Note. — The above name must be regarded as provisional, as in all 

 probability it is synonymous with DoUeschall's C. aureostriatus, from 

 Amboina. The only point on which his description does not correspond 

 is that he makes the abdominal banding apical, but the hmder fringe of 

 light bristles masks their position, and it is easy to be mistaken on such 

 a point, unless one regards its determination as a matter of importance. 

 Pending the receipt of specimens from Amboina, or exammation of 

 DoUeschall's tj-pes, C. Japonicus must, liowever, stand as a provisional 

 new species.
