Genitalia : <S. Process of barpe situated proxiiuuUy of m ist distal point of 

 apex, the apical edge of the harpe being rotnndate-angulate ; oblique dovsal edge of 

 barpe bearing at least two strong hooks at the upper corner, and several prominent 

 teeth near these hooks, there being occasionally also some teeth at the ventral 



edge ; individual variability considerable. ?. Process in front of vaginal orifice 



lanceolate, pointed, rarely bidentate at tip; dentate lateral flaps standing farther 

 anad than the orifice. 



For early stages see Edwards and others (see literature below). 



One brood in the north, two or more in the south ; the spring specimens 

 (from hibernated pupae) of the southern districts are smaller than the summer 

 specimens. 



Hdb. Alaska, British Columbia, eastwards to Newfoundland and southwards 

 to Florida and Texas, not in the Pacific (and Rocky Bits.) district of the United 

 States. 



Two geographical forms, southern spring specimens somewhat resembling the 

 small northern form, but being easily distinguishable by the much narrower black 

 .abdominal border to the hindwing. The geographical boundary line between the 

 northern and sonthern forms is in the lake district, and it is probable that the two 

 forms completely intergrade in Southern Canada. Observations on this point are 

 wanting. As far as we could, we have kept separate the literature on the two forms. 

 It is to be hoped that in future local records of this species it will be expressly 

 stated by the authors which of the two forms occurs, this being especially desirable 

 in records from southern Canada and the northern districts of the United States.
