(4) 4. — Some South African Parasitic Hymenoptera of the families Evan- tidae, Bracenidae, Alysiidae and Plumariidae, in the South African Museum with a Catalogue of the known species.'!) — By CHARLES T. BruEs. Some time ago, I received from Dr. Ib Peringuey, the director of the South African Museum, a quite extensive collection of parasitic Hymenoptera belonging to the families Hvaniidae, Braconidae and Alysiidae.’ Since then Dr. Peringuey has made several other smaller sendings of material more recently accumulated by the Museum. He also compared many of the specimens with the types of species des- cribed by Cameron in 1906 and in addition sent me some types and co-types for examination. With all of this material, [ have been able to recognize a large number of species previously described from South Africa, as well as a few first discovered in Equatorial Africa. In addition there were a number of forms not hitherto described. With the exception of two or three species, all those considered are from the South African ‘(or Cape’) region, including that part of the continent south of the Zambesi and Cunene rivers. In the Catalogue of species included in the present paper, this boundary has been adhered to, and I have listed all of the described species known from this region, belonging to the Hvaniidae, Braconidae, Alysiidae and Konowiellidae. Some Stephanidae have been sent to me, but the material in this family was so limited that it has seemed best not to include it in the present consideration. The family Ko- nowiellidae, based upon the Neotropical Plumarius (= Konowiella?) is without doubt not a close relative of the other families mentioned, but as Plumarius was first described as an EHvaniid and later placed in the Braconidae, it did not seem out of place to include it in this paper, particularly as its discovery in Africa is quite unexpected. By far the greatest number of South African parasitic Hymenoptera have been described by Cameron in several extensive papers. First, in 1905, he dealt with the collections of the Albany Museum in Grahamstown; in 1906 with those of the South African Museum; in 1909 and 1910 with those of the Royal Zoological Museum in Berlin; and in 1941 with those of the Transvaal Museum. In addition to these he published several shorter papers in various other journals. 1) Contributions from the Entomological Laboratory of the Bussey Institution, Harvard University, No. 171. (1) 2 f Annals of the South African Museum. Fortunately Cameron’s descriptions are usually rather extended and his species can usually be recognized. In these same papers he erected a considerable series of genera, some of which have been shown to be synonymous or invalid. The same is true of some of his species, particularly in so far as synonymy is concerned. In various papers, mainly between 41905 and 1914, Szépligeti published descriptions of many forms, the majority from Equatorial Africa although there are some South African species and I have recognized others in the material before me. The descriptions of this author are often extremely brief and unsatisfactory. Several of the earlier Hymenopterists have described South African species of the families here dealt with but aside from a quite con- siderable number by Brullé (1846) and some by Holmgren (4868) they are very much scattered. All of these papers, I have re-examined in the light of the present material and have been able to place a number of the species of these earlier authors. Famity EVANIIDAE. ODONTAULACUS, Kieffer. ODONTAULACUS AFRICANUS, Sp. nov. @. Length 10 mm.; ovipositor about 6 mm. Black; upper side of first segment of abdomen, except at base and apex, bright fulvous; legs, except coxae, trochanters and tarsi, fulvo-ferruginous. Wings infuscated, strongly so on the apical half. Head long behind the eyes, almost as thick as broad when viewed from above; shining above, with large, well separated punctures; front strongly transversely convex above the antenae, with only a very slight median impression; its surface punctate like the vertex; facial impression between antenna and eye deep, shining and impunctate below; clypeus coarsely punc- tate, shining, with a short median tooth on its anterior margin; oral margin at sides of clypeus smooth and shining; malar space punctate, about one third as long as the width of the eye; head behind more sparsely punctate than infront. Eyes bare. Middle lobe of mesonotum coarsely transversely ridged, impressed medially in front and faintly so behind on basal half: lateral lobes coarsely reticulate, more or less transversely: scutellum transversely ridged at middle, punctate on sides; propodeum before the petiole similarly ridged, more or less areolate on apical slope and very finely rugose-reticulate on the sides. Neck of prothorax shining, coarsely, sparsely punctate; propleura Ch. T. Brues, Some South African Parasitic Hymenoptera. 3 more or less obliquely reticulate or areolate; mesopleura confluently punctate, smooth along the posterior margin and more or less reti- culate along the anterior margin; metapleura coarsely confluently punctate above; finely reticulate-rugose below. Hind coxae rugose- punctate, more or less distinctly transversely rugose apically. Ab- domen of the usual form. Tarsal claws slender with two teeth below before apex, both acute, the second much the larger and very close to the apex, the first well removed from the base of the claw; tibiae very distinctly spmulose. Wings with the second section of the radius twice as long as the first and half as long as the second; cubitus arising just above the middle of the basal vein; stalk of first discoidal cell nearly as long as the first recurrent nervure; second cubital cell twice as long below as above, receiving the recurrent nervure at its middle; upper third of second transverse cubitus present, very oblique ; discal venation of hind wings distinct. Type from Matroosberg, Ceres District, Cape Province (3500 feet) (R.M. Lightfoot), January 1917 This is the first member of the genus to be discovered in the Ethiopian region, in fact, the whole subfamily Aulacinae is practically absent in this part of the world. It is not very typical in the form of the tarsal claws, upon which the genera are to a great extent founded. The teeth are longer than is usual in other members of the genus and approach those of Pristawlacus, which, however, always has at least three teeth. Of the various species which I have seen itis most similar to O. bilobatus Prov., from North America, and that species too has long, acute tarsal claws. It is an interesting addition to the South African fauna. GASTERUPTION, Latreille. GASTERUPTION JOHANNIS, Cameron. Ann. 8. Afric. Mus., vol. 5, p. 24. (1906). The type has the first discoidal cell triangular, not four-sided and the species is wrongly placed in Kieffer’s key (Das Tierreich, p. 252). Tt falls next to G. sanguineum Kieff. also from Cape Province but the two species appear to be distinct and separable as follows: Propodeum coarsely transversely striate; metapleura and upper half of meso- pleura punctate-reticulate ; : . G. sanguineum Kieff. Propodeum reticulate; metapleura reticnlster mesopleura reticulate, more coar- sely so below and with a dull smooth space anteriorly G. johannis Cam. The length of the ovipositor is 12 mm. and the body 14 mm. in johannis. 4 Annals of the South African Museum. GASTERUPTION PULCHRIPENNE, Cam. Ann. 8. Afric. Mus., vol. 5, p. 23. (4906). The mesonotum is rugose-reticulate, but not noticeably transversely so; the collar is about as long as the distance from the teeula to the anterior border of the mesonotum; the propodeum is reticulated over its entire surface; the first discoidal cell is large, nearly twice as long as the second; the head is very long behind the eyes and the ocelli are close together, far removed from the occipital margin. GASTERUPTION FLAVONOTATUM, Kieff. Bull. Soc. Hist. Nat., Metz, vol. 3, p. 94 (1911). One female from Barberton, Transvaal, April, 1911 (H. Edwards). This was originally described from Willowmore, Cape Province. GASTERUPTION FUSCIPENNE, Sp. nov. QO. Length 14 mm.; ovipositor 13-14 mm. Black, with the humeri, entire pleurae, sides of second and third abdominal segments and all tibiae (darker externally) rufous or rufo-ferruginous, wings strongly infuscated except on the basal third. Head comparatively short, broadly rounded and but little narrowed behind, the temples barely as long as the width of the eye; hind margin strongly carmate below, more weakly so above; surface opaque, leathery, bare except for some short white pubescence along the sides of the face; cheeks nearly as long as the pedicel of the antennae; posterior ocelli slightly closer to the eye than to one another and twice as far from the occipital margin as from one another. Antennae rather stout near the middle, fourth and followimg joints clothed with minute, dense, spiny pubescence; scape as long as the third joint; second slightly over half as long; fourth slightly shorter than the second and third together, nearly three times as long as thick; following very gradually growing shorter except the apical joint. Antennae inserted just below the middle of the eye. Collar as long as the lower edge of the propleura, shorter than the distance from the humerus to the tegula, irregularly punctate above, pronotum with a rather large, acute tooth at each lateral angle. Mesonotum nearly twice as long as wide, with a transverse sculpture composed of punctures and irregular striae combined. Scutellum with fine shagreened sculpture medially, with a lateral punctate line, outside Ch. T. Brues, Some South African Parasitic Hymenoptera. a of which it is coarsely, obliquely striate. Propodeum finely punctate- reticulate, with a distinct median shining ridge. Pleurae almost without pubescence, except for fine sparse whitish hair on the meso- and metapleurae. Propleura leathery, except for the usual horizontal and vertical crenate lines; mesopleura finely rugose, with a smoother area anteriorly below and some indistinct, oblique striae near the tegula; metapleura similar, with some oblique striae near the base of the hind wing. Abdominal petiole slightly longer than the thorax. Ovipositor brown; its sheaths black, with the apices white. Hind coxae strongly transversely striate above; faintly obliquely striate on the sides and leathery below; hind tibiae stouter than usual. Anterior discoidal cell four-sided, but with the outer side very oblique; lower side Jess than two-thirds as long as the upper which is shghtly shorter than the first section of the radius and three times as long as the height of the cell. Two specimens from Cape Town (R. M. Lightfoot) Jan. 19135. This species is related to G. aethiopicum Stadelmann and G. tenwi- cauda Kieffer, from both of which it differs in the sculpture of the mesonotum, unicolorous hind tibiae and darker wings. GASTERUPTION PERINGUEYI sp. nov. Q. Length 14 mm.; ovipositor 16 mm. Black or piceous, with rufous markings on the head and thorax; wings slightly infuscated. Head with the sides of the clypeus, malar space and mandibles, except tips, rufous; lower part of propleura, its apex near the tegula, humeral angles of mesonotum and articulation at base of abdominal petiole rufous; tegulae rufo-piceous; outer surface of four anterior tibiae and the first joint of their tarsi white; hind tibiae with an incomplete annulus at base, and a spot at tip of their first tarsal joint, white; sheaths of ovipositor white at tips. Head one-half longer than wide, narrowed behind the eyes, the part behind the eyes less than half the length of the eye; occipital rim barely evident above; front and vertex subopaque; paired ocelli nearer the eye than to one another and farther from the posterior margin of the head; face subshining, silvery pilose at sfdes; first flagellar joint slightly longer than the scape and nearly twice as long as the two preceding together ; following decreasing in length. Malar space almost wanting. Neck long, but shorter than the distance of the tegula from the front border of the mesonotum, shining and finely cross-striate in front; anterior angles of propleura each produced into a strong tooth, its surface reticulate medially, shagreened around the border. Meso- 6 Annals of the South African Museum. notum with large widely separated punctures on the disc, with distinct transverse ridged sculpture before and behind; parapsidal grooves well impressed. Scutellum nearly smooth medially, very finely reticulate-punctate laterally. Propodeum with a median shining ridge, on the sides coarsely irregularly reticulate, shagreened anteriorly at each side of the insertion of the petiole. Hind coxae finely, trans- versely striate and shining above, dull and granulate below; almost as long as the propodeum. Petiole very long and slender, fully as long as the entire thorax, its surface opaque, finely granulate, without any striation; second and third segments each half as long as the petiole; remainder of abdomen more shining. Hind tibiae rather less strongly clavate than usual; hind metatarsus as long as the fol- lowing jomts together. First discoidal cell four-sided, one-third as long as the first section of the cubitus which arises well below the junction of the median and basal veins; its lower side two thirds as long as the upper. Type from Cape Town, Cape Province (Péringuey), 1915. This species is similar to G, punctulatum Schlett. differing in the sculpture of the mesonotum, hind coxae, and head, and in the color of the abdomen. The form of the first discoidal cell and the origin of the cubitus are also different. GASTERUPTION CRASSIVENTRE, Cameron. Ann. 8. Afr. Mus., vol. 5, p. 28. (4906). The head is unusually short and broadly rounded behind and the entire body is extremely stout. The first discoidal cell is not dis- tinctly four-sided, and consequently the species will not run out correctly in Kieffer’s table in ‘Das Tierreich”’. (ZASTERUPTION FOSSATUM sp. nov. Q. Length 10 mm.; ovipositor nearly as long as the body. Almost entirely black or dark piceous. Mandibies, except teeth, and four anterior legs beyond the knees, excepting a darker band on the middle of the tibiae, brownish-yellow; tips of first, second and third segments obscurely ferruginous or rufous; hind tibiae obscurely pale brownish at base; hind metatarsi fuscous; wings nearly hyaline; sheaths of ovipositor entirely black. Head long and narrow, nearly twice as long as broad, almost semicircularly rounded behind the eyes; upper surface shining and polished; face densely silvery pilose on the sides, between which it is subopaque and minutely punctulate ; Ch. T. Brues, Some South African Parasitic Hymenoptera. 7 malar space short, but distinctly present; occipital carina almost wanting; posterior ocelli as far from one another as from the eye, nearly twice as far from the occipital margin. Antennae with the first four joints of about equal length although the third and fourth, which are strictly equal, are each about one-fifth longer than the basal ones; following to ninth about of equal length, but becoming thicker till the ninth is about one-half longer than wide. Neck about one fourth shorter than the line from humerus to tegula, its surface shining, finely punctate. Mesonotum before the furrows shining, with deep, sparse, coarse punctures irregularly disposed; behind the furrows finely punctate with a few large punctures intermixed and almost impunctate on its posterior part. Scutellum also shining, nearly impunctate. Propodeum very finely rugose-reticulate, with a broad median sulcus, deepest behind, the center of which is smooth and polished. Hind coxae shining, very minutely transversely acicu- late. Abdomen of the usual form, sub-shining, the petiole nearly as long as the thorax. Prepleura almost smooth, except for a small triangular, reticulate area behind; mesopleura and metapleura finely rugose punctate. Thickened portion of hind femora rather slender. First discoidal cell distinctly foursided; cubitus arising at the same point as the basal vein; first discoidal cell one third as long as the first section of the cubitus. Type from Mfongosi, Zululand (W. E. Jones) Dec. 1916. This species may be readily known by the sulcate metathorax and the nearly equal first four antennal segments. TRICHOFOENUS, Kieffer. TRICHOFOENUS PEDICELLATUS, Sp. Nov. Q. Length 11 mm.; ovipositor 6 mm. Black, three basal segments of abdomen rufo-piceous; spot at base of all tibiae pale yellowish; extreme apex of four anterior tibiae, basal three joints of front tarsi and half of basal jot of middle tibiae, pale yellow; antennae piceous brown, black at base; wings hyaline, with a brownish tinge.

Neck very long, one fourth longer than the distance from the tegula to the anterior margin of the mesonotum ; its surface coarsely shagreened. Mesonotum and scutellum shagreened, sub-shining; parapsidal grooves indicated by crenate lines; scutellum separated by a smooth, straight, grooved line, preceded by a crenate eroove that extends laterally and forward past the tegula; lateral crenate furrows of scutellum not very deeply impressed.

Wings with the cubitus arising’ just below the basal vein; second and third sections of radius equal, each one-fourth longer than the first; first discoidal cell two- fifths as long as its petiole, scarcely four-sided, the very oblique apex nearly as long as the lower side. Abdominal petiole slightly longer than the thorax; abdomen rather dull and more distinctly pubescent than usual, as is the entire body. Sheaths of ovipositor black, except for an obscure rufous spot at the extreme tip. Type from Mfongosi, Zululand (W. E. Jones), February 1914. The eyes are distinctly hairy and the species belongs to this genus as defined by Kieffer. It is most closely related to TJ. scutilicauda Kieffer from Australia. EVANIA, Fabricus. EVANIA APPENDIGASTER, Linné. There are numerous specimens from Durban and Cape Town. EVANIA PERINGUEYI, Cameron. Ann. 8. Afr. Mus., vol. 5, p. 19. (4906). This is undoubtedly the widespread E£. appendiyaster L. The type is identical structurally, but differs in the paler color of the legs, parts of the body and venation of the wings, due evidently to its being a teneral, not fully colored specimen. Ch. T. Brues, Some South African Parasitic Hymenoptera. 9 EVANIA FULVOSPINA, Cameron. Anny oa Ati Mus: vols Oss dln GldOG): In addition to the type from Cape Town there are three specimens from Mfongosi, Zululand (W. E. Jones) and one from Pilgrim’s Rest, Transvaal (L. Schunke). The parapsidal furrows are not clearly defined, but are present in the type, which is a female and in the female from the Transvaal. In the Zululand examples, all males, they are somewhat more distinct. In the male the abdominal petiole is much longer, nearly twice as long as the upper edge of the propodeum. This species is evidently very similar to the European EF. incerta Kieffer, which I have not seen. EVANIA RUFISCAPA, Sp. Nov. oO. Length 36 mm. Black, first three joints of antennae below and the four anterior tibiae rufous; wings hyaline, venation paler than usual, except near the costa; tegulae rufo-piceous. Head and thorax shining, only very sparsely white pubescent above, more strongly so on the sides. Front faintly excavated above the antennae and with a trace of a carina on each side from the base of each antenna up- ward toward the ocelli; rugose-punctate, more finely so medially and with indications of vertical striae or aciculations; vertex with rather large, irregular, scarcely confluent punctures; ocelli In a very low triangle, the posterior pair as far from the posterior margin of the head as from one another and only half as far from the eye; face strongly convex, with rather coarse irregular striae converging toward the mouth, with a groove extending from the inner base of each mandible nearly to the eye; cheeks striate like the face, less than half as long as the eye; head behind smooth and polished. Antennal scape as long as the following two joints; second joint scarcely longer than wide, half as long as the third; fourth fully as long as the second and third together and the following about three times as long as thick ; mesonotum with distinct, deeply impressed parapsidal furrows ; with large, shallow, well-separated punctures; smooth along the sides; scutellum with similar, more or less confluent punctures. Propodeum with its posterior surface nearly vertical and slightly concave, finely reticulate before the petiole; coarsely so elsewhere as are also the metapleurae. Mesopleura with the polished space occupying almost all of its upper half. Metasternal process long, with short, divergent arms. Petiole of abdomen twice as long as the space separating it from the scutellum; rather finely and somewhat irregularly grooved 10 Annals of the South African Museum. longitudinally, except at the extreme base. Legs rather long, hind tibia and femur together as long as the body; hind tibiae distinctly spinulose on the outer surface, longer spur slightly over half the length of the metatarsus; tarsal claws bifid at apex. Basal vein parallel with the subcosta on its upper two thirds, but not unusually close to it; cubitus arising near the upper end of the basal, so that the upper section is only half as long as the transverse cubitus; the latter but little more than half the length of the first section of the cubitus; first recurrent nervure (transverse discoidal of Kieffer) suddenly bent upward at tip; apex of radial cell blunt, the radius entering the costa almost at a right angle; six frenulum hooks. Type from Mfongosi, Zululand, Feb. 14914. (W. E. Jones.) This species is related to LE. divergens Kohl. from West Africa, differing in the length of the antennal joints and the form of the radical cell. From #. rimosa Enderlein, also from West Africa it differs by its ~ non-carinate scutellum and in the conformation of the basal joimts of the antennae. It is also much smaller than either of these species. PROSEVANIA, Kieffer. PROSEVANIA AFRA, Kieffer. Ann. Soc. Ent. France, vol. 80, p. 157. (4911). Das Tierreich, Lief. 30, p. 63. (1912). Three specimens from Mfongosi, Zululand (W. E. Jones) extend considerably the known range of the single African species which was described from San Antonio in the Congo. The genus is well represented in the East Indies. BRACHYGASTER, Leach. BRACHYGASTER BIDENTATA, Kieffer. Bull. Soc. Ent. France, 1914, p. 504 (diagnosis) Das Tierreich, Lief. 30, p. 36. (1912). (description) A o specimen from Potchefstroom, Transvaal (T. Ayres), another from Bulawayo, Southern Rhodesia, and a third, from Kaapmuiden, Transvaal (R. W. Tucker), Oct. 30, 1918. This species was described from the Transvaal. The Rhodesian example has the third and fourth antennal joints a little longer, the prongs of the metasternal process less divergent and a few striae on the petiole, thus approaching B. minuta, var. aethiopica Kieffer, although it has the sides of the face carinate as in B. bidentata.

OGMOPHASMUS ERYTHROTHORAX (Cameron). Ann. Soc. Ent. Belgique, vol.56, p.371 (1912) (Rhopalospathius). There are two specimens of this species of this species from Mfon- gosi, Zululand (W. E. Jones), January 1917 and March 1917. These may represent a new species but agree well with Cameron’s description. The base of the stigma is white and the head and thorax are both in great part rufous. SuBFAMILY SPATHIINAE. SPATHIUS, Nees. SPATHIUS STRIATICEPS, sp. nov. Q.

Type from Mfongosi, Zululand (W. E. Jones), April, 1916. Three paratypes, from Acornhoek, Eastern Transvaal (R. W. Tucker), November 1918. In the paratypes the striation of the head does not extend above the ocelli, but they appear otherwise to be iden- tical with the type. This species and the following differ from most members of this highly polymorphic genus in the non-globose head, with deeply emarginate occiput. - Ch. T.

There are several species in the present collection which I have referred provisionally to this genus. Some could easily be placed in other genera that have been segregated from the old genus Bracon (sensu auctorum). One or two others might be made types of new genera, but the time does not seem ripe to attempt any grouping that can be of permanent value, for it is very evident that only a small part of the existing species have been studied. The following key will serve readily to distinguish those here included. M. howardi - Viereck from Mozambique is different from any of these species. M. latilineatus and M. propinquus described by Cameron from the. collections of the Berlin Zoological Museum, I have not seen and could not be included in the key. Key to species. 1.

Stigma and venation honey-yellow. Type from ,,Beach” Durban (Natal) (H. W. Marley), 1900. This species will be easily recognized by the color pattern of the wings and long ovipositor. The peculiar form of the very large mandibles and the consequently greatly modified clypeal excavation are not those of a typical Braconine. Taken by itself, the species might seem entitled to generic rank, but I do not doubt that trans- itional species will be found. I have placed it provisionally in Euurobracon as it appears to be similar in the form of the head to E. quadriceps Smith. However, the nervulus is interstitial, whereas in the true Huurobracon it is postfurcal although in Ashmead’s figure (P. U. S. Nat. Mus. vol. 30, pl. 25 (1906) it is shown to be almost interstitial. On this account the genus has been placed in the Exothecinae by Szépligeti and Roman. IPHIAULAX, Forster. This very extensive and highly polymorphic genus is represented in South Africa, as in most of the warmer portions of the world, by a large number of species. Some of these enjoy a wide range, extending from Equatorial Africa to the Cape, while others appear to have a much more limited distribution, at least in the present state of our knowledge. Several of the South African species date back to Brullé’s ‘‘Histoire Naturelle des Insectes Hyménopteéres’” published 1846 and most of these are recognizable from his descriptions which usually include the salient structural characters. So much cannot be said for the descriptions of some of the later hymenopterists and I have been Ch. T. Brues, Some South African Parasitic Hymenoptera, 37 unable to place some species. Fortunately many of Cameron’s species are represented in the material before me, much of which has been compared with Cameron’s types in the South African Museum by Dr. Périmguey. Some of his species I have unfortunately not been able to place as they do not seem to be represented in the present collection and the types are not available for comparison. The same is true of several of Szépligeti’s species. Omitting these and a few others, I have compiled a key which will, I think serve for the identification of the remaining species known to occur in South Africa, including a few which are undoubtedly new. Szépligeti has attempted to divide Iphiaulax in a number of genera or subgenera, but these are not taken into account, as I do not believe that they are defined by sufficiently clear-cut characters to assist in the classification of the group. On the other hand, the following table is artificial and makes no attempt to group the species according to their natural affinities. Key to species of Iphiaulax (sens lat.). 1.

Radial vem ending not far before the wing-tip, its last section straight, longer than the other two together; cubital vein straight at the base; second cubital cell slightly wider apically, its apex half as long as its upper edge, stalk short; nervulus interstitial. Type from Salisbury, S. Rhodesia, January 7, 1917: paratype from Mfongosi, Zululand (W. E. Jones), March 1917, and a third female from Otjituo, S. W. Africa, (R. W. Tucker), Jan. 1920. A label atta- ched to the type indicates that the species is parasitic upon ‘‘Gono- metra sp.” Two males from Otjituo, 8S. W. Africa (R. W. Tucker), Jan. 1920 appear to be this species, but have the fifth segment uni- formly regulose, as does a third male from Tsumeb, 8. W. Africa (R. W. Tucker), Dec. 1919. IPHIAULAX THISBE, sp. Nov. QO.

Numerous specimen, from Mfongosi, Zululand (W. E. Jones) belong to this species. It is evidently similar to the variable I. (Lyobracon) tesmanni of Szépligeti, but with the basal median area of the second segment not smooth. J. rosa Cameron cannot be more than a variety. The species varies much in size and color. IPHIAULAX LONGICOXIS, Cameron. A female from Windhuk, 8S. W. Africa (R. W. Tucker), Dec. 1919 agrees perfectly with Cameron’s description. IPHIAULAX PLURIMACULATA, Brullé.

In general structure, this species is very similar to several of those included in the group with red stigma. The fourth and fifth seg- ments lack the smooth rim along the posterior margin, however, a character present. in the ohterwise closely similar species.

IPHIAULAX MACULIFRONS, Ritsema. This species described from the West Coast, near the mouth of the Congo, I have been unable to recognize in the material at hand. It is rather crudely illustrated in color, and falls in the group of species with red body and stigma. Whether either is distinet from the forms here listed, is impossible to say, without an examination of the types. IPHIAULAX KREBSI, Cameron. I have not seen this species, and have been unable to include it in the key. It was described from a male and is apparently very close to 1. havilandi Cameron. 64 Annals of the South African Museum. BrAcon Inctsus, Brulle. This is evidently similar to I. spilonotus Cameron and J. pandora n. sp., but it differs from both in the sculpture of the abdomen. I cannot be convinced that there is as much variation in sculpture in the species of this group as Cameron has been led to believe (Ann. South African Mus., vol. 5, p. 48 (1906), although there is unquestionably so much variation in the color and maculation of the head and thorax, that these characters cannot be relied upon to distinguish species. I suspect that it is the species I have designated as J. incisus. Br. in section 56 of the key to species. but may be incorrect in this interpretation. BrAcoN coccINEus, Brulleé. This is evidently an Iphiaulax, but I have not been able to recognize it, although Brullé refers to it as abundant and Cameron speaks of it as occuring in South Africa (Ann. South African Mus., vol. 5, pp. 49 and 52 (1905)). Brulle’s remarks may have been based upon specimens of more than one species, but at any rate his des- cription of the sculpture of the abdomen cannot refer to any South African species that I have seen. IPHIAULAX PECTORALIS, Szépligeti. I have not seen this species, and the description is too incomplete to enable me to insert it in the key. IPHIAULAX (Campyloneurus) SEMILIS, Szépligeti. From the very short diagnosis, I cannot place the species, further than to know that it does not appear to be in the material before me. PLAXOPSIS, Szépl. PLAXOPSIS NITIDULA, sp. Nov. 2. Length 10 mm., ovipositor as long as the body. Entirely rufous, except the antennze and ocellar triangle. Head above and apices of tarsi more or less blackened. Head transverse, one-half broader than thick, the temples broadly rounded; front impressed above the base of the antennz, each of which is placed upon a distinct tubercle; face below antennz with an oblique projection which bears two closely approximated grooves which receive the antennal scapes when they are bent downward; in lateral view the upper surface of this projection is parallel with the longitudinal axis Ch. T. Brues, Some South African Parasitic Hymenoptera. 65 of the eye; face below and at the sides of the elevation rugose reti- culate; malar space half as long as the width of the eye, with a distinct furrow; head above and behind smooth and polished. Antennae slightly longer than the body, gradually tapering to apex; scape evenly widened from base to apex, nearly three times as long as thick at tip; third joint one-half longer than thick; fourth quadrate, following very gradually shorter. Mesonotum scarcely trilobed, the furrows shallow in front and not impressed behind; scutellum sub- triangular, smooth, quite strongly convex. Propodeum smooth, po- lished, without furrow, convex. All pleurae highly polished, propleura with a shallow oblique impression that extends over the pronotum as a deep impressed line; mesopleura with a furrow next to the tegula and another extending trom the root of the hind wing toward the coxa, which together marks off a raised space near the tegula; metapleura separated from the propodeum by a very deep groove that bears a prominent fovea in front of the spiracle which is broadly ovate. Entire abdomen smooth and polished, as long as the head and thorax; first segment as long as broad at apex, its middle portion not very convex, lateral concave area of equal width, limited externally by a carina, lateral triangles strongly concave. Second segment with the basal area as broad as long, over half as long as the segment, produced apically as a slender pomt and margined laterally by short oblique, foveate striae; near the base with a trans- verse impression on each side that curves back laterally to extend nearly to the posterior corner; hind margin curved forward at the sides, but scarcely emarginate medially; suturiform articulation very broad, coarsely striated except at sides; anterior corners of third segment large and broad, separated by a striate groove; fourth seg- menth with a crenulate line at base, its lateral angles not separa- ted; as long and distinctly wider than the second segment which is more than twice as wide as long; fourth and following segments gradually shorter and rapidly narrower, so that the apex of the abdomen is acute. Legs rather stout and strongly hairy; anterior tarsi one-half longer than their tibiae; tarsal claws simple. Wings black; median and submedian cells each yellowish brown along the anterior border; base of radial cell, nearly all of first cubital cell, spot at base of parallel vein and cloud along second transverse cubi- tus, yellowish; also a triangular hyaline spot just outside the lower apical corner of the first cubital cell; hind wing with a yellowish spot anteriorly at apical third; costa and edge of stigma rufous; lower part of stigma yellow. First discoidal cell with a short petiole above, cubitus subangulate at base; recurrent nervure entering the 5 66 Annals of the South African Museum. first cubital cell very near its tip; second cubital cell shghtly widened apically, the second transverse cubitus half as long as the second section of the radius; third section of the latter scarcely as long as the second; radial cell nearly attaining the wing tip. Type from Stella Bush, Durban, Natal (Marley), January 1915. This might easily be mistaken for a member of the polymorphic genus Iphiaulax (sens. lat.) were it not for the prominent subantennal tubercle. The form of this tubercle, the longer scape and shorter, not carinate, first abdominal segment are quite different from Plaropsis sjostedti Szép. from the Cameroons, and at first I regarded P. nitudula as a Lasiophorus. From P. nitens Szép. the present species differs in having the corners of the third abdomlnal segment distinctly separated. Both genera are separable from Chaoilta by the absence of a spine high up on the face next to the antennae. CHAOILTA, Cam. CHAOILTA AMPLIFICATA, Sp. Nov. Q. Length 20 mm., ovipositor 10 mm. Head, thorax, abdominal petiole, spot at base of second segment and legs, except hind tibiae and tarsi, fulvous yellow; antennae, abdomen beyond petiole and hind legs beyond the femora black; wings bright fulvous on basal third; black beyond, except for a triangular fulvous spot which includes the first cubital cell and most of the stigma, and three hyaline spots, one just below the lower apical angle of the first cubital cell, another below the base of the parallel vein and another surrounding the second transverse cubitus; hind wing fulvous on basal half, less strongly so behind. Head scarcely broader than thick, behind the eyes long and broad, then rather sharply narrowed: ocellar triangle small, the ocelli separated by their own diameter ; vertex excavated above the antennae, the basin with a median carina and indistinctly margined laterally by an obtuse rim; antennal tubercles well developed; intra-antennal spine as long as the diameter of the flagellum, followed below by a pair of toothlike processes and lower down by an oblique lamella that is concave above; face coar- sely transversely striated above, nearly smooth at the sides below; malar furrow one-third as long as the eye; head above and behind smooth; head more strongly hairy than usual, especially on the face. — Antennae about as long as the body; scape stout, barely twice as long as thick, obtusely toothed at apex; first joint of flagellum nearly twice as long as the second which is but little longer than thick; following joimts rapidly becoming transverse, with the sutures between Ch.

Mesonotum with weak furrows anteriorly and none behind; middle lobe very weakly convex in front, flat behind; scutellum with a delicate foveate line at base. Propodeum smooth, convex, not furrowed; spiracles oval. Petiole of abdomen slightly more than twice as long as broad at tip, which is twice as wide as the base; median lobe gently raised, ovate-lanceolate, minutely roughened, with a median raised line on apical half and some irre- cular longitudinal wrinkles at tip; sides of segment narrow, flat, the carina placed at the extreme lateral edge. Second segment one-half wider at base than at apex, two-thirds as long as wide at tip; basal median area rounded, convex, opaque, with some short longitudinal striae at apex and with the tip prolonged to the tip of the segment as a strong median carina; median portion of segment sculptured by broken, coarse longitudinal lines, the sides smooth. concave, the two separated by an oblique line running from the anterior angle somewhat toward the center of the posterior margin; also a small concave area basally at each side of the median area; hind margin of second segment curved forward laterally and emarginate at the extreme center; third and fourth segments of equal length, each considerably shorter than the second and with a median carina; basal corners of third large, triangular smooth, of fourth smaller and more transverse; third coarsely longitudinally striated except at tip; fourth similarly sculptured on basal half; suture at base coarsely striated; sixth and seventh much narrowed, smooth, the entire abdomen lanceolate, but little wider than the thorax and as long as the head and thorax together; sheaths of ovipositor thickly hairy. Pleurae smooth; propleura with an oblique shallow furrow that extends on to the pronotum as a deep groove; mesopleura with two oblique furrows above, metapleura with a fovea anterior to the spiracle. Legs rather strongly hairy; hind tibia one-half longer than the femur ; hind coxae compressed. Cubitus rather strongly bent at base, the first discoidal cell with a long petiole above; recurrent nervure entering near apex of first cubital cell; radial cell very nearly attain- ing the wing tip; second section as long as the third and a little more than twice as long as the second transverse cubitus; second cubital cell faintly widened apically; nervulus interstitial. Type from Mfongosi, Zululand (W. E. Jones), May 1917. This is the first species to be described from the African region. Structurally it is quite similar to the type, C. lameliata Cam. from India, although differing in the form of the facial tubercles and in the extension of the median abdominal carina on to the third and fourth segments as well as by the longer first abdominal segment. 68 Annals of the South African Museum. PLATYBRACON, Szépligeti. Doryctocephalus. Cameron Arch. Math. Naturvidens. vol. 30, No. 10, p. 20 (4909). Cameron has described three species of Iphiaulax (platynotus, cal- viniae and erythrostomus) that belong here. One of these, erythrostomus, is represented by several specimens in the collection and is undoub- tedly congeneric with several species of Platybracon in my collection. The facial ridge is less pronounced than in some species, but this character varies within considerable limits in forms otherwise extre- mely similar. P. platynotus Cam. described in 1905 from a male is surely the same as P. erythrostomus characterized a year later from the opposite sex and the species must be known under the earlier name. Doryctocephalus Cameron, 1909 is evidently a synonym, but the type species, D. platynotus appears to be distinct from his Iphiaulax platynotus, 1904. The 1909 species may, therefore, receive the name of P. planinotus nom. nov. SCHIZTOBRACON, Cameron. Ann. South African Mus., vol. 5, p. 70 (4906). Roman, Ent. Tidskr., vol. 31, p. 488 (1910) (Tricvelopyge). This genus is quite distinct by the form of the fifth segment (not sixth as stated by Cameron). It resembles Rhytimorpha at least in the modification of this segment, but the margin is excised, not toothed; the radial cell is longer than in Rhytimorpha, but does not nearly attain the wing tip and is hence shorter than in Odontogaster ; the second cubital cell is slightly widened apically. Tricoelopyge Roman is congeneric, but probably represents a second species. SCHIZTOBRACON ORNATIPENNIS, Cameron. Ann. South African Mus., vol. 5, p. 70 (4906). Latilobatus. Cameron Arch. Math. Naturvidens., vol. 30, No. 10, p. 24 (4909). A specimen is in the collection from Mfongosi, Zululand (W. E. Jones), February 1917. The submedian cell is very slightly longer than the median, but the genus undoubtedly falls in the Braconinde. The specimen before me agrees exactly with the original description except that the mesonotum is entirely black and the propleurae are black below. It also has the middle tibiae and tarsi black as in S. latilobatus, which is unquestionably only a slight color variety. Ch. T. Brues, Some South African Parasitic Hymenoptera. 69 ) y .

