  One 
  male 
  from 
  Georgia. 
  More 
  robust 
  than 
  the 
  preceding, 
  almost 
  intermediate 
  in 
  form 
  

   between 
  the 
  male 
  and 
  female 
  of 
  C. 
  bicolor. 
  The 
  antennae 
  hardly 
  reach 
  beyond 
  the 
  base 
  

   of 
  the 
  thorax 
  ; 
  the 
  posterior 
  angles 
  of 
  the 
  thorax 
  are 
  not 
  distinctly 
  carinated 
  : 
  the 
  front 
  

   is 
  somewhat 
  more 
  convex 
  than 
  in 
  the 
  other 
  two 
  species.
