(353) 5. On some South African Ichneumonidae in the Collection of the South African Museum. By CLAUDE MORLEY, F.E.S., F.Z.S., etc. Author of Iclmeumonologia Britannica, A Revision of the Ichneumonidae, etc. Part I. THERE has recently been forwarded to me from the South African Museum a small collection of Iclmeumouidae for determination and description. It consists of 136 specimens, distributed as follows among the five subfamilies of these parasitic Hymenoptera : Ichneu- nioniuae, 32 specimens, comprising 23 species, of which 4 were already described ; Cryptinae, 32 specimens, comprising 19 species, of which 5 were described ; Pimplinae, 29 specimens, comprising 19 species, of which 12 were already described ; Tryphoninae, 9 specimens, comprising 7 species, of which 5 were already described ; and Ophioninae, 34 specimens, comprising 19 species, of which 11 were already described: giving the total of 87 species, of which no more than 37 had previously been known, and several of these from Europe only. These have all been compared by Dr. L. Periuguey with the types of 92 South African species in that Museum, described by Peter Cameron, and found by the former to be distinct. I am. not aware that anything in the form of a bibliography of the African Ichneumonidae has yet been attempted ; and it may be well to here indicate where students of these insects should turn for descrip- tions of their captures. This is in so scattered a form that the follow- ing must be regarded as no more than the works entering my head as I write. First, in the 4th volume of Lepeletier's general work on Exotic Hymenoptera, Histoire naturelle des Insectes, Hymenoptcres, we have a good many species superficially sketched by Brullu in 1846 ; Lucas added others in his Exploration Scientifique de 1'Algerie, Zoologie, in the same year. G-ucrin Meneville extended our know- ledge in Lefebre's Voyage en Abyssmie in 1848. Next Holmgren brought forward several kinds in his general account, Eugenies Resa Insect, of 1868 ; and Dr. Taschenberg described several Ophionides in Zeits. Ges. Nat, 1875, p. 436. Fred. Smith added others in the 25 354 Annals of the South African Museum. Eodriguez Expedition in Ann. Nat. Hist. 1876, p. 449 ; and Saussure beautifully figured several plates of them, but with no description, in Grandidier's Histoii-e de Madagascar in 1890. Saussure also added a few kinds in Distant's Naturalist in the Transvaal in 1892. Kriech- baumer described some collected by Dr. Brauns in Berl. Ent. Zeit. 1894, p. 30, etc. ; cf. also Zeits. Hym.-Dip. 19()1 for more by the same author. M. 1'Abbe Berthoumieu published others from northern Africa in Revue Scieutifique du Bourbonnais in 1894, p. 181, and W. F. Kirby from the Congo in Ann. Nat. Hist. 1896, p. 257. Prof. Krieger brought forward others in Berl. Ent. Zeit. 1894, p. 304, and Sitz. Nat. Oes. Leipzig, 1899, p. 113. Jacob added something in Eevue Eusse d'Entomologie, 1907, p. 7. We have sevei-al somewhat indifferently described species by Szc'pligeti in Ann. Mus. Nation. Hungarie, 1903 and 1905 ; iii the Bull. Mus. Paris, 1907, p. 139 ; and in his account of the material collection by Sjostedt's Kilimaiijaro-Meru Expedition ii, 8, 1910. Other worts are Gribodo Anni Museo Civico Geuova, 1879, p. 345 ; du Buysson in Annales Societe Entomologique France, 1897, p. 352 ; Cameron in Eecords of Albany Museum, 1904, p. 146, and 1905 ; Zeits. Hym.-Dip. 1905, p. 343 ; Trans. S. African Phil. Soc. 1905, and 1906 ; Annals S. African Museum, 1906, pp. 81-182 et 1907, pp. 203-225, and Trans. Linn. Soc. 1907, p. 80 ; Schulz has added a little in Spolia Hym. 1906, and Zool. Annalen of 1911. Mr. S. A. Neave has recently collected somewhat extensively in Central Africa, and much of his material, along with Mr. W. L. Distant's collection from the Transvaal and other material in the British Museum, has been monographed by me in the four parts of Eevision of the Ichneumonidae during 1912-15 ; and I also worked out Scott's material from the Seychelles Islands in the Proc. Linn. Soc. in 1912, ii. p. 169. But the only account of considei'able extent on the subject is Dr. J. Tosquinet's " Ichneumonides d'Afrique " in Menioires Soc. Ent. Belgique, 1896, pp. 1-430 : a complex work. The types of the new species are, unless otherwise mentioned, in the South African Museum at Cape Town. In the descriptions I have attempted to give a superficial idea of the facies in the first few words. CLASSIFIED CATALOGUE. ICHNEUMONIDAE. ISCHNOJOPPA, Krch. ICHNEUMONINAE. luteator, Fab.

