base than the last, two more spots, somewhat larger, 

 between the branches of the median vein, and traces of 

 a small one on the submcdian. 



Hind wings uniform in tint, with a faint ochraceous 

 repetition of the markings beneath. The outer margin 

 of both wings is narrowly edged with black, the fringes 

 sliglitlj paler than the upper surface. 



Under side dark brown, on the hind wings ap- 

 proaching to black, with some grayish scales towards 

 the outer border. The fore wings have the markings 

 of the upper surface repeated with greater distinctness 

 than above, and a large pale brown spot at the posterior 

 angle. 



Hind wings with a band formed of grayish-white 

 spots between the venules, starting at the costa at two- 

 thirds the distance from the base, nearly reaching the 

 outer margin in the space between the subcostal and 

 median veins, thence bent towards the inner margin at 

 a little less than a right angle, terminating at the sub- 

 median. 



Male. — This form scarcely differs from the female on 

 the upper surface, except that the spots are a little more 

 distinct and pale yellow, especially the row on the hind 

 wings. Stigma, or sex-mark, oblique, narrow, black, 

 broken, the upper part longer than the lower. 



Under side as in the female. Body black above, 

 with greenish hairs, below gray, with a few greenish 

 hairs on the thorax ; palpi yellowish white, gray at the 

 tip. 



Grass is the food-plant of this species. 

 It has been found in Connecticut, New York, Texas 

 and Colorado.
