palpi and inferior portion of front often light brown; antennae yel- 

 lowish or light brown with a white spot at the base of each, which 

 are rarely connected l>v a faint, broken line across the front. Ground 

 color of wings soft granite-gray, more or less speckled over with 

 dark-brown atoms which occasionally form short strigations on the 

 costa and in the outer area of primaries. Inner line of primaries 

 conspicuous, sometimes broad and diffuse, scalloped, the first sweep 

 from costa less oblique on the whole than in the other species. Outer 

 line distinct, ratherly evenly sinuous, usually not producing angles 

 al the veins. Median area fawn-brown, rarely (\cvu brown, con- 

 trasting strongly with the granite-gray inner and outer area. Discal 

 spot white, angular, linear, quite large, and conspicuous. Second- 

 aries divided subcent rally by a denticulate or wavy line, the greatest 

 angle or wave on the first anal vein. A small brownish discal spot 

 sometimes showing. Three or four black lunules are on the outer mar- 

 gin near the anal angle. Beneath, smoky-gray ^ washed over with 

 pale brownish on costal and outer areas, and with a patch of dark 

 brown strigations on inner area of secondaries. Cross lines occa- 

 sionally visible. Discal spot of fore wings as above, but smaller 

 and margined on one side with black: of secondaries quite large, con- 

 spicuous, and composed of closely set atoms which rarely disperse, 

 leaving a dusky spot. 



Habitat "California" (Packard); Sierra Nevada. California, Ore- 

 gon (Am. Mus. Xat. Hist.); Oregon (AY. S. Wright); Portland, Oregon, 

 June (J. A. G.); Kossland, British Columbia. June 3 (U.S.N.M.). 



A very distinct and easily recognized species, separable from all 

 others by the granite-gray ground and the sharply defined brown 

 median area. The male genitalia are nearest to lionestarius but are 

 more triangular in form. 



Judging from the specimens in hand Oregon is the true home of 

 the species, since seven of the nine examples come from that State 

 through three different sources. The other two localities, however, 

 bespeak a range extending from lower British Columbia to central 

 California. It is probable that the species is alpine, occurring on the 

 Cascade and Sierra Nevada mountains.