A monograph of this Tribe has recently appeared in my Revision, part iv, published by the British Museum in 1915. lu it is enumerated the EUJOPPA, Szepl. Term. Fiiz. 1900, p. 282. Essential Characters. Abdomen parallel-sided, narrower than thorax; second segment elongate. Labruui concealed beneath clypeus. Meso- notuni evenly punctate ; clypeus not apically produced, nor colour metallic. Segments both aciculate and laterally angularly produced ; flagellum of $ centrally dilated and of $ serrate. A single species of this genus only has hitherto been described, and that from Brazil ; but the following fills all the necessary characters and may well find a position therein. EUJOPPA DIDYMATA, Sp. 11OV. (J only. A dull, pale flavous species with only the mandibular apices, ocellar region quadrately, antennae except underside of scape, niesouotum except two discal vittae, a lateral f renal mark, the external and dentiparal areae both before and beyond the costulae, and whole of the hind tibiae and tarsi, black ; stigma fulvous. Face coarsely punctate, centrally elevated and not discreted from the laterally elevated and centrally foveate clypeus ; frons and vertex glabrous, with a slight central tubercle above the scrobes. Antennae gradually attenuate throughout, serrate and slightly shorter than the body. Thorax sparsely and not finely punctate, shining ; areola hexagonal, strong and distinctly longer than broad ; basal sulcus and costulae strong ; dentiparal areae traus-strigose and apophyses wanting. Scutellum strongly convex, glittering and sparsely punctate, with somewhat broad lateral carina almost to its apex. Abdomen parallel- sided and im- maculate, with the three basal segments aciculate ; postpetiole abruptly explanate and laterally subelevated, with no discal carinae; gastrocoeli large and deeply impressed, as broad as the intervening space ; valvulae exserted and not large. Legs normal and not elongate, immaculate with the anterior tarsi subinfuscate and both the hind tibiae and tarsi, as well as their strong calcaria, dead black. Wings f ulvescent hyaline 358 Annals of the South African Museum. and not inf umate ; upper basal iiervure postfurcal ; areolet pentagonal and not large, emitting the angled and bifenestrate recm-rent nervure from but slightly beyond its centre ; nervellus postfurcal and straight, intercepted at its lower third. Length, 12 mm. The type was captured at Bulwar in Natal by W. Hay garth. ISCHNOJOPPA, Kriechb. Ent. Naclir. 1898, p. 32. ISCHNOJOPPA LUTEATOR, Fab. Ent, Syst. Suppl. 1798, p. 222. In the same monograph, I have referred to this species' occurrence in Asia, Africa, Australia, and its erroneous record from Europe. It is known throughout Central Africa; but none were hitherto captured so far south as the following typical example. One $ at Mfougosi, in Zulu Laud, by W. E. Jone*. ISCHNOJOPPA EXTREMITAS, sp. nov. $ only. A slender, clear testaceous species with the head except mandibles and palpi and clypeal margin, antennae except underside of scape, and the anus from base of the fifth segment, dead black ; flagellum discally white-banded beyond its centre ; and the wings fulvescent with stigma luteous. In structure it differs hardly at all from /. luteator : the face is shorter, the hind coxae are distinctly more sparsely punctate below, the eyes a little less prominent ; and the wings are narrower, with the discoidal cell a little longer and narrower, and the radial distinctly narrower with the apical radial abscissa straighter. It is, however, abundantly distinct in its im- maculate legs, black head and pale-banded antennae. Length, 12 mm. No nearer