Not very stout and only moderately ventricose, polished, im 

 punctate anteriorly, the elytra very coarsely and deeply but some 

 what sparsely punctate, the punctures much feebler toward apex 

 body black, or piceous with the elytra paler brownish ,; prothorax 

 paler at base and apex ; legs and antennae pale rufo-testaceous 

 pubescence cinereous, fine and rather sparse anteriorly, long 

 erect but somewhat sparse on the elytra. Head much wider 

 than long, ^ wider than the neck, the tempora short, broadly 

 rounded ; eyes moderate in size but convex and prominent. An- 

 tennae about ^ as long as the body, quite strongly incrassate to- 

 ward apex, the club not distinct ; second joint obconic, nearly 

 twice as long as wide, slightly thicker but much shorter than the 

 next two ; three to six equal in width ; three to five distinctly 

 elongate ; sixth shorter and but very slightl}^ longer than wide ; 

 seventh more than \ wider, subquadrate, as long as wide ; eighth 

 \ wider than the preceding, conic at apex, transversely truncate 

 at base, slightlj'' wider than long ; ninth nearly ^ wider than the 

 eighth ; eight to ten increasing rapidly and evenly in width, 

 similar but successively more transverse ; ninth ^, tenth nearly |- 

 wider than long; eleventh rather narrower than the tenth, gradu- 

 ally; pointed and narrowly ogival almost from the base, a little 

 shorter than the two preceding. Prothorax not quite as long as> 

 wide, nearly ^ wider than the head, swollen and arcuate at 

 the sides anteriorly, broadly constricted toward base, with two 

 small and approximate fovese at the middle near the base and a 

 larger one at each side less basal, also with a few punctures lat- 

 erally toward base. Scutellum angulate behind. Elytra elongate, 

 gradually, rather acutely pointed behind from basal f , nearly ^ 

 longer than wicje, ^^ times as long as the prothorax and f wider,, 

 broadly rounded and convergent at the sides toward base, the 

 basal margin broadly, feebly sinuate ; basal foveas obsolete, the 

 impressions very small, feeble and basal ; suture not modified. 

 Legs slender ; anterior femora moderately, the other four feebly^ 

 clavate; tarsi slender and filiform; first four joints of the pos- 

 terior rapidly decreasing in length, the first much longer than the 

 second. Length 1.15-L2 mm-.; width 0.45-0.52 mm.
