AMERICAN LEPIDOPTERA. 59 



the apex. A broken black terminal line. Fringes mostly gray, a whitish patch 

 at about middle and another half way between it and apex. Orbicular puncti- 

 form, small, often wanting. Eenifurm obscure, at its best upright, oval, the sides 

 outlined by black or olivaceous scales. On some examples it is barely indicated. 

 Secondaries smoky yellowish, very light and a little glistening. Beneath, prima- 

 ries yellowish, disc smoky ; secondaries white, smoky toward outer margin. 

 Expands 23-27 mm. = .92-1.08 inches. 



Hab. — Kot Springs, New Mexico, 7000 ft. (Hulst) ; Colorado 

 (Bruce); Black Hills, Montana (Hulst). 



Seven examples, five of them nmles, are before me. They vary 

 in the amount of dark shading, but in no case is the yellowish cos- 

 tal shade cut before the inception of the t. p. line and then incom- 

 pletely. As it happens, both specimens where this occurs are 

 females, and it may be that in this sex there is uniformly more 

 gray. Four of the males hav^e the creamy margin unbroken to the 

 s. t. space. 



Vein 5 is as strong as the others and from the median at the end 

 of the cell. Veins 3 and 4 branch one-third from the end of the cell.

 Head and collar white or with a faint yellowish tinge, more or less gray mot- 

 tled. Thorax else smoky gray or brownish. Abdomen yellowish, pale gray. Pri- 

 maries white or faintly yellow tinged along the costal margin, the costa itself gray 

 shaded. The white shade extends from base above the median vein to the med- 

 ian shade. It is there interrupted in whole or in part, and beyond this the white 

 is reduced to half its width and again interrupted at t. p. line, leaving an irregu- 

 lar though subqnadrate spot in the s. t. space. The dark shading of the wing is 

 smoky gray, sometimes with an olivaceous tinge, extends through the lower part 

 of the wing from base to s. t. line and through s. t. space to the apex. S. t. space 

 bluish or white mottled inferiorly, varying in amount. Terminal space white 

 mottled, except at apex where it is gray, emphasized by a small black spot. T. 

 a. line traceable in most specimens through the dark portion of the wing, single, 

 upright. Median shade olivaceous on costa where it starts as a triangular patch, 

 wholly or almost crossing the pale costal space, usually lost in the darker shade. 

 T. p. line starts from an olivaceous quadrate costal patch varying in size, fragmen- 

 tary over the cell, deeply incurved below and made up of blackish, lunate, inter- 

 spaceal marks through the dark shading. S. t. line white on the costa, broken 

 and irregular at apical fourth, then diffuse and more or less filling the terminal 

 space. A black terminal line, broken on the veins. Fringes long, gray at base, 

 violaceous outwardly, cut with white at apical fourth. Orbicular wanting, or a 

 small black dot only. Eeniform round or nearly so, olivaceous ringed, sometimes 

 olivaceous filled as well. Secondaries grayish to smoky, with white fringes. 

 Beneath faintly yellow tinged, primaries with disc irregularly smoky; second- 

 aries with a small discal lunule and a narrow, smoky outer border. 

 Expands 25-28 mm. = 1.00-1.12 inches.