locality than South Africa is assigned the type. XANTHOJOPPA, Cam. Ann. Mag. Nat. Hist, vii, 1901, p. 378. Essential Characters. Metanotal areolar carinae entirely wanting ; wings not hyaline; species testaceous. Apophyses distinct; scutellum not strongly convex ; areolet pentagonal and of normal size. Flagellum of $ more or less strongly dilated and of $ serrate. Segments but little discreted, neither angularly produced nor aciculate. XANTHOJOPPA INERMIS, sp. uov. $ only. A dull and testaceous species with the head except discally, thorax except mesonotum, and the scutellum, flavidous. Flagellum On some South African Ichneumonidae. 359 except its six pure white central joints, extreme mandibular apices, ocellar region circularly, terebra and hind onychii, black. Kemainder of hind tarsal joints and apices of their tibiae infuscate. Wings fulvesceut hyaline, with nervures black and stigma luteous. Petiolar area not transversely reticulate. Length, 10 mm. From the six described species of this genus, of which all are from India, the present differs in its obsolete apophyses, subfiliform antennae which are slightly explauate beyond their centre and apically attenuate, in its superficial gastrocoeli which are not elongate, its mainly testaceous hind legs and pale stigma. It most closely approaches X. latebalteata, Cam. Ann. Nat. Hist, xx, 1907, p. 186, which has broad black thoracic and abdo- minal markings, with transversely reticulate petiolar area. The type was captured at East London during July, 1914, by E. M. Lightfoot. TRIBE LISTRODROMIDES. NEOTYPUS, F6rst. Ver. pr. Elieinl. 1868, p. 194. NEOTYPUS CONFLATUS, sp. nov. ? only. A squat, convex, dull brick-red species with small white markings. Head as broad as thorax and posteriorly as broad as the eyes; occiput shining and subglabrous; frons finely punctate, its white orbits elevated and higher than eyes, with scrobes large and glittering; face convex, closely and evenly punctate, continuous with the stout clypeus ; cheeks elongate and buccate, labrum exserted ; mandibles very stout with their subequal teeth black and their base, with an external orbital dot, white. Antennae stout, short and immaculate, not extending beyond thorax. Thorax very stout and as long as abdomen, deeply and not very closely punctate, white-pilose ; iiotauli wanting ; auteradical callosity and subradical line white, niesosternum basally black; petiolar area deeply impressed and occupying three- fourths of metanotum ; areola small and twice as broad as long, cost ulae entire, external area narrower than the dentiparal; spiracles oval, apophyses wanting. Scutellum sparsely punctate, shining and margined throughout ; postscutellum white. Abdomen broadly ovate with the black fourth and broadly white-margined following segments small ; basal segment sparsely punctate, its glabrous apex white and petiole elongate ; second and the nigrescent third segments broader than long, deeply punctate, the former with strong basal gastrocoeli 360 Annals of the South African Museum. and white apical angles ; terebra exserted, black and apically pale ; hypopygium large and apically acuminate. Legs short and somewhat stout; calcaria, all the coxae except base of hind ones, apices of anterior femora and inner side of their tibiae, pure white; tarsal claws strongly pectinate. Wings small and broad, hyaline with stigma and nervures black ; lower basal uervure antefurcal, areolet subquadrate. Length, 8 mm. A very typical species of this distinct genus. Captured at Chinde in Mozambique, Portuguese East Africa, by K. H. Barnard, during November, 1912. ANISOBAS, Wesm. Nouv. Mem. Ac, Brux. 1844, p. 