NYMPHALIDAE: ARGYNNIDI. 1807 



parallel in general direction to the inner border; the narrow outer border of the wing 

 is pale cinnamon red, resting upon which is a row of transverse, ovoid, white spots sur- 

 mounted 1)}' triangular, somewhat sagittate spots of (sometimes blackish) cinnamon 

 red ; between these and the broad band the space is pale cinnamon red with scattered 

 ochraceous scales, which, on either side of the last median nervule, near its extremity, 

 form a consideratile ochraceous space, more or less mixed with reddish scales; but the 

 space between the broad band and tlie outerborder is further occupied by a curving row of 

 round, blackish spots, with intermingled reddish scales, bordered delicately with ochra- 

 ceous ; and also by a narrow, nearly straight band, slightly bent and less conspicuous 

 in the middle, where it touches the outer Ijorder of the broad baud, and formed of pale 

 rosaceous scales, whitish toward the extremities. Expanse of wings, 38.5-43.5 mm. 

 Described from males only. 



This species is very closely allied to B. montinus, from which it differs principally 

 in the following particulars ; the color of the upiier surface is not so deep ; at the base 

 and along the subcostal interspaces of the hind wings it is not so dusky ; upon the 

 lower surface the markings of the apex of the fore wings are much more conspicuous, 

 as is also the broad mesial band of the hind wings, which here is of a very different 

 tint from the base, while in B. montinus a difference is seldom, and then but slightly, 

 discernible ; the snbmarginal rows of sagittate spots and of round spots are also much 

 more conspicuous, being frequently very nearly obliterated in B. montinus; the space 

 between the arcnate row of round spots and the mesial band is much tinged in B. freija 

 with rosaceous scales, giving it a peculiar appearance; these are present only in a 

 slender band in B. montinus, and then are nearly obsolete ; the darker parts of the 

 outer border of the hind wings are darker than in B. montinus, being there somewhat 

 pale cinnamon red, while here they are rather of cinnamon brown. 



Freija is a circumpolar .species in the strictest sense, being found on the 

 northern shores of both worlds, and in each extending southward to the 

 habitable zone. In the Old World its home stretches from Norway and 

 Lapland to eastern Siberia, and in Russia it extends southward to the 60th 

 degree of latitude. In the New AYorld it occurs from Alaska to Labrador, 

 where it is found upon both the eastern and the western coasts, and in the 

 Rocky Mountain region extends as far south as Lake La Hache (Crotch), 

 and Crow's Nest Pass, west of Ft. McLeod (Geddes). It is said by 

 Edwards to occur in Colorado, but the specimens obtained there by Mead 

 (to which he probably refers) belong to the next species, while those from 

 Port Ai-thur and Nepigon north of Lake Superior, referred by him to 

 chariclea, belong here. 



To judge from the captures north of Lake Superior it is a late species, 

 flying late in Augiist and early in September, or at the very close of the 

 season in that place. Evidently winter must be passed by the caterpillar 

 just from the egg.
