short, nearly triangular in shape, smooth, with

a few scattered punctures and a long narrow groove along the lower

edge, bi-dentate; genae—v.e. the space between the mandibular

joint and the lower pole of the eyes—hardly conspicuous, half as

wide as the 3rd antennal joint. Labrum semicircular, very broadly

and roughly punctured, the punctures variolate ; clypeus somewhat

elongate in the oral part, oral margin nearly straight and slightly

sinuate inthe middle. The lower lateral edges of the clypeus carinate ;

the carina, reaching the base of the mandibles, curves towards the

inner orbit, reaches the inner margin of the eyes about the middle

of the length, runs close to the eyes up to the frontal part, and curves

towards the lower stemma, where it reaches the carinae, which enclose

the lower stemma. Clypeus coarsely punctured in the upper part and

near the edges, smooth longitudinally in the middle. Sides of the

face coarsely punctured, more scantily so towards the eyes; frons

between antennae more finely and closely punctured than the sides.

A carina reaches from each of the upper stemmata towards the middle

line, enclosing the lower stemma; below the latter the carinae are

angularly broken and run narrowly together towards the clypeus,

uniting immediately above the point of insertion of the antennae.

Vertex finely punctured between the stemmata, almost smooth

between the latter and the eyes, and bearing only a few setigerous

punctures. ‘Tempora broad, sparsely punctured, shining. Dorsulum

of the mesothorax broadly smooth and shining, without punctures in

the middle, coarsely but sparsely punctured all round the edges ;

a finely impressed longitudinal line reaches in the middle from the

anterior margin of the mesothorax to the punctured belt in front

of the scutellum. This as well as the metanotum (postscutellum)

sparsely and coarsely punctured. The cordate area of the median seg-

ment is circularly grooved in the centre and there dulled by a coria-

ceous sculpture, the sides being sparsely and finely punctured. The

sides of the median segment are finely punctured. The meso-

pleurae are sparsely and coarsely punctured throughout; the meta-

pleurae smooth, shiny, and impunctate. Tergites of the abdomen

strongly punctured, the punctures aciculate towards the end of the

abdomen; the first near the hind margins roundly raised on both

sides, the hind margins narrowly smooth, those of the 4th and 5th

weakly carinate. The last tergite (6th) ends in the middle in a sharp

mucro, on each side of which the margin is angular; this tergite is

concave in the middle, the mucro and the angular margin being

recurved. The tergites are depressed towards the apex of the

abdomen, as in all species of the genus Allodape, the sternites of the

abdomen are more or less smooth at the basal, and coarsely punctured

in the apical part. The 6th or last sternite is in the shape of an

equilateral, the sharply pointed apex of which reaches that of the

dorsal mucro; the segment has a median longitudinal smooth line.

The pubescence of the female is distributed as follows :—Mandibles,

labrum, clypeus and face with scanty and short ferruginous hairs.

The hairs are longer on the vertex, very scanty on the tempora. The

sides and margins of the mesothorax, scutellum, mesonotum, and sides

of the median segment bear a pale fulvous pubescence; the meso-

pleurae and sterna, the coxae and upper side of femora are covered

with the same pale fulvous pubescence. The tubercles (scapulae)

have a thick fringe of appressed hairs on the apical margin. The

tergites bear a short grey pubescence intermixed with short black

bristles on the depressed segments; long ferruginous hairs cover

scantily the sides of the abdomen and the posterior parts of the

sternites, and are very conspicuous on the last sternite. The under-

side of the femora is smooth, shiny, hairless and concave so as to

admit the tibiae. The colour of the hair-brushes of the middle and

hind tibiae and metatarsi is bright ferruginous. The wings are

smoky, iridescent, with brown nervures. The stigma is long, and

light brown in the middle.

Length.—13-16 mm.

3. The anterior margin of the clypeus is broadly truncate and

straight. There is hardly a trace of the facial carinae in the lower

face, but the two fine carinae from the lower stemma are parallel

and very narrow; the frontal stemma is situated in a shallow im-

pression enclosed by rounded walls. The genae (spaces between

mandibles and eyes) are broader than in the 9, as broad as the length

of the third joint of the antennae. The punctation of the body is

much the same as in the 9, but finer. The smooth margins of the

2nd to 5th tergites are pale testaceous. The last tergite and sternite

are rounded. The fringe of the apical segments is fulvous. The

metatarsi and tarsi of all the legs are light ferruginous in colour with

a fulvous pubescence, the hind trochanters have each five short blunt

teeth on the inner edge; the basal edge of the hind femur is bluntly

triangular.

Length.—13-16 mm.

This is one of the largest of the South African species. The Q is

readily recognised by the peculiar shape of the last tergite of the

abdomen. Allodape paradoxa, Brauns, has a similarly shaped dorsal

segment, but is only half the size of A. angulata. The g can be easily

mistaken for the same sex of Allodape clypeata, Brauns, and is of the

same size.

430 Annals of the South African Museum.

I am not quite sure whether Allodape angulata is the Allodape

mucronata, Smith. In fact, the description of the latter agrees so

very well with my species that I believe it to be the same. However,

the colour of the abdomen is different in Smith’s species. It may be

that he described his species from an immature example. The

species seems to be restricted to the western and south-western parts

of the Cape Province. The habitats known to me are :—Cape Pro-

vince: Uniondale (December) ; Willowmore (October) ; Cape Town

(December). I found the nest inhabited by both sexes in the dry

inflorescence stems of an iridaceous plant at Uniondale.

a more or less distinct longitudinal line of lurid yellow in the centre

of the clypeus.

g. Black, with the face black or with a more or less broad longi-

tudinal median yellow line on the clypeus, sometimes dilated above

or below.

©. Mandibles very scantily punctured. Genae as wide as the length

of the pedicel of the antennae. Labrum convex, with a few large

punctures. Clypeus somewhat elongate, the oral margin truncate in

the middle, sparsely punctured, as is also the lower part of the face

between the clypeus and the orbit ; separated from the frons on each

side by an impressed line, which becomes grooved towards the oral

margin of the clypeus. The clypeus as well as the face has an adipose

sheen due to an extremely fine unctuous punctation. The twin keel

between the antennae is distinct, and reaching neither the clypeus

nor the lower stemma ; the latter situated in a groove with rounded

walls. <A fine impressed line runs towards the keel between the anten-

nae. Frons and temples shiny with a few fine scattered punctures ;

mesonotum with a few scattered punctures in the middle, more closely

punctate towards the sides and the scutellum. The latter is dull,

sparsely punctured, and like the adjoining belt of mesonotum extremely

finely shagreened. Mesonotum with a finely impressed line in the

middle and on each side. The cordate area of the median segment

is closely punctured, opaque, well defined, and coriaceous. The sides

of the median segment are shining. Mesopleurae shining, sparsely

punctured, each puncture bearing a hair. First tergite with a rounded

tubercle on each side, hardly punctured, but like the following tergites

extremely finely shagreened. The other tergites are very finely but

sparsely punctured. The shagreened sculpture becomes closer and

duller towards the apex of the abdomen. Last tergite concave on

each side of the hind margin, angularly produced in the middle, and

obtusely and roundly pointed, the extreme point and the side angles

being recurved. ‘The sternites are shining, glossy at the basal part,

sparsely punctured and setigerous in the apical. The last sternite

is trapezoidal, ending in two sharp points, which are curved upwards,

covering and overlapping the obtusely pointed last tergite; last

sternite sinuate between the points.

The pilosity of this species is scanty on the oral parts, vertex,

scutellum, pleurae, sides of abdomen, and basal parts of the legs, and

is of a greyish-white colour. The scopa of the hind legs is greyish-

white, the hairs of the median and hind metatarsus ferruginous.

Length.—6-7 mm.

3. The punctation of the male is much the same as that of the

female. The main character separating this sex from the other small

black species of the genus is the form of the hind femora, which are

broadly swollen and enlarged, and rounded at the basal angle. The

hind trochanters are not spinose; the hind tibiae are somewhat

curved, and enlarged towards the apex; the last tergite is broadly

rounded, and hardly sinuate in the middle. Fringe of the top of the

abdomen ferruginous. Wings hyaline with iridescent sheen. Stigma

and veins piceous. Pubescence greyish.

Length.—5-—6 mm.

This species is not common. I found it in August nesting at Port

Elizabeth in dry inflorescence stalks of Liliaceae, and also at the same

time of the year at Willowmore. The female is easily recognised by

the shape of the last abdominal segment; the male by the form of

the hind femora.

Labrum trapezoidal, deeply and broadly punctured, punctures

umbilicate. Clypeus produced, oral margin truncate with a few

coarse punctures near the margin. The clypeus as well as the sides

of the face evenly but not closely punctured, punctures setigerous.

The keel between the eyes is distinct. Vertex on both sides smooth.

Occiput more closely punctured, tempora shining, bearing distinct

but scattered punctures. Mesothorax smooth in the middle, im-

punctate, the frontal, lateral and hind parts closely and distinctly

punctured. In the middle and on the sides are three abbreviated

impressed lines. Scutellum closely and more finely punctured than

the mesothorax. Cordate area of the median segment ill-defined,

not distinctly separated from the rest of the median segment, smooth

and without punctures. Tergites aciculate from the second one and

more closely towards the end of abdomen; the punctures setigerous.

Sternites sharply punctured in the apical parts; the last is triangular,

with a triangular smooth space at the base, and sends a fine carinula

to the apex. The pubescence is rich and on some parts villose. The

vertex, pleurae and pectus, the margins of the mesothorax and the

sides of the median segment, are densely clothed with a bright

brown-yellow villosity with a golden sheen in fresh specimens.

The metatarsi and the brush of the hind tibiae and tarsi are bright

ferruginous with a golden sheen. A conspicuous short velvety brush

at the end of the hind tibiae is bright purple. This brush is situated

on the external side of the tibiae, and reaches from the apex to past

the middle. The pubescence of the ventral part, sides, and apex of

the abdomen is scantier, but long and whitish-grey.

$. Sculpture and pubescence are much the same asin the?. Labrum

quadrangular, smooth with a few scattered punctures. Basal part of

clypeus smooth, hardly punctured. The punctures of the apical

clypeus large and dispersed. The hind margins of the last three or

four tergites are somewhat raised, smooth, the last rounded. The

lower angles of the hind femora are sharply triangular.

The trochanter is provided with a sharp curved tooth on the inner

base and a nodiform process towards the base of the femur. The

fringe on the end of the abdomen is ferruginous. The pubescence

of the legs is of the same bright colour, but not so dense and long as

in the female. The purple brush of the external edge of the hind

tibiae is conspicuous, but shorter than in the 9.

this species is the one described by Gribodo. His description is good,

and the habitat of the type, Port Elizabeth, is the same as for most

of my specimens. It is common along the eastern coast of the Cape

Province, where it seems to have a wide range. I found it at Port

Elizabeth, George, Knysna, Uniondale, etc. It breeds all the year

round in the stem of any plant with a soft pith. I found it nesting

in Rubus, and the inflorescence stalks of liiaceous and amaryllidaceous

plants. The main character of the 9 is the size, villosity, and colour.

When the colour of the latter is faded it can easily be confounded with

related species. The male will be recognised best by the form of the

hind trochanter and the angulated base of the hind femur.

I have in the past sent the species to correspondents under the

mm litt. name A. villosa.

Allodape hirsuta, new sp.

2. Black, with a broad yellow longitudinal line in the middle of the

clypeus. The inner orbit, the posterior margin of the eyes on the

tempora, and a broad transverse band on the scutellum, somewhat

bisinuate at the base, are also yellow. Stigma of the fore-wings

brown.

$. Black, the clypeus totally yellow, otherwise with the same yellow

markings as the 9. The inner orbit is more broadly yellow at the

base than on the upper part.

The sculpture and punctation of this species is exactly the same

as in A. ceratinoides, Gribodo. The two species are very closely

related, but A. hirsuta is of much larger size, and the coloration is

constant. The dense villosity of the body and legs is alike in the two

species, as well as the bright colour and sheen of the pubescence,

including the purple brush of the hind tibiae.

In the g the main characters are also the same as in the same sex

of A. ceratinoides. The base of the hind femur is sharply and tri-

angularly produced, and the teeth and protuberances of the trochanter

are shaped as in ceratinotdes.

Length.—@ 12-15 mm., g 12-14 mm.

I found this species nesting at Port Elizabeth under the same

conditions and in the same plants as A. ceratinoides, but in nests

always separated from each other, thus showing that hirsuta is a

distinct species. I found it also near Knysna. The species seems to

inhabit the east coast of the Cape Province, having thus the same

range as A. ceratinoides. It breeds all the year round.

8. On some South African Ichneumonidae in the Collection of the

South African Museum.—By CLaupe Morey, F.Z.8., F.E.S.,

Memb. Soc. Entom. de France, etc. Part III.

RECENT consignments of Parasitic Hymenoptera have enabled me

again to extend our still limited knowledge of the species occurring in

Southern Africa, and to supplement my former studies upon them,

contained in the Revision of Ichneumonidae and in these Annals,

Vol. XV, pp. 353-400, and Vol. XVII, pp. 191-229. As before, a

large proportion of the species enumerated is from the interesting

district of Zululand, where the insect fauna of the east-central regions

merges with that of the more southern parts of the Continent. The

lesser proportion of new kinds in the present paper may, I think, be

taken as indicative that our knowledge is at length approaching,

though still far distant from, perfection. The European Continent

and America to the north of Mexico are the only parts of the globe

of which we yet possess anything like full accounts of Ichneumonidae :

a first volume of the Indian species was published in 1913, and a second

awaits nothing but official sanction for its appearance. South Africa

may now be regarded as the next forward in this respect, for nothing

but isolated accounts have yet been put forth by other countries.

The Swedes, however, who have given us a good lead since Holmgren

began to publish in 1855, are now contributing much literature on

the group. The types of the new species mentioned in the following

list are in the South African Museum.

Epyoppa tricolor, sp. nov.

A stout red species with the mandibular base, frontal and temporal

orbits, small callosity before radices, postscutellum, apical margin

of all the segments except third and centre of second, coxae except

centre of hind ones beneath, anterior tibiae externally and apices

of their femora, pure white; tegulae, fourth and following segments,

coxae, black. Metathorax distinctly punctate, with areola strongly

transverse and costulae conspicuous ; face not sulcate ; clypeal tooth

small but acute. Length, 10mm. Female only. |

This species agrees with the Nigerian #. rubricata, Morl., in its

hyaline wings, rufescent mesonotum, antennae, and legs; though

differing in the white postscutellum, red metathorax, flagellar apices

and abdominal base, as well as in the above sculpture. The. type

C. striata though stouter, with the whole sculpture coarser and meta-

thoracic areae more definite.

* It must be noted that Szepligeti’s paper upon the Ichnewmonidae of the

Kilimandjaro-Meru Expedition was not published until 1910. The distribution

of authcr’s separata before that date has led to some confusion ; these bear the

date of printing—not of publication—“ August 1907” ; and it has been variously

quoted as 1907 by Roman in the Entomologisk Tidskrift of 1910, and as 1908 in

the Zoological Record. It must be retained as 1910. This distribution before

publication is a reprehensible practice, and some of Koman’s names are in danger

of taking priority over those he criticises. Much of the material collected by this

Expedition yet remains to be worked, though all the larger museums of Hurope

contain unnamed African Ichneumonidae; and not the least is the mass now

lying in the British Museum, consisting of thousands of specimens from all parts

of the Ethiopian continent.—CLAUDE MORLEY.

Essential Characters.—Body not metallic ; upper basal nervure not

antefurcal; metathoracic spiracles elongate, never ovate; clypeus

not reflexed; alar areolet entire or sub-entire; frons not cornute,

at most centrally carinate; mandibular teeth of sub-equal length,

apophyses small but usually distinct ; metanotum bitranscarinate.

The forty species already standing under this genus in Africa are by

no means homogeneous and need revision, which is very dangerous

work in the absence of types. Especially with Goryphus are they

mixed. The more southern kinds may be thus roughly tabulated :

Types of both sexes show M. elizabethae, Cam., to be the 9 of

M. albipalpis, Cam.; the distinctions of the table (Ann. 8. Afr. Mus.,

v, 1906, p. 145) are very slight and not specific. MM. mameticus, Cam.

(Records Albany Mus., 1, 1905, p. 250)=M. onetl, Cam. (lab. cit., 1,

1904, p. 143), and M. basimacula, Cam. (loc. cit., i, 1905, p. 249), 1s its 3.

M. juvenilis, Tosq. (Mem. Soc. Ent. Belg., v, 1896, p. 214, 2), must

be called M. ensator, since Roman (Zool. Bidr. fr. Uppsala, i, 1912,

p- 253) has proved Ichneumon ensator, Thunberg. (Mem. Acad. Sc.

Petrograd, vii, 1822, p. 259, and ix, 1824, p. 306) to be synonymous.

M. laevifrons, Cam., and M. lightfooti, Cam., of 1906, are both

Stenaraeus. M. parvidens, Cam., 1906, is a Goryphus, and I have

seen the type.

Mesostenus edenticlypeus, sp. nov.

2. A somewhat slender, rich testaceous, dull species with the head,

antennae, onychii, disc of sixth and seventh segments, and terebra

deep black; face, mouth, cheeks, all the orbits broadly, flagellar

band and second to base of fourth hind tarsal joints, white. Extremely

like M. denteclypeus and differing only in having the head but little

buccate and posteriorly narrower than the eyes; the clypeus simple,

transverse and apically truncate; the thorax and scutellum very

closely punctate and not at all shining, laterally finely margined

to apex ; terebra not longer than half abdomen ; and the lower basal

nervure is distinctly antefurcal. Length, 10-11 mm. @ only.

Taken at M’fongosi in Zululand by W. EH. Jones during March and

May 1917.

Mesostenus testacellus, sp. nov.

A shining, small and clear testaceous species, with only the man-

dibular apices and most of flagellum black; the latter slender and

attenuate at both extremities, with a broad and somewhat flattened

white band immediately before apex ; frontal orbits also broadly and

definitely white. Head broad with eyes very prominent and occupy-

ing its whole sides; frons obsoletely transaciculate ; clypeus triangu-

larly prominent, basally discreted and apically subtruncate. Thorax

narrow with notauli extremely deep, crenulate and entire; sternauli

fine, semilunar and half mesopleural length; metanotum discally

deplanate and shagreened, with no basal transcarina; apical trans-

carina fine, entire and nearly straight; petiolar area short and sub-

vertical, apophyses wanting, spiracles extremely small. Scutellum

deplanate, obsoletely sculptured, sub-elongate and laterally margined

throughout. Abdomen narrowly fusiform and obsoletely shagreened ;

basal segment gradually explanate throughout and evenly aciculate ;

terebra straight, testaceous and two-thirds abdominal length. Legs

elongate and very slender, with the stout onychii alone nigrescent.

Wings narrow and flavescent-hyaline, with radix and tegulae

testaceous, and stigma paler; nervure infuscate with the basal con-

tinuous, discoidal and second recurrent quite straight ; areolet nearly

rectangular, half as broad again as high, apically pellucid, emitting

the unifenestrate second recurrent from its basal third; nervellus

strongly postfurcal and centrally intercepted. Length, 6-7 mm. Q.

Found by W. EH. Jones during April and May 1917 at M’fongosi in

Zululand. With it he took a male, which may be tentatively regarded

as belonging to this species, though differing somewhat considerably

in its black head with whole face and mouth, outer orbits and entire

scape stramineous; flagellum, stigma, and posterior tarsi black ;

shagreened postpetiole and apically obsolete areolet.

punctate-reticulate, discally transstriate beyond the single weak

basal carina, with no apophyses and small, elongate spiracles ; basal

segment glabrous and linear. Wings hyaline and somewhat narrow ;

areolet transverse and very narrow, double as broad as high, emitting

3. A rufescent-testaceous insect, with black and flavous markings.

Head black, with clypeus, mandibles except their apices, palpi and

the facial, frontal and external orbits broadly flavidous-white ; face

and clypeus densely white-pubescent, closely and strongly punctate,

with apex of latter fulvous and depressed ; frons and vertex closely

and not very strongly punctate. Antennae attenuate and very

shortly pubescent, becoming sub-piceous apically beneath, with the

third joint slightly longer than the fourth. Thorax strongly and

closely punctate ; all the pleurae black; metanotum more closely

and equally strongly, though more rugosely, punctate; apophyses

wanting. Scutellum sometimes apically flavidous. Abdomen centrally

finely punctate ; the fourth to base of seventh segments black, anus

white and petiole basally flavidous ; postpetiole strongly and closely

punctate. Legs rufescent with the anterior internally paler ; posterior

coxae beneath, apical half of hind tibiae, apices or whole of hind tarsal

joints and their metatarsal base narrowly, black ; remainder of hind

metatarsi, and the calcaria, white. Wings somewhat short, hyaline

and apically sub-infumate, with stigma and nervures black. 9. The

different coloration of the female lends it a very distinct appearance,

though the structure excepting that of the metanotum is analogous.

Head black with only the labrum, palpi, and centre of mandibles

rufescent ; antennae filiform and centrally white above; thorax

black with only mesonotum, scutellum, and frenum testaceous-red ;

metathorax rugosely punctate with apophyses small but distinct,

and petiolar area consequently defined ; abdomen black with anus

white, and whole of second segment with apex of the first red ; terebra

black and fully half length of abdomen ; all the coxae, except extreme

apices of posterior, black. Length, g@, 11-12 mm. Both sexes vary

considerably in their thoracic coloration, and the ¢ occasionally has

nothing but the antennae and sub-apical segments black. I have

seen a g with the hind coxae immaculate testaceous, and metapleurae

broadly black; in another all the coxae are entirely black with meta-

notum concolorous, and both its petiolar area and base of abdominal

petiole flavous.

I have examined the types of both sexes of this common Indian

species, which I have seen from Kashmir, Deesa, Abu, Madras, Poona,

Bombay, Bengal, Assam, and as far south as Sumatra. But it is

entirely new to Africa, where H. K. Munro captured a normal female

at Silverton, near Pretoria, on 9th December 1915.

$2. The type of this species, which I have examined, has distinct

alar areolet, the nervellus intercepted as in Sjostedtvella and all other

features of this genus. It is at once known from the above species

by its red and very sparsely punctate, shining mesonotum, with

deeply impressed notauli. The hitherto unknown female was captured

in §8.W. Africa (Mandated Territory) during 1916 by Dr. Knobel,

and differs from the male in nothing but its flavous head below

antennae, frontal orbits, propleurae above, scutellum and front coxae ;

the terebra is slender, black, and somewhat longer than the abdomen.

Sjostedtiella wurufa, sp. nov.

3. A somewhat dull and totally red species, with only the antennae

and hind legs, from immediately beyond their tibial base, black ; the

wings are infumate but not nigrescent, with nervures black and

tegulae red and extreme base of stigma flavidous. Im sculpture it

agrees ut ovum ovo with S. mgritornata, from which the dark wings,

with distinctly postfurcal lower basal nervure, will distinguish it.

Q. A shining black species with dull red thorax, instantly known

by the pure white-banded abdomen, antennae and hind tibiae. Head

shining and vertically narrow with prominent eyes; the apically

rounded clypeus and the centre of face convex and hardly discreted,

latter sparsely punctate and laterally pale flavous, mouth and apical

half of clypeus concolorous. Antennae filiform and slender, with

and apically acute. Legs slender, elongate and black ; anterior coxae

flavous beneath; anterior tibiae and, except basally, front femora

testaceous ; a third of hind tibiae immediately beyond their base,

and basal two-thirds of third hind tarsal joint, pure white. Wings

narrow with tegulae red, stigma and nervures black, and extreme

apices sub-infumate; basal nervure nearly continuous; areolet

triangular, petiolate and not broad, emitting straight recurrent nervure

slightly beyond its centre ; nervellus centrally intercepted, its spurious

nervure apically arcuate. Length, 94 mm.; terebra,3 mm. Q only.

