Body subovate, rounded. Colour red-brown ; head, the five 

 apical segments of the antennae, prothorax and legs, black ; the 

 tibiae and tarsi may be more brownish than black ; the six basal 

 segments of the antennae are yellow-brown. 



Head: vertex convex, impunctate ; eyes large. Antennae just 

 one millimetre shorter than the length of the body ; first segment 

 elongate, club-shaped, second almost as long as, and thicker than, 

 the third, which is slender, fourth and fifth, which are equal to

than the preceding segments ; from the seventh the segments 

 become much larger, thicker, and opaque. Prothorax broader than 

 long, front margin straight, sides straight, anterior and posterior 

 angles thickened, the former more so, and possessing seta-bearing 

 pores, basal margin gently rounded ; surface convex from side to 

 side, finely and not very closely punctate, the punctures showing 

 a tendency to arrangement in transverse rows towards the base. 

 Scutellum triangular, smooth, impunctate. Elytra hardly broader 

 at base than prothorax, but broadened immediately behind, humerus 

 raised, convex ; each elytron has the following well-arranged rows 

 of deep punctures : a short scutellar row, terminating just before 

 the middle of the elytron, and ten other rows at almost regular 

 intervals ; the rows converge towards the apex ; counting from