Length 6-7 mm. Bright rufo-ferruginous, the antennae, ocel- lar area and sheaths of ovipositor black. Wings fuscous, with paler, yellowish brown markings. From the base nearly to the basal vein pale, then with a fuscous area in the base of the first cubital and all of the discoidal cells, just beyond with a narrow hyaline band, beyond fuscous except for hyaline line on second transverse cubitus; basal two-thirds of stigma yellow, veins piceous. Head shining above, the ocelli in a small triangle, temples rather short, rounded, the head nearly twice as broad as thick; front weakly excavated; face finely punctate, clypeus with its upper margin indicated by a fine raised line. Eyes of moderate size, oval; malar space half as long as the eve, with a shallow, but distinct furrow. Antennae notice- ably shorter than the body, many joimted, but with the joints all short; scape simple, oval, less than twice as long as thick; three basal joints of flagellum nearly equal, less than twice as long as thick; joints beyond to the tapering tips of antennae, becoming qua- drate. Mesonotum smooth, with deep parapsidal furrows, the middle lobe protuberant; scutellum triangular, convex with a punctate line at base; propodeum convex, smooth. Pleurae shining, smooth, mes- onotum with a broad, deep groove below the tegulae; spiracular groove of metapleura absent anteriorly. Abdominal petiole strongly protuberant medially behind, the central portion rugose, bounded laterally behind by a broad groove; spiracular carina strong, entire; lateral groove deep, rugose. Remainder of abdomen rugose; broadly 70 Annals of the South African Museum. oval, twice as long as wide; no longitudinal striations; second seg- ment longer than the third, with a small triangular, nearly smooth median area, prolonged as a line behind; laterally with a pair of deep striate grooves that converge behind; suturiform articulation rather narrow, but strongly crenulate; anterior corners of third seg- ment very large, but indistinctly separated; those of fourth and fifth respectively smaller and more distinctly separated, the sutures at the base of these segments deep, striate; fifth segment slightly lon- ger than the fourth, its apical margin rounded, the lateral edge more than half as long as the median line; teeth on margin broad at bases, rather irregular. Nervulus interstitial; radial cell nearly reaching the wing tip; third section of radial vein as long as the others combined, second four times as long as first and more than twice the length of the second transverse cubitus; first discoidal cell but little narrowed basaily, with a rather long petiole above; base of cubitus straight; recurrent nervure received at tip of first cubital cell; second cubital cell parallel. Ovipositor two-thirds as long as the abdomen. A female from Mfongosi, Zuzuland (W. E. Jones), April 1916, and another from the same locality, May, 1917. This species is most nearly related to O. abyssinica Szépligeti, but is evidently quite distinct. ODONTOGASTER MINOR, Szép. Two specimens from Mfongosi, Zululand (W. E. Jones), May 1916 and April 1917. ODONTOGASTER UNIFORMIS, Sp. nov. QO. Length 6 mm. Bright rufo-ferruginous; antennae, spot at each side of ocellar space, but not the space between the ocelli, and sheaths of ovipositor black; wings uniformly dark fuscous, with an oblique hyaline streak at the basal angle of the second cubital cell and another along the edges of the second transverse cubital vein; stigma and veins black. Structurally almost identical with O. spinosa Cameron and differing only as follows: median lobe of mesonotum more prominent; scutellum strongly convex; separated corners of fourth and fifth abdominal segments of equal size; teeth on margin of fifth segment very slender at bases; ovipositor half as long as the abdomen. Type from Mfongosi, Zululand (W. E. Jones), April 1916; another from the same locality, May 1917. This species resembles O. minor in color, but the abdomen is Ch. T. Brues, Some South African Parasitic Hymenoptera. 71 broader, with the middle space of the first segment strongly raised, and with a basal area on the second segment. It is also very much larger.

This species, originally described from the Congo, is represented by a female from Jackal’s Water, Bushmanland (R. M. Lightfoot), October 1911. On account of the dentate apex of the abdomen and general color, this genus resembles Odontogaster, but the radial cell is much shorter, the head much thicker, the eyes round, the impressions on the second abdominal segment divergent behind, the second cubital cell is widened apically and with a long petiole at base, the corners of the third segment are deeply separated, and the apical teeth on the abdomen are less acute. CURRIEA, Ashmead. “Curriera” of Cameron, Szépligeti et al. There are several species of this genus described from Equatorial and South Africa and two are contained in the present collection. The eyes of the female are very large, much as in the males of certain Iphiaulax and related genera. The most remarkable feature of Curriea is, however, the peculiar disposition of the veins surrounding the brachial or lower discoidal cell, which also sometimes contains a chitinized macula like the spots in the disco-cubital cell of the Ichneumonid Henicuspilus. Due to the distortion of this cell the sub- median cell is sometimes distinctly shorter than the median, and the neuration of this area reminds one of that of the Rhogadine, Gyro- neuron and its allies, as already noted by Baker. Just what relation Curriea bears to Aphrastobracon and Hewittella, 1 cannot tell, as I do not know the latter genera in nature. CURRIEA FLAVOMACULATA, Cam. Rec.

Structurally both are almost identical although the basal area of the second segment is larger and more finely striate in the large specimen which also has the abdominal sculpture forming more or less longitudinal reticula- tions. A third female received later from Tsumeb, 8S. W. Africa. (L. W. Tucker), Dec. 1919, agrees exactly with the Rooiberg speci- men in size and sculpture. This genus appears to be very much like Rhamnura Enderlein in many particulars; it does not lack the parapsidal furrows, however. Trachybracon appears to be identical. CHELONOGASTRA, Ashmead. In its typical form this genus is easily recognizable by the pecu- har form of the abdomen and hairy eyes. It was originally based on two Japanese species and I have another from Formosa which appears to be structurally very similar to the type species. Three South African species are included in the present collection but they differ in having the eyes very sparsely hairy, nearly bare, and in lacking a distinct median area on the second segment of the abdomen as well as in the strongly arcuate, not straight suturiform articula- Ch.

Type from Mfongosi, Zululand (W. E. Jones), March 1917. GASTROTHECA, Gueérin. There are several species in-the collection, but I have been unable to identify any of them definitely. Cameron, Enderlein and others have described several species from South Africa and other parts of the continent, some of which should be represented. G. furcata Guerin is, I believe, not represented and probably does not extend so far south. The form of the abdomen has led to the placing of Gastrotheca in the subfamily Cheloninae, undoubtedly an incorrect position. From the form of the mouth, with a large semicircular clypeal opening, immargined head and venation it should be placed in the Braconinae in spite of its superficial resemblance to Chelonus and related genera. The median and submedian cells are of equal length, the radial cell is quite long, although not attaining the wing tip, the second cubital cell is long (twice as long above as it is high) and the submedian cell of the hind wing is very short. Aside from the abdomen, the remainder of the body, head and antennae also show the various more or less indefinable characters of the Braconinae. In Chelonogastra we find in a way a transition between Gastrotheca and typical Braconines, although of course nothing like the extreme abdominal modification of the latter genus. VIPIO, Latreille. I am unable to distinguish satisfactorily the several similar species of this genus without an examination of all the types. Ch. T. Brues, Some South African Parasitic Hymenoptera. 77 ) y }: VIPIO FUMIPENNIS, Cameron. Ann. South African Mus., vol. 5, p. 64 (1906). A male labeled “Vipio fumipennis Cam., sec. type” is remarkable in having the fourth abdominal segment greatly elongate, and very nearly twice as long as the third, with the following very short. Unfortunately the female is unknown. ODESIA, Cameron. Ann. South African Mus., vol. 5, p. 79 (1906). This genus comes near Glyptomorpha and its allies, but the sub- median cell is slightly though distinctly shorter than the median. Otherwise it is almost entirely similar. Cameron makes no mention of the fact that the lateral margins of the abdomen are tuberculate or dentate; at the side of the second segment there are three such projections, a small one near the anterior corner, one at the middle and one before the tip; at the base of the third and fourth are similar tubercles. In a male, probably of another species, from Zululand, these tubercles are present, but not very noticeable. The genus Zalyptogastra Ashmead from Siam has the abdominal segments modified in a similar way, but in this case the submedian cell is longer than the median. Quite possibly Nundinella may be a synonym ODESIA LONGICORNIS, Cameron. ibid its c..2) 805.906): One female from the Junction of the Crocodile and Marico Rivers, Transvaal (R. W.

XENOLOBUS, Cameron. XENOLOBUS RUFUS, Cam. Ann. Transv. Mus., vol. 2, p. 200 (4911)., This remarkable insect was described from a male taken at Pretoria. There is another male in the present collection from Salisbury (J. O'Neill Jan. 13, 1914). The large raised coloured lobes on the sides of the upper surface of the propodeum mentioned by Cameron are in reality composed of a dense brush of erect fine hairs; each shows a convex velvety surface, but the surface to which the hairs are attached appears to be depressed below the surrounding parts of the metanotum. Quite probably these peculiar organs represent some sense organ, or they may be exudate organs like the tufts of orange- colored hairs seen in certain myrmecophilous beetles. I know of no similar structure among the parasitic Hymenoptera, unless it be the coxal scopa present in the female of some species of Amblyteles (Ichneumon). In Xenolobus the tufts do not include the spiracle, which lies just below their outer edge. The tips of the tibiae, tips of the first tarsal jomt and the second and third tarsal joints of the hind legs are noticeably thickened or swollen. SUBFAMILY RHOGADINAE. RHOGAS, Nees.

One specimen from Kar Kloof, Natal, 1915 (Bell-Marley); several from M’Fongosi, Zululand (W. E. Jones). From the description of Disophrys tarsalis Szépligeti (Ann. Soc. Ent. Belgique, vol. 58, p. 1416 (1914), I am inclined to believe that it is this species. DISOPHRYS NATALIENSIS, Szép. Termes. Fiizetek, vol. 25, p. 71 (1902). Two specimens from Salisbury, Southern Rhodesia (1908). This large, rufo-ferruginous species is easily recognizable. DISOPHRYS IRIDIPENNIS, Cam. Xanthomicrodus iridipennis Cameron, Rec. Albany Mus., vol. 4, p. 158 (4905). One male from Inhambane, Mozambique (K. H. Barnard), December 7, 1912 agrees well with Cameron’s description. This species is the type of Xanthomicrodus (Cameron, ¢.c¢., p. 157) which must therefore fall as a synonym of Disophrys. DIsopHRYs LUTEA, Brulle. Hist. Nat. Ins.

Two of the most interesting species contained in the present col- lection are members of this genus. After its discovery in Europe, Helorimorpha was soon found in North America, and a few years later in South, America. In 1909, Cameron described Stictometeorus from South Africa, placing it in the Meteorinae. After seeing the two African Helorimorpha, I feel quite certain that Siictometeorus is properly to be regarded as a synonym. The present locality adds definitely another faunal region, for although the African forms might perhaps be considered as representing a distinct genus or subgenus, they are extremely similar to the other species, showing a closer similarity to the Neotropical H. brasiliensis Brues, than to the European or either of the North American species. Thus in H. brasiliensis and the African species the course of the cubitus forms an unbroken line, while in the others it is angled at the base of the second cubital cell; on the other hand the veins beyond the cells are not indicated in africana, are weakly defined in at least one North American species and quite distinct in brasiliensis. All six known forms are otherwise very much alike, and differ only in the intensity of sculpture, in color and in minute details of wing venation. The two African species may be separated as follows: H. rufa Cameron is probably a third as the mesonotum is black and the antennae black above at base, as in H. bicolor Szép. 1. Antennae honey-yellow, except at tips; third joint as long as the two preceding together; second transverse cubital vein incomplete H, africana sp. noy. Antennae black beyond second joint; third joint shorter; second transverse cubitus complete 3 : : : . H. coffeae sp. nov. HELORIMORPHA AFRICANA, Sp. Nov. o. Length 45 mm. Entirely dull fulvous, the apical three or four joints of antennae black; abdomen ferruginous on apical half; wings hyaline, with a slight yellowish tinge, stigma and venation pale brown.

Antennae 18-jointed; scape nearly as long as the width of the eye; pedicel two-thirds as long; first flagellar joint twice as long as the pedicel, nearly five times as long as thick; following gradually shorter and moniliform, those near apex almost twice as long as thick. Entire thorax coarsely reticulate or areolate as in the other species, the spaces not showing any definite arran- gement. Abdominal petiole long, slender, shghtly curved, thickened just beyond the middle, then gradually narrowed to apex which is but little thicker than the base; spiracle placed distinctly, but not far behind the middle; surface of petiole without distinct sculpture. Body of abdomen shining and polished, the second tergite extending to its tip and far down on the sides and apparently enclosing the venter; elongate oval, half as wide as the thorax and a little higher than wide. Legs with the tibiae and tarsi clothed with short whitish hairs. Stigma rather angulate below; radial cell on the costa two- thirds as long as the stigma, the costal vein extending halfway from its tip to the wing-tip; first section of radius twice as long as the second, the two together as long as the width of the stigma; third section twice as long as the width of the stigma and parallel with the outer edge of the stigma; recurrent nervure interstitial with the first transverse cubitus; second section of cubitus half as long as the first; submedian cell longer than the median by almost the length of the recurrent nervure; second discoidal cell open below and at apex; all veins obliterated almost entirely beyond the cells. Submedian cell in hind wing more than half the length of the median. Type from M’fongosi, Zululand (W. E. Jones), April 1916; paratype from same place, May 1916. The ventral surface of the abdomen is convex and fully chiti- nized, a character suggesting Thaumatotypus and the other genera recently included in the family Myersiidae althongh this is aslo true of some male Euphorinae to which Helorimorpha is without question closely related and next which it was originally placed by Schmiedeknecht, Ch. T. Brues, Some South African Parasitic Hymenoptera. 103 HELORIMORPHA COFFEAE, Sp. nov. oO. Length 45 mm.

Antennae 18-jointed; scape twice as long as thick, as long as the width of the eye; first flagellar joint nearly four times as long as thick; following joimts growing shorter and becoming moniliform, those near apex twice as long as thick. Thorax areolate as usual. Abdominal petiole long, slender, curved, thickened well beyond the middle, then narrowed at apex; the spiracle placed noticeably behind the middle; petiole smooth. Body of abdomen as in the preceding species, wing venation as in the preceding species, except that the submedian cell does not exceed the median quite so much and the second transverse cubitus is evenly developed not hyaline in the middle as in H. africana. Two specimens from Kalesto, Kenya Colony (February 1918). The label indicates that they were bred from coffee and that the species is probably a fruit-fly parasite. The cocoons, which are mounted with the specimens, are broadly oval, made of very heavy, dense white silk and appear rather more roomy than might be expected from the slender build of the insect.

A specimen from Salisbury, Southern Rhodesia (R. W. Tucker), May 1917. The antennae are 16-jointed and the species falls in Szépligeti’s genus Chelonella. CHELONUS, Jurine. A number of South African species have been described, but I am unable satisfactorily to identify the material before me. ASCOGASTER, Wesmael. ASCOGASTER BIPUSTULATA, Sp. Nov. oS. Length 36 mm. Black, with a pair of pale lateral spots at the base of the abdomen; basal third of antennae, mandibles, four 106 Annals of the South African Museum. anterior legs, including coxae, posterior trochanters, base of femora and base of tibiae broadly, dull brown; wings hyaline at base, with a cloud on the apical half, strongest below the stigma; veins fus- cous, stigma black; body clothed with glistening pale hair, especially noticeable on the face, pleurae and legs.

I have been able to examine the type of M. serrata, and find that it is very different from any other Chelonine that I have seen and distinct I believe from any other known genus. The serrations at the apex of the abdomen are small and quite conspicuous, being really due to raised ridges between the reticulate surface of the abdomen. The peculiarities of Minanga lie not here, but in the form of the head, thorax and in wing venation which recall in many respects members of the genus Cardiochiles. The front is slightly Ch. T. Brues, Some South African Parasitic Hymenoptera. 107 excavated, the ocelli very large, in a very flat triangle and occupy- ing most of the space between the frontal excavation and the occi- put; the clypeus is strongly raised with very large foveae at the sides above. The radial cell extends halfway from the stigma to the tip of the wing, the second section of the radius parallel to the costa, the third weakly bent inward at the base and sinuate at apex; the submedian cell in the hind wing is large and broad, more than half as long as the median. PACHYCHELONUS, gen. nov. Rather large for the subfamily. Head very broad and deeply excavated behind; eyes very small, oval, bare; front scarcely im- pressed above the antennae, antennae with more than 30 joints, tapering, the scape elongate; clypeus produced medially into an acute lobe; Mesonotum with deep, broad parapsidal furrows, widely separated behind; scutellum elevated into an acute tubercle, with a deep, striate furrow at base. Propodeum short, coarsely reticulated, posterior angles acutely produced, the spiracle small, circular. Meso- pleura simple, convex. Abdomen short and broad, with three very indistinctly indicated segments; tip simple, rounded, venter concave. Legs stout, hind femora and tibiae swollen apically; tarsal claws pectinate, with three or four long slender teeth within. Wings with the basal vein thickened toward the costa, passing gradually into the parastigma; all cubital and discoidal cells separated; anal cell with a cross-vein, median and anal veins very much broadened basally; anal area broader than usual, with a vein-like thickening along its edge; radial cell of hind wing contracted at the middle. Type P. fulviventris sp. nov. This most remarkable insect differs from any of the known Che- loninaeé in one or more of the following particulars; notably the tuberculate scutellum, thickened veins, anal cross vein, thickened edge to anal area in wing, acutely produced clypeus and pectinate tarsal claws. PACHYCHELONUS FULVIVENTRIS, Sp. Nov. o. Length 85 mm. Deep black, the entire abdomen and hind legs, including coxae, fulvous or light honey yellow; wings black, with a hyaline streak below the base of stigma, a less pronounced light spot near the base of the radial cell and a hyaline dot at the middle of the second transverse cubitus.

Mesonotum smooth and shining with a few minute scattered punctures and with a coarsely reticulated area next to the tegula; parapsidal furrows wide and deep, coarsely foveate. Scutellum with a few large punctures, groove at base coarsely striated, the depressed sides with several deep more or less longitudinal grooves separated by raised lines. Reticulations of propodeum very coarse and irregular. Propleurae coarsely and irregularly striate-reticulate. Mesopleura similarly, but more finely sculptured, and with punctures intermixed; smooth below; along the posterior edge with a coarsely transversely striated furrow. Metapleura reticulate, no subspiracular furrow. Abdomen barely as long as the head and thorax, oval, slightly more than twice as long as wide and as broad as the thorax, divided by faint transverse furrows into three segments of which the first and second are of equal length and the third half longer than the other two combined. First segment not much narrowed basally, one-third wider than long, with a weak cara on each side extending from near the anterior angle straight back to the hind margin; surface slightly concave basally between the carinae; finely and somewhat irregularly longitudinally striate, as are the following segments; second segment widest at tip, half as long as wide; third broadly rounded at apex; lateral and apical margins of abdomen bent under and with a distinct rim.

From the description it is difficult to believe that this insect belongs to the Cheloninae in which it is placed. The long radial cell, distinctly segmented abdomen, interstitial nervulus and long ovipositor seem out of place here and quite likely Tvigastrotheca may be related to the Braconine genera Odontogaster, Caelodontus, etc. GASTROTHECA, Gueérin. This genus does not belong to the Cheloninae where it has been placed. It will be found on a previous page in the subfamily Braconinae. SUBFAMILY SIGALPHINAE. SIGALPHUS, Latreille. One South African species has already been described by Szépligeti, parasitic on Dacus oleae in the Transvaal. A second species is in the present collection. The two may be distinguished .as follows: 1. Legs, almost entirely, and tegulae reddish yellow; front smooth S. dacr Szép. Legs, except knees, and tegulae black or piceous; front sculptured S. simplicifrons sp. noy. SIGALPHUS SIMPLICIFRONS, Sp. Nov. Q. Length 3 mm. Black; clypeus and mandibles, except tips, rufoferruginous; tips of all femora and basal third of tibiae yellowish brown. Wings hyaline, the stigma black, veins piceous. Head fully twice as wide as thick; temples somewhat bulging behind the eyes, then rapidly narrowed to the carina, as broad as the eye-width; ocellar space not elevated, bounded by a weakly impressed line; the posterior ocelli separated by an impressed line; occiput smooth, vertex with some small punctures at the side of the ocelli; front punctate at the sides, the antennal cavities rugose except near the outer edge; face confluently punctate, with a patch of short vertical striae just outside the large clypeal foveae; clypeus with a few large punctures, Malar space one-third as long as the eye, with a broad, 110 Annals of the South African Museum. very shallow, furrow; eyes elongate-oval; cheeks shining and nearly impunctate. Antennae 21-jointed, scape short and slender, as long as the first flagellar joint which is distinctly shorter than the second; third and succeeding rapidly growing shorter, the apical joints sub- moniliform. Mesonotum as broad as long, strongly trilobed, the lateral lobes very convex; parapsidal furrows deeply impressed, finely crenulate, meeting just before the scutellum; lateral lobes smooth, middle one weakly punctate except in front. Scutellar furrow very broad and deep, coarsely transversely striated or fluted, bounded at the sides by a carina; scutellum highly convex, smooth. Propodeum rugose or minutely reticulate, upper angles produced into blunt teeth. Propleurae smooth above, indistinctly striate below, the pos- terior margin with a crenate line, the median furrow also coarsely transversely striate. Mesopleura with a highly convex area extending nearly vertically from below to near the upper edge, next which there is a horizontal elevation below the tegula; between these and also at the lower anterior corner is a punctate space; hind margin with a crenate line before which is a foveate impression near the middle; metapleura reticulate, with a crenate line anteriorly. Hind coxae produced below, but not toothed. Abdomen as long as the thorax, oval, broadest behind, the surface with very shallow, minute reticulation which tends to assume a longitudinal direction; sutures between first, second and third segments faintly indicated at the sides; apex flattened and slightly concave just above the ovipositor. Ovipositor as long as the abdomen, its sheaths sparsely hairy. Radial cell short, no longer than the stigma, strongly curved below, closed, the costal vein extending well beyond it; first discoidal cell sessile above; recurrent nervure entering the cubital cell far before its tip, parallel with the transverse cubitus; cubital vein extending a short distance beyond the cell; submedian cell slightly longer than the median; third discoidal cell open at tip; nervellus very short. Type from Junction of Crocodile and Marico Rivers, Transvaal (R. W. Tucker) February, 1918. This seems to be a typical Sigalphus, although undoubtedly not congeneric with many of the forms that have been placed in this genus. It differs from Fersteria nitida Cameron described from the Transvaal by the absence of longitudinal sculpture on the metanotum and abdomen and by the extension of the cubital vein beyond the cell. With S. daci it is evidently closely allied. Ch. T. Brues, Some South African Parasitic Hymenoptera. 111 Famity ALYSIDAE. IDIASTA, Forst. COELALYSIA, Cam. COELALYSIA LUSORIAE, (Bridwell). Proc.

The species resembles somewhat Alysia goniarcha Cameron, from the Belgian Congo. Bridwell reared it from the same host near Cape Town. HERATREMIS, Walker. HERATREMIS LONGICORNIS, sp. nov. Q.

Type from M’fongosi, Zululand (W. E. Jones), April 1916. This insect has the longest antennae and legs of any parasitic Hymenopteron that I have ever seen, and it is in great part on these peculiarities that I have referred it to Walker’s genus Heratremis known by the type species from Ceylon. Owing to its imperfect 8 414 Annals of the South African Museum. characterization no attempts have been made to locate it and the present species may of course be a quite different insect, for many Alysiidae have the antennae very much elongated. Famity PLUMARIIDAE = (KONOWIELLIDAE),. This family was characterized in 1914 by Bischoff to include a genus of South American Hymenoptera of doubtful affinities. Bischoff described the type Konowiella andrei as a new genus and new spe- cies. At about the same time I received some peculiar Hymenoptera from Argentina and Peru which I was unable to associate with any known genus, until Mr. 8. A. Rohwer called my attention to the genus Plumarius of Philippi described in 1873 (Stettiner Ent. Zeit., vol. 34, p. 299) as an Evaniid. An examination of Philippi’s deserip- tion and figure at once revealed the fact that my insects were closely related, although quite probably generically distinct. They are also very evidently to be placed close to Konowiella, although If cannot be sure whether one or several genera should be recognized in Plumarius, Konowiella and my own series. On account of the form of the radial cell Szépligeti (Gen. Insectorum, fasc. 22, p. 118 (1904) ) has been misled concerning Plumarius which he places in the subfamily Agathidinae of the Braconidae, and regards as proba- bly identical with Neonewrus Haliday. Since then Morley, (Ent. Monthly Mag., vol. 25, p. 93 (1914)) has shown that Neoneurus is identical with Elasmosoma Ruthe, an anomalus Braconid usually classed as one of the Microgastrinae. There can be no doubt that Plumarius, Konowiella and its allies have no close affinities with Elasmosoma (at least the American species probably belonging to Elasmosoma) or with any other Braconidae and it appears that the family Plumartidae is a valid one, probably most closely related, as Prof. J. C. Bradley has suggested to me, to the Zhynnidae. In a later number of the Entomologische Rundschau for the same year (unfortunately not received till after the war) Bischoff described the genus Myrmecopterina, related to Plumarius, from South Africa. Still later, Enderlein proposed the generic name Arvchihymen and the family Archihymenidae for the African insect, and this must fall into the synonomy. With this in mind, I was greatly surprised to find in the present material an undoubted Plumariid from South Africa. This appears to be distinct from the South American forms, and to be identical with Myrmecopterina. Ch. T. Brues, Some South African Parasitic Hymenoptera. 4145 MYRMECOPTERINA, Bischoff. Entom.

Head not very strongly transverse: including the eyes, twice or less than twice as broad as thick; ocelli large or moderate; eyes not very strongly projecting, oval, extending almost to the base of the mandibles; clypeus short and broad; head not striate nor punctate; antennae inserted not far above the clypeus, 13-jointed, pedicel and flagellum clothed with short, stiff white hairs, about as long as the thickness of the antennal joints. Mesonotum with weakly impressed, fine parapsidal furrows and faintly trilobed in front; at the sides with a fine grooved line extending forward from carinae at the sides of the basal scutellar groove, and fading out anteriorly; scutellum moderately convex, without carinae or grooves laterally, except at extreme base where the broad basal groove is limited at each side by a carina. Propodeum gently declivous behind, not areolate, as long as the mesonotum. Abdomen elongate oval, sessile, with six visible, nearly equal segments, terminated at tip by a short horizontal thin plate with rounded apex; claspers elongate triangular, not con- spicuous, as long as the dorsal plate. Wings with the second cubital cell very much reduced in size; first discoidal cell almost as high as long; hind wing with three closed basal cells. Legs slender; tibial spurs rather weak. Type M. filicornis Bisch. This genus differs most strikingly from the South American mem- bers of the family in the form of the head, less prominent, longer eyes, shorter antennal vestiture and small second cubital cell. The two species may be separated as follows. Ocelli larger, separated from the eye by their own diameter; second cubital cell larger, half as long as the height of the first cubital cell; upper section of basal vein one-third as long as the lower. ‘ filwcornis, Bischoff. Ocelli smaller, separated from the eye by twice their own diameter; second cubital cell smaller, one third as long as the height of the first cubital cell; upper section of basal vein one half as long as the lower minor, 8p.

By the kindness of Dr. L. Péringuey, South African Museum, I have been enabled to examine some material of Megaloptera from South Africa, and in the following pages I give the result of my investigations. Only little is known about the Megalopterous fauna of Africa, and only few species are known from that part of the world. In 1867 Mac Lachlan described Chauliodes pusillus (loc. inc.), in 1869 the same author described Chauliodes tenuis from Knysna district, and in 1920 I described Leptosialis africana from the Winterhoek Mountains. At present the following species are known: Fam. SIALIDAE. Sus-Fam. CORYDALINAE. TrisE NEUROMINI. CHLORONIELLA PERINGUEY], n.g. & n. sp. Trine CHAULIODINI. T ZNIOCHAULIODES OCHRACEOPENNIS, n.g. & n. sp. PLATYCHAULIODES PUSILLUS (Mac Lachlan). LEPTOCHAULIODES TENUIS (Mac Lachlan). SuBp-Fam. SIALIDINI. LEPTOSIALIS AFRICANA Esb.—Peters. I have here followed Weele as to the systematical arrangement and with regard to the terminology of the anal appendages of the male. CHLORONIELLA, n. g. Head oblong, eyes prominent, sides of head behind the eyes with a triangular, tooth-shaped dilatation. Antennae as long as three fourths of the length of forewing, serrate (only the male sex is known). 152 Annals of the South African Museum. Wings rather elongate and with rounded apices. Between # and fs three crossveins. Rs with four branches. Most of the crossveins in the disc of forewings thickened in their middle part. Anal appen- dages of the male consist of a pair of upper appendages, of a pair of lower appendages and of a broad genital valve. Genotype: CHLORONIELLA PERINGUEYI, N. sp. As to the venation of the wings this genus is nearly allied to the American genus Chloronia Banks; but with regard to the form of Fig. 1. Chloroniella péringueyt J. anal appendages in the male the genus has more likeness t to the East-Asiatic genus Protohermes Weele. The small number of branches from #s and the peculiar shape of the dilatation on the side of the head give the genus an outstanding position among the Newromint. CHLORONIELLA PERINGUEYI, nN. sp. Head pale brownish yellow. A blackish brown spot between the Insertion of the antennae; ocelli blackish brown. On the vertex a somewhat impressed longitudinal median line. At each side of the vertex a longitudinal jet black streak. Antennae pale greyish brown becoming darker towards apex; basal joint brown, shining. Prothorax one and a half times longer than broad, pale yellowish brown, with a jet black longitudinal streak at each side near the lateral margin. Meso- and metathorax pale yellowish brown with a darker spot at P. Ebsen—Petersen, South African Megaloptera., 153 the base of each wing. Abdomen pale brown; underside of thorax and abdomen yellowish brown. Legs-yellowish brown. Anal appen- dages pale brown with short whitish hairs. Upper appendages, seen from above, obtuse conical, seen from below, cup-shaped; the lower appendages claw-shaped; the genital valve very broad with a pro- longation at each angle and with a semicircular rounded hind margin, which is incised in its middle. Wings hyaline. Venation pale brown. Fig. 2. Chlorontella périnqueyt. Dorsal view of anal appendages of ¢/. Some crossveins in the disc of the forewing either totally or partly black.

TASNIOCHAULIODES, n. g. Head elongate, narrowed behind; the ocelli placed rather close together. Antennae setaceous. Wings broadened towards apex, which is rather acute.

The genital valve rather broad and with rounded angles. Fig. 3. Toeniochauliodes ochraceopennis 3g. Genotype: TNIOCHAULIODES OCHRACEOPENNIS. As to the shape of anal appendages of the male this genus seems to be nearest to the South American genus Protochauliodes. An interresting feature is the forking of M, in the forewing. T £NIOCHAULIODES OCHRACEOPENNIS, N. Sp. Head brown; the ocelli placed in a somewhat darker spot; the ocelli brownish, each of them surrounded by a circle of short Fig. 4.

Prothorax brown, somewhat darker towards the sides, one and a half times as long as broad; the posterior half with a longi- tudinal impressed median line, the front half with a longitudinal median keel. Meso- and metathorax and abdomen brown with very short pubescence. Legs and underside of thorax and abdomen pale brown, tips of tibiae and of tarsal joints blackish. Membrane of forewings yellowish brown; venation yellowish brown with dark brown streaks, which are broadly shaded with brownish. Some of these shadows form rather distlInct spots. Several of the crossveins in the apical part very pale. Costal area rather broad; 20-22 costal crossveins. Membrane of hindwings hyaline and with faint yellow- ish tinge. Venation pale brownish yellow. Costal area narrow and with 17-19 cross veins.

I have at hand a male speclmen from Paarl Cape Div., Octbr. 1919, Rev. G. Hawke leg. (South African Museum) and a specimen without abdomen, but with serate antennae, from the same locality and collected at the same time and by the same collector (pre- sented to me by Dr. L. Péringuey). The hitherto only known specimen of Chauliodes pusillus Mac Lachlan (Journ. Linn. Soc. Lond., 234, 1867; Ann. and Mag. Nat. Hist., 39, 1869) is the type-specimen, which is kept in the collec- tion of the late Mac Lachlan. The locality was unknown, and Mac Lachlan supposed it to be from India. Later on Weele (Col- lections Selys. Megaloptera, 48, 1910) regarded the species to be Fig. 6. Platychauliodes pusillus, Mac Lachlan. Dorsal view of anal appendages of (j. from South Africa, and he also placed Chauliodes tenuis Mac Lachlan (Ann. and Mag. Nat. Hist., 38, 1869) from Knysna district as a synonym of it. I have compared the two above named specimens with the des- cription of Mac Lachland and with a photograph of the type-specimen, reproduced in Collect. Selys. Megaloptera, pl. IV, fig. 36, and I am inclined to consider the supposition of Weele as to the locality of that species to be correct. The two specimens agree exactly with the description and with the figure. There are, however, some differences as to the anal appendages, and I may say, that I am not able to understand the description of them given by Mac Lachlan. The type-specimen has lost its antennae. Weele placed Chauliodes P, Ebsen—Petersen, South African Megaloptera. 157 pusillus in the genus Archichauliodes, which genus besides pusillus contains dubitans Walker from New Zealand and guttiferus Walker from Australia. Especially on account of the serrate antennae and the different form of the anal appendages of the male the species has to be placed in its own genus. Costal crossveins in the forewing 21—22; in the hindwing 19—20. LEPTOCHAULIODES, n. g. Head oblong. Ocelli rather large. Antennae setaceous (sex un- determinable). Wings slender and with narrow costal area. In the forewing 24 is forked, and its first branch coalesces with 1 A for some distance. Genotype: CHAULIODES TENUIS, Mac Lachlan. Ann, and Mag. Nat. Hist., 38, 1869; Weele, Collect. Selys. Megaloptera, 48, pl. III, fig. 28, 1910. The type-specimen of this species is kept in the British Museum, and Mac Lachlan described it as a male. Weele, however, has seen Fig. 7.

Caledon Div., Cape. Jan. 1916, K. H. Barnard leg. Its body is damaged by attack of insects, and therefore its sex is undeterminable. 158 Annals of the South African Museum. The wings of the species are lanceolate and with rather acute apex. The membrane is hyaline, and the venation is brownish yellow with very short brown streaks, which are narrowly and faintly shaded with brownish. Near the base of the forewing a large brownish spot. The membrane of the wings is provided with numerous short dark bristles. Costal crossveins in the forewing 23—26; in the hindwing 22. With some hesitation Weele has placed the species in his genus Archichauliodes. ( 159 ) 3. — Some Mosquitos from Ovamboland, S. W. Africa, and from the Cape Province. — By F. W. Epwarps, F.E.S. (Published by permission of the Trustees of the British Museum). The small collection of mosquitos here noted was sent to me for determination by Dr. L. Péringuey. The Ovamboland material was obtained during a trip made on behalf of the South African Mu- seum by Mr. K. H. Barnard, assistant-director, in the early part of 4920. This material contained the following ten species, which were obtained at the localities mentioned: — Anopheles mauritianus, Grp. Sandup; Otjiverongo. A. squamosus, Theo. Namutoni. A. costalis, Theo. Otjiverongo; Namutoni. A. funestus, Giles. Namutoni. Mucidus scatophagoides, Theo. Nomtele; Ondongua. Aedes (Ochlerotatus) chelli, Edw. Nomtele; Namutoni; Andoni; Otjiverongo. A.

