Head, length .48 mm., width .23 mm.; elongate, con- 

 ical, with clypeus expanded, and obtusely angled in front 

 and at sides ; the expanded part of the clypeus is un- 

 colored ; one lateral hair on expanded clypeal portion, 

 two in front of the suture (one rising from dorsal surface 

 and one from ventral), one at the suture, and two rising 

 from the ventral surface and projecting beyond the lateral 

 margin behind the suture, and one long hair rising from 

 the internal band and projecting beyond the lateral margin 

 of the forehead; trabecular small but distinct, acute; 

 temporal margins subparallel, with one long hair and one 

 shorter hair; occipital margin concave; eyes inconspicu-

 of mandibles to enclose oral fossa. 



Prothorax truncated, conical, sides converging in front,

 tire segments, and a single hair at posterior angle. Meta- 

 thorax but little longer than prothorax, wider, also trun-
