shown on the separated epidermis as a white line or streak. 

 The head of the larva is brown; the body uniform pale green ; 

 first segment brownish, with a short vascular greenish streak. 

 When the pupation begins the leaf is thrown into a fold, 

 which is carpeted with silk, and the pupa lies within it. 

 This state begins about the latter part of September, and the 

 imago appears early in May.

. d»A. Isabella. Head golden. Antennas purplish-brown. 

 Fore-wings purplish-broivn, without violet and greenish reflec- 

 tions, with a pale-golden band near the base, inclined toward 

 the base, not constricted on the fold, but broadest on the inner 

 margin. Near the tip of the wing is a small pale-golden 

 costal spot, and one of the same hue nearly opposite on the 

 inner margin. The hind-wings have a greenish reflection; 

 in Nysso?foliella they are rather deep purple. 



The larva mines the leaf of the Isabella grape in September. 

 Its head is brown ; the body yellowish-white, with a few black 

 dorsal spots on a dark-green ground, on the middle segments 

 and beneath a spot on the fourth and fifth segments ; first 

 segment dark green. It cuts out a very large, nearly round 

 disk, during the latter part of September, and appears as an 

 imago in the latter part of May.

X l ;_ A. viticordifoliella. The larva mines the leaves of wild 

 ' t grapes. Its head is brown ; the body yellowish-green, with- 

 out dorsal or ventral spots ; the first ring brown. It may be 

 taken in August, and in the beginning of September it cuts 

 out a small oval disk and enters the pupa state. I have not 

 succeeded in breeding the imago, but have no doubt it is 

 specifically distinct from any heretofore described.
