The rostrum has the lateral ridges elevated in the middle, 

 giving it a convex appearance. The forehead is round. The 

 thorax is covered with minute setigerous tubercles. The elytra, 

 which are narrow and parallel sided, are punctured in irregular 

 rows, the punctures being large and each accompanied by a 

 setigerous granule ; the interstices, also irregular, are marked by 

 distant minute tubercles. The setge are all of a pale yellow 

 colour. 



This insect is probably from the northern interior.
