sharply bent over the reniform, then rather evenly oblique to the sub- 

 median vein where there is another sharp outward tooth. Median shade 

 feebly marked 01 the costa only and lost in the dusky shading between the 

 ordinary spots S. t. line narrow, pale, irregular, defined by a dark 

 shading on both sides, which merges into the ground color in each 

 direction : this shading is most obvious opposite the anal angle. A 

 broken dark terminal line. The fringes have also a dark interline and 

 are cut with dusky and pale. Claviform extending half way across the 

 median space, black margined. Orbicular large, gray, oblique, oval, 

 outlined by black scales and touching the t. a. line. Reniform large, 

 upright, indefined, powdery, touching the t. p. line above and below. 

 Secondaries smoky fuscous, with an indistinct discal lunule and a dusky 

 line at the base of the fringes which are paler and have an almost white 

 line at their base. Beneath gray, powdery, both wings with a discal 

 spot and a somewhat crenulate outer dusky line. 

 Expanse 1.20 inches =- 30 mm. 



Hab. Colorado, Bruce. 



A single male specimen in good condition has been in my 

 collection for some time. It is also an ally of lustralis ; smaller, 

 of the same general wing form, but with no trace of reddish or 

 brown. There are a number of other minor differences in 

 ornamentation, and the sexual pieces of the male are quite differ- 

 ent : the clasper in this case being formed of a broad thick 

 spatulate process.

Ground color a sordid fuscous gray, with more or less obvious whitish 

 powderings. Head with a white line between the eyes ; collar with a 

 white central band and white tips ; patagi^e with the disk gray and with a 

 smoky or blackish submarginal line. Primaries with all the markings 

 obvious, tending to become somewhat obscured. Basal line geminate, 

 black, reaching to the sub-median vein on which a black patch fills the 

 line : included space more or less white powdered. T. a. line geminate, 

 the inner line scarcely defined, the outer broken, black or blackish, 

 included space with paler powderings. In course it is upright and only 

 broken by a slight inward angle on the submedian vein. T. p. line 

 geminate, the outer portion narrow, smoky, not well defined ; the inner 

 darker, marked with black scales below the cell and sometimes black 

 marked throughout : the included space pale or whitish. As a whole the 

 line has a strong outcurve over the cell, and is a little incurved below. 



5. t. line narrow, white, sometimes a little broken, irregularly marked by 

 broken, smoky preceding shades, which fill the s. t. space on the costa. 

 It is modified into more or less sagitate marks between veins 2, 3, 4, 5 and 



6. The entire terminal space, except the apex, is a little darker, more 

 powdery, cut by the paler veins. There is a series of blackish terminal 

 lunules, and a yellow line at the base < f the fringes, which are brown and