Another male of this Cape species, taken at Salisbury in South

Rhodesia during May 1917 by R. W. Tucker, differs from the original

description slightly in coloration. The metanotum is nigrescent only

around the spiracles ; the incisures only of the four basal segments are

stramineous-white, and not “ for the greater part dull rufous”; and

the legs, “‘ coloured like the thorax,” are testaceous with the tarsi no

darker, the anterior and apices of hind coxae white, and the remainder

of hind coxae with their femora nigrescent. The species is correctly

ascribed to the present genus.

hyaline cloud ” is wanting ; the wings are uniformly nigrescent, with

the stigmal base alone conspicuously albescent. The 3 segments two

This is an extremely puzzling genus of unstable coloration, whereof

a good many species occur in Africa, though only four have hitherto

been recorded. I have before me single examples of three others:

(a) is from Zululand in January 1917, and differs from the Palaearctic

(and British) P. atrator, Rossi, in nothing but colour; the head below

the antennae is piceous with mouth and orbits testaceous, all the legs

with the exception of the front and hind coxae and the onychii are

red, and the wings infumate with violaceous iridescence and the apical

margin darker; (6) from the same locality in February, differs from

(a) solely in having the head and mesonotum brick-red and the legs,

except anterior femora and tibiae with front tarsi, black; (c) was

captured at HEshowe in Zululand during December 1916, and has

the notauli somewhat less deeply impressed with the black meta-

thorax striate ; all the remainder of thorax, the head, whole legs and

Essential Characters—Head discally broad and subquadrate ;

face centrally neither concave nor protuberant ; mandibles simple,

the teeth of unequal length and the upper not apically bifid; frons

not concave. Scutellum simple and not quadrate. Abdomen depla-

nate and not tuberculate, basally subpetiolate; spiracles of basal

segment not beyond its centre; terebra not extending beyond anus.

Legs with hind calcaria entire; tarsal claws not pectinate. Alar

areolet entire and not pentagonal.

Perilissus semrfulvator, sp. nov.

A small and somewhat stout black species, closely punctulate and

a little shining, with no flavous markings and the abdomen alone

totally fulvous. Head almost broader than thorax, subcubical,

tumidous behind the eyes; immaculate. Antennae slender, filiform

and longer than body; immaculate. Thorax closely punctulate,

with apical notauli; mesopleurae very finely punctate ; metathorax

dull with areola elongate and subparallel-sided, costulae very strong,

and petiolar area basally distinct. Scutellum black and subconvex.

Abdomen pale red throughout; basal segment not dull, alutaceous

and very finely punctate, hardly sulcate above the central and sub-

prominent spiracles; second transverse ; terebra hardly darker and

extending beyond anus. Legs slender and totally black; tarsal

claws not pectinate. Wings with radix and tegulae stramineous,

stigma piceous and slightly paler basally ; areolet large, irregularly

orbiculate and distinctly a little petiolate ; nervellus antefurcal and

intercepted at its centre. Length, 64mm. Female only.

The structure and size of this species are extremely similar to those

of P. orbitalis, Grav.; and both belong to the division known as

Ecclinops, which is characterised by having the clypeus finely punctate,

nervellus not intercepted above its centre, discoidal cell apically sub-

rectangular, head hardly broader than thorax, posteriorly sub-

parallel-sided, and the abdomen broadly red. Structurally these two

species differ in little more than the strong metanotal costulae, evenly

punctate mesopleurae and central interception of the nervellus of the

new kind. Seven species of Mesoleptina have been recorded from the

extreme north of Africa; it is interesting to find that they extend

further south. This was found at Kabete, British East Africa, on

27th April 1918.

infuscate and its apex margined ; mandibles small and stout, apically

bidentate and basally setulose; ? palpi obsolete. Antennae black,

setaceous, pilose, and but little longer than half body, with scape

cylindrical and apically truncate. Thorax stout and short, with

neither notauli nor sternauli; propleurae forming a lateral margin

to mesonotum broader than tegulae; metathorax short and sub-

vertical, with strong and semi-circular basal area from the apex

whereof a carina extends to small apophyses on either side; pleural

carinae strong; spiracles small and oblong. Scutellum small,

deplanate and not margined, with its disc centrally impressed and

basal sulcus multicarinate ; postscutellum obsolete, laterally deter-

cylindrical and short, with claws mutic and only apically curved.

Wings very broad, with tegulae testaceous, nervures and stigma

black; costa conspicuously black; basal nervure strongly curved

above, continuous through median; inner cubital but little curved ;

apical abscissa of radius double length of basal; areolet strong,

Gas 1829) pole:

I am quite unable to distinguish between a female Angitia of the

subgenus Dvuoctes, Forst., taken at Steynsburg, in Cape Colony,

during April 1914, by R. M. Lightfoot, and the normal European

form of A. apostata, Gravenhorst, which has not before been noticed

anywhere in Africa. It possesses red abdomen and terebral valvulae,

coxae, antennae, and tarsi; but this coloration appears to represent

nothing but a local form ; and in structure the two agree ad amussim.

It is quite distinct from any of the exotic species described by me in

Fauna Indica, 1913, p. 470.

Gen. RHIMPHOCTONA, Forst.

Verh. pr. Rheinl., 1868, p. 153.

Essential Characters.—Head broadly transverse and but little con-

stricted posteriorly ; clypeus short, not discreted from face and often

centrally dentate apically. Antennae setaceous and fully three-

fourths the length of body. Thorax stout, with speculum somewhat

dull; metathorax declivous throughout and a little produced apically,

with distinct areae; costulae subentire, spiracles not circular.

Scutellum neither deplanate nor margined. Abdomen strongly com-

pressed from base of third segment; terebra elongately exserted.

Areolet entire and usually petiolate ; nervellus geniculate.

clypeus not discreted, evenly punctate and dull with apex of latter

subtruncate, its centre tuberculiformly produced ; cheeks very short,

palpi testaceous; mandibles stout, shining, subparallel-sided and,

except their equally bidentate apex, flavidous. Antennae apically

setaceous ; of 2 but little longer than half body with scape apically

ferrugineous beneath, of ¢ three-fourths length of body with scape

thoracic production above hind coxae, and not curved ; areola shorter

than the transstriate and hardly impressed petiolar area, elongate-

hexagonal, and nearly twice as long as broad, emitting indistinct

costulae from its basal third; lateral carinae strong, spiracles linear.

Scutellum and its basal fovea dull, closely punctate ; the latter slightly

convex. Abdomen slender, claret-red, closely shagreened and dull,

elongately petiolate and triangular with its lower side curved and

emitting the straight recurrent nervure hardly beyond its centre ;

nervellus subgeniculate at its lower third, emitting no spurious

nervure. 9-llmm. 69.

Probably not an uncommon species. H. W. Bell-Marley found the

type at Eshowe in Zululand during December 1916; W. HE. Jones

Several species of this tribe have now been described from South

and Central Africa, but in so inadequate a manner and so scattered

a form that it appears well to give a conspectus of them here. I do

not know Ophionomorpha (Ophiomorpha, sic), Szepl., Genera Ins.,

of Cameron’s genera Ophiononeura (Ophioneura, sic), Records Albany

Mus., 1, 1904, p. 174, and Erythrophion, Ann. 8. Afr. Mus., v, 1906,

p. 87, and I consider neither them nor Stzctophion, Cam., loc. cit., p. 85,

to be distinct from Nototrachys, Marsh., whereof the following table

comprises the described species, not all of which seem good to me.

that described by him in the Records Albany Mus., 1904, flavomaculatus

is retained ; forthe second, that described in Trans. 8. Afr. Phil. Soc.,

January 1905, I have substituted tisisthenes ; and for the last, that

described in Albany Museum, April 1905, callicrates is substituted.

It is by no means clear whether their author intended the last two

as distinct inter se; as his description is considerably involved, I here

present it in a straightforward form :

Nototrachys tusisthenes, nom. nov.

Nototrachys flavomaculatus, Cam., Trans. 8. Afr. Phil. Soc.,

OY, ICDs. (Os JEG) 8).

Red, with profuse flavous markings and the abdomen discally

nigrescent. Head glabrous and nitidulous ; face, clypeus, mandibles,

palpi and orbits, pale flavous; frons closely transaciculate and

centrally carimate. Antennae nigrescent, with scape red. Thorax

with the prothorax, two basally dilated mesonotal lines, mesopleurae

except centrally above, metapleurae below radices and broadly at

apex, and declivity of metathorax, pale flavous; base of propleurae

stoutly and obliquely striate; mesonotum strongly and irregularly

transstriate, with its apex laterally punctate ; mesopleurae punctate-

reticulate below, above with basal half longitudinally striate and the

apical smooth ; metathorax closely and strongly reticulate, basally

subglabrous before the basal transcarina, which is centrally emarginate

towards scutellum ; metapleurae coarsely reticulate. Scutellum and

postscutellum pale flavous, the former reticulate. Abdomen with

second and following segments discally nigrescent ; terebra 3 mm.

in length. Legs rufescent, with the anterior tibiae paler; “ there is

a curved keel in front of the middle coxae and another between it and

the posterior.” Wings hyaline and short, about half length of body ;

stigma and nervures black. Length, 10mm. Female only.

This description was published in January 1905 ; and in April 1905

appeared another description, with the same type-locality, Dunbrody

in Cape Colony.

Nototrachys callicrates, nom. nov.

Nototrachys flavomaculatus, Cam., Records Albany Mus.,

This differs from N. tesisthenes above in the following details :

Mandibular teeth and propleural apices rufescent; pale mesonotal

lines dilated at the apex, instead of at base; base of petiolar area of

South African Ichneumonidae in the Collection of the S.A. Museum. 477

metathorax bears a flavous line; mesonotum laterally punctate

throughout ; apex of scutellum bears two short and stout carinae ;

metanotum sparsely punctate before the basal transcarina ; meso-

pleurae mainly rugose. And abdominal details are added. Post-

petiole laterally and apically carinate; apical half of basal segment

glabrous, nitidulous and dilated, with some stout apical striae.

These distinctions, though individually slight, prove in the aggregate

that tisisthenes and callicrates were not intended by Cameron to be

identical species.

Two more females were captured by R. W. H. Tucker during May

1917 at Salisbury in South Rhodesia.

Nototrachys nigricans, Cam.

This species (and presumably N. rufipes, which I do not know)

certainly does differ to an appreciable extent from Marshall’s genus

in its lack of basal metanotal carinae, in the evenly reticulate frons,

whereof the central carina is obsolete, in its very much longer cheeks

and ¢ flagellum, which is shorter, less filiform, and basally sub-

attenuate. L. Péringuey took a male during October 1918 at Caledon

in Cape Province. No female Stictophion is yet known.

Nototrachys nwvana, sp. nov.

3. A dull red species with the orbits and in g head below antennae.

pronotum, mesonotal vittae, scutellum, and in 3 sternum with anterior

coxae and most of pleurae, clear flavous ; basal scutellar sulcus, 2 disc

of second and third segments and the elongate terebra and 3 ocellar

and metathoracic spiracular regions, black. Length, 10-14 mm.

This species differs from the type of Hrythrophion ferrugineus solely

in its glabrous temples and internal orbits, basally carinate meta-

notum, infuscate costa and stigma, flavidous scutellum and orbits

and lateral mesonotal marks. It was captured by W. E. Jones

during March 1917 at M’fongosi in Zululand.

laceous throughout ; nervellus strong.

Euryophion nebulcfer, sp. nov.

A fulvo-testaceous species with only the mandibular apices, dots

behind tegulae, and abdominal apex from centre of third segment

indefinitely black. Head finely and coalescently punctate, transverse

and declived immediately behind ocelli, as broad as the prominent

eyes ; clypeus not basally discreted, apically truncate, margined and

subreflexed, basal foveae broad and deeply impressed, apical half more

coarsely sculptured ; cheeks obsolete. Antennae stout and exactly

filiform, not apically attenuate, pilose, and not longer than the body.

Thorax stout, with the evenly punctate mesonotum nitidulous ;

metathorax short, dull and obsoletely reticulate, with no discal

carinae ; spiracles large and elongate. Scutellum strongly convex,

evenly punctate, longer than broad, subparallel-sided and not

laterally margined. Abdomen stout but not broad; basal segment

smooth with its apical third subexplanate, pilose and finely punctate ;

anus subpubescent, terebra short and red. Legs neither slender nor

elongate; all the coxae closely and finely punctate throughout.

Wings ample and distinctly a little infumate, with a subcircular mark

near centre of upper basal nervure, the whole radial cell except its

base and an oblique streak in the radial cell of lower wings, strongly

infumate ; a small area immediately below stigma, base of radial cell

in all wings and a streak throughout the lower basal and the brachial

cells of upper wings, subhyaline; lower basal nervure antefurcal ;

radius evenly deflexed and subincrassate basally; nervellus strong

and intercepted a little below its centre; stigma and basal nervures

fulvous, apical ones black. Length, 17mm. Female only.

Very distinct from the known species of this genus (Morley, Revis.

Ichn., i, 1912, p. 5) in its lack of lateral frontal carinae, blotched wings,

emission of nervellus and colour of thorax. The type was captured

at Kaapmuiden in the Transvaal on 30th October, 1918, by R. W. H.

discoidal cell produced below the stigma at almost an acute angle,

from the apex whereof is emitted an elongate and very strong nervure

four-fifths of the distance to the upper basal nervure. The remainder

of the structure is normal, excepting perhaps the unusual crassity

of all the nervures, and density of ungual pectination. Scutellum

9. The Genus Eumenes, Latreile, in South Africa, with a Revision

of the Ethiopian Species (Hymenoptera).—By Dr. J. BEQUAERT,

Department of Tropical Medicine, Harvard Medical School.

(With 14 Text-figures.)

THE present paper is the second of the contemplated series on South

African Diploptera. The genus Humenes is so much better represented

in South Africa than in the equatorial regions of the continent, that

I have been induced to offer a revision of all Ethiopian species. I

was thus enabled to correct several errors of my former work (Bull.

Amer. Mus. Nat. Hist., xxxix, 1918, pp. 54-86), which should, how- |

ever, be used in connection with the present paper, for the equatorial

species.

I wish to acknowledge my indebtedness to the late Dr. L. Péringuey,

former Director of the South African Museum, for the loan of much

material. I am under especial obligation to Dr. H. Brauns, of Willow-

more, who very kindly entrusted me with the valuable types of some

species described by A. v. Schulthess. A few specimens were received

for study from Dr. G. Arnold, Curator to the Rhodesia Museum, and

some of the Katanga material was collected by my brother, Dr.

Michael Bequaert. During a brief visit at the British Museum, I had

occasion to examine a number of interesting specimens mentioned in

the paper, and I have also included records from the collections of

various other institutions. Finally, I desire to thank Dr. E. L. Gill

for the editing in the Annals of the South African Museum.

For a general account of the characters and life-history of the genus,

I refer to my Revision of Congo Vespidae quoted above. So far as

I can see, the habits of none of the peculiarly South African species

have been studied thus far, so that a wide field of discovery here

awaits some enterprising South African entomologist.

Many of the South African species appear to be quite local or very

rare, and additional forms will certainly still come to light, while

others are thus far known in one sex only. The entomologist who

wishes to understand specific limits in Humenes should learn to dis-

regard the colour pattern, which not only is often extremely variable,

484 Annals of the South African Museum.

but, in addition, is frequently almost identical in species that are

morphologically quite distinct. In closely allied forms, the shape of

the first abdominal segment and especially of the terminal hook of

the male antenna appear to afford the most reliable characters.

Since the differences are rather difficult to describe, the outline draw-

ings may prove of some help. Descriptions of supposedly new species,

based on colour markings alone, are practically worthless, as it is

impossible to recognise them without having access to the types.

The generic distinction between Humenes and Pachymenes, although

purely arbitrary, fortunately entails no great difficulty so far as the

Ethiopian fauna is concerned. In Pachymenes, the first tergite of

the abdomen is short and funnel-shaped, as a rule shorter than the

second ; in Humenes it forms a slender petiole, which is at least as

long as the second tergite. The Ethiopian Pachymenes are all of

small size, at most 10 mm. in total length. In size and general ap-

pearance Parewmenes approaches Humenes rather closely, but the

first tergite is moderately long and triangular in outline, seen from

above; in profile it is abruptly sloping just before the base, where

it presents a blunt ridge or crest, often followed by a slight constriction.

Of the two African species (one of which is as yet undescribed), one

shows a sharp and long spine on each side of the propodeum, above

the valvulae, which, however, is totally absent in the other. These

propodeal spines are not found in any Eumenes, and have sometimes

been regarded as a generic character of Parewmenes, but they are

absent in several of the Indian species of Parewmenes too. Formerly,

when the genus was known to me from descriptions only, I had placed

Pareumenes among the Zethinae. I have since had occasion to

examine several species, and find that in all of them the mandibles

are distinctly decussate and knife-shaped, as in the Humeninae. In

some they are hardly different from those of Humenes, while in others

they are much broadened and probably adapted to nesting in wood.

The two types of mandibles are represented by the two African species.

I have followed J. Sichel+ in regarding Humenes as of masculine

gender. The use of Omicron and Delta as subgeneric names will

probably be questioned by entomologists who study linguistics rather

than insects. Since, however, similar Greek letters have been com-

monly accepted as specific names, while some of them are used as

generic names in other groups, I fail to see why they should be rejected

in the Vespidae.

Subdwisions of Humenes.

After eliminating Pachymenes and Parewmenes, Eumenes still con-

tains over 200 described species, many of which differ greatly in shape.

If the fauna of a limited area be considered, they are rather easily

arranged in natural groups, but whether these are of sufficient value

to be regarded as valid subgenera is a troublesome question. Since,

however, some have been named, I shall provisionally give them sub-

generic rank. As I wish to introduce new names for three of the

groups, a brief review of the nomenclature is appended.

the genotype, and consequently Humenzdion is an exact synonym of

Eumenes proper. I can, therefore, not follow v. Schulthess where

he uses “‘ Humenes s. str.” for the group of L. mazillosus (Zool. Jahrb.

Abt. Syst., xxxvii, 1914, p. 262).

Medium-sized species, with strongly convex, subglobular thorax ;

no epicnemial anterior carina and no longitudinal keel on the posterior

part of the mesopleura. Head moderately flattened; mandibles

decussate, long and straight, slightly notched along the inner margin.

First abdominal segment variously shaped, often more or less cam-

panulate; with a basal, narrow, stalk-like portion, followed by a

much broader apical part. Apex of second tergite duplicate: the

hind margin proper forming a thin, depressed, and smooth lamella,

which is preceded by a much thickened portion ; the two are separated

by a deep groove, which is generally foveolate.

- 1 Westwood (Introd. Modern Class. Insects, II, Synopsis, 1840, p. 83) gives as

type Vespa atricornis, Fabricus, which is generally regarded as a probable synonym

of Vespa coarctata, Linnaeus. Moreover, his designation had been anticipated by

Latreille (1810).

486 Annals of the South African Museum.

This is the common type in the Palaearctic and Nearctic regions,

where it is represented by several closely allied species. In the

Oriental region it contains F. punctatus, de Saussure, and in the

Ethiopian region, #. braunszanus, A. v. Schulthess, #. lucasius, de

Saussure, #. acuminatus, de Saussure, H. capensis, A. v. Schulthess,

E. fiillebornianus, A. v. Schulthess, #. peringeyanus, A. v. Schulthess,

E. langi, J. Bequaert, EH. arnoldi, J. Bequaert, E. oculthirtus, J.

Bequaert, and £. pomiformis (Rossi). ‘

The following groups are in my opinion not sufficiently distinct

from Humenes proper to warrant their use in a subgeneric sense :—

Eumenes division Omicron, H. de Saussure, Et. Fam. Vesp., 11,

1856, p. 133.

Small species, with extremely globular and convex thorax. Meso-

pleura anteriorly with a distinct epicnemial carina, which continues

on the sternum in front of the middle coxae; without vertical keel

posteriorly. Head much flattened; mandibles relatively short,

decussate, slightly curved at apex and strongly toothed within. First

abdominal segment long and strongly campanulate : the basal, stalk-

like portion quite slender and suddenly widened into the apical,

bell-shaped part. Apex of second tergite duplicate, as in Humenes

proper.

Although in the shape of head, thorax, and first abdominal segment

there are transitional forms to Humenes proper, I retain this group

as a subgenus on the strength of the presence of an epicnemial carina

on the mesopleura. So far as known to me, this subgenus is ex-

clusively Neotropical.

8. Subgenus Afreumenes, J. Bequaert. Monotypic for Humenes

melanosoma, H. de Saussure, 1852.

Medium-sized, with moderately convex and subglobular thorax.

Mesopleura anteriorly with an epicnemial suture continuing on the

sternum in front of the middle coxae; and posteriorly with a sharp

laminate keel forming an epicnemial area for the middle legs. Head

flattened; mandibles long, straight, parallel, beak-like, slightly

notched along the inner margin. First abdominal segment long and

slender, gradually widened from base to apex, longitudinally grooved

‘above. Apex of second tergite simple.

This subgenus is exclusively Ethiopian.

4. Subgenus Delta, H. de Saussure. Type by present designation :

Vespa mazxillosa, de Geer, 1775.

Syn.: Humenes II® division, H. de Saussure, Ht. Fam. Vesp., i,

1852, p. 44; and III® division, op. cit., p. 60.

Eumenes division Delia, H. de Saussure, Et. Fam. Vesp., iii, 1856,

p. 130.

Medium-sized to large species, with moderately convex, ovate or

lengthened thorax; mesopleura with or without anterior epicnemial

carina, but without posterior keel. Head moderately flattened ;

mandibles long, straight, parallel, beak-like, slightly notched along

the inner margin. First abdominal segment long and slender, stalk-

like, but always wider at apex than at base. Apex of second tergite

simple or slightly thickened before the margin.

This subgenus is almost cosmopolitan in distribution, but apparently

does not occur in the Nearctic region. The following Ethiopian

species belong to it: F. mazillosu s(de Geer), EH. caffer (Linnaeus),

E. campaniformis (Fabricius), £. phthisicus, Gerstaecker, L. lepeleterit,

H. de Saussure, #. alluaudi, J. Pérez, and EL. macrocephala, H. de

Saussure.

The following two groups are connected with the subgenus Delta

by so many transitional forms that it appears impractical to accord

them subgeneric rank :—

5. Subgenus Zetheumenidion, J. Bequaert. Type: Humenes

femoratus, A. v. Schulthess, 1910.

Medium-sized, with ovate, broad, and moderately convex or flattened

thorax ; mesopleura without anterior epicnemial suture or posterior

488 Annals of the South African Museum.

carina ; anterior margin of pronotum with a lamellate crest. Head

but slightly flattened; mandibles short, decussate, strongly ribbed

on the outer face, with four sharp teeth along the inner margin.

Vertex with hairy fovea in female. First abdominal segment very

slender and ribbon-shaped. Apex of second tergite duplicate, the

terminal lamella often raised and collar-like. Hind femora of male

swollen ; middle and hind tibiae of female with spinose setae.

This peculiar group consists of two Ethiopian species. It strongly

suggests the Zethinae in general appearance, but the mandibles are

stillasin Humenes. The venation of the wing is as in the Humeninae,

the second cubital cell being lozenge-shaped and its lower or cubital

margin being but slightly deflected where it receives the first recurrent

nervure. In the Zethinae the first section of the lower margin of the

second cubital cell is usually placed vertically upon the first recurrent

nervure, which runs almost in a straight line with the remainder of

the cubitus.

On account of the rather short mandibles, [schnogasteroides, Magretti

(Bull. Soc. Ent. Italiana, xv (1883), 1884, p. 251; Ann. Mus. Civ.

