Oblong-elongate; pronotal and elytral markings extremely variable. Head: frontal horn narrows to apex, apex rounded or truncate; depressed between eyes; vertex and frons impunctate; clypeus micropunctate. Antennae: antennomere 1 robust, thickened, with projection on inner apical margin, flattened ventrally, projection reaches to near apex of 2; 2 cylindrical, short, 1/2 length of 3; 3 cylindrical, longest, as long as 1 and 2 combined; 4-7 each subequal in length; 8-10 transverse, wider and shorter than preceding; 11 rounded at apex; 1-10 with scattered setae, 11 setose.

Scutellum: elongate triangle; alutaceous. Elytron: oblong, parallel; apices cojointly rounded; punctate striate; lateral and apical margins smooth; humerus rounded, not produced; punctures moderately impressed; rows tend to coalesce at apex; elytral length 7.0-9.1 mm; elytral width 4.3- 4.4 mm. Venter: pro- and mesocoxae large, globular; prosternal process acute at apex, expanded behind procoxae. Leg: tibia broadly expanded at apex; pro- and mesotibiae toothed along apical margin; metatibia with row of stiff setae on apical margin; femur sparsely punctate. Total length: 10.1-11.3 mm. Larva. (from Maulik 1931). Total length 9–13.5 mm. Total width 5.5–7.0 mm. Body flat, upper surface somewhat convex longitudinally; sides expanded into interlacing flaps which have a fringe of fine setae; ovoid. Head: covered from above by two overlapping expansions; epicranial lobes bifurcate; antennae well developed, three segmented; mandible tridentate; maxillary palps with two segments; labial palps with one segment; four ocelli placed near outer margin of each antenna; legs widely separated; spiracles visible from above, spiracle 8 larger than others.
