brown specimens most prominently so. Basal line wanting; at all 

 events not traceable. T. a. line usually obsolete, in one well marked 

 brown specimen traceable as a pale, outwardly oblique line, without 

 definite margins, and angulate in the interspaces. T. p. line geminate, 

 rather even, pale, outcurved over the cell and slightly incurved inte- 

 riorly ; inner part of line usually distinct, outer part not well defined ; 

 ill some specimens the line is not traceable below the costa. S. t. space 

 darker costally, a distinct dark shade aud a series of sagittate blackish 

 spots preceding the narrow, pale, and slightly irregular s. t. line; ter- 

 minal space darker than ground color. In a brown specimen with well 

 marked t. p. line the s. t. is decidedly paler than the median space, and 

 this is the case to a variable extent where the t. p. line is marked. A 

 black basal dash, interrupted by the t. a. line, the small loop-like clav- 

 iform continuing the dash beyond the line; this spot is very variably 

 distinct, but usually not completely outlined. Cell around the ordinary 

 spots dusky to black. Orbicular variable in shape, always open supe- 

 riorly. V-shaped to oblong, oblique, the change being made by cutting 

 the outer horn of the V ; iu color like the costal region, sometimes with 

 a darker center. Reniform moderate in size, kidney-shaped, white 

 ringed, the center concolorous with costa or somewhat darker. Sec- 

 ondaries smoky fuscous, with a variably evident discal lunule. Beneath 

 powdery with a very variable distinct outer line aud a more uniformly 

 defined discal spot to all wings. 



Expands 35-38"'™ ; 1.38-1.50 inches. 



Habitat. — California (Neumoegen). 



Three very strongly dissimilar specimens, all females. The species 

 is most nearly allied to idahocnsis, dift'ering principally in the very dis- 

 tinct shade containing still darker sagittate spots preceding the s. t. 

 line, which is less dentate than in its ally. The variations have been 

 indicated in the description.

Smoky fuscous brown; the costa broadly gray. All the lines obso- 

 lete. A basal black line; cell blackish ; claviform marked. Ordinary 

 spots concolorous, gray powdered. Orbicular round, open above; ren- 

 iform not distinctly outlined. Secondaries fuscous ; a dusky lunule 

 evident. Beneath dusky, powdery; a distinct dark discal lunule. 

 Head and thorax concolorousj collar inferiorly gray, marked with a 

 black line. 



Expands 32""" ; 1.30 inches. 



Habitat. — Labrador, Greenland. 



Allied to idahoensis, but at once distinct, not only by the obvious 

 differences in maculation, but also by the shai)e of primaries, which in 

 this species have the costa very strongly convex, whereas in the former
