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. 



ANTISPILA. (See Paper No. 3.)* 



A. Isabella. Head golden. Antennae purplish-brown. 

 FoYQ-wmgs purplish-brown, 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 rejection; 

 in Nyss&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. 



A. viticordifoliella. The larva mines the leaves of wild 

 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.