Genova, xxi, 1884, p. 603), appears to be related to Zethewmenidion,

and I have little doubt that it, too, represents a group of Humeninae,

perhaps not really distinct from Humenes. The only species, [schno-

gasteroudes flavus, Magretti, of Abyssinia, has apparently not been

found again. It is, however, quite possibly identical with Humenes

leptogaster, KF. Walker (List of Hymenoptera collected by J. K. Lord

in Egypt, 1871, p. 30), of which I have seen the type (g) and two

other males, from Wady Ferran (= Wady Faran in the Peninsula of

Sinai), in the British Museum. It is about the size of EL. femoratus,

but extremely slender; not only is the first abdominal segment very

long and thin, but the second is narrowed at the base into a long neck,

as in Paramischocyttarus. Yet the shape of the mandibles leaves no

doubt as to its being a Humenes. It will undoubtedly form a distinct

subgenus, for which Magretti’s name Ischnogasteroides will perhaps

be available. For this reason I refrain from proposing a new term.

6. Subgenus Oreumenes, J. Bequaert. Monotypic for Humenes

harmandi, J. Pérez, 1905.

Medium-sized species; mesopleura without anterior epicnemial

suture or posterior carina. Mandibles of the usual Humenes type.

Vertex without hairy fovea in female. Antennae 12-segmented in

female; 13-segmented in male, the last segment short, of normal

shape, not forming a recurved hook. Hind margin of second abdominal

tergite shghtly duplicate.

The unusual shape of the male antennae, which I have observed

in several specimens of #. harmandi, from Japan and China, was noted

by Pérez in his original description.

The following species should be eliminated from the list of Ethiopian

Humenes :—

Eumenes bisignatus, F. Walker, 1871, described from ‘ Wady

Ferran,” which is in the Sinai Peninsula.

Eumenes dilectula, F. Walker, 1871, described from “‘ Wady Genneh,”’

probably in the Sinai Peninsula or in Lower Hgypt.

Eumenes dyscherus, H. de Saussure. As explained below, this is a

South American wasp.

Eumenes elegans, H. de Saussure. This was described from Arabia

and the Kast Indies; it is discussed in the sequel in connection with

E. esuriens var. gracilis, H. de Saussure.

Eumenes leptogaster, F. Walker, 1871, described from “ Wady

Ferran,” which is in the Sinai Peninsula.

Eumenes maculinoda, P. Cameron, 1910 (3). Owing to the small

size (total length, 7 mm.) and the short first abdominal segment,

this is probably a Pachymenes or Labus.

Eumenes ornatwentris, P. Cameron, 1910 (2). This may be the

female of maculinoda, and is likewise either a Pachymenes or a Labus.

Eumenes rufoloneata, P. Cameron, 1905. This is also, in my opinion,

either Pachymenes or Labus.

slender, about as long as the thorax, about seven times as long as its

greatest width seen from above; in profile but little and quite gently

curved, uniformly thick throughout, except near the base; dorsally

it is distinctly flattened and more or less ribbon-shaped, though

widened at the apex and somewhat more so in the basal third, where

the spiracles form well-marked protuberances on the sides; there is

a distinct longitudinal groove over the basal half. Second segment

with a short but distinct basal neck, regularly campanulate, the

tergite but little more convex than the sternite, distinctly longer than

high in profile and slightly longer than wide from above, not in the

least compressed ; the hind margin of sternite and tergite conspic-

uously duplicate; the apical lamella translucent, smooth, somewhat

upturned and more or less collar-like ; the preapical swelling quite

conspicuous, followed by a deep, transverse channel with a series of

short ribs; base of second sternite flattened, but not depressed.

Puncturation coarse and dense on the thorax, somewhat finer but

still more dense on the head; the clypeus very coarsely punctate ;

tegulae with a number of deep and large punctures and a small, smooth

area near the outer margin. The hind corners of the mesonotum have

a short smooth space on each side above the tegulae, connected with

the smooth post-tegulae. First tergite with minute, scattering punc-

tures, which are much larger and deeper on the anterior half in the

middle. Second segment almost impunctate, except before the

preapical swelling, where there are a series of very large and deep

punctures, more abundant in the middle than on the sides. Succeeding

segments impunctate. Pubescence very sparse, except on the head

and propodeum, where it is greyish-white.

Black, abundantly marked with ferruginous red as follows: clypeus

(somewhat orange), mandibles (with more brownish apex and teeth),

antennae (the four apical segments brownish above), a spot at the

bottom of ocular sinus, an elongate spot in the upper part of the

temples, pronotum (the extreme lower edges black), tegulae, the

upper plate of the mesopleura, scutellum, postscutellum, propodeum

(except for black margins and median line), legs, sides and apex of

first segment quite broadly, second sternite (except for a wide, longi-

tudinal, black band not reaching the apex), second tergite (except for

a broad, median, triangular black spot, which is drawn out into a

point in the middle toward the basal neck), and ill-defined apical

bands on some of the succeeding segments. Often the black is more

extensive, the pronotum, scutellum, and upper plate of the mesopleura

being blotched with that colour ; the basal neck of the second segment

may be entirely black and connected by a wide band with the black

area of the second tergite. At the apex of the first and second tergites

the ferruginous sometimes shades into orange. Hind tibiae rather

broadly yellowish along the outer surface. Wings decidedly smoky

throughout, somewhat darker anteriorly, with beautiful purplish and

golden reflections, the costa amber-coloured ; remaining nervures and

stigma blackish brown.

Length (h.--th.+t. 1+2): 14 to 14-5 mm.

Male.—Clypeus decidedly longer than wide; the apical, free part

slightly longer than the interocular portion; apical margin about

half the width of the clypeus, distinctly though shallowly emarginate,

with sharp edges. Vertex without fovea. Inner orbits but slightly

farther apart on the vertex than at the clypeus. Posterior ocelli

about as far from each other as from the inner orbits, but considerably

farther from the posterior margin of the vertex. Antennae rather

short and thick; the flagellum gradually thickened toward the apical

half; segments 6 and 7 almost square; 8 to 12 wider than long ;

terminal hook short and thick, straight, very sharply pointed from

the very base, triangular in profile, flattened and obtusely rounded

off at apex when seen from above, reaching to near the base of the

eleventh antennal segment. Legs short and conspicuously thickened,

especially the femora. Hind femora much swollen, spindle-shaped,

about three times as long as greatest width and but little flattened ;

in the basal half the under side shows an oblique, broad groove, which

does not reach the base and bears in its middle a short and heavy

translucent spine. The hind tibiae are somewhat curved and gradually

swollen in their apical half. Claws deeply bifid before the apex.

Last sternite slightly flattened, uniformly and densely punctate.

Clypeus yellow; a yellow spot on the ferruginous upper plate of the

mesopleura, just below the base of the wing; outer side of tibiae

broadly yellow. The remainder as in the female.

The species was originally described from Lobatsi, Bechuanaland,

and Grootfontein, South-West Africa. The female of Johannesburg

(in Dr. Brauns’ collection) is labelled “ type,’ and the female of

Stellenbosch (in the South African Museum) “cotype’”’; but these

specimens were not mentioned in the original description, although

they have been identified by Dr. v. Schulthess. Cameron’s #. pulchri-

pennis was described from Kranspoort, Transvaal; a specimen thus

named by Cameron, in the Stockholm Museum, was recognised as

with such identification.

Female.—Head seen in front about as broad as high. Clypeus

slightly wider than long, forming a flattened hexagon in outline,

moderately but rather suddenly convex in the centre, slightly flattened

before the anterior margin; the anterior, free portion about as long

as the basal, interocular part; the apical margin measuring about

one-third of the total width of the clypeus, shallowly and evenly,

though quite distinctly emarginate, with prominent, bluntly triangular

edges. Vertex with a small, hairy, transverse fovea a short distance

from the hind margin. Vertex and temples quite long, even longer

than in #. femoratus, margined behind with a sharp, continuous rim ;

the posterior ocelli about one and one-half times as far from the hind

margin of the vertex as from the inner orbits. Ocelli placed in a

slightly flattened triangle, the posterior ones distinctly closer to each

other than to the inner orbits, the anterior one larger. Front un-

usually wide and almost flat between the antennae, with the merest

trace of swelling and longitudinal, impressed line above. LHyes bare,

about as far apart at the clypeus as on the vertex. Mandibles shaped

as in EL. femoratus, externally ribbed and grooved, and with the row

of stiff, pale setae along the outer margin; the apex, however, is

hardly curved and quite obtuse, while the teeth along the inner

margin are oblique and blunt. Maxillary and labial palpi as in #.

femoratus. Antennae quite short and stout, the flagellum more

distinctly swollen in the apical half than in £. femoratus ; segments, 7

nearly square, 8 to 11 distinctly wider than long, 12 about as long as

wide at base. Thorax quite elongate and depressed ; conspicuously

flattened on the dorsal as well as on the ventral side; about two and

one-half times as long as high in profile ; quite wide seen from above,

being less than one and one-half times as long as wide. Pronotum

very broadly and squarely truncate anteriorly; margined with a

collar-shaped, translucent, pale lamella, which is much more pro-

nounced than in EL. femoratus ; laterally the lamella is evenly curved

backward, so that the humeral angles, though well marked, are quite

blunt ; the pronotum is but slightly narrower anteriorly than before

the base of the wings. Mesonotum quite slightly and very evenly

convex, about as long as wide, with a median, smooth line in its

anterior third. Scutellum and postscutellum flattened, but very

slightly sloping, being still part of the dorsal surface of the thorax ;

the scutellum with a rather superficial, impressed, median line in its

anterior half. Propodeum elongate, seen from above about as long

as the scutellum, distinctly composed of a dorsal face which continues

the gentle slope of the postscutellum, and a vertical, posterior aspect ;

quite gently rounded off on the transition between the two areas ;

seen from above the two halves of the propodeum are quite bulging

posteriorly, being separated by a deep and broad groove, which

continues dorsally to the postscutellum as a deep but narrow channel.

Mesopleura without carinae along the epicnemial depressions for the

fore and middle legs; these depressions quite strongly marked.

Mesosternum unusually long and conspicuously flattened. Legs

stout and short, as in #. femoratus; middle and hind tibiae with

stiff, pale setae on the outer surface and a dense comb of pale spines

at the outer apex. Middle tibiae with one spur. Claws with an inner

tooth shortly before the apex. Wings short and wide, the venation

showing the same peculiarities as in #. femoratus. First abdominal

segment quite long and slender, much longer than the thorax, but

distinctly shorter than head and thorax, about eight times as long

as its greatest width seen from above; in profile but little and quite

gently curved, uniformly thick throughout except at the extreme

base ; dorsally it is not appreciably flattened, except just before the

apex, without trace of groove; it very gradually widens to the basal

third, where the spiracles form low, lateral protuberances, so that the

segment is here about as wide as at the apex; between the apex and

the spiracles the sides are very gently and slightly curved inward.

Second segment with a short, but distinct, basal neck, regularly

campanulate, a little more convex dorsally than ventrally, much

longer than high in profile, the swollen portion slightly longer than

wide seen from above ; not in the least compressed ; the hind margin

conspicuously duplicate, as in EL. femoratus. The second sternite is

distinctly depressed and somewhat concave in the middle over its

basal third. Puncturation of the head as in EL. femoratus, very deep

and coarse on the clypeus; that of the thorax somewhat finer, the

smooth intervals between the punctures being larger, so that the

thorax is much more shiny; there is a smooth area along the apical

margin of the postscutellum, quite conspicuous in the middle. First

tergite with quite scattered and minute punctures, which are but

little larger in the middle of the basal half. The puncturation of the

second and succeeding segments as in EL. femoratus. Pubescence as

in £. femoratus.

Black, rather inconspicuously marked with ferruginous red (often

shading into brown) as follows: clypeus, mandibles, basal half of

antennae, a spot at the bottom of ocular sinus, the temples quite

extensively, pronotum (except extreme lower edges), tegulae, the upper

plate of mesopleura, scutellum (except anteriorly), postscutellum,

propodeum (except for black margins and median line), legs (hind

tibiae and middle and hind tarsi black, with ferruginous last tarsal

segment), first abdominal segment (except for a dorsal, black band,

much narrowed near the base), second segment broadly at base and

narrowly at apex, the ferruginous colour spreading somewhat over

the sides of the sternite. Apex of the first tergite with two triangular,

ivory-white spots, confluent or separated in the middle; the hind

tibiae with a narrow, ivory-white line along the outer surface; a

narrow, ivory-white line along the anterior margin of the pronotum.

Wings decidedly smoky, except in the posterior half of the hind

wings; with purplish tinge, but without the golden reflections of

E. femoratus. The two females seen, although from quite distant

localities, are astonishingly alike in coloration.

Length (h.- th.+t. 142): 16 mm.

Male.—Clypeus more elongate than in the female, about as long

as wide; the apical margin as deeply and broadly emarginate as in

the female, but the edges much sharper. Vertex without fovea.

Posterior ocelli nearly twice as far from the hind margin of the vertex

as from the inner orbits and slightly farther from each other than from

the eyes. Antennae quite short and thick, the flagellum conspicuously

swollen; segments 5 and 6 almost square, 7 to 12 much wider than

long; terminal hook shaped as in the male of H. femoratus. Legs

short and conspicuously thickened as in EF. femoratus; the hind

femora somewhat less swollen, about three and one-half times as

long as greatest width ; in the basal half, where the femora bear the

same heavy, short spine as in #. femoratus, the under side is obliquely

depressed, but not grooved; the hind tibiae are but slightly curved.

Claws deeply bifid before the apex. Clypeus ivory-white with a

ferruginous median spot; an ivory-white line on the under side of

the scape; pale spots on the under side of the antennal segments

9to 11; the anterior margin of pronotum more distinctly ivory-white

than in the female; apical ivory-white markings on the first tergite

as in female; broad apical ivory-white bands on tergites 3 to 7 and

on sternites 3 to 6, bisinuate anteriorly ; the outer surface of all the

tibiae and of the basal segment of the tarsi rather broadly ivory-white.

The remainder as in the female.

This species, though evidently allied to E£. femoratus, is readily

distinguished by the unusually depressed thorax. The flattening of

the thorax has sometimes been regarded as a characteristic of Pareu-

menes, but the present species shows that this peculiarity is not of

generic value among the Humeninae.

This Palaearctic species is found in Egypt and Libya and enters

the extreme north-eastern part of the Ethiopian region. It is here

mainly included to publish the synonymy of Labus superbus, of which

I have examined the type, from the White Nile, at the British Museum.

502 Annals of the South African Museum.

I am unable to distinguish it from #. pomeformis, and the identity

of the two had apparently been recognised by the late Meade Waldo,

since the specimen was placed with #. pomzformis in the collection.

It is generally supposed that #. pomeformis is but a variation of

the common Palaearctic H. coarctatus (Linnaeus); but, with the

limited material before me, it appears quite distinct. The punctura-

tion of the second abdominal tergite and sternite is much more pro-

nounced and denser than in coarctatus. It is, however, not the place

here to discuss these two species further.

distinctly flattened above, about two and one-half times as wide as

the basal, stalk-like portion, the passage between the two being rather

abrupt; the spiracles placed about midway the length of the segment

and hardly projecting ; dorsally there is a faint longitudinal groove

toward the apex and a transverse, preapical depression. Second

half of second sternite and of third tergite, and remainder of abdomen ;

legs, except for the coxae and the middle and hind trochanters. A

narrow, pale yellow band covers the apical, swollen margin of the first

tergite. Occasionally the clypeus, mandibles, and postscutellum, and

perhaps some other parts, may be more orange-red than ferruginous.

The posterior transverse ridges, connecting the sides of scutellum

and postscutellum with the base of the wings, are pale coloured, more

or less translucent. Wings but feebly smoky, with a slight horny-yellow

tinge, darker toward the costa, faintly violaceous in the radial cell.

EL. braunsianus is the Ethiopian representative of a type of Humenes

more frequently found in the Nearctic region (#. bollw, Cresson, and

approaches H. peringeyanus, from which it is readily separated by

the much shorter and broader first abdominal segment.

and the succeeding tergites are also more or less marked with yellow.

The remainder as in the female.

The coloration is evidently variable. The above description is

based on a pair taken by Dr. H. Brauns at Willowmore. In the type,

and two other specimens at the South African Museum, the yellow has

replaced most of the ferruginous red colour, especially on the thorax.

Structurally, however, all these specimens are alike.

The morphological peculiarities are described and figured for £.

langi, in which I now recognise a colour race of #. fillebornianus.

The typical form, of Hast Africa, is black, more or less extensively

ferruginous on pronotum, mesopleura, sides of propodeum, under side

of abdomen (especially on the first segment), legs, mandibles, and

under side of antennae. In the three specimens examined the only

pale yellow markings are a short line along the outer orbits in the

upper part of the temples, a faint indication of posterior margin

of pronotum in the centre, and a broadly interrupted apical band on

the first tergite. The clypeus of the male is black, with somewhat

ferruginous apical edges.

This is the smallest of the Ethiopian Humenes and should be readily

recognised by the coarsely sculptured, almost foveolate second tergite,

as well as by the peculiar shape of the first abdominal segment.

The species was originally described from Zanzibar and Lake Nyasa.

pp. 56, 85 (9; figs. 71-73), and 276.

This is evidently the West African form of H. fiillebornianus, from

which it differs merely in the almost total absence of ferruginous

markings. It was described on a unique female from Boma, Belgian

510 Annals of the South African Museum.

Congo, which had many, irregular, transverse wrinkles on the posterior

half of the second tergite. Three additional specimens from the Belgian

Congo do not possess these wrinkles, but instead the second tergite

is coarsely punctate as in the Hast African £. fiillebornianus. Since

I am unable to find other differences, I must regard the wrinkling in

the type specimen as abnormal and due to some injury during the

pupal stage.

A female of the var. langz in the Congo Museum, at Tervueren,

Belgium, was obtained in the Manyema by R. Mayné. It is still more

black than the type; the under side of the three last antennal seg-

ments, the mandibles and fore tibiae are slightly ferruginous; the

apex of the fore tibiae is spotted with pale yellowish on the outer side ;

the only pale yellow markings of the abdomen are a small apical spot

on each side of the first tergite ; the pronotum bears a narrow whitish

line medially, along the hind margin. This specimen reaches 11 mm.

(h.+th.—+t. 1+2).

Male of var. lang (undescribed).—Head relatively higher than in

the female. Clypeus more elongate, considerably narrowed above,

about twice as long as wide; the apical margin quite shallowly

sinuate; the free, apical portion only half as long as the interocular

part. Inner orbits twice as far apart on the vertex as at the clypeus.

Flagellum moderately and quite gradually swollen; antennal seg-

ments 9 to 12 slightly wider than long; the hook-like segment rather

small, wedge-shaped, much narrowed into a very long, narrow, and

sharp apex, which reaches the base of the eleventh antennal segment.

Legs normal. Seventh sternite uniformly convex and shiny. The

remainder as in the female; the coloration also similar. In one

specimen the clypeus is entirely black, densely covered with silvery

pile ; a small, whitish dot above the base of antennae ; a short, whitish

line along outer orbits in upper part of temples ; the posterior margin

of pronotum narrowly whitish in the middle; whitish outer edges of

the apex of first tergite ; a narrow, whitish line on each side on the

preapical swelling of second tergite; and a whitish streak on the

outer side of the fore tibiae. The other male has only the white dot

above the base of the antennae and white line of the outer orbits,

being otherwise completely black.

Length (h.+th.+t. 142): 7:5 to 8 mm.

The two male specimens on which the foregoing description is based

were collected by Maurice Bequaert, at Coquilhatville, Belgian Congo,

October 15, 1922.

slightly longer than wide, elongate hexagonal, quite evenly convex

toward the centre; the anterior, free portion but two-thirds the

length of the upper, interocular part; the apical margin nearly half

the total width of the clypeus, with a moderately deep, broadly open,

arcuate emargination and extremely obtuse, broad edges. Vertex

without fovea. Ocelli placed in a flattened triangle ; posterior ocelli

slightly farther apart than from the inner orbits; the anterior ocellus

considerably larger. Front very slightly raised but not carinate

between the antennae. Hyes densely covered all over with long,

erect, greyish-white pubescence, quite apparent under a magnifica-

tion of 10 diameters; the inner orbits much farther apart on the

tennae moderately elongate; the flagellum conspicuously swollen in

its apical half; segments—8 almost square, 9 to 11 wider than long,

12 about as long as wide at base. Thorax subglobular, about one-

sixth longer than high seen in profile, and but little longer than wide

seen from above. Pronotum not quite straightly truncate anteriorly ;

the margin completely rounded off and smooth in the middle; on the

sides (dorsally) with an extremely fine, raised line, which is not visible

with a hand lens of 10 diameters; below the humeral angles there is

a more distinct, but flattened and blunt, vertical carina, which is

deeply sinuate about the middle of its length. Humeral angles

hardly defined, very obtusely rounded off. Mesonotum somewhat

longer than wide, with a smooth but rather dull line in the middle

of its anterior half. Scutellum quite uniformly swollen, the anterior,

horizontal half gradually rounded off into the posterior, sloping

portion; with a median, smooth, slightly raised, longitudinal line.

Postscutellum hardly convex and entirely within the posterior, vertical

slope of the thorax; divided by a fine, median, longitudinal furrow.

Propodeum extremely short seen from above, but little convex,

completely rounded off, without ridges or projecting angles; the

of the usual Humenes type. First abdominal segment quite long and

slender, but little shorter than head and thorax, about five times as

long as its greatest width seen from above ; in profile distinctly but

quite gently curved, slightly and quite gradually swollen toward the

apical half; seen from above the tergite widens very gradually from the

base to Just before the middle, where the spiracles are slightly pro-

tuberant ; thence the increase is quite slow to the apex, which is the

widest part of the tergite; dorsally the segment is not appreciably

flattened, but its apical half bears a longitudinal, shallow groove,

which becomes more distinct posteriorly. Second segment quite

but not in the least compressed; but slightly longer than high in

profile ; basal neck short, but distinct ; apex or sternite and tergite

duplicate ; the terminal lamella quite thin, translucent, flat, separated

from the preapical swelling by a minutely foveolate, deep furrow ;

second sternite flat at base. Head and thorax dull, rather sparsely

covered with scattered punctures of medium size; they are somewhat

coarser on scutellum, postscutellum, and posterior part of propodeum ;

clypeus impunctate, dull. First abdominal tergite with very few,

minute punctures, almost impunctate ; second tergite fairly uniformly

covered with moderately dense punctures, similar to those of the

mesonotum ; they are quite sparse and minute on the second sternite ;

the remainder of the abdomen impunctate. Pubescence quite long

and dense on head, thorax, and abdomen, giving to the insect a dull,

greyish appearance; there is also an admixture of shorter, somewhat

silvery tomentum, especially striking on the clypeus.

Black, with scant and dull ferruginous markings as follows : clypeus

(except for a large, median, black spot in the upper half), mandibles,

scape (except for a black line on the upper side) and under side of

flagellum, pronotum (except for a large black spot on each side),

margins of tegulae, posterior two-thirds of scutellum, the sides of

propodeum quite broadly, the legs (except for the black middle and

hind tarsi), the under side of the first abdominal segment, the extreme

sides of the second tergite, and most of fourth to sixth segments.

Ivory-white markings are reduced to a narrow, transverse fascia a

short distance before the apex of the postscutellum ; narrow, almost

linear, apical fasciae on the first tergite and on the second tergite and

sternite; a preapical, median streak on the third tergite; a line

-along the outer orbits in the upper part of the temples; and a line

on the upper (outer) surface of middle and hind tibiae. Wings sub-

hyaline, smoky and purplish before the stigma and in the radial cell.

Length (h.+th.+t. 1+2): 13 to 14 mm.

Male.—Clypeus much longer than wide; the anterior, free portion

only half as long as the interocular part ; the apical margin emarginate

as in the female. Inner orbits twice as far apart on the vertex as at

the clypeus. Flagellum rather conspicuously swollen in the apical

half, where the segments are slightly beaded; antennal segments, 8

almost square and 9 to 12 wider than long; terminal hook long and

slender, slightly curved, narrowed from the very base to a long and

very sharp point, which reaches about midway the tenth antennal

segment. Legs somewhat shorter than in the female, but otherwise

normal. Last sternite normally convex, impunctate. The remainder

magnification (An. Mus. Nac. Buenos Aires, (3), vi, 1906, p. 312). In

the species here described, the pile of the eyes is quite long and

abundant.

