scarcely broader than the thorax, shoulders rectangular, 

 anterior angles rounded ; sides subparallel at the base, 

 rounded and obliquely converging behind the middle, the 

 apex broadly rounded ; disk coarsely and deeply punc- 

 tured, the punctures arranged in longitudinal rows ; inter- 

 spaces thickened, rugulose, eacli elytron near the suture 

 Avith an ill-defined longitudinal costa ; outer margin coarsely

Hab. — Nagasaki, Japan ; also Oo Oo Bay, Coast of 

 Tartary (Mr. A. Adams). 



Very close to C.ferruginea and agreeing in most of its
