some specimens the cell is considerably darkened, in others very slightly 

 so. The secondaries are whitish, dusky along margins in male, in the 

 female dusky throughout, though somewhat lighter at base. Fringe dusky 

 at base, white externally. Beneath//j////a is much darker and has a well- 

 marked mesial line on both wings, of which there is no trace in the 

 Colorado form. 



As a whole they are quite different looking insects, aside from the 

 difference in markings, and, if I am correct in the identification of 



Harvey's species, there can be no doubt but that the Colorado ones are 

 new.

General type of maculation recalling convexipennis, ground colour a 

 rather clear bluish gray, with a faint reddish-brown flush, markings in 

 brown varying in shade from light reddish through dark umber to almost 

 black. Transverse lines almost obsolete. Extreme base of wing dark 

 umber brown, with a small white spot next to costa. Inner margin with 

 narrow dark brown, almost black, line. A prominent dash above inner 

 angle of same colour, interrupted at its inner fourth by a pale lunule. A 

 small blackish spot below costa, just before orbicular, and a larger, more 

 diffuse one between reniform and orbicular from costa to median vein. 

 The latter is continued as a faint shade obliquely to inner angle. The 

 wing between this band and base is a rather clear gray, only very faintly 

 tinged with reddish brown ; beyond the band and above the median vein 

 the wing is a light brown, slightly darker outwardly and above, the costa 

 being, however, narrowly gray, with two or three pale dots and one or two 

 outwardly oblique short black dashes. Beyond the band below median 

 vein the wing is gray but considerably washed with brown, especially out- 

 wardly. The veins, especially the median and its branches, are darkened. 

 Orbicular small round, brown, with faint interrupted blackish limiting line. 

 Reniform moderate in size, upright, kidney-shaped, limiting line dark 

 umber brown, outwardly more blackish, inwardly fragmentary. The spot 

 is not conspicuous, being concolorous with the brown subapical shade 

 which embraces it. The t. a. line is almost obsolete, but on very close 

 inspection it can be made out. It makes a wide, outwardly projecting
