ami below two dusky lines extend lo the inner edge of wing, the inner being 

 the wider. The discal dol is curvilinear, black, very distinct, edged with 

 while externally, and raised, forming a high crest. A few red scales are scat- 

 tered over the space inside the discal dot. Beyond the discal dot is a broad, 

 clear, pale-gray band, with a row of longitudinal, black, linear spots on the 

 outer edge, becoming longer Inward the costal edge of the wing. This broad 

 space terminates on the subcostal vein; il is limited on the outer edge by a 

 wavy, lighl line. Beyond is a row of reddish, diffuse patches, forming a wide 

 series of scallops. The outer edge of the wing is dusky-gray ; along the base 

 of the fringe is a linear, narrow, black line, interrupted by the ends of the 

 venules. The long fringe is dirty-white, witli slightly darker scales. Hind 

 wings clear on the costal and median areas, with a distinct, round, discal dot; 

 the inner and submedian region covered with dark and light alternating, 

 crinkled lines, most marked on the venules. Beneath, fore wings clear, with 

 costa dusky at base; discal dot distinct, linear, extending nearly to the costa. 

 Half-way between it and a subapical black patcji is a black line consisting of 

 two dots. Beyond the discal dot both wings are lineated finely with black 

 and gray, and the black line at base of fringe is very distinct. 



Length of body, 0.40; fore wing, 0.50; expanse of wings, 1.05 inches.

This beautiful form may be recognized by the whitish-ash wings, with 

 russet-brown mixed with dark-ash bands and patches, and the russet-brown 

 costo-apical patches*. It is closely allied structurally to E. ravocostaUata.

16 $ and 9. — The fore wings are lanceolate-oval; the outer edge of the 

 wing being very long and oblique, and as long as the inner edge of the wing. 

 It is russet-brown, the vertex being considerably paler than the front of the 

 head and palpi. The male antennae are finely ciliated beneath. Fore wings 

 russet-brown, with dark scales along the veins and their branches. No distinct 

 markings or transverse stripes except a pale, whitish, slightly zigzag, marginal 

 line, most distinct near the inner edge of the wing, and near the apex touching 

 on the outer end of a large, conspicuous, oblique, ochreous-white patch. The 

 discal dot is large, round, black, distinct. Along the costa are faint-brown 

 spots, especially above the discal dot, where four of them are slightly marked.
