fuscous ; the apex fuscous, with an orbicular, yellow spot ; poste- 

 rior wings cinereous, the anterior margin and pterostigma yellow. 

 Male and female. 



Var. Anterior wings less spotted, the basal stripes shorter, the 

 disk spotted, and the apex with an incurved band, which has the 

 open side inwards, fuscous. 



Hob. St. Lawrence River, Canada ; Washington ; Virginia 

 (Osten Sacken) ; Maryland ; Niagara Falls ; immensely common 

 upon the foliage of trees on Goat Island (Uhler). 



I possess a very small specimen from Washington, only 11 mil-

 wings are almost altogether confluent.
