darkened above, the wings have the cross-veins infuscated, 

 the arista is plumose, the thorax has three pairs of 

 strong postsutnral dorso-ccntrals and no presutural acro- 

 stichals. The niid-til)ia lias an antero-dorsal median bristle, 

 the hind tibia one antero-ventral and two antero-dorsal 



bristles. 



Locality, top of the Aberdare Mts., Kenya Colony 



[T. J. Anderson). Originally described from East Africa in 



i9U. 



Subfamily Coenosiinm. 

 Genus Pygophora, Schiner. 



I present herein a key to the species of this genus known 

 to me. It is not possible from a study of the material 

 available to me to make a complete key to the females. 



I recapitulate the generic characters cited in Part I. of 

 this series of papers : — Arista remarkably long-haired to 

 middle ; frons much wider at anterior margin than at vertex, 

 each orbit with four bristles, one in line with the anterior 

 ocellus and three strong bristles anterior to it, the upper 

 two very close together ; mid-tibia with no anterior bristle ; 

 hind tibia with one antero-ventral and two postero-dorsal 

 and antero-dorsal bristles.
