pairs of orbital bristles in the female, none in the male, frontal bristles 
descending to base of third antennal joint, sides of face at narrowest 
point each one-third as wide as the median depression, thickly covered 
with black bristles, cheeks in the male slightly narrower, in the female 
broader, than the eye height, vibrisse widely separated, inserted on a 
line with the front edge of the oral margin, facial ridges bristly on the

fourth of face in the female, third joint in the male six, in the female 
three, times as Jong as the second, arista thickened on the basal half, 
the penultimate joint slightly longer than broad; palpi clavate, short, 
less than half as long as the proboscis beyond the basal articulation, 
the latter slightly over one-half as long as height of head, eyes bare,
