Tin.; single specimen representing this species is a male, as the number 

 M| abdominal segments show: lint tlie winjrs are lacking. The in>ect i- 

 viewed from above. Tlie liead and thorax are slightly darker than the 

 abdomen, but otherwise the whole liodv is uniformly fuscous, somewhat 

 darker than the stone. The head is very small, subqiiadrate, slightly 

 broader behind, and the posterior angles nearly rectangular ; the anterior 

 margin of tin head is broadly and pretty regularly rounded, and the whole 

 head is nl' about equal length and breadth. The thorax is very regularly 

 ovati-. broadest next the insertion of' the front wings (traces of the origin of 

 which can be seen), nearly twice as long as broad, rapidly tapering on the 

 metathorav The peduncle, as seen from above, is square, half as broad as 

 the head, the hinder edge showing by its thickening that it was probabh 

 elevated at this point. The abdomen is plump, rounded ovate, scarcely !<-- 

 rounded posteriori v than in front, only one quarter longer than broad, 

 broader than the thorax, composed of six segments, of which the first, third, 

 and fourth are about equal in length, and the second half a- I in.
