Head as wide as prothorax; prolonged anterior
portion of clypeus corneous, posterior half planate, punctate; frons
subvertical. with a median groove; sulcus with clypeus obscure, glabrous in
anterior and punctate posteriorly; strongly raised between antennal insertion,
acutely concave side to side; vertex with a deep median groove flanked by few
short carinae by its side between upper eye lobe; gula transversely rugose;
neck coarsely punctate. Antenna shorter
than body; fairly reaching 1/3 of elytra in 
; scape short, wider at apex,
slightly produced ectoapically, coarsely but shallowly punctate; segment 3 only
a little longer than scape, thicken at apex; 4+5 combined as long as 3; 4 - 10
of the same length, dilated, laterally carinate, cross section of each segment
4-sided or squarish; last segment acuminate. Prothorax squarish; strongly constricted at base; weakly narrow and
depressed at apex; apex and base transversely rugulose; centre of pronotum
dilated, elevated; disc coarsely punctate, punctures unevenly distributed,
subglabrous medianly, latero-posterior puncto-striate; side with a blunt
tubercle a little behind middle; fore intercoxal process .sunken between coxae,
gradually dilated at posterior. Scutellum
triangular; large; semi-impunctate. Elytron
4.8 X as long as broad; fairly wider than lateral tubercle of prothorax;
base transverse; disc convex, closely puncto-striate, punctures coarser near
base, becoming finer towards apex; 1/5 of apex finely punctulate. Legs : fore
femora short, fusiform; mid femora subclavate; hind femora longest, 2 X as long
as the middle pair, peduncle-clavate; all femora sparsely punctulate; fore and
mid tibiae setaceous at apex; hind tibiae subglabrous and sparsely punctulate;
greatly widen at apex.
