 Truman, Cockerell, Kolbe). 



Note. — Specimens collected by the writer at Saratoga Lake, N. Y., Aug. 15, 

 1889, have, in the males, the apical half to two-thirds of 3-6 black, the two 

 branches of the sup. app. of nearly equal length, and, in the females, the post- 

 ocular spots circular, unconnected. The writer believes them to be merely a 

 variety of civile, and Dr. Hagen agreed with this opinion. — Civile often has the 

 postcostal cross-vein as nearly under the first antecubital as in E. durum.