AEDES CHELLI, Edw. 1915. Bull. Ent. Res. vol. 5, p. 277. This is the most interesting species in the list and was present in the collection in some numbers. There was a slight difference from the type (described from British East Africa), the wings having more numerous pale scales, and the fourth hind tarsal seg- ment being entirely dark. Most fortunately a male was collected, and this proves that the species belongs to the subgenus Ochlerotatus, and not to Hcewlex, as might have been expected; the only other Ethiopian Ochlerotatus is the somewhat similar A. fryeri, Theo. 160 Annals of the South African Museum. The male of A. chelli shows the following characters: — _ Palpi longer than the proboscis by nearly the length of the last segment, mostly black, with some scattered pale scales. Median pale stripe of abdomen confined to the last two segments (recalling the similar sexual difference to be found in 4A. rusticus, Rossi). Pale rings at the bases of the first two hind tarsal segments narrower than in the female, that on the third segment absent altogether. Hypopy- gium: Sidepieces with basal and apical lobes both very small, the former with a small and dense pateh of hair but no spine, the latter practically bare. Clasper somewhat strap-like, broader before the middle, with long terminal spine (thus differing from A. fryer). Claspette with short cylindrical stem, and long, slender, curved, slightly flattened and pale appendage. Lobes of ninth tergite pro- minent, each with three or four short bristles. AEDES PSEUDONIGERIA, Theo. 1910. Monogr. Culicid, vol. 5, p. 166. The two females of this species differ from. the type in having the fifth hind tarsal segment black instead of white, but there are no other differences. Important diagnostic characters of this species are the absence of a white spot in the middle of the anterior sur- face of the mid femora, and the presence of small white spots on the under surface of the mid and hind tibiae, near but not reaching © the base. In addition to the Ovamboland material, a few specimens from the Cape Province were included. These proved of considerable scientific interest, there being no fewer than three new species represented, besides others which had not previously been recorded from the Cape. The species represented were the following: — Anopheles (Myzomyia) cinereus, Theo. Montagu (Barnard). Aedes (Finlaya) barnardi, sp.n.

Edwards, Some Mosquitos from Ovamboland, S. W. Africa. 164 This list includes two species which have been previously recorded from the Cape Province (An. cinereus and T’. longiareolata). Apart from these nine, Culex futigans has been recorded, but | am not aware of any other species which as yet are known to exist in the province. The mosquito fauna of this region is indeed less known than that of any other part of Africa, with the possible exception of Abyssinia. ANOPHELES CINEREUS, Theo. 1901. Monogr. Culicid. vol. 4, p. 164. The Cape specimens of this species differ slightly from the Rho- desian (type) form, and when more and better material is available they may possibly prove to be distinct. I think there can be scar- cely a doubt that this is the species originally described by Loew from Caffraria as A. costalis, and that Theobald’s interpretation of Loew’s species, which is now widely known as A. costalis, is incorrect. Since, however, Loew’s type appears to be lost, the confusion which a change in nomenclature would produce may perhaps be legitimately avoided. A. costalis, Theo, is not yet definitely known to occur in the Cape Province, though it quite probably does so. AEDES (FINLAYA) BARNARDI, Sp. n. Q. Head clothed mostly with rather broad, pointed, close lying pale ochreous scales. Proboscis blue-black, slender, slightly longer than the front femora.

Thorax with blackish mtegu- ment, except for the scutellum, which is ochreous. Mesonotum clothed mostly with black scales, with five straight and rather sharply marked longitudinal lines of pale ochreous; median line forked a short distance in front of the scutellum; lateral lines occupying the margins, and composed of broader scales than the others, expanding into a rather large patch in front of each wing-base. Scutellum nearly bare; a few mixed light and dark scales on the mid lobe.

Wing- scales uniformly blackish, outstanding ones lgulate; venation normal. Wing-length 45 mm. Caledon division: Oudebosch, 1500 ft. Jan. 1919. 5 QO (cotypes). The only other Ethiopian species of the subgenus Finlaya are A. longipalpis, Griinberg, A. fulgens, Edw., A. wellmani, Theo., and perhaps A. fascipalpis, Edw. The new species is very distinct from all of those in its thoracic ornamentation, but agrees in leg-markings with A. wellmani, to which it is obviously not distantly related. AEDES (ECCULEX) CAPENSIS, sp. n. Close to A. (#.) marshalli, Theo., differing as follows: — Silvery scales on anterior lateral margins of mesonotum forming a narrow line extending from almost the middle line in front to the scutal angle (in A. marshalli these scales form a shorter and broader patch) ; no white pre-apical spots on any of the femora. Caledon Division: Oudebosch, 1500 ft. Jan. 4919. 3 99 (cotypes). The specimens are in bad condition, and a full description cannot be given, but the above diagnosis will be sufficient to distinguish the species. From the nearly allied &. apicoannulatus, Edw., and A, simulans, N. & C., the new species differs in having (like 4, marshalli) a pair of small round spots in the middle of the mesonotum composed of flat silvery scales.

Cape Town, (Dawson). cj’, This species is very distinct from the other known Ethiopian species of the group (C. rima, Theo., C. rubinotus, Theo., C. kingia- nus, Edw., and C. salisburiensis, Theo.) by the characters of the proboscis, palpi and hypopygium. ( 164 ) 4, — The South African Nemestrinidae (Diptera) as represented in the South African Museum. — By M. Bezzi. Through the kindness of Dr. L. Péringuey, Director of the S. African Museum I have been able to study an interesting Collection of South African Nemestrinids on which this paper is based. The Nemestrinidae form a small family of Diptera, easily distin- euished by their very peculair venation, the most striking feature of which is the so-called ‘diagonal vein’’. There are about 160 species described from the whole World, and distributed among about 20 well established genera, mostly restricted to various zoological Regions. Only Hermoneura, Rhynchocephalus and Atriadops are seemingly represented in several regions of the Old and of the New World. ‘To these living species must be added 6 fossil ones, 3 belonging to Hermoncura, while the other 3 are ascribed to peculiar extinct genera; of these last, only one, Prohir- moneuwra Handlirsch (4906), has been found in Europe, while the other, Palembolus Scudder (1878), and Hirmoneurites Cockerell (1910) are both from Florissant, Colorado, U.S. America. Very little is known of the metamorphosis and the bionomics of these flies. No doubt they are parasitic upon other insects of various orders, as proved in the case of the European species Hermoneura obscura which attacks im an extraordinary manner the Scarabaeid beetle, Rhizotrogus solstitialis, and of the South American Hfermoneura exotica which is said to lay its eggs in the nests of Bees of the gen. Xylocopa. The adults are flower haunting flies, at least those with well developed mouth parts; and some of them are very like in their habits the Bombyliidae with which they may be confounded on super- ficial examination. The long or very long proboscis of some species is a proof of their adaptation for visiting some flowers with long, tubular perianth. Thus Westermann *) has, as far back as 1821, described *) * Ueber die Lebensweise der Insecten in Ostindien und am Cap. Germar. Mag. Entom, IV, 1821, p. 411—427. Quoted also by Macquart (1840, pl. 13) and by Lichtwardt. (1910, p. 618). M. Beazi, The South African Nemestrinidae (Diptera). 165 the behaviour of Megistorrhynchus longirostris at the Cape, towards the flowers of a Gladiolus. Professor Arias in his Monograph of the Spanish species (4913, p- 9-10) has given some details on the behaviour of Nemestrinus aniassi, whic h visits the flower-heads of the Composite plant Onopordon acanthium L., and on that of Rhynchocephalus tauscheri hovering near the flowers of the labiate plant Marrubiana vulgare, L. I have ob- served myself in 1895 in Calabria, South Italy, Tallenia fasciata on flower-heads of a species of Carduus; it was very common in June, and when sitting on the flowers, it was easily captured even by the hand; it very much resembles Bees of the gen. Podalirius. Other species seem likewise to mimic Aculeate Hymenoptera of the family Apidae, or related forms. The habits of the species with atrophied mouth parts are not known; and the same must be said of the widely spread Genus Hermoneura. Most of the species are very rare; but this is probably due to the ignorance of their mode of life; thus Hermoneura obscura, an insect which is very rare in Europe (in more than 30 years I have never captured one), was once found by Prof. Handlirsch to be abundant in its natural habitat The geographical distribution of the family is very interesting as was long ago pointed out by Osten-Sacken. Its members are denizens of warm, dry, almost rainless climates. South Africa is one of the regions in which they have found their home. It is curious to note that, while numerous species are known from Northern as well as from Southern Africa, almost none have been found to occur in the central parts of the Continent. The South African forms are peculair to the Region, and of 6 genera represented there, 4 are endemic including the very abun- dant genus Prosoeca. But the South African fauna is perhaps not well known as yet in this respect. Wiedemann, (1818-1830) enumerates only 5 species, and Macquart (1840-1846) only 4. Loew, in 1860, cotalogued and partly described as new 11 species. Schiner, in 1868, recorded 20 species, from the whole of Africa, but only the same number from the South; the main merit of this record is the important progress made in the inclusion of the South African species of Nemestrinus having no reti- culate wings into a special genus Prosoeca. The Catalogues of Bezzi (1906) and of Kertesz (1909) both include 13 species; but a serious fault of both these Catalogues is that of not having recognised in its true sense the value of the Schinerian genus Prosoeca. 166 Annals of the South African Museum. Finally, in 1910 Lichtwardt in his Monograph enumerates 23 species, --+ 2 not named, -++ one recorded by Miss Ricardo, but not deter- mined, ++ the overlooked macularis, Wiedemann, and in 1920 he added five species to the 8. African fauna. The absence of the gen. [ermoneura, which is recorded from all parts of the World is very noteworthy. Very characteristic also is the absence of the gen. Nemestrinus, which is plentiful in North Africa and in the Mediterranean region.

No ocelli, at the apex of the wing; below the first vein, there are 4 other -longitudinal veins (the 2nd, the 3rd and the two-branched 4th) all sepa- rated to the end and thus forming 5 posterior cells; 6th longitudinal vein two-branched, the lower branch valaies the exillary cell into two cells. : : . Atriadops, Wand. 9 . Ocelli present; at ies apex of the wing are 3 longitudinal veins only (the 2nd, the 3rd, and the simple 4th) below the first, thus forming only 3 or 4 posterior cells; 6th longitudinal vein simple, the axillary cell not being divided. . Diagonal vein extended to the hind border of the wing; 4 posterior cells present; 2nd longitudinal vein united by a cross vein to the first, but wholly separated from the third; discoidal cell very narrow; anal cell - open; hind border of the wings sinuous. .

Diagonal vein not extended to the hind border; 3 posterior cells only; second longitudinal vein not united by a cross vein with the first, but united with the 3rd before reaching the costa; discoidal cell broad; anal cell closed; hind border of the wings entire . Symmictus, Loew. . Proboscis and palpi well developed, the former often long or very long; antennal style triarticulate and sharply separated at base from the rather elongate third antennal joint; wings with the ambient vein complete, with the auxiliary vein distant from the first and diverging from it at end, and with 5 longitudinal veins (the 2nd, the two-branched 3rd, and the two-branched 4th) present at apex below the first and thus always with 5 posterior developed cells; diagonal vein always extended to the hind border of the wing. .

This genus has a very peculiar venation, having 2 marginal and 2 submarginal cells; the 3rd longitudinal vein is forked, but there are 3 veins only at apex below the first one, because the upper branch of the cubital fork ends in the second longitudinal vein, being shaped as a cross vein, which divides the submarginal cell into 2. The basal one of these 2 cells is much broader than the very small discoidal cell; the 2 marginal cells are formed by the cross vein uniting the 2nd with the first longitudinal vein, and the apical one is half as long as the basal one. There are only 4 posterior cells, disposed on 2 lines. The new species here recorded is a very important addition to the Ethiopian fauna, all the other species of the genus being known only from the Oriental said Australasian Regions. This new african species is not very different from the typical ones, the shape of the wings and the wing-pattern bemg very like those of N. dohrni, Wandolleck, (from Sumatra, Mafar and the Andaman Islands) and of N. harni, Lichtwardt (from Kuranda, N. Queensland). NYCTERIMYIA CAPENSIS, sp. nov. An elegant species, at once distinguished by the striking shape and pattern of the wings. M. Bezzi, The South African Nemestrinidae (Diptera). 169 Type 6, Stella Bush, Durban, Natal, January 1945. (H. W. Bell—-Marley), already named as above by Dr. Villeneuve. Oo. Length of body 9 mm.; of a wing 14 mm.; of wing spread 26 mm. Head flat, a little concave behind, about as broad as the thorax; it is reddish-brown, only the great ocellar tubercle being blackish. Eyes bare, very approximate in front of the ocelli, with the upper areolets much larger than the lower ones, which occupy only the inferior third of the eye and are sharply separated from the others. Frons elongate-triangular, gradually broadening forwards, entirely reddish-brown and clothed with reddish hairs; ocellar tubercle with darker hairs, while those of the occipital border are reddish. Face very deeply excavated in the middle with a rounded convexity of reddish colour, clothed with rather scarce and not very long, reddish hairs. Antennae very short, with the third jomt rounded and smaller than the preceding one; they are pale yellowish like the rather thick style, which is twice as long as the antenna. Thorax short and broad, distinctly broader than long; it is opaque, reddish- brown, grey-dusted, with a brown longitudinal patch on each side from the humeri to beyond the middle, and in addition with a brown spot on the postalar calli; it is clothed with rather long, soft, reddish hairs which are denser on the pleurae and scarcer in front of the scutellum; above the root of-the wings there are some dark coloured and bristle-like hairs. Scutellum swollen, rounded, dark reddish brown, clothed with long, erect, reddish hairs. Squa- mulae rudimentary; halteres whitish, with a dark reddish tuft of hairs before them. Abdomen as broad, but twice as long as the thorax; it is reddish browe, opaque, but each segment has 2 rather shining, greyish, rounded spots in the middle, one on each side; the reddish hairs are more scattered and shorter than those of the thorax; venter reddish-grey, scarcely pilose; genitalia promiment, reddish brown, with a shining lower terminal lamella. Legs very short and entirely of a pale yellowish colour; front femora thicker than the others, and more densely pilose, their hairs being moreover darker than those on the remainder of the legs. Wings narrow and long, cuneate at base, the alulae being very narrow, almost linear; they have the fore border quite straight, while at the hind border there are 3 distinct, rounded projections; one just below the tip, which is therefore curved downwards, one at the end of the diago- nal vein, and one at the end of the anal cell. The costa is bare, and ends at the tip of the 3rd longitudinal vein; the disposition of the ves is the same as in Wandolleek’s fig. 8. The whole wing 170 Annals of the South African Museum. is of an opaque reddish-brown colour, which becomes less intense towards the hind border; the fine, sharply defined, whitish-hyaline spots are shining with pearly sheen; the disposition of these spots is more like that of dohrni (Wandolleek’s fig. 7), than that of harni ‘(Lichtwardt’s fig. 41). They are as follows: (1) a spot near the base of the axillary lobe, with the upper border rounded and the outer border concave, as in horni; but while in horni it is the upper corner of the spot which is more prolonged, in capensis we have the opposite case, the lower corner being the more prolonged one; (2) an ovate spot into the middle of the second basal cell, less developed than in dorhni, but much more developed than in horni; (3) a broad, double spot, which fill up broadly the middle of the first submarginal cell and is continued above and in front by a smaller spot, near the end of the first marginal cell; the shape of this spot is about the same as in dohrni and in horni, but the spot in capensis is less transverse; (4) a broad, perpendicular streak near the base of the srd and 4th posterior cells, extended about to the hind border of the wing; this spot is eminently chatacteristic of the present species, being in dohrni and in horni indicated only by the small rounded spot near the base of the 35rd posterior cell; (5) a transverse streak near the tip of the first posterior cell in contact with the 3rd longitudinal vein; this is the second or apical one of the two corresponding streaks of dohrni and of horni, the first or basal one being quite wanting or only indicated by a small subhyaline dot which is surrounded by darker parts.

The ocelli ave very small and much apart from each other, disposed on an equilateral triangle, the anterior one being of a not larger size. Face more shining than the frons, clothed with yellowish hairs, like those of the beard. Antennae with the two basal joints red, clothed with yellowish hairs; first joint about twice as long as the second; third joint of a deep black colour, regularly conical, about as long as the two first joints together; arista of a deep black colour, as long as the whole antenna, with the basal joints well developed. Palpi reddish, narrowly black at end; proboscis intensely black, a little longer than the half of the body. Thorax and scutellum blackish-brown, grey-dusted, rather opaque; the back has two less distinct, dark reddish, longitu- dinal stripes; they are clothed with erect, rather dense, reddish yellow hairs; pleurae more densely grey-dusted, with more yellowish hairs, chiefly those of the meso-pleural tuft. Squamulae and halteres pale yellowish. Abdomen reddish brown towards the sides and the hind border of the segments, brownish on the middle, with a shining black longitudinal stripe which is however less marked; it is clothed with rather short yellow hairs, which on the sides are of a golden colour; venter reddish-yellow; ovipositor blackish brown, with black terminal lamellae. Legs entirely reddish, rather shining, with scarce, pale yellowish hairs. Wings about as long as the body and thus much shorter than those of the two preceding species; they are therefore less distinctly stalked at base, the alulae being however exceedingly narrow; they are uniformly and faintly infuscated, being yellowish along the fore border from the base to the end of the costal cell. The veins are reddish basally, and infuscated apically. The venation is normal for the genus; the basal stalk of the 4th posterior cell is as long as the apical cross vein of the 2nd basal cell; the axillary vein is very short but strong, bent at an angle in the middle and directed towards the hind border of the wing.

A characteristic species of great size, and with a very long pro- boscis; at once distinguished from all the other here recorded on account of the cross vein uniting the upper branch. of the cubital fork with the second longitudinal vein, as in the gen. Nemestrinus. Type Q, from Namaqualand, Klipfontem, Cape Colony, August 1890. Rk. M. Lightfoot. The connection between the 2nd and the 3rd longi- tudinal vein in the present species, is in opposition to the main distinguishing character of the two genera Nemestrinus and Prosoeca ; but the present species is undoubtedly to be referred to the latter genus, owing to its general appearance, etc.; the cross vein is besides very short and perpendicular, (much shorter than the basal part of the upper branch of the cubital fork), not long and oblique as in Nemestrinus, in which it is always longer than the basal segment of the upper branch of the cubital fork. ©. Length of body 46 mm.; of a wing 20 mm.; of the proboscis 34 mm.; of the wing spread 46 mm. Wholly of a dark reddish-brown colour, but blackish on the back of the mesonotum, and with a dense grey dust on the abdomen. Frons with parallel sides, but a little broadening forwardly; it is less than half of the width of one eye, and is distinctly longer than broad; it has on the fore half a broad, prominent, rounded tubercle, which is blackish in colour while the rest of the frons is reddish; the frons is thus deeply depressed between this tubercle and the large ocellar one; the long and erect hairs of the ocellar tubercle are dark, like the short ones of the occipital border; the short and scarce hairs of the frons are whitish. Antennae with the two basal jomts of the same length and reddish, the second with long black hairs which are more numerous beneath, third joint regularly conical, as long as the first two jomts together, blackish in colour; style three-jointed, blackish, once and a half as long at the whole antenna. Face very convex along the middle line, separated from the frons by a furrow which extends between the antennae; it is about as long as the frons, reddish, with the upper part blackish; it is clothed with short white hairs, which are denser on the sides, turning to a 176 Annals of the South African Museum. fine white beard; the hairs of the lower part of the occiput are white, but there is a complete crown of black ciliae along the border even unberneath. Palpi black, obtuse and black-haired at end; pro- boscis thin and very long, acute at end, black, with reddish base beneath. Back of mesonotum grey-dusted, adorned with two rather narrow but sharply defined deep black stripes which are slightly ' converging backwards and end acutely at the transverse suture; beyond the suture there is a less defined and short, broader brown stripe in continuation; the sides, humeri and postalar calli are reddish, and inward of the red sides there is a less defined dark stripe on each side. Pleurae reddish, grey-dusted and black-spotted below. The erect hairs of the back are black, but below them there is a shorter whitish pubescence; on the sides and on the pleurae the whitish hairs prevail, with some scattered and longer black ones intermingled; along the notopleural line, there is a dense fringe of whitish hairs. Scutellum reddish, with black erect hairs; its hind border is black, and bears longer and more rigid black hairs; the hairs of the underside are whitish. Squamulae brown, with dense, long, soft, white fringe, like the metapleural tuft; halteres with reddish stalk and with a dark knob. Abdomen with a middle row of three well defined, oblong, blackish-brown spots; each segment bears moreover on each side an irregular reticulate dark pattern ; the venter is paler and unspotted; the scattered, erect hairs are black like the short pubescence of the back; on the sides and the venter the white hairs are prevalent. The three basal segments of the tail bear also the blackish middle spot; the terminal lamellae are black and black-haired. Legs reddish brown, with darker tibiae and tarsi, those of the hind pair being even black and rater thickened ; the long hairs of the femora and tibiae are black, while the soft hairs below the femora are white; the dense and short pubescence of the tibiae and tarsi is black; breast and coxae with dense white hairs; claws red, with black tip; pulvilli yellowish. Wings narrow and long, with narrow but well developed alulae; the extreme base of the wing is blackish brown, the white basal tuft being therefore very conspicuous; the veins are reddish-brown, blackened towards the end; the second longitudinal vein and the upper branch of the cubital fork are strongly curved up at end and are parallel, while the end of the other veins are less upturned, even if distinctly so; first posterior cell considerably narrowed at end; fourth posterior cell with a sessile but punctiform base. The right wing of the type is anomalous, showing a second cross vein uniting the upper branch of the cubital fork with the second longitudinal vein, and having M. Bezzi, The South African Nemestrinidae (Diptera). al7i7l moreover a supernumerary cell of oval shape before the middle of the upper branch of the cubital fork. The brown pattern is very marked, consisting in a broad fore border extending about to the middle of the wing, the end of the first submarginal cell being however hyaline and fenestra-like; there is moreover abroad, isolated, brown spot below the discoidal cell filling up the apex of the second basal and the base of the fourth and of the fifth posterior cells; and another spot before the end of the diagonal vein, fillmg up the base of the second and the apex of the fourth posterior cell, extending a little above and below them. The alula has the hind border hyaline near the end; the discoidal cell, is almost entirely hyaline, while the first basal cell is quite infuscated to the end; the second basal cell is broadly hyaline at end; the second submarginal cell is entirely infuscated, while the third is almost entirely hyaline in the middle; the first posterior cell, and the second, more narrowly, are infus- cated at end forming the apical limit of the fuscous fore border of the wing.

PROSOECA LONGIPENNIS, Loew. 1858. A species of great size, described from the Cape, and captured several times in South Africa. One © example from the Cape; also identified as such by Licht- wardt (1920). PROSOECA ROBUSTA, Sp. Nov.

The true caffrauria has not been seen by me. It is described as coming from the Transvaal. Recorded also from Barberton, New Agatha, Lemana, Woodbush Ville. (P. zuluensis is a close ally of, if not identical with cafraria, Editor). ProsoEcA UMBRosA, Lichtwardt 1910, Closely allied to the preceding species, but distinct by the more lightly coloured body and wings. Originally described from Natal, East London, Cape, (EK. Borcherds) Howick, (Cregose) Durban, Karkloof, Natal, May 1915 (H. W. Bell- Marley). Frons and face entirely reddish, like the antennae and the legs, which have not infuscated tarsi; the ciliae of the second antennal jot are yellowish. Scutellum reddish brown. Abdomen distinctly reddish above on the sides of the segments. Wing-veins entirely reddish-yellow; wing-base reddish-brown; base of fourth posterior cell punctiform. Prosorca ATRA, Macquart 1846. Originally described from the Cape as a Hermoneura and placed in the present genus by Lichtwardt in 1910; it seems to be closely allied to the species described here for the first time under the name of connexa. I have examined the example named by Lichtwardt. PROSOECA LICHTWARDTI, Nn. sp. Closely allied to handlirschi Lichtw., but at once distinguished by the entirely red legs. Type Q, a single specimen from Paarl, Cape. October 1888 (R. M. Lightfoot). This is the same specimen recorded by Lichtwardt without a name (1920, p. 100, No. 127), as being intermediate between hand- lirschi and westermanni. It is now described as new, and named in honour of the Mono- grapher of the Nemestrinidae, whose studies have greatly contri- buted to the progress of our knowledge of these interesting flies. Q. Length of body 12 mm.; of wing 15 mm.; of wing spread 26 mm. Frons black, grey-dusted, a little narrowed towards the middle; it is clothed with long dark erect hairs on the ocellar tubercle, and with more short but dense and bent forwards, whitish ones on the frontal half. Occiput grey-dusted, with thin whitish 186 Annals of the South African Museum. hairs at border. Face convex, densely clothed with whitish hairs, like those of the anterior part of the frons; beard whitish. Anten- nae entirely black, the second basal joint grey-dusted and clothed with long pale yellowish hairs; third joint elongate, conical, as long as the two first joints together: arista deep black as long as the whole antenna, with the two basal joints of equal length. Palpi reddish, with long yellow hairs; proboscis black, short and stout, as long as the vertical diameter of the head. Thorax entirely clothed with pale yellowish hairs, which are short on back and longer on the pleurae; on the back it is black, with two narrow but complete whitish longitudinal stripes in the middle; on the sides, in contact with the notopleural bare line, there is a broader whitish stripe, on which are several black hairs. Pleurae densely grey-dusted. Scu- tellum black, grey-dusted, with long yellow hairs at hind border. Squamulae and halteres blackish. Abdomen shining black, the hind border of each segment with an opaque dark grey transverse band, which is broader in the middle, chiefly on the last segments, moreo- ver there is in the middle of each segment a triangular opaque spot, with the base at hind border; the hairs are black on the back of the tergites, yellowish on the side and on a transverse band a base; venter densely grey-dusted, with pale hairs. Legs entirely reddish with very short reddish pubescence. Wings greyish-hyaline, a little infuscated along the fore border and with the first basal cell; vein reddish-yellow, those of apex curved up at end; tuft at root white. Stalk of cubital fork rather long; base of fourth posterior cell not punctiform; anal cell narrowed at end; alulae rather broad. PROSOECA CIRCUMDATA, Lichtwardt 1910. This species is at once distinguished from the two preceding ones by its hairy frons and its moderately shiming abdomen. Originally described from Natal. Durban, Natal, February 1914 (W. Haygarth); Transvaal, Woodbush (Leigh). Frons clothed with long, erect, whitish hairs; ocellar tubercle black and black-haired. Basal joints of the antennae with whitish ciliae; the two basal joints of the style are short, measuring together a third only of the length of the terminal jomt. Proboscis black above.

A robust species with a very short and stout proboscis, eminently characterised by the shining black, grey-banded abdomen, and by the entirely black legs. Originally described from Robinson’s Pass; there is a female specimen, likewise from a mountainous distinct, Gt. Winterhoek, 5000 ft., Tulbagh, April 1916 (R. M. Lightfoot); Hottentots Holland Mountains, 4000 ft. (K. H. Barnard); Caledon, Cape (L. Péringuey). Proboscis entirely black, even above at base; second joint of the style longer than the first, both measuring together more than one half of the rest. Scutellum with gold-yellow hairs like the meta- pleural tufts. Claws black, with a red base; pulvilli and empodium yellowish. Stalk of the cubital fork long; base of the fourth poste- rior cell not punctiform. PROSOECA QUINQUE, Lichtwardt 1920. I have seen the type of Lichtwardt; the species seems to be not easily distinguishable from variegata Loew. PROSOECA VARIEGATA, Loew 1858. Described from the Cape and recorded from South Africa by Lichtwardt. PROSOECA ORNATA, Lichtwardt 1910. Originally described from Simon’s Town, Cape. I refer with doubt to it a not well preserved male example from Grahamstown Cape, in my collection. This specimen shows the venation characters of the species, but has a less developed general pattern of the body. PROSOECA VARIABILIS, Loew 1858. Distinct by the non spotted wings, which have moreover quite straight veins at apex. Originally described from Caffraria; is possibly the female of fusca, Loew. There is a female specimen from Durban, Natal, February 1914 (W. Haygarth), answering very well to Loew’s description. The stalk of the cubital fork is long; the fourth posterior cell is puncti- form at base; the alula is very narrow; the basal tuft is white. ProsoEca FuscaA, Loew, 1860. Known from various localities in Natal, and described originally from “Caffraria”. A doubtful miniature female example from Cape Town, is referred to this species. 188 Annals of the South African Museum. ProsoEca accincTa, Wiedemann 1830. Originally described from the Cape, and recorded subsequently from Natal. I have seen one male from Barberton, Transvaal, deter- mined by Lichtwardt. PROSOECA CONNEXA, Sp. Nov. A black and black-haired species with spotted wings, easily dis- tinguishable from all the others on account of the black basal tuft of the wings, and of the united branches of the fourth longitudinal vein. Type o', a single specimen from Durban, Natal, February 1914 (W. HayGartH). Occurs also in the Transvaal. Woodbush. It is very near accincta, being possibly only a variety of it; but it is much blacker and black-haired, thus answering probably to atra. o. Length of body 12 mm.; of proboscis 40 mm.; of a wing 43 mm.; of wing-spread 32 mm. Frons black, grey-dusted, rather nar- rowed before the front ocellus; it is clothed with long, dense and erect black hairs, those of the anterior part being developed like those of the ocellar tubercle. Occiput hollowed, black, grey-dusted below, with short black hairs at the border. Face convex, reddish, with long black hairs on the sides; beard yellowish. The two basal jointe of the antennae are reddish-yellow, the first being longer than the second, which has very long black cilia above and below; third joint deep black, narrowly conical, as long as the first two Joints together; style black, a little longer than the whole antenna, with the basal two jomts of equal length. Palpi reddish, with black tip and with black cilia at end; proboscis a little shorter than the body, red above at base, black on the apical half and below. Thorax and scutellum of a deep, velvety black colour and opaque; they are clothed with long and dense black hairs; the pleurae are grey-dusted and black-haired, even the subalar and metapleural tufts being black. Halteres black. The abdomen in the middle is coloured like the thorax, while on the sides it is rather broadly reddish brown; the hairs are black, pale yellowish on the sides of the first segment, but not forming the yellowish band of accincta. Venter more lightly reddish, grey-dusted, with yellowish pubescence; genitalia reddish brown behind and below, dark-haired. Legs entirely reddish on the femora, more pale yellowish on the tibiae and on the tarsi, the last tarsal jot only. being darkened; the long hairs of the femora are black, while the short pubescence of the tibiae is yellowish; claws black, with red base; pulvilli and empodium dirty yellowish. Wings infuscated on the fore half, greyish hyaline on the hind one, but M. Bezzi, The South African Nemestrinidae (Diptera). 189 the limit is not sharply defined; there are besides some diffuse fuscous spots at the end of the second basal cell and at the base of the fourth posterior cell (round its punctiform base), at the end of the first basal cell and at the base of the cubital fork. The veins are black, only the aixillary one and the first bemg dark reddish; the extreme base is black, with a black tuft. All the longitudinal veins are quite straight at end; the stalk of the cubital fork is long; first posterior cell irregularly shaped; second posterior cell divided into three cells by two supernumerary cross veins placed near its middle and forming thus a small trapezoidal cell between them; base of the fourth posterior cell punctiform; anal cell narrowed at end. Alula very narrow. Possibly an aberrant example of atra Macq. MEGISTORRHYNCHUs, Macquart, 1840. In the present genus are comprised the more highly specialised species of the South African Nemestrinidae, with a remarkable net- work on the apical half of the wings, and with an often exceedingly long proboscis. The two known species may be distinguished as follows: (2) 1. Proboscis as long as the body or nearly so; lower branch of the anal vein not appendiculated in the middle, or with a very short appendage outwardly : : . brevirostris, Wied. (1) 2. Proboscis many Lines ences than An body; lower anal branch with a long appendage in the middle, placed inwardly . longirostis, Wied. MEGISTORRHYNCHUS BREVIROSTRIS, Wiedemann, 18214.

Winterhoek, Tulbagh, Cape, 4500 ft., November 1914. (R. M. Lightfoot). The grey spots of the abdomen are isolated as in lonyirostris, The stalk of the cubital fork is short; the fourth posterior cell is broadly sessile at base; the anal cell is nearly closed at the wing border; the alula is rather broad, being a little more than twice longer than broad at end; the basal tuft at root of wing is white.

The species of the family Mydaidae can at once be distinguished by the shape of the antennae, and the peculiar venation of the wings. They cannot be confounded with any other South African Diptera; their greatest affinity is with the Nemestrinidae and with the Apio- ceridae. But the species of the former are very different in the short, broad and villose body, in the short antennae, and in the more numerous veins free at end in the apical part of the wings. And those of the latter, of which only one South African species, Ripido- syrma alastor, Walker 1849 = braunsi, Melander 1907 discovered at Willowmore (Cape) by Dr. H. Brauns is hitherto known, are at once distinguishable by the strong macrochaetae on the sides of the back of the mesonotum, and by the very different antennae. A super- ficial resemblance in the shape of the head and of the elongate body with the Asilidae is no doubt deceptive to an inexperienced eye; but even in this case the shape of the antennae, the absence of macrochaetae and the neuration of the wings are sufficient for an easy identification. 7 A peculiar and very conspicuous feature of the Mydaidae, is the presence of two prominent callosities or bullae at the sides of the hind border of the second abdominal segment; these bullae are equally developed in both sexes and have a different colouration from that of the surronnding parts; they are often described by the authors as an interruption of yellowish or whitish hind border of the second segment of the abdomen. The family of the Mydaidae is not a numerous one, only 140 species distributed among 16 genera, are at present known. Moreover the species are of the greatest rarity among the Diptera, being but poorly represented in collections, and usually only by single specimens; no long series have been obtained, and therefore we have no idea of the variability of the species. They are repre- sented chiefly in South America and Australia, being very scarce in the Oriental Region. In Africa they seem to occur chiefly along the 4:92 Annals of the South African Museum. Mediterranean region and in the South, and are almost entirely absent from Central Africa. But the number of African species is quite small, in the old Monographs of Wiedemann and Westwood only a few are included. Loew in his work on South African Diptera describes only 4 species of Cephalocera; Gerstaecker in his Monograph has added a few. The total mumber of the known Ethiopian species is at present 17. In recent times no new species have been described from South Africa, except those published by Gerstaecker in 1868. Very little is known of the habits of the adults. Old writers have stated that they are predaceous, and this was stated afresh recently by Prof. Arias; but it seems that they are flower-visitors. It must be remembered that some species have the mouth parts atrophied, while others have them elongated and slender. The known larvae live in wood and live probably on wood-boring larvae of Coleoptera. Some South American species are the largest of all the living Diptera ; but the South African ones are only of medium size, and have as a rule an elongate body of Asilid appearance. The following is the more important literature on the family. WIEDEMANN, C. R. W. Monographia generis Midarum. Nov. Act. Acad. Nat. Curioa., XV, 1831, p. 19-56, 3 pl. Macquart, M.

The South African genera of Mydaidae, with the addition of four new ones, can be distinguished as follows. All have the circlet of spines at the end of the female abdomen, and in all the palpi are hardly visible. It is not at all impropable that species of the gen. Mydas will be found in Africa, as they are present in the Oriental Region; they can be recognised by the non spinose ovipositor, by the well developed palps and by the presence of the hind marginal cross-vein on the wings. In all the genera here enumerated both branches of the cubital fork (R4 & R45) end into the first longi- tudinal vein (R11); the North African genera Rhopalia and Perisso- cerus, Which have the lower branch of the cubital fork (R5) ending into the costa, may perhaps be found to occur in South Africa. Key to the Genera. (2) 1. Hind margin of the wings in the middle with a cross vein, which is the end of the upper branch of the fifth longitudinal vein (M, + M,); * both branches of the cubital fork (R, and R,) ending into the first vein (Ry), but the fourth vein (M,_.) ending free in the costa; terminal cross-veln of the third posterior cell** about as long as that of the * This M, is the Cu, of the Comstock-Needham System; but according to the recent investigations of Dr. Tillyard, the Cubitus is a strong straight unbranched vein in the Diptera, as it is also in their ancestral forms, the Mecoptera.

No hind-marginal cross-vein, the upper branch of the fifth vein ending into the fourth vein; terminal cross-vein of the third posterior cell usually much shorter than that of the discoidal cell; 2—3 terminal segments of the female abdomen with a peculiar pubescence directed forwards; hind tibiae without terminal spine, or with a very small one. Fourth long vein (M,_ 2) ending free into the costa, at some distance from the terminal stalk of the second submarginal cell, the first posterior cell being therefore broadly open at end.

