The fragmentary specimen is exposed on a side view, witli head, front 

 of prothorax, and all the legs gone, and the elytra a little bi'oken. The pro-

 in close proximity to the sutural and outer edges ; the other costjB are 

 obscure, slightly elevated, rounded, broken to a greater or less extent into 

 raised points ; midway between the first and second prominent costse (count-
