20 i Canadian Arctic Expedition, 1913-18 



FAMILY NYMPHALID^. 

 Argynnis bischoffi Edw. 



Argynnis bischoffii Edw.: Trans. Amer. Ent. Soc, III, 189, 1870. 



A single specimen taken on August 7, 1904, at Mayo lake, Yukon Territory 

 (J. Keele) was determined by Fletcher as A. eurynome Edw., and has been 

 recorded under this latter name by Keele 1 . Several years ago I submitted 

 this specimen to Dr. Skinner, who reported that it was a boreal form of A. 

 eurynome Edw. Personally, however, I prefer to place the specimen under the 

 name bischoffi Edw., which was described from Alaska, opposite Kodiak. In 

 the description the spots on the underside are referred to as being pale, not 

 silvered. The above specimen (a male) which is in the Canadian National 

 collection, has silvered spots. Edwards, however, has remarked that the species 

 occurs at Sitka, Alaska, in both silvered and unsilvered forms, and figured a 

 specimen of the former 2 . Barnes and McDunnough 3 in discussing the species 

 briefly point to the fact that the name in sens, strict, can only apply to the 

 unsilvered form.
