In IMaryland this species occurs abundantly in June and July, upon 

 Cralcegus, and I have also found specimens upon Willows as late as the 

 middle of October. Specimens have also been collected near Chicago, 

 and at Rock Island, III, by B. D. Walsh. Others have been sent to me 

 from Waco, Texas, by Mr. Belfrage, and I have captured a few others in 

 Eastern Massachusetts.
