rowly brownish. The greater part of the outer half of 
the marginal cell and all of the stigmal portion of the 
costal cell, except the apex, and all of the costal cell, are 
hyaline as is the remainder of the wing. There is some 
suggestion of two tones in the colored portion of the wing 
as the posterior margin of the second longitudinal vein 
seems to be slightly more yellowish and the area behind 
more blackish. Abdomen: dull black with prominent 
bands of pale creamy yellow tomentum as follows: the 
posterior margin of the first segment except the sides, 
the entire anterior margin of the third segment and 
fourth segment. The pile of the second segment is en- 
tirely dense, short, black setate except that the lateral 
margins are narrowly fringed with conspicuous, pale, 
brassy yellow pile. The third segment is entirely brassy 
yellow pilose although in some lights it appears to be 
blackish. The margin of this segment is likewise tinged 
with yellow pile. Fourth segment with longer and there- 
fore more conspicuous brassy pile, subappressed through- 
out the segment except for the basal tomentum. Hypo- 
pygium thickly pale yellow pollinose with long, scattered, 
golden pile.

The pile of the face is pale yellow and that of the front 
of the same color with four or five black hairs intermixed. 
The vertex is black with black pile except in front of the
