Rostrum elongated and triangular, broad, plane, deeply excised 

 from the head ; eyes elongated, flat with a strongly developed ridge 

 above ; prothorax moderately covered with light-brown scales, and 

 with the sides armed with a long conical spine, covered with sharp 

 tubercles, and having in the middle a wide groove (the walls of which 

 are much raised anteriorly), disconnected in the centre and hardly 

 reaching the base ; this groove contains a fine median ridge ; elytra 

 elongated, moderately convex, retuse posteriorly, densely granulose 

 with the suture sub-tuberculated, and two series of flat, rounded 

 tubercles on each elytron ; they are moderately covered with scales 

 forming regular longitudinal series of ochraceous patches — eight on 

 each side from the suture to the epipleura, — those situated between 

 the larger series of tubercles are very conspicuous and larger than the 

 others ; pectus and lateral sides of abdominal segments ochraceo- 

 squamose ; legs very rugose, bristly ; tibias covered with short spines 

 more developed in the hind ones, where some* of these are longer than 

 the others and very conspicuous.
