 Phorautha humeral is, n. sp.

 the wings more whitish, the base and costal margin as far as first vein 

 more or less brown. Length, 4-5 mm.

 Epigrimyia Illinoensis, n. sp.

 wider ; antenna? and proboscis longer ; front tibia? reddish ; claws and 

 pulvilli longer. Length, 5 mm.

Winthemia Illinoensis, n. sp. 



This species closely resembles IV. quadripustulata. It differs in its 

 smaller size, the bristles on the abdomen, especially in the male, more 

 sparse, more erect, longer ; the second segment in male with a marginal 

 pair of macrocha?tae ; hind tibiae, outwardly, in both sexes, less regularly 

 ciliate and presenting a long bristle near the middle. Length, 6-9 mm. 



Carlinville, Illinois ; five o , three ^ specimens. The sexes were 

 taken in copula. 



The name may not stand : the presence of this species seems to 

 throw some doubt on Coquillett's synonymy of W. quadripustulata.
