nearly as Salehria, differing- only in that there is but one strong spine 

 at beginning of anal opening, and one very long twisted spine far 

 within ; the last segment of abdomen beneath has two large hair 

 tufts. Venation : fore wings 11 veins, 4 and 5 separate, 10 separate; 

 hind wings 8 veins, 2 near angle ; 3 separate, 4 and 5 stemmed, 6 

 and 7 stemmed. 



1. S. lithosella Ea?., Dia^. N. A. Pbyc. p. 9, 1887.— Expands 32 mm. Fore 

 wings narrow, elongate, pale yellowish ochreous, costa indistinctly paler. A 

 brown spot on the dorsal vein indicates the iirst line, between which and the 

 anal angle the inner margin is dusted with brown. The lower discal spot and 

 marginal points minute, distinct.

A?VORII§»TIA Rag. 

 (Type umbrifascieUa Rag.) 

 Ann. Soc. Ento. France, 1887, p. 236. 



Labial palpi oblique, thick, squamose ; last member very short, 

 deflected; maxillary palpi invisible ; antennae of S pubescent, very 

 slightly bent and hardly crenulate above base ; fore wings 4 and 5 

 separate; hind wings 8 veins, 3 and 4 stemmed; appearance of 

 Epischnia. 



I do not know the type or the American species. The diagnosis 

 of Mr. Ragonot gives no characters that will properly separate this 

 from several other genera. The fore wings probably have 11 veins, 

 but this is not mentioned. Even if the genus be a good one it is un- 

 certain whether it is represented in this country, inasmuch as both spe- 

 cies described under it were described from females only, and till the 

 male is known no species can be more than jirovisionally located 

 save as there is some departure from the structure known to occur 

 in other genera in both sexes. 



1. A. flavidorsella' Rag., Diag. N. A. Phyc. p. 9, 1887.— Expands 1.5 mm. 

 Fore wings pale gray, finely and sparingly dusted with black; lines whitish 

 distinctly bordered in median area with fine black lines, the first oblique, sinu- 

 ous, preceded by a broad blackish baud, ill defined towards the base ; second line

 and marginal spots pretty distinct. Inner margin at base yellowish. Hind 

 wings yellowish white. Abdomen yellow.

2. A. olivella Hulst. — Expands 24 mm. Palpi whitish ; bead, thorax, ab- 

 domen and fore wings light fuscous gray, scatteringly and coarsely dusted with a 

 few black scales, the whole washed with a light olive shading; the black scales 

 are a little more plentiful at the base, along inner margin, and at apex ; basal
