and pilose, the yellow pile expanding gradually immedi-

brassy yellow pile and an indistinct, nearly bare sublateral 
stripe in addition to the shining medial stripe over the 
face. The front is shining black with a distinct tuber- 
cular swelling at the upper part of the front and a very 
slight, rounded elevation subapically below over which 
there is a medial crease. The frontal pile is quite long 
and sparse and chiefly black with a few yellow hairs along 
the sides and a thin line of yellow pubescence along the 
eye margins. The front and the upper part of the face 
are but slightly projecting and the facial concavity very 
low. The occiput is black with black pile in front and 
black and yellow pile behind; the yellow pile is more

is an anterior fringe of black hairs which is quite long

in front of the ocelli is yellow pubescent. The antennae 
are comparatively short ; the third segment is at least one 
and a half times as long as wide when viewed laterally, 
perhaps a little longer; its basal margin is reddish and 
the remainder black ; the arista is light brownish red with 
fine apex ; the first two segments are black with black pile.
