 alutaceous, front remotely punctate. Prothorax as long as wide, moderately 

 narrowed anteriorly, but not constricted at the apex, broadly rounded on the 

 sides, about as wide at middle than at the base ; disc more remotely, sides densely 

 and more coarsely punctured, filiform scales sparse on the disc, more dense on 

 sides, median smooth line almost entire, distinct; prothoracic lobes feeble, in- 

 distinct. Elytra less than one-third wider at the base than the prothorax, hu- 

 meri prominent, sides slightly rounded, impressed behind the latter; strise 

 deeply impressed, punctures distinct, not very remote, interspaces rather nar- 

 row, equal, suberect setse very small. Presternum deeply emarginate with ante- 

 coxal ridges; thighs rather strongly clavate; tibiae slender, straight, posterior

 beyond, subcarinate in almost its entire length; female very slender, nearly 

 equal in thickness throughout, shining, finely punctured with a few scattered 

 scales near its base; scrobes commencing two-fifths from the apex in the %, and 

 one-third from the base in the 9 ■ ^'^ ntennse slender, first and second joints of 

 funicle elongate, former about one-fourth longer than the latter; clava small, 

 not densely pubescent, basal joint subglabrous. Prothorax about as long as wide, 

 a little narrower at the apex than at the base, broadly rounded on the sides and 

 not constricted at the apex; surface densely and rather finely punctured, dorsal 

 line entire, not quite reaching the base; prothoracic lobes feeble. Elytra nearly 

 two-fifths wider at the base than the prothorax ; humeri rather prominent, sides 

 parallel for two-fifths their length, then gradually narrowed to the apex, striae 

 distinct, distantly punctured, humeral spot and very short basal vitta on the 

 third interspace, which is widened at base, whitish. Prosternal emargination
