Male. — Unknown, 



The female of C. texana Scullen is very close to the female of C. 

 clypeata clypeata Dahlbom but the former may be distinguished from 

 the latter species by the form of the clypeal process. The female also 

 resembles the female of C. aegualis aegualis Provancher in general 

 form and color but the clypeal processes are quite different.