The nearest ally appears to be #. lucaswus, which, however, is quite

distinct in the bare eyes, the much broader clypeus of the female, the

broader and relatively shorter first tergite, and the coarse and dense

puncturation of head, thorax, and first cergite.

Venation of wings of the usual Humenes type. First abdominal seg-

ment long and slender, about as long as the thorax in profile, about

four times as long as its greatest width seen from above; in profile

distinctly, but quite gently curved, slightly and quite gradually

swollen toward the apical half; seen from above the tergite widens

quite gradually from the base to near the middle, where the spiracles

post-tegulae, a spot on the upper plate of the mesopleura, the major

part of the scutellum, the sides of the propodeum quite extensively,

the sides of the first and second abdominal segments (the ferruginous

extending somewhat angularly toward the middle of the second

tergite), the larger part of the succeeding segments, and the greater

part of the legs (middle and hind tarsi blackish-brown). The ivory-

white markings are a short line along the outer orbits in the upper

part of the temples, a narrow fascia along the entire posterior margin

of the pronotum, a transverse fascia over the postscutellum, a narrow

apical fascia on the first tergite and on the second sternite, and a much

E. lucasius was originally described from Abyssinia. The synonymy

of E. schultzeanus was recognised by A. v. Schulthess himself (Societas

Entomol., xxv, 1910, p. 24); that of Rethus broom: by Cameron (Ann.

Transvaal Mus., 1, 3, 1910, p. 156) and by Meade Waldo (Ann. Mag.

Nat. Hist., (8), xiv, 1914, p. 404). Cameron has also synonymysed

with it Zethus favillaceus, Walker (List of Hymenoptera collected by

J. K. Lord in Egypt, 1871, p. 28), of Tajura, on the African shore of the

Gulf of Aden. Whether he was correct is impossible to decide from

the description alone, and it is not likely that Cameron saw Walker’s

type.

postscutellum. Mesopleura without carinae or ridges along the

epicnemial depressions for the fore and middle legs. Legs normal,

slender. Venation of wings of the usual Humenes type; the third

cubital ceil is relatively shorter and higher than in #. acuminatus,

being much shorter on the cubital vein than the second. First

abdominal segment quite long and slender, much more slender than in

EH. acummmatus and even more so than in #. lucasvus, about as long as

head and thorax together in profile; slightly over five times as long

as its greatest width seen from above; in profile distinctly but gently

curved and quite gradually swollen toward the apical third; seen

from above the tergite widens quite gradually from base to apex,

which is the widest part; about midway the spiracles are rather

conspicuously protuberant ; dorsally it is but slightly flattened and

very superficially grooved, except toward the apex, where it is deeply

furrowed. Second segment bell-shaped and rather strongly swollen,

much more convex dorsally than ventrally, very slightly compressed ;

about as high as long in profile, distinctly longer than wide seen from

above; basal neck well developed, relatively longer and narrower

than in #. acuminatus ; apex of sternite and tergite distinctly dup-

licate ; the terminal lamella thin, translucent, flat, separated from

the preapical swelling by a minutely foveolate, deep furrow; second

sternite flat at base. Puncturation moderately coarse and dense on

head and thorax; on the dorsum the punctures are somewhat finer

than in #. acuminatus, the difference being especially marked on the

pronotum ; the propodeum and mesopleura, however, are not in the

least subreticulate as in that species ; on the mesopleura the punctures

are small and remote; the base of the postscutellum is covered with

a series of fine rugosities, placed more or less longitudinally ; tegulae

with very few, irregular punctures ; clypeus dull, almost impunctate,

with very few, scattered, and superficial punctures. First abdominal

tergite medially with sparse and rather minute punctures. Second

tergite with quite minute punctures, scattered fairly uniformly over

the whole surface ; those of the sternite larger, but very sparse. The

remainder of the abdomen impunctate. Pubescence short and sparse,

except on the head.

which is wider in the basal half and broadens again before the apex),

second segment (except for a wide, black, dorsal mark in the basal

half, forming an inverted T), the remainder of the abdomen, and the

legs (middle and hind tarsi brownish). The few ivory-white markings

are much as in #. lucasvus and H. acuminatus : a small spot between

the base of the antennae, a short line along the outer orbits in the

upper part of the temples, a narrow fascia along the posterior margin

of the pronotum, a transverse fascia over the postscutellum, a narrow

apical fascia on the first tergite and second sternite, a much broader one

on the second tergite, apices of fore coxae and of foreand middle femora,

and the outer surface of all tibiae. Wings subhyaline, but slightly

smoky anteriorly and in the radial cell, which is faintly purplish.

This species is closely allied to both £. lucasius and HE. acuminatus,

and from published descriptions it would be quite impossible to

differentiate it. From both species it differs conspicuously in the

shape of the first abdominal segment, which is quite slender and evenly

widened from base to apex. The thorax is more slender and narrower,

seen from above, than in E£. acuminatus, from which it differs also in

the finer sculpture of the mesopleura and the less thickened antennae ;

the slight difference in the venation is perhaps not reliable. From

E. lucasius it differs also in the pronotum being more distinctly

rimmed along the anterior margin, and in the puncturation, which is

sparser and much finer on the first and second tergites. In general

aspect £. arnold: is not unlike H. oculchwrtus, but it has bare eyes and

lacks the conspicuous pubescence of the body.

EH. arnoldi. Pronotum nearly squarely truncate; the anterior margin

rimmed throughout with a very fine, raised line; below the humeral

angles it becomes a strong but flattened carina, deeply sinuate about

midway. Humeral angles quite distinct, but bluntly rounded off, the

dorsal aspect of the pronotum being relatively wide. Mesonotum but

slightly longer than wide, with a faint trace of median, impressed line

in the anterior half. Scutellum moderately and uniformly convex,

very gently sloping posteriorly ; divided by a fine, longitudinal,

median line, which is slightly raised in the anterior half. Postscutellum

almost flat, entirely within the posterior slope of the thorax, without

any trace of median line. Propodeum quite short seen from above,

moderately convex, completely rounded off, without ridges or pro-

jecting angles; the median groove broad and shallow, a little deeper

above the base of the abdomen, almost reduced to a fine, impressed

line in the upper half. Mesopleura without carinae or ridges along

the epicnemial depressions for the fore and middle legs. Legs normal,

slender. Venation of wings of the usual Humenes type; third cubital

cell relatively long, being not or but little shorter on the cubital vein

than the second; first abscissa of radial vein (on first cubital cell)

about twice as long as the second (on second cubita! cell) ; the third

abscissa convex into the radial cell and about as long as the two

preceding abscissae together; the third cubital cell but little higher

than long on the radial vein. First abdominal segment long, but

moderately slender, much less so than in £. arnoldi and even less than

tinctly but gently curved and much more swollen than in #. lucasius

and 4. arnoldi, being thicker in the middle than at the apex ; seen from

above the basal third forms a narrow stalk, which widens rather

rapidly to midway, where the spiracles are hardly protuberant; the

apical half is fairly parallel-sided, nearly three times as wide as the

tudinal groove; there is a distinct, transverse depression before the

slightly thickened apex. Second segment bell-shaped and rather

strongly swollen, much more convex dorsally than ventrally, not

appreciably compressed, slightly longer than high in profile and longer

than wide seen from above; basal neck quite short and but little

narrower than the apex of the first tergite; apex of sternite and

tergite distinctly duplicate; the terminal lamella thin, translucent,

flat, separated from the preapical swelling by a minutely foveolate,

deep furrow ; second sternite flat at base. Puncturation quite coarse

and dense on head and thorax; the propodeum and especially the

mesopleura, subreticulate ; tegulae almost impunctate; clypeus dull,

its basal half with scattered, rather large punctures, which are

especially conspicuous in the middle. First abdominal tergite fairly

uniformly covered with scattering, minute punctures, with a few

larger ones near the middle line. Second tergite with very minute

punctures, scattered all over and becoming rather indistinct toward

the preapical swelling; those of the sternite very sparse and quite

small. The remainder of the abdomen impunctate. Greyish-white

pubescence long, erect, and dense on head and thorax; very short

and sparse on abdomen; the clypeus somewhat silvery; the whole

body dull, due to a brownish tomentum, especially distinct on the

second tergite.

Black, abundantly marked with ferruginous as follows: clypeus

(except for a median black spot near the base), mandibles (black at

extreme base), antennae (brownish-black on the upper side), pronotum

(except for a black spot in the posterior haif), tegulae, post-tegulae,

a large spot on the upper plate of the mesopleura, scutellum (except

for the margins and a black median line), major part of propodeum

(except the broad anterior and lateral margins and middle line), first

abdominal segment ventrally and on the sides of its apical half, sides

of second tergite forming broad triangular spots a short distance from

the base, blotches in the apical half of the second sternite, remainder

of abdomen, and legs (except for the brownish-black basal two-thirds

of hind femora; the coxae somewhat brownish). The ivory-white

markings are almost exactly as in #. arnoldi: a small, transverse spot

between the base of the antennae, a short line along the outer orbits in

the upper part of the temples, a line along the posterior margin of

the pronotum (rather indistinct toward the base of the wings), a trans-

verse fascia over the postscutellum, a narrow apical fascia on the

first tergite and second sternite, a much broader one on the second

tergite (somewhat emarginate in the middle), the extreme apex of

the fore coxae, a spot near the apex of the middle tibiae, and a line

on the outer surface of all the tibiae. Wings subhyaline, slightly

smoky and somewhat purplish along the anterior margin and in the

subcostal and radial cells.

Length (h.+th.+t. 1+2): 12 mm.

Male.—Clypeus about one and one-half times as long as wide; the

anterior, free portion about two-thirds the length of the basal, inter-

ocular part; the apical margin somewhat less emarginate than in

the female. Inner orbits twice as far apart on the vertex as at the

clypeus. Flagellum very gradually swollen toward the apical half ;

antennal segments—5 and 6 slightly longer than wide, 7 nearly square,

8 to 12 wider than long ; terminal hook as in 4. lucasvus, very slender,

almost straight, narrowed from the very base to a long and very

sharp point, which reaches to near the base of the tenth antennal

segment. Last sternite normally convex, impunctate, except on the

sides before the apex. Clypeus impunctate. The remainder as in

the female. Coloration similar, but the clypeus entirely ivory-white ;

apical, ivory-white fasciae also on tergites 3 and 4 and on sternites

3 to 6; all tibiae with a broader, ivory-white line on the outer surface.

In the one specimen seen the ivory-white line is lacking along the

posterior margin of the pronotum ; also the third cubital cell is much

longer than the second, but this is evidently due to an abnormal

shortening of the second cell, as the second recurrent vein ends just

beyond the second transverse cubital in the extreme corner of the

third cubital cell (in the female described above the second recurrent

ends normally in the second cubital cell considerably before the second

transverse cubital).

Length (h.+th.+t. 1+2): 10-5 mm.

The two specimens on which the above description is based were

identified as HL. acuminatus by Dr. A. v. Schulthess. The male agrees

with de Saussure’s very brief description and figure; the author

mentions expressly that the thorax is quite broad at the pronotum,

which is one of the main differences of this species with H. arnoldi and

E. lucasius. No complete description of the species has ever been

given.

Gribodo (Ann. Mus. Civ. Genova, xxi, 1864, p. 296) described from

Abyssinia (Let Marefia, Scioa) the supposed female of acuminatus.

His description, however, could apply equally well to that species,

to E. arnoldi, and to EH. lucasiws. According to A. v. Schulthess

(Societas Entomol., xxv, 1910, p. 24), Gribodo’s acwminatus is specifi-

cally distinct from de Saussure’s species, but the differences were

not stated.

H. de Saussure’s type (¢), from the “ Cape of Good Hope,” should

be at the Stockholm Museum.

much longer, as long as the thorax; parallel-sided in its basal third,

then suddenly widening to twice the width, the apical third also

parallel-sided, with distinct, median, longitudinal groove; in profile

straight in the basal half, rather strongly swollen and curved in the

apical half. Puncturation as in coarctatus, coarse and very dense on

head and thorax, the intervals smaller than the punctures; first and

second tergites with scattered, fine punctures.

“ Black, with abundant orange-red and pale yellow markings.

Head and thorax densely covered with long, yellowish-grey pile.

The following parts are orange-red: mandibles, labrum, clypeus, a

dot between the eyes, the basal half of the antennae as well as their

under side, the pronotum (which, however, is blotched with black in

the posterior corner), tegulae, scutellum, propodeum, a large spot

below the wings, the sides of the first tergite, the hind margin of the

second, tergites 3 to 6, and the legs. In addition, on the second

tergite a large, median [orange-red] spot (which may be absent),

connected with the apical band; also two large, lateral spots in the

anterior half of the tergite, often connected along the sides with the

apical band. The following parts are yellow: in the 2, the post-

scutellum, a narrow fascia at the apex of the first and second tergites,

and stripes on the anterior surface of the tibiae; in the g, the under

side of the scape, the prothoracic lobes, the hind margin of the pro-

notum, two spots on the scutellum, the postscutellum, the lower

corners of the propodeum, the apical margin of all tergites and sternites,

two small, rounded spots anteriorly on the disk of the second tergite,

and the anterior surface of all femora and tibiae.

“Length of body: 16 mm.”

Described on one male and two females from “ Kapland ” (probably

Cape Province).

The species is unknown to me. Since it is compared with H#.

coarctatus, we must assume that the hind margin of the second segment

is duplicate and that it consequently belongs in Humenes proper.

It appears to be quite distinct from any of the species which I have

seen, although it does not seem feasible to include it in the key on the

strength of published characters. Its closest ally is evidently £.

acuminatus, but the size (although clearly based upon the total length,

which varies considerably with the retraction of the posterior segments)

is much too large for that species.

526 Annals of the South African Museum.

Subgenus AFREUMENES, J. Bequaert.

Eumenes melanosoma, H. de Saussure.

The outstanding morphological feature of this species is the presence

of a sharp, vertical carina shortly before the hind margin of the meso-

pleura. Although this peculiarity is not mentioned in the description

of H. sulcigastra, and I have had no occasion to examine the type,

I have little doubt that species is the typical colour form of EL. melano-

soma. The various structures pointed out by Gribodo are present in

melanosoma, which was originally described by error as of Java. As

a matter of fact, it has never been found outside the African continent,

where it occurs south of 12° N., extending in the west to 12° S., and

in the east at least as far as Durban.

The morphological characters of the species have been described

and illustrated in my paper of 1918. It may still be added that the

apex of the second tergite is not duplicate; but the punctate, pre-

apical area is separated from the smooth, impunctate, depressed,

terminal margin by a fine, transverse, dotted line.

Several colour phases may be recognised. Although the extremes

are conspicuously different, there are many intergrades, so that it is

not always evident which varietal name to use. Possibly some of the

transitional forms may be due to hybridism, as several phases often

occur in the same geographical area. They are by no means as

clearly defined as in the case of #. maaillosus.

to specimens in the Carnegie Museum) and Abyssinia (sulcigastra,

Owing to the total absence of yellow on the thorax, I prefer to include

it among typical melanosoma. Some specimens have hardly a trace

of ferruginous, while others are distinctly blotched with that colour.

In the males of Katanga, the clypeus is reddish without pale yellow,

in those of Natal it is almost entirely ivory-white.

This extreme melanistic form is so slightly different from the typical

phase that it hardly deserves a name. A. v. Schulthess has recorded

it from Togo, Cameroon, the Belgian Congo, Nyasaland, and Zanzibar.

the Carnegie Museum), and Fernando Po (several specimens at the

British Museum, including one of the “ types ” of #. moserz), through-

out the Belgian Congo (as far south-east as the Manyema), to Uganda

(numerous specimens in the British Museum), and [ala in the Maramas

district, Kenya Colony (S. A. Neave, Brit. Mus.).

There are also at the British Museum several specimens from north-

east Rhodesia and Mashonaland which are evidently transitional

between the typical form and the var. decopiens.

extending from Kenya Colony (Voi.—Brit. Mus.) to Zululand. West-

ward it barely enters the north-eastern Belgian Congo (on the Lower

According to Gerstaecker’s original description, longirostris is black

and ferruginous red, with a yellow spot on each side of the propodeum,

a pair of elongate yellow spots behind the middle of the first tergite,

a yellow, apical margin on the first tergite, and an interrupted, yellow,

transverse fascia at the apex of the second tergite. Among the

specimens here referred to longirostris, the male from Lubumbashi,

Katanga, comes quite near this description, but the interrupted, pale

fascia at the apex of the second tergite is exceedingly narrow; the

clypeus is totally yellow. The female from the same locality is quite

similar, but has a reddish-brown clypeus, and the second tergite lacks

the apical fascia. In the male of Acornhoek there is a small, yellow

spot on each side of the pronotum ; while the male of Mfongosi has,

in addition, two yellow dots on the scutellum, an interrupted, yellow

band on the postscutellum, and traces of preapical, lateral, yellow

spots on tergites 3, 4, and 5.

In coloration this interesting form is a perfect mimic of the typical

colour phase of H#. lepeleteriz. It is apparently quite rare and peculiar

to the coastal districts of equatorial East Africa. A. v. Schulthess’

specimens were from Daressalaam, while EL. zanthaspis was described

from Kibonoto, on the lower slopes of Mt. Kilimanjaro. At the

United States National Museum I have seen a male from Jombene

Hills, Kenya Colony (Chanler-Hohnel Expedition), which is here some-

what more fully described.

Black, with abundant bright yellow markings as follows: clypeus ;

mandibles; a lozenge-shaped spot between the antennae; sinus of

eyes; outer orbits; scape quite broadly below; pronotum (except

for a black, triangular spot on each side before the wings) ; scutellum

(except posteriorly) ; major part of mesopleura ; propodeum (except

for a black stripe on the median groove) ; outer side of fore femora,

of all tibiae, and of fore and middle basitarsi; an elongate spot on

each side beyond the middle and a narrow apical margin on first

abdominal tergite ; broad, preapical bands on tergites 2 to 5, inter-

rupted in the middle ; also a broad, somewhat triangular spot on each’

side in the basal half of second tergite; and small, lateral spots on

sixth tergite. Major part of antennae, anterior face of thorax, tegulae,

legs (except where yellow), sides of first abdominal segment (more

extensively before the yellow, apical margin), sides of second tergite,

and all the sternites, more or less ferruginous ; this colour also suffuses

the black of the pleura. Wings subhyaline, tinged with amber yellow.

Length (h.+th.+t. 1+2): 13 mm.

Another male from Kibwezi, Kenya Colony, 3000 ft., April 2-4,

contains additional specimens from Sierra Leone, the Gold Coast,

particulars, such as the shape of the antennal hook. The female is,

so far as I know, undescribed.

Female (undescribed).—Head rather flattened, seen in front slightly

wider than high. Clypeusa little longer than wide, elongate hexagonal,

very slightly and evenly convex ; the anterior, free portion nearly as

long as the basal, interocular part; the apical margin about one-half

the total width of the clypeus, very broadly and arcuately emarginate,

with distinct and rather sharp edges. Vertex without fovea. Ocelli

slightly raised and very bluntly carinate between the antennae. Hyes

bare, but slightly farther apart on the vertex than at the clypeus.

Vertex and temples quite narrow, margined behind with a continuous,

sharp rim. The shape of the mandibles is characteristic; they are

moderately long and slender, decussate, straight, slightly curved at

the blunt apex, with three narrow notches along the inner margin ;

of the three teeth thus defined, the first (nearest the base, but placed

about midway) is small and blunt; the two following are very broad,

flattened plates, the second being about twice as long as the third ;

beyond the third, the inner margin forms a much narrower plate

extending to near the apex; the inner margin is set off by a carina

accompanied by a deep groove, which bears numerous stiff setae ;

shortly before the apex the setae are so numerous as to form a brush ;

owing to the development of the lamellar teeth, and also to a slight

widening of the outer margin, the mandible is nearly as broad in its

apical half as at the base. Third segment of maxillary palpi short,

only half as long as the second, and about the length of the fourth

and fifth. Antennae rather short, moderately swollen toward the

apical half ; segments—6 and 7 longer than wide, 8 almost square, 9 to

11 slightly wider than long, 12 a little longer than wide at base. Thorax

elongate globular, nearly subglobular, shorter and more convex than

in the other Ethiopian species of the subgenus Delta; but little

longer than high in profile or than broad seen from above. Pronotum

squarely truncate; the anterior margin rimmed throughout with

a fine, raised line; on the sides, below the humeral angles, there is at

first only a blunt ridge, but in the lower part this becomes a wavy

carina. Humeral angles broadly rounded off, the pronotum but little

narrowed anteriorly. Mesonotum slightly longer than wide, with a

fine, median, impressed line in its anterior half, generally hidden under

the appressed pilosity. Scutellum and postscutellum evenly and

slightly convex, forming a continuous curve with the mesonotum ;

the scutellum partly and the postscutellum entirely within the posterior

slope of the thorax; neither of them show a median raised line or

depression. Propodeum very short and moderately convex; seen

from above hardly longer than postscutellum, rounded off, without

ridges or projecting angles on the sides ; in the upper half it is merely

divided by a fine, median, longitudinal, impressed line ; in the lower

half it is very broadly and shallowly excavated toward the base of the

abdomen ; just above the valvulae the sides are conspicuously com-

pressed into a short ridge, ending posteriorly in a sharp point. Meso-

depressions, which are, however, quite pronounced. Legs slender, as

usual. Venation of wings of the ordinary Eumenes type; the third

cubital cell rather longer at the cubital vein than usual. First abdom-

inal segment very long and slender, more so than in the other African

species of the subgenus Delta; nearly as long as head and thorax in

profile ; about five times as long as wide at apex, seen from above ;

in profile strongly curved and quite gradually and slightly swollen

from the base to before the apex; seen from above it very gently

widens posteriorly (even more evenly than in #. lepeleteri), the apex

being not much over twice the width of the base; dorsally it is uni-

formly convex, without any trace of groove; the spiracles are not in

the least visible from above, and they are just barely raised on the

sides. Second segment elongate oval and slightly depressed, about

equally convex dorsally and ventrally, nearly one and one-half times

as long as high in profile, and but little longer than wide seen from

above ; basal neck long, a little over half as wide as the apex of the

first segment, as conspicuous as in many species of Zethus ; apical

margin simple, depressed ; sternite more convex than usual, slightly

flattened at base. Head and thorax quite densely covered with large

but rather shallow punctures, giving it a minutely reticulate appear-

ance; vertex, temples, tegulae, and epicnemial depressions for the

fore and middle legs nearly impunctate; the sides of the propodeum

also with rather sparse and small punctures; the anterior margin of

the scutellum with a smooth area, which extends somewhat backward

in the middle; clypeus with few, very scattered, small punctures,

which are somewhat more distinct in the basal half. Abdomen

is densely and uniformly covered with microscopic punctures. Head

and thorax densely covered with short, greyish-white, somewhat

matted pile, with a slight silvery sheen, more noticeable on the clypeus ;

abdomen and legs nearly bare, with a faint greyish bloom.

Black, with indefinite ferruginous brown blotches on mandibles,

base and under side of antennae, clypeus, pronotum, tegulae, pleura,

scutellum, propodeum, sides of first abdominal segment, base of

second, succeeding sternites, last tergite, and legs. The ivory-white

markings are reduced to a short line along the outer orbits above, two

small spots before the apex and a narrow line on each side of the

apical margin on the first tergite, and a quite narrow preapical fascia

on the second tergite, generally interrupted in the middle. Wings

faintly smoky anteriorly, somewhat brownish in the costal cell, the

radial cell more purplish. The extent of the ferruginous and ivory-

white markings varies, not two of the five females which I have seen

being alike in this respect.

Length (h.+th.+t. 14+2): 14:5 to 16 mm.

