A larger insect than C. rufiventris and C. hydrophola. There is no constant differ- 

 ence between the three in their elytral markings ; but C. mellyi is always recognizable 



by the short labrum, the coarsely punctured prothor 



episterna, and the brassy 



piceous posterior trochanters, the last-mentioned organs in the other species being clear 



red like the abdomen. 



In his description of C. mellyi Chaudoir describes the head and thorax as brilliantly 

 metallic. None of the numerous examples from various localities that I have been able
