Oblong, covered with minute greyish and brownish scales ; head 

 broad, a small round superciliary ridge, front irregularly punc- 

 tured ; rostrum narrow, with a double row of six punctures at the 

 base ; prothorax convex, rounded at the sides, and about as long 

 as broad, the apex slightly produced with a transverse impression 

 behind it, the disc roughly punctured in the middle, punctures at 

 its sides smaller and less approximate, the sides and middle striped 

 with brown ; elytra not twice the length of the prothorax, disc 

 seriate-punctate, each with three rows of tubercles, all conical and 

 gradually larger to the proclivity, the interval between the first 

 and second rows with a double row of punctures, the inner and 

 outer rows with three tubercles each, the intermediate with five, 

 the last of this row much the largest, on the declivity one 

 mammilliform and two or three smaller tubercles, the deflexed 

 sides with numerous scattered punctures ; first abdominal suture 

 nearly obsolete ; legs dotted with long setse or hairs. 



The intervals between the rows of tubercles have a 

 brownish hue, but the outer stripe is dark brown. A