Male.—Clypeus much longer than wide; the anterior, free portion

distinctly longer than the basal, interocular part; the apical margin

about one-half the total width of the clypeus, broadly and arcuately

emarginate, with sharp edges. Posterior ocelli about twice as far

apart as from the inner orbits. LHyes a little less than twice as far

apart on the vertex as at the clypeus. Mandibles of more usual

shape; the lamellar teeth along the inner margin much narrower than

in the female; the conspicuous row of setae and preapical brush

absent. Antennae moderately and quite gently swollen toward

apical half; segments—7 and 8 slightly longer than wide, 9 and 10

nearly square, 11 and 12 longer than wide; last, hook-like segment

hunchbacked, shaped like a duck’s head in profile: the basal half

much swollen, the apical part very abruptly narrowed to a blunt

point, which fits in a shallow pit at the under side and about the

middle of the tenth segment. Last abdominal sternite uniformly

convex, smooth, impunctate. Clypeus either ferruginous and black

as in female, or more or less broadly margined with ivory-white ;

the inner orbits narrowly ivory-white from the clypeus to the bottom

of the ocular sinus. In one of the males from Zululand there is a

narrow ivory-white line along the posterior margin of the post-

scutellum. The remainder as in the female.

Length (h.+th.+t. 1+2): 12 to 15 mm.

In my Revision of the Vespidae of the Belgian Congo, I had reached

the conclusion that H. caffer (Linnaeus) was not morphologically

distinct from F#. campanifornis (Fabricius), and I regarded E. formosa,

H. de Saussure, as identical with L. caffer. Unfortunately I was un-

able at the time to examine South African specimens of caffer. I have

since found that the true H. caffer of the Cape differs in a number of

important particulars from the several colour phases of E. campani-

formis. The description and drawings which I gave in 1918 of the

morphology of #. caffer do not apply to that species, but to LH. campani-

forms (Fabricius). Itis therefore necessary to point out the structural

peculiarities of EL. caffer.

straight, with bluntly rounded edges. Ocelli in a flattened triangle,

the posterior ocelli a little farther apart than from the inner orbits,

about as far from the hind margin of the vertex as from the eyes.

Antennae moderately swollen ; segments—7 and 8 nearly square, 9 to

11 wider than long, 12 about as long as wide at base. Thorax elongate

oval, about one-third longer than high, somewhat longer than in

E. campaniformis ; the mesonotum conspicuously longer than wide.

First abdominal segment distinctly shorter than the thorax; its

general’ shape as in campaniformis, but of stouter build; in profile

its apical half is relatively more swollen as compared with the base ;

seen from above its apical, widened portion is not quite twice as long

as its greatest width and is parallel-sided, so that the passage to the

basal stalk is much more abrupt than in campaniformis. The broad-

ened part of the first tergite bears a few scattered, but distinct

punctures ; whereas in campaniformis it is almost impunctate, with —

very few, quite minute punctures. Second sternite normally convex.

The hind tarsi are about as long as the hind femur and trochanter,

but much longer than the tibia. The few differences from H. campani-

The Genus Eumenes, Latreille, in South Africa. 537

formis are slight and of degree only, and, were it not for the striking

characters presented by the male antennae and genitalia, one would

never feel quite certain of the specific distinction of the two forms.

The maxillary and labial palpi are more slender in HL. caffer than

in EL. campaniformis ; this is especially striking for the three basal

segments of the maxillary palpi, whose third segment is decidedly

longer than the three apical segments together.

Male.—The difference in the shape of the thorax also holds good

in this sex; but it is much less evident in the shape of the first

abdominal segment, which is more slender than in the female. The

antennal hook is slender, gradually tapering from a triangular base

to a long, very sharp, straight apex, reaching to slightly beyond the

middle of the tenth antennal segment; there is, however, no pit or

excavation of that segment to receive it. The antennal hook is in

general outline more like that of EZ. lepeleterw than E. campaniformes,

though somewhat more pointed than in the former. Gribodo (Mem.

“Ac. Sci. Bologna, Sc. Nat., (5), v, 2, 1895, p. 90) has correctly described

it. The male genitalia are strikingly dissimilar from those of HL. cam-

paniformis, E. lepeleteriz, and H. maxillosus, which is the more remark-

able since they are so much alike in the three last-named species. The

whole organ is quite thick and bulky, very wide seen in profile; the

penis is conspicuously narrowed beyond the swollen base into a slender

stalk and widens again into a terminal, long and broad, more or less

saddle-shaped plate, which is deeply emarginate at the apex.

Length (h.+th.+t. 1+2): 9,19 to20mm.; ¢,13to18mm. The

male is unusually stout in this species.

H. caffer appears to be restricted to South Africa ; with the excep-

tion of Potchefstroom, all the localities from which I have seen it are

south of the Orange and Vaal Rivers. R. du Buysson (Bull. Soc. Ent.

France, 1908, p. 134; in A. Chevalier, L’ Afrique Centrale Frangaise,

1908, p. 707; and Act. Sot. Linn. Bordeaux, Ixiv, 1910, p. 228) has

recorded it from the Atlantic coast of the Sahara as well as from the

central Sahara (Oued Tidek; valley of Taghazi, north of the Air) ;

but I have little doubt that the specimens in question were mis-

identified. Most probably they belonged to some colour phase of

EL. arbustorum (Panzer).

I have seen specimens from the following localities :—

feet, Ceres district (R. E. Turner), Brit. Mus. ; Willowmore, 1 9 and

1 3 (H. Brauns). )

In coloration E. caffer appears to vary but little. It is black with

the following bright yellow markings: clypeus (in both sexes); the

centre of the face between the antennae; the inner orbits from the

clypeus to half-way in the sinus of the eyes; basal half of mandibles,

gradually fading into the ferruginous apex; under side of scape ;

a narrow line along the outer orbits in the upper part of the temples ;

pronotum; upper plate of mesopleura, continuous with a large,

triangular spot on the lower plate; a very wide band across the

scutellum ; postscutellum except anteriorly ; propodeum except for

a broad, median stripe; posterior half of tegulae; four spots on the

swollen portion of the first tergite, two above the spiracular pro-

tuberances and two before the apex extending laterally to the edges,

but not connected medially ; the remainder of the abdomen, except

for an elongate, median, black spot on the basal half of the second

sternite (drawn out into a point posteriorly) and a black cross over

the second tergite, the cross gradually narrowing and fading away

on the succeeding tergites; an elongate spot on middle coxae; the

under side of fore and middle femora ; the upper side of all tibiae and

of fore and middle basitarsi. The apex of mandibles, the basal half

of the flagellum and a line on the under side of its apical half, the under

side of the broader, apical half of the first segment, the sides of second

tergite and sternite near the base, and the legs wherever not yellow,

are ferruginous red. The wings are subhyaline, with a yellow, amber-

coloured tinge and a slight, purplish black spot in the radial cell. The

two sexes are coloured almost exactly alike.

It is possible that there exists in the coastal region of the Cape

Province a colour phase of H. caffer similar to E. campaniformis var.

pulcherromus. See the discussion of that form, p. 551.

Eumenes campaniformis (Fabricius).

(Text-figure 11.)

The structural characters of this species have been described and

illustrated in my Revision of the Vespidae of the Belgian Congo

(1918), under the heading LE. caffer (p. 69, figs. 50-55). It was believed

at the time that caffer and campaniformis were but two colour phases

The Genus Eumenes, Latreille, in South Africa. 539

of the same species. They are, however, morphologically quite

distinct, as I have shown above.

As E. campamformis assumes several colour phases, some of which

are deceivingly similar to forms of other species, its chief characters

may be pointed out. In the female the head as seen in front is nearly

one-fifth broader than high ; the eyes are but little farther apart on

the vertex than at the clypeus; the posterior ocelli are much less

than twice as far apart as from the inner orbits; the sides of the

propodeum are completely rounded off between the dorsal and the

ventral areas; the first abdominal segment is intermediate in shape

between that of H. maxilosus and LE. lepeleterw ; 1t approaches that

of the former, though it is more slender, being about as long as the

thorax ; seen from above it is distinctly divided into a basal, stalk-

like half and an apical, broader portion, both with subparallel sides

and the passage between the two rather abrupt; the apex does not

widen out as in F£. maxillosus, and is about one-fourth of the total

length of the segment ; second sternite normally convex in the centre.

The hind tarsi are about as long as the hind femur and trochanter.

In the male the first segment is somewhat more slender; the hook-

like segment of the antennae approaches that of #. mazillosus, being

in profile slightly thickened beyond the apex; but seen from above

it is not widened in its apical half; it is rather abruptly and sharply

pointed at the apex, which rests in a small excavation on the under

side, near the extremity of the tenth antennal segment; the eyes are

distinctly nearer at the clypeus than on the vertex, and the posterior

ocelli are about twice as far apart as from the inner orbits. An

examination of much additional material has convinced me that the

difference in the female antennae, which I had formerly relied upon,

is imaginary. Neither is there any reliable difference in the develop-

ment of the groove-like depression of the last abdominal sternite in

the male.

EH. campaniformis and its several colour phases have a wide range

over the Ethiopian, Oriental, Malayan, and Papuan regions, as far

as Mesopotamia, southern China, Formosa, New Guinea, the Solomon

Islands, and Queensland. In Africa it is known with certainty from

Lower Egypt and the Senegal River to Angola in the west, and to the

Orange Free State and Natal in the east. It is seemingly absent

from the Cape Province, where it appears to be replaced by L. caffer,

although the ranges of the two species overlap in the Orange Free

State and southern Transvaal (see the map in my paper of 1918,

p- 71, which should, however, be amended to cover the whole of

540 Annals of the South African Museum.

Egypt, Mesopotamia, and southern Persia, and to exclude south-

western Africa and the Cape Province). It is not known from the

Malagasy region.

If we regard campaniformis and esurivens as mere colour phases of

one morphological type, the specific name should be campaniformas,

which is much older than esuriens.

My former treatment of the colour phases of £. campaniformis (1918)

was wholly inadequate, owing to the restricted material of which I

disposed and to my erroneous interpretation of H. caffer (Linnaeus).

The morphological species campaniformis evidently presents many

colour phases, the study of which is fully as interesting as those of

E. mazxillosus. Since several of them occur in South Africa, I have

thought it appropriate to present a revision of all the variations.

As indicated below, there are probably a number of additional colour

phases worthy of recognition, but as I have generally not seen them,

they are left nameless for the present. There is always a possibility

that the types might prove to be morphologically distinct from

E. campaniformis. Moreover, the distribution of the several colour

phases of #. campaniformis can hardly be worked out at present :

they have been too frequently confused with one another and with

similar colour variations of allied species (especially H. lepeleterd).

The name campaniformis was originally proposed by Fabricius for

a wasp of Australia, described as follows: “ Black, variegated with

yellow ; petiole of the abdomen ferruginous, black at apex and with

two yellow spots. A little smaller than the preceding species [i.e.

542 Annals of the South African Museum.

E. arcuata]. Antennae ferruginous, brownish at apex. Head black,

the front and the orbits of eyes yellow. Tongue ferruginous. Thorax

black ; the anterior lobe, a large spot below the wings, and a small

dot before the wings, yellow. Scutellum yellow, with a black band.

Thorax below the scutellum yellow, with a black median groove.

Petiole of abdomen elongate, curved, ferruginous, black at apex, on

either side with a yellow dot. Second segment the largest, with two

basal spots and the margin yellow. Remaining segments with yellow

margin. Legs yellow.” The type is in the Banks Collection, at the

British Museum.

Typical campaniformis ditters but little from the var. esuriens.

The most important point is that the ferruginous base of the second

tergite is extensively or completely replaced by yellow; generally,

too, the transverse black band of the second tergite is broader and

connected on the middle line with the base of the tergite (so as to

form a black inverted T); while the yellow apical band of the first

tergite is interrupted in the middle, the ferruginous colour is much

reduced on the thorax, being replaced either by black or by yellow.

Length (h.+th.+t. 1+2): 9,15 to17 mm.; g, 14:5 mm.

This colour phase is found in the Malayan and Australian regions.

I have seen it from Java, the Philippine Islands, Queensland, and

Yule Island, near New Guinea.

E. urvillei, de Saussure (Et. Fam. Vesp., i, 1852, p. 59, 23), appears

to have been based upon two distinct colour forms. The male of

Triton Bay, on the coast of New Guinea, evidently does not differ

from typical L. campaniforms. The female of Banda Island, how-

ever, is said to have the second tergite entirely ferruginous at base,

without yellow spots, but with a broad yellow apical band, interrupted

in the middle; the mesonotum is black and the propodeum spotted

with ferruginous and yellow ; there are some other points, too, which

seem to indicate that this may represent a peculiar colour phase

worthy of recognition. The absence of yellow spots at the base of

the second tergite excludes #. edwardsw, H. de Saussure. I have,

however, as yet seen no specimens agreeing with the description. The

types of H. urviller should be at the Paris Museum.

This was first described by Fabricius from India, in the following

terms (so far as coloration is concerned) : “ Ferruginous, with yellow

abdomen; the curved petiole and first segment ferruginous, the

former with yellow margin, the latter with black margin. Head

yellow ; the antennae ferruginous with brown apex. Thorax yellow,

the dorsum and hind part ferruginous. Scutellum yellow. Petiole

of the abdomen ferruginous, yellow at the apex and slightly black

before the apex. Second segment ferruginous, with black margin ;

the remainder yellow. Wings darkened. Legs yellow, with ferru-

ginous femora.’ There are some evident errors in this description :

the statement that the second segment has a black margin is un-

doubtedly due to an oversight, as the black band runs over the middle

of the tergite. If one allows for this, de Saussure’s interpretation of

esurtens is quite correct (his figure, however, is misleading and does

not agree with the description in several important particulars), and

I have seen specimens of both sexes, from India (Bombay, Abu, etc.),

which have this coloration. They may be described as follows :—

Mostly yellow and ferruginous-red ; the black being restricted to

a broad band across the vertex (including the ocelli), a narrower band

on the occiput and outer part of the temples, an anterior and two

lateral spots on the mesonotum, propleura, the base of the first seg-

ment, and a black, transverse band before its apex dorsally, a trans-

verse band. about the middle of the second tergite, the base of the

succeeding tergites and apex of the last, and the apical two-thirds

of the middle and hind tarsi; the apical half of the flagellum is brown-

ish on the upper side. The following parts are ferruginous: major

part of antennae (the scape yellow beneath), apex of mandibles,

mesonotum (except for the black spots and hind margin), scutellum,

tegulae, sternum, metapleura, and propodeum (the propodeum dorsally

with a small yellow spot on each side, close behind the wings), first

segment (except for the black base and preapical band and the broad,

yellow apex dorsally), the basal half of the second segment, the legs

(except for the black, apical two-thirds of the middle and hind tarsi,

and much yellow on the tibiae and on the upper side of the anterior

femora). All other parts of the body yellow, and the posterior part

544 Annals of the South African Museum.

of the second tergite is continuously so, without black division or

interruption in the middle. There are no yellow spots on the ferru-

ginous base of the second tergite. The wings are subhyaline, with

amber-yellow tinge and with a darker, somewhat purplish spot in the

radial cell.

The var. esurvens appears to be restricted to India proper, but it

has been so commonly confused with the var. gracilis and typical

campantformis that its distribution cannot be correctly given. I

have never seen it from the African continent. What I had recorded

as esuriens from the Belgian Congo (Stanleyville and Bogoro) (Bull.

Amer. Mus. Nat. Hist., xxxix, 1918, p. 73) does not belong to the

typical colour phase, but is described in the sequel as var. marshall.

The specimens described by H. de Saussure (Ht. Fam. Vesp., i, 1852,

pp. 56 and 57) as #. esurvens var. B and var. C, in which the meso-

notum is spotted with yellow or is almost completely yellow, probably

represent a colour phase worthy of a varietal name. As I have seen

no such specimens as yet, I refrain from naming it. The variety C is

stated to have come from Persia ; it is quite possible that all Persian,

and perhaps Mesopotamian, specimens are of that type.

black base; as a rule the yellow only is visible. Anus ferruginous.

Under side of the abdomen russet, the segments margined with yellow,

and a lozenge-shaped black spot, often indistinct, on the second

sternite. Legs ferruginous, the tip of the tibiae yellow, as are also

nearly the whole fore pair of legs. Wings ferruginous along the costa ;

veins ferruginous or brown; a brown spot in the radial cell. Male.—

Clypeus without emargination. The first segment and the apex of

the antennae black on the upper side, except on the two last segments.

Mesothorax entirely black. The yellow margins of the abdominal

segments narrower than in the female, so that the black base is distinct. —

Anus black. Legs spotted with black. The remainder as in the

female.’ The author also notes variations of the female, in which

the yellow spots of the second abdominal segment are absent, the

base of this segment is black, and the stripe which divides the pro-

podeum is also black; mesonotum entirely black; the black band

of the second abdominal segment widened in the middle; the two

yellow spots of the petiole fused into an apical band. There is a

corresponding variety of the male without yellow spots on the second

segment. In addition, de Saussure quotes Savigny, Descript. de

PEgypte, Atlas, Zool., Ins. Hym., 1812, pl. vii, fig. 6 (93), as repre-

senting gracilis.

I have quoted this description at length because it clearly shows

that the name gracilis should be used for a colour phase which merely

differs, as de Saussure states, from the var. esurzvens “in the meso-

notum being entirely black or with but a small russet spot, in the

black bands of the abdomen being broader and darker, and in the

black spot of the antennae.” There may or may not be two small

yellow spots on the ferruginous base of the second tergite. R. du

Buysson (Abh. Senckenberg. Naturf. Ges., xxxiv, 2, 1911, p. 230)

seems to imply that the var. gracilis is strictly African (Egypt, Senegal,

Congo, Sudan, etc.), whereas it really is the more common form in

southern Asia. I have seen specimens which agree well with de

Saussure’s account, from Lower Siam (United States National

Museum), Mombasa, Kenya Colony (G. M. Allen and G. Brooks—

Mus. Comp. Zool., Cambridge), Fayum, Egypt, and Formosa. It is

at present impossible to accurately define the area over which gracilis

is found on the African continent. I have not seen it from the Belgian

Congo ; all the specimens I had referred to gracilis in Bull. Amer. Mus.

Eumenes elegans, H. de Saussure, Et. Fam. Vesp., i, 1852, p. 58 (9),

pl. xi, figs. 3 and 3a, was described from Dyjidda, Arabia, and the

Kast Indies (in the Paris Museum) as follows: “ Yellow with the

vertex, mesothorax, and a band on the second segment of the abdomen,

black. Wings brown. Female: length, 20 mm.; spread of wings,

38mm. Head broad, ferruginous, darkened on the upper side toward

apex ; under side of the head, and even the sinus of eyes, very villose.

Thorax villose, ferruginous; mesothorax [=—mesonotum] black.

Petiole [=first abdominal segment] ferruginous, black at base, its hind

angles yellow. Abdomen ferruginous; the second segment margined

with yellow and with a broad black band gradually passing into the

ferruginous; under side of the segments darkened. Legs ferruginous.

Wings hyaline, ferruginous at the base, brown with violet reflections

in their external two-thirds. This pretty species much resembles

H. esuriens and allied species, but is easily distinguished by the

strongly smoky wings, which are somewhat violaceous.” £. elegans

has never been properly recognised. If it is indeed structurally like

E. campaniformis, it should represent a quite peculiar colour phase

of that species. It is, however, possibly a variety of HE. lepeleteric.

This was quite briefly defined by H. de Saussure as follows: “ Black,

ornamented with yellow. Abdomen bearing a black cross. Size of

E. campaniformis, and quite closely allied to that species, from which

it differs in the following characters: Antennae brown. Tegulae

ferruginous, with a yellow spot. Petiole [=first abdominal segment]

swollen from the middle on, thence uniformly wide in its entire posterior

part, ferruginous, with two yellow spots at the apex, between which

one sees a black spot shaped like a rounded lozenge, and with two

yellow dots in its middle. Abdomen perfectly oval, yellow with a

black cross. Legs ferruginous; tibiae yellow. Pleura yellow, with

an oblique, black band. The remainder as in campaniformis.” The

type came from the Congo, and is at the British Musuem.

southern half of the African continent, and as such deserves a more

complete description.

Black, abundantly marked with bright yellow as follows: clypeus

entirely (in both sexes), a tinge on the inner half of mandibles, lower

half of face (including most of the sinus of the eyes), broad outer

orbits, pronotum, scutellum and postscutellum (except along the

anterior and posterior margins), major part of propodeum (divided

by a narrow, median, black stripe), mesopleura, a spot on the tegulae

posteriorly, two spots (widely separated) before the apex of the first

abdominal tergite, the second tergite except for a wide, black cross,

the posterior half of the second sternite, most of the remaining seg-

ments of the abdomen (the yellow more or less distinctly interrupted

on the tergites by the continuation of the black cross of the second

tergite), the under side of the fore femora and the under side of all

the tibiae. The following parts are ferruginous-red: most of the

mandibles; the antennae (brownish in the apical half on the upper

side); part of tegulae; mesosternum; first abdominal segment

(except for a short, black base and a black, preapical spot between the

yellow spots, either lozenge-shaped or extending laterally into a cross

band); the basal half of the second sternite; the extreme base and

sides of the second tergite ; and the legs (except where yellow). Wings

subhyaline, amber-yellowish in the subcostal and more ferruginous in

the costal cell; a faint, somewhat purplish spot in the radial cell.

Both sexes are practically coloured alike.

Length (h.+th.+t. 14+2): 2, 14 to 18-5 mm.; 3, 13 to 16-5 mm.

The similarity in coloration of LE. campaniformis var. formosus and

the typical colour phase of HL. lepeleteria is most deceiving, and since

both often occur in the same district, they are generally confused in

collections. Probably most of the South African records of E£.

lepeleterw published in the literature were based upon specimens of

jformosus. In the male, the distinction is relatively easy owing to the

different shape of the antennal hook. In the females, however, one

must rely upon the shape of the first abdominal segment as seen from

above.

The var. formosus is common on the Lower Congo, but I have not

yet seen it from Katanga.

Afemale from Abyssinia (Magretti Coll.), at the UnitedStates National

Museum, differs from the above description of formosus in having a

comma-shaped yellow mark on each side of the anterior half of the

mesonotum, the two marks being separated by a ferruginous spot.

Perhaps it represents a peculiar colour phase of north-eastern Africa.

Eumenes campamforms var. rhodesiensis, new variety.

Female.—An extreme xanthic colour phase of E. campaniformis.

Head, thorax, legs, and wings are coloured as in the var. formosus,

de Saussure ; but there is a narrow, yellow line on each side of the

mesonotum, along the margin, just before the tegulae. The abdomen

is almost completely bright yellow: the first segment is black at the

extreme base, somewhat more extensively on the sternite, and the

tergite has a black, elongate spot over the middle of the apical, dilated

portion ; the remainder of the first segment is ferruginous-red except

for a long, yellow spot on each side of the black mark in the apical,

dilated portion; these yellow spots are much widened laterally in

their posterior half. The second tergite is yellow, with a median,

longitudinal, more or less spear-shaped, black mark, forming in the

basal third a stripe which is angularly dilated in the middle and tapers

out in a long point posteriorly.

This colour phase has been fully described in the paper quoted. It

differs mainly from the var. formosus in lacking the large, triangular,

yellow spots at the base of the second tergite, so that the abdomen

is not yellow with a black cross; the second tergite is more or less

extensively ferruginous over the basal third. Frequently too the

yellow markings are somewhat reduced on thorax or abdomen, but

they are always much more abundant than in the var. rendalli, as

there is a yellow, broadly interrupted band at the apex of the second

and succeeding tergites.

I have received a pair from Dr. Brauns marked as types of “ £.

lepeleteri, var. marshallc, A. v. Schulthess,’ but, so far as I can dis-

cover, this name has not been published. The shape of the first

abdominal segment, as well as of the male antennal hook, leave no

doubt to my mind that these specimens should be regarded as a

variety of L. campamformis and not of EL. lepeleteria.

