Tliis beautiful, delicate, little species differs from the other eastern 

 species in its whitish color and the broad, sinuate, mesial, brown band. It 

 closely resembles the Californian E. occidenfata, and may be found to inter- 

 grade with it,

1 $ . — Fore wings with much the same shape as in E. auroraria of 

 Europe, though the apex is slightly more rounded, while the hind wings have 

 the outer edge more rotund. Antennae finely ciliated. Body and wings 

 very pale fawn-brown, tinged very faintly with vinous; vertex of head pale; 

 front and palpi dark brown. Fore wings clear pale fawn, with the middle 

 occupied with a broad dark hour-glass-shaped band, wider on the front edge 

 than on the inner; the inner side quite regularly hollowed out, the outer side 

 produced outward in the middle, with two acute parallel teeth, and a third 

 below situated farther within the wing; below this, the band dilates on the 

 inner edge, while on the costal side it goes nearly straight to the costa ; a 

 diffuse, faint, submarginal shade. On both wings, a row of venular, marginal, 

 black dots ; fringe long, silky, concolorous with the wing. Hind wings with 

 the same markings as on the fore wings, but with the submarginal shade 

 rather more distinct ; the broad band has two larger teeth on the outer edge, 

 and the shade beyond has two zigzag angles parallel with it. Obscure yel- 

 lowish discal dots on both wings (distinct under a lens). Legs pale, fore 

 femora and tibiae dark. Beneath, smoky, the bands being replaced by diffuse 

 smoky lines. 



Length of body, 0.24 ; of fore wing, 0.33 ; expanse of wings, 0.66 inch.

This fine species differs from the eastern species {E. gemmata) to which 

 it is structurally closely allied, in having rather darker wings, with the submar- 

 ginal band much darker, while the form of the middle band is quite different.
