spoken of B. Freija as Argyimis Boisduvalii, by a mistaken identifi- 

 cation. 



Brenthis polaris (Boisd.) 



Upper surface fulvous with black markings ; nervures black except 

 the main stem of the median, which is fulvous bordered with black. 

 Fore wings : a mesial band crosses the wing, composed of three 

 parts ; the first starting from the costal border at a little more than 

 one-half the distance from the base to tip of wing, runs nearly- 

 straight to the upper median nervule beyond its basal curve; it is 

 connected with the costal border by a narrower black band; the sec- 

 ond part consists of a blotch crossing the interspace between the upper 

 two median nervules, as broad as the previous part, taking nearly the 

 same general direction, its outer edge continuous with the inner edge 

 of the first part of the band ; it generally leaves a little fulvous at the 

 extreme base of the interspace; the third part is an equally broad 

 band crossing the next two interspaces, bent at the lower median in- 

 terspace and reaching the submedian nervure; its upper half stands 

 in the same relation to the middle portion of the band as that to the 

 first portion, and its inner edge generally starts at the divarication of 

 the middle median nervule, although sometimes the whole base of 

 the interspace is filled with black; its lower half is continuous with 

 the upper but runs at right angles to the nervures; within the mesial 

 band, and narrower than it, are three black streaks which cross 

 the cell ; the outer borders its termination ; the middle is in close 

 proximity and bent outward in the middle ; the last is straight, lies mid- 

 way between the base and termination of the cell and does not reach 

 the median nervure ; below the median nervure, in broken continua- 

 tion of the inner cell-streak, is a narrow bent streak, the upper por- 

 tion half crossing the medio-submedian interspace; the other portion 

 bent inward at right angles and sometimes sending a streak outward 

 to meet the mesial band; the duskiness of the base of the wing does 

 not extend over half the cell, and is enlivened by long olivaceo-ful- 

 vous hairs; some griseous scales border thinly and broadly the me- 

 dian nervure and its branches as far as the mesial band; the costal 

 border is fulvous, flecked on the basal half rather heavily with gris- 

 eous, edged with black, with the edge of the wing itself hoary. 

 Beyond the mesial band there are the following markings: two small 

 triangular spots with their bases resting on the subcostal nervure, 

 dividing the distance between the mesial band and the tip of the 

 wing; a row of six circular or subquadrangular spots, of equal size
