Antenna shorter than body, extended to half of elytra; 2 - 4 cylindrical, slender; 5 - 11 subelavate, complanate; scape puncto-striate; 3 twice as long as scape; 4 a little longer than 2; 5 bilaterally widen to apex; 6 - 10 squarish; 11 rounded at apex. Prothorax longer than broad; depressed dorsally; apex transversely constricted with parallel sides; base also constricted but sides convex; area between apical and basal constriction swollen, broadly bilobe posteriorly with convex margin; swollen portion on pronotum coarsely puncto-striate. Elytron 6 X as long as broad; parallel-sided at basal half, slightly wider at 2/5 from apex, gradually conjointly curved at apex; disc very flat, external margin sinuate, coarsely puncto-striate to granulo-punctulate especially near the tip. Legs : hind femora disproportional lengthen, peduncle curved, a little more than 2 X the length of clavated apex which extended beyond elytral apex; peduncle of mid and hind femora carinate.
