Long, -ig-o, lat. If-lf mm. 



Head shortly conical, impiinctate ; forehead with a central

 long as head, stout, parallel-sided, sliglitly curved, punctate 

 on the sides, but glabrous dorsally ; antennie stout, ferru- 

 ginous. Prothornx about as long as broad, apex truncate, 

 much narrower than base, wiiicli is bisinuate, sides subparallel 

 from base to beyond middle, narrowed anteriorly, and with a 

 faint constriction at apex ; upper surface slightly convex, 

 with deep subremote punctuation and a median basal impres- 

 sion ; the central carina scarcely noticeable, except in the 

 basal impression; colour black, bare, shining. Elytra i\\\i\\Q 

 broader than ])rotl)orax at the shoulders, which are roundedly

Long. 4-4^, lat. 1^ mm. 



y/ea^/ conical, vertex impunctate; forehead puuctulate and 

 with a central fovea ; eyes subdepressed. Rjntrani longer 

 than head, curved, subcylindrical, and not dilated at apex ;

 rounded, slightly constricted behind apex, broadest about 

 middle ; upper surface somewhat convex, closely and very 

 coarsely punctured throughout, and with a deep triangular 

 central impression, broadening from apex to base, the im- 

 pression itself rugosely punctured and containing a complete 

 smooth carina. Elytra separately rounded at base, a little 

 broader than prothorax at shoulders, wdiich are obtusely 

 prominent, sides parallel to beyond middle ; upper surfi\ce
