 I'rotlioru.r traiisvor^ie, jiradnally narrowed anteriorly and 

 clothed with small scales inters|)crsed with larger ones ; u 

 subtrianf^ular dark patch extends from tlic anterior niarj^in, 

 narrowing to the centre; anteriorly transversely dej)ressed, 

 the basal extension sonu'what acnte. Scutellum elongate 

 and rugose. Elytra slightly broader and twice as long as 

 the prothorax, the strijc furnished with uniscriate subrcct- 

 aiignlar impressions, the interstices subconvex, rugose basally, 

 coarsely and irregularly punctured, the first interstices with 

 iiniseriate, the remainder with more or less irregular biseriate 

 stumpy scales, wliicli become uniseriate towards the apex, the 

 scales on the lateral interstices are longer and more slender; 

 tli(^ sntural edges are furnislied with rows of very minute 

 hairs; the elytral base is transversely rugose with a creiiate 

 margin, but not overlapping the prothorax ; the second and 

 third interstices terminate in a strong tubercle, a similar but 

 smaller tubercle being visible at the junction of the Hfth, 

 sixth, seventh, and eigiith interstices; there arc two or three 

 tubercles on the third and fifth interstices on the declivity. 

 The female is slightly larger than the male, and the elytral 

 tubercles arc much smaller and indistinct, there is also a faint 

 longitudinal median elevation on the front of the latter.

 to the front ; anteriorly transversely rugose to the ccntr.\ 

 which is not raised, posteriorly scantily punctured, the 

 punctures rather more marked near the base, which is sligjitlv 

 sinuate. Elijtra ecpial in brcadih anil a third longer than 

 the prothorax, o])scnrely striate basally and more or less 

 transversely rugose, the interstices flat, with pilil'erous 

 punctures, to about the centre, and then with piliferous 

 tubercles to the apex ; the declivity abrupt and opaque, tlie 

 striie very faintly punctate ami broad ; viewed dorsal ly the 

 apex is seen to be furnished with tul)erclcs, which are con-