111. AlS T ISOBAS RABULA, Sp. UOV. ? only. A somewhat bright red species with the black antennae, abdomen and legs all white-marked. Head posteriorly, mandibles at both extremities and apex of clypeus black ; orbits not white-marked. Scape red-dotted beneath, and a central flagellar baud white. Thorax with small anteraclical white callosity, and the whole sternum black ; postscutellum red. Abdomen black with apical angles of two basal segments, and the anus, white-marked ; postpetiole glabrous with only a row of punctures before its apex ; hypopygium covering terebral base but not apically produced. Legs black with only apices of front femora and the inner side of the anterior tibiae, with all calcaria, white; claws not pectinate. Wings slightly but distinctly infumate. Length, 7 mm. The position of the Listrodromides, and their very right to Tribal rank, are yet uncertain: this species, compared with the last, goes some way to uphold Prof. Thomson's view (Opusc, Ent. xix, p. 2099) that the genera Ijistrodromus and Neotypus which have pectinate tarsal claws, and Anisobas which has not, form a small and compact group among the Amblypygini, sharing the following characters in common: Clypeus not discreted, its lateral foveae obsolete ; genal costa continuous ; antennae inserted high on frons, with scapes not further from each other than from the eyes ; metauotal costulae entire, the dentiparal area externally arcuate ; tibiae submutic, the hind ones hardly longer than, their femora ; lower basal uervure oblique, autefurcal and pretty well straight. The above two species possess all these characters and, indeed, differ inter se only in the features indicated under the latter. The type was captured at Stellenbosch, Cape Colony, by R. M. Lightfoot, during September, 1913. 0>i some South African Ichneumonidae. 361 TRIBE ICHNEUMOXIDES. SUBTRIBE OXYPYGINI. BYSTRA, Cain. Aiiu. Nat. Hist, ix, 1902, p. 149. Generic Characters. Head with the occiput obtusely margined, the cheeks strongly buccate, the labruni exserted and upper mandibular tooth the longer. Antennae stout and, beyond their centi-e, strongly compresso-dilated ; basal flagellar joints but little longer than broad. Metathorax with complete areae and linear spiracles, its apex sub- vertically declivous; areola subcrescentic or hexagonal, basally not curved. Scutellum deplanate, laterally and apically cariuate. Abdomen with only seven visible discal segments ; ventral segments two to four, and base of the fifth, plicate ; terebra not strongly exserted. Tibiae and tarsi spinulose. Areolet pentagonal ; basal uervure continuous through median ; nervelet more or less distinct. I here give a revised account of this genus since, upon examining the genotype, from India, I found several of Cameron's characters quite erroneous and these are rectified above. The genus is excluded from the Joppides only by its lack of basal metanotal sulcus. One species alone has hitherto been known. BYSTRA QUADRATA, sp. uov. $ only. A rufesceut-testaceous species, finely punctate and some- what dull with the anus glittering ; pleurae, sternum and coxae subflavescent. Pace, clypeus, cheeks, all the orbits broadly, and the eighth to sixteenth flagellar joints, white; costa, mandibular apices and remainder of flagellum, alone black. Face deeply and not very closely punctate ; lateral clypeal foveae large ; whole disc of thorax very closely and finely punctate, with notauli obsolete and the petiolar area both discreted and shagreened ; metanotal areae entire and strong, with areola hexagonal, basally truncate and hardly longer than broad. Abdomen a little narrower than