acutely bent on costa and even below. An obvious smoky median shade 

 is obl'que from costa over reniform and darkens the outer part of median 

 space. S. t. Hne pale, broken, very even, accompanied by a somewhat 

 rufous smoky shade. A series of small terminal lunules. Fringes a little 

 rufous. No claviform. Orbicular concolorous, round when visible, 

 indicated by orange scales, Reniform darkened by median shade, and 

 more or less edged with orange scales. Secondaries in the male gray ; 

 in the female smoky-yellowish, in all with a discal lunule. Beneath, 

 primaries gray, with an incomplete smoky outer band. Secondaries 

 whitish, powdery, with a round discal spot and an incomplete punctiform 

 outer band. 



Expands: i. 35-1. 60 inches = 34-40 mm. 



Habitat. — Arrowhead Lake, British Columbia, June 8-15; Beulah,

One male and two females in good condition in Dr. Barnes's and my 

 own collection. The species is allied to Quebecensis, and like that 

 resembles a Cariieades ( Euxoa) of the Bosionie?isis type. It differs from 

 the eastern species in the less obvious maculation and in the outward 

 rufous shadings. There is quite a bit of variation indicated since the 

 male has nothing except the reniform and median band that is at all 

 obvious. 



Euxoa esia, n. sp. — Head, thorax and primaries smoky black, with 

 minute yellow powderings. Collar with a deeper velvety-black median 

 line, dorsal tuftings of thorax and edges of patagia with some white scales. 

 Primaries with all the maculation obscured, yet most of it traceable on 

 good specimens. Usually the median lines are traceable by yellow atoms 

 more or less black-edged each side, the t. p. being most obvious. S. t. 

 line punctiform, also marked by yellow atoms and velvety-black defining 

 scales. There is a very narrow pale line at base of fringes. At base is a 

 black longitudinal mark. Claviform narrow, black-margined, sometimes 

 with yellow atoms, extends not quite to centre of median space. Orbicular 

 moderate in size, round or oval, concolorous, ringed by black and yellow 

 scales. Reniform kidney-shaped, moderate in size, with a ring of yellow 

 scales margined by black. Secondaries in male yellowish-white at base, 

 becoming smoky outwardly ; in female smoky throughout, but paler 

 basally ; the tendency is to a smoky discal spot. Beneath, primaries 

 whitish to extra median line, smoky and powdery beyond ; secondaries