This is a typical South-African genus, very distinct from all the other on account of the presence of a hind-marginal cross-vein in the wings, and of the strong spine at the end of the posterior tibiae. M. Bezzi, The South African Mydaidae (Diptera). 195 These characters are those of a neotropical true Mydas; but it differs clearly from that genus in the presence of the circlet of spines at end of the ovipositor. The body is shorter and thicker than in all the other South- African genera, Haplomydas excepted; it is bare or nearly so, and the teguments are smooth; the callosity before the halteres is always bare; the legs are bare. The anterior ocellus is well developed. The proboscis is rudimentary or very short, not projecting. The third antennal joint is long, being longer or as long as the terminal club. The hind femora are thickened and spinose beneath, at least in the male; the spines are placed in 2-4 rows. The male genitalia are small and not free. The wings are as long as the abdomen or nearly so, and have a rather thick ambient vein. The upper branch of the cubital fork (R 4) is appendiculed at the base. The discoidal cell is always acute outwardly, its contact with the second posterior cell being always punctiform. Third posterior cell broader at end than at base, its terminal cross-vein being about as long as that of the discoidal cell. Third posterior cell not placed on the same line as the first, The genus Ketyphus may be considered up to the present as monotypic. The two North American specimens described by Willi- ston belong in all probability to a peculiar genus, as indicated by the different male genitalia; limbatus 1886 has a terminal spur of the hind tibiae in the male but not in the female, and likewise towsendi 1897 as stated by Cresson in 1907. In the collection of the South African Museum there are 3 species, which may be distinguished as follows: (2) 1. Halteres pale yellowish; face golden yellow; abdomen with rather broad yellow bands; male with thickened hind femora and spurred hind tibiae. female with slender hind femora and not spurred hind tibiae, which bear 3 equally distinct bristles on the posterior side. pinguis, Gerst.

(Father J. O. Neil). One female in my collection from Klememond, Grahamstown, (Cape) January 1897, (Miss White). The female is much larger than the male; the yellow bands of the abdomen may be interrupted in the middle, like those of the male. The bullae of the second abdominal segment are narrow, nearly linear, and blackish. EcTYPHUS ARMIPES, sp. nov. A robust species, allied to the preceding one, but distinct by the darker colour of the body, antennae and legs, and by the strong terminal spur of the hind tibiae in both sexes. Type co and type Q; Stellabush, Durban (Natal), H. W. Bell— Marley, January 1915. o Q. Length of the body 15-16 mm.; of the wing 13-14 mm. The male is much darker than the female and has black femora. Head entirely black in the male, with grey dust near the border of the eyes on the occiput, clothed. with whitish hairs on frons and face, those of the latter being longer. Head of the female reddish, with a black median stripe on the frons, and clothed with yellowish hairs. Antennae of the male black, with the third joint reddish; those of the female reddish, with infuscated basal joint and terminal club; in both the first joint is twice as long as the very short second, and the third is more than twice longer than the two basal joints together; the club is a little shorter than the third joint, broad, swollen, ovate. Proboscis not longer than the mouth opening, but well developed, with broad termlnal flaps. Thorax of the male entirely black, opaque, with reddish humeri and with a reddish stripe above the notopleural line extended to the postalar calluses; pleurae entirely black; rather shining, bare, with some white hairs on the pteropleura alone; on the back there is a sparse whitish pubescence, arranged in two broad longitudinal stripes; scutellum entirely black, with spare whitish hairs.

In the female example the upper branch of the cubital fork is broadly interrupted at the base, its basal portion with the appendix being altogether wanting. EcTYPHUS ABDOMINALIS, sp. nov. Q. Easily recognisable in the female sex by the darker legs, the non spurred hind tibiae and the black abdomen, which has a red longi- tudinal stripe along the middle. From both the preceding, species it is distinguished in the more regular shape of the lower branch of the cubital fork, running parallel with the fourth vein along its whole course. Type Q a single specimen from Montagu, Cape Col., January 1876. (R. Trimen). Q. Length of the body 15 mm., of the wing 12 mm. Head black, clothed with dark grey dust. but the face is reddish with whitish dust. Occiput with sparse reddish hairs near the middle and above near the eyes, which are edged with a grey stripe. Frons densely grey-dusted, with dark reddish hairs; face with pale yel- lowish hairs, which are whitish near the mouth. Antennae black, with the third joimt dark reddish on its basal half and twice as long as the first two jomts together; terminal club blackened, a little shorter than the third joimt. Proboscis shorter than the mouth, black, with broad terminal flaps. Thorax entirely black, only the humeri and the postalar cells being dark reddish; on the back it is opaque, dark grey-dusted, with short dark pubescence; pleurae shining, reddish-brown along the sutures, bare, except a few short hairs on the pteropleura. Scutellum black, pubescent and dusted like the back; mesophragma black, reddish-brown on sides; squamae dark yellowish, with short whitish fringe; halteres blackish.

Wings ereyish-hyaline with the veins edged with fuscous, only the costal and basal cells and base of the marginal cell being entirely infus- cated, but with clear stripes in the middle. The second submarginal cell is of a regular shape, being about as broad in the middle as at. end, the lower branch of the cubital fork being regularly and gently curved and quite parallel with the fourth vein; the first posterior cell is as broad in the middle as at end; the discoidal cell is stalked at end. Axillary lobe and alula edged with fuscous, the latter more broadly, and with a short but distinct dark fringe. Third posterior cell with punctiform base. HAPLOMYDAS, gen. nov. Nervuration of the wings as in Leptomydas, lacking a hind-mar- ginal crossvein and with free end of the fourth longitudinal vein; but the upper branch of the cubital fork not appendiculated at base. Moreover the anal vein is straight, being suddenly curved below near the end; the ambient vein is very thin, almost iridescent. The lower veins of the first and of the third posterior cells are not placed on the same line. The terminal cross-vein of the first basal cell is separated from the terminal cross-vein of the discoidal cell, meeting with it and with the third longitudinal vein nearly at the same point; in other words the discal cross vein is reduced to a short stripe or only a simple dot, but this may be due to some anomaly of the unique type specimen. Head as in Leptomydas, but with the frons less hollowed at ver- tex; anterior occellus well developed; eyes bare. Third antennal joint shorter than in Leptomydas; proboscis very short, not projecting beyond the mouth opening, but well formed, with broad terminal flaps. Palpi not distinct. Body nearly bare, the metapleurae with a few scattered short hairs; the teguments are smooth, with no sculpture on thorax, and with a few scattered, impressed points on the abdomen, this last is broad at base, not pedunculate. Legs bare, proportionally short and stout; hind coxae greatly swollen; hind femora very much thickened, club-shaped, and armed below with four rows of strong spines; hind tibiae much arched at base, and with a small, acute spur internally at end. The segment of the ovipositor bearing the circlet of spines is exserted, not concealed as in Leptomydas, Type: The following new species. From Rhopalia and Perissocerus, which have a non appendiculated second submarginal cell, the present genus is distinguished, also from 200 Annals of the South African Museum. Syllegomydas, by the very different neuration of the tip of the wing. From Eremomydas, with which it agrees in the veins of the tip of the wing and in the shortness of the proboscis, it is distinguished by the non appendiculated second submarginal cell, and by the second longitudinal vein ending into the first far from the end of the upper branch of the cubital fork. TTAPLOMYDAS CRASSIPES, Sp. Nov. A small, bare species, at once distinguished by its generic characters. Type Q; aunique specimen from S. Rhodesia, Bulawayo, May 1917, (R. W. Tucker.) Q. Length of body 12 mm.; with the antennae 13.8 mm.; of wing 9 mm. Head black, but yellowish on the face, very shiny along the middle line, densely clothed with whitish dust on sides of frons. It is clothed with rather short, not bushy, white hairs; the dark postvertical bristles are short but strong. Antennae proportio- nately short, about as long as the transverse diameter of the head; they are dull reddish-brown, with the terminal club brighter reddish ; the first jomt is twice as long as the short second joint; the third joint is less than twice longer than the two basal joints together, its terminal portion being nearly as long as the first jomt *); terminal club swollen, ovate, as long as the third joint, with a distinct, rather long, truncate protuberance at end. Proboscis reddish-brown, with black flaps. Back of thorax dull. black, with reddish-yellow humeri and postalar calli; it is almost bare, and has four longitudinal stripes of whitish dust, placed at equal distance, the exterior ones in contact with the notopleural line, and these beset with short scattered hairs. Pleurae shining black, bare, the pteropleurae reddish- yellow, the metapleurae with very short pale hairs. Scutellum and mesophragma black, dark grey-dusted, bare; squamae and halteres pale yellowish. Abdomen shining black, even on venter, only the terminal segment dark reddish-brown; all the segments have a broad yellowish hind border, which is even broader on the venter; bullae minute & whitish, rather iridescent. The abdomen is bare, even the whitish hairs of the sides at base bemg very sparse and short; but the two terminal segments are clothed with a rather long and dense yellowish pubescence, directed forwardly. The exserted terminal segment of the ovipositor is rounded, reddish, with dark reddish spines. The surface of the abdominal tergites shows scattered im- * This terminal portion of the third anternal joint is in reality a fourth joint, followed as a fifth joint by the so-called club, considered as the clubbed style. M. Bezzi, The South African Mydaidae (Diptera). 201 pressed points. Legs with the coxae entirely yellowish, clothed with very scarce yellowish hairs; the spies of the hind femora are black or dark brownish; the hind tibiae are bare, and destitute of bristles on hind side; claws with yellowish base and black tips; pulvilli yellowish; hind coxae with a broad, soft, opaque area in front. Wings greyish-hyaline, but they appear a little infuscated on account of the wrinkled membrane. The veins are reddish; second longi- tudinal vein straight; second submarginal cell regular, its terminal stalk about as long as the basal one; first posterior cell broadly open; terminal cross vein of the discoidal cell as long as the basal one and perfectly parallel with it; third posterior cell much broader than the discoidal cell, buth with a punctiform end; the lower veins of the first and of the third posterior cells are rather distant from the hind border of the wing. Anal cell of peculiar form; its extreme end being suddenly bent downwards, its point being short and pro- vided with a long stalk; the axillary lobe is therefore of trapezoidal tes) shape; alula rounded, rather small, not fringed. Gren. LEPTOMYDAS, Gerstaecker, 1868. This genus includes the greater number of species belonging to the South African fauna; but it is not peculiar to South Africa, having a very wide distribution in Mediterranean countries, the Oriental region and even North America. But it contains evidently heterogenous elements. Thus ZL. indianus, Brunetti, 1912, is described as having a short proboscis. The nearctic species, judging from one example of pantherinus Gerst. in my collection, are not congeneric with the Old World kinds; the above named species has indeed a short proboscis, not thickened, and almost unarmed hind femora, and the fourth longi- tudinal vein ending into the first, as already noted by Osten-Sacken, and shown in the maginficent figure given by Cole, Proc. Calif. Acad. Sci. (4), 1X, 1919, pl. 15, fig. 40; but it cannot be a Syllego- mydas on account of the long antennae and of the well developed, even if short proboscis. The other species show more differentiated characters, having long or short proboscis, open or closed first posterior cell, and appendiculated or not appendiculated upper branch of the cubital fork. All the South African species here enumerated are typical, and agree in the following characters. They have all a narrow and elongate body, which is sometimes rather villose, and have a non- stalked abdomen, which is broader at base than in the middle; the 202 Annals of the South African Museum. teguments are smooth, not sculptured. The metapleurae are hairy. The anterior ocellus is sometimes distinct, chiefly in the female. The third joint of the antennae is long; it is obviously divided in two parts, which however are not always easily seen; the terminal club is broad and long. Wings proportionately short, always shorter than the elongate abdomen. The ambient vein is thinner than in Ectyphus, sometimes hardly visible, and there is no hind-marginal cross vein. Both branches of the cubital fork end into the first longitudinal vein, the upper one always appendiculated at base; second submarginal cell always stalked at end; discoidal cell always acute at end and as a rule stalked. Fourth longitudinal vein ending free into the costa, at some distance from the end of the first; first posterior cell therefore always broadly open as in Ectyphus. First and third posterior cells placed at equal distance from the hind border of the wing, their lower veins running on the same line, parallel with the hind border self; the third posterior cell, in opposition to what is observed in Ectyphus, is narrowed at end, being there as narrow as at base; its terminal cross vein is there- fore much shorter than that of the discoidal cell, and sometimes even punctiform. The type of the genus was established by Coquil- lett in 1910: Mydas lusitanicus, Meigen. 1820. The two South-African species, westermanni and rufithorax, placed in the genus Cephalecera by the authors, are to be referred to the present genus, the numerous species of which can be distinguished as follows: — (2) 1.

The hairs are white, and rather long but not dense at the sides of the two basal segments in the male, and very short on the remainder; in the female the abdomen is practically bare, the first segment only having very short white hairs on the sides, the two terminal segments are in the female completely clothed with equal, rather long blackish hairs directed forewards. Male genitalia reddish-brown, pale-haired, with the middle upper lamella deeply emarginate at end, the upper lateral lamellae acute and triangular, and with the lateral horn-like appendages flat, shining black on the apical half; the lower lamella is rounded.

Group 11: WESTERMANNI. This is evidently a group characteristic of the South African fauna, but not easy to define in a few words if one has before him nume- rous examples of the genus. Those of the present group are at once recognisable by the proportionately broader, shorter and more hairy body; an examination of Pl. 4 IV. of Wiedemann’s Monograph, comparing figs. 45 and 16 with the others, is sufficient to give a good idea of the group. The two species westermanni and rufithorux have been placed in the genus Cephalocera by Guérin-Meneville, Westwood and _ subse- quent writers; but erroneously, as even Wiedemann’s figures show clearly the neuration of Leptomydas; Gerstaecker had no specimen for examination. LEPTOMYDAS WESTERMANNI, Wiedemann 1819. At once distinguished in the male from all the other species on account of its black and black-haired abdomen, except at base. One o specimen from the Cape, without precise locality, labelled by Bigot Cephalocera iongiventris, a name which has never been published, The species was described in a recognisable manner and subse- quently figured by Wiedeman, more than a century ago. Antennae long, with the third joint three times as long as the first two joints together, and much longer than the terminal club. Proboscis entirely shining black, with broad terminal labella, 25 mm. long. Face enti- rely black. Meso- and sternopleurae bare, pteropleurae villose, meta- pleurae with a tuft of dense long hairs. Squamae brownish. bare; halteres dark yellowish. Abdomen reddish-brown on sides and at end; male genitalia reddish, with the upper lamella slightly emar- ginate at end, and the horn-like appendages shining reddish, curved above. Venter entirely reddish, clothed with long pale hairs on its whole length, those of the two terminal segments being blackish.

LEPTOMYDAS RUFITHORAX, Wiedemann, 1821. Allied to the preceding species, but distinct in the less thick body and in the different clothing of the abdomen. Three specimens from Cape Town: one male, February 1915 (R. M. Lightfoot); another © (J. C. BriDWELL); one female without data. The male is very like that of westermanni, but the hind tibiae are less villose internally, the villosity being scattered and shorter than the width of the tibiae. The female has the abdomen longer, and is less villose than the male. Occiput with some bristly hairs above between the fur. Face yellow, proboscis reddish below; antenmal club reddish, with a blackish oval spot underneath at end. Abdomen shining black, the two basal segments with long pale hairs; the segments 2-5 with broad yellow hind border, that of the second with shining black bullae; 7-8 segment reddish, with the peculiar pale hairs directed forwards; spines of the ovipositor reddish; venter reddish-yellow, with scattered pale hairs even on the terminal ster- nites. Hind femora less thickened than in the male but equally spinose below; hind tibiae with two irregular rows of strong reddish bristles on the outer side. In the specimen at hand the legs are entirely reddish, only the four anterior coxae being black; the femora lacks the dark markings mentioned by Wiedemann. LEPTOMYDAS LANIPES, sp. nov. Closely allied to the preceding, but differing in the male by the much more villose hind legs. Type o, a single specimen from Triangle (Cape), January 1885 (L, Péringuey). oO.

Wings hyaline, with a faint but distinct diffused yellowish patch in the middle. Veins entirely reddish ; second submarginal cell regular, with a short stalk; first posterior cell broadly open; third posterior cell as broad at base as at end; the two lower veins of the first and of the third posterior cell at equal distance from the hind border of the wing, Group III: HUMERALIS. This group is the more numerous in South Africa, and the species are more diffleult to distinguish. They are recognisable by their thin and elongate body, the abdomen of the male being attenuated and less hairy in the apical half; the abdomen of the female is thicker but always elongate and nearly bare. The hind femora are less thickened in both sexes, but are always spose beneath. Besides the species recorded in the table, it is probable that dispar, Loew belongs to the present group; it is described from Mozambique as being in both sexes of a yellowish colour, with black stripes on thorax and black transverse bands on abdomen.

Antennae long, quite black in both sexes; pro- portion of the length of the joints as in the species of the preceding group. Anterior ocellus well developed in the female. Proboscis shining black, as long as the antennae, with broad terminal flaps. Thorax on the back shining black, not striped, entirely clothed with equal white hairs which are tuft-like on the sides and are not much longer in the male. Pleurae shining black, bare in the middle and below, with dense white tufts on ptero- and metapleurae; the roun- ded prominence above the front coxae is whitish-dusted and is clothed with a tuft of long white hairs. Scutellum and mesophragma shining black, the former bare, the latter with long white hairs on the sides; squamae dirty brownish; halteres blackish. Abdomen elongate cylin- drical, attenuated behind, that of the female being not much thicker than in that of the male; it is in both sexes entirely shiniug black, but the venter is reddish in the female and has red. spots in the middle segments in the male; the tergites 2-6 have yellowish rings at the hind border, broader in the female, and that of the second segment broadly interrupted in both sexes by the large, shining black bullae. All the hairs of the abdomen are white, being dense and long on the two basal segments chiefly in the male; the 4-5 ter- minal segments have in the female the peculiar pubescence directed forwards; the venter of the male on the terminal half has not the tufts of hairs which are to be seen in the species of the westermanni group. Male genitalia reddish brown, white pilose, shaped as usually, with the upper middle lamella not deeply emarginate, and with the two horn-like lateral appendages shining reddish and curved upwards. 14 210 Annals of the South African Museum. Spimes of the ovipositor black. Legs entirely reddish-yellow, with black coxae and with the hind femora distinctly imfuscated above; the hairs are white and rather long, chiefly those of the hind pair; hind tibiae of the male with scattered but long inner villosity; hind femora less thickened, not much more robust in the male, with two rows of strong reddish spines placed on small tubercles; hind tibiae at end with 2-3 bristles, and moreover in the female with several strong reddish bristles on both sides; tarsi bristly on the underside; claws red with black tips; pulvilli yellowish. Wings hyaline in both sexes, but in the female with a faint yellowish tint towards the middle. Veins dark reddish, blackened in the terminal half; second submarginal cell regular and with a short terminal stalk; first posterior cell broadly open; third posterior cell only a little narrower at end than at base; the lower veins of the first and of the third posterior cell are at the same distance from the hind border of the wing; anal vein wavy. Axillary lobe broad; alula rounded, glassy, without fringe. LEPTOMYDAS Nivosus, Gerstaeker 41868. A normal species with the back of thorax dullish and less dis- tinctly striped in both sexes, and with a shining black abdomen, which has rather narrow yellowish rings. A couple of specimens from Matjesfontein (Cape) November 1910 (R. M. Lightfoot), one male from Cape Town, and another from Hex River. (L. Péringuey). For description of the male see Gerstaecker; the terminal club of the antennae is sometimes dark reddish. The hitherto unknown female is of about the same size as the male, its abdomen being not much thicker. The face is ferruginous on the sides; the hairs of head and base of abdomen are shorter; there are 4-5 postvertical bristles on each side. Abdomen shining black, with rather broad yellowish hind borders on the segments 2-5; bullae small and shining black; the hairs are white, short and scattered, except at base, those of the four terminal segments being directed forwards; venter shining reddish, but blackened at end; spines dark reddish or blackish. Legs as in the male, but Jess villose and with thinner, almost not thickened hind femora; hind tibiae with less developed bristles. Wings as in the male, but with a little more darkish tint in the middle. Nervuration regular in both sexes; the terminal crossvein of the third posterior cell rather short, shorter than the basal one. M. Bezzi, The South African Mydaidae (Diptera). 2411 LEPTOMYDAS HUMERALIS, Gerstaeker 1868. Closely allied to the preceding species, but distinguished by the more distinctly striped back of the thorax and by the broadly yellow face in both sexes. But as these are characters of lesser value, it is possible that both species may be united as a unique one under the present name. A couple of specimens from Bushmanland, Jackals Water (Cape), October 1911 (R. M. Lightfoot); an additional female specimen from Triangle, (Cape), January 1895. Postvertical bristles less distinct; anterior ocellus well developed. The male not hitherto described, is almost the same as that of the precediug species, but has an entirely yellow face. The neura- tion of the wings is the same, but there is a tendency for the ter- minal stalk of the discoidal cell to be lost, the third posterior cell becoming thus punctiform at end, as represented in Gerstaecker’s figure. LEPTOMYDAS BRAUNSI, spec. nov. Closely allied to Awmeralis, but distinct in the longer villosity of the hind tibiae in the male, and in the rufous abdomen of the female. Type o and type Q, a couple of specimens in the writer’s col- lection, from Willowmore, (Cape), 15th November 1920, taken in copula by Dr. E. Brauns. in whose honour the species is named. From the European lusitanicus, which presents the same sexual dichroism, tho present species is distinguished by the longer antennae and by the spinose hind femora. It is possibly allied to fulviventris, Bigot, from the Sudan, the name of which must however be changed, as there is an earlier L. fulviventris, Leon Dufour 1850, which is the female of lusitanicus. Oo Q. Length of the body 18-19 mm.; with the antennae 21-22 mm.; of the wing 12-15 mm.

Axillary lobe broad; alula rounded. LEPTOMYDAS OPACUS, Sp. nov. Nearly allied to the three preceding species, but easily distinguish- able in the male sex by the opaque abdomen which is shining at the base only; from the following species it differs in the much less developed and almost wanting yellowish hind border of the abdo- minal segments. Type ©, a unique specimen from Dunbrody, Cape Colony, 1901 (Father J. O. Neil). oc. Length of the body 18 mm.; of the wing 12 mm. Head entirely black, shining on middle of frons and face, densely clothed with whitish dust on sides of both and on the occiput; it is clothed with long and dense white hairs; there are also some dark yellowish postvertical bristles. Antennae long, quite black, with the usual proportion in the length of the joints as in the preceding species. Anterior ocellus distinct. Proboscis black, of the usual length and shape. Back of thorax dullish black, grey-dusted and distinctly striped, clothed with whitish hairs, which are longer on sides and in front of the scutellum.

Axillary lobe broad; alula rounded, hyaline, not fringed. LEPTOMYDAS PAGANUS, Gerstaecker 1868. A very distinct species, on account of the entirely opaque abdomen of the male, and of the more numerous and broader yellowish wings of the abdomen in both sexes. Male from Cape Town; female from Stellenbosch (Cape). (L. Pé- ringuey). The male is as described by Gerstaecker, but has the face entirely black and the terminal club of the antennae reddish in the middle; pleurae black; hind tibiae nearly bare; wings hyaline, with the veins not bordered by fuscous; second abdominal segment shining at the base only. A co example from O’Kiep, Cape, agrees better with Gerstaeker’s description, the face being yellowish and the an- tennae wholly black. The female not described hitherto is more briefly hairy and thicker; the face is ferruginous at sides; the front ocellus is well developed; the antennae are entirely black; the thorax is rather shinng on the back, chiefly on the posterior half, and is more broadly reddish on sides and on pleurae; Abdomen shining black, © with reddish-brown terminal segments and reddish-yellow venter; the segments 2—7 with broad yellowish hind borders, that of the second interrupted by the shining black bullae; the three terminal segments with the usual pubescence directed forwards; spines of the ovipositor blackish or reddish brown. Legs as in the male, but with thinner hind femora; claws red with black tips. Wings hyaline, with reddish veins. LEPTOMYDAS FLAVIROSTRIS, Sp. Nov. Allied to the preceding, but distinct by the almost entirely yellow- ish colour of the antennae and proboscis, by the more lightly coloured body and legs, and by the almost whitish wing veins. Type © and an additional examples of same sex, from Hex River, (Cape) December 1883. (L. Pérmguey). The present species is probably allied to L. dispar, Loew, from Mozambique. © Length of body 18-20 mm.; of wing 12-13 mm. Head entirely M.

Thorax entirely reddish, but blackish and erey-dusted in the middle of the back, clothed with yellowish hairs, but the pteropleural and notopleural tufts are whitish. Scutellum and mesophragma shining reddish, the latter with long whitish hairs on the sides. Squamae and halteres dirty whitish or yellowish. Abdomen shining reddish-brown; with more or less darkened basal tergites; it is clothed with long white hairs on the second basal segments, and with short ones on the remainder, those of the ter- minal four segments being yellowish and directed forwards. The yellow hind borders of the segments are broad and present from the 2nd to the 7th; the bullae are shining black, large and very striking. Spines of the ovipositor reddish. Legs entirely yellowish, with reddish coxae, and with short whitish or pale yellowish pu- bescence; hind femora very little thickened, with strong yellowish spines below; hind tibiae with strong yellowish bristles; claws yellowish, with black tips. Wings whitish hyaline. with entirely pale yellowish or whitish ves. Second submarginal cell rather dilated below before the end (but regular in the second example), with short terminal stalk; first posterior cell broadly open; terminal stalk of the discoidal cell very short or even absent, the third posterior cell being punctiform at its outer end; the two lower veins of the first and third posterior cells are at equal distance from the hind border of the wing. Note. A small male specimen without label, may be considered as that of the present species. It measures only 15 mm. in length and the wing 10 mm. The head is as in the female, with longer and entirely whitish hairs; proboscis and antennae as in the female and of the same colour. Thorax dull black on the back, reddish on the sides and on the pleurae; the hairs are longer and quite white, even on the back which is striped. Scutellum shining black; meso- phragma reddish-brown. Abdomen dark reddish brown, with the two basal segments shining and clothed with long white hairs; the other segments are opaque, with short hairs, 3-D with narrow whitish hind border and with a broad grey band before it, becoming 216 Annals of the South African Museum. broader on segments 6-7 hind border of the second segment yel- lowish, with broad shining black bullae. Genitalia reddish, white haired, of usual shape. Legs entirely yellowish, whitish-haired; hind tibiae with short villosity; hind femora only a little thickened, with less developed spines below; they appear therefore almost simple and unarmed. Wings hyaline, with dark yellowish veins and with regular nervuration, the first posterior cell only being more narrowed at end. LEPTOMYDAS SUBCLAUSUS, Sp. nov. Closely allied to the preceding species, but distinct by the short proboscis and by the much more narrowed first posterior cell which is almost closed at end. The short proboscis of the present new species is like that of lusitanicus. Type Q and an additional specimen of the same sex from spect takel, Namaqualand (Cape) October 1890 (R. M. Lightfoot), but the latter specimen is doubful having shorter and broader wings, and having a differently coloured abdomen, with black lateral spots. 3. Length of body 17 mm.; of wing 13 mm. Head entirely shining black, with dark grey dust on the sides of frons and of face, and on upper part of occiput; it is clothed with long whitish hairs. Anterior ocellus not distinct.

Bezzi, The South African Mydaidae (Diptera). 217 ginal cell, the first posterior cell being thus almost closed at border ; discoidal cell sessile at end, the outer end of the third posterior cell being punctiform; the lower veins of the first and of the third posterior cell are placed at the same distance from the hind border of the wing. HALTERORCHIS, gen. nov. A peculiar genus, distinct by the very short antennae and by the rudimentary proboscis. Body smooth, almost bare. Head with the vertex not hollowed, No ocelli. Mouth opening almost closed, proboscis rudimentary. Antennae shorter than the transverse diameter of the head; third joint equal in length to the two first jomts together; terminal club greatly swollen, rounded, as long as the whole antennae. Eyes bare, Thorax with nearly bare metapleurae. Abdomen with a peculiar pattern; terminal segment of the ovipositor exserted, and with a circlet of thin and long spines; bullae very minute.

A small species, very distinct, besides the generic characters, by the peculiar abdominal pattern. Type Q, a unique specimen from O’Okiep, Namaqualand, (Cape). Q. Length, of body 9 mm., with the antennae 10 mm.; of the wing 8 mm. Head black, but densely grey-dusted even on the middle of the frons, only the distal end of the ocellar tubercle being shining black; it is clothed with rather long white hairs; postvertical bristles less developed. Frons and face with parallel sides, very broad, broader than one eye. Antennae reddish-brown, with the terminal club bright reddish but infuscated outwardly; first joint only a little longer than the second, with long white hairs; third joint as long as the two first joints together, its terminal portion 218 Annals of the South African Museum. (or fourth joint) very short; the terminal club is as long as the whole antenna, and almost sphaeroidal in front view. The inferior part of the head is shining black; the very small rudiment of the proboscis is yellowish. Thorax black, dark grey-dusted, quite opaque even on the pleurae, with reddish humeri; with short, scarce, whitish hairs disposed on four longitudinal stripes on the back; the pleurae are practically bare, with short hairs on the pteropleurae, and with less distinct ones on the metapleurae. Scutellum grey-dusted on the basal half, shinmg black on the apical half, bare, but concealed below the long whitish hairs of the hind part of the mesonotum ; mesophragma grey-dusted, bare. Squamae and halteres whitish. Abdomen rather short and broad, of a dull blackish colour, dark reddish-brown on middle of the tergites and rather shining black on sides; it is clothed with scarce whitish hairs at base, and with yellowish pubescence, directed forward on the two terminal segments. The peculiar pattern consists in a yellowish band at the base of the segments 2-5, but more developed on 2 and 3. This band is broadly interrupted in the middle, and does not reach the sides laterally; it is thus reduced to two transverse spots, one on each side of the segments, with the external ends bent behind at right angles; moreover there are narrow yellowish rings at the hind border of the segments 2-6; the venter is entirely reddish, unspotted. The last segment of the ovipositor is reddish, with dark spines. Legs slender, entirely yellowish, with blackish coxae and darkened femora; they are nearly bare, but all the tibiae and chiefly those of the hind pair are beset with yellowish long bristles; hind femora simple, with some scattered yellowish bristles below; claws and pulvilli yellowish, the former with black tip. Wings greyish-hyaline, with reddish veins. The first basal, the discoidal and the third posterior cell have parallel sides and are all of about the same width; the third -poste- rior cell is punctiform at end. The second longitudinal vein ends into the first at equal distance as both branch of the cubital fork, the three terminal segments of the first vein being thus all of the same length. Alula very small and transverse, without fringe. MYDASELPIS, gen. nov. A very characteristic genus, distinguished from all the others on account of its pedunculate abdomen and of its deeply punctulate and brightly coloured body. The neuration of wings shows also some peculiarities. Head with little hollowed vertex; in front view it is narrowed M. Bezzi, The South African Mydaidae (Diptera). 219 below, the eyes having no parallel sides, but being convergent inferiorly. Anterior ocellus distinct, at least in the female; and placed in the middle of the frons. Eyes bare. Antennae long, longer than the transverse diameter of the head; third joint more than three times as long as the two first joints together; terminal club elongate, as long as the third joimt. Proboscis thick, with broad terminal flaps, projecting, but proportionately short being no longer than the half of the length of the antennae or nearly so. Palpi not distinct. Thorax bare, even on the ptero- and meta- pleurae; it is rugulose and deeply punctulate on the back. Squamae without fringe. Abdomen distinctly pedunculate, at least in the male, its narrowest point being on the third segment; it is almost bare and strongly sculptured with impressed points on the tergites, and with less marked ones on the sternites. Male genitalia of usual shape; ovipositor of the female with the circlet of spines, but with the terminal segment not exseited. Legs rather stout and nearly bare; hind femora more thickened in the male, in both sexes armed underneath with two rows on very prominent tubercles. Hind tibiae straight, without terminal spur, and not bristly except at end. Wings broad. Second longitudinal vein straight and ending into the first at some distance from the end of the upper branch of the cubital fork. Second submarginal cell appendiculated at base, rather narrow, puffed up below towards the middle with a long terminal stalk. Fourth vein at end meeting at costa with the first, the first posterior cell being thus closed but not stalked. Discoidal call of trapezoidal shape, shortly stalked at end, its apical cross vein being nearly parallel with the basal one and more or less shorter; there are only three posterior cells, the second (or third) being fused with the fourth (or fifth); third posterior cell as broad or broader than the discoidal cell, and about as broad at base as at end; the lower veins of the first and of the third posterior cells are placed on the same line, at equal distance from the hind border of the wing; anal vein rather straight, the terminal part of the anal cell being thus less curved below, and its terminal stalk being rather short. Praefurca very short, or nearly absent; in the type species the base of the third longitudinal vein is prolonged backwards into a long stump, which is much longer than the praefurca itself and has a free end. Alula transverse, not fringed. No hind-marginal cross vein; ambient vein thin, sometimes less visible in the female. 220 Annals of the South African Museum. Type: MyYDASELPIS PERINGUEYI, sp. nov.

A very distinct, handsome fly, looking like a species of Systropus or Cosiops. i Type o, a single specimen without the antennae from Hex River, (Cape) 27th December 1882, labelled by Bigot as Cephalocera perin- gueyi; the specific name been maintained here, in honour of Dr. L. Péringuey. 5. Length of body 17 mm.; of wing 13 mm. Head black, but the face reddish with a narrow black median stripe; only the middle of the frons is shining, the rest being clothed with a dark grey-dust. Anterior ocellus rudimentary. The golden yellow hairs are bushy at the vertex, on the sides of the frons anteriorly, and on the face. Basal joints of the antennae red, the first less than twice the second in length; the remainder wanting in the type. Proboscis red, even on the terminal flaps, only the median line of the upper side being black, it is short measuring only 1:5 mm. in length. Thorax pecu- liarly regulose-punctulate on the back; it is dull black, but the neck, the humeri and a spot above them, and the postular cells are red. The pleurae are dull black, with the callosities above the front coxae, the upper part of the pteropleurae and the root of wings red. On the back there is a very scarce and short golden pubescence, dis- posed on two longitudinal stripes; the pleurae are bare. Scutellum dull black and bare, a narrow hind border on the back of the meso- notum being red; mosophragma deep black, narrowly red anteriorly at the sides, bare, Squamae yellowish; halteres reddish.

Venter black, with the Qnd, 8rd and 6th sternites red, but all the sternites with narrow yellowish hind borders; it is bare and rather shining. The tergites are also a little shining at sides, but they are opaque on the whole median part chiefly on account of the deep and strong sculpture which is distinct but less developed on the venter. Legs entirely yellowish, with reddish coxae; they are almost bare; the prominent tubercles and the strong spines of the underside of the not much tkickened hind femora are reddish-yellow; claws and pulvilli yello- wish, the former with black tips. Wings yellowish along the costal and subcostal cells, broadly infuscated in the middle to the end, ereyish-hyaline along the hind border except in the middle where a faint infuscation is noticeable, apically the fuscous is extended to the end of the first posterior cell, which is narrowly infuscated along its fore border and broadly infuscated at its base, but hyaline on the remaining part; the fuscous patch has a prominent tooth towards the outer end of the discoidal cell. The costa, the subcosta and the base of the other veins are yellowish; the remainder of the veins is reddish and then blackish towards the end. Anal cell, axillary lobe and alula hyaline. Second submarginal cell narrowed at end, terminal stalk of the discoidal cell very short; terminal stalk of the anal cell likewise short; base of the third longitudinal vein much prolonged beyond the praefurca and ending free into the first basal cell.

