This is a very elongate species resembling C. cylindricus in 



outline, but being less convex it does not appear so cylindric. 



It is an extremely isolated type, the evenly distributed strong 



puncturation of its prothorax and the well-defined puncturation 



(scarcely at all obscured by wrinkles) of the underside being 



characters almost as unusual as the peculiarly elongate form. 



The interval between the eyes is about a third narrower than in 



G. cwpripennis, and the elytral puncturation (both of the series 



and the interstices) is almost as in that species.
