(Delaware Water Gap, Hummelstown, Inglenook, Montgomery Co., 

 Pittsburgh, and Spring Brook); Prince Edward Island (Brackley 

 Beach in Canadian National Park) ; Quebec (Cap Rouge, Montigny, 

 and Pentecost); Rhode Island (Coventry); South Carolina (Green- 

 ville); Vermont (Laurel Lake near Jacksonville); Virginia (Dead 

 Run in Fairfax Co., Falls Church, Glencarlyn, Great Falls, and 

 Virginia near Plummers Island) ; West Virginia (Cheat Mt. at 2,000 

 ft. in Randolph Co.); and Wisconsin (Madison). 



Dates of capture are from rather early spring to mid-summer. In 

 most of its range the species is commonest in June and late May. In 

 the Carolinas it emerges in April (captures April 2 and 20 at Green- 

 ville, S. C. and April 19 and 20 in Wake Co., N. C). In the vicinity 

 of Washington, D. C. the first emergence is in late April and early 

 May (captures April 24 at Washington, D. C. and May 4 at Glen- 

 carlyn, Va.). At Ithaca, N.Y. first emergence is in mid-May (cap- 

 tures May 8, 14, and 19). Adults have mostly disappeared by the 

 end of June but in the northern part of the range a few remain into 

 July, and there is one capture in August (August 21 at Ames, Iowa). 

 In our own collecting, we have found the species in rather open, 

 moderately dry, deciduous woods. 



This species occurs in the Alleghanian and Carolinian faunas. 

 It is adult from mid-spring through early summer.