NOMONEURA, gen. nov. I have founded here the present new genus for some species. which are much like those of Leptomydas, being distinguished chiefly on account of the stalked first posterior cell, all the veins of the wing-tip uniting with the first. Owing to this character they were formerly placed in the following genus Cephalocera; but as this last genus shows very extraordinary features in the neuration of the wings, while in the present new genus the neuration is quite nor- mal (whence the proposed name), it is necessary. to separate them. The genus seems to be represented also in the Oriental Region, the Indian species Cephalocera annulata, Brunetti 1917, with short pro- boscis and neuration of wings as in nigra, Macq., being possibly referable to it. The main characters of the new genus are as follows. Head not much hollowed at vertex, less pilose, in the female nearly bare. Eyes bare; anterior ocellus well developed. Antennae very long, more than twice as long as the transverse dia- meter of the head; the fourth joint appears as a part of the club, which is elongate and not much swollen. Proboscis thick, with broad terminal flaps, rather long, projecting as far as the middle of the third antennal joint or even further. No distinct palpi. Thorax bare, even the metapleurae with only a few hairs or quite bare. Abdomen not pedunculate, more or less elongate, with the surface smoth and nearly bare, or only a little hairy at the base. Male genitalia of the usual shape; ovipositor with the circlet of spines, but with the segment bearing them not exserted. Legs slender; hind femora less thickened even in the males, armed inferiorly with two rows of not very long spines which are placed on non-deve- loped tubercles; hind tibiae straight or only faintly curved, with no terminal spur, but with well developed bristles. Wings with all the terminal veins uniting with the first, the first posterior cell being thus closed at end and stalked; the end of the second vein into the first is distant from that of the upper branch of the cubi- tal fork; second submarginal cell appendiculated at base, of regular 294 Annals of the South African Museum. shape or swollen at the base inferiorly; terminal stalk of the discoi- dal cell very short or even absent, at any rate the terminal cross- vein of the third posterior cell is much shorter than the basal one; the lower veins of the first and third posterior cell are rounded, placed at the same distance from the hind border of the wing, but with a re-entering angle at their junction; lower vein of the third posterior cells, that is the upper branch of the fifth longitudinal vein, issuing from the second basal cell, as in all the preceding genera; anal vein wavy; anal cell with a more or less elongate point, and with a more or less short stalk. Alula rounded, not fringed; ambient vein very thin; no hind-marginal cross vein, thus there are only three posterior cells, the second being fused with the fourth. Type: Mypas rascrarus, Wiedemann 1828. The known species may be distinguished as follows: — A. Proboscis short, not projecting beyond the mouth; fourth longitudinal vein meeting at costa with the first posterior cell being thus sessile at end paradora, N. sp. B. Proboscis long and projecting; first posterior cell stalked. (2) 1.

Type female from Pretoria, 149th. September 1915.. (H. K. Munro), The present species is a true Nomoneura, but in the characters of the proboscis and of the first posterior part of the vings, it agrees with Halterorchis, which has however very different antennae, and with Mydaselphis, in which the abdomen is stalked and deeply punctate. Q Length of body 146 mm.; of wings 11 mm.; of antennae 3-6 mm. M. Bezzi, The South African Mydaidae (Diptera). 225 Head shining black, the face dark reddish; the short scattered hairs are darkish near the antennae, longer and whitish at vertex and below. Anterior ocellus well developed. Antennae very long, black; first joint twice as long as the second; third joint cylindrical, long, not thickened; terminal club elongate a little shorter than the third joint, dark reddish in the middle. Proboscis very short, not projec- ting beyond the mouth, with narrow terminal flaps. Thorax shining black and nearly bare; there is a short pale pubescense on the sides of the back, and on the propleurae and metapleurae there are very sparse white hairs; the humeral calli, a stripe above the notopleural line, the postalar cells and a stripe before the scutellum are reddish; the pleurae are dark reddish above and below. Scutellum and me- saphragma reddish. Halteres blackish. Abdomen shining black, bare, with very scarce and short pale hairs near the base and with a few impressed points; the two terminal segments are reddish, with dark short hairs directed forward; venter shining black, with the two terminal segments reddish; spines of the ovipositer reddish. Legs simple, entirely pale yellowish, even to the end of the tarsi; coxae and trocanters dark reddish; claws reddish with black tip; hind femora less thickened, elongated, but with strong yellowish spines below. Wings with a faint grey-yellowish tint and with yellowish veins; second submarginal cell appendiculed and ventricose below ; first posterior cell sessile at end; third posterior cell with regular base and with punctiform eud. NoMONEURA FASCIATA, Wiedemann, 1828. Easily distinguished from all the other species on account of its greater size and of its banded abdomen. One male from Zululand, M’fongosi, December 1911, (W. E. Jones). The present species seems to be one of the most common and most widely spread in South Africa. It has been many times descri- bed and figured, being also the unique species included in Loew’s work. It is rather variable in the coloration of the body, chiefly of the thorax, but the abdominal bands are always distinct. Cephalocera bellardii, described and figured in 1862 by Prof. Ber- toloni from Mozambique, is not distinguishable from the present species. This species shows some peculiarities in the neuration of wing. The lower veins of the first and third posterior cells are nearer to the hind border of the wing, and have a less pronounced angle at their junction; the stalks of the first posterior cell and of the anal cell are much shorter than in the other species. 15 226 Annals of the South African Museum. NoMONEURA PARTITA, Gerstaecker, 1868. Probably only a form of the following species. Described from South Africa in the Museum at Berlin, but not found subsequently, and not represented in the collection before me. NoMONEURA CALLOSA, Wiedemann 1828. An easily recognisable species of smaller size but of rather stout body, very well figured in both sexes by Wiedemann. A couple of specimens from Namaqualand, the male from Spring- bok, November 1890, the female from O’Okiep (Cape) September 1890 (R. M. Lightfoot). In these examples the hairs of the head are dark brownish, not whitish as described by Wiedemann; the wings of the male are very faintly infuscated. The posterior veins of the wing are more distant from the hind border, and the stalks of the closed cells are longer than in fasciata. NoMONEURA NIGRA, Macquart 1858. The darker and smaller species of the genus, with practically black legs and wings. Macquart has described this species from South Afrika, but it was never recorded subsequently. I refer to it two male examples, pinned on the same pin, from Jackals Water, Bushmanland, (Cape), October 1911. (R. M. Lightfoot); they seem to correspond to the variety from Port Natal, recorded by Walker, List, VI, Suppl. 41, p. 374. Length of body 11-12 mm.; of wing 8-9 mm. Head shining black, clothed with pale yellowish, not dense and never bushy hairs, occi- put with narrow grey stripe near the eyes. Antennae very long, black, with dark reddish terminal club; third joint 4-5 times longer than the first two joints together; the club is elongate but is shorter than the third joint. Proboscis black, long, projecting to about the end of the third joint of the antennae. Thorax entirely black, even on the humeri and pleurae; on the back it is opaque, almost bare, with four longitudinal stripes of whitish pubescence. Pleurae rather shining, bare, with scarce, whitish hairs on the ptero- and metapleurae Scutellum and mesophragma black, a little shining, rugulose, bare. Squamae and halteres black. Abdomen black, even on the venter and at end, rather shining; 2-3 and 4th segments more or less coir) broadly red, and also the 5th, but !more narrowly; it has whitish M. Bezzi, The South African Mydaidae (Diptera). 2217 hairs at the base, but is almost bare on the remainder. Even the horn-like appendages of the male genitalia are black. Legs black, with dark reddish tibiae, tarsi and underside of the four anterior femora; hind tibiae curved, with short and scarce inner villosity; spines of the hind femora dark yellowish and thin; claws and pul- villi reddish, the former with black tips. Wings blackish, with only a narrow hind border and narrow stripes of the same cells -clear. Veins blackish. The stalk of the first posterior cell is well developed: the posterior veins are rather distant from the hind bor- der; terminal stalk of discoidal cell very short or even wanting. CEPHALOCERA, Latreille, 1829. With Ectyphus the present genus is the most characteristic one of the South African fauna; because in its true sense, as here restric- ted, it is exclusively South African. The genus was founded by Latreille chiefly on the characters of the thin and acute proboscis and of the long capitate antennae, for the type Mydas longirostris, Wied.; but the insect figured in Cuvier’s Regne animal, nouv. édit. (Masson), Insectes, pl. 172, fig. 14, seems to belong to another species. The genus was subsequently treated by Macquart, 1834 and 1838, by Westwood, 1841, and by Walker, 1854, who has tabulated the known species on p. 372-376 of the 2nd Supplement of the ‘List’. 17 species have been recorded as belonging to it; but the Australian gracilis, Macq. is a Triclonus, and maculipennis, Westw. a Miltinus ; dentipes, Macq. and the two other American species described by Philippi belong to Mitradetus. Thus Gerstaecker in 1868 listed only 41 African species, which, with the addition of bellardit, Bertol., make 12, as reported in my Catalogue of 1906 and in that of Ker- tesz of 1909. No African species has been described subsequently. But of these 12 South African species, Westermanni and rufithorax are to be placed in Leptomydas; botta, Macq., from Arabia is in all probability a Syllegomydas, Macquart’s figure of it showing no pro- jecting proboscis; bellardii is a synonym of fasciata; and _ fasciata, partita, cullosa and nigra belong to Nomoneura as shown above. There remain thus in the genus Cephalocera only 4 species, all of which correspond in one important venational character, which is unique in the whole of the family. It is very curious that no Dipterologist has mentioned this character, which is recognisable even in Wiedermann’s figures of longirostris co and Q pl. 4 IV, fig. 21, and is well shown in Gerstaecker figure of catulus, pl. 1, fig. 2. This peculiar character is derived from the branching of the 228 Annals of the South African Museum. postical or 5th longitudinal vein beginning much beyond the lower cross-vein and much nearer the hind border of the wing; the upper branch of the postical fork originating thus near the end of the anal cell, and not from the second basal cell as is the rule. The posterior veins become therefore completely parallel with the hind border of the wing, as is the case with the Nemestrinidae. It there- fore shows that the lower vein of the third (or fourth) posterior cell is not Cu 14, as interpreted by Prof. Arias, but is M 4, in accordance to the new conception of Dr. Tillyard. It may be noted that the genus Cephalocera is distinguished from the genus Syllegomydas, besides the venational characters, by the very different form of the proboscis and of the antennae. The characters of the genus Cephalocera as here restricted, are as follows: — Head hollowed at vertex. Eyes bare, converging below in front view; anterior ocellus rudimentary. Antennae very long (but in one case short), with the fourth jomt forming a complex with the third (and not with the club); terminal club elongate and less swollen (but in one case rounded and swollen). Proboscis very characteristic, long, thin, acute at end, with very small terminal flaps; palpi very short, with rounded end and long-haired. Thorax with long hairs, chiefly in the middle; ptero- and metapleurae hairy ; surface smooth, like that of the abdomen. Abdomen elongate, but not pedunculate; male genitalia of peculiar form, with the horn-like appendages or style converging interiorly with their ends in con- tact; ovipositor with terminal circlet of spies. Hind femora of the male more, of the female less thickened, armed in both underneath with two rows of spines placed on distinct tubercles; hind tibiae straight or only a little curved, without terminal spur, or only with a short obtuse apophyse. Venation of the wing lke that of Lepto- mydas, but with the fourth longitudinal vein ending into the first, and therefore the first posterior cell is closed and stalked; discoidal cell very narrow at end, its terminal cross vein being much shorter than the terminal cross vein of the third posterior cell (but some- times the opposite takes place; lower vein of the third posterior cell originating from the anal cell near its end; anal vein rather straight, bent below at end; ambient thin; no hind marginal cross vein. Type: Mypas Lonerrostris, Wied. 1829. The species, with the addition of a new one, can be distinguished as follows: — (8) 1. Antennae very long, as long as or even a little more than the proboscis ; antennal club less swollen and elongate, but shorter than the third antennal M. Bezzi, The South African Mydaidae (Diptera). 229 joint; hind tibiae quite simple at end; back of thorax with whitish or reddish hairs; wings more or less infuscated, with a well developed alula. 2.

CEPHALOCERA LONGIROSTRIS, Wiedemann, 1829. The type species of the genus, at once distinguishable by its slender and entirely yellowish legs, though the hind femora may be infuscated on the apical half (Wiedemann’s original figure). 1 oS and 2 9 from O’Okiep Namaqualand, (Cape) September- October 1890 (R. M. Lightfoot); another co without data. This species has been many times described and figured. The abdominal tergites are entirely shining, black above in both sexes and reddish on sides, like all the sternites. Only the two terminal segments of the female abdomen show the peculiar pubescence di- rected forward. Legs clothed with very long white hairs, which are less developed in the female; coxae blackish-brown; claws red- dish, with black tips. Discoidal cell narrower than the third posterior cell, ith terminal cross vein very short, sometimes punctiform, at any rate much shorter than the terminal cross vein of the third posterior cell, and even shorter than the discal cross-vein. Second submarginal cell with broad end, the three terminal portions of the first longitudinal vein being about the same length. CEPHALOCERA FASCIPENNIS, Macquart, 1838. Distinguished from the preceding species in the more thickemed and more blackened hind legs, and in same peculiarities of the ve- nation. One male specimen, without the abdomen, from Knysna, Cape 230 Annals of the South African Museum. Colony, October 1916, (L. Péringuey), may be considered to be this very imperfectly described species. Head shining black, with ferruginous face, clothed with bushy white hairs. Antennae and proboscis entirely black, the latter as long as the former, measuring 2.6 mm. Back of thorax black, with reddish humeri and sides; it is clothed with long white hairs, dis- posed on four broad longitudinal stripes with a median much nar- rower one. Pleurae shining black, grey-dusted above the front coxae, bare, but with long white tufts on the ptero- and metapleurae. Squamae whitish; halteres pale yellowish. Scutellum shining black ; mesophragma dull reddish brown and rugulose. Only the two basal segments of the abdomen are present in the unique specimen at hand; they are clothed with long white hairs, are shining black above, reddish-yellow on sides and reddish-brown on venter; hind border of second segment yellowish, with broad, shining reddish- bullae. Legs with shining black, white-haired coxae; those of the two front pairs are entirely reddish, with long white hairs; hind legs with thickened femora, which are shining black above and red- dish below, clothed with long white hairs, and are armed under- neath with strong black spines placed on reddish tubercles; hind tibiae straight, almost bare, simple at end, reddish at base and blackened on the remainder, as are also the tarsi. Wings broadly infuscated, with hyaline stripes on the discoidal and second submar- ginal cell, and with hyaline apex and posterior border, though the latter is faintly shaded towards the middle. The veins are blackish, but reddish at base in the anterior part of the wing. Second sub- marginal cell much narrowed at end, the middle one of the three terminal segments of the first longitudinal vein being thus much shorter than the other two; discoidal cell broad at end, while the third posterior cell is almost punctiform there; the discoidal cell is as broad in the middle as the third posterior cell. Alula well deve- loped and rounded. CEPHALOCERA UMBRINA, Gerstaecker, 1868. This species, the distinction of which from the preceding one is not an easy matter, was described from the Cape and has not been recorded subsequently. It is not in the collection before me; the type is in the Museum at Berlin. CEPHALOCERA CATULUS, Gerstaecker, 1868. Even of this species I have not seen any example; it was descri- bed from the Cape and the type is in Berlin. The original figure M. Bezzi, The South African Mydaidae (Diptera). 231 shows perfectly the characteristic shape of the base of the third posterior cell. CEPHALOCERA BRACHYCERA, Sp. nov. A species typical in other respects, but very different from all the others at present known on account of its very short antennae. Type oO’, a unique specimen from O’Okiep, Namaqualand, (Cape), September 1890, (R. M. Lightfoot). The species shows a superficial resemblance to Leptomydas paga- nus, Gerst., from which it is at once distinguished, besides the generic characters, by the much shorter antennae, and by the entirely shining abdomen of the male. oO.

Anterior ocellus rudimentary. Antennae shorter than the transverse diameter of the head, and only half as long as the proboscis; they are black, with the terminal club bright reddish; first segment rather swollen, with long white hairs, once and a half as long as the short second joint, third segment cylindrical, twice as long as the two first segments together, its terminal part (fourth joint) as long as the first joint and distinctly thickened; terminal club very swollen, pyriform, about as long as the third joint, with a short and obtuse apical protuberance. Proboscis shining black, 3 mm. long, of the thin and acute shape typical of the genus. Thorax entirely black, with reddish humeri; on the back it is opaque with the beginning of two broad stripes of grey dust in front and between them a much nar- rower middle line; it is clothed with blackish or dark reddish hairs, only on the sides along the notopleural line there is a stripe of white hairs; pleurae shining black, grey-dusted above the fore coxae, the metapleurae with a dense tuft of whitish hairs. Scutellum shining black, with reddish hairs; mesophragma black, bare, dark grey-dusted. Squamae pale yellowish; halteres with yellowish stalk and blackish knob. Abdomen entirely shining black from the base to the end; the segments 2-7 with rather broad yellowish hind borders, white and shining on the sides, that of the second segment interrupted by the broad, ovate, shining black bullae; at the base there are long white hairs, on the rest the hairs are short, scattered, 232 Annals of the South African Museum. whitish, a little more abundant on the sides and at end; venter shining reddish, with the 3-4 terminal segments blackened, clothed with rather long and abundant whitish hairs. Genitalia short, shining black, reddish at end, clothed with whitish hairs, with the horn-like appendages convergent and with their tips im contact. Legs with shining black, white-haired coxae; those of the two an- terior pairs reddish-brown, clothed with long yellowish or darkish hairs; hind femora greatly thickened, shining black above, dark reddish below, with a long whitish villosity, armed below with strong black spines placed on reddish much prominent tubercles. Hind tibiae rather thick, a little curved on the terminal half, with long rather rigid darkish or yellowish hairs, and provided at end, on the internal angle with a rather stout, obtuse process, which bears 4-5 strong reddish bristles. Tarsi reddish-brown; claws reddish, with black tips. Wings quite hyaline and iridescent, with black veins. Second submarginal cell regular, with long appendix at base, not much narrowed at end; stalk of the first posterior cell well developed: discoidal cell much narrower than the third poste- rior cell, and much narrowed at end, its terminal cross-vein being about as long as the discal cross-vein, and much shorter than the terminal cross-vein of the third posterior cell; this latter is exceed- ingly broad at base, its lower vein (M 4 or Cu 1) ending (or origi- nating) very near the end of the anal cell; axillary lobe long and proportionately narrow; alula very narrow, rudimentary.

Plates CX VI—CXXII of Crustacea). Of the eleven species with which the present contribution is con- cerned five are offered as new to science. About one of the species there is an element of mystery worthy to be solved by some one among the many skilled carcinologists of our day. That publication of this treatise has been considerably delayed is due to causes with which writers on systematic zoology are only too familar. But with regard to the comparative meagreness of results as here exhi- bited, it may be explained that numerous specimens have been carefully examined, yielding results necessary for museum purposes, while supplying no addition, or none under present circumstances applicable, to scientific nomenclature.

Milne Edwards, while like Herbst and Audouin (in Savigny) leay- ing the species in Cancer, practically defines a new genus by the statement, ‘‘A great oval cavity on each pterygostomian region (disposition of which we know no other example in the Crustacea)’. For the typical species he curiously misquotes Herbst (1790) and Audouin (1825) as authorities for C. esculptus ‘and then gives the species as C. sculptus instead of the correct exsculptus. Heller’s Hypocoeius being preoccupied was changed by Miss Rathbun into Aypocolpus. HypocoLpus EXScULPTuUS (Herbst). 1790. Cancer exsculptus, Herbst, Krabben und Krebse, vol.

Plate CXVI. The specific name from SAcqpagic, eye-lash, and ox, shade, allu- des to the striking mass of setae surrounding the eyestalk. This organ is of moderate length, curved, slender except at the base, and furnished with a very small cornea. Another important feature which appears to distinguish this from the allied species in the shape of the extensive fourth joint of the third maxilliped, largely excavate at the imner angle, while the three following joints are insignificant in size, the first folded against the fourth joint and each furnished with long setae. The first and second maxillipeds are in fair agreement with the figures in Savigny’s Egyptian Crus- tacea, pl. 2, figs. 1), 1, for the species named Macrophthalmus leachii by Audouin and Cleistotoma leachii by Milne Edwards, except that the exopod of the second mavxilliped is here relatively longer. Savig- ny’s plate shows a very dilated vibratory lamina for the second maxilla, yet not so dilated as it is in our species. The palp of the mandible as figured on Savigny’s plate must, [ think, be much exaggerated in size compared with the trunk. At any rate in our species it folds against the trunk, the third joint closely adjoining the incisor edge. The first and second antennae are very small. The figures are more magnified than the other details in order to show the charac- ters of the two little flagella in the first pair, the few-joimted fla- gellum in the second pair and its setose peduncle. The first parae- opods or chelipeds like the other limbs are setose: the fingers are slender, meeting at the tips and at one point of the inner margins by help of the single tooth of the movable finger. In all the 238 Annals of the South African Museum. remaining peraeopods the pointed finger is perfectly straight, shortest in the fifth pair. The third and fourth pairs are remarkably alike, with the fifth jomt widening distally and the sixth with considerable proximal breadth distally narrowed. The outer sides of these setose joints show oblique stripes. In the pleon the first segment is the widest and shortest, the second less wide but slightly longer, the rest gradually narrowing to the rounded setose telson. The cara- pace is about 9°5 mm. in breadth by about 6 mm. in length. Collected in Delagoa Bay by Mr. K. H. Barnard. (Oct. 1912). S.A.M. No. 2134. BRACHYURA ANOMALA. Famity HOMOLIDAE.

All the peraeopods are wanting except one each of the second and fifth pairs. Also the central spine of the rostrum is broken and the supra-ocular spines are absent, probably by accidental fracture. But attention may be called to the slender long joint of the eye- stalk and that of the first antenna, both of which though quite stiff have the appearance of being composed of many little short joints. The thick following joint of the eye-stalk carries three short setae. Locality, Cape Natal W. 3%, N. 43 miles; depth 35 fathoms. S.A.M. No. A 1353.

Among the specimens of Malacostraca entrusted to me by Dr. W. S. Bruce leader of the ‘‘Scotia” expedition (the Scottish National Antarctic Expedition) were two which I referred to Caleinus talis- mani, A. Milne-Edwards and Bouvier. Supposing that identification to have been correct, the species now to be described may with some confidence be referred to the same genus. For both species show the unusual feature to which in 1914 I directed attention, namely, that in the second and third maxillipeds the trunk of the exopod greatly exceeds in breadth the endopod. In the figures and descriptions of the species of this genus to which I have had access I have not found any record of this character. It may be noticed in passing that Milne Edwards in his illustration of the second maxilliped of Birgus latro shows a very broad exopod. It is a per- plexing circumstance that the specimens now to be dealt with have the right cheliped larger than the left. CALCINUS ASTATHES, N. Sp. Plate CXVII. The group of specimens to which I have given a name from the Greek word ceraéijs, unsteady, agree however, as above noted, in having the right cheliped larger than the left, which is contrary to the accepted definition of the genus. The specimen from which the figures are drawn is in another respect abnormal, in that the larger uropod is on the right. But in another specimen of approximately equal size this abnormality does not occur, nor in the three smaller specimens. In one of these latter the inferior length of the right eye-stalk is much accentuated. In the specimen figured this charac- ter is very slightly indicated. In the present species the telson is 240, Annals of the South African Museum. longer than broad with a smoothly rounded end, not as in C. tali,- mant broader than long and apically notched. The chelipeds are similar in structure and armature of tubercles and setae on the last three joints, the movable finger rather longer than the palm, a little more so in the smaller cheliped; both have black spooned apices. The fingers of the ambulatory limbs, with black ungues, are longer than the preceding joint. The stout little fourth peraeopod is sub- chelate; the slender fifth is minutely chelate, with long curved setae over the chela and the several joimts carrying various groups of setae set at different angles. The carapace of the specimen figured had a length of 17 mm., with greatest breadth 9 mm., the left eye being 65 mm. in length, the long terminal joint of the peduncle of the first antenna 3°5 mm., finger of smaller cheliped 5 mm., of the larger 5°5 mm.

It is true that a leading character in the original definition of this genus is the perfect symmetry of the pleon. But Faxon in describing his Cancellus tanneri writes, ‘‘The abdomen as a whole is not quite bilaterally symmetrical the right side being more swollen than the left, a condition which gives the abdomen a slight twist to the left.’ Alcock also, while describing the uropods as quite symmetrical, adds ‘as also or nearly so is the telson.” CANCELLUS MAKROTHRIX, N. sp.

The specific name, from the Greek uaxzodbor§, long-haired, refers to the remarkably setose character displayed in almost all parts, including the carapace, pleopods and telson, and reaching an extreme Thomas R. R. Stebbing, South African Crustacea. 24 in the cheliform fourth peraeopods, while even the eye-stalks are hairy. The broad hand and short finger of the equal first peraeopods carry many rows of stiff setae. The spooned apices of thumb and finger are black. The fourth to the sixth joints of the ambulatory limbs are broad, the much narrower seventh joimt is very slightly longer than the sixth, with an upturned black apex. The slender finger of the fourth peraeopods does not reach beyond the broad dark rasp of the preceding jomt. The whole of the cheliform fifth peraeopod is slender. The telson, broader than long, with slightly excavate hind margin is a little unsymmetrical. It has a feature difficult clearly to represent, a deep hollow across the middle which resisted flattening out. The median length of the carapace is 21 mm. its breadth to the rear 22 mm. The mouth-organs offer some points of interest, though, as these parts in the Paguridae are rather seldom figured, their use for comparison is diminished. In the second maxilla it will be noticed that the apex of the vibratory plate is unusually narrow. In the first maxilliped opportunity has been afforded for showing that the terminal part of the exopod is not as in the other maxillipeds subdivided into numerous jointlets. In the second maxillipeds the principal joint of the exopod is very long and broader than the joints of the endopod. In the third maxilliped it is less important as compared with the endopod, but the endopod itself has a feature probably of specific importance, namely, in the straight row of fourteen little tubercles near the inner margin of its third joint. The specimen is a female, with the sexual openings conspicuous at the bases of the third peraeopods. “ Locality, Algoa Bay, depth 10 fathoms 8.A.M. No. A 1544. GEeNus EUPAGURUS, Brandt, 4851.

Among the numerous species assigned to this genus I have failed to recognise one which combines the characters displayed by the specimen here to be described. It makes some approach to E. spi- nulentus, Henderson, which I have noticed on p. 260 of the reference given above for the genus, but a comparison of the details prevents any union between the two forms. 16 249 Annals of the South African Museum. The carapace is 16 mm. long, the fifth pleon segment 2°5 mm., the sixth 2 mm. and the round-ended telson 3 mm., the eyes 65 mm. in length. The likeness to the Pylochelidae is dissipated by the obvious twist of the pleon and the asymmetry of the uropods, that on the left being much the larger. In both uropods the ex- ceptional smallness of the inner branch should be noticed. The front of the carapace is obscurely produced between the ophthalmic scales, below each of which is produced backward a faint ridge of the carapace, its front margin forming a smal] denticle on the outer side of each scale. These scales are wide apart, bilobed, not denticulate, but the larger inner lobe produced into an acute apex. The eye-stalks widen to the black corneae, which outreach the acicles. Of these the longer inner setulose branch is not calcified, the outer branch is denticulate. As in the first antennae so in the- second the terminal joint of the peduncle is the longest, and in the second the flagellum is devoid of setae and more than four times as long as the peduncle. The small mandibles have a sharp molar ridge on the inner side, the third joint of the palp the longest and very setose. The first maxillipeds are small and very delicate. In the second pair the sixth joint of the endopod is notably broader than the fifth or seventh and very setose, the exopod elongate. In the third pair the stem of the exopod narrows a little abruptly distally, this narrowing accentu- ated by the prominence of a group of setae, the stem not reaching the apex of the fifth joint of the endopod. The latter is elongate, its last four joints subequal in length, attached end on, fringed with setae. , The right cheliped is considerably the larger, its hand armed with two conspicuous rows of denticles on the palm, one continued irre- gularly along the broad-ended finger, the other on the inner side of the thumb. Between thumb and finger a gap is concealed by long setae; the outer margin of the thumb is dentate following an incon- spicuous row of denticles on margin of the palm. The wrist is strongly dentate on the inner margin. The smaller left cheliped has a hand not unlike its companion, but with the fingers longer in comparison with the palm. The second and third peraeopods have fingers longer than the preceding joint, curved, fringed with setae. The fourth peraeopod has a short, curved finger, with sharp apex. The fifth has a diminutive finger, with setules on the blunt end. Locality Mossel Bay, depth 19 fathoms. S.A.M. No. A 4537. Thomas R. R. Stebbing, South African Crustacea. 243 EUPAGURUS DEPROFUNDIS, h. sp. Plate CXX. The present species agrees with H. placens in the numerous rows of teeth or sharpened tubercles with which the hands and wrists of the large chelipeds are furnished. But in many details the two species differ not a little. Here the telson has a curiously produced lobe with calcified rim at the right extremity, and the right uropod instead of the left is the larger. The long flagellum of the second antenna here has the fringing setae which are wanting in the other species. In the delicate structure of the first maxillipeds the figures show slight but decided differences and in the third maxillipeds the sixth joint of the endopod is notably longer than either the fifth or seventh instead of being subequal to each. Note also apical tooth of its fourth jomt. The fourth peraeopods are alike in the two species, but the fifth differ in that the little unfingerlike finger is here facing a produced blunt apex of the preceding joint making an apology for a chela, In regard to the second and third peraeopods it may be noticed that the fourth jot of the third is shorter than that of the second pair, but as to the third joint the comparative length is reversed. The carapace of the specimen, a female, measures 14 mm. in median length, with a breadth to the rear of 10mm. The eyes are 5 mm. long. Locality Cape Morgan N.%/, W. 13 miles; depth 250—320 fathoms.

Two specimens were obtained by Dr. Gilchrist in the year 41900 when dredging with shrimp trawl from the ‘Pieter Faure” ata depth “about 300 fathoms” ‘Table Mountain E. by S. 40 miles”. S.A.M. No. A109. The specific name is the Latin word signifying “a thicket of thorns”. The size, number, and arrangement of the spines in this species, though they may not exclude the possibility of its not being fully adult, at least mark it off as distinct from all other forms that I can find hitherto described. A superficial resemblance to the Thal- assocaris stimpsoni figured by Bate in his ,,Challenger” Report, pl. 117, may partially account for its undeserved neglect. In number of spines it may have a competitor in Ceratomysis spinosus, Faxon, but there the arrangement of them is quite different. The telson is reminiscent of that figured by Faxon for his Calastacus stilirostris, 11 which however the uropods are very distinctive. The pointed rostrum with no ventral teeth is surmounted by a succession of four large spines, succeeded by two much larger on the median line of the carapace with a little tooth close behind the second. The antero-lateral angle of the carapace is produced into a spine much outstripping the eye and followed by a curved margin fringed with short equal spinules. The margin is then continued in a straight lime to a small distal tooth, with the hind margin at right angles to the laterals, strongly excavate in the middle but convex for a space adjoining the distal tooth above-mentioned. On the pleon the spines are present in rather baffling numbers. As shown in the plates the lower part of one segment carried 18 large spines, the full complement in another is 25; the sides and broad apex of the long quadrangular telson muster 18 which are plumose; to these must be added 2 small lateral spines or setae, and on the lower half some dorsal spicules are discernible. The first five segments of the pleon are rather short, the sixth nearly as long as the telson. The uropods are longer than the telson, with Thomas R. R. Stebbing, South African Crustacea. 245 dense fringes of long plumose setae except on most of the outer margin of the exopod. Low down this has a small tooth such as often marks the “diaeresis” or oblique dividing line, which however could not here be perceived. A faint longitudinal dorsal ridge carries minute spines. The eyes have the cornea broader than the eye-stalk, colour dark. In the first antennae the first joint is very long, carrying an elon- gate spine near the base; this has an upturned pomt; of the fla- gella one is slender, obscurely six-jomted, the other stout, about as long as first joint of the peduncle. Second antennae carying many long spines, the scale with two conspicuous but smaller divergent spines near the rounded setose apex. Mandibles with four- (or five-) toothed cutting edge, followed by a long row of setules and spinules to a slightly projecting dark mass of denticles, the trunk gradually narrowing from this broad front. First maxillae with outer plate narrow, apically carrying four spines. Second maxillae with narrow apical portion of endopod many-spined. First maxillipeds having two basal joits broad, the rest short and narrow. Second maxilli- peds having on one ‘side the sixth and seventh joints distinct but on the other in one piece, probably a malformation. Third maxilli- peds with last four joints very narrow, seventh very short, sixth very long, twice as long as the fifth, fourth curved, two-thirds the length of the sixth, third as broad as long. Finger of first peraeo- pods with two spines on narrowly truncate apex. In second pair finger and thumb each tipped with a spinule, wrist here longer than hand instead of rather shorter as in preceding pair. The three following peraeopods have a short curved finger, hand much longer than wrist. Fifth peraeopod more slender than third or fourth. First pleopod with endopod not half as long as exopod and carrying a small coupling process with hooks at the apex. Length of specimen measured round the dorsal curve about 145 mm. INDEX.

THE following Monograph gives an account of the Drassid spiders of South Africa. The term South Africa is meant to apply to the region south of the 15° latitude and not to political South Africa. Even so, the boundary is an artificial one arachnologically, for, as far as can be seen from the distribution of the species at present known, certain Cape Province * species occur in South-West Africa, and others spread northwards to the East African equatorial region, and certain Abyssinian species spread south to the same region. Whether the interpenetration is carried further, the known material does not show. Mediterranean species, however, merge with Abyssinian, and the latter with Arabian species, and so on. To attempt to work out the distribution of species, therefore, requires the knowledge of a greater number of specimens recorded from various regions than are available at present. It is probable, however, that as Drassids are small, agile spiders, protecting themselves by living under any fallen object which can provide shelter, there is no reason why any barrier short of the Sahara Desert should impede their distribution. In fact, the distribution of the Drassids seems parallel to that of Ants, as set out by Mr. G. Arnold of the Rhodesia Museum in the preface to his Monograph on “ Formicidae,’ Ann. 8.A. Mus., vol. xiv, pt. 1. Drassidae as a rule do not feature largely in collections, because not only has special search to be made for them, but their agility makes them difficult to capture. In addition, owing to the uniformity in appearance of the species of various genera, it is only sexually mature specimens that can be identified with certainty, and such Specimens are only obtainable at certain periods of the year. This being so, the records of species are naturally of a somewhat scattered and isolated nature; nevertheless the genera and species here dealt with most probably include the major portion of the Drassids of South * Ail the localities recorded in the following pages are in the Cape Province of S. Africa, save where definitely stated otherwise; e.g. S. Rhodesia, Natal, S.W. Prot., ete. la 252 Annals of the South African Museum. Africa. New species and genera will undoubtedly be found from time to time in the vast territory under consideration, but for the most part further collecting will help more towards working out the dis- tribution of the species now known and dealt with than in increasing them. Arrangement. In his standard work, Histoire Naturelle des Araignées, tom. 1, and Suppl., tom. 11, Simon deals with the family Drassidae, and it is on his divisions and tables of genera that the arrangement of the following Monograph is based. Simon divides the family into four sub-families, all of which are represented in Africa. The various genera of these families, however, are not all known from Africa. Keys are given in the following pages to include all genera of Drassidae given by Simon, together with other genera since added to the other sub-families, in order to facilitate the subsequent placing, or identifica- tion, of new genera which may be found in South Africa from time to time. Sub-families, groups, and genera are dealt with in the following pages in the sequence into which they fall in the keys based on their natural characters. Species, however, are described or recorded in alphabetical order, and not in the sequence into which they fall in their keys. As this Monograph, however, is intended to deal only with the Drassidae of South Africa up to the latitude 15° S., only those species actually found up till now in this particular region are described and keyed here. In some genera the general characters and appearance are so uniform, and sufficient specific characters on which to work out keys are so lacking, that keying the species of such genera has often been a matter of difficulty. In all cases of doubt, however, a glance at the figures of the sexual organs will settle the identity of a species almost at once. Every description is based on type specimens, personally examined ; in the few cases in which this has not been possible, the author’s description is quoted in inverted commas. My thanks are due to Mr. 8S. Hirst of the British Museum, and Mr. J. Hewitt of the Albany Museum, Grahamstown, for facilities given in examining the type specimens in their charge.

