Thorax, brovrnisb-fuscous, witb a faint iiurplisb tinge, posteriorly fringed •with 

 wbitisb-ocbreous. 



Fore-icings, remarkably narrow in proportion to their length for this genus, whitish- 

 ochreous; a basal patch, wider on the costal than on the dorsal margin, of a 

 brownish-fuscous color, is followed by a small triangular ^latch of the same color 

 immediately before the middle of the wing, and this is scarcely separated by a 

 short space on the costa, from a larger patch of the same form immediately beyond 

 the middle ; the lower points of these two triangular patches are directed ob- 

 liquely outwards, at the same angle as that followed by the dorsal extension of 

 the basal patch; the apical portion of the wing is entirely whitish-ochreous with 

 a few scattered brownish scales about the base of the cilia ; cilia whitish-ochreous. 



Hind-wwgs, shining, whitish ; cilia whitish-ochreous. 



Abdomen, shining, pale grayish-ochreous.

Qjcophora dimidiella sp. n. 



Antennae, brown, faintly barred with whitish. 



Palpi, dark brown ; apical joint tinged with yellowish towards the apex. 



Tongue, brown, clothed with brown scales on the basal half; apical half naked, yel- 

 lowish. 



Head, shining, yellowish. 



Thorax, deep brown. 



Fore-icings, deep brown, with several paler patches; the 1st and most conspicuous lies 

 partly above and partly below the fold, reaching to the dorsal margin at about 

 the basal third of the wing ; this is shining pale yellowish (silvery-white wher- 

 ever the scales have been abraded) ; on the middle of the costal margin is a 

 smaller silvery-white spot followed by a similar spot at the commencement of 

 the costal cilia; the lower end of the outer spot is bright yellow, it terminates 

 somewhat obliquely before reaching the middle of the wing, its ai)ex being 

 directed towards a similar mixed silvery- white and yellow spot which lies at the 

 anal angle; cilia dark brown ; the apical portion of the wing has a somewhat 

 irrorated appearance in the specimen before me (perhaps owing to the abrasion 

 of some of the deep brown scales). 



Hind-wings and cilia, dull brown, slightly paler than the fore-wings. 



Abdomen, deep brown. 



Legs, dull brown, scarcely paler about the tarsal joints.
