Or. strigifinitella . Labial palpi yellowish white, dotted with dark 

 brown, and with two dark brown rings before the tip. Head and antennae 

 dull yellow. Fore wings brownish gray suffused with dark brown, with the 

 inner margin, from near the base to the middle, varied with white and dark 

 brown ; on the middle of costa a white streak, and a few small, costal, dark 

 brown blotches. Near the tip, on the inner margin, a slender, very oblique 

 white streak, dark margined on both sides, which crosses an oblique streak of 

 the same hue from the costa, likewise dark-margined on both sides above the 

 streak from the inner margin, and curved beneath, forming a white hinder- 

 marginal line in the cilia, beneath the tip, and extending nearly to the apex 

 of the wing. Beyond these, toward the base, in the apical third of the wing, 

 are two oblique, dark brown costal streaks, with a short, white one between 

 them, the first irregular and somewhat diffused, the second margined behind 

 with brownish yellow. Apical portion of the wing dark brown. Hind wings 

 dark brown ; cilia somewhat paler. 



G violacella. Head and face pale yellowish, tinged with reddish 

 violet. Labial palpi yellowish white, annulated at the tip with brownish. 

 Fore wings with the external half pale, shining, cream yellow, interior half 

 suffused with a pale violet iridescence. About the middle of the costa are a 

 few separated blackish brown dots, and in the middle of the wing a blackish 

 brown comma spot, and near the tip an atom of the same hue. The posterior 

 part of the fold somewhat suffused with fuscous ; cilia reddish fuscous. Hind 

 wings dark gray, with a reddish tinge ; cilia reddish fuscous. 



Argyresthia Hubner. 



A. or ease 11a. Labial palpi silvery white. Head silvery white; fore- 

 head and face faintly tinged with pale golden brown. Antennae silvery, annu- 

 lated with dark brown. Fore wings silvery white, with a pale golden brown 

 streak at the base of the costa. About the middle of the wing is an oblique, 

 dark golden brown band, broadest on the inner margin, and tapering to the 

 costa, beyond which is a narrower, oblique band of the same hue produced in 

 the middle, as a rather broad, somewhat curved streak toward the tip, behind 

 which it is arrested ; cilia pale golden brown, with a darker hinder-marginal 

 line ; hind wings dark gray ; cilia the same. 



Another specimen, on the middle of the inner margin, has a rectangular, 

 golden brown patch, not extended to the costa, with an irregular, obliquely 

 placed patch of the same hue on the inner margin, near the tip, and slightly 

 connected with a small costal patch placed midway between the patches, on 

 the inner margin. The tip of the wing is golden brown, and is scarcely con- 

 nected With the second patch by a posteriorly produced portion. 



Taken on wing, June, July. 



Ornix Zeller. 



0. trepidella . Labial palpi yellowish white, annulated with dark brown 

 near the tip. Head dark brown. Antennae dark brown, slightly annulated 

 with whitish. Fore wings dark purplish, dusted with dark brown. Along the 

 costa are several short, oblique, obscure yellowish streaks, with dark brown 

 streaks between, extending from the middle of the wing to the tip, obliquely 

 placed till near the apex. Hind wings dark gray ; cilia the same. 



0. festinella. Labial palpi silvery gray, with the second joint at the 

 apex annulated with dark brownish. Head dull brownish gray. Antenna? 

 dark brown, annulated with whitish. Fore wings grayish, somewhat suffused 

 with brownish from the base to the middle, with the costa at base dark 

 brown. From the middle to the tip freely dusted with dark brown, with 

 several whitish, rather obscure costal streaks, becoming plainer near the tip, 

 and two or three on the inner margin, near the tip. At the tip are a few dark