Of the above genera, only 2 are recorded from South Africa, namely, Hemicloea and Platyoides. As only 1 species of Hemicloea has been recorded, it may be doubtful whether the genus really occurs in South Africa. Platyoides, however, is widespread in South Africa. Trachycosmus, Pyrnus, Rebilus, Corvmaethes, and Henucloeina have not as yet been found in South Africa. 254 Annals of the South African Museum. Gen. HEMICLOEA, Thorell.

PLATYOIDES LATERIGRADUS, Poc. 1898. P. laterigradus. Pocock in A.M.N.H., vol. ii, ser. 7, p. 219, pl. viu, fig. 2. ‘* Colour.—Carapace and mandibles mahogany brown; sternum and basal three segments of legs ochre yellow; legs from patellae to tarsi lightly infuscate, though paler below ; abdomen ashy grey, paler beneath. “ Carapace.—A little longer than broad, about as long as the tibia and half the protarsus of the first and as the femur of the fourth leg; anterior median eyes separated by a space slightly exceeding their diameter, but separated from the anterior laterals by a space which equals almost two diameters. * Mandibles.—With one largish tooth near the base of the inferior border; hairy below, the hairs arising from the summits of little papillae ; front of mandibles sparsely setose. “* Legs.—Also sparsely setose, not spined; protarsi and tarsi of first and second lightly scopulate below; the scopulae of the second thinner than of the first; patella and tibia of first and fourth about equal, and less than patella of second; fourth leg exceeding second leg by the length of its tarsus. “ Abdomen oval, nearly twice as long as wide. 258 Annals of the South African Museum. “ Vulva as in pl. vil, fig. 12; inferior spinners short and conical, scarcely longer than broad. “ “ Measurements in Millimetres.—Total length, 13; length of cara- pace 4, width 3-3; length of first leg 11, of second 13, of third 10, of fourth 12 (measured from base of femur). ** Toc.—Estcourt, Natal, 4000 ft.” To this description Pocock adds: “In size and colouring this species certainly resembles P. abrahami (O. P. Cambr.)”’ ; also, “‘ Since neither Mr. Cambridge nor Mons. Simon detected in P. abrahami the tooth that I have described in laterigradus, one is compelled to assume that it is absent in the former species.” PLATYOIDES LEPPANAE, Poc. 1902. P. leppanae.

Abdomen testaceous, with median and lateral dark bands, the former narrowing posteriorly. Sternum reddish brown, dark-edged. Eyes.—-Anterior laterals at least 3 times a median’s diameter from the latter. Posterior laterals smaller than the anterior laterals and quite twice the latter’s diameter from them.

Record of New Localities.—2 92 (No. 5130). Pocaltsdorp, George Div. (Miss L. Leipoldt, 1899.) These specimens agree in size, colour, markings, and vulva with Pocock’s types. The chelicera, however, have 3 very distinct teeth, not 2 only, as stated in description, loc. cit. Further, there appears to be a slight discrepancy in the description of the legs. Of the statements “tarsi and protarsi of the anterior pairs lightly scopulate beneath,” as given in the description, and “tibia and protarsus of first and second leg without scopula,” as given in the key to the species, the former is more correct according to the type specimens. The tibiae are not scopulate, and the metatarsi bear a fairly dense clothing of hair on the under surface which, though long, is scopulate in appear- ance; the tarsi are slightly more densely clothed: the tarsal claws bear 2 small basal teeth in addition to the 2 median larger ones. Also the median, dark, raised portion of the vulva is pointed posteriorly, as mentioned in the description; from the figure given, it would appear that the reverse was the case.

Pedipalps.—Tibia, tarsus, and palpal organ as in fig. 12B. Measurements.—Carapace: 2 2 mm. in length, ¢ 2 mm. Total leneth,25mm.; ¢ 44mm. The vulva depicted in fig. 12a seems to be identical with that figured by Purcell in L. Schultze’s Zool. 8.W. Afr., Bd. xin, pl. x, fig. 29, as Callilepis lineatipes. As there is only the one type specimen of lineatipes, which is not available, direct comparison is impossible. The description, however, appears to fit in with that of Upognampa : that this is a distinct genus from Callilepis there seems little doubt. The eye formation is quite distinct and constant; the spinners are distinct, and the bases of the median spinners are non-tuberculate. Also the size is uniformly smaller than in Callilepis, and the coloration is hghter, both of which help to confirm the other differences. Hence, from description and figure, I conclude that Callilepis lineatipes, Purc., should be transferred to the genus Upognampa. The following specimens are also recorded :— 2 99 (B 2979).

The vulva of the 2 appears as in fig. 34, loc. cit. ; in all specimens, however, the median ridge between the two lateral dark plaques curves outwards on each side into a somewhat T-shaped form, the lateral portions being concave posteriorly, and often dark and prominent and forming shallow arches; the anterior convex margin is just shown in fig. 33. In some specimens the T is very faint and appressed, and in others it is dark and prominent. Also in some specimens the median anterior tongue is situated immediately anterior to the T, and is dark and button-like. The range in variation in the vulvae seems to vary with the age and condition of the specimen, and though the same features are present in all, some are more prominent to the detriment of others.

In this genus the sexual organs are the distinguishing specific characters ; other characters are so uniform in each species that the few available for specific purposes are practically all included.in the key given in the previous pages, the descriptions in each case being made from type specimens ; hence in the following species of Purcell’s the descriptions are not repeated, the key and figures quoted below being deemed sufficient. New species are described as usual. DRASSODES LOPHOGNATHUS, Pure. 1907. D. lophognathus. Purcell in A.M.N.H.

Among the South African species described as Melanophora by Purcell, were included certain forms which differed in eye formation, colour, etc., to the usual forms. One such specimen was later described by Tullgren as a new genus, Camilla, one of the main characters of the genus being a metatarsal comb on legs III and IV. This I found to be common to all the South African species of Zelotes (Melanophora), and also to those of Setaphis, although not so strongly marked in the latter genus. Shortly afterwards a paper by L. Berland in Bull. Mus. Hist. Nat., 1919, No. 6, notes the same fact with regard to Zelotes, and describes and illustrates the form, function, and occurrence of this comb most admirably. Also, he proposes the name Camullina for the reception of species such as that described by Tullgren, owing to the pre-occupation of the name Camilla given to them by that author. Under Camullina, therefore, are described species which differ from Zelotes as follows :— Colour light brown, abdomen often testaceous. Anterior row of eyes, seen from in front, procurved ; laterals larger than the medians. Posterior row, seen from above, distinctly procurved ; median eyes larger than the laterals, angular, and contiguous posteriorly. Sternum narrower and more oval, and from 14-12 times as long as broad ; about 14 times as broad at the point of greatest width as anteriorly ; sometimes slightly produced or narrowed anteriorly. Metatarsi III and IV with apical combs of long bristles usually on under surface. Gen. CAMILLINA, Berland. Syn. Camila.

The Drassidae of South Africa. 351 Gren. ZELOTES, Gistl. This name was proposed by Gistl, in 1848, to take the place of Melanophora, C. Koch, 1833, owing to the latter name having been preoccupied by Meigen in 1803 for a genus of Diptera. The name, however, was overlooked by later workers, and Prosthesima was substituted for Melanophora by L. Koch in 1872, owing to the aforesaid preoccupation of that name. Both Melanophora and Prosthesima have been largely used by various workers, but Petrunkevitch in 1911, Bull. Amer. Mus. Nat. Hist., vol. xxix, puts the synonomy right and establishes Zelotes as the name for this genus. ZELOTES, Gistl. Key to 29. (23) 1 No light patch on inner surface of femur I. (12). 2.

The specimens are slightly smaller and darker than those described by Purcell; in addition, the vulva shows strongly a character only weakly represented in Purcell’s specimens, and not shown in his fig. 51. This character consists of two distinct “ tunnels ”’ in the space above the circular plaques; they are arched over by a continuation of the lateral curved lines, which do not merge in the median dark lines, as fig. 51 shows, but curve down and are superimposed on them. The arches or tunnels so formed are akin to those figured in P. fulaginea, Purce., pl. xv, fig. 44. There is great similarity also to the vulva of P. simom, Pure., which is sometimes not so big centrally as in fig. 49. One of the Winterhoek specimens in which the above character is not so conspicuous agrees very well with a specimen from the summit of Table Mountain, which shows it more strongly than the other Peninsula specimens; one from Kalk Bay Mts. (C. Penins.) shows the character fairly well, and one from Port Elizabeth shows traces of it. One, however, from Table Mt. is as shown in fig. 51, the 366 Annals of the South African Museum. arches being almost indistinguishable ; this specimen appears newly moulted. Also 1 9 (B 2771). Gt. Winterhoek Mts. (4800-5000 ft.). (R. W. Tucker, November 17, 1916.) A 2 example (B 3211) from Salisbury, 8. Rhodesia (R. W. Tucker, April 1917), also appears referable to this species. Tullgren (loc. cit.) records a specimen from a height of 3000-4000 ft., Kilimandjaro, G.E. Africa, which, according to his description, is black and differs slightly in eye formation from montana. The specimen from Salisbury is also practically black and very large (carapace, 3-5 mm. ; total length, 9-2 mm.), but agrees with montana. The vulva is coarse, and has the two dark central lines, figured by Purcell and Tullgren, masked or absent. Both Cape and Rhodesian specimens have the patella and tibia subequal to the cephalothorax, as given by Tullgren for the EK. African example. In none, however, are the anterior median eyes so widely separated (2 diameters) as in Tullgren’s example, and, further, the median ocular area is wider posteriorly, 7.e. the medians slightly nearer to the laterals than to each other. Unless the northern examples ultimately prove to belong to a new species, P. montana appears to have a wide distribution, namely, from C. Peninsula to G.E. Africa. ZELOTES MONTIVAGA, n. sp.

(abdomen distended). The specimen from Natal agrees with above details, but is darker and redder in colour, and the abdomen is normal in size. (Carapace, 25mm. Total length, 5-5 mm.) This is the first record of this genus from 8. Africa, and in some respects it diverges from the 8. American type; the anterior median eyes are much larger, the anterior row is not procurved, and its clypeus is barely equal to the diameter of an anterior lateral eye ; also, the posterior median eyes are oval and slightly larger than the laterals. Apart from these ocular differences, the specimens agree with the generic description, and it seems valid to record that genus as now occurring in 8. Africa. DIAPHRACTUS LEIPOLDTI, Pure. 1907.

Dodds); numerous specimens of both sexes from Pretoria, December—January (H. K. Munro), bred from flowers of Composite plant, Gerbera jameson. To the original description may be added: Eyes in life light green, with reddish tinge. The black middle spots of the abdomen are at base of fourth and of fifth segment, but they are distinct only in the female, being often concealed below the hind border of the preceding segment; moreover, in the male the last segment has a black basal band and two spots at end. Craspedoxantha marginalis unimaculata, var. nov. One male specimen from Gt. Winterhoek Mt., Tulbagh, 5800 ft., April 1916 (R. M. Lightfoot). Distinguished from the preceding in being of a distinctly darker colour and with the bristles dark yellowish ; the apical spots of scutellum are fused together to form a single broad black spot, which fills up the space between the a. sct. Craspedoxantha polyspila, sp. nov. (PEST fies 5.) Nearly allied with marginalis, but distinct by the quite yellowish thorax, and by the scutellum having two additional black spots at insertion of the b. sct.

All the bristles yellowish; three i. or. Thorax entirely yellowish, with no blackish parts on back, and without black spots on pleurae or on breast ; on the back there is a short yellowish pubescence ; there are some small, deep black, rounded spots, as follows: four disposed in a square at 506 Annals of the South African Museum. the insertion of prsc. and dc., two at sides behind the prst., and two near the a. sa., and two on postalar calli, one internal, the other external. Of the four black spots of scutellum, two are smaller and basal, and two a little broader and apical, these latter being distinctly more distant from each other than those of marginalis. Postscutellum and mesophragma yellowish, unspotted. All the bristles yellow; scp. not distinct; de. on the line of the a. sa. ; two mpl. Halteres pale yellowish. Abdomen entirely yellowish, opaque, with two pairs of approximated small black spots, two at base of fourth and two at base of fifth segment, in part concealed below hind border of preceding segments. Ovipositor as long as the three last abdominal segments together, yellowish, with a black basal spot on each side and with narrow black tip. Venter yellow, unspotted. Legs entirely yellowish, unspotted; bristles of front femora yellow; spur of middle tibiae dark yellowish. Wings (fig. 51) with same neuration and pattern as in marginalis, but the small cross-vein distinctly more oblique. TERELLIA, Robineau-Desvoidy, 1830. There are two South African species before me, one of which has banded wings, and thus belongs to the subgenus Sitarea, R.-D., the other with unspotted wings, and thus a Terellia, s. str. They are as follows :— 1. (2) Wings with two dark bands and with some isolated fuscous spots ; scutellum black spotted ; ‘ : . taeniaptera, sp. nov. 2. (1) Wings hyaline, quite avignmtcede soutellurn are potted planiscutellata, Beck. Terellia taeniaptera, sp. nov. (Pl. XIII, fig. 52.) Allied with hysia, Walker, from Sierra Leone, but distinct by the very different wing-pattern, which is somewhat like that of the Kuropean species ruficauda, Fabr., and winthemi, Meig. One specimen from Pretoria, August 1916 (H. K. Munro); but the species is known also from East Africa and even from Madagascar. $. Length of body and wing, 4 mm. Head entirely yellowish. Occiput opaque, with two broad black spots above, united together above the neck and prolonged in a point to reach the upper inner corner of the eyes. Frons with a black ocellar dot, one and one-half times longer than broad; lunula pale yellowish; face narrow, whitish ; peristomialia unspotted, narrower than the third antennal South African Trypaneid Diptera. 507 joint. Hyes ovate, bare. Antennae inserted at middle of eyes, shorter than the face, entirely yellowish ; third joint rounded at end, distinctly pubescent ; second joint rather prominent and black, spinu- lose; arista bare. Palpi and proboscis yellowish. Cephalic bristles yellowish, even the long and acute occipital ones ; oc. strong; two or three or.; genal bristle strong; lower part of occiput with yellowish bristly hairs. Thorax entirely blackish, with reddish humeri, noto- pleural region, and root of wings; it is grey-dusted with yellowish pubescence. Bristles yellowish ; scp. not distinct ; de. before the line of the a.sa.; onempl.; pt.asstrongasthest. Scutellum triangular, flattened above ; it is yellowish, with a broad, triangular black spot in middle ; at sides there are four black spots at insertion of the four sct., the two apical being a little broader than the basal ones. Halteres pale yellowish. Abdomen blackish, grey-dusted, with pale pubescence and yellowish bristles ; hind border of all the segments distinctly yellowish, and, moreover, the first segment with reddish sides; genitalia black, concealed ; venter blackish grey, with reddish hind border of the sternites. Legs short and stout, entirely yellowish, the hind femora with a rather indistinct and incomplete dark ring before the end; hairs pale, bristles yellowish, spur of middle tibiae dark yellowish. Wings (fig. 52) with well-developed costal bristle. Veins yellowish, but blackish on the dark parts; last portions of third and fourth veins straight and parallel; small cross-vein beyond middle of dis- coidal cell; hind cross-vein straight and perpendicular, its distance from the small one being equal to its own length; lower angle of anal cell acute, but not produced. The dark pattern consists of two complete bands and some isolated spots. The first band goes from the end of costal cell across the middle of first basal cell and base of discal and third posterior cells to hind border in middle of axillary lobe. The second band begins at end of marginal cell and goes obliquely across middle of submarginal and first posterior cell to the hind cross-vein and ends at hind border before the end of the third posterior cell. Stigma yellowish, with a black spot at end. An abbreviated band goes from end of stigma to the fourth longitudinal vein, including the small cross-vein. The isolated dark spots are as follows: one in the middle of the marginal cell, extending from costa to the second vein; a broader one at end of submarginal cell and of first posterior cell, forming a triangular patch, which is not extended beyond the fourth vein and is narrowly united with the external oblique band along the third vein ; two spots in the middle of the second posterior cell, a smaller one above, near the fourth vein, 508 Annals of the South African Museum. anda larger one below at hind border ; onein middle of third posterior cell, in the shape of a short streak beginning at fifth vein. Along the fore border of wing, the spots at end of second costal cell, at end of stigma, at middle and at end of marginal cell, are blacker, and thus more striking than the other dark markings. Terellia planiscutellata, Becker, 1903, var. australis, ae. nov. (PIRXGNE hige 3a) A readily recognisable species on account of its quite unspotted, milky wings. Some female specimens from Barberton and Pretoria (H. K. Munro). I have compared them with paratypes of the type species from Egypt. This South African variety differs from the Egyptian form in being of a distinctly greater size (3-5-4 mm. in length), and in having a more yellowish, nearly golden pubescence on back of mesonotum, scutellum, and abdomen. Costal bristle well developed; stigma yellowish; last portions of third and fourth veins straight and parallel; hind cross-vein a little curved, its distance from the small one greater than in. planiscutellata, being equal to or even a little more than its own length (fig. 53). RHYNCHOEDASPIS, gen. nov. This is the first representative of the Oedaspis-group in South Africa, and is distinct from its allies by the form of head and of proboscis, which are similar to those observed in the genus Gonyglossum; that is, depressed head, very prominent mouth border, and very long bent proboscis. Head more narrow than the thorax, depressed above, obliquely prominent forwards, in front view higher than broad. Occiput distinctly concave above and little prominent below, with undeveloped lateral swellings. Frons very long and narrow, twice as long as broad, with parallel sides, not prominent in profile except a little above root of antennae; lunula broad, long, and free; frontal stripe bare. Face narrow, only one-half as long as the frons, with a sharp middle keel and with very prominent mouth border, which is hollowed in the middle above. Parafacialia and peristomialia linear. Hyes bare, narrow, twice as high as broad, placed obliquely. Antennae inserted distinctly below the middle of eyes, as long as the face ; third joint rather narrow, twice as long as the second, rather curved forward at end, but not pointed; arista bare.

Some specimens from Barberton in May, and from Pretoria in ’ October (H. K. Munro). 32. Length of body and wing, 3-5-4 mm. ; of ovipositor, 1-5 mm. Occiput black, clothed with dense grey dust above, whitish below and there with white hairs. Frons with yellowish middle stripe and with broad whitish sides ; lunula whitish. Face whitish; antennae entirely yellowish, like the palpi; proboscis yellowish, with the basal portion darkened below; the sides of the prominent mouth border with short black hairs. Ocp., pvt., outer vt., and basal s. or. white ; inner vt., oc., terminal s. or. and all thei. or. black. Thorax entirely black, dark grey dusted on the back, white dusted on upper half of pleurae and rather shining on lower half; the back and the upper half of pleurae with whitish, tow-like pubescence. Scutellum, post- 510 Annals of the South African Museum. scutellum, and mesophragma shining black. All the bristles black. The rather large calypters are white and white fringed ; halteres pale yellowish. Hind border of mesopleura with three white bristles below the single black mpl. Abdomen of male quite shining black, that of female a little grey dusted; pubescence and bristles black; venter grey dusted; ovipositor black. Legs with black coxae and femora, these latter with yellowish tips, which are broader on middle pair; tibiae and tarsi entirely yellowish; hairs and bristles black. Wings (fig. 55) with dark bands, the hyaline parts between them being distinctly whitish; veins and costa blackish on the dark parts ; yellowish on the whitish parts. There is a blackish spot at extreme base on first costal cell; following this spot a complete basal band, quite isolated from all the others, extending from end of second costal cell and stigma to the hind border in the middle of the axillary lobe ; this band is broader at fore border and goes across the extreme base of the discoidal cell and across the ends of anal and second basal cells. On the terminal half of wing there is a peculiar pattern, formed by four dark bands, all radiating from the fore border; the first is parallel with the basal one and goes from the fore to the hind border in the middle of the third posterior cell ; the second extends along the hind cross-vein and last portion of fifth vein; the third crosses the base of first posterior and the middle of second posterior cell; the fourth goes along the fore border to below the end of fourth vein. The terminal half of wing may thus be described as black with three hyaline indentations at hind border, the distal of which reaches into the submarginal cell, the middle one to the third vein just along the small cross-vein, and the shorter proximal one extends a little into the terminal part of the discoidal cell. Stigma black, with the external upper corner yellowish. MUNROELLA, gen. nov.

The 512 Annals of the South African Museum. dark bands are not much infuscated, and are all equally narrow ; the first begins at fore border, just before the stigma, and ends a little below the anal cell; the second begins at end of stigma, and goes obliquely to the hind border, reaching it in middle of third posterior cell; the third is straighter, begins at fore border at end of marginal cell, and passing over the two cross-veins ends at hind border at end of fifth vein. There is, moreover, a narrow terminal spot at end of first posterior cell, prolonged above into the lower corner of submarginal cell. Actura, Robineau-Desvoidy, 1830. In the present genus, as it is here limited, are included only species with typical wing-pattern ; that is, with two hyaline indentations at fore border and with three at hind border; the remaining species are transferred to Spheniscomyia. The former are as follows :— 1. (8) All the bristles of the occipital border whitish. 2.

Head, its appendages and chaetotaxy as in tetrachaeta, but all the bristles of the occipital border—that is, ocp., vt., and pvt. —quite black. Thorax, scutellum, halteres, abdomen, ovipositor, and legs as in tetrachaeta, but the back of mesonotum distinctly more shining. Wings (fig. 58) with the same pattern; the costal basal stripe broadly united with the stigma; the external of the two hyaline indentations of fore border usually extending into the base of the first posterior cell. SPHENISCOMYIA, Bezzi, 1913. In the present genus are now placed smallish species which have not the typical wing-pattern of Aciwra; they have four or very often 34 514 Annals of the South African Museum. only two sct. and have usually black ocp. ; but there are some species with whitish ocp., and these belong probably to the genus Meta- sphenisca, Hendel, 1914.

Tucker) ; type 9, Barberton, 5th May 1913 (H. K. Munro). 39. Length of body, 2-5-2-8 mm.; of wing, 2-7-3 mm.; of ovipositor, 1 mm. Occiput entirely black. Frons only a little longer than broad, reddish, with blackish ocellar dot and with paler sides; the large lunula is reddish, with whitish reflexions. Antennae entirely reddish, only a little shorter than the face. Face, parafacialia, and peristomialia reddish, the latter unspotted, as broad as the third antennal joint; mouth border not prominent. Palpi reddish, with short black bristles; proboscis dirty brownish. All the cephalic bristles black, even those of occipital border; three 1.or. Thorax short, about as broad as long, quite shining black; on the back there is no distinguishable dust, and the short pubescence is black ; all the bristles are likewise black; scp. not distinct; de. on the line of the a. sa.; two mpl.; pt. and st. rather strong. Scutellum with only the b. sct.; it is shining black, flat above, one-half as long as the back. Halteres quite black. Abdomen shining black, with black pubescence and black bristles ; ovipositor shining black, as long as the abdomen, or even longer when the terminal segments are exserted. Legs black, with yellowish tibiae and paler tarsi; hind tibiae more or less, or even entirely black; front femora with a row of four or five black bristles below. Wings (fig. 62) long, with small or indistinct costal bristle; both the cross-veins perpendicular, straight, and approached together, the distance between them being only a little longer than the small cross-vein. They are entirely blackish to the extreme base, with the following whitish hyaline markings, which are broader in the female than in the male: a small rectangular spot in the middle of the second costal cell; a single indentation at fore border, just after the stigma, in the shape of a short triangle, with the vertex a little below the second vein; three spots in the middle, one in the base of first posterior cell, and two in the discoidal cell, one at base and the other placed more obliquely near the end; there is, moreover, a fourth spot in the second basal 516 Annals of the South African Museum. cell. At hind border there are only two indentations, one in the second posterior cell and one in the middle of the third posterior cell, this last ending at fifth vein; these two indentations are much broader in the female than in the male; moreover, the base of the axillary lobe and the anterior part of the alula are also hyaline, forming thus a third indentation. Spheniscomyia neaver, Bezzi, 1920. (Pl. XIII, fig. 63.) One male of this very distinct species from 8. Rhodesia, Salisbury (D. Dodds). Spheniscomyia binaria, Loew, 1861. (Pl. XIII, figs. 64 and 65.) Some specimens from Pretoria (H. K. Munro). This species shows two distinct types of wing-pattern. The typical form has only one complete fuscous ray at hind border of wing, as is to be seen in fig. 64; in the variety, as shown in fig. 65, there is a second complete dark ray at hind border; this ray is the more or less developed prolongation of the dark tooth in the middle of third posterior cell, well shown even in Loew’s original figure. Even the terminal wing- pattern is somewhat different in the two forms. But I refrain from naming the variety, because it seems to be due to sexual dimor- phism, the supernumerary fuscous ray of hind border being developed mostly in female specimens only. Spheniscomyia quaternaria, sp. nov. (Pl. XIV, fig. 67.) Distinguished from all the preceding species on account of its whitish occipital bristles. Numerous specimens of both sexes from Pretoria and Barberton (H. K. Munro). 3. Length of body, 2-2-5 mm.; of wing, 2:4-2-8 mm.; of ovi- positor, 0-5-0-6 mm. Occiput black, grey dusted. Frons reddish, with dark ocellar area, pale yellowish sides and lunula. Face pale yellowish ; peristomialia whitish, unspotted, not quite as broad as the third antennal joint ; mouth border more prominent than in the allied species. Antennae entirely reddish ; third joint a little shorter than the face, attenuated at end and prominent but not pointed ; arista short, bare, thickened basally. Palpi and proboscis yellowish, the latter short and thick. All the cephalic bristles yellowish, those of the occipital border whitish, the long outer vt. darkened; only South African Trypaneid Diptera. 517 two i. or. Thorax shining black, but clothed on the back with rather dense grey dust and with pale pubescence; all the bristles yellowish ; no distinct scp.; dc. a little before the line of a. sa. Scutellum shining black, less dusted than the back, rather convex above, with only the basal sct. Calypters white; halteres pale yellowish. Abdomen shining black, more or less grey dusted, with pale pubescence ; ovipositor shining black, pale pubescent, as long as the three last abdominal segments. Femora black, with yellowish end; tibiae and tarsi yellowish; front femora with only two long, yellowish bristles below on terminal half. Wings long (fig. 67) and narrow, with blackish veins, which are pale yellowish at base ; costal bristle short ; cross-veins rather distant, the distance between them being about twice as long as the small cross-vein; last portions of third and fourth veins straight and parallel. They are broadly hyaline at base, from the root to the stigma ; within the blackish part there are the following hyaline indentations and spots: two at fore border beyond the stigma, the first with the point at third vein, the second reduced to a simple spot ending at second vein; two hyaline rounded spots in the base of the first posterior cell, more or less completely separated from the two hyaline indentations of the second posterior cell; likewise two spots of greater size in the discoidal cell, more or less separated from the indentations of the third posterior cell. Base of axillary lobe and alula whitish hyaline. The hind border of the wing has therefore four irregular indentations, and may be described as hyaline, with four complete fuscous rays, besides the fuscous apex. Spheniscomyia quinaria, sp. nov. (Pl. XIII, fig. 66.) Some specimens of both sexes from Pretoria, on the plant Lippia aspertfolia (H. K. Munro). 32. Same size as the preceding species, and almost identical with it, but certainly distinct by the following characters : (a) The mouth border is less prominent ; (b) the front coxae and all the femora are entirely orange, without any trace of black; (c) the second hyaline indentation of fore border is more distant from, and about as long as the first, being prolonged beyond the second vein to reach with its lower point the third longitudinal vein; but these two points of both the indentations may be sometimes separated from the spots of the marginal cell, forming thus two isolated hyaline spots in the submarginal cell (fig. 66). 518 Annals of the South African Museum. TEPHRELLA, Bezzi, 1913. In the present genus are provisionally placed the species with four sct. and with white ocp., which have a densely grey dusted back of mesonotum, the de. nearer the line of the a. sa. than to the trans- verse suture, and an Aciura—or Spheniscomyia—pattern of wings, with no hyaline apical spot. They are very close to species of Spathulina, making thus a connecting-link between Ceratitinae and Trypa- neinae. In case the present species should be separated from the typical ones of the Oriental region (which have only two sct.), the name Metasphenisca, Hendel, 1914, may be used for them; the type species gracilipes, Loew, is indeed the same as my Tephrella Cyeep ies 1908. The South African species are as follows :— 1. (2) Second posterior cell quite hyaline, with an isolated fuscous spot at hind border; femora black; wing-pattern of male very different from that of female : : ; ‘ dispar, sp. nov. . (1) Second posterior cell anfnncated: ith ane ‘deal hyaline indentations ; femora orange ; both sexes with the same wing-pattern . distigma, sp. nov. Tephrella dispar, sp. nov. (Pl. XIV, figs. 69 and 70.) Distinct from the allied species by the black femora and by the wing-pattern being very different in the two sexes (a unique case in the genus). Several specimens of both sexes from Pretoria (H. K. Munro). 39. Length of body, 3-2-3-6 mm.; of wing, 3-2-3-6 mm.; of ovipositor, 0-6 mm. Occiput black, densely grey dusted, with a narrow complete yellowish border to the eyes. Frons broad and short, scarcely longer than broad, opaque yellowish with greyish sides and lunula, and with darkened ocellar area. Face short, yellowish grey, with distinct middle keel and with a little prominent mouth border; parafacialia and peristomialia paler, the latter unspotted and narrower than the third antennal joint. Eyes in life lght green, with purplish or reddish reflections. Antennae considerably shorter than the face, entirely yellowish, with obtuse third joint and bare arista. Palpi whitish, with stout black bristles ; proboscis short, dirty yellowish. Ocp. and pvt. white, long, acute; vt., oc., and two or three or., all blackish. Thorax black, densely grey dusted, opaque, clothed with short yellowish pubescence on the back; all the bristles black ; no distinct scp.; dc. on the line of a. sa.; only South African Trypaneid Diptera. 519 one mpl. Scutellum triangular, flattened above, grey dusted, bare, with four black bristles, the apical ones long, strong, and decussate. Mesophragma densely grey dusted, opaque. Calypters white ; halteres pale yellowish. Abdomen entirely black, opaque on account of the dark grey dust; the short pubescence is black, but that of sides is yellowish, like the bristly hairs. Male genitalia rounded, black; ovipositor shining black, as long as the three last abdominal segments. Coxae and femora black, grey dusted ; tips of femora yellowish, especially middle pair; tibiae and tarsi entirely yellowish; front femora below with a row of five to six long blackish bristles. Wings of female (fig. 70) with a more typical pattern; they are blackish, with broad hyaline base, with two broad rectangular (not triangular) hyaline indentations of fore border extended to the third vein, and with two very broad hyaline indentations of hind border, the external of which, occupying the whole of the second posterior cell, extending above into the first posterior cell, and bearing a fuscous isolated spot in middle of second posterior cell, which is to be considered as the rest of the dividing streak of the two normal indentations of this cell; the second, or internal hyaline indentation, extends above the middle of the discoidal cell. Stigma deep black, with the upper external corner narrowly yellow; axillary lobe hyaline, with a fuscous middle patch in continuation of the basal dark band. In the male (fig. 69) the pattern is very different at fore border, because there is no division between the hyaline base and the two hyaline indentations, which are all fused together to form one broad hyaline patch, extending from the base to a little before end of marginal cell; the stigma is yellow, with a black rounded basal spot. The two broad hyaline indentations of hind border are much as in the female, but the isolated fuscous spot in the second posterior cell is shorter, and the axillary lobe has only a fuscous spot above. Costal bristle well developed ; distance of cross-veins a little shorter than the length of the hind cross-vein ; third vein bare; lower angle of anal cell acute, but little produced. Tephrella distigma, sp. nov. (Pl. XIV, fig. 68.) Distinct from all the other species on account of the presence of two rounded hyaline spots in the otherwise entirely black discoidal cell. Type 3g and type 2 from S. Rhodesia, Salisbury, May 1917 (R. W. Tucker). 520 Annals of the South African Museum. $2. Length of body, 3-2-3-5 mm.; of wing, 3-3-3-6 mm.; of ovipositor, 1 mm. Occiput black, opaque, densely grey dusted. Frons narrow, twice as long as broad, opaque yellowish with paler sides. Face pale yellowish; the narrow peristomialia whitish ; mouth border a little prominent. Antennae about as long as the face, entirely yellowish, with the third joint rounded at end and with bare arista. Palpi and proboscis yellowish, the latter very short. Ocp. whitish ; frontal bristles yellowish ; three i. or. Thorax entirely black; on the back it is clothed with dense, opaque grey dust, and with pale yellowish pubescence; the pleurae are less densely dusted, but are always opapue; all the bristles are yellowish; dc. on line of a. sa.; one mpl. Scutellum like back, but less densely dusted, with four yellowish bristles, the apical ones being only a little shorter. Mesophragma lke scutellum. Calypters white; halteres pale yellowish. Abdomen shining black, with faint dust and with thin yellowish pubescence; male genitalia black; ovipositor shining black, a little shorter than the abdomen. Legs entirely reddish, even the coxae; bristles and hairs yellowish. Wings (fig. 68) elon- gate, with small costal bristle; third vein bare; third and fourth veins straight and parallel; distance of the cross-veins a little shorter than the length of the hind cross-vein. Stigma deep black, with a very small yellowish point at upper external corner. Wings blackish, with the following hyaline parts: the base to the stigma and to a little before the anal cross-vein; two equal triangular indentations at fore border with the apex at third vein; two rounded spots in the blackish discoidal cell ; four paired indentations at hind border, two into the second posterior cell, the external of which is prolonged above to reach the third vein, while the internal stops at fourth vein, and two into the third posterior cell, both stopping at fifth vein without entering into the ‘discoidal cell, the internal one twice as broad as the external. Note.—The present species seems to be like Spheniscomyia ternaria, Loew, but is distinct in having no rounded hyaline spot in the base of the first posterior cell, and in having the external posterior inden- tation extended into the first posterior cell; moreover, the ocp. are whitish instead of being black. SUBFAMILY RHABDOCHAETINAE. This subfamily is separated from that of the Schistopterinae on account of the presence of poc. and of the whitish and obtuse ocp. ; South African Trypaneid Diptera. 521 moreover, it is characterised by the subulate third antennal joint and by the distinct costal nick of the wings. In the character of the wing-pattern it is related to the Trypaneinae, having, however, strikingly coloured “ bullae,” peculiar to the group. While the true Schistopterinae have at present not been found either in South Africa or in the Oriental region, the Rhabdochaetinae are represented by all the known genera (one of which, Rhabdochaeta, is also Oriental), as follows :— 1. (2) Wings broad and rounded, with bristly first and third longitudinal veins, with the hind cross-vein placed very obliquely and with the anal cell drawn out in a rather long point ; no poc. : . Perirhithrum, Bezzi. 2. (1) Wings of normal shape, with bare veins, with the hind cross-vein regular -and with the lower angle of anal cell not so produced ; poc. always present. 3.

A very peculiar and magnificent South African genus, which shows some aberrant characters. Perirhithrum marshalli, Bezzi, 1920. (RIE AXEV A) figs 37) Originally described from Natal. I have seen another specimen from Transvaal, from which the present fig. 137 is made, showing the peculiar characters much better than the original photograph of my paper of 1920. Eutretosoma, Hendel, 1914. The present genus is now recognised as belonging to the Rhabdo- chaetinae, with the separation of some heterogeneous elements (bipunctatum, Loew, and frauenfeldi, Schin.), which are removed to the new genus Afreutreta of the Trypaneinae. There are the following South African species :— 1. (4) Very dark or even black species, with black halteres and mainly black legs ; wings more intensively infuscated. 522 Annals of the South African Museum. 2.

