There is indubitably a very strong facial appearance of 

 great similarity between the two insects in question, but 

 the following differences are, I think, quite sufficient to 

 prove their non-identity. The general appearance of 

 C. Buckley i, S , is somewhat more shining, the mandibles 

 are shorter and more robust, broader at the base, being 

 also more arcuate ; the joints of the antennae, between 

 the funiculi s and the clava, are cylindriform, instead of 

 flat, as in C. Luxerii; they are also longer, consequently 

 the scapus is visibly more elongate, the dilatation at the 

 extremity of the sixth joint is not quite so pronounced, 

 the seventh or basal joint of the clava (which, according 

 to the author, is composed of four joints) is considerably 

 longer. The clypeus in C. BucMeyi is, moreover, bino- 

 dose at the extremity, whilst in the allied species it is 

 simple. The head is much broader, more excavated in 

 front, with the anterior part more emarginate. The 

 prothorax is of a totally different form, being prominently 

 wider, and rounded at the sides, with the posterior angles 

 considerably less acute; and, finally, the elytra are 

 slightly longer, with the humeral angles acute instead of 

 being rounded.
