with a little ochreous intermixed ; third joint annulate with pale ochreous 
at the base, middle and tip ; head ochreous-gray ; antennae with alternate 
annulations of dark brown and pale ochreous ; thorax and anterior wings 
ochreous-gray. There is a brownish patch at the base of the wings, an 
oblique dark brown streak from the costa, not far from the base, crossing 
the fold, but not quite reaching the posterior margin ; extreme costa dark 
brown, a dark brown costal spot about the basal third, another larger one 
about the apical third, the wing between the latter and the dorsal margin 
being overlaid with dark brown; apical portion of the wing densely 
dusted with dark brown; ciliae gray, with some intermixture of dark 
brown scales. Alar ex. % inch. Kentucky. 
The larva is slender, white, with a black spot behind each eye, and 
two small black ones, one above the other, on each side of each segment. 
Later in larval life, the black spots on the first segment spread, and cover 
the posterior margin of the segment, becoming confluent on top ; and the 
larva becomes dirty yellowish, with small black spots on each segment, 
and the space between the segments (or rather where the segments pass 
into each other), becomes suffused with pink. It feeds on the leaves of 
the “ Black Jack” ( Quercus nigra) in the latter part of June and in July. 
G. grisella. WN. sp. 
Gray, densely dusted with dark brown, base of the costa dark brown ; 
head but faintly dusted; antennae dark brown; palpi with the second 
joint densely clothed beneath, but scarcely brush-like, dark brown exter- 
nally, with a white annulation near the apex of the second joint, and 
another at the base of the third. A/ar ex. 5 inch. Kentucky. Imago 
in May. 
G. albistrigella. NV. sp. 
Second joint of the palpi but slightly thickened beneath towards the apex. 
Entire insect (except as stated below) dark brown in some lights, faintly 
tinged with purple, green, or bronze ; a small oblique white costal streak 
just before, and a few indistinct whitish scales or small spots in the apex, 
near the dorsal ciliae; ciliae pale fuscous, with a dark brown hinder mar- 
ginal line before their middle. Alar ex. 34 inch. Kentucky, in June. 
The wings are not spread in my single specimen, and I have not 
examined the neuration. It is rather a pretty species, which in its general 
appearance and style of ornamentation, seems to approach S¢rodvsza, 
Clemens. 
G. suffusella. IN. sp. 
Second joint of palpi slightly incrassate beneath towards the apex; both