I suspect that the specimens from Katanga (between Mufungwa and

Kayumbe; between Shawa and Kundiganga ; and Kabinda), recorded

under the name #. mazillosus var. pulcherrumus by Schouteden (Rev.

Zool. Afric., vi, 1919, p. 174), are #. campaniformis var. marshalls.

The var. marshalls is quite similar in livery to the wasp described

by A. v. Schulthess under the name Humenes mazillosus var. pulcher-

ramus. Since, however, I am as yet undecided as to the exact status

of pulcherrumus, the use of that name for the Central African form

here called marshalls might be the source of much confusion.

This form was originally described upon eight females from “ East

Africa from the equator to Natal.” In the material before me there

are three specimens which were identified as “ H. maxillosus pulcher-

rumus”’ by Dr. A. v. Schulthess and bear a “type” label. Of these,

one female of Algoa Bay (H. Brauns) and one female of Roode Poort,

neat Johannesburg (G. Kobrow), are in Dr. H. Brauns’ collection ;

while one male of Estcourt, Natal (HK. Haviland), was received from

the South African Museum. Obviously, however, these three speci-

mens were not before the author when he drew up his description,

and are therefore not true types. According to the labels they were

identified in 1911. Moreover, A. v. Schulthess states in the original

550 Annals of the South African Museum.

account that the male was unknown (and I am not aware that it was

ever described in print); neither does he include the Transvaal and

Cape Province in the distribution. J must emphasise this, because an

examination of the real types, used for the original description, might

well lead to different conclusions.

The problem is further complicated through the fact that these

three specimens, although practically coloured alike, appear to belong

to two species upon morphological grounds.

The male of Estcourt and the female of Roode Poort are structurally

like £. campaniformis, and I have little doubt that they belong to that

species. They have the same shape of the first abdominal segment,

head, thorax, and hind tarsi in the female. Whereas the antennal

hook and genitalia of the male are those of #. campaniformis, and not

of £. macullosus.

The coloration of these two specimens 1s as follows :—

Female.—Black, extensively marked with ferruginous and bright

yellow. Mandibles (except the black tip), basal half and under side

of antennae, tegulae, first abdominal segment (except for the black

base, continuing as a median stripe ventrally, and a black, mushroom-

shaped spot at apex of tergite), basal third of second tergite (except

for the black neck), the sides of second sternite quite broadly (the

black forming a large T), the tip of abdomen diffusely, and most of the

legs, bright ferruginous-red. The following parts are yellow: clypeus

(except for narrow, black margins along inner orbits) ; the lower half

of the front (except for black spots above the base of antennae) ; outer

orbits narrowly above; anterior half of pronotum; a large spot in

upper part of mesopleura extending below the suture between the

two plates; a broad, transverse band on scutellum; posterior half

of postscutellum ; a large, elongate spot on each side of propodeum ;

a preapical spot on each side of first tergite; broad apical bands on

tergites 2, 3, and 4, very widely interrupted in the middle; indefinite

spots on fifth tergite ; an apical band on second sternite; and outer

side of all tibiae and of fore femora. Wings subhyaline, with amber-

yellow tinge, especially in anterior half; the radial cell somewhat

cloudy and purplish.

Length (h.+th.+t. 142): 17-5 mm.

Male.—Almost exactly like the female; the yellow markings some-

what more pronounced behind the fourth abdominal segment.

Length (h.+th.+t. 1+2): 17 mm. ;

I have seen three other females from Natal(Hstcourt and Clairmont),

which agree in every structural detail with the specimen from Roode

Poort and are coloured exactly like it. I have no doubt that all

these five specimens represent a colour phase of LE. campaniformis,

which differs only from the var. marshalli in the yellow markings being

more extensive on the abdomen. If, as I surmise, A. v. Schulthess’

original types of Hast Africa belonged to the same colour phase of

E. campanifornus as here described, it is quite probable that marshallr

will be regarded as a synonym of pulcherrumus.

I should have felt no hesitation in doing so, were it not for the

female from Algoa Bay. That specimen, although coloured nearly

exactly like the one from Roode Poort described above, has a quite

different aspect. The head is about as high as broad; the posterior

ocelli are nearly as far from the inner orbits as from each other; the

thorax is rather short and broad; the first tergite, though in outline

like that of £. campaniformis, is relatively broader behind ; the second

sternite is normally convex ; the hind tarsi are but little longer than

the hind femur and trochanter; the sides of the propodeum are

completely rounded off. Length (h.+th.+t. 1+2): 20mm. I feel

reasonably certain that this specimen is not a colour phase of £.

macxilosus. Quite possibly it is a mere robust variation of EL. cam-

paniformis. On the other hand, it reminds one a great deal of L. caffer,

and it is, of course, not impossible that HL. caffer presents a colour phase

of the pulcherrimus pattern. The discovery of the corresponding male

alone can solve the problem. I may also call attention to the fact

that no colour phase of genuine EL. campaniformis has as yet been

recorded from the Cape Province.

In the South African Museum there is a female, unfortunately with-

out locality, which I regard as belonging to the same form as the

female from Algoa Bay here discussed.

name rendalli is herewith restricted to the colour phase of campani-

formis represented by the female type.

The following description is based upon the female type: Head and

thorax, including propodeum, extensively ferruginous; the vertex

and hind part of the temples, the apical half of the flagellum above,

small spots on pronotum, mesonotum, the sutures of the thorax, and

a median band on the propodeum, black. Legs rufous-red. First

abdominal segment ferruginous, except for a short, black base and

a broad, irregular, black band in the widened part, before the apex ;

second tergite black, with ferruginous basal third and indefinite

ferruginous spots on the sides near the apical margin ; the succeeding

tergites black, with dirty yellow or orange apical margins; the

abdominal sternites are almost entirely ferruginous. Wings sub-

hyaline with amber-yellow tinge; the radial cell with a brown,

purplish spot covering the apical two-thirds. The face (including

clypeus) and outer orbits were evidently yellow in life, but they have

turned orange. Length (h.+th.+t. 1+2): 17 mm.

A male from Mlanje, Nyasaland, at the British Museum, agrees in

coloration with the type, and, since it possesses the characteristic

antennal hook of £. campaniformis, I regard it as the true male of the

var. rendallo.

I refer to the var. rendallc specimens from the following localities :—

Belgian Congo: Boma, June 15, 1915, 1 9 and 1 g (J. Bequaert) ;

—all at the Brit. Mus.

A male from Walikale, Belgian Congo, agrees on the whole with

rendall, but has the pronotum quite broadly bright yellow. It may

be regarded as a transition to the var. marshallo, from which it differs,

however, in having no other yellow markings on the thorax and in the

absence of yellow at the apex of the second tergite.

recognised it in a melanistic form of £. campaniformis, of the Congo

forest. An examination of de Saussure’s type, at the British Museum,

has, however, shown that the true EL. dyscherus is South American

and not African. Ina recent note (Bull. Brooklyn Ent. Soc., xx, 1925)

I regard H. chalicodomae, H. de Saussure, HL. centralis, P. Cameron,

and H. magnus, Bréthes, as synonyms of #. dyscherus.

The melanistic Congo colour phase of HE. campaniformis I have

named var. pseudodyscherus. It is mostly black. Mandibles, under

side of antennae, tegulae, propodeum, sometimes also pronotum and

mesopleura, first abdominal segment, sometimes base of second, and

legs are more or less spotted with ferruginous. Clypeus entirely (in

both sexes), a spot between the antennae, inner orbits below the sinus

of eyes, a narrow line along outer orbits, and spots on the outer side

of the tibiae, yellow. In the female, the anterior margin of the

pronotum is also yellowish. The wings are asin typical campaniforms,

subhyaline with amber-yellow tinge and a brown, purplish spot in the

radial cell.

rounded off between the dorsal and the ventral area; the first abdom-

inal segment is slender, as long as or slightly longer than the thorax ;

seen from above it very gradually widens from base to apex, and is

about four times as long as its greatest width; second sternite not

or scarcely depressed in the centre ; hind tarsi about as long as hind

femur and trochanter. In the male, the first segment of the abdomen

is, as a rule, more slender than in the female; the terminal hook of

the antennae is quite long and slender, very gradually tapering from

the base to the sharp, recurved apex, which rests in a pit on the

under side and at about the middle of the tenth antennal segment.

E. lepeleterw is distributed over most of the Ethiopian and Malagasy

regions, a large part of Arabia, Syria, and Egypt. It has also been

reported from Cyprus. In South Africa it appears to extend much

beyond the limits which I had traced on the map in 1918. It is

rather strange that I have not yet seen a South African specimen

Since this is a common South African wasp, it may be more fully

described.

Female.—Extensively ferruginous-red ; it might well be described

as a typical lepeleterii in which the yellow has been replaced by

ferruginous. The black markings are as follows: upper half of front ;

vertex ; temples; mesonotum; mesopleura (except for a rufous spot

in the upper half); metapleura; margins of scutellum and post-

scutellum ; a median stripe on the propodeum ; extreme base, under

side, and an elongate, spear-shaped spot on the posterior dorsal half

of the first abdominal segment; an elongate spot on the second

sternite ; a cross over the second tergite, the base of the succeeding

segments, and the under side of the hind femora in part. The yellowish

colour is usually confined to the narrow outer orbits (often orange)

and the lateral ridges which connect scutellum and postscutellum with

the base of the wing. Occasionally the lower inner orbits (from the

clypeus to the bottom of the ocular sinus), the very centre of the

clypeus, spots between the antennae, the extreme apical corners of

the first tergite, and the base of the fore tibiae may be yellowish. The

558 Annals of the South African Museum.

Wings are intensively amber-yellow, darkened and more purplish

toward the tip.

Male.—Agrees quite well with the female. Generally the clypeus

is entirely pale yellow, but I have also seen males in which it is

ferruginous (perhaps discoloured artificially). Often too there is a

short, transverse, pale yellow line in the centre of the pronotum, and

this may be faintly indicated even in certain females.

Length (h.+th.+t. 1+2): 9, 16-5 to 19 mm.; 3, 12 to 16-5 mm.

Originally described form Nubia, it occurs throughout Hast and

South Africa. I have also a pair from Fort Crampel, in the Ubangi

Territory of French Equatorial Africa, which are somewhat more exten-

sively black than usual, but still have subhyaline, amber-yellow wings.

While the female of Kaapmuiden agrees with the var. concinnus in

every respect, the two males of the same locality differ conspicuously

in having fairly large, pale yellow spots near the apex of the first

tergite, and on each side of the apex of the second tergite a transverse,

pale yellow spot. I have seen similar males from the Semliki Valley,

north-eastern Congo, and Lubumbashi, Katanga. At one time I was

inclined to refer them to the var. stuhlmanm. They possibly repre-

sent a distinct colour phase or perhaps are transitional between var.

concinnus and var. stuhlmanni. I do not wish to name them for the

present, since they might be £. lepeleterw var. thoracicus, Schouteden

lepeletera, of which it often assumes the several colour patterns. In

the female the head as seen in front is scarcely broader than high ;

the eyes are slightly farther apart at the clypeus than on the vertex,

and the posterior ocelli are about twice as far apart as from the inner

orbits; the sides of the propodeum are somewhat angular or even

faintly ridged between the dorsal and the ventral areas, especially in

the lower half; the first abdominal segment is rather stout, distinctly

shorter than the thorax; seen from above it is distinctly divided by

a slight contraction into a basal, stalk-like and a much broader, apical

portion ; the hind portion widens rather conspicuously at the apex,

where its width is variable, usually about one-third of the total length

of the segment; the second sternite is more or less depressed in the

centre, often quite deeply so, especially in large specimens ; sometimes,

however, the sternite is just barely flattened, and this is the usual

condition in the var. fenestralis, which is the smallest of all the colour

phases of maxillosus ; the anterior margin of the clypeus is, as a rule,

quite straight or faintly curved, either inwardly or outwardly; hind

tarsi relatively slender, much longer than hind femur and trochanter.

Almost all these characters hold in the male, which, in addition, may

be recognised by the peculiar hook of the antennae: it is very long and

thick, curved and somewhat contracted beyond the base, the terminal

half distinctly swollen in profile and widened seen from above; it

ends in a sharp, strongly bent apex, which reaches the base of the

tenth antennal segment ; it rests there in a broad and deep excavation

at the under side of the segment; the eyes are about equally far

apart on the vertex as at the clypeus; the posterior ocelli are quite

close to the inner orbits, being more than twice as far apart; the hind

(and also middle) tarsi are still more strikingly slender than in the

female. |

I have endeavoured to discover additional characters in the male

genitalia of L. campamnforms, EH. lepeleteru, and LE. macillosus, but

the differences appear to be so slight that they are of little specific

value. I have figured the penis of all-three species.

- The structural characters of EZ. mazillosus have been illustrated in

Bull. Amer. Mus. Nat. Hist., xxxix, 1918, p. 57, figs. 39, 40. It

should be noted, however, that the female antenna is there drawn

as 13-segmented, which is an obvious error; it possesses 12 segments

in this, as in all other Eumenes known to me.

The distribution of #. mazillosus is similar to that of E. campani-

formis, though more extensive, since it includes the whole of Africa

(except Morocco, Algeria, and Tunis), Madagascar, Arabia, Syria,

Mesopotamia, Persia, the Oriental region as far as southern China,

the Malay Archipelago, the Papuan region, and the north-eastern

half of Australia.

Over this vast area EH. mazillosus has produced more different colour

phases than any other species of Humenes. Every one of these colour

variations has a much more restricted range than that of the morpho-

logical species as a whole; yet generally two or more of them occur

together in the same region, so that I am unable to regard them as

geographically segregated races. Neither do they, as a rule, exhibit

gradual passage into one another at the limits of their respective.

ranges; such geographical intergradation is, I understand, the

essential criterion of the subspecific concept as used by students of

vertebrates. Nevertheless, as these several colour phases are morpho-

logically identical, 1t would, in my opinion, obscure the whole matter

to regard them individually as species, merely because they do not

fit the current conception of subspecies or races. There can be no

doubt that they are genetically quite closely related. There are many

other interesting problems suggested by the study of variation in this

species. I have briefly discussed them before,* and IJ shall not take

up the matter again for the present.

Since publishing my account of #. mazillosus in 1918, I have

examined much additional material, so that I am able to correct

and extend my conclusions in many particulars. The subjoined key

of the colour phases should replace my former attempt in that direction.

The main difference lies in the recognition by name of a number of

additional colour variations. As I have shown in the discussion of

E. campaniformis, the var. pulcherrumus, A. v. Schulthess, does not

belong to H. mazillosus, but (as far as Hast Africa is concerned) to

E. campaniformis. The distribution of the several extra-African

variations may be succinctly indicated. :

1. Var. corcinalis, Fabricius (Humenes circinalis, Fabricius, Syst.

Piezat., 1804, p. 286; Humenes latreiller butonensis, W. A. Schulz,

Waldo, Ann. Mag. Nat. Hist., (8), v, 1910, p. 43, 3). Region of Port

Darwin, northern Australia. I have examined the type at the British

Museum. It differs mainly from the var. latreadles in the markings

of the thorax being bright yellow and not orange. All the structural

characters of £. maazilosus are present.

6. Var. pyriformis (Fabricius) (Vespa pyriformis, Fabricius, Syst.

Entom., 1775, p. 371; Vespa petiolata, Fabricius, Spec. Insect., i,

1781, p. 467). Oriental region, from India to southern China.

W. A. Schulz, who examined the type of Vespa pyriformis at the

Copenhagen Museum, concluded that it was the same as Vespa

petiolata, Fabricius, as was suspected by de Saussure (Kt. Fam. Vesp.,

ili, 1856, p. 1383). Vespa petrolata, Fabricius, is of later date, and,

moreover, is preoccupied by Vespa petiolata, de Geer, 1778.

with the var. circinalis. An examination of the types, however, shows

that it is structurally distinct from EL. mazillosus. The same is true

for Humenes philantes, H. de Saussure, and Humenes fluctuans, H. de

Saussure, of which I have seen the types at the British Museum, and

also of Humenes bicinctus, H. de Saussure. EH. philantes, LE. bicinctus,

and H. macxillosus var. latrealec mimic one another in a most deceiving

fashion, presenting, together with many other Hymenoptera of that

region, a distinctively Australian and Papuan colour pattern.

This differs so little from the typical form that it hardly deserves

a name. Since it is the only colour phase found in Hgypt, certain

entomologists may wish to distinguish it; they should, however, be

aware that all transitions to the darker, typical mazillosus may be

found. Often the wings are more russet than black. I have seen

savigny? from the Fayum, Cairo, and Khartoum.

The name should be credited to Guérin and not to Spinola.

Congo. It extends, however, farther south-eastward than was

indicated on the map published in 1918 (p. 63, fig. 48).

This species does not occur on the African continent, being restricted

to the Seychelles and the Glorioso Islands. At one time I believed

that it was a colour phase of H. lepeleterm, but a study of specimens has

shown that it is morphologically quite distinct, and rather allied to

E. macxillosus.

It may be regarded as derived through oceanic isolation from £.

maxillosus. A parallel case is afforded by Ewmenes germaini, Lucas

(Bull. Soc. Ent. France, 1875, p. 76; Ann. Soc. Ent. France, (5),

vi, 1876, p. 300), of New Caledonia and the Loyalty Islands.

i. germaint has sometimes been regarded as a synonym of HL.

canthurus, de Saussure (which is but one of the colour phases

of #. maailosus); but on morphological grounds it is a

distinct species, as shown by a series of specimens at the British

Museum. The shape of the first abdominal segment is quite differ-

ent from that of H. mazillosus: seen from above it is distinctly

divided into a slender, basal half and a swollen, apical half about

three times as wide as the base; slightly beyond the middle the

first tergite bears on each side a very prominent, curved, spiracular

tooth. The head is conspicuously thickened, the vertex being

swollen and longitudinally furrowed behind; in both sexes the

posterior ocelli are farther from the hind margin of the vertex than

from each other. In the male the clypeus has a most extraordinary

shape, which may be regarded as an exaggeration of that of L. alluaudi :

the anterior portion is produced into a long, hatchet-like plate, the

thin, median margin being slightly and concavely arcuate, while the

projecting and divergent sharp edges are strengthened by a longi-

tudinal ridge. The antennal hook of the male is similar to that of

E. alluaudi. )

It is of interest that in both cases these precinctive species of

Eumenes replace what apparently is their ancestral form. For,

although colour phases of #. mazillosus are common in Madagascar.

and the Comoros, none have been collected in the Seychelles and

Glorioso Islands; they are likewise absent from New Caledonia and

the Loyalty Islands, while still occurring in the New Hebrides.

Eumenes macrocephala, H. de Saussure, Et. Fam. Vesp., i, 1852,

p. 37 (3).

The following is a translation of the original description :—

_“ Black, ornamented with yellow. |

‘“* Male.—Length: 18 mm.; spread of wing: 32 mm.

“ Female unknown. |

““ Male.—A thickset insect. Head black, thick, so that the eyes

do not entirely cover the sides. Clypeus straightly truncate at the

anterior margin, yellow and slightly silvery. Mandibles, an incom-

plete margin of the orbits, a triangular spot on the front, and a spot

on each side of the mandibles below the head, yellow. Antennae

yellow on the under side, black on the upper side. Thorax black ;

prothorax yellow, with black posterior corners ; between these corners

and the tegulae there is an arcuate ferruginous line. Tegulae, two

spots on the corners of the scutellum, and postscutellum yellow, as

is also a large spot on each side of the metathorax. Head and thorax

granulate, covered with russet pile. Petiole strongly campanulate,

without any spine, black, ending in an irregular, yellow fascia ; its

swollen portion longitudinally furrowed. Second abdominal segment

oval, black, margined with a broad yellow fascia somewhat notched

in the middle, and marked on the sides with two elongate spots that

almost join on the middle line; third segment yellow with a black

base; the succeeding segments black with a rather indistinct, ferru-

ginous marginal line. Under side of the abdomen black, the second

segment ornamented with three yellow spots that almost touch, the

succeeding segments with a broad, longitudinal, yellow band. Legs

yellow ; coxae and basal half of femora black, with a yellow dot on

each coxa. Wings hyaline, slightly ferruginous; a brown tinge in

the radial cell.

“ Relationship and differences.—Very close to H. amedev. It differs

from that species in the clypeus being straightly truncate and not.

rounded off, etc.

“ Inhabits the Cape of Good Hope (Jurine Collection at the Museum

of Geneva).”

A. vy. Schulthess (Societas Entomol., xxv, 1910, p. 24), who examined

the type, states that H. macrocephala cannot be distinguished from

the Palaearctic EL. arbustorum (Panzer). He suggests that the country

of origin given by de Saussure might have been due to an error. I

have, however, received from the South African Museum a male

which agrees perfectly with de Saussure’s description of macrocephala,

and I have little doubt that it represents that species. The specimen

is labelled Potchefstroom, Transvaal (T. Ayres), and there is no reason

to assume that this is due to an error, as the South African Museum

possesses no Palaearctic wasps. A detailed description of this

specimen follows.

Male.—Head seen in front but little broader than high. Clypeus

much longer than wide, elongate hexagonal, but little convex and

slightly depressed before the apex; the anterior, free portion about

as long as the upper, interocular part ; the apical margin a little over

one-third, but less than one-half, the total width of the clypeus,

straightly truncate, with distinct but bluntly rounded edges. Vertex

without fovea. Ocelli placed in a flattened triangle; the posterior

ocelli a little farther apart than from the inner orbits, about. as far

apart as from the hind margin of the vertex ; anterior ocellus larger.

Front much raised and distinctly, though bluntly, carmate between

the antennae. LHyes bare, about one and one-half times as far apart

on the vertex as at the clypeus. Vertex and temples quite well

developed, as in #. arbustorum, margined behind with a continuous,

sharp rim. Mandibles very long and slender, decussate, straight, not

curved at apex, with three superficial notches along the inner margin.

Antennae moderately elongate; the flagellum almost uniformly

thick over its entire length ; antennal sesments—4 to 6 distinctly and

7 slightly longer than broad, 8 square, 9 to 12 very little broader

than long ; terminal hook long, robust and strongly curved, the blunt

apex lying in a deep pit at the under side in the centre of the tenth

antennal segment ; in profile the hook is finger-shaped, being rather

rapidly narrowed beyond the base; but seen from the upper side it

is lengthened spatulate and bluntly ridged in the middle over the

entire dorsal length. Thorax elongate oval, quite convex dorsally,

about one and one-half times as long as high in profile, and one-third

longer than wide seen from above. Pronotum squarely truncate ;

the anterior margin rimmed throughout with a distinct raised line,

which is but little more pronounced on the sides, below the humeral

angles. Humeral angles quite distinct, but blunt. Mesonotum about

as long as wide, with a fine, median, impressed line over its anterior

half. Scutellum slightly convex, very gently sloping posteriorly, with

a distinct, median, longitudinal line almost forming a furrow pos-

teriorly. Postscutellum almost flat, somewhat depressed posteriorly,

entirely within the posterior slope of the thorax, without any trace

of median line. Propodeum moderately developed, seen from above

about as long as the scutellum, quite convex, completely rounded off,

without ridges or projecting angles on the sides, quite deeply grooved

in the middle over its whole length ; just above the base of the abdomen

the sides of the channel are much raised and form a blunt angle, which

is separated by a narrow notch from the valvulae. Mesopleura with-

out carinae or ridges along the epicnemial depressions, which are but

slightly marked for the fore and middle legs. Legs more slender than

in £. arbustorum: the hind tibiae are rather more abruptly widened

in the apical half than in that species, being more slender at the

base ; the tarsi are also thinner, the difference being quite well marked

in the middle and hind tarsi; the basitarsus of the middle legs,

although more slender than in £. arbustorum, has the same characteristic

shape: it forms an elongate prism, with a flattened under surface, the

upper surface divided by a blunt ridge into an anterior bare and a

posterior densely hairy face *; the hairs are short, stiff, and some-

what silky, and form a conspicuous brush; this brush is present in

other Humenes too, but in both arbustorum and macrocephala it is

quite conspicuous on account of the unusual shortening of the basi-

tarsus. Venation of wings of the usual Humenes type, differing but

little from that of EL. arbustorum and E. caffer. First abdominal

segment moderately long, elongate campanulate, more slender than

in L£. arbustorum; nearly as long as the thorax in profile; a little

over three times as long as its greatest width seen from above ; nearly

straight along the ventral line in profile; rather suddenly swollen in

its apical half, which is but little more than twice as thick as the base,

regularly convex and gently sloping toward the apex ; in profile it is

considerably less swollen than in #. arbustorum, though of the same

general shape ; seen from above the basal half forms a slender petiole,

which widens abruptly into the swollen apical half; this swollen

portion is over twice as wide as the basal stalk, fairly parallel-sided,

though not with straight margins, much more elongate than in

E. arbustorum, nearly twice as long as its greatest width, dorsally with

a longitudinal groove, which becomes quite deep before the apex ;

the spiracles form very low but distinct protuberances on the sides

near the base of the swollen part, but they are not visible from above.

