separated for the third antennal article longer than the second and the moderately emarginate apex of elytra.

Description. – Female.

Moderately shiny.

Coloration. – Head, sides of pronotum, base and sides of elytra, from the sixth interstriae, blackish; the remaining parts brownish; covered with dense, recumbent yellowish pubescence.

Head. – Frons convex, anterior margin regularly curved, simple, directed downwards and just projecting above the clypeus; punctures simple or slightly umbilicate with shortest intervals. – Antennae reaching the apices of the posterior angles of pronotum, slightly serrated from the third article on; second article sub-cylindrical, third sub-conical, 1.7x longer than the second, sculptured as the following, taken together a little longer than the fourth; fourth-tenth sub-triangular, the fourth longer than the following, third-fifth with a vestige of mid-longitudinal carina, the last sub-ellipsoidal (Fig. 36).

Pronotum. – 1.12x longer thanwide, widest at the apices of the posterior angles, strongly convex, abruptly sloping at sides, nearly vertically at base with a vestige of shallow mid-longitudinal depression on the basalslope;sides from base to the anterior margin regularly and moderately tapering; posterior angles long, acuminate, not divergent, uni-carinate; carina short but sharp and diverging from the lateral margins, the latter complete and visible for the first half in a dorsal view; punctuation regularly distributed, punctures on the disk simple or slightly umbilicate, with intervals on average equal to a little smaller than their diameters and feebly micro-reticulated, towards the base and the sides gradually more clearly umbilicate and with intervals clearly shagreened giving to the surface an opaque appearance.

Scutellum . – Tongue shaped, slightly convex, densely punctured.

Elytra. – 2.7x longer than pronotum and 3x longer than wide, convex, rather flattened on the central disk; sides sub-parallel for the first half then very gradually tapering to the apices, the latter very scarcely emarginate ( Fig. 48); striae regularly marked and punctured, interstriae flat with wrinkled surface.

Size. – Length 10.5 mm, width 2.5 mm.

Male. – Unknown.

Etymology. – The name is derived from the country where the species was collected, Sikkim.
