yellowish-gray pruinose, anterior margins of the segments and a trace of a 

 median line, darker gray; six or eight pairs of depressed marginal setae on each

 extensor, two or three on the posterior flexor, and one or two on the posterior 

 median surface; hind tibia with two long bristles on the median extensor 

 surface, three or four on the outer extensor, three small ones on the outer 

 flexor, and three or four small ones on the inner flexor surface. Fore and hind 

 femora each with a sparsely placed longitudinal row of long setae on the flexor 

 surface and a row of shorter ones, of increasing length distally, on the outer 

 extensor surface. Wing yellowish, more grayish toward the apex; costal 

 spine shorter than the r-m crossvein; Ri ends shghtly distad of this crossvein; 

 the m-cu cro.ssvein distmctly flexed; R4+5 and M1+2 slightly divergent.

This species closely resembles H. alcathoe but differs in the 

 chaetotaxy of the legs, in the structure of the hypopygium, and in 

 having the abdominal markings less distinct.

Hylemjria (Crinura) trichodactyla Rondani {=Chorlophila trichodactyla, 

 = Phorhin platura Meigen in part) 



The collection contains specimens of this species from various 

 localities in New York, as well as from Sandford, Ontario and 

 Truro, Nova Scotia. This species has doubtless frequently 

 been confused in American collections ^ith Phorhia fusciceps 

 ( = P. cilicrura Rondani) and is probably the P. platura Meigen 

 referred to in Aldrich's Catalogue. P. platura of Rondani^ 

 is a different species. H. trichodactyla resembles fusciceps in 

 having the flexor surface of the hind tibia ciliated, but differs 

 in having long bristly hairs on the extensor surface of the first 

 segment of the middle tarsus. 



Fanninae 



This subfamily is represented in the State of New York by the