A very pale species, described from Natal in my general paper of 1924 on Ethiopian Trypaneidae. RHABDOCHAETA, De Meijere, 1904. Only the following species is known from South Africa :— Rhabdochaeta marshalli, Bezzi. (Pl XV, fig-135:) Distinct from all known species on account of its more robust size, the predominant reddish colour of body, and the very peculiar wing-pattern (fig. 135). Described by me in my general paper of 1924 as another of the numerous and important discoveries made in South Africa in 1905 by Dr. Guy A. K. Marshall, Director of the Imperial Bureau of Entomology, London. RHOCHMOPTERUM, Speiser, 1910. The present genus is doubtfully distinct from the preceding one ; it contains at present two peculiarly coloured species, one of which is described here from South Africa for the first time. South African Trypaneid Diptera. 523 Rhochmopterum munrot, sp. nov. (PIXE toe362) Closely allied with the type species neuropteripenne, Speiser, from Kilimandjaro, but distinct in having the small cross-vein well developed and adorned with only two (not four) white spots at sides, and in having one horn-like orbital bristle. Some specimens of both sexes from Pretoria in June, and from East London (H. K. Munro). 69. Length of body and wing, 2-2-5 mm. ; of ovipositor, 0-6-0-8 mm. Occiput yellowish, with opaque grey dust, and with a black spot in the middle above the neck. Frons about as broad as long, opaque yellowish, infuscated towards the vertex, and with very narrow white orbits; lunula yellowish; a small black dot between the eyes and the root of antennae. Antennae entirely yellowish, as long as the face; third joint very subulate, with a thin, acute point, concave at upper border; arista with a thick yellowish base, but whitish on the rest, bare. Face and peristomialia whitish, unspotted ; mouth border rather prominent. Palpi longer than the mouth, pale yellowish; proboscis short and thick. Ocp. white; inner vt. short and thick, dark yellowish; oc. and poc. whitish, parallel, widely separated ; three or four 1. or., the first of which is black and very thickened, horn-like, while the others are of normal size and dark yellowish in colour. Thorax black on the back, with yellowish humeri and with broad yellowish notopleural stripe; it is densely clothed with opaque, dark grey dust, and shows small black spots at insertion of bristles; mesopleurae yellowish, with a black patch in the middle; sternopleurae black. The chaetotaxy is regular, but besides the usual bristles, which are yellowish with blackish base, there are several erect, whitish, supernumerary bristles, one of which looks like a regular praesutural de. Scutellum yellowish, with long dark yellowish b. sct. inserted on dark spots, and with two pairs of smaller whitish bristles, the apical ones decussate. Calypters and halteres pale yellowish ; mesophragma black, grey dusted. Abdomen entirely yellow, with two rows of dark spots along the middle, and with the last segment shining black in both sexes; male genitalia black ; ovipositor a little shorter than the abdomen, shining black, but dark reddish across the middle. The abdominal segments bear at hind border peculiar, erect, whitish bristles. Legs entirely yellowish, but the four posterior femora with two black spots on the underside, forming incomplete basal and subapical rings; the four posterior 524 Annals of the South African Museum. tibiae with a small black ring at base ; front femora below with four yellowish bristles, and one or two black ones at end. Wings (fig. 136) with deep costal nick, and with double costal bristle; venation of the normal type of Rhabdochaeta. They are hyaline, with colourless stigma, which is, however, narrowly black at both ends. The pattern forms a broad reticulation, with long radiating streaks at border; in the middle it is yellowish brown, with two white dots, one before and one behind the small cross-vein, and these two dots are very striking, being bordered with black; there are, moreover, the usual reddish “ bullae.” In the marginal cell there are two narrow black streaks and another, very characteristic and abbreviated, just beyond the stigma; submarginal cell with three streaks, one basal, one middle, and one terminal, this last being interrupted at base ; first posterior cell with a black isolated streak in the middle at end; second posterior cell with three interrupted streaks at hind border ; discoidal, third posterior, and axillary cells with a few very broad and uncertain hyaline spots, which are surrounded by fuscous. Second costal cell with a perpendicular black streak in the middle. SuBFAMILY TRYPANEINAKH. This subfamily is abundantly represented in South Africa; a thing of great importance, because it 1s very scarce, or even almost entirely wanting, in the centre of the Continent. . The genera are at present not well established, being usually based on uncertain characters of the wing-pattern. They are as follows :-— 1.

PLATOMMA, gen. nov. This new genus is erected here for Trypeta lunifera of Loew, a species which was indicated by its author as being very different from all the others, and as having no allies in the Ethiopian fauna ; it is, however, evidently related with the genus Afreutreta, being very distinct from it as well as from all the others on account of the very peculiar shape of head. Its type of wing-pattern is also unique among Ethiopian Trypaneids. Head very compressed, with the eyes placed almost horizontally, their longitudinal diameter being about parallel with the frons; in front view the head is more than twice as broad as high. Occiput concave, with its upper border very sharp, the head being very close to the prothorax; ocelli very near the vertical keel. Frons a little concave, with parallel sides, twice as long as broad, not at all prominent in profile; lunula broad, rounded, free. Face very short, only one-half of the length of frons; peristomialia narrow; mouth border considerably prominent. Antennae short, but extending to the mouth border; third joint obtuse at end; arista bare; mouth opening exceedingly broad and rounded; palpi short; proboscis very short. Ocp. whitish and thick, obtuse; oc. short ; two or three or. Thorax flat, about as broad as long, with the transverse suture broadly interrupted in the middle ; chaetotaxy apparently complete ; de. before the line of a. sa., very near the suture. Scutellum about © one-half the length of back, triangular, flat above, with four bristles. Abdomen of female with five segments, and with flat, rather long ovipositor. Legs rather stout; front femora with the usual row of bristles below ; middle tibiae with one spur. Wings short and broad, with distinct costal bristle; stigma short; second vein straight ; last portions of third and fourth veins gradually diverging; cross- veins approximated ; lower angle of the anal cell acute, but little produced ; third vein bare; axillary lobe normal. Pattern consisting in a uniform infuscation of the whole wing, without hyaline spots or indentations, with a whitish terminal lunate border. Type: Trypeta lunifera, Loew, 1861. Platomma luniferum, Loew, 1861. (RIX DV e ies 7) A strikingly characterised species, with very peculiar coloration of body and wings. A single, rather badly preserved female specimen from Otjiwarongo, South-West Africa, February 1920 (R. W. Tucker). South African Trypaneid Diptera. 527 To Loew’s good original description may be added: Frontal bristles yellowish ; occipital bristles yellowish ; halteres yellowish ; venter entirely reddish; distance between the cross-veins about as long as, or only a little longer than, the length of the small cross- vein; stigma blacker than the surrounding parts; it is shorter than the second costal cell, and about as long as the first costal cell (ig. 71): EvapuromyiA, Bigot, 1859. Elaphromyia adatha, Walker, 1849. (PISCE ti oani22) A very peculiar species on account of the body coloration and of the shape and pattern of wings (fig. 72). A couple of specimens from Zululand, M’fongosi, March and May (W. E. Jones); East London, July (H. K. Munro). This singular species is widely spread over the Ethiopian region, and seems to be the unique representative of its genus in Africa ; but it shows a good deal of variation, and has thus received several other names (melas, Big., and wula, Loew). Dr. G. Enderlein of Berlin has recently placed this same species in his genus Mesanopin, 1912, among the Ortalids, in Stett. entom. Zeit., 1922, p. 6. AFREUTRETA, Bezzi, 1924. This name was proposed by me for the species previously placed in Eutretosoma, this last genus belonging to the Schistopterinae, as already stated. The species have normal head, with perpendicular eyes; broad frons, usually with black spots near the root of antennae; broad or narrow peristomialia; not very broad mouth-opening; short proboscis ; ocp. of the trypaneinine type. Thorax with interrupted suture, complete chaetotaxy, with the dc. before the line of the a. sa. ; scutellum flat, with four bristles. Abdomen and legs normal. Wings more or less broad, with a broadened second basal cell, but sometimes they are quite normal; they are black, with numerous and small hyaline or subhyaline dots; third longitudinal vein bare; lower angle of anal cell acute, but little produced. All the species seems to be galligenous in their habits; they are as follows :— 1. (4) Wings distinctly dilated, with broadened second basal cell; frons with black spots at root of antennae. 528 Annals of the South African Museum. 2. (3) Wings with very numerous hyaline dots on the disc, and even with some hyaline spots within the stigma : : frauenfeldi, Schin. 3.

Scutellum flat, blunt at end, reddish with blackish-brown base, with four bristles, but without tow-like pubescence. Calypters and halteres reddish. Abdomen entirely red, South African Trypaneid Diptera. 529 even on venter; on back there is an ill-defined darkish middle stripe on the first four segments, the extreme base being, moreover, blackish ; pubescence thin, not tow-like, reddish, longer at sides. Ovipositor red, narrowly black at end, as long as the two last abdominal segments together; male genitalia red. Legs rather short and stout, entirely reddish even on the coxae; bristles of front femora dark reddish. Wings (fig. 73) broad and rounded, but distinctly longer than broad ; costal bristle very small; second vein short; last portions of third and fourth veins gradually, but not much, diverging outwardly ; second basal cell considerably dilated, subquadrate, about as broad as the discoidal cell, which is proportionately short and almost rec- tangular, being only a little broader at end than at base; small cross-vein only a little beyond middle of discoidal cell, its distance from the hind one being only a little longer than the length of the straight and perpendicular hind cross-vein ; anal cell broad; with its lower angle acute, but shorter than the second basal cell. Axillary lobe broad. Stigma short, black, unspotted, about one-half as long as the rather dilated second costal cell. The wings are entirely and equally infuscated, with rounded, not very numerous or striking subhyaline spots, extending across all the cells, except the costal and marginal ones; moreover, there is a broad, rounded, yellowish patch, which extends over the basal half of discoidal cell and over the upper part of the third posterior cell; the fifth vein is yellowish on the portion which runs precisely through the middle of this peculiar patch. Even the dilated second basal cell and the anal cell are a little yellowish. Afreutreta bipunctata, Loew, 1861.

Transvaal, Komati Poort, November 1918 (R. W. Tucker); Pretoria and Barberton (H. K. Munro). I think that this form may be the male of Loew’s semiatra, because in the female the abdomen is only narrowly red at sides near the base, and Loew had only females. All the bristles of head and thorax are pale yellowish ; the entire abdomen or the intermediate segments are broadly red at sides (male); the first posterior cell always shows the two smaJl hyaline dots, besides the larger apical hyaline spot (fig. 81). Spathulina munror, sp. nov. (Pl. XIV, fig. 82.) A species with four sct., allied with margaritifera, Bezzi, from East Africa, but distinguished by the somewhat different wing-pattern (fig. 82). Some specimens of both sexes from Pretoria in March (H. K. Munro). 32. Length of body and wing, 3-3-2 mm. ; of ovipositor, 0-8 mm. Occiput grey, narrowly yellowish at vertex and whitish below.

Thorax opaque, densely clothed with grey dust, the humeri and the 536 Annals of the South African Museum. pleural sutures being more or less distinctly reddish ; pubescence and bristles pale yellowish ; de. much before the line of a.sa.; one or two mpl. Scutellum like back of mesonotum, with reddish hind border ; “a. sct. decussate and much shorter than the b. sct. Calypters white, halteres pale yellowish. Abdomen shining black, with the first segment very narrowly reddish at sides; pubescence and bristles blackish ; venter reddish at base; ovipositor shining black, about as long as the two last abdominal segments together. Coxae and legs entirely yellowish ; front femora with two or three long yellowish bristles below. Wings (fig. 82) with long costal bristle, distance between the cross-veins shorter than the length of the hind cross-vein. They are entirely brown, with hyaline base; second costal cell with a perpendicular dark band in the middle, stigma with a rather broad, not rounded, yellowish hyaline spot at base. Marginal cell with two broad, rectangular, hyaline indentations and with a small rounded spot at end; submarginal cell with four rounded spots along the second vein, one at base, two in middle (the external one sometimes wanting) just below the two hyaline indentations of fore border and fused with them, and the fourth before the end; second basal cell without hyaline spot. First posterior cell with a rounded spot at base and with another at end, both of equal size and narrower than the space between third and fourth veins, and, moreover, in the middle with one or two smaller dots (one above the other); discoidal | cell with two rounded spots near the fourth vein, the basal one broader; second posterior cell with five spots, three at border in the shape of elongate indentations and two at upper corner as rounded spots; third posterior cell with six spots, three at wing-border and three in the middle, the four median spots disposed one above the other and sometimes fused together in the shape of two indentations. Axillary lobe not very distinctly infuscated, with two hyaline inden- tations, resulting from four spots fused together. Spathulina munroi, var. majuscula, var. nov. (Pl. XIV, fig. 84.) Described from East Africa. Spathulina anomalina, sp. nov. (Pl X1Ve fies 873) Distinct from all the other species with four sct. in having only two i. or., black femora, and no hyaline terminal spot on wings. This is an South African Trypaneid Diptera. 537 atypical species, perhaps better placed in Huribia, like other similar species (euryomma and abyssinica), which have, however, only two sct.; it seems to be near Hur. conyzae, Frauenf., from Egypt, which has also four sct. and bicubitate proboscis, but different wing-pattern. One male specimen from Pretoria, January 1923 (H. K. Munro). $. Length of body, 3 mm.; of wing, 3-1 mm.

They are hyaline, with a blackish pattern and with some isolated fuscous spots, but not definitely reticulated. Stigma black, unspotted. Marginal cell with two broad, irregular hyaline spots, which are separated by a _ perpendicular dark streak, which ends at third vein and is quite isolated; sub- marginal cell with a broad hyaline patch in the middle, extending from the second to the third vein, and with a similar broad, rectangular, subapical hyaline spot ; first basal cell with two approximated rounded hyaline spots; first posterior cell with a broad spot near the base, a smaller one in the middle, and another pre-apical, this last united with that of the submarginal cell; the end of the first posterior cell is thus without the usual hyaline spot ; discoidal cell with more than 538 Annals of the South African Museum. the basal half hyaline; second posterior cell mainly hyaline, the upper corner blackish with one hyaline spot, and with an isolated fuscous spot in the middle at hind border ; third posterior cell hyaline, with the upper corner blackish with one hyaline spot, and with two fuscous spots in the middle, one at fifth vein and one at end of sixth vein ; lower angle of the anal cell with a fuscous spot ; axillary lobe quite hyaline, unspotted.

Peringuey). ©. Length of body and wings, 2-2 mm. Occiput black, grey dusted, very narrowly yellowish below. Frons one and one-half times longer than broad, yellowish, with blackish ocellar patch and with broad whitish orbits ; lunula whitish ; face and peristomialia whitish yellow, the latter unspotted and about as broad as the third antennal joint. Antennae shorter than the face, entirely yellowish, with microscopically pubescent arista. Palpi and proboscis yellowish, the latter with short, recurrent terminal portion.

Thorax entirely black, densely clothed with opaque greyish dust; pubescence whitish, bristles black; de. much before the line of the a. sa.; one mpl., with some whitish long hairs. Scutellum like back of mesonotum, with only the b. sct., which are very long and black. Calypters white ; halteres yellowish. Abdomen entirely shining black, with black pubescence and black bristles ; ovipositor shining black, short, about as long as the last abdominal segment. Legs all orange, with the front femora a little darkened on the external side and with two yellowish bristles below. Wings (fig. 83) with short costal bristle; distance between the cross-veins shorter than the length of the hind cross-vein. They are entirely blackish, with hyaline base, in which there is a darkish oblique band extending from the anal cell to the humeral cross-vein. Stigma quite black. Marginal cell with a broad hyaline spot just beyond the stigma, forming a single indentation with the subquadrate spot of the submarginal cell, and, moreover, with a small hyaline spot before the end; submarginal cell with a broad hyaline spot at end. First basal cell without terminal spot; first posterior cell with a broad rounded spot near the base and another South African Trypaneid Diptera. 539 at end. Discoidal cell with a single broad spot in the middle, fused with that in the middle of the third posterior cell; second posterior cell with only one broad indentation, extending to the fourth vein; base of discoidal cell with one hyaline spot fused with the hyaline basal portion of wing. Axillary lobe hyaline, unspotted. Spathulina parceguttata, Becker, 1903, var. parca, Bezzi, 1913. (Pl. XIV, fig. 85.) Well distinguished by the isolated black spot at end of third vein ; in this character it agrees with my acrosticta, 1918, from Durban, being very probably conspecific with it. Numerous specimens of both sexes from Kast London, on the Composite plant Helichrysum, sp. (H. K. Munro). This species, originally described from Egypt, seems to be widely spread over the Ethiopian and Oriental regions, because I now think that my parca is only a variety distinct by lacking the hyaline spot in the middle of the first posterior cell (fig. 85). Spathulina biseuarestina, sp. nov. (Ei OVE ig 288) A typical Spathulina near parceguttata, but distinct by the muck richer wing-pattern, which shows three hyaline indentations in the second and two in the third posterior cell. Both sexes from Pretoria, January 1923 (H. K. Munro). $2. Length of body and wing,3 mm. Occiput black, grey dusted, narrowly pale below.

Marginal cell with two hyaline spots just beyond the stigma; submarginal cell with three, one below and in contact with the first of the two above-named, one below the end of second vein, and one just before the apex, its corner extending into the first posterior cell. First basal cell unspotted ; first posterior cell with a small spot near the base and another larger at end; second posterior cell with three indenta- tions, the posterior one extending with a point into the first posterior cell, and forming thus the lower ray of the terminal fork; discoidal cell with the extreme base hyaline, with one spot near the end and with another very small at lower corner; third posterior cell with two hyaline indentations, one very large in the middle and another smaller before the end. Axillary lobe almost entirely hyaline, only a little infuscated in the middle, near the sixth vein. Spathulina arcucincta, sp. nov.

Legs quite orange, the front femora with strong dark yellowish bristles below. Wings (fig. 86) with short costal bristle; second, third, and fourth veins gradually diverging towards the end; distance between the cross-veins shorter than the length of the hind cross-vein. They are completely black to the extreme base, the black of the base being separated from the rest by a South African Trypaneid Diptera. 54] rather narrow hyaline band, extending from the second costal cell to the base of the discoidal cell. Stigma black. Marginal cell with a broad rounded hyaline spot just beyond the stigma, fused with an equally broad spot in the submarginal cell, and with another much smaller spot near the costa. Submarginal cell, besides the above- named spot, with the extreme base hyaline and with narrowly hyaline end ; first basal cell without spot at end. First posterior cell with a broad rounded hyaline spot near the base, and with a narrow terminal hyaline streak, which forms the terminal hyaline arcuate band in union with the similar spot at end of submarginal cell. Discoidal cell with a small spot at extreme base, another broad rounded one in the middle, and a smaller one on the lower external angle. Second posterior cell with two hyaline indentations, a smaller narrow terminal one, and a larger basal one, resulting from two spots fused together.

Very much like the preceding, distinct only by lacking the upper terminal hyaline spot of submarginal cell, below the end of second longitudinal vein (fig. 90). This character is equally developed in both sexes. Type 392, a single couple of specimens from Matroosberg, Ceres Division, 5000 ft., November 1917 (R. M. Lightfoot). Spathulina hessii, Wiedemann, 1819. (Pl. XIV, fig. 92.) A characteristic species, somewhat variable in wing-pattern, dis- tinct by the yellowish hyaline base of wing. Two female specimens from Hottentots Holland Mts., 4000 ft., Caledon Division, January 1916 (K. H. Barnard); one 9, Kimberley, 1912 (J. H. Power). To Wiedemann’s original description may be added: Occiput black, grey dusted, yellowish below and at border.

Axillary lobe hyaline. Sometimes there are small spots at end of first basal cell and two small hyaline dots, one above the other, in the middle of the first posterior cell, and one hyaline dot near upper outer corner of discal cell. Spathulina hess, var. simplex, var. nov. (els SOD; ste. Sil.) Differs from type form in lacking the outer hyaline indentation of the third posterior cell and in having the ovipositor shorter than the abdomen. The wing-pattern (fig. 91) is more reduced, lacking the additional hyaline spots of first posterior and of dis- coidal cell. One 3g, one 9. MHottentots Holland Mts., 4000 ft., Caledon Division, January 1916 (K. H. Barnard). Spathulina hessii, var. euarestina, var. nov. (Pl. XIV, fig. 93.) Distinct from the two preceding forms in having three hyaline indentations in the second posterior cell. It is also very lke the type species of the genus (tristis, Loew) from South Europe, even this last being perhaps a form of hessvi. Type @, a single specimen from Bethulie, O.F.S8., April 1918 (H. K. Munro). Q. Length of body and wing, 3-5 mm.; of ovipositor, 1 mm. 544 Annals of the South African Museum. Head, its appendages and chaetotaxy as in hessiz; thorax, scutellum, halteres, abdomen, and legs likewise. Wing-pattern (fig. 93) the same, but there is a third hyaline indentation in the second posterior cell, between the two of the preceding forms; third posterior cell without terminal hyaline indentation. No additional hyaline spots in first basal, first posterior, or discal cells. S. tristis, which has also three hyaline indentations of the second posterior cell, is different in having two hyaline indentations and one hyaline spot in the third posterior cell ; the femora are, moreover, distinctly darkened, almost blackish. SPHENELLA, Robineau-Desvoidy, 1830. Even this genus is an artificial one, being distinguished mainly on wing-pattern from the following one. I have omitted reference to it In my previous papers, having overlooked the species pub- lished by myself in Denkschrift. med.-naturwiss. Ges. Jena, 1908, xi, p. 198. The South African species are as follows :— 1. (4) Face, antennae, and femora quite yellowish. 2.

Probably only a variety of the preceding species, distinguished by the quite black unspotted stigma, by the wing-bands destitute of hyaline spots, and by the single fuscous spot along the fifth vein. South African Trypaneid Diptera. 545 From indica, Schiner, it is distinguished by lacking the fuscous tooth at the apical fuscous patch of the wings (fig. 95). Described by me in the female sex from Namaland. JI have seen a female specimen from Pretoria, November 1917 (H. K. Munro). Sphenella nigricornis, sp. nov.

Ensina anceps, Loew, 1861. Wanting in the present collection, all the specimens belonging to the following form. Ensina anceps, var. fasciolata, var. nov. (Pl. XIV, fig. 100.) Distinguished from the type by the want of the third hyaline spot in the marginal cell, or sometimes with only a small dot at its place (fig. 100). One male specimen, Krantzkop, Natal, November 1917 (K. H. Barnard); both sexes, Matroosberg, Ceres Division, 3500 ft., and South African Trypaneid Diptera. 551 Oudebosch, Caledon Division, November—December (R. M. Lightfoot) ; Prospect, Grootfontein (H. K. Munro). Ensina myiopitoides, Bezzi, 1908. (GEN, QIN 289, OIL) Allied with the preceding, but with less differentiated wing-bands, and with a hyaline spot at end of first posterior cell. In this last character 1t agrees with the following species, of which it is perhaps a variety with reduced and variable wing-pattern (fig. 101). One female from Cape, determined by Bigot as Tephritis hottentot, an unpublished name; Gt. Winterhoek, Tulbagh Division, 4500 ft., November, Matroosberg, Ceres Division, 3500 ft., November (R. M.

XIV; fig. 102.) Distinguished by the yellowish hyaline spot of pterostigma ; but the character is variable, one wing having sometimes the spot, while in the same specimen the other wing is without it. Even the Indian species lyncea, Bezzi, 1913, is allied. Cape Town, 1915, (L. Peringuey); Table Mt., February 1919 (R. W. Tucker); Cedarbergen, September 1923 (K. H.

Ensina magnipalpis, Bezzi, 1920. (BIS POVe tics a0") Nearly allied with the preceding, but with a somewhat different- wing-pattern (fig. 104). One female specimen, Kimberley, 1912 (J. H. Power) ; originally described from Durban. Ensina heroglyphica, sp. nov. (elle DQ s0key, 1059.) Distinct from both the preceding species in the more numerous hyaline spots of wings. Type 2 from Cape, without precise locality ; some specimens of both sexes from East London, July 1921 (H. K. Munro). $2. Length of body and wing, 4 mm.; of ovipositor, 0-6 mm. Head, its appendages, and chaetotaxy exactly as in dubia; thorax, scutellum, and abdomen likewise. Legs with more broadly darkened femora. Wings (fig. 105) with the same venation, but with a different pattern. The broad ocellar spots are more numerous and closer together, the two dark bands of dubia being thus not differentiated. The stigma has one definite, rounded, hyaline spot before the end. The costal cells show some hyaline spots along the costa, two of which are larger, and, moreover, a row of small dots along the first vein. Characteristic are the numerous and closely placed hyaline dots, disposed in two irregular rows on each side of the second longitudinal vein. Ensina cribripennis, Bezzi, 1924. (Pl. XV, fig. 106.) Distinct from the three preceding species in having the hyaline spots of the wing much smaller and scattered (fig. 106). 7 Recently described from a specimen from East London in the Paris Museum. South African Trypaneid Diptera. 553 Evristi, Meigen, 1800. The generally accepted name for the present genus is that of Tephritis, but I have followed Professor Hendel in retaining Huribia. The following are the species at present known from South Africa, including those previously placed in Oxyna by some authors :— 1. (2) Pterostigma very small, shorter than high; wing-pattern radiating at end ; only two scutellar bristles : : tuckert, sp. Nov. 2.

(9) Wings with a diffuse reticulation in the middle and with the above-named spot much larger , : : ; : : dissoluta, Loew. Euribia tuckeri, sp. nov. (Pl. XV, fig. 107.) A remarkably distinct species on account of its very short stigma, which is unique among the species of the present genus. On account of this character and of the radiating pattern, one would place the species in the genus Trypanea, but the fuscous reticulation is extended to the base. Type 3, a single specimen from E. Transvaal, Komati Poort, November 1918 (R. W. Tucker) ; named in honour of the discoverer. But I have seen the species also from Madagascar, and thus it seems to be widely spread. g.

Base of wing hyaline to the basal cross-veins, with only one dark spot in middle of the second costal cell. Marginal cell with three broad hyaline spots at base, one following the other and the middle one being larger ; moreover, there is a smaller hyaline spot just before the end. Submarginal cell broadly hyaline at base, with a rounded hyaline spot in the middle, just above the small cross-vein, and with two spots at end, the superior one larger. First basal cell with three, partly confluent, rounded hyaline spots of greater size. First posterior cell with two small spots in middle, one above the upper end of the hind cross-vein, the other in the middle, followed by two spots of greater size placed one above the other, and, moreover, with a broad terminal spot, the blackish pattern being thus radiating ; discoidal cell with three broad hyaline spots ; second posterior cell with three broad spots at border and with two smaller ones in the middle ; third posterior cell with one before the end, and several others, in part confluent, at base.

Even the Indian spiloptera, Bezzi, 1913, seems to be very nearly allied. CampicLossa, Rondani, 1870. Campiglossa perspicillata, Bezzi, 1918. (Pl. XV, fig. 114.) One female specimen, Gt. Winterhoek, Tulbagh Division, 3000 ft., April 1916 (R. M. Lightfoot); Prospect, C.P., October 1922 (H. K. Munro). Camaromyt4, Hendel, 1914. Camaromyia helva, Loew, 1861. (Pl. XV, fig. 113.) One female specimen, Krantzkop, Natal, November 1917 (K. H. Barnard) ; Cape Flats, December 1900 (C. P. Lounsbury).

Characteristic is the hyaline streak along the costa just beyond the stigma, very like that observed in Afreutreta bipunctata, Loew. The hyaline dots at basé of first posterior cell vary in number from one to two. The faint reticulation in the third posterior cell and in the axillary cell is always distinct (fig. 115).

(Gedy DQ vines, IIL 7/2) Among the species with short stigma, this is distinct. by having the first posterior cell broadly hyaline at base, the small cross-vein being thus not included in the terminal black patch and being usually not margined with fuscous (fig. 117). Some specimens from Prospect, November 1922 (H. K. Munro). Trypanea peregrina, var. mundella, var. nov. (Pl. XV, fig. 118.)

Occiput pale yellowish, with a triangular blackish spot above, extending from the neck to the vertex. Frons flat, but rather prom1- nent in profile near the root of antennae, one and one-half times longer than broad, opaque reddish, with whitish sides and blackish ocellar spot; lunula whitish; face and peristomialia yellowish, the latter unspotted. Antennae entirely reddish, shorter than the face ; thira joint rounded at end; arista bare.

Stigma hyaline, distinctly longer than high. The blackish pattern is characterised by the broad prolongation to the basal cross-veins; the costal and marginal cells and the stigma are hyaline, forming a hyaline costal stripe, which is broader in the male than in the female; moreover, the marginal cell has a 564 Annals of the South African Museum. triangular, hyaline indentation before the end. The dark middle stripe of wing is extended only a little below into the discoidat cell, without reaching its middle. In the male the black, rounded “ bulla ” is a little before the middle of the first posterior cell, near the third longitudinal vein, and extending below not beyond the middle of the cell; this “ bulla”? is concave on upper surface of wing and prominent on lower surface, and is, moreover, more intensively black than the surrounding parts. There is a small hyaline spot in the submarginal cell just below the end of the second vein. Apical fork complete; in the middle of the second posterior ceil there are two perpendicular dark rays, another along the hind cross- vein, and one in the discoidal cell, prolonged in the male to the hind border of wing, but not in the female.

Differs from the above description as follows: .The hyaline stripe along the fore border of wing is interrupted by a black, oblique band just beyond the stigma. The first basal cell has a rounded hyaline dot before the small cross-vein, symmetrically placed with that in the base of first posterior cell. The black rays at hind border are broader. The black middle stripe of wing is much broader, extending below into the discoidal cell beyond the middle of the cell, and in the basal part reaching even the fifth vein. The “ bulla” is as in the preceding (fig. 120). Trypanea euarestina, sp. nov. (BL XW, fie. 1215) Very like the preceding bulligera, but at once distinguishable in the male sex by the complete want of the “ bulla.” Type 3g, a badly preserved specimen from Hottentots Holland Mts., 4000 ft., Caledon Division, 1916 (K.

Wings (fig. 121) as in bulligera, but quite destitute of the prominent “ bulla ” of the first posterior cell, and thus the last portion of third vein is quite straight. Even the pattern is very similar, but the stigma is infuscated along the costal border; the dark stripe in the discoidal cell is narrow; the end of the marginal cell is more intensively black than the surrounding parts. Trypanea dentiens, sp. nov. (POV ptieal2 25) Distinct from the three preceding species by the black wing-pattern being more shortened basally, and by the four sct.

The black pattern stops at stigma, with which it is broadly united, and is characterised by the presence of an acute black tooth in the first basal cell, running along the third vein. The stigma is black, with narrowly yellowish base. Just beyond the stigma there are in the marginal cell two hyaline elongate streaks, the anterior of which is larger; submarginal cell with a small hyaline spot just below the end of second vein and with another broader one at end. All the five fuscous rays are narrow and complete, two forming the long terminal fork, two parallel and perpendicular- across the middle of the second posterior cell, and one along the hind cross-vein; moreover, there are two abbreviated rays in the terminal part of the discoidal cell, the basal one more long and oblique, not reaching the fifth vein, on which there is, however, an isolated dark spot. The basal part of the wing is whitish hyaline and quite unspotted ; the hyaline spot in the first posterior cell is small. Trypanea confluens, Wiedemann, 1830. (Pl. XV, fig. 123.)

New Species of Geometridae (Lepidoptera) in the Collections of the South African Museum.—By Louis B. Prout, F.E.S. (With Plates XVI and XVII.) THE species and forms here first made known have been accumulating since the publication of my last paper in these Annals (Vol. XVII, pp. 47-77, 1917). The types—excepting Perizoma artifex basutensis —and all other material unless otherwise specified, are in the South African Museum. Specimens mentioned as being in the author’s collection have been kindly presented by the Museum. The present opportunity is taken to figure also the species of which we were not able to provide the plate contemporaneously with that memoir ; in some cases the type specimens have been sent to Miss Prout for this purpose, in others a paratype or other specimen deter- mined by the author has served as model. Only Eupithecia subcon- clusaria and a few subspecies are now left unfigured. Obolcola cacoctenes Prout (Ann. S. Afr. Mus., XVII, 73) must rank as purely a synonym, as a very serious blunder was committed ; it transpires on re-examination that the specimen is a 2, with the bristles of the frenulum extraordinarily fused and the abdomen lost, and evidently nothing but a large specimen of the variable O. ferrorubrata Walk. Suspram. HEMITHEINAH. 1. NEROMIA STRIGULOSA sp. NOV. (Plate XVII, fig. 10.) 3,27mm.; 9,34mm. Face rose-pink. Palpus white, with strong rosy admixture. Vertex white. Occiput narrowly green. Antennal shaft white, in g stout and furnished with rudimentary pectinations about as in clavicornis Prout (Nov. Zool., xxi, 319), m 2 somewhat tapering. Thorax and abdomen above concolorous with wings, marked with a yellow-white dorsal line or slight ridge as in rubri- punctilla Prout ; pectus white, with a pink tinge in front. Fore and middle legs strongly pink on upper and outer side; hindleg more weakly tinged with pink. Wings shaped about as in rubripunctilla. Forewing with SC? free, 39 580 Annals of the South African Museum. R! about connate, M' closely approximated to R?; light yellow-green, brighter and more yellowish than in the allies; the white irroration more strong, more regularly forming transverse strigulae than in the allies ; costal margin white ; antemedian line obsolete; postmedian faint, from about two-thirds costa, almost parallel with termen ; fringe white.—Hindwing with SC? well stalked in the g, scarcely in the 9, M' closely approximated to R?; similar to forewing, postmedian line rather more proximal, very slightly simuate inward in the middle. —Underside rather paler, costal margin more yellowish, line obsolete. S.W. Africa: Gaub, December 1919 (R. W. Tucker). Allotype 9 in coll."L. B. Prout. 2. MicToSCHEMA SWIERSTRAI TUCKERI subsp. nov. (Plate XVII, fig. 11.) Forewing with distal margin slightly more curved anteriorly than in S. swierstrat Prout (Ann. Transv. Mus., vin, 153), cell slightly longer ; SC! connected by a very short bar with C, R! not stalked; more variegated than the name-type, the median and terminal areas being more blackish, their white boundary lines more decided, some rather conspicuous light-brown shades proximally to the subterminal and (though less defined) near base; antemedian line less excurved be- tween M and SM?.—Hindwing with termen slightly more convex about R°-M!; M?* just separate; similarly differentiated.—Underside with the submarginal band well developed on both wings. S.W. Africa: Otjituo, June 1920 (R. W. Tucker), 1 3. I provisionally treat this as a subspecies, but 1t may prove either an aberration or a related species. 3. HEMISTOLA (?) EREUTHOPEZA sp. nov. (Plate XVII, fig. 17.) 2,20mm. Head whitish, becoming red around the eye and at base of antenna. Palpus short and slender, strongly mixed with red. Tongue vestigial. Antenna bipectinate (only the stumps remain- ing). Thorax whitish, tinged in front with ochreous (discoloured from green ?), otherwise with pink. Abdomen white. Legs pre- dominantly red, especially the first two pairs. Forewing with costal margin straight except at base and near apex, termen oblique, gently curved ; DC? deeply incurved, SC! anastomos- New Species of Geometridae (Lepidoptera). 581 ing at a point with C, SC? not anastomosing, R1 very shortly stalked, R? from very near R!, M! from very near R?; yellow-green ; costal edge red, separated from the ground-colour by an ochreous shade ; fringe flushed with pink.—Hindwing with costal margin rather long, apex and termen rounded; DC? and R? as on forewing; SC? well stalked, M! well stalked ; white, with a tinge of ochreous.—Forewing beneath whitish-green at apex and hind margin and narrowly at termen, otherwise strongly suffused with red; fringe as above. Hindwing beneath nearly as above, but slightly more greenish, at least costally. Orange Free State: Petrusburg, 19th April 1918 (Miss J. Skarp). Supram. STERRHINAE. 4, SCOPULA MONOTROPA sp. nov. (Plate XVII, fig. 24.) @, 25-27 mm. Head and body white, with fine brown-grey irroration, the palpus, pectus and fore- and middle-legs slightly browner, the collar narrowly brownish ochreous. Palpus fairly strong, rather longer than diameter of eye. Tongue rather long and strong. Antenna minutely serrate. Wings appreciably more elongate than in phyletis Prout (Ann. Transv. Mus., 11, 197, t. xu, f. 34) recalling the shape of Leucoxena * lactea Warr. (Nov. Zool., vii, 94).—Forewing white, with a faint tinge of brown and with fine and sparce brown-grey irroration ; cell-dot black, minute; lines brown-grey, the antemedian and postmedian strong except at costa, the median weaker; antemedian from costa near middle, almost straight to three-eighths hind margin or rather beyond ; median well beyond cell-dot, postmedian about 2 mm. from termen, both slightly incurved to costa and still more slightly excurved to hind margin, otherwise parallel with termen; a weak brownish shade just beyond postmedian, a still weaker one at termen, the sub- terminal line between them ill-defined, fairly broad; terminal line dark brown, slightly interrupted, marked with fine black interneural dots, at least anteriorly ; fringe concolorous with termen.—Hindwing * Warren referred that genus to the “ Astheninae,” but it is scarcely more than a subgenus of Scopula, with stronger (though variable) anastomosis of vein C of hindwing—perhaps connected by intergrades. Fawcett (Proc. Zool. Soc. Lond., 1916, p. 731) treats it as equivalent to (Scopula Sect.) Induna Warr., which is quite near the mark. 582 Annals of the South African Museum. rather purer white ; antemedian wanting ; cell-dot minute; median extremely fine and weak, apparently touching the cell-dot; post- median strong except at costa, rather less curved than termen, slightly approaching termen posteriorly ; distal shades obsolete; terminal line nearly as on forewing; fringe white——Underside rather more brownish white, weakly marked; antemedian wanting ; median just discernible ; postmedian stronger, on hindwing nearer termen and parallel therewith ; terminal line and dots not strong. S.W. Africa: Windhoek, January 1920 (R. W. Tucker). Paratype myc oll ee brout: Several specimens, including both sexes, have just now come to hand from other localities in the same region (Tsumeb, Gaub, Nuragas, Otjituo). The $¢ are slightly more brownish in tone and very feebly marked ; antenna bipectinate, with very long branches (the longest about 10 times diameter of shaft); hindleg long and slender, but without spurs. 5. SCOPULA PALLEUCA sp. nov. (Plate XVII, fig. 19.) 3, 24 mm.; 9, 22 mm. Antenna-group of the preceding; the wings—at least in the g—appearing slightly less elongate costally and the face perhaps slightly flatter.

