Palpi, whitisli, with a slender line of brown scales extending along the outer side ot 

 the apical joint. 



Head, brown, with central and lateral slender white lines running back over the 

 thorax, which is also brown; face whitish. 



Fore-ivings, brown, with two short rather broad silvery dashes at about one-fourth 

 from the base, the first nearest the costa, commencing also nearest to the base ; a 

 very slender silvery line from the base along the dorsal margin ; and a short ob- 

 lique streak of the same color teudingdowu wards from the costal margin towards 

 the apex of the upper dash ; beyond the basal half of the wing is the usual orange- 

 yellow space, limited internally and externally by shining steel-gray metallic 

 spots, the pair adjacent to the costa being much wider ajiart than the opposite pair, 

 which are adjacent to the dorsal margin; there is a white streak in the costal 

 cilia touching the upper and outer metallic spot, and a similar apical streak is 

 continued a very short distance along the dorsal margin ; cilia steel-gray, with a 

 slight greenish tinge. 



Hind-wings and cilia, the same color. 



Legs, brownish ; tarsal joints smeared and spotted with Avhite.

Cosmopteryx qiiadrilineella Chamb. 



I have a single specimen from Sonoma County, Cal., taken iu May, 1871, which 

 agrees iu size and pretty closely in markings with this si)ecies, to which I am in- 

 clined to think it belongs, Although the specimen is in somewhat i)oor condition it 

 can be easily recognized as distinct from delicatella. 



Cosniopter5'x delicatella sp. n. 



Palpi, silvery, with some brownish scales towards the base. 



Head, brown. 



Antenna', brown, the apex broadly white with two narrow white rings separated from 

 the apex by a still broader brown band. 



Thorax, brown, with three narrow silvery white streaks, one central, extending from 

 the head along the thorax. 



Fore-icings, brown, the basal portion with four narrow silvery-white lines ; the first 

 from the base of the costa tending somewhat downwards ; the second commenc- 

 ing o^iposite to the middle of the first and extending somewhat beyond it; 

 the third commencing beyond the origin of the second and extending very 

 slightly beyond it ; the fourth immediately above the dorsal margin, commencing 

 near the base and extending to the origin of the third ; about the middle of the 

 wing is a broad pale-orange band, on the basal edge of which are two golden 

 spots, the upper oue opposite the end of the second basal streak, tipoed with 

 blackish scales ; the second farther from the base, larger and- more conspicuous 

 than the first, situated opposite to the end of the third basal streak ; at the outer 

 edge of the pale-orange band are two similar spots separated by a narrow exten- 

 sion outwards of the orange color, the first situated immediately above the other, 

 but not touching the margins of the wing ; a small white streak extends out- 

 wards along the cost.a from the upper spot, and from the narrow extension of the 

 orange band there runs a slender silvery- white line, somewhat ai'(died upwards and 

 terminating in the extreme apex of the cilia; the space above and below it, in- 

 cluding the cilia themselves, being of the same brown color as the base of the 

 wing. 



Uindivings and fringes, also brown. 



Abdomen, brown, aual segments tending to ochreous.
