brown blotches. Xear 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

A. oreasella* Labial palpi silvery-white. Head silvery- 

 white ; forehead and face faintly tinged with pale golden- 

 brown. Antennas silvery, annulated 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
