 AND DESCRIPTIONS OF NEW SPECIES. 



By Lord Walsingham. 



[Continued from page 286 of Vol. U.] 



COPTOTRICHE gen. nov. 



Ko-telv = to cut ; Opts = a hair. 



Tischeria complanoides F. & B. = latipennella Chamb. 



Antenna?,, $ , ciliated, a minute projecting hair pencil from the basal joint beneath 



Labial palpi, dependent, scarcely longer than the head. 



Haustellum, rather long. 



Head, clothed with an erect tuft above ; face smooth. 



Fore-wings, lanceolate, pointed, clothed with long cilia commencing abruptly at the 

 outer end of a distinct cuticular fold which extends from near the base of the 

 costal margin to three-fourths of the wing-length on the underside, and is of 

 nearly even width throughout; beneath the fold two-thirds of the wing-surface 

 is thickly clothed with long hair-like scales arising most conspicuously from the 

 submedian vein. Neuration, 9 veins, apical rein forked, the branches ending on 

 opposite sides of the apex ; the remaining veins simple. 



Hind-wings, lanceolate, as wide as the fore-wings, the costal margin suddenly de- 

 pressed at the outer fourth, ending in a sharp point almost in a line with the 

 dorsal margin ; the first half of the costal margin is clothed with very long cilia, 

 and the cilia on the dorsal margin are also very long, but at the depression above 

 the apex these are abruptly shortened, giving an excised appearance as if 

 caused by an injury. 



Abdomen, anal tuft moderate; terminal segment ending in a pair of well-developed 

 lateral claspers, uncus apparent.

 ments of male — enlarged (Walsingham del). 



This genus differs from Tischeria in its much wider hind-wings, somewhat abruptly 

 pointed downwards at the apex, in the long tufts of hair-like scales on the under- 

 side of the fore-wings, aud in the conspicuous costal fringe along tbe basal two-thirds 

 of the hind-wings and in the excised appearauce of the costal cilia above the apex. 



Coptotriche complanoides F. and B. 



Tischeria complanoides F. and B. (zellerella F. aud B.) 

 n. syu. =Tischeria latipennella Chamb. 

 (!=Tischeria zelleriella Clem.) 



Clemens described zelleriella [Proc. Ac. Nat. Sci. Phil., 1859, 326. (Stu. Tin. N. Am., 

 81) ] as having bluish-gray hind-wings, the fore-wings yellowish running to reddish 

 saffron towards the tip. He mentions also a supposed female entirely reddish-ferru- 

 ginous.
