Key to the Species. 



a. Basal portion of nietanotum with acute spines 

 t on the posterior lateral angles. 



a'. Reticulate, striate; no raised acute little 



granular tubercles on abdomen, a few on 



margins of head and thorax.

b' 2 . Legs entirely black 



b'. Reticulate, striate, in part punctate ; head,

margins of head and thorax. 



2 . First node of pedicel rounded in front . . 



b' 2 . First node of pedicel obliquely truncate 



in front 



b. Basal portion of metanotum without acute

. Dull dead ink-black, with a mere touch of castaneous brown 

 at the apex of the scape and of the flagellum of the antenna, 

 and at the joints of the legs ; pilosity almost altogether absent, 

 merely a few very short white bristly hairs, chiefly at the apex of 

 and beneath the abdomen ; head, thorax and abdomen finely 

 punctured, granulate and opaque, the legs and pedicel coarsely 

 rugose, granulate, the margins, lateral and posterior, of the head 

 and thorax studded irregularly with little blunt points ; the

 running into striae. Head much broader than long, lightly convex, 

 the occiput widely emarginate, the posterior lateral angles pro- 

 minent, slightly dentate ; mandibles subtriangular, obscurely 

 striate ; clypeus large, widely emarginate anteriorly ; antennae 

 stout, when folded completely hidden from above in the deep 

 fossa beneath the eyes. Thorax : the pronotum broader than long, 

 the anterior margin broad ,-ind transverse, the pro-mesonotal suture
