anterior line is geminate, brown, a little outcurved from the costa to 

 the siibmedian interspace, where it becomes lost in the dark shading of 

 the wing. The median shade is marked on the costa and extends out- 

 ward sufficiently to darken the space between the ordinary spots. Tlie 

 transverse posterior line is distinct, squarely outcurved over tlie cell, 

 and with a deep inward curve in tlie submedian interspace. It is gemi- 

 nate, the outer line lunulate and black, but fine, the inner lino brown, 

 slender, frecpiently defined only by the fact that the included space is 

 paler. The space beyond the transverse i)osterior line is a little, brown 

 shaded, and the terminal space is more evenly dark, relieving a diffuse, 

 whitish, irregular subterminal line. There is a slender black terminal 

 line and a series of small terminal dots, beyond which the interlined 

 fringes are cut with blackish. There is a black basal streak which 

 extends to the transverse anterior line and below this the wing is 

 shaded with blackish brown or smoky. Beyond the transverse ante- 

 rior line this shade extends nearly to the transverse i)osterior line, 

 being best marked on each side of the internal vein, where there is a 

 black streak extending nearly across the median space. An arrow- 

 shaped mark extends from the outer margin, just above the anal angle, 

 inwardly to the transverse posterior line, which it barely crosses. Tlie 

 ordinary spots are fairly evident but not prominent, a little lighter 

 than the ground color, very narrowly ringed. The orbicularis almost 

 ronnd and varies in size. The reniform is kidney-shaped and has a 

 slightly yellowish shade, which is also somewhat marked at the base of 

 the wing. In some specimens the shading just outside of the trans- 

 verse posterior line is brownish. Secondaries pure white in the male, 

 with a smoky line at the base of the fringes; in the female the outer 

 margin is a.Iittle dusky. Wings beneath white, very slightly powdery, 

 with hardly tra(;eable outer lines and discal dots. 



Expanse, l.'-'O to 1.40 inches (30 to 35 mm.). 



Habitat. — Los Angeles, Nevada County, and Sierra Nevada, Cali- 

 fornia; eastern Washington; Garfield County, Colorado, 7,()()() feet 

 (IJruce); Glenwood Springs, Colorado, May and September (liariies). 



I have seen 10 specimens of this species, evenly divided as to sex, 

 and very little difference indeed between them. The species is very 

 easily distinguished by the dark shading along the internal margin, 

 resend)ling in this particular /uwenf^/.s-, but differing from it in the more 

 arched costa, the less curved outer margin, and in the fact that the 

 black shading does not send up spurs along the interior ])art of the 

 transverse anterior line. There is very little variation in the species so 

 far as it is represented in the series before me. The size ol' the orbicu- 

 lar varies somewhat; there is a little change in the depth of the ground 

 color, and in some specimens a dull ochery tinge is evident. The head 

 seems small, the front flat, the palpi well developed and reaching to the 

 middle of the front. The harpesof the n)ale are oblong, a little curved, 

 evenly rounded at the tip. The clasi)er is well developed, beak-like at