thorax ; petiole slender, not short, and half breadth of postpetiole, which is convex and finely shagreened with no cariuae nor punctures ; gastrocoeli small and lateral ; second and third segments evenly and very finely punctate, dull with apex of the latter and whole of remaining segments glabrous and uitidulous ; hypopygiurn not extending to base of the black and hardly exserted terebra. Legs normal and not slender; hind coxae obsoletely punctate and not scopuliferous, their tibiae a little curved. Areolet pentagonal, 362 Annals of the South African Museum. laterally not quite coalescent above, emitting recurrent nervure from its centre. Length, 14 mm. The type and co-type were taken at Salisbury, in Southern Rhodesia, during 1915 by D. Dodds, and at Salisbury in September, 1913. EUPALAMUS, Wesm. Nouv. Mem. Ac. Brux. 1844, p. 13. This originally ill-differentiated genus is well characterised by Prof. Thomson (Ann. Soc. France, 1886, p. 11) : Cheeks always quite short and in ? sub-buccate, mandibles stout and clypeus apically truncate with labrum distinctly exserted ; face short and the confluent antennal scrobes large and glittering ; vertex not broad. Flagellum of ? centrally dilated, in its seventh to fifteenth joints with elevated carinae. Ai'eola longer than broad, and coxal area distinct ; scutellum not transverse. Petiole gently and equally curved throughout ; post- petiole not aciculate, somewhat smooth or rugulose, with its central area twice as broad as the lateral ones ; gastrocoeli small and sub- rugulose, thyridii far from base and not large. Posterior tibiae and femora stout. Thorax and abdomen somewhat deplanate. EUPALAMUS CONVEXIUS, sp. nov. ? only. A stout and dull black species with the palpi, a central flagellar band, and inner side of the front tibiae, white ; face, cheeks, frontal orbits, underside of scape, a broad auteradical line, small callosities below radices, a discal mesonotal mark and whole of both the scutellum and postscutellum, sanguineous-red (perhaps stramineous in nature) ; front tarsi iufuscate. Head posteriorly not broad ; face closely and coarsely, frons closely and evenly, punctate ; antennae abruptly attenuate at extreme apices, with the peiiultima.te joint and that preceding it (perhaps accidentally) deeply excavate. Thorax with nonotauli; metanotal costulae strong; areola elongate, subglabrous, nitidulous and but indefinitely separated from the strongly punctate, pilose and strongly discreted petiolar area. Scutellum large, strongly convex, glittering and very conspicuous. Abdomen fusiform and immaculate with the petiole narrow and postpetiole abruptly explanate, finely rugulose, with prominent spiracles. Legs normal and coxae simple ; wings broad and a little clouded ; costa, stigma and nervures black ; lower basal nervure but slightly postf urcal ; areolet pentagonal, not coalesceut above, emitting recurrent subceiitrally. Length, 13 mm. The type occurred at Bulwer in Natal during 1914 to W. Hay- garth. On some South African Iclmeumonidae. MELANICHNEUMON, Thorns. Opusc. But. xviii, 1893, p. 1954.

Legs normal and not slender. Wings broad with the costa and nervures inf uscate, stigma castaneous ; areolet pentagonal. Length 12 mm. Allied to M. saturatorius, Linn., but stouter with the flagellum much more iucrassate, in colouration it resembles Neotypus lapidator, Fab. Type and co-type were taken at Potchefstroom in the Transvaal by T. Ay res. MELANICHNEUMON B.UFATOR, sp. nov. onlv. Brick-red, even to the mandibles and terebra, with only the posterior coxae infuscate ; the orbits indefinitely and a central flagellar band paler and sometimes whitish.

