way to the hinder luargiu, entirely filling the disco-central interspace within 

 one-third of the marfjin, the middle portion of the medio-superior, the base of 

 the central and posterior interspaces; the outer margin of this shade is doubly 

 curved, convex toward the hinder margin, becoming concave from the medio- 

 superior uervule; the inner margin of the wing beneath the submedian nervure 

 is brownish from the base to the middle; tlie tips of the nervules are touched 

 with umber brown ; cilia umber brown, spotted with white on the interspaces ; 

 posterior wings above and beneath ochreous gray, lighter at the base. Expands

 middle, with a short white line on the upper edge of the patagise ; anterior wings 

 broader than in the male and longer than the body ; color umber brown, with a 

 darker brown costo-bas-al spot, another on the internal margin near the base, 

 which is continued in a dark shade along the internal margin: a similar colored 

 spot occupies most of the apical interspace and there are two within the post- 

 apical ; within the cell a subquadrangular blackish brown spot; of the umber 

 brown shade, which in the male rests on the nervules, scarcely more than its 

 hinder margin is visible, and that indistinctly ; middle of the wing at base dusted 

 with grayish scales and the nervules are also more or less dusted with grayish, es- 

 pecially the branches of the subcostal vein. Posterior wings above darker upon 

 the apex and upon the hind margin than in the male, and beneath without the 

 ob-scure band which crosses the middle of the nervules in E. harrisii. Cilia 

 white, spotted with dark umber on the ends of the nervules. Expands 2.10

Ditters from harrisii in the darker col.tr, the absence of the gray 

 shades and the much less distinct markings. The insect is extremely 

 rare. 



Mr. Lintner has also described the larva, which resembles quite 

 closely that of E. harrisii.