Second segment elongate oval and slightly depressed, about equally

convex dorsally and ventrally, about one and one-half times as long

as high in profile and one and one-half times as long as wide seen

from above; basal neck short, but quite distinct, conspicuously

narrower than the apex of the first tergite; apical margin simple,

depressed; sternite flattened at base. Last (seventh) sternite

straightly truncate at apex, with broadly rounded edges, the apical

margin slightly raised in the middle; its surface conspicuously con-

cave, forming a broad, somewhat triangular cavity, which narrows

toward the base of the sternite, where it is more like a channel between

two converging, blunt ridges ; the concave area is finely granulate and

covered with short hairs, which are somewhat longer toward the apex.

* This peculiarity of H. arbustorum is correctly described by F. Morawitz, Horae

Soc. Ent. Rossicae, xxix, 1895, p. 419.

572 Annals of the South African Museum.

Puncturation very dense, but moderately coarse on head and thorax,

somewhat larger on the vertex; clypeus with very few and quite

widely scattered, minute punctures, practically impunctate, dull;

on the temples (behind the eyes) the punctures are very fine and

remote; the median channel of the propodeum shows a series of

transverse striae, especially well marked in the lower half; tegulae

with few, irregular punctures toward the margins, nearly impunctate

in the centre. First abdominal tergite smooth and impunctate in its

basal two-thirds; the apical third with remote, medium-sized

punctures, much smaller than those of the thorax, and fairly uniformly

scattered over the entire width. The remainder of the abdomen

impunctate, except for a few minute punctures on the basal neck

of the second tergite. Head and thorax with moderately long,

greyish pile; the clypeus somewhat silvery; abdomen and legs

almost bare.

Black, with conspicuous and abundant bright yellow markings as

follows: clypeus; mandibles (passing into ferruginous in the apical

half) ; scape of antennae (except for a broad, black streak over the

upper surface) ; front between the antennae; inner orbits from the

clypeus to half-way in the ocular sinus; a broad line along the outer

plate of mesopleura entirely and continuous with a very large spot on

the lower plate; posterior half of tegulae; a broad, transverse band

on the scutellum; postscutellum entirely; propodeum (except for

a wide, median stripe in the longitudinal channel); an elongate,

dorsal spot on each side near the base of the swollen part of first

tergite; two much larger spots at apex of first tergite, narrowly

connected medially and produced anteriorly on the sides; second

tergite, except for a broad black mark in the shape of an inverted T,

the base of which widens over the basal neck, while the arms form a

transverse band about the middle (the yellow covering about the

apical third of the tergite and somewhat angularly notched with

black medially); second sternite (except for the basal black third

and a small black spot on each side shortly before the apex) ; third

to sixth sternites and tergites, except at base; a transverse fascia

over the middle of the seventh tergite; large spots on the fore and

middle coxae; the major part of the fore and middle femora; the

tibiae and much of the tarsi. The basal half of the flagellum and the

hind femora are bright ferruginous-red ; while the upper side of the

fore and middle femora is extensively ferruginous and the apex of

the tibiae and tarsi also shows a ferruginous tinge. Wings sub-

hyaline, somewhat suffused with amber-yellow anteriorly, especially

in the subcostal cell; the radial cell more infuscated and somewhat

purplish.

Length (h.+th.+t. 1+2): 14 mm.

A comparison with males of typical #. arbustorum (Panzer), of the

Pyrenees, France, discloses several differences in structure, some of

which may be pointed out :

(a) The clypeus is much longer than wide and straightly truncate

at the apex. In arbustorum, it is relatively shorter and quite evenly,

arcuately rounded off.

(b) The flagellum is shorter and thicker throughout; its terminal

hook rather narrow and bluntly ridged over the whole length. In

arbustorum, it is more elongate, almost all the antennal segments

(except the eleventh and twelfth) being longer than wide ; the terminal

hook broadly spatulate, with a short dorsal crest (fig. 14, J—J).

more than one-fourth longer than high.

(d) The propodeum is more convex on the sides, the median channel

being much deeper. In arbustorum, the channel is more broadly open

and its sides do not form blunt angles above the valvulae.

(e) The legs are more slender, which is especially conspicuous for

the tarsi and the hind tibiae. In macrocephala, the middle basitarsus

is over twice the length of the second tarsal segment and about

three times as long as wide. In arbustorum, the hind tibiae are

short and thick, gradually widening from base to apex; the middle

basitarsus is about twice the length of the second tarsal segment and

between two and three times as long as wide (fig. 14, H).

(f) The first abdominal segment is shaped quite differently. In

arbustorum, it is distinctly shorter than the thorax; the apical half

much more swollen, nearly three times as thick as the basal stalk in

profile, and seen from above but little longer than wide; it is also

much more densely and coarsely punctured than in the male here

described as macrocephala.

(g) The last sternite in #. arbustorum is more shallowly and uni-

formly depressed.

With regard to coloration the resemblance with HL. arbustorwm var.

ameder, Lepeletier de St. Fargeau, of Algeria, is quite remarkable.

To judge from de Saussure’s description and figure, #. sichelii, de

Saussure (Ht. Fam. Vesp., i, 1852, p. 36, pl. x, fig. 2), of Albania,

is still more like it; in addition, sicheli is said to have the clypeus

straightly truncate at apex, so that 1t might be even more closely

574 Annals of the South African Museum,

allied to macrocephala than arbustorum. Unfortunately I have no

specimens of sechelia for comparison.

Although the structural characters are quite sufficient to regard

arbustorum and macrocephala as specifically distinct—the differences

between some other species of Humenes, such as the Nearctic Z£.

fraternus, Say, EH. verticalis, Say, and EF. globulosus, de Saussure, are

much more obscure—yet there can be little doubt that the two have

been derived from some common ancestor. Nowadays the Palae-

arctic H. arbustorum (with several colour phases) does not extend

southward beyond the Mediterranean subregion, being thus separated

-from E. macrocephala by the entire tropics.

If one relies upon the colour alone, E. macrocephala and E. caffer

might easily be confused, and it is probably for this reason that

macrocephala has been thus far overlooked. The black marking of

the second tergite, however, does not form a complete cross as in

caffer. Structurally the two are not in the least related.

Distinguished by the more sub-parallel shape of the elytra in the 4,

which is much narrower than in Delegorguez, while in the ? the elytra

are much less constricted towards the base and less ampliated towards

the middle; the prothorax is slightly broader in both sexes than in

Delegorguet, and the median longitudinal line much more distinct ;

the costae and sculpture of the intervals of the elytra are much the

same in all the species of the genus, but the scabrose impressions in

the intervals of the costae are single in the anterior part in this 9.

Two examples, a gd anda. The former, the type of the species, is

proportionally smaller than the example I take to be the 2 and much

more parallel-shaped.

Craspedophorus, and also Epicosmus, are posterior to Hudema.

Chaudoir includes in Eudema only one Indian species, whereas Castel-

nau founded the genus for the African and Indian species.

The difference between Craspedophorus sensu Chaud. and Hpicosmus,

also sensu Chaud., seems to consist in a slight variation in the securi-

form shape of the ultimate joint of the palpi.

from the other South African species having a broad thorax by it

being narrower at apex than at the base, more regularly ampliated

laterally and not emarginate towards the basal angle; the surface

is roughly and closely punctate; the sub-parallel elytra are less

densely pubescent than the prothorax, moderately highly costate,

with the striae finely but deeply punctate, and they have each at

about one quarter of the length a yellow band extending from the

4th to the 8th costa, and consisting of three lines united alternately

by two shorter inner ones; in the third posterior part is a similar

patch in which the two alternate lines project more towards the apex

This genus is extremely close to Hudema (Epicosmus), the main

difference according to Chaudoir being in the shape of the ligula, the

paraglossae of which do not project beyond it. The prothorax is

widely arcuate laterally from the neck to the deep hind incision, and

pedunculate at base.

The only African species known is Trichisia rhodesiana Pér.; the

other three species included in the genus are from India, Hong-Kong,

and Hastern Australia.

Gen. CHLAENIUS Bonelli.

Syn: Rhizotrachelus, Vertagus, Ocybatus, Dinodes, Pteroticus.

The additions to this genus are mainly from Southern Rhodesia,

where other species previously described from Nyassaland, British

Kast Africa, and Tanganyika Territory will be doubtless found to

occur. In Hereroland and Ovamboland only a few species have been

recorded. It is doubtful if any new or striking form will be found

here, because the climatic conditions are identical with those of

Bechuanaland and western South Rhodesia. Very few species are

known from Angola, but the insect fauna of the southern part closely

approximates to that on the left bank of the Cunene River.

I have recast the key to the species of the genus Chlaenius, which

I divide into two sections according to the shape of the last joint

of the palpi—z.e. either (1) securiform or broadly securiform, or (2)

cylindrical. These two divisions are split into subsections according

to the shape of the prothorax, which is regularly ampliate, rounded,

and not or very little more narrowed at base than at apex ; regularly

cordate or elongate cordate, the base being much narrower than the

apex; sub-trapezoidal with the base sinuate laterally, or with the

base not, or very little, sinuate laterally.

This arrangement is a very natural one, and helps to separate with-

out much difficulty species which, in spite of similar livery, have really

no affinity. Only in one case is one species (Chlaenius dohrni) widely

separated from its congeners (Chlaenius zanzibaricus, etc.).

In my Descriptive Catalogue I described this species as a variety

of C. bohemani Chaud., but now that I have examined more material

of both sexes, I find that Chaudoir was right in considering it as

a species different from the latter.

The prothorax is broader, the last jomt of the palpi are not as

broadly securiform in either sex; the yellow patch on the elytra is

much less ovate and extends from the 3rd to the 8th interval, and

is longer on the 5th than on the others. The three basal joints of

antennae are red instead of the basal one only, as in C. bohemani.

same, the very closely aciculate the intervals are plane (3) instead

In this species the yellow markings are very variable. Thus in an

example from 8. Rhodesia (Salisbury) (Q), and in another from Durban

(3), a somewhat larger specimen, the discoidal patches are altogether

absent. In an example (2) from Delagoa (Rikatla) this patch, and

also the apical one, are so faint as to escape detection, while in another

example ($) from the same locality there are no traces whatever of

yellow markings. It is this variety which I considered at first to

be identical with C. notidiceps Dej., which is smaller, less ampliated

behind in the 9, and has not been recorded hitherto but from the

western part of the Cape of Good Hope.

but impunctate in the centre ; prothorax gradually ampliate laterally

but only very slightly sinuate towards the base, where it is also only

very slightly wider than at the apex, the posterior angle in a line

with the 5th stria of elytra, length nearly equal to the width, closely

and deeply punctured and clothed like the elytra with a dense, flavous

pubescence; elytra parallel ($), narrowly striate, the intervals plane

but slightly convex in the anterior part, and very closely and some-

what roughly punctate; anterior tibiae ($) with a very small basal

tooth underneath, underside with the normal sculpture.

Length, 12 mm.; width, 44 mm.

Chlaenius levicollis sp. n.

Head and prothorax red, shining, elytra black with a faint cyaneous

tinge, and the outer marginal interval dark green; antennae, palpi,

and legs red; head non-aciculate, prothorax ampliate rounded

laterally, slightly narrowed towards the base, but broad, not sinuate,

and as broad as long, with the basal angles in a line with the 6th stria,

disk without any puncture ; elytra elongate, oblong, narrowly punctate

striate, the intervals highly costate.

Chlaenvus controversus sp. n.

In shape, size, and colour it is like C. bepustulatus Boh., but it

differs in the following characters: the punctures on the prothorax

are deeper, and equally spread on the disk, while in C. bipustulatus the

median part is almost impunctate from the interior part to the fore

point of the discoidal sulci; the intervals on the elytra are quite

plane from about a fifth of the length to the apex (¢), whereas in

bipustulatus (2) they are raised, slightly convex, and more distinctly

shagreened than in C. controversus, the posterior yellow patch instead

of being sub-quadrate extends from the 3rd stria to the 8th, and is

continued there and merges into an apical marginal moderately broad

band, thus forming a conspicuous crescent-shaped band somewhat

similar to that of C. conformis, which is, however, plainly distinct

from C. controversus.

Length, 14 mm. ; width, 6 mm.

Locality.—S. Rhodesia (Macloutsi River) ; Mozambique (Beira).

taken for C. conformis, ranging from Senegal to Natal.

Gen. UMTALIUS gen. n.

I propose this genus for a singular form of Chlaenud, which I

described as a Chlaenwus (C. epigraphidus), not only on account of its

singular livery, which greatly resembles that of the species of the

Panagaeid genus Hpigraphus, but also because of the shape of the

labial palpi, which are very broadly bell-shaped, and not obliquely

truncate, while the maxillary are cylindrical. Although the two

examples I examined are females, it will probably be found that the

three basal joints of the tarsi are not dilated in the male.

Parachlaenius pretorvanus n. sp.

Chestnut brown, with the tarsi somewhat darker; head finely

frontal part is smooth ; prothorax as broad as long, slightly arcuate

outwardly from the projecting apex to about the middle, and inwardly

thence to the sharp basal angle; it bears a few very scattered punctures,

the outer margin is sharply reflexed, the basal impressions of the disk

are very plane, and the median longitudinal suleus plane, elytra

paralleled with the humeral angles rounded, hardly convex except in

the posterior part, finely striate punctate with the intervals plane,

very closely aciculate, and densely pubescent, the pubescence erect ;

underside closely punctate and pubescent ; legs also pubescent.

This species differs from P. sengularzs, which is a much larger species,

by the finer and more closely set punctures in the intervals of the

Systolocranius ampliolatus sp. n.

Black, shiny above on the underside; the palpi and antennae piceous,

joints 4-11 fulvo pubescent; head and prothorax impunctate and

similar in shape to that of S. validus; the elytra instead of being

parallel as in the above-mentioned species are gradually ampliated

laterally from near the base to the third part of the length, where

they are one-fifth wider than at the base; they are finely punctate

striate, with the Ist to the 3rd intervals nearly plane, and the others

gradually tectiform, especially in the posterior part; there is only

one distinct puncture on the 3rd interval half-way between the middle

and apex, and not in a line with the puncture on the opposite side ;

underside sub-iridescent.

Closely allied to S. goryz Laf. from Senegambia, and recorded also

from Uganda, Guinea, and erroneously from the Cape. The lateral

attenuation of the prothorax begins from the median part, and is

therefore more noticeable than in S. gory; the lateral post-humeral

sinuation of the elytra is very distinct, whereas in S. gory there is

none, and in the latter the striae are more distinctly punctate and

the intervals more convex or more sharply costate, even in the female.

Moreover, there are two punctures on the 3rd interval in S. goryz, and

only a posterior one in S. ampliolatus. In general appearance this

species greatly resembles Chlaenius cham, but can be at once distin-

guished by the absence of the puncture on the outer angle of the

base of the prothorax.

Differs mainly from O. natalensis by its much broader size, it being

twice the width of the other ; the prothorax is therefore proportionally

less attenuate in the anterior part, and more distinctly wider at apex

than the base, and the basal impressions are not so clearly line-like ;

the elytra have the same shape, and, being wider, the punctation of

the striae is more conspicuous, and the six striae on each side are

equally complete ; the underside and legs are denser black in all my

The insects included in this genus have a superficial resemblance

to that of some species of Abacetus of the tribe Feronium, and

likewise they have two supra-orbital setae, thus differing from the

Chlaenint and Oodini, but they are, however, separated by several

distinct characters, such as the position of the 2nd antennal joint,

which is set in the axis of the basal joint instead of the outer part,

the shape of the joints of the anterior tarsi of the male, etc.

The South African species are very closely allied to each other, and

only distinguishable by comparison.

Melanodes proximus sp. n.

Shiny black with a slight iridescence, antennae and legs dark

piceous ; easily recognised from the other South African species by the

size of the pronotum, which is broader than long, distinctly attenuate,

rounded in the first anterior part, but is very much less so from below

the centre to the sharp basal angle ; the lateral fold above the sulcus

is slightly broader behind than in the other species, somewhat in the

manner of some species of Abacetus ; the elytra are wider in proportion

to the width of the pronotum, and have the usual structure of the

other species of the genus. Underside iridescent ; pectus closely and

somewhat deeply punctate. One female.

TrinE DITOMINI.

Antennae inserted under a frontal ridge; frons with one supra-

orbital seta; pronotum with one seta anteriorly, or none, cordiform

or elongate cordate; body pedunculate ; elytra depressed, occasion-

ally pubescent, normally rounded at apex; legs moderately robust ;

anterior tibiae deeply incised, the spurs very distant from each other ;

tarsi simple in both sexes.

This tribe has never been considered to be homogeneous. Thus

Coscinia, which I removed from it, has two supra-orbital setae, and

Melaenus, one of the three genera I include, Bascanus, and its close

ally Bascanidius, differ in facies from Melaenus, and while they both

have only one supra-orbital seta, there seems to be none on the pro-

as well as the penultimate ones, for their great length, are fusiform

outwardly only, the inner part being very obliquely truncate in both

sexes for about half their length, but not quite securiform ; there is

one supra-orbital seta set at the back of the eye, and I cannot detect

any on the pronotal outer margin.

BASCANIDIUS gen. n.

This genus differs from Bascanus in the shorter mandibles, the

very short and broadly incised labrum, the less slender pronotum

and the more parallel elytra. The last palpal joints are a little more

tobust and a little more obliquely truncate inwardly (3).

Trise LICININI.

Descr. Cat., p. 525.

Characteristic of the Licinidae, as represented in South Africa, are

the brevity of the clypeus, the long, deeply cleft labrum, and the shape

of the mandibles, which are usually blunt at apex on one side and

sometimes on both, when they are deeply scooped inwardly; the

maxillae are armed with sharp robust spines. There are two supra-

orbital setae—a lateral nearly median one on the pronotum, and a

puncture, occasionally very indistinct, at the posterior angle of the

latter; there is a puncture on the 3rd interval of elytra; in the

male the 3 first joints of the anterior tarsi are spongy underneath,

the 2 basal joints being triangularly dilated, but the 3rd is occa-

sionally slightly transverse. The palaearctic genus Licinus has not

to my knowledge been met with in the Ethiopian Region.

rounded laterally, but slightly more towards the median part than in

A. forcipatus, and although this difference is slight, yet the pronotum

is less obliquely attenuate laterally towards the posterior angle, and

shiny ; the elytra are likewise slightly broader, not striate, the suture

is carinulate, and at a short distance from it is a highly carinate dorsal

ridge, beginning at a distance from the base and reaching to about the

same distance from the apex as it does from the base, and another

and very much shorter in the median part.

disappears beyond it, and there are traces of a very faint striate on

the general facies is short, quite ovate; the fore tibiae are pluri-

spinose outwardly, and slightly emarginate after the second outer

spine; the mandibles are flat; the short head is deeply set in the

pronotum, which is short and very transverse, and plainly arcuate on

each side of the base, and having a very weak median longitudinal

impressed line; the elytra are more ovate than in Anaulacus, the

suture is tectiform, the striae are very indistinct, but some seriate

head smooth, impunctate, the first setigerous orbital puncture very

conspicuous ; pronotum quite smooth, shiny, with the median line

distinct ; the outer margin narrowly brownish red ; elytra void, fitting

exactly against the pronotum, but deeply impressed on each side of

the scutellum, moderately convex for two-thirds of the length, and

with the suture tectiform for nearly four-fifths of the length ; indis-

tinctly impunctate striate, but with the stria above the marginal fold

This species was first captured at Rouen in France. Rafiray found

it at Pemba Island (Zanzibar). The two examples I examined were

TrinE DISPHAERICINI.

The two genera Spanus and Disphaericus should be placed in a sub-

family of their own, not in the Stomini, in which they were first in-

cluded and with which they agree only relatively, nor in the Pana-

gaenini, where they are placed by Kolbe. With some members of the

first sub-family the only thing they appear to have in common is a

pedunculate thorax. The elongation of the head recalls that of some

Panagaevn, but the difference in the shape of the mandibles, distinctly

toothed in the median part, the clavate fore femora, the fore tibiae

without outer terminal spur or row of spines, and the inner spur very

short and incurved, the series and deposition of deep puncture on the

supra-epipleural interval, the short joints of the fore and intermediate

tarsi, as well as the glabrous body, approximate them to the Ptero-

stichimt rather than to the Panagaewn. There are two supra-orbital

setae.

The description I gave (loc. cit.) was made from a partly mutilated

specimen. The species differs from both S. ebeninus and S. concinnus

in having a supra-lateral impunctate line—like stria obliterated in the

fourth anterior part, the space between this line and the supra-epi-

pleural stria slightly tectiform and overlapping the latter; the shape

of the prothorax is less elongated than in S. concinnus and less

ampliated than in S. ebeninus; the juxta-sutural stria reaches from

base to apex, and the punctures are deeper than in any of the two

above-named species ; the apical puncture is conspicuously large.

Cape (no exact locality).

Gen. SPANUS Westw.

Descr. Cat., p. 537.

Spanus concinnus sp. N.

Smooth, very shiny; antennae, palpi, and legs rufescent ; closely

allied to S. ebenonus Chaud. ; differs mostly in the shape of the pro-

notum, which is one-third longer than broad, and elongate with the

sides straight, whereas in S. ebenanus it is well ampliate, being nearly as

broad as long, and slightly wider across the base than across the apex ;

the shape and sculpture of the elytra are the same, but the juxta-

sutural punctate stria reaches only to the rounding of the posterior

declivity instead of the apex, and there is a conspicuous puncture

close to, but of course outside, the supra-epipleural series of

punctures, which are, however, deeper in S. ebeninus, in which species

the puncture is less distinctly outside the series. Underside smooth,

the setigerous punctures of the abdominal series deep ; intermediate

tarsi nearly as much dilated as the anterior in the male, all densely

spongy underneath, hind ones densely ciliate.

Length, 6 mm. ; width, 2 mm.

Locality.—Cape (Fort Beaufort).

TrisE PTEROSTICHINI.

Deser. Cat., p. 544.

The South African species are included into three groups: Drimo-

stomides, Abacetides, Pterostichides. The first two groups are homo-

geneous, the third is not, the facies of the species being often strongly

dissimilar ; but in spite of differences in detail there is little doubt that

they all belong to one and the same group, which I have, however,

divided into two sections. The first includes eight genera of a pure

African type, and one the facies of which has some resemblance to

palaearctic forms. It is in the second, however, that this resemblance

is carried to a greater degree of similarity. In my Descriptive Cata-

logue I included a number of species in the genus Pterostichus (olim

Feronia), being, I think, justified by finding in the South African

species many characters which are characteristic of the palaearctic

species. Tschitschérine has, however, proposed a new division of the

South African species, founding some new genera and several sub-

genera. Some of his new genera I have now adopted; the others

I have raised to genera, and I have added two, admitting, however,

that the characters ascribed to most of them are not always of

important generic value; but this arrangement makes identification

easier.