Hindwing beneath rather paler, with conspicuous cell-dot and fine, weak lines. Cape: Dunbrody, May 1915 (Rev. A. Vogt). I do not think this can be a local form of sqwamulata Warr. (Nov. ' Zool., vii, 93), which has also the long and slender hindleg ; apart from the very different aspect (large cell-dots, absence of dark marginal shades, etc.), the antenna, though not in perfect condition, appears to differ markedly, the joints scarcely projecting and the ciliation being shorter (in squamulata 14 or 2, somewhat fasciculate). Costa of forewing more arched than in macrostyla Warr. (Nov. Zool., vu, 92), ground-colour less sandy, distinguished further by the cell-dots and by having less weak markings (except the postmedian).

Hindwing beneath recalling in its purple- grey tone that of O. eprpercna Prout or of Larentia inaequata Walk. ; a rather indistinct, rather thick postmedian line, strongly curved near costa, thence pretty straight, passing just outside the posterior angle of cell; a still more vague subterminal band.

Head and body brown, with a good deal of blackish admixture ; face, palpus, tegulae and tarsi predominantly dark. Forewing brown, with a fleshy or reddish tinge and with copious, coarse, olive-blackish irroration, which condenses to form the not very sharply defined lines and oval cell-spot ; antemedian line at about one-third, bent outward behind cell, then inward, marked with some hoary scales; postmedian from about three-fourths costa, irregularly lunulate, slightly excurved anteriorly, incurved between R8 and M?, accompanied distally by a tolerably complete line of hoary or glaucous-whitish scaling ; fringe weakly spotted opposite the veins. —Hindwing with first line and cell-spot obsolete, postmedian similar to that of forewing, slightly farther from termen.— Underside similarly coloured, becoming whitish at hind margin of forewing; both wings with rather blurred dark postmedian line, the pale scales asta to it weaker than above.

(Plate XVII, fig. 18.) 3, 43 mm. Exceedingly like #. sublimbata Warr. (“ Myrioble- phara’’). Larger, rather more slenderly built, the markings less New Species of Geometridae (Lepidoptera). 595 heavy. Antenna with the typical structure of Hctropis (short paired processes bearing fuscicles of cilia, whereas swblimbata has developed short fasciculate pectinations), the cilia longer than diameter of shaft. Forewing with cell only one-half (in sublimbata over one-half) ; antemedian line apparently less deeply outbent ; postmedian slightly farther from discal ocellus, anteriorly parallel with termen (in sublim- bata curving appreciably inward costally) ; subterminal with longer teeth outward between R? and M?.—Hindwing with postmedian line less strongly incurved in posterior half than in sublimbata ; beneath without the dark longitudinal streak in cell which is often developed in that species. Cape Province: Hottentots Holland Mountains, 4,000 feet, Caledon Division, January 1916 (K. H. Barnard). The type is worn, but quite recognisable. The three species sublimbata Warr., simplex Warr. (“‘ Idiotephra’”’), and paracopa form a closely related group, which looks as though it should be well separable generically from true Hctropis, but unfortunately seems con- nected therewith by various intergrades in respect of the taxonomic characters at present used. All three have the face smooth, the palpus very short (usually less than diameter of eye), the wings rather elongate, almost smooth-margined (smoothest in simplex), the first two subcostals of the forewing coincident, the fovea wanting, the hind tibia not dilated. In Warren’s two species the $ antenna bears pairs of true pectinations (he is hardly accurate in treating these as mere pedicels in s¢mplex, for they are rather longer than the diameter of the shaft) and the cell of the forewing more than one-half. What- ever may be the ultimate fate of Hctropis as a genus, it is pretty certain that Myrioblephara must be merged in it; and sublimbata has not even the structure of typical Myrioblephara. 21. TEPHRINA EXERRARIA sp. Nov. (Plate XVII, fig. 20.) $2, 22-25 mm. Like deerraria Walk., but smaller, with the post- median line of forewing gently excurved in anterior part (in deerraria straight), generally rather thicker but often less sharply defined, accompanied distally by a more conspicuous brown shade than in deerraria;; proximal half of distal area generally rather strongly dark-clouded; in addition, the median shade, which in deerraria is 594 Annals of the South African Museum. generally placed distally to the cell-spot (though very variable), seems in ewerrarva to be always proximal, browner, often obsolescent, anteriorly only marked in fuscous as a spot on hind margin. Cape Province: Clanwilliam, a long series in coll. South African Museum et coll. L. B. Prout. This was submitted to my inspection by the Museum some years ago and passed over as a dwarf race of deerraria, though the constancy of its size arrested my attention ; on account of the postmedian line I think it must be a separate species, or possibly a local race of dis- putaria Guen. 22. TEPHRINA (?) DIARMODIA sp. nov. (Plate XVII, fig. 21.) 2, 26 mm. Face prominent, rounded, without projecting cone. Palpus moderate (antennae lost).

(Nov. Zool., vi, 306); praesubterminal dark band far beyond the postmedian, continuing the distal half of the forewing band, and curving slightly so as to reach hind margin close to tornus ; slight macular shading midway between postmedian line and this band ; pale subterminal shade broadening posteriorly.— New Species of Geometridae (Lepidoptera). 595 Underside with no black irroration, cell-marks weak, lines almost obsolete ; both wings with ill-defined praesubmarginal band.

Frontal prominence with the vertical suture strong, the knob below undeveloped. Antennal cilia- tion in g scarcely as long as diameter of shaft. Forewing with termen perhaps even more faintly sinuate in anterior half than in nubilata Warr. ; ochreous light-brown, rather strongly irrorated with grey, which forms an appreciable, though not sharply- defined, darker triangular cloud distally, commencing in a point at termen close behind SC, at hind margin occupying half the wing-- length; costal margin slightly less irrorated, the commencement of the lines here showing as outwardly oblique brown marks, the median nearer to the postmedian than to the antemedian ; markings otherwise almost entirely obsolete ; a faintly dark, somewhat elongate cell-mark indicated, also a slight pale shade from apex, bounding the grey border proximally, and an ill-defined dark spot or streak between R3 and M! on the proximal edge of the grey border; a weak dark terminal line ; fringe slightly mottled, traversed by two fine whitish lines, the stronger one at base, the slighter in middle.—Hindwing less strongly irrorated ; a small blackish cell-dot ; a brown postmedian line from about two-thirds costa, projecting outward to a point at R1, then slightly sinuous to hind margin at three-fifths, where it is marked by a dark, distally white-edged dot; distal dark shade weak and narrow ; termen and fringe nearly as on forewing.—Under- side, especially of hindwing, more ochreous, on the forewing becoming whitish-mixed posteriorly and with the grey terminal shade indicated anteriorly and continuing very narrowly to SM?; both wings with a slightly reticulated appearance and with a moderately conspicuous dark cell-dot (on forewing slightly elongate), termen and fringe as above.

SEMIOTHISA BRONGUSARIA EXOSCIODES subsp. nov. 3, 28 mm. Slightly narrower-winged than typical brongusaria Walk., hindwing appreciably more bent at R’, showing an approach towards the shape of S. parallacta Warr. (Nov. Zool., iv, 112), ete. Ground-colour as in the least ochreous (more whitish) brongusaria, with grey irroration which leaves a paler area on the forewing proxim- ally to the postmedian line and forms on both wings a rather definitely darkened distal area. Forewing with median line crossing the cell- dot ; oblique pale subapical streak narrow, the two dark dots in front of the angle of the postmedian line (before and behind SC*) rather strong, the pale tornal patch small and ill-defined, the dark spot proximal to it not strong, divided into two by the submedian fold. Hindwing with the dark border traversed by a fairly distinct whitish subterminal line. S.W. Africa: Grootfontein (R. W. Tucker). On the strength of a single specimen, the status of this form is largely conjectural ; differences of shape, even when only slight, are very generally specific, while on the other hand they may conceivably prove only teratological. On the whole, it seems best to regard the specimen as representing a form of the extremely variable brongusaria, with which it agrees in venation, non-dilated hind tibia, etc., and which is abundant in the Cape Province and 8.E. Africa. It has unfortunately been decided that the name Semiothisa Hib. - is prior to Macaria. 25. OBOLCOLA PULVEREA (Prout) ab. scoTozoNA ab. nov. This species, doubtfully described by me from a @ with rather exceptional venation as an aberrant Sicyodes (Ann. 8. Afr. Mus., XVII, 64) and now figured (Plate XVII, fig. 23) proves to be an Obolcola ; $3 from the type locality (March and April) agree with it except in their smaller size and more sharply expressed cell-dots. Among them is a remarkable aberration with the cell-spots enlarged (that of fore- wing ocellated) and with a continuous subterminal dark band above and beneath, strongest and most solid on forewing above: ab. scotozona ab. nov. The present occasion may be taken to correct an unfortunate erratum (tom. cit., p. 65). The paragraph at the end of No. 25 (Sicyodes subochrea), commencing “ A damaged 2”’ is out of place and belonged at the end of No. 24, pulverea, though I now think the New Species of Geometridae (Lepidoptera). 597 specimen in question is more likely to belong to petronaria ab. aliena Prout—treally too worn to make out.

Mycetophilidae and Bibtonidae (Diptera) in the Collections of the South African Museum.—By F. W. Epwarps, B.A., F.E.S. (With 3 Text-figures.) (Published by permission of the Trustees of the British Museum.) THE material dealt with in the present paper was sent for determina- tion by the late Dr. L. Péringuey, who kindly allowed the writer to retain duplicates (where available) for the British Museum. Although small, and not in the best preservation, the collection has proved remarkably interesting, and the results of its study lead one to hope that future collecting in the Cape Province will reveal many more new and interesting forms. The occurrence of a species of the genus Heterotricha, hitherto known only from Baltic Amber, is worthy of special note. The genera Dziedzickia and Acrodicrania are also recorded from Africa now for the first time. Famity MYCETOPHILIDAE. Scrara Mg. Sciara stigmatopleura, sp. n. M’fongosi, Zululand (W. E.

Vertex much more extensively dark. Mesonotum with three broad and more or less confluent blackish-brown stripes, though the scutellum and postnotum remain entirely ochreous. Hypo- pygium ochreous, except for the extreme tips of the claspers, which are black. Claspers very large, oval, constricted on the inner side imme- diately before the tip, which has a dense tuft of short black bristles facing inwards. Length of body, 4-4-5 mm. ; wing, 4-4-8 mm. This distinctively coloured species is nearly allied to S. flavoscutellata Hdw. (Hast Africa), which has the postnotum as well as the scutum black in both sexes. Sciara capensis, sp. N. Cape Town Museum Grounds; 1 3, 5 Q, reared from larvae collected 11.vi.1914, pupated 4.vil.14, flies emerged 12.vii.14 (K. H. Barnard). 2. Head of the ordinary size. Vertex somewhat shining, black, Mycetophilidae and Bibionidae (Diptera). 603 considerably swollen. Face greyish. Ocelli equal in size, in a sub- equilateral triangle. Eyes moderately pubescent, separated by about the width of one facet; bridge four facets wide in the middle, but narrowed to a single facet in width close to the main portion of the eyes. Palpi short, black, the three visible segments practically equal in length and scarcely twice as long as broad. Antennae uniformly black, with short pale pubescence ; flagellar segments all equal in length and a little over one and a half times as long as broad.

Pleural membrane ochreous. Hind margins of tergites narrowly pale. Sixth and seventh segments well developed. Ovipositor black, second segment of lamellae oval. Legs rather stout, blackish brown, front coxae and femora somewhat lighter. Tibial spurs blackish, about twice as long as the tibial diameter and about one-third as long as the first tarsal segments. First tarsal segment on front legs one-half, on hind legs one-third as long as the tibia. Hind tibia without apical comb. Claws simple ; empodia and pulvilli short. Wangs with strong smoky tinge, cells C and R1 blackish. Sc not quite reaching base of Rs. Branches of M and Cu bearing macrotrichia. &1 ending exactly above fM, of the same length as Rk.

Cul with the apical half obsolete, the basal half faint. Length of body, 2-5 mm.; wing, 2-2 mm. 604. Annals of the South African Museum. This is a rather well-marked species, on account of the unusually narrow ocular bridge, and the reduced venation of the male. Although the latter feature may not be constant, it is paralleled by S. semialata Edw. (England) and S. beformis, Lundbeck (Greenland). Sciara barnardi, sp. n. Hottentots Holland Mts., Caledon side, 4,000 ft., Jan. 1916 (H. K. Barnard) ; 2 @. 2. Head unusually small, not more than half as broad as the thorax. Vertex dull black, very much swollen. Ocelli close together in a flattened triangle. Eyes densely hairy; the narrow portions just touching, four facets wide. Labium black, slightly more produced than usual. Palpi entirely black and rather long ; the first two of the visible segments each about twice as long as broad, the third nearly four times as long as broad. Antennae entirely black; flagellar segments subequal, not quite twice as long as broad; pubescence very short. Thorax entirely dull black, with a slight grey shimmer in some lights, three narrow lines of intenser black on the scutum. Mesonotal bristles distinct, black; acrostichal in about two rows, dorso-central in about four rows. Scutellum with short black bristles, about six on the margin rather longer than the rest. Pleurae bare. Abdomen dull black, with rather long and conspicuous black pubes- cence. Sixth and seventh segments well developed. Terminal lamellae of ovipositor rather elongate oval. Legs entirely black, the coxae dusted with grey. Tibial spurs reddish, very short, hardly longer than the diameter of the tibiae. First tarsal segment on all the legs about two-fifths as long as the respective tibia. Hind tibia with a distinct black apical comb. Empodia and pulvill well developed, not much shorter than the claws. Wings blackish, some- what darker towards the anterior margin. Costal cell distinctly broadened in the middle. Sc fading out gradually, fairly distinct to about the middle of R. 1 a trifle shorter than R, and ending almost directly above fM. Branches of media parallel, slightly shorter than the fairly distinct petiole. No macrotrichia on M or Cu. Cuscarcely half as long as the first section of MW. M2 ending below the tip of Rs. Halteres black, the extreme base of the stem lighter. Length of body, 4:5 mm.; wing, 5:2 mm. In some respects, notably the small head, the shghtly produced labium, the widened costal cell, and the distinct hind tibial comb, this species shows a distinct approach to the South American genus Mycetophilidae and Bibionidae (Diptera). 605 Rhynchosciara. I am unable to identify it with any of the recorded African species, several of the descriptions of which are entirely inadequate. A third specimen taken at the same place and time is rather smaller, and has the abdomen dark brown instead of black, but almost certainly belongs to the same species. HETEROTRICHA Lw. Heterotricha (?) relicta, sp. n. (fig. 1). Montagu, Cape Province, x.1917 (EK. P. Phillips); 3 3, 1. 39. Head dull dark greyish, pollinose, clothed with a rather long and coarse whitish pubescence. Hyes large, emarginate, with a Fic. 1.—Heterotricha relicta, sp.n. a, wing; 6, ovipositor from beneath ; c, hypo- pygium from above, ninth tergite and anal segment removed and shown separately (d). narrow supra-antennal portion 3-4 facets wide, the pair of narrow projections not forming a complete bridge, but separated by about the width of two facets. Ocelli equal in size, separated by nearly twice their breadth, in a very flat triangle. Palpi rather dark brownish, slender, of three distinct segments (apart from the palpiger) each segment a little over three times as long as broad, the terminal one rather longer and more slender than the others. Antennae with the scape and most of the first flagellar segment ochreous, remainder 606 Annals of the South African Museum dark brown. Flagellar pubescence dense, even, about half as long as the diameter of the segments. First flagellar segment about five times as long as broad, the succeeding segments each a little shorter than the last; penultimate about twice as long as broad, terminal rather longer, bluntly pointed. Antennae of 9 slightly shorter than those of g. Thorax dull dark grey, heavily pollinose; mesonotum with coarse pale yellowish pubescence, mixed with some longer pale hairs and arranged in definite acrostichal, dorso-central and lateral stripes. Scutellum with similar clothing to that of the mesonotum. Pleurae bare, the sutures between the different portions scarcely indicated. Pleurotergites flat, not prominent as in most Myceto- philidae, with about ten long pale hairs. Abdomen blackish, paler ventrally, faintly shining, rather densely clothed with pale yellowish pubescence. Seventh and eighth segments shortened, but not re- tracted, the membrane separating them from the sixth and ninth quite short. Hypopygium small and inconspicuous; ninth tergite rather large and rounded ; claspers simple, notched apically. Ovi- positor also short and inconspicuous, turned downwards and largely hidden beneath the ninth tergite ; no chitinous spermathecae. Legs with the coxae and femora pale ochreous, trochanters black-marked, tibiae brownish, tarsi blackish. Coxae and femora pale haired. Tibial spurs black, two to three times as long as the diameter of the tibiae ; all tibiae with short setae, about half as long as the tibial diameter. Hind tibiae with a rather indefinite apical comb. First segment of front tarsi about three-fifths as long, of hind tarsi one-half as long as the respective tibia. Coxae moderately short, the front pair as long as the others. Hmpodia broad and almost as long as the short simple claws. Wings hyaline, veins all dark; venation as figured. Mem- brane with numerous curved macrotrichia, which are uniformly dis- tributed over practically the whole surface, but more densely crowded just round the tip. Microtrichia very minute, only just perceptible under a magnification of 80. Halteres ochreous, knob somewhat darkened. Length of body, 3 mm.; wing, 3-5 mm. The genera Hetcroiena Lw. and Palaeoheterotricha Meunier are both very imperfectly known, each being based on a single fossil species from Baltic Amber. Since no living representative of the group has hitherto been described, the discovery of one existing in South Africa is of no little interest. According to the information provided by Meunier, in the fossil Heterotricha R1 ends before the level of the base of the median fork, the costa extends far beyond the Mycetophilidae and Bibiondae (Diptera). 607 tip of Rs, and 7m is long, whereas in Palaeoheterotricha the costa stops short at the tip of Rs, R1 ends well beyond the level of the base of the median fork, and r—m is very short. In the new species R1 is long, as in Palacoheterotricha, the costa extends slightly beyond the tip of Rs, and r—m is long, as in Heterotricha. ‘The living form therefore appears to be intermediate between the two fossil forms, and suggests that all three might be included within the same genus; the im- portant character common to all three being the origin of Cul from M instead of from Cuw2. Meunier referred Heterotricha to the Sciaridae, though Enderlein, in his later paper on the classification of this group, considered it as belonging to the Mycetophilinae. In the character of its eyes, how- ever, as well as in the general features of its venation, the recent form certainly seems to be closer to the Sciaridae, and could not, in my opinion, be included in the Mycetophilinae. The form of the genitalia, however, especially those of the female, differs from that of most of the Sciaridae ; and the vestiture of the thorax and abdomen, as well as the abbreviated costa, is reminiscent of the Lestreminae, from which group it would be excluded by the strongly developed tibial spurs. DziEpzicki1a Joh. Dziedzickia nitida, sp. n. Cape Town, vii.1916 (R. M. Lightfoot) ; 1 9. 9. Head shining black, almost bare. Ocelli in a straight line, rather more widely separated from one another than the lateral pair are from the eye-margins. Hyes very slightly emarginate above the level of the base of the antennae. Palpi short, dark brown. Antennae blackish, scape light brown. First flagellar segment slightly over twice as long as broad, second a trifle shorter, third rather shorter than the second, fourth and following segments each a little broader than long. Thorax shining black dorsally, pleurae ochreous brown. Mesonotum with black bristles, those at the sides rather long, those forming the usual three dorsal rows shorter. Scutellum with six bristles, rather slender and irregularly arranged. Abdomen ochreous brown, somewhat shining, the posterior margins of the tergites dark brown ; cerci short, slender, brown. Legs with the coxae, trochanters and femora uniformly ochreous, tibiae brownish ochreous, tarsi dark brown ; tibial spurs pale. On the front legs the first tarsal segment is about three-fifths as long as the tibia and twice as long as the second segment ; the tarsi are not or only very indistinctly thickened. The 608 Annals of the South African Museum. fine tibial setae not arranged in definite rows ; spines black, about as long as the diameter of the tibiae. Hind tibiae without apical comb. Empodia well developed. Wangs with a slight and uniform brownish tinge. Venation as in D. marginata, except that Rs is slightly more curved and rather nearer to R1, and the base of the fork of Cu is only very slightly before the base of r-m. MHalteres with pale stem and brown knob. Length of body, 4mm.; wing, 4 mm. The occurrence of this rather distinct European and North American genus in South Africa is of considerable interest. The new species is obviously closely allied to the European form, but differs in the shining head, colour of abdomen and halteres, and in the form and proportions of the front tarsal segments. Mycomyia Rond. Mycomyia (s. str.) lightfooti, sp. n. (fig. 2). Oudebosch, Caledon Division, xii.1920 (R. M. Lightfoot); 1 3. 3. Head blackish grey, scarcely shining, with fine dark pubescence. Palpi short, blackish. Antennae with the three basal segments brown, the remainder black. First flagellar segment a little over twice as long as broad, next five segments each about half as long again as broad, remaining eight segments from twice to three and a half times as long as broad, gradually becoming more slender towards the tip of the antenna. Thorax uniformly dull blackish brown dorsally, humeri and pleurae ochreous. Mesonotum with three double rows of bristles on the disc, these bristles mostly fine and short. Scutellum with only two strong bristles, which are very widely separated and placed quite near the sides on the apical margin. Abdomen uniformly blackish brown above, lighter below. Hypopygium with two pairs of rather elongate appendages, one very slender, slightly hairy throughout, the other broader, hairy only on the slightly expanded tips. Legs light brownish, trochanters, tibiae and tarsi darkened. As in all members of the genus known to the writer the fine tibial setae are arranged in conspicuously regular longitudinal rows, the hind tibiae have a dis- tinct apical comb, and the empodia are absent. Tibial spurs black. Front legs long and slender, the first tarsal segment slightly longer than the tibia. Middle coxae with a slender, forwardly projecting curved spine, which is not quite half as long as the coxa itself. Hind coxae with a conspicuous posterior row of long bristly hairs. Wangs Mycetophilidae and Bibionidae (Diptera). 609 with a slight and uniform greyish tinge, devoid of markings. Venation: Sc ending in the costa just before the apex of the small cell, which is almost rectangular and about twice as long as broad. Stem of median fork about one-fourth shorter than the lower branch. Base of cubital fork slightly beyond base of the stem of the median fork. Anal vein reaching to middle of cubital fork. Halteres with pale stem and brown knobs. Length of body, 4 mm.; wing, 4 mm. This species differs from all those at present described from Africa in its entirely unmarked wings.

Péringuey) ; 2 3,19. Head dark brown with black bristles. Antennae with the first three segments ochreous, the remainder blackish ; flagellar segments in both sexes approximately equal in length and about as long as broad. Palpi and the rather broad flat labella pale yellowish. Ocelli equal in size, in a straight line, the laterals almost but not quite touching the eye-margins. Thorax dull ochreous brown, scarcely 610 Annals of the South African Museum. shining, the mesonotum with faint indications of three darker stripes ; pubescence pale, bristles blackish. Scutellum with four long black bristles, the middle pair a little further from one another than from the lateral pair. Pleurotergites (lateral lobes of postnotum) with a patch of long black hair. Abdomen ochreous brown ; tergites 2 and 3 with dark brown apical bands, broadened at the sides ; tergites 4-6 almost entirely blackish brown, at least in the male. Hypopygium ochreous, the claspers densely set with short black spiny bristles. Legs uni- formly ochreous, only the tarsi somewhat darkened; tibial spurs pale; spines black, not very regularly arranged, averaging twice the diameter of the tibiae in length. Mid tibiae with two long spines almost ventrally placed, hind tibiae with none. No hind tibial comb. Eupodium distinct, about as long as the claws. Wings with a slight brownish tinge, somewhat darker round the tip, and with a slight brown shade beneath the curve of Cu2. Venation almost exactly as figured by Skuse for A. atricauda, the only noticeable difference being that Sc2 is a trifle further from the tip of Scl. Halteres light ochreous. Length of body, 3-3-5 mm. ; wing, 3-3°5 mm. This is the first African species to be discovered of this genus, which proves to have a wide distribution, species having been reported from India and South America as well as from Australia. The position of the ocelli in the Australian species is not clearly indicated by Skuse ; if his expression “in a straight line on the front’ means that the laterals are well removed from the eye-margins, this will constitute a rather important distinction between the Australian and African species.

Antennae of 9 as long as the head and thorax, basal flagellar segments about one-third longer than broad, remainder as long as broad; antennae of ¢ slightly longer than those of the 2. Scape ochreous, flagellum blackish brown. Palpi brownish. Bristles black. Lateral ocelli narrowly separated from the eye-margins. Thorax light ochreous ; the mesonotum with a pair of very large oval shining black patches, laterally placed on the Mycetophilidae and Bibiomdae (Diptera). 611 posterior two-thirds, somewhat approximated behind and fading out just before the scutellum, the ochreous area between them about half the width of the scutellum ; some specimens also show traces of a double median brown stripe extending from the front margin of the mesonotum to about the middle. Scutellum ochreous; postnotum brownish, darker posteriorly, the prominent pleurotergites shining black. Mesonotal bristles black, those on the lateral margin very stout ; in the disc are some rather long pale hairs mixed with the bristles. Scutellum with four strong black marginal bristles, almost equidistant. Pleurae ochreous, with a slight whitish shimmer in some Fie. 3.—Leia stigmatica, sp.n. a, hypopygium from above ; 6b, from beneath ; c, aedoeagus. lights; subalar knob dark. Abdomen with tergites 1-4 mostly ochreous brown, with broad but rather ill-defined lateral blackish- brown stripes, which in some specimens tend to broaden out just before the apices of the segments and may form narrow transverse subapical dark lines. Sternites 1-4 uniformly ochreous. Segments 5 and 6 almost uniformly blackish brown ; hypopygium and ovipositor ochreous. Legs ochreous, unmarked, only the tarsi darkened. Tibial spines black, spurs brownish. Hind tibia with a rather indefinite comb of black bristles. Wings with a slight uniform brownish tinge, without markings; veins dark brown; 7-m equal to A1 in length or very slightly longer. Halteres very short, pale ochreous. Length of body, 4-5 mm.; wing, 4-5 mm. This species is nearly allied to L. notabilis Edw. (British East Africa), differing in the markings of the abdomen and the unmarked hind femora. The British Museum possesses another (undescribed) species of the same group from Natal, also representatives from the Oriental and Neotropical regions. 41 612 Annals of the South African Museum. Leia (Rhymoleia) maculicoxa (Enderlein). East London, July 1914 (R. M. Lightfoot); 1 2. The discovery of this species in South Africa, assuming it to be correctly determined, forms an interesting extension of its known range ; previous records have been from the Seychelle Is. (Enderlein) and Ceylon (Brunetti and Edwards). In the Cape specimen there is no trace of a dark subapical wing fascia, and the branches of the media are rather less convergent apically than in the other specimens I have examined. It is unfortunate that a male is not available from the Cape at present; possibly the structure of the hypopygium might prove it to be distinct. Mycrtopuita Mg. Mycetophila lineola Mg. Cape Town, 1915 (L. Péringuey) ; 1 2. This common European species has already been recorded by me from East Africa. The present specimen agrees in hypopygial structure and in all other respects with typical British examples of the species. Dexopsis Skuse. Delopsis seychellensis (Enderlein). M’fongosi, Zululand (W. E. Jones); 1 9. The abdomen is lighter in colour than in Enderlein’s types, but this is a variable character in several species of this group, and until a male is obtained this specimen can only be referred to D. seychellensis. The second abdominal segment shows the two long ventral bristles characteristic of the genus. This is the second species of the genus to be recorded from the African continent. Famity BIBIONIDAE. Brsio Geoftr. Bibio melanogaster Wiedemann. Krantzkop, Natal, 11.1917 (K. H. Barnard) ; 2 g,1 9. I identify these specimens with some doubt, owing to certain small Mycetophilidae and Bibionidae (Diptera). 613 divergences from Wiedemann’s description. The pubescence is not entirely greyish, but is pale only on the under side of the head, the sides of the thorax, the whole abdomen and the front and mid femora ; while it is black on the eyes of the male, the mesonotum in both sexes, the hind femora, and all the tibiae and tarsi. In the female the pronotum and scutellum are black, as well as the pleurae, but the mesonotum shows no trace of the median blackish line mentioned by Wiedemann. All the tibial spurs are reddish in both sexes, those on the hind legs being rather slender, the tips somewhat rounded. The smaller spine of the front tibiae is well developed, about half as long as the larger one. Bibio birudis Walker. Illovo, 14.v1.1919 (H. W. Bell-Marley); 3 2. Krantzkop, Natal, xi.1917 (K. H. Barnard); 1 9. 3g. The males agree well with Walker’s type in the British Museum, and exhibit the following characters :—Colour uniformly black, except for the usual pale brownish marks on the humeral angles, above the roots of the wings, and on each side of the scutellum. Pubescence of head, thorax and abdomen rather long, dense and black, that of the legs also all black. Hind femora moderately swollen (less so than in B. melanogaster), their greatest diameter rather less than the greatest diameter of the much swollen hind tibiae. Venation practically as in the allied B. hortulanus Linn. 2. This sex has not hitherto been described. The specimen recorded above, which probably but not quite certainly belongs to this species, resembles B. afer Lw. and B. pyrrhonotus Speiser in having a red mesonotum and black legs, but differs from the former in its black abdomen and from both in its red pleurae. Head narrow, but not particularly elongate, shining black. Pronotum reddish brown, marked with black in the middle and at the sides. Mesonotum with fine reddish pubescence (not black as in the g, and in both sexes of B. melanogaster). Scutellum black, with short reddish pubescence. Abdominal pubescence mostly black, but mixed with some paler, especially at the sides and beneath. Coxae and tibial spurs dull reddish, the hind tibial spurs rather stouter than in B. melanogaster, and bluntly rounded at the tips, the inner slightly longer than the outer. Hind tibia not swollen. Wings dark brown, darker towards the anterior margin, the stigma still darker. Venation as in B. melano- gaster. 614 Annals of the South African Museum. Bibio longirostris Rondani. Syn. B. monacanthus Loew. Cape Town, Sept. 1913 (G. Péringuey) ; 4 9. There is no statement in Rondani’s short diagnosis which conflicts with Loew’s more detailed description, and I therefore suggest the above synonymy and adopt the earlier name. It is worthy of note that the hind tibial spurs are very broad, rounded at the tips, and equal in length ; the costa is produced conspicuously beyond the tip of Rs, much more so than in the hortulanus group. Bibio lightfooti, sp. n. Kraaifontein, Cape Province (R. M. Lightfoot); 4 3, 2 9. g. Uniformly shining black, except for the reddish tibial spurs and the yellow halteres. Pubescence of eyes black, of thorax, abdomen and legs uniformly whitish ; moderately long but not very conspicuous. Rostrum scarcely produced beyond the lower margin of the eyes. Femora somewhat swollen, especially the front pair. Tibiae all slender, the front pair with only one distinct spine. Spurs of hind tibiae equal in length, slender, the tips somewhat rounded. Hind tarsi slender, the first segment about half as long again as the second. Wings milk white; anterior veins brown; stigma pale brown; posterior veins milky. Venation: costa reaching consider- ably beyond the tip of Rs ; m—cu oblique and placed weil beyond the fork of M. Hypopygium very small. 2. Head shining black, scarcely longer than broad, the rostrum and labium together bemg shorter than the eyes; ocellar tubercle prominent and close to the neck. LHyes distinctly hairy. Pronotum black in the middle, its sides and also the proepimera ochreous. Mesonotum with short pale pubescence, shining black, the sides rather broadly yellow. Scutellum black; postnotum blackish brown. Pleurae ochreous; mesosternum black. Abdomen blackish brown above, pale beneath, with short pale pubescence. Legs bright ochreous ; femora darkened at the tips on the upper surface ; mid and hind tibiae with rather narrow black apical rings; tarsi black except on the basal half of the first segment. Hind tibial spurs broader than in the ¢. Wings asinthe g. Halteres pale yellow. Length of body, 3-4-5 mm. ; wing, 4-5 mm. Apparently nearly allied to B. breviceps Lw., differing in the faint stigma and the light-coloured legs of the 2. Mycetophilidae and Bibionidae (Diptera). 615 Bibio turnert, sp. n. Mossel Bay, Cape Province, vi.1921 (R. E. Turner); type 9 in the British Museum. Cape Town, ix.1913 (R. M. Lightfoot) ; paratype 2 in the South African Museum. 2. Differs from B. lightfooti as follows :—Head longer, almost twice as long as its greatest breadth across the eyes, the increase in length being chiefly in the basal part. Ocellar tubercle less prominent and distinctly removed from the neck. LHyes less conspicuously hairy. Pleurae darker. Hind femora dark above for quite half their length. Stigma rather dark brown and quite conspicuous, especially in the type. In spite of the conspicuous difference in the shape of the head, I am not altogether satisfied that this is not a mere variety of B. lightfooti, and it is indeed possible that both may be forms of B. breviceps. Further collecting will solve the problem. Puecta Wied. Plecia ruficollis Fabr. M’fongosi, Zululand (W. E. Jones); 2 g, 2 9. Ditopyus Mg. Dilophus capensis, sp. n.

Front tibiae with a rather irregular and oblique row of four spines slightly beyond the middle ; eight or nine apical spines. Hind tibiae and tarsi slender, the first tarsal segment nearly twice as long as the second. Wings milk white, stigma conspicuous and dark brown, costal cell also slightly darkened. Anterior veins dark brown, posterior veins milk white. Venation as in D. febrilis. Halteres with brownish stem and black knob. 616 Annals of the South African Museum. . Head shining black, nearly twice as long as its greatest breadth, the rostrum (excluding the labium) about as long as the bare eyes. Ocelli well separated, not placed on a distinct tubercle. Thorax shining black, pleurae blackish brown, propleurae and sides of pro- notum conspicuously orange. Abdomen shining blackish. Legs with the coxae and femora orange, trochanters and tibiae brownish orange, tarsi almost black. Front coxae extremely large, both longer and stouter than the femora. Front tibiae with the four spines placed slightly before the middle of the tibia, larger and stouter than those of the male, and also more regularly and less obliquely placed. Wings with the stigma larger and darker than in the male, the membrane on the basal two-thirds slightly clouded with brown. Venation and halteres as in the male. Length of body, 4-4-5 mm. ; wing, 3-5-4 mm.
