(J. Size moderate. Colour black, elytral granules dark red; 

 sparingly clothed with minute greyish scales; fascicles red; 

 nigro-setose. Head large, convex, hidden by prothorax; rostrum 

 short, thick, rather feebly excavate, ridges flattened, basal sulci 

 well marked; mandibles simple; mentum with a strong triangular 

 gular horn. Prothorax(6 x 6 mm.) widest in front of middle, 

 apex strongly produced, collar-constriction faint, median line 

 obsolete, moderately finely granulate, granules rather larger 

 towards sides, setigerous. Elytra (14 x 8 mm.) widest behind 

 middle, rounded on sides; base feebly arcuate, shoulders moder- 

 ately prominent; apex abruptl}^ rounded, flanged and mucronate; 

 disc irregularly striate, the strise crossed by numerous transverse 

 rugae, interstices rather finely granulate in single series, sutural 

 represented by a row of minute granules not thickened at base; 

 second, fourth, and sixth finely granulate, the fourth and sixth 

 rather irregularly so and barely reaching to base or apex; third, 

 fifth, and seventh interstices more prominent, the granules 

 slightly larger and extending from base to apex. Metasternum 

 feebly concave in centre. Anal excavation deep, not quite 

 reaching to anterior margin of the segment, preanal fossa deep, 

 posterior edge sinuous; fascicles widely separated, situated within 

 the excavation. Forceps rather small, transversely widened at
