5. B. boisduvali Duponchel. 



One specimen only was obtained. I cannot agree with Elwes 

 in treating this form as a mere variety of B. chariclca Schnei- 

 der. 



6. B. pales Schiffermueller, var alaskensis var. nov. 



Unfortunately, the collection contains only a single specimen of this 

 interesting form. It differs widely upon the upper surface from specimens 

 of B. pales coming from various European localities and contained in my 

 collection. It comes nearer in general aspect to the variety named gen- 

 erator by Staudinger, coming from the Pamir and Transalai regions of 

 Asia, but is smaller. The fuscous area of the basal portions of the pri- 

 maries and secondaries is reduced, extending outwardly only to the mid- 

 dle of the cell, and the entire wing beyond this is bright reddish fulvous, 

 with the characteristic lines and spots narrow and fine. The under side 

 is marked much as in typical pales.

7. B. freija Thunberg. 



There is an interesting series of this species, mostly females, 

 all more or less worn, showing that, when obtained, they had 

 already been long upon the wing. If collections could be 

 made in the locality where they were found at an earlier date, 

 no doubt better specimens could be obtained.

S. B. polaris Boisduval. 



The collection contains one good pair and one badly worn 

 female of this species. All of the specimens agree perfectly 

 with typical examples obtained from European localities and 

 various points in boreal America.
