in front: head and prothorax at bottom minutely, densely and 

 rugosely pnnctvdate, and with scattei-ed small setiferous tubercles: 

 intervals of elytra with scattered small punctures, mixed with 

 minute setiferous tubercles; first costa strongly continued along 

 the base: prosternal process rugosely tuberculate. Length 5 

 lines.

Pterocotna seniicarinata, n. sp. 



Very broadly ovate, elytra almost rotundate: black, a little 

 shining: labrum emarginate in front: head sparsely punctured, 

 and with small setiferous tubercles clustered above the eyes: 

 prothorax with a few flattened tubercles on the disc, which are 

 distinctly umbilicate; on each elytron a single costa composed 

 of flattened tubercles, placed half way between the suture and 

 shoulders, and not extending more than half down the elytra 

 from the base ; between this and the side are indications of two 

 other costa;, the outer one most distinct, these are composed of 

 very small distant setiferous tubercles, the marginal carina is com- 

 posed of a double row of closely set bluntish tubercles ; no 

 trace of pubescence on the intervals, but they have a few very 

 minute setiferous tubercles near the base; prosternum coarsely,