Head and the pilose mesouotum dark red ; face and clypeus uneven and coarsely punctate, dull flavidous with the latter laterally black and apically truncate ; f rons and vertex closely and deeply punctate. Antennae flavous, stout and strongly attenuate throughout, hardly extending beyond basal segment, with the scape discally black and the half- 366 Annals of the South African Museum. dozen apical joints excavate beneath ; protliorax, meso-pleurae and -sternum, and metatliorax except a discal mark, black; notauli and metauotal basal sulcus wanting ; all carinae obsolete, costulae wanting, areola subtransverse and only basally carinate. Scutellum and post- scutellum glabrous, glittering and slightly convex. Abdomen dull, closely punctate, castaueous, and elongate-ovate with only base of the fourth and fifth segments indefinitely black ; postpetiole broad, finely aciculate-punctate and strongly bicarinate; gastrocoeli deeply impressed and fully as broad as the aciculate intervening space; anus obtuse and smoother. Legs fulvidons with coxae and trochanters partly nigrescent; hind claws small. Wings hyaline with the stigma and nervures deep brunneous ; areolet broad above. Length, 11 mm. The short and setigerous flagellum combined with indefinitely dark red and apically obtuse body lend this species much more the appear- ance of the Indian Protictmeumon (Amllyjoppa) rnficeps, Cam., than any species of the present genus with which I am acquainted. The type was captured at Utrecht in Natal during 1907. AMBLYTELES, Wesm. Nouv. Mem. 1844, p. 111. Thorns. Opusc. Ent. 1894, p. 2090. AMBLYTELES AUXIFER, Tosq. Mem. Soc. Ent. Belg. 1896, p. 82, ? . ? only. A stout black species with dull red head, mesonotum, petiole and legs. Head red and not constricted behind eyes, closely punctate with the clypeus more sparsely and as long as the elevated epistoma, its sides and the maudibular apices black. Antennae stout and filiform with their apices strongly attenuate, nigrescent with scape red and (in these examples) no pale central flagellar band. Thorax dull and discally deplanate, very finely punctate with no notauli ; metanotum coriaceous with longitudinal carinae entire though weak ; areola not smoother, subquadrate with sides a little curved ; petiolar area scabrous with basal carina strong and apophyses distinct though small. Scutellum black, subglabrous and glittering, hardly convex. Abdomen elongate-ovate and black with only the basal segment entirely, and disc of the 7th, somewhat clear red ; postpetiole broad and deplauate with only a few distinct discal punctures, carinae obsolete; gastrocoeli small and much narrower than the simple intervening space ; second and third ventral segments plicate ; n JPPJg ium extending to the nitidulous anus, terebra red. Leo-g O On some South African Ichneumonidae. 367 stout arid dark red with all the trochanters, and the simple coxae, black ; hind femora inf uscate. Wings distinctly and evenly nigrescent throughout ; stigma and nervures black ; basal nervure continuous through median, areolet broad above. Length, 12 mm. Very like the last species but differing, besides the divergence of the gastrocoeli, in the postpetiolar and metanotal struct ui'e, abdominal colouration and deeply infumate wings. I have no doubt it is the insect described under this name by Tosquiuet, but give an account of it, since it appears to belong to his " var. 1," which is barely mentioned. "Le Cap de Bonne- Esperauce " (Tosq.). Port Elizabeth by J. L. Drege, and Johannesburg in 1898 by A. Ross. AMBLYTELES TUBERCTJLATA, sp. nov. ? only. A dull, brick-red species with profuse black markings, and evenly infumate wings having the stigma stramineous. Head closely and coriaceously punctate, with the truncate and margined apex of the narrow clypeus alone smooth ; mandibular teeth, of which the lower is very small, the superficial clypeal foveae, vertex and occiput, alone black ; apex of scrobes with a minute and acute central tubercle. Antennae not short, fulvous and somewhat slender to beyond their centre, thence black and compresso-dilated, with their apices strongly attenuate. Thorax stout and coriaceously punctate with the pro- sternum apically, mesopleurae except above, meso- and meta-sternum, metapleurae, frenuui, metauotal base linearly, mesonotum except two vittae, and the scutellar fovea, black ; metauotum with elongate but obsolete areola and weak lateral carinae indicated, its spiracles large and remarkably strongly elevated ; apophyses wanting. Scutellum convex, dull and. coarsely punctate, with strong lateral carinae to beyond its centre. Abdomen exactly fusiform with the terebra, and basal half of the second to fourth segments both discally and ventrally, dead black ; postpetiole deplanate and so finely aciculate