 annulated with brown. Fore wings uniform, bronzy green, with the apical 

 portion reddish violet, or of a reddish, coppery hue. Hind wings dark brown ; 

 cilia the same. 



Stalk somewhat thickened, with scales not erected. 



C. laticornella . Labial palpi and head brownish ochreous. Antenna? 

 pale brownish ochreous towards the base, becoming white with an ochreous 

 tinge toward the tip, and annulated with dark brown throughout. Fore wings 

 rather deep, uniform brown, with a whitish ochreous streak along the costa, 

 from the base to the costo-apical cilia, narrowing behind, and not reaching 

 beyond the subcostal nervure. Hind wings rather dark brown ; cilia the same. 



Antennal italic simp J e; basal jo'nt thickened with scales. 



C. coenosipennella . Labial palpi and head white. Antennae white, 

 annulated with dark brown ; basal joint white. Fore wings dull yellow, with 

 a white streak along the basal portion of inner margin, one along the costa, 

 and one along the subcostal nervure, separated from the former by a narrow 

 line of the general hue ; an oblique, white streak along the disk, and inclined 

 to the inner angle, and one in the fold, with three rather faint, oblicpze, white 

 streaks between the terminal portions of the costal and discal streaks. Hind 

 wings rather dark gray ; cilia fulvous. 



C. infuscatella . Labial palpi brownish gray. Head pale leaden gray, 

 whitish on the sides and above the eyes. Antennae gray, annulated with dark 

 brown. Fore wings grayish brown, with a white streak along the costa to the 

 tip, and one along the inner margin ; a white streak along the fold, and one 

 parallel to it along the middle of the wing, and somewhat dilated on the inner 

 margin ; cilia grayish brown. Hind wings gray ; cilia the same. 



C. c r et at ieo s tella . Labial palpi white. Head white, tinged with 

 yellowish. Antennas white, annulated with brownish. Fore wings shining 

 yellow, with rather a broad white streak along the costa, extended nearly to 

 the tip ; somewhat streaked with ochreous, and the tip rather deep ochreous. The 

 inner margin of the wing is whitish. Hind wings ochreous brown ; cilia the 

 same. 



Incuevakia Haworth. 



I. russatella . Head ochreous. Antenna? dark brown, ochreous at the 

 base, and annulated with ochreous. Thorax purplish brown. Fore wings 

 deep fuscous, with a beautiful purple reflection. Near the base of the wing 

 is a very pale yellow band, broadest on the inner margin, and a costal and 

 dorsal spot of the same hue opposite each other, a little beyond the middle of 

 the wing. Hind wings pale fuscous tinged with purplish red ; cilia pale brown. 



The wing structure of the following species departs from that of the genus. 

 Both wings are pointed, the fore wings with a single discal nervure, given off 

 to the inner margin and the hind wings with two discal nervules branching 

 from a common stalk. 



I. Acerif oliella. Ornix Acerifoliella Fitch, Reports, 1 and 2, p. 269. 

 Head reddish ochreous. General hue a fine metallic green ; fore wings without 

 markings. I am indebted to the kindness of Dr. Fitch for a specimen of this 

 insect.
