Key to the species. 



A. Throat metallic-red, breast metallic-green. 1. C. rubinea. 



B. Chin black, throat metallic-green, upper part of breast dark rufous. 2. C. aurescens. 



The style of coloration in these two species is very different, and by some has 

 been deemed of sufficient importance to place them in separate genera. In their 

 structural characters, so far as known, they agree, and for the present at all events 

 it is far better to leave them in the present genus. They are closely related to 

 Ph^eol^ma and lead on to Iol^ema.