as to appear shagreened, with prominent spiracles and apical angles ; second segment basally glabrous, succeeded by very rough puncturatiou, its gastrocoeli somewhat deep but not large ; second to fourth ventral segments very definitely plicate ; hypopygium not acuminate, extending nearly to the anus. Legs elongate and somewhat slender, with only base of the simple and closely punctate hind coxae black. Wings distinctly infumate though not nigrescent, with nervures piceous ; costa and stigma bright stramineous ; nervelet strong, basal nervure subcon- tinuous, areolet broad emitting recurrent from slightly before its centre. Length, 12 mm. The structure of the metanotum and espe- cially of its spiracles, the convex and margined scutellum, and the rare 368 Annals of the South African Museum. contrast of the dark wings with very pale stigma, render this insect, which has much the facies of a pale A. armatorius, Forst., remarkable. Found at Saldanha Bay, eighty miles from Cape Town, during Sep- tember, 1912, by L. Pcringuey. SUBTRIBE PLATYUEINI. EUKYLABUS, Wesrn. Nouv. Mem. Ac. Brux. 1844, p. 150. EURYLABUS CYANOCROCEUS, Sp. 11OV. ? only. A large and slender, dull and dark metallic blue species with the basal two-thirds of the strongly attenuate flagellum (becoming stramineous centrally), the large and strongly convex, sparsely punc- tate and inimarginate scutellmn, with the whole legs except coxae and trochanters, bright croceous. Metanotum deplanate and scabriculous, with basal petiolar carina strong and all others wanting ; postpetiole deplanate, narrow and subglabrous ; abdomen not broader than thorax, with its terebra subconcealed ; hind coxae elongate and simple. Wings hyaline with the stigma and nervures black ; basal nervure continuous, nervelet elongate, areolet a little higher than broad, emitting recurrent from its centre. Length, 15 mm. A most conspicuous species in its brilliant colouration. The type is from Gfiftsberg, Ehyusdorp, in Cape Colony, during September, 1911. PLATYLABUS, Wesm. Nouv. Mem. Ac. Brux. 1844, p. 150. PLATYLABUS RUFESCENS, sp. uov. A dull, dark brick-red species with the sternum, hind coxae, their trochauters and femora, the fourth to seventh and apical flagellar joints, and the stigma, black ; the eighth to fifteenth flagellar joints, and anus from apical half to the fifth segment, white. Head narrow and constricted behind the eyes ; f rons and face strongly and evenly punctate ; clypeus not basally discreted, with its apex slightly rounded and black-margined ; cheeks elongate and not buccate. Flagellum slender and filiform to near its apex, before which it is slightly com- presso-dilated. Thorax very closely and evenly punctate, dull, with no notauli ; metauotum deplanate with areae entire, costulae weak, areola oval and longer than broad, spiracles linear and not small; petiolar area abruptly declivous, discreted, with its basal carina strong On some South African Ichneumonidae. 369 and apophyses obtuse. Scutellum closely punctate, not convex, margined to its apical third. Abdomen deplanate, oval and dull, with the basal segment nitidulous, sparsely punctate and excarinate ; thyridii, transverse and superficial, small. Legs slender and elongate. Wings hyaline with basal nervure continuous and areolet not coales- cent above. ?. . . . The J differs slightly in having the flagelluni setigerous and internally serrate towards its apex, with only four central joints disc-ally white ; and the areola a little transverse, with strong costulae. The legs are darker, the abdomen nigrescent from base of second to centre of fifth segments, with extreme apex of the fourth also white, as are the palpi, anterior coxae beneath, extreme clypeal apex and part of the facial orbits. Length, 5 <$ , 9-10 mm. It is allied to P. rufus, Wesm., but with the legs more elongate and slender, etc. L. C. Peringuey took the typical female at Green Point, Cape Town, and T. Ayres found the two co-typical males at Potchefstroom in the Transvaal. PLATYLABUS PULCHELLUS, sp. nov. $ only. Extremely like the last species and similarly, though more profusely, white-marked : thus it has in addition the vertical orbits and sides of the clypeus both broadly, all the trochanters, the post- scutellum, whole apex of second and apex of third segments laterally white, with the fourth and fifth alone entirely black. The hind tibiae and tarsi, and base of flagelluni, are entirely black. Structurally it is known by the absence of metanotal costulae and the elongate areola, which is subparallel- sided and nearly twice as long as broad, broadest before its centre ; by the glabrous postpetiole and subcircular thyridii. Length, 10 mm. Captured at Mfongosi in Zululand by W. E. Jones during December, 1914. PLATYLABUS MINIATULUS, sp. nov. u.>itir
