Male. Upper surface of head, thorax, and legs dark brown : Less 

 densely hairy and hind femora less swollen than in C. americana. 

 Cheeks more or less rufous. Abdomen wholly rufous, and under 

 surface of legs spotted with rufous ; antennae and tarsi luteous. In 

 the darker specimens the legs are wholly reddish brown beneath, 

 and the abdomen is purplish above at the base. Wings as in C. 

 americana. 



* This species will probably prove to be a North- American insect, and is 

 perhaps a variety of G. ulmi. .Many writers regard all the North-American 

 Cimbices as varieties of one species. 



t Probably a variety of the female of C. violacea.
