Although the description and figure of Blessig do not exactly 

 fit witli regard to the outline of the thorax and the sutural apex of 

 the elytra (especially in the female), there can be little doubt 

 that the two namies refer to the same species.

Blessig describes his species from a single example found at 

 Port Mayj on the coast of Manchuria ; his description and figure 

 agree with the Japanese species, w hich is not generically diff"erent 

 from jD. cohimbina, Serv., the type of the genus. Blessig men- 

 tions as a chief character of Bistenia silky hairs on the underside 

 of the antennae ; but these do not exist in B. columbina, at least 

 in the examples I have examined, and cannot besides be a generic 

 character, as they are present or absent in species most closely 

 allied in all other respects.
