to within internal angle ; outside of this the wing is paler. 

 Hind wings dark fuscous. Head and thorax dark brown. A 

 male, received from Mrs. Fernald, taken at Orono, Maine. Pre- 

 viously I only had the female. The species is nearly concolorous, 

 and may be known by the curved s, t. line. 



AZENIA. n. gen. 



Vestiture flattened hairy. Eyes naked. Form very slender, 

 like Sp7'agueia, wings narrow, long, primaries widening a little 

 outwardly. Antennae simple. Legs unarmed, thinly scaled. 

 Front with infra-clypeal plate prominent, but overshadowed by 

 a parallel, long, distinctly tridentate, flattened, clypeal protuber- 

 ance. Labial palpi closely scaled, a little longer than in Xan- 

 thoptera. 



AzENiA Implora. n. s. 



Pale lemon yellow. Two ochrey dots in place of t. a. line. 

 A median ochrey shade band, irregular and faint. One or two 

 dots in place of t. p. line. Minute points at base of pale fringes. 

 Hind wings white. Beneath whitish ; costa of fore wings a little 

 clouded. Head and thorax like fore wings. Abdomen pale, a 

 little exceeding secondaries. Arizona, coll. B. Neumoegen, Esq. 

 The armature of the head is disproportionately large. 



Xanthoptera Clausula, n. s. 



Allied to Scniiflara, but much smaller. Thorax and base of 

 primaries bright lemon yellow. A fine white line, perfectly 

 straight, divides the yellow base from the leaden outer field which 

 is delicately frosted with white, and encloses a vague white cloud- 

 like spot, the reniform. Fringes interrupted with pale yellowish 

 above internal angle, outwardly. Hind wings translucent fuscous. 

 Abdomen pale. Beneath pale, glistening, with reflected darker 

 shades on fore wings. Arizona, Coll. B. Neumoegen Esq. 



The labialpalpi are short ; front globose. Eyes large and 

 naked. Agrees with Semiflava, which I have left with the type 

 of the genus Ni^ro fimbria, in XantJwptcra. 



ESCARIA. n, gen. 



Wings frail, wide, abdomen untufted, a little longer than 

 hind wings, body slender. Labial papi short. Eyes naked, un- 

 lashed. Front with a moderately prominent, rather wide, cup- 

 shaped protuberance, nearly hidden by the erect vestiture and 

 with a central protuberance, not reaching over edges of cup, set 

 in erect vestiture which fills the cup itself. Vestiture mixed, flat- 

 tened hair and scales. Legs apparently unarmed. Seems to fall 

 in between the Tarac]ie-X\\.& genera and Eustrotia. Size of E. 

 Carneola. 



EscARiA Clauda. n. s. 



Grayish fuscous. In the $ the ornamentation is better 

 written. Orbicular paler, spherical. Claviform moderate, its 

 upper edge accentuated in black. Reniform moderate, lunate. 

 Lines fine, perpendicular, edged with pale or whitish, especially
