Tliis species bears some resemblance to C. asilica, Fall., of 

 Europe. It closely resembles my 0. dentata, but is at once 

 differentiated by the absence of the tooth-like process below the 

 hind femora. Other points of difference lie in the facial bump, 

 which is more gradual and less prominent than in dentata, and in 

 the reddish-brown 2nd abdominal segment.
