Calpazia vermicularis PASCOE

Head black, tinge with brownish castaneous near base of mandible, labrum and clypeus; prothorax and elytra black; antennae brownish castaneous with sparse ashey pubescence; pubescent on elytra argentate, irregularly arranged, in small scattered patches; disc of elytra with 2 oval glabrous impubis patches behind middle; undersurfaces pitchy with moderate ashey pubescence; femora fuscous; tibiae castaneous.

Head exserted; mandible carinate at middle of dorsal; frons oblique with 2 crescentric sulci side of median that united with median groove between antennal insertion; antennifer strongly deplanate; a short median groove behind the latter follow by a deep pit at posterior margin of upper eye lobe; lower eye lobe large, triangular with the anterior boarder slightly notched; gula raised between eye, concave producing a deep wide sulcus with ventral part of neck. Antenna longer than body in , segment 8 almost reaching elytral apex; shorter in , terminal segment extended to posterior margin of impubis blotch; scape short, not reaching apical margin of prothorax, dorsal surface canaliculate near base; 3 as long as scape; 4 & 5 subequal, shorter than 3; 6 - 11 strongly complanate; 6 - 10 produced externally and dentate ectoapically in , only feebly anglate ectoapically in . Prothorax a little longer than broad; widest at middle; side concave; apex and base with a transverse groove each; pronotum subpubescent, median oblongly raised with flexuous edge; latero­dorsal rugose; side and ventral of prothorax pubescent, not distinctively rugose but more like obscure protuberance; anterior of prosternum with a deep transverse groove and a shallow one behind near to fore coxae; ventral surface roughen, weakly and irregularly carinate; fore intercoxal process wide; posterior end declivent, rounded. Elytron 4.5 X as long as broad; parallel at 2/3 from base, gradually curved at 1/3 from apex or behind impubis blotch; dehiscent at tip; truncation transverse but short; sutural spine distinctive in ; disc with a pointed tubercle side of suctellum; dented or sunken behind scutellum; sutural half flat and planate, marginal half concave; pubescence caespitose into irregular patches, tense to concentrate on outer margin and apex; a impubis patch behind middle, sparsely punctate, punctures different sizes and piliferous; anterior of this patch coarsely but sparsely punctate. Legs : compressed; subfusiform with apex more clavate; external side of femora with a carina each, but more distinctive on middle and hind pair; tibiae linear, very pubescent and setaceous.
