In the colour of the wings this resemhles the beautiful 

 H. sericeipennis, Bingh., but is quite distinct in the form of 

 the clypeus, pronotum and joints of the flagellum, as well 

 as in size and colour. From H. barbara, Lep., it differs in 

 the form of the clypeus, in the more slender flagellum, 

 in the much more extensive fuscous area of the wings, 

 and in details of neuration. 



Hemipepsis mlanjensis, sp. n. 



$ . Nigra ; capite, antennis, pronoto, mesonoto, scutello, post- 

 scutello, segmento abdominali sexto, pedibusque, coxis exceptis 

 fulvis ; alis flavis, apice anguste fuscis. 

 Long. 18 mm. 



? . Clypeus very shallowly emarginate anteriorly. An- 

 tennae stout, the second joint of the flagellum longer than 

 the third by about one-quarter. Eyes slightly divergent 

 towards the clypeus, separated on the vertex by a distance 

 equal to the length of the second joint of the flagellum, 

 posterior ocelli a little nearer to the eyes than to each other. 

 Pronotum very widely arched posteriorly; postscutellum 

 feebly convex. Median segment without lateral tubercles, 

 rounded posteriorly, not truncate, regularly transversely 

 striated. Transverse groove of the second sternite situated 

 just before the middle; sixth tergite closely microscopically 

 punctured, with sparse setigerous punctures intermingled. 

 Comb of fore tarsi short, the metatarsus with seven spines ; 

 serration of the hind tibiae only feebled developed. First 

 recurrent nervure received just before the apex of the second 

 cubital cell, second just beyond one-third from the base of 

 the third cubital cell; third abscissa of the radius as long 

 as the first and second combined. Discoidal spot distinct. 

 Cubitus of hind wing received just before the transverse 

 median neavure, almost interstitial.

The tarsal ungues are not normal, being bifid at the apex, 

 the inner division truncate ; on the middle of the ungues 

 there is a small tooth as in Crpptochilus, but no basal tooth 

 as in Hemipepsis. The only species described in which the 

 ungues are at all similar is Hemipepsis unguicularis, Kohl 

 (1013), but in that species the wings are blue-black; the 

 inner division of the bifid ungues pointed and the median 

 both oblique and strongly developed so that the ungues 

 appear to be trifid. The fuscous margin of the wings in the
