Vertex smooth, impunctate; front broadly sulcate, piceo-fulvous; interocular space 
rather strongly produced, obtuse. Antenne less than half the length of the body, 
robust, subfusiform, attenuated at the base and apex; two lower joints stout, equal,

long; sides subangulate, straight and nearly parallel from the base to the middle, 
thence obliquely converging towards the apex; transversely convex, depressed behind 
the middle; coarsely and closely punctured. FElytra broader than the thorax; sides 
parallel, slightly dilated towards the apex, the latter rounded, conjointly subangulate- 
emarginate at the suture; each elytron with eight, at the extreme base with nine, rows.

with the fourth and sixth interspaces moderately, costate. 
2. Apices of the elytra conjointly rounded, the sutural angle entire.