Moreover, there is a very important point in adopting this new

division. So far as we know, none of the forms included in that

Section IT have yet been met with outside South Africa, the Transvaal

being the most northern limit. One species described by Fairmaire

as an Omaseus, a genus well represented in the Palaearctic Region,

O. relexicollos, from Usagara, Central Africa, is pronounced by Tschit-

schérine to be an Abacetus, a genus extremely rich in species in

Africa. This absence of intermediate forms is very striking. If it

proves to be true, it makes it difficult to explain satisfactorily the

retention of general facies and something more in localities so very

remote, except on the hypothesis of convergence to a type or facies

moulded by environment or habit.

The South African species inhabit both plain and mountain. Two

species, C. chalcostoma and C. captatriz, are found in the same locality,

the first in the plain, the other on the mountain slopes from 800 to

1000 feet. Mosuta alticola has been met at an altitude of 8500 feet ;

it is therefore possible that alpine Central African forms of the same

type may still be met, thus bridging the gap.

Descr. Cat., p. 545.

In my description of the genus I omitted to mention the peculiar

insertion of the second antennal joint, which is set on the outer axis

instead of the centre of the first, and which is thus a peculiar character-

istic of the group. A second omission is the presence of a setigerous

puncture on the 38rd interval of the elytra, and the absence of a

prescutellary stria or striole. The puncture on the 3rd interval of

elytra is not situated always slightly past the median part; it

may be slightly ante-median (anopinus, evulsus, etc.) or long past the

middle (obtusus); only in one case (shilouvanus) is it completely

absent. I have seen one example only of this species, but it is not

always distinct in certain examples of the same species.

The genus is very poorly represented in the western part of the

Union, where rains are more occasional than in the eastern part,

which is rich in species, and examples are numerous.

A calligraphic error, p. 545 of the Descriptive Catalogue, puts

‘“ Martaban’”’ in South America. The error is of course obvious. The

genus has no representative in America, and it is not certain that true

Abacetus occur in Australia.

Abacetus congruens sp. n.

Allied to the preceding species, but more slender ; the prothorax

is also greatly ampliated in the centre, but the posterior part from

slightly past the middle is very distinctly attenuate, thence towards

the base, and has thus a more broadly cordiform appearance, although

the supra-basal sinuation is not much marked ; the elytra are narrower

and therefore more parallel than in A. optimus; the antennae are

fuscous or even black, except the first joint, which is red, and the

legs are either black or dark piceous, and the elytra are deep black

with occasionally a faint iridescent sheen.

and approximates that of A. chalceus, and the shape of the pronotum

is as in the last-named species—that is to say, the basal angle is

rounded and not aculeate as in A. menutus ; the base has no punctures.

From A. chalceus it differs in the less ampliate pronotum and the

thickened ; the prothorax is ampliate rounded laterally for two-

thirds of the length, thence gradually narrowed towards the basal

angle, but not sinuate, the base being slightly wider than the apex,

and deeply punctate at the centre; the elytra are of an oblong shape,

but with hardly any sloping at the humeral part; the intervals are

plainly convex (9).

Abacetus zambesianus sp. n.

Greenish on the upper side with a chalceous tinge; the first and

second antennal joints are red, the second and third, however, being

somewhat fuscous ; the remainder are deeply infuscate ; the prothorax

is plainly cordate, and as broad as long, the base is deeply and somewhat

closely punctate, the punctures being deep; the oblong elytra are

somewhat longer in proportion than the other species of this group,

striate with the intervals plane; femora fuscous, tibiae and tarsi

slight flavescent.

The elongate form of this species approximates somewhat that of

A. agilis Pér., which, however, belongs to another and well-defined

Dark blue, but sometimes light bronze on the upper side; the legs

sub-piceous red ; the prothorax is broadly cordate, strongly narrowed

at the base, which is strongly punctate, but sometimes sparingly so ;

the intervals of the elytra are sub-tectiform or moderately “plane,

according to the sex.

following fuscous, and the others pale flavescent ; the prothorax is

convex, globose, but narrowly attenuate towards the base, sprinkled

with coarse punctures bearing each a long hair; the base is roughly

punctate, the elytra are twice as broad at the shoulders as the narrow

It would appear that I have mixed Cyrtomoscelis natalensis Chaud.

with Argutor trivialis Boh. JI do not remember having seen the

former, whereas I have compared my specimens with authenticated

examples of the latter, which I now place in a new genus which

differs from Cyrtomoscelis in having the outer margin of the anterior

tibiae distinctly pluri-spinose and the hind tarsal joint grooved,

whereas in Cyrtomoscelis the fore tibiae. arc spineless and the hind

tibiae and tarsi are not grooved.

Cyrtomoscelis natalensis Chaud.

Bull. Mosc., 1873, p. 63.

My description of C. triviales applies to this species. It was, in fact,

made from an example of Cyrtomoscelis ; the pronotum is much more

parallel than in Berea caffra, owing to it being less attenuate and

hardly rounded in the anterior lateral part; the longitudinal central

line is so faint as to be difficult of detection.

In general appearance it closely resembles B. caffra, but is at once

differentiated by the absence of spines on the upper side of the fore

and hind tibiae ; the latter are also not grooved, nor is the basal joint

of the hind tarsi.

To my description may be added the following: Anterior tibiae

with strong spines outwardly, intermediate numerously ; posterior

sparsely spinose, the four upper spines in the latter set on a slightly

dentate projection, forming on the edge of the slightly arcuate tibia

a sort of sinuation; the hind tibiae are grooved inwardly, and the

basal joint of the hind tarsi is also grooved.

Berea caffer sp. n.

Piceous, with the elytra darker and slightly iridescent; more

elongate than B. trwials and less oblong ; the sculpture is identical,

but the pronotum being more elongate is nearly as long as broad,

is attenuate forward laterally for a shorter distance, and thus appears

more parallel; the median longitudinal impressed line is sometimes

difficult to detect ; the elytra are also more elongate and narrower in

proportion than in C. trivialis ; the rest as in the former.

Length, 8 mm.; width, 34 mm.

Locality.—Cape (Transkei, Kentani).

INKOSA gen. n.

The sculpture of the head is very different from that of Berea ; the

frontal sulci are very deep and broad, and edged laterally by a highly

raised border; the lateral puncture of the labrum is very deep and

broad ; the head, owing to shortness of neck, is deeply set in the

pronotum, which is much broader in the anterior part in spite of

the prominence of the eyes; the pronotum has a distinctly sulcate

border, and is as broad at the base as the elytra; the legs are as

in Berea.

Inkosa latiuscula sp. n.

Black, shiny, not iridescent; palpi and antennae rufescent ; legs

reddish brown. Head with the frontal impressions broad, deep, and

edged with a high border above the eyes; lateral puncture of the

labrum fossate; prothorax twice as broad as the head at apex,

attenuate rounded laterally to about the median part, where it is

twice as broad as long, straight thence to the base, where it is as

wide or nearly so as the shoulders ; outer margin sharp, reflexed, no

scutellary striole; elytra with the intervals only moderately convex

on the disk, the convexity more pronounced laterally, especially in

the §; the striae apparently impunctate, underside smooth, the three

abdominal segments with a series of deep punctures along the anterior

border ; anterior and intermediate tibiae spinose outwardly, posterior

a little arcuate, grooved, and with a few spines. Hasily recognised by

its ampliate facies.

Gen. CELIOSCHESIS Tschits.

Hor. Soc. Ent. Ross., vol. xxxu, 1898, p. 93.

Head small, eyes convex and projecting ; frontal sulci well defined ;

outer border of the intermediary (especially) and posterior tibiae set

with more numerous spinules; first joint of the intermediate and

hind tarsi much elongated, yet not longer than the three following ;

first joint of the anterior tarsi (dilated) almost triangular, slightly

longer than the second; paraglossae projecting a little beyond the

apex of the ligula. Elytra with or without red spot; third interval

with a small poriferous puncture.

The characteristics of this genus are given by Tschitscherus as

approximating those of Cyrtomoscelis, which was unknown to him

except from description. He includes in it Feronia trialis (Berea)

- Boh., which, it can be safely assumed, was also unknown to him, and

which has no puncture on the 3rd interval of elytra. It is therefore

a matter of doubt if the species I refer to the genus is correctly placed,

yet I believe it to be allied to, if not identical with, the type of the

genus—i.e. C. distagma Tschits. The species of this genus are said

by him to be met with in the eastern part of South Africa and in

Madagascar.

Celioschesis longicorns Per.

Suppl. Deser. Cat. (Drimostoma), p. 363.

As I stated in my description, the general facies of this species

approximates it to a certain extent to Stomonazus amarordes, but it

does not belong to the same group of the Pterostichini, as well instanced

by the length of the antennae, etc. ; the general facies of the only

species known to me approximates a little that of Imkosa latvuscula,

but is not so massively ampliate, and the 3rd interval bears a dis-

tinct deep poriferous puncture set a little past the median part. In

comparison with C. distagma Tschits. it seems to be a little more

parallel.

narrowed in front but very little behind, widest in the middle, angles

obtuse, sides regularly arcuate, but the arcuation more pronounced

at the first third of the length, slightly convex in the centre; the

median impressed line reaches neither base nor apex, the space

separating the sides from the lateral fold is slightly depressed ; the

hind piliferous pore is situated not in the groove, as is usually the

case, but on the external fold at the very summit of the angle. Hlytra

not quite 1-5 time as long as wide, 2-5 as long, and 1-16 times as

broad as the pronotum, and having its greatest width at about the

median part; the base is not wider than that of the pronotum and

fits against it, the first fifth of the length of the sides is slightly arcuate

towards the shoulders, thence nearly parallel to slightly past the

middle, and from there moderately arcuate; the shoulders are not

rounded, although slightly obtuse ; the striae are strongly marked,

and become deeper still towards the apex; the intervals are moder-

ately convex; prosternum entirely smooth; episterna slightly

punctuate; sides of abdominal segments punctate and _ slightly

rugolose.”

of disemblance being the shape of the pronotum, which, instead of

being slanting laterally in a straight line from the median part to

the basal angle, is plainly sinuate there with the basal angle thus

made more distinctly acuminate; the striae are seemingly slightly

less plainly punctate, but the intervals are alike.

Cophosomorpha elrzabethae sp. n.

Black, shiny, antennae, palpi, and legs piceous rufescent ; head of

head, narrower at the base than at the apex by one-fourth, with the

sides arcuate, the arcuation more strongly defined in the third posterior

This species is easily recognised by the strong lateral sinuation

of the posterior part of the elytra, the apical part of which is almost

dentate, the posterior border almost truncate, and the suture bluntiy

dentate on each side.

Some errors seem to have crept into the habitat I gave for this species.

I have recorded it only from Port Elizabeth, Graham’s Town, and

now Cape Town. The localities Somerset Hast and Seymour do not

apply to this species, and Port St. John and Durban are erroneous.

Cophosomorpha blacsea sp. un.

Closely allied to C. anceyi, but the pronotum is laterally more

ampliate owing to it being less attenuate the median part to the outer

angle, which is also more angular, and the basal depression is deeper

and broader; the elytra are slightly less parallel from the base to

past two-thirds of the length ; the intervals are a little more tectiform,

and on the third there are two punctures, the first at about one-third

of the length, and the other at a slightly shorter distance from the

first than the first is from the base. . The rest asin C. anceyi. In the

Black, shiny, with the antennae and the abdomen piceous red. The

general facies is that of C. capicola and C. lugubrina, especially the

latter, but the disposition of the punctures on the 3rd interval is

different, the first being slightly ante-median and the second situated

near to the apex ; the intervals of the elytra are very slightly convex,

the 5th not much more so at the base than the others (2); the last

segment of the abdomen has a distinct transverse basal groove

obliterated in the centre.

Cophosomorpha laetans sp. n.

Black, shiny, elytra slightly iridescent. Antennae, tibiae, and legs

but as broad at the base as at the apex; the posterior angles slightly

intervals moderately tectiform, the third with two punctures, the

first at about a third of the length, the second at an equal distance

from the apex as the first one is from the base; underside smooth,

the two last abdominal segments with a distinct transverse sulcus

running along the basal part of the segment.

This species is not unlike C. natalensis, and the shape of the pro-

notum is nearly identical ; the elytra are less convex and the intervals

less tectiform, and the two punctures on the 3rd interval, which are

entirely absent in C. natalensis, are very distinct, and their disposition

about two-thirds of the length, and normally attenuate thence; the

scutellary striole is very distinct, the intervals of the elytra are sub

tectiform, with the 7th strongly carinate in the anterior median part,

and on the 3rd there is a puncture situated at two-thirds of the length,

and another at a very short distance from the apex in a line with the

apex of the 4th interval; underside and legs very shiny.

Gen. MosuTa gen. n.

The only species included in the genus is differentiated from the

three preceding by the narrower and more linear shape ; the pronotum

is gradually attenuated from apex to base, where it is only half the

width of the apex, without sinuation or reflexed margin in the posterior

part ; the number and disposition of the punctures on the 3rd interval

differ from that of the other South African species of Pterostichinc.

The last three abdominal segments have a transverse basal groove.

Not having any longer the type of this species, which I described

the genus.

Gen. TERATOTARSA Tschits.

Descr. Cat., p. 566.

In this genus the three basal joints of the anterior tibiae of the

male are exactly like those of the female—that is to say, not dilated

or spongy underneath. The sex difference consists in the presence

of two setigerous punctures near the border of the last abdominal

segments in the female and of one in the male, as in all the Carabid

species. The projection of the metasternum is plurisetose, whereas

it is glabrous in the other genera.

The two species included in this genus have so far been met on

the slopes of peaks or mountain ranges only.

Teratotarsa minor sp. nN.

Black, with the elytra semi-opaque, the antennal joints slightly

rufescent and the palpi piceous; head of the normal shape and

structure ; pronotum a little attenuate laterally from the slightly

ampliate median part towards the base, sub-sinuate above it, the

base a little narrower than the apex, with the angles very sharp ;

disk with only a narrow impression along the basal angle, which is

thus not much recurved ; the median line and basal discoidal impres-

sions are normal, and the fold of the outer margin is distinctly

crenulate; scutellary striole distinct; elytra elongate ovate with

the shoulders acute, somewhat plane for two-thirds of the length,

with the intervals hardly convex in the median discoidal part, the

convexity being more apparent laterally and in the posterior part ;

the 6th interval is carinate in the anterior part, but much less so

than in S. severini or S. rugipennis ; there is a deep puncture in the

BARNARDIA gen. n.

Barnardia superciliaris n. sp.

Black, with the elytra nearly opaque, antennal joints somewhat

rufescent, palpi piceous red; head smooth, clypeus very slightly

plicate longitudinally ; pronotum broader than long, and slightly

wider at the base than at the apex ; sides very moderately ampliate

rounded from the base to about two-thirds of the length, a little

sinuate thence to the basal angle, which is thus projecting and very

sharp ; disk nearly plane, but the base is broadly and equally depressed

from side to side, the depression ascending a little laterally ; the supra-

lateral sulcus is merged in the depression and the outer marginal

border is faintly serrulate; scutellary striole distinct, punctulate ;

elytra as wide at the shoulders as the median part of the pronotum,

conspicuously punctate striate with the intervals plane on the dorsal

part, 7th and 8th sharply tectiform, the former not conspicuously

carinate in the anterior part ; the series of larger punctures on the &th

are Closely set and equi-distant ; there is a 9th punctate stria, and even

a distinct but vaguely punctate 10th stria, beginning at about the

median part and reaching the apex; no puncture on the 3rd interval

in the g, but a distinct one in the 9; legs normal; underside finely but

irregularly plicate. I have seen one ¢ and four 99. Distinguished

from the other species by the presence of a conspicuous thick frontal

ridge extending from the clypeal suture to beyond the eye, and

bordered by a deep, narrow frontal sulcus slightly sinuose behind and

reaching the second punctigerous puncture; the punctation of the

elytra differs also greatly from that of all the South African species

of the group.

Gen. OamMoPrHoRA Tschits.

Hor. Soc. Ent. Ross., vol. xxxu, p. 20.

The facies of the species included in this genus is different from

that of the others belonging to the group, in being more slender, owing

to the pronotum being more distinctly rounded laterally, and especially

towards the base, although not sinuate there, and the elytra having

a more depressed appearance ; the frontal sulci are longer and deeper,

but the border formed thereby is not so much raised nor is it pro-

longed so far over the eyes as in Barnardia ; the metasternal episterna

are longer than broad on the anterior border, and in the only species

of this genus the last three abdominal segments are grooved trans-

versely at the base.

d piceous brown, upper part of body slightly bronzy, with a silky

lustre ; legs reddish brown; antennae reddish, with joints 2-6 more

or less spotted with brown; palpi brownish, with the end of the last

lighter.

This species is extremely closely allied to C. lenis Germ., but dis-

tinct. It differs in addition to the much more obscure coloration of

the palpi, antennae, and legs, and the less bright bronze sheen of the

surface of the body, firstly by the shape of the pronotum, which is

distinctly wider, also of about equal length (1:2 as broad as long),

with the anterior angles projecting although very feebly, whereas in

C. lenis these angles are not projecting; the elytra are also wider,

broader at the shoulders, narrower behind, and less elongate in

proportion to the length (1°6 as long as wide), instead of 1°75 as in

C. lenis. The head is a little less wide between the eyes, and slightly

plicate in the only example I have, but this may prove to be an

individual character.

instead of being more or less green tessellated with yellow elongate

Pale testaceous, with the antennae and palpi light flavescent ;

head smooth, eyes bulging; prothorax transverse, a little attenuate

and slightly sinuate from the median part towards the base, with

the angle sharp, smooth, with a distinct longitudinal impression, the

basal one deep and smooth ; elytra oblong, and having eight punctate

striae with the first four intervals, the 3rd especially, somewhat

tectiform ; the Ist stria reaches from the base to the apical sinus;

the others begin equally at the top of the basal depression, and reach

the top of the posterior declivity ; the 6th and 7th are continued a

little further as a series of deep punctures; the two dorsal punctures

Tachys invictus sp. n.

Metallic green, shiny; the five basal antennal joints, palpi, and

legs flavescent ; head normal, sulci short; pronotum broad, wider

than long, attenuate rounded laterally in the anterior part, very

little behind and hardly sinuate above the sharp, slightly projecting

outer angle; elytra oblong, a little wider than the base of the pro-

notum, shoulders somewhat rounded and having each five discoidal

somewhat deep striae, the juxta-sutural of which alone is entire; two

and three begin at the base, four and five at some distance from it,

and all four stop short of the declivity, the second being, however,

more prolonged ; hind sinus very distinct ; each elytron has a yellow

elongate supra-humeral band extending from the outer margin to the

fifth discoidal stria, and reaching from near the base to about the

median part of the length, and a broader one beginning along the

outer margin at about the second third of the length, and extending

on the discoidal part as far as the apex of the striae, and reaching

posteriorly the suture below the second discoidal stria.

Allied to Tachys crassvusculus Boh., and of the same build. The

pronotum is a little longer, there are five discoidal striae instead of

six, and the yellow markings of the elytra are very distinct. Occa-

sionally a faint reddish-yellow patch in the posterior part of the

elytra 1s discernible in T. crassvusculus.

Length, 34 mm. ; width, 14 mm.

Locality.—Natal (Isipingo).

Descriptions of New Species of Carabidae (Coleoptera). 651

Tachys umtalensis sp. n.

Not unlike 7. precarius in general appearance and likewise wholly

testaceous, but there are five discoidal and deeper striae on each side

of the elytra instead of six. On this account it approximates 7. caffer,

but the antennae are wholly flavescent instead of being infuscate ;

the first discoidal stria is deeper, second and third shorter; the size

is about one-third less than T. caffer.

Tachys khownus sp. n.

Black, shiny, antennae long, joints elongate, black with the first

two flavescent ; palpi black; prothorax broadly cordate, distinctly

sinuate above the base, the angle of which is sharp and smooth,

longitudinal transverse basal impressions normal ; elytra oblong, and

having in the posterior part a transverse flavous patch ; each elytron

has three deep, smooth striae, the first one entire, the second begins

at some distance from the basal impression and reaches the declivous

part opposite the hind margin of the apical patch, the third begins at

the first puncture and is continued beyond the second; the eighth

stria 18 entire and very deep, especially near the shoulders.

Length, 24 mm. ; width, 12 mm.

Locality.—Cape (Clanwilliam).

Tachys shiluwanus sp. un.

Black, iridescent; antennae and legs infuscate. Very closely

allied to T. faustus and easily mistaken for this species, but the

iridescence is stronger, the depression along the suture is very marked,

and the second and third striae, which are not so deep as in 7. faustus,

reach the rounding of the hind declivity.

Length, 2+ mm.; width, 12 mm.

Locality.—Transvaal (Pietersburg, Shilouvane).

Tachys moestus sp. n.

Red, with a broad fuscous band on the elytra occupying about one-

third of the area and extending from side to side; elongate-oblong,

antennae, legs, and palpi flavescent ; head normal; pronotum trans-

verse, slightly attenuate sinuate laterally towards the base but not

cordiform ; elytra deeply impressed at the base and bearing each

two discoidal deep striae, the first of which is entire, but the second

begins at one-fifth of the length and reaches slightly further than the

top of the declivity. More parallel than 7. «mtans, the livery of

_ which it approximates ; it is easily distinguished by its much smaller

size, and by the pronotum being broader and less attenuate laterally

towards the base.

Length, 2 mm.; width, 2 mm.

Locality.—Transvaal (Kaapmuiden).

Tachys exiguus Boh.

Deser. Cat., p. 598.

Locality.—Cape (Cape Town, Beaufort West, Clanwilliam).

Tachys agatinus sp. 0.

Black, very shiny, antennae and legs deep black, somewhat robust.

Allied to T. exiguus, which it closely resembles, but is distinguished

by the deep black antennae and legs; the pubescence on the joints

of the former is long and greyish; the shape of the pronotum and

elytra is alike, and the latter has also two discoidal striae, but in

T. agatinus the second stria is shorter than in T. exiguus, beginning

only slightly above the first discoidal puncture and reaching only the

top of the hind declivity.

Length, 2 mm.

Tachys sebakwensis sp. n.

Black, shiny, antennae fuscous with the five apical joints whitish,

legs flavescent with the tibiae slightly lighter ; head of normal shape ;

pronotum regularly ampliate rounded, but slightly angular in the

middle and a little narrower across the base than at the apex ; elytra

oblong, with the base nearly straight and the humeral angles sharp,

but not projecting ; the juxta-sutural stria is deep and smooth, and

so is the posterior sinus; the eighth stria is equally deep.

This species is easily recognised from the other two South African

species in which the apical joints of the elytra are whitish—ie. T.

humeralis and T. optumus—in the greater thickness of the antennal

joints, the five joints of which, instead of six, are white, in the much

more ampliated pronotum, the less ovate elytra, the not acuminate

humeral angles, and the more robust facies.

Length, 3 mm.; width, 14 mm.

Locality.—S. Rhodesia (Sebakwe).

Tachys dives sp. n.

Piceous black, shiny, antennae and legs flavous ; head of the normal

shape, with the eyes very bulging; antennae pale flavescent with

the basal joimt darker; pronotum broadly ampliate, sub-orbicular,

one-fourth broader than long, not sinuate towards the base, which

is equal in width to the apex; elytra slightly more than twice the

width of the pronotum at its widest part, oblong, with the shoulders

slightly sloping but with the angles distinct ; the juxta-sutural stria

is smooth and reaches from a distance from the base to the apex ;

the posterior sinus is strongly marked, and so is the eighth stria ; on

each side are two very distinct yellow patches, the anterior a little

larger and more quadrate than the posterior one, which is rounded

but a little transverse ; the fore tibiae are of the normal shape, but

somewhat ampliate above the supra-apical spinose angle.

The ampliate shape of the pronotum and elytra in proportion to —

its length is a feature peculiar to this South African species.

Length, 3 mm.; width, 1; mm.
