Ground color a rich dark brown, varying to smoky. Head and thorax 

 concolorous. Abdomen fuscous; the edges of the segments feebly pale 

 ringed. Primaries quite even in color, the prominent white lines reliev- 

 ing the uniformity. Transverse anterior line even, slender, white, with 

 two outward angulations. A white line from base to the transverse 

 anterior hue at its middle, below which the basal space is white pow- 

 dered. In the male this is all obscure, and sometimes quite lost. Trans- 

 verse ])OSterior line double, white, the intervening s})ace quite broad 

 and of the ground color, in course a little irregular, but with a great 

 central outcurve or bulging, much widening the median space. Sub- 

 terminal line white, inwardl}' oblique until it reaches near the trans- 

 verse posterior line, with which it runs rather closely parallel for the 

 remainder of its course and with the outer line of which it is connected 

 by white lines on the veins, cutting the subterminal space into brown 

 spots, the largest of which are on the costa and internal margins. 

 Apex pale, often white, interiorly nnirked by a more or less evident 

 brown or black oblique shade, below which the terminal space is often 

 more or less white, gray, or bluish marked. A series of brown terminal 

 lunules, beyond which is a pale line at the base of the fringes, which 

 latter are cut with yellowish. Ordinary spots black, small, marked by 

 raised scales, as usual. Secondaries uniformly fuscous or smoky, with 

 a darker terminal line. Fringes with a yellow line at base, a blackish 

 interline, and whitish tii)ped. Beneath reddish-gray, powdery, with a 

 common outer line within which the primaries are darker; secondaries 

 with a discal lunule. 



Expanse of wings, 25 to 32 mm.=l to 1.30 inches,

This is an easily recognized species. The contrasting narrow white 

 line, the transverse posterior so strongly curved, and the cutting of 

 the subterminal si)a(;e are characteristic of the species. The male is 

 much the larger and more robust, the difference in all respects quite as 

 marked as m 7>. scuteUarls; but there is less difference in the ornamen- 

 tation. While the male is darker and more sordid as a whole, the white 

 rather dirty, yet there is no greater difference or lack of contrast. The 

 wing form is most like that of B. matialis, the female rather broader 

 and more obtuse, the male with somewhat more pointed ajHces and 

 more oblique outer margin of primaries. The species is not a rare one 

 and is even locally common.
