tenuicorne vs bicolor
Arnett's 1953 key, if it's of any help:
...
6. Three distal antennal segments together approximately 1.5 mm long => C. bicolor
- Three distal antennal segments together barely over 1 mm long => 7
7. Male with bifurcate process of third visible abdominal sternite long and fingerlike; female with apical abdominal sternite shallowly and narrowlj' emarginate; color of female black to testaceous => C. tenuicorne
- Male with bifurcate process of third visible abdominal sternite shorter, more triangular; female with apical abdominal sternite deeply emarginate; color of female reddish testaceous with elj'tra and metasternum black. => C. vandykei

 
bicolor
Measurement of three distal antennal segments clearly 1.5mm or slightly longer. Can you move to C. bicolor....

Thanks,

Gary
