This species is difficult to place under the system I have adopted 

 in tabulating the Chalcopteri, as the width of its prothorax in 

 front is just about ^ of the width at the base. Such difficulties 

 are inevitable in any tabulation of a large number of closely allied 

 forms. I have decided to place this species among those with the 

 prothorax less narrowed anteriorly. If it were placed among 

 those with the prothorax anteriorly more narrowed it would stand 

 beside C. modeshts, which has eyes much less distant from each 

 other and the punctures of the lateral series on the elytra much 

 larger. 



Compared with C. cuj^ripennis the present insect has eyes a 

 little less widely separated, prothorax less transverse, seriate 

 punctures of elytra not much different, interstices much less 

 punctured (all but impunctate), basal joint of hind tarsi more
