Head a little longer than broad; cheeks slightly arched, without 
warts, posterior portion of dorsal surface quite noticeably transversely 
striated. Ocelli large and well separated, posterior pair placed about 
opposite the middle of the eyes whose margins they nearly touch, dark 
brown; postocular bristles well developed, sharp-pointed. Mouth cone 
shorter than its breadth at the base and very rounded at the tip, reach- 
ing to about three-fourths the length of the prothorax. 
Antennae eight-segmented, not as long as the width of the meso- 
thorax, segments short and stout, the fourth a little thicker and con- 
siderably longer than the others, sense cones short. 
Prothorax considerably wider than long when measured to outer 
angles of the coxae, somewhat triangular in outline, sides converging 
anteriorly, a spine on each posterior angle. 
Mesothorax somewhat wider than prothorax, sides nearly parallel 
but somewhat narrowed in the middle. 
Legs short, fore femora but slightly thickened. 
Wings well developed, membrane reaching nearly or quite to the 
end of the tube in most individuals; decidedly constricted in the mid- 
dle; hairs of the fringe long and nearly equal, in a single row except 
on the hind border of the fore wing where there are eight hairs of a 
second row. 
Abdomen about as wide as mesothorax, usually widest at the base 
from which it slopes to the tip, gradually at first and then more ab- 
ruptly. Tube rather small and short, tapering but little, six terminal 
spines longer than the tube, and a number of shorter ones. Spines on 
the remainder of the abdomen weak and inconspicuous.
