9 dull lilack. opaque; legs and antennse basally luteous, the latter fus- 

 cous apically ; mandil)les fuscous except at the base: abdomen somewhat 

 piceous. 



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

 late surface sculpture, a little coarser on the head ; finely, shallowly and 

 somewhat remotely and sparsely punctate ; hairy clothing inconspicuous. 

 Head a little longer than wide, width between the eyes a little more than the 

 length from eye to vertex, length in front of the eyes not great ; flatly con- 

 vex above, depressed in front, a little tumid l)eneath. the greatest depth 

 beneath the eye ; vertical margin straight, temples rounded, eyes flatly con- 

 vex ; antennse a little longer than the head, pedicel and first funicle segment 

 a little longer than wide, the following segments as wide as long, antenna'l 

 fossas deep; clypeus carinate, apically depressed and projecting slightly in 

 front of the anterior margin of the head, sloping at the sides, the carina 

 extending backward shortly on the top of the head ; mandibles fairly slen- 

 der, curved, truncate apically and toothed, liase not quite reaching the eye. 

 lower angle protuberant ; gula convex, medially foreshortened, wider than 

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