Tliis species is extremely like .some \'arieties of C. eupripennis, 

 Hope, and may possibly pi'ove to be itself a variety of that 

 insect. It differs, however, from all the examples I have seen 

 that I can refer to eupripennis in two characters that seem to be 

 important, viz., the structure of the head and the sculpture of the 

 elytra. In eupripennis (and in most Ghalcopteri) the forehead is 

 fUvided from the clypeus by a fine suture which passes (arched 

 slightly hindward) immediately in front of the antennal tubers, 

 in front of which stands the clypeus appearing from its convexity 

 to be a little tumid ; in clypeatus, however, the space immediately 

 in front of the clyi)eal suture is a flat continuation of the plane of 

 the clypeus, which space is strongly arched forward in front, and 

 ill froat of it the clypeus becomes suddenly tumid with its hinder 

 side deeply concave where the flattened space mentioned above 

 cuts into it. As regards the sculpture of the elytra, I have not 

 seen among the examples I refer to cup>ripennis any in which the 

 punctures of the longitudinal series and those of the intei'stices 

 are so nearly alike as they are in this insect, especially near the 

 suture where the punctures of the series are scarcely distinct 

 from those of the interstices ; whereas in euprijjennis (although 

 the seriate and interstitial punctures are undoubtedly less distinct 

 from each other than in the majority of Ghalcopteri) even the 

 series nearest the suture is perfectly apparent to a casual glance. 



The shape of this species is diflerent from that of most of its 

 congeners, though agreeing with that of C. cuprijjennis and 

 several others. If it be looked at from tlie side it will be seen 

 that the highest point in the curve which forms the upper 

 outline is exceptionally near to the base of the elytra, so that the 

 posterior declivit}'- is very gradual indeed, and begins far in front 

 of the middle. The puncturation of the prothorax is very faintly 

 impressed and not close, but it is not particularly tine as compared 

 with that of some Ghalcopteri.
