Head a little longer than broad; cheeks slightly arched, without

 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-

Antennae eight-segmented, not as long as the width of the meso-

 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.

Win?s well developed, membrane reaching nearly or quite to the

 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.
