$ dull shining black, legs and antennae brown. 



Head and thorax to the propodeum with a microscopically fine reticu-

 tellum ; coarsely, shallowly and fairly closely punctate, and hairy. Head a 

 little longer than wide, widest across the eyes, narrowing in front and 

 behind, width between the eyes a little more than the length from eye to 

 vertex ; flatly convex above, depressed in front, a little tumid beneath ; 

 vertical margin straight, temples rounded, eyes convex ; antennae reaching 

 the mesoscutum, all the segments longer than wide, antennal fossae deep ; 

 clypeus reduced by erosion from the sides to a thin, carinate ridge, apically 

 depressed and projecting slightly in front of the anterior margin of the 

 head, declivous at the sides, the carina extending backward on the top of 

 the head beyond the base of the antennae ; mandibles slender, curved, trun- 

 cate apically and toothed, base not quite reaching the eye ; sides of the head 

 flat, gula flatly convex, medially foreshortened, wider than long, narrowing 

 behind, anterior margin arcuately concave, posterior margin incised ; propo-
