KELLICOTT. 37 



lines forming the mid-dorsal thoracic stripe are 

 separated by pale yellow, the dorsal patch on 8 is 

 longer, reaching more than half the length of the seg- 

 ment, and the whole dorsum of 10 is blue. 



The males are separated from those of aspersum 

 by coloration of the abdomen. In the latter species 

 one-half of 7 and all of 8 and 9 are blue, while in 

 traviatum only 8 and 9 are blue. 



The females of aspersum have a blue patch reach- 

 ing three-fourths the length of 7 on each side, and a 

 round spot on each side of the base of 8, blue, while 

 traviatum has 8, 9 and 10 blue with the exception of 

 the dark green basal patch on 8. 



The species has been taken at Cincinnati (Dury) 

 and at Akron in June. Seemingly common in various 

 parts of the State.
