NATURAL SCIENCES OF PHILADELPHIA. 209 



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. Fore wings pur- 

 plish brown, without violet and greenish reflections, 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 Nysssefoliella, they are rather deep 

 purple. 



The larva mines the leaf of 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, without 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. 



Aspidisca. 

 (See Proceedings, Jan'y., 1880, p. 11.) 

 The diagnosis of this genus was made from two specimens of A. splendorife- 

 r e 1 1 a. In insects so extremely small and fragile, even when relaxed by mois- 

 ture, it is no simple task to make a correct diagnosis from a single examina- 

 tion. The reader will therefore please correct in the January number of the 

 Proceedings as follows : Labial palpi extremely short and slender, much separated. 

 Tongue naked and scarcely as long as the anterior coxa;. 



A. lucifluella. Head silvery. Antennae rather dark fuscous. Fore 

 wings silvery from the base to the middle, and thence to the tip dark fuscous 

 varied with golden. Near the tip are three short, costal silvery streaks adjacent 

 to each other ; the first is longer than the others, with converging dark mar- 

 gins, and a golden patch on its internal side ; the second with straight dark 

 margins, and a golden patch beneath and adjoining it ; the third is unmar- 

 gined except by the external margin of the second streak which separates 

 them. Opposite the first costal streak is a dorsal, tapering streak of the same 

 hue, and placed in the dark fuscous portion of the wing. From the second 

 golden spot to the middle of the hinder margin is an oblique silvery streak, 

 sometimes separated into two spots. At the extreme apex is a deep black 

 triangular spot ; the cilia grayish, tinged with pale brownish. 



The larva may be found in September and October mining the leaves of 

 hickories. The head, first and second segments are brownish, with a reddish 

 tinge ; body brownish-green, with a dark green vascular line and three black- 

 ish dorsal spots on the middle segments. Early in October the larva cuts out 

 an oval disk and enters the pupa state, to appear as an imago early in June. 

 The perfect insect is larger than splendoriferella. 



Pakectopa. 



The fore wings are lanceolate. The disk is acutely closed behind, at the 

 apical third of the wing and narrow. No costal nervure. The subcostal sends
