This l^eauliful, delicate, little species differs lioni the oilier easferu 

 species in its wliitisli color and the l)road, sinuate, mesial, brown hand. It 

 closely resembles the Calii'ornian E. orridenlafa, and may Ijc lound to inler- 

 grade with it.

1 (?. — Fore wings with much the same shape as in E. aurora} ia of 

 Euro])e, though the a])ex is slightly more rounded, while the himl wings have 

 the outer ed<re more rotund. x\ntenna^ iinelv ciliated, l^odv and wiuiis 

 very pale tiiwn brown, tinged ver\- liiintly with vinous; vertex ol' head palo; 

 front and pal|)i dark l)rown. 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, taint, submarginal shade. On l)o1h wings, a row of venular, marginal, 

 black dots; friuije loiiir, silkv, concolorons with the wing. Hind wings with 

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

 rather more distinct; the broad baud 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 pah;, fore 

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

 smoky lines.

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

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

 ginal band much darker, while the liirm of the nuddle baud is (piite different.
