passing thence to the costa, thence to the fold and backwards and forwards 
from the costal margin to the fold, to about the apical fourth, where it sud- 
denly curves up to the dorsal margin at the beginning of the ciliæ. In some 
lights this line is invisible. Alar ex. 34 inch. Kentucky, in May.

Second joint of the palpi a little incrassate beneath. Lower face creamy 
yellow; palpi, head, thorax, and anterior wings dark brown, a little 
bronzed, rather indistinctly dusted with ochreous, and still more indis- 
tinctly with white. A/ar ex. ss inch. Kentucky. 
The larva mines the leaves of the ‘Ground Cherry” (PAysalis 
Viscosa,) in September, and perhaps earlier, as I found there many empty 
mines. It mines the under surface, and produces a tubicular swelling of 
the upper surface. It pupates among leaves on the ground, and (in the 
breeding cage at least) the imago conceals itself among the leaves and 
trash” on the ground. I have never seen any specimens except the 
two that I succeeded in rearing; but the mines are abundant. The. 
following are my notes about the larvae :—“ Larve now (Oct. 6th) about 
34 inch long; one of these in the mine appears bright bluish-green, with 
the head yellowish ; another is pale bluish or bluish-green, almost white, 
suffused with pink upon the back, head pale brownish. Oct. 7, one of 
them has left the mine; it is 14 inch long, robust, deep purple, with the 
head and ‘shield’ of the first segment green. Two imagines April 14.” 
They were kept in a warm room. 
G. quercivorella. NN. sp. 
Second joint of the palpi slightly incrassate beneath. Palpi very dark 
brown, mixed in almost equal proportion with white. Head white, rather 
sparingly flecked with dark brown. Antennæ dark brown, annulate with 
white ; thorax and anterior wings dark iron gray, with a blackish costal 
spot about the middle of the costa, and another smaller one at the begin- 
ning of the cilia, and with other irregular and irregularly disposed dark 
_ brown spots on the wing; the dorsal margin paler gray. Hind wings 
of a leaden hue, faintly tinged with purplish. Adar ex. 7 inch. Imago 
in June in Kentucky. 
The larva is white with bright red spots, closely resembling that of 
G. Hermonella. It feeds on Oak leaves, and when first observed, was 
forming a closely-fitting tube of white silk around itself on the under side 
of the leaf. This tube it closed ina day or two after, and by some means 
spun a band of brown silk across the middle of it on the outside,
