 Wings clear, veins brownish yellow. 



Frons distinctly, but not greatly, over one- third as wide as head; 

 triangle large, occupying almost the entire vertex, and extending 

 nearly to anterior margin; lateral frontal hairs strong, four along eye 

 margin being bristlelike, the whole four directed backward, the lower 

 two slightly outward; antennae large, thii'd joint rounded; arista not

 very numerous, and irregularly arranged; scuteUum flattened on disk, 

 subtriangular, apex truncate, apical bristles placed on angles, long, 

 cruciate, the subapical pair separated from apical by as far as distance 

 between apical bristles. Legs strong, hind femora thickened some- 

 what; surfaces of all legs covered with hairs; apical spur of hind tibiae 

 very long, strong, and curved, in length reaching nearly to apex of 

 metatarsus, its base at near apex of tibia. Wings with third costal

Originally described from Cuba. There is a large series of speci- 

 mens of both sexes in U. S. National Museum collections from Andros 

 Key, Bahama Islands, West Indies, ''on shells," June, 1912 (P. 

 Bartsch); and one male from Havana, Cuba (E. A. Schwarz). 



The male has the head a little smaller than the female, and has two 

 very long hairs attached to the proboscis as shown in figure 21. 

 In other respects they are similar. 



PSEUDOHIPPELATES, new genus. 



This genus differs from Hippelates in its much more elongated 

 shape, the possession of frontal bristles, and the stronger bristling of 

 the cheeks and anterior mouth margin. The hypopygium of the male, 

 is large and knoblike. 



Type of this genus. — Hippelates capax Coquillett.

Male and female. — Shiny black; disk of mesonotum distinctly 

 obscured by yellowish gray pollmosity; frons black, anterior margin 

 yellow, carried in the form of a short stripe backward to the apex 

 of the triangle and separating the velvety black side spots which
