 nally striate. Length, 8 mm. 



Head black, sparsely clothed with erect and recumbent, long, black 

 hairs; mandibles acute at the apex, no evident tooth within; scape 

 shining, sparsely j^unctate, sparsely clothed with coarse, black hairs; 

 first segment of flagellum long, twice as long as it is broad at the

 tered, microscopic punctures, posterior half with large, confluent 

 punctures; metapleura shining, impunctate, except for a few large, 

 shallow punctures ventrally; sides of propodeum rounded into pos- 

 terior face, shining, impunctate on the anterior half, with large shal- 

 low reticulations on the posterior half; posterior face of propodeum 

 deeply and coarsely reticulate ; scutellar scale absent.

 coarsely sculptured on the posterior third ; second tergite with large, 

 elongate, confluent punctures, clothed with long, orange hairs, except

Closely related to stevensi and may prove to be only a variety of 

 that species. The paratypes vary from 6 to 11 mm. in length.
