It is not closely allied to any other of our species, though C. rufus, Murray, is some- 
what allied. It varies much in size, but in other respects very little. ‘The unique 
specimen from Guatemala is in a bad state of preservation, and I think may prove to 
belong to another species, as the pygidiumi appears to be rather differently formed. 
C. curvipes is remarkable owing to the large size of the labrum, the division between 
the lobes not reaching to near the base. _ 
§ 9. Mesosternum and metasternum simple; male with the pygidium not covering the 
supplementary segment; margins of the elytra fimbriate (only obscurely so in 
C. floralis). (Species 32-35.)

This name stands in the Catalogues as a synonym of C. pallipennis, Say ; but this is 
not correct. C. floralis has the fimbriz on the margins of the elytra almost absent, a 
more definite punctuation on the elytra, and the pygidium of the female quite simple 
at the extremity (whereas in C. pallipennis it is prolonged, incrassate, and somewhat 
reflexed). The female usually has the surface of the pygidium more or less depressed 
on the middle, but this is variable. The male has a small and slight depression in the 
middle of the last ventral plate just in front of the hind margin, and the hind margin 
is very slightly sinuate on each side, so that there is a slight angular projection in the 
middle: there is a very slight curvature of the hind tibie at the base. 
We have received a great many examples of the species, which varies somewhat in 
size and also in colour, but not very much. 
Reitter’s description is too indefinite to allow his C. luteipennis to be certainly recog- 
nized, but it is probably this one.
