C. zelica Banks is similar to C. compar Cresson in size and coloring 

 but the form of the clypeal elevation will separate the females. 

 No satisfactory characters have been found to separate the males 

 of the two species. No doubt the males of the two species have 

 been confused. The description of the male is based on the type 

 and specimens determined by Banks from the type locality. 



Type^. — The type male and the allotype female of C. zelica B&nks, 

 from Fedor, Lee Co., Tex., June 7 (Beckmann), are at the Museum 

 of Comparative Zoology, Harvard, no. 13773. 



Distribution. — Throughout the Eastern and Central States. 



Prey record. — None. 



Plant record. — None.
