ing outward, 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 surmounted by triangu- 

 lar, 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 me- 

 dian nervule, near its extremity, form a considerable ochraceous space 

 more or less mixed with reddish scales ; but the space between the 

 broad band and the outer border is further occupied by a curving row 

 of round blackish spots, with intermingled reddish scales, bordered del- 

 icately with ochraceous ; and also by a narrow, nearly straight band, 

 slightly bent and less conspicuous in the middle, where it touches 

 the outer border of the broad band, and formed of pale rosaceous 

 scales, whitish toward the extremities. 



Body covered above with greenish-brown hairs, toward the extrem- 

 ity fulvous ; beneath ochraceous ; palpi with mingled ochraceous and 

 black hairs below, mingled fulvous and black above; stalk of antennas 

 white below, black above, with white annulations ; club of antennas 

 black, bright fulvous at the tip. Expanse of wings 38.5-43.5 mm. I 

 have only seen males. 5 specimens. Fort Simpson, Great Slave 

 Lake, and Fort Rupert's Land, Eastern coast of Hudson's Bay, Brit- 

 ish America (W. H. Edwards). Mr. Crotch obtained specimens at 

 Lake Labache. I have never seen specimens from Labrador. 



This species is very closely allied to, and representative of B. Mon- 

 tinus Scudd., from which it differs principally in the following partic- 

 ulars ; the color of the upper 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, discern- 

 ible ; the submarginal 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 arcuate 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. In j>revious remarks on B. Montinus, I have
