median carina, its spiracle large and nearly round. Abdomen short and stout, no longer than 

 the thorax, .its second segment occupying half of the surface. Scutellum longer than the 

 propodeum. Posterior tibia? apparently with but one apical spur. The male is the same, but 

 abdomen mure depressed and cylindric; antennae entirely different, the scape much shorter, 

 dilated ventrally, pedicel not much longer than thick, the ring-joint like a. ring; first funicle 

 joint very transverse and lamellate, following five joints increasing in length, each bearing a 

 long, curved, cylindrical ramus from its disto-lateral margin, joint - no longer than tin' 

 diameter of its ramus and practically forming a continuation of it, joint .". slightly long! 

 than wide; joint <i much longer than wide; the rami longer proximad, the shortest and 

 distal one distinctly longer than any single joint of antenna. Proximal joint of club elongate 

 obconic, forming halt of the club and longer than the distal funicle joint; the other two club 

 joints sul equal. Funicle and rami with sparse, rather long, fine hairs. Male antenna?
