 shore of Victoria Nyanza (S. A. Xeuve), September; Bu-

This splendid species is one of the few African Crypto- 

 chillis known to me in which the male has the ungues bifid 

 as in Cyphononyx. Species showing this sexual difference 

 are fairly numerous in India and the Malayan region, and 

 one occurs in Madagascar. The tuberculate postscutellum 

 of the male is remarkable in this species. It appears to be 

 common in Uganda, but I have not seen specimens from any 

 other locality. 



Type in B.M. 



The African species with dark wings, which have the tarsal 

 ungues differing sexually as in gowdeyi, are : —

I suspect that anguliferus and severini are identical. 



Pseudagenia pseudocyphononyx, sp. n. 



$ . Nigra, opaca ; flagello, articulis duobus apicalibus infumatis, 

 femoribus, basi extrema nigra, tibiis tarsisque fulvo-ferrugineis ; 

 mandibulis basi palpisque fusco-f'errugineis ; alis nigro-violaceis. 



Long. 20 mm. 



? . Clypeus very broadly rounded at the apex, sparsely 

 clothed with black hairs ; antennae long and slender, slightly 

 exceeding three-quarters of the length of the insect, the first 

 and second joints of the flagellum combined half as long- 

 again as the third joint. Eyes separated on the vertex by a 

 distance equal to the length of the third joint of the flagellum ; 

 posterior ocelli much further from the eyes than from each 

 other. Scutellum and postscutellum evenly convex, the sides
