2 i and 2 9 . — The wings of this s]iecies are more aiignlar and tiie hind 

 wings more dentate than in E. duaria, but less so than in E. hypochrnrin. On 

 the hind wings, the sinus is deep hut simple, not iiaving tin^ small tooth pres- 

 ent in lijijioclirariii. The general color is whitish-ash, much lighter than in 

 the allied species. Head and antcnnte reddish. Wings whitish-ash, with 

 reddish-brown scales on the costa near the head. Fore wings with two dark- 

 brown lin(>s, the inner ])ent and curved as in lit/jiochrar'ta, while the outer line 

 is straight in the male, not sinuous, being still straighter than in pilosaria. 

 In the i'eniale, the line is flexuous on both wings. Accompanying and beyond 

 the line is a broken, broad, difTuse band, often obsolete, in one male entirely 

 so. An ol)S()lete, dark, apical line (absent in one male). Distinct black 

 discal dots on both wings. Ilind wings \vith a single dark line, fading out 

 toward thi; discal t\u\. Beneath, the common line is more conspicuous than 

 above, washed with orange, as is the under side of the wings generally, while 

 just beyond the line on the outer third of the wing is a leaden |)atcii. Th(! 

 discal dots are smaller than aliove.

This species need not be confounded with any other, as the outer line 

 common to both wings is straight in the male and slightly sinuous in the 

 iinnale, much less so than in E. duaria. It is also whitish-ash, and washed 

 with orange l)eneath more than in the otiier species.
