Antennae dark brown. (The head is entirely denuded of scales and the lab¬ 
ial palpi have been broken off.) 
I have a single specimen from Mr. A. S. Packard, Jr., collected in 
liabrador. ''

P. Liriodendronella. —Fore wings silvery-white, the posterior portion of the 
wing pale golden, with a broad pale golden streak along the middle of the wing- 
above the fold, arising at its base. About the middle of the costa is a pale gold¬ 
en, oblique costal streak black margined on both sides, which coalesces with the 
posterior end of the median streak. The costal cilia silvery, containing three 
diverging black streaks. The apical spot black, with a silvery scale or two be¬ 
fore and behind it, and at the extreme apex, two black lines in the cilia, diverg¬ 
ing from the apical spot. In the cilia of the hinder margin is a black, curved 
line, and at the beginning of the cilia of the hinder margin, is a dorsal silvery 
spot. Hind wings silvery-gray; cilia the same. 
Antennae, head, labial palpi silvery-white. 
The larva mines the small terminal leaves of the branches of the 
Tulip-Tree. It is without feet. The body tapers from the head, the 
terminal portion being slender and pointed, deeply incised, almost 
moniliform. Head thin and flat. It makes a broad, linear mine oti 
the under side of the leaves^ leaving a brownish “frass” line. The 
mine is much contorted and very long, so as often, if not always, to take 
up the entire under surface of the leaf, winding over it so as to detach 
nearly all the under epidermis. This is extremely delicate and of a 
bluish-white color and often the greater portion of it is detached by 
abrasions. 
The larva may be taken from the beginning to the latter part of 
July. My own specimens were found on the 22nd of July, at which 
time they were nearly full fed. Taken in the latter part of this month 
it is very easy to rear the larva and obtain the most perfect images.

T. Quercitella. —Fore wings orange-yellow, apical portion of the wing red¬ 
dish-brown, dusted with dark brown. Hind wings pale yellowish, towards 
the apex reddish-brown and the apical cilia dark brownish. 
Antennae, head, labial palpi dark orange-yellow. 
The larva makes a white, blotch mine on the upper surface of the 
leaves of oak in September and October. About the middle of the 
mine is a spot whiter than any other part, circular and more opaque.
