that eats up the “sponge” of these galls leaving the central cell, the 
imago of which I do not know, but I suspect its normal food is oak- 
leaves, because I have found a very large Notodontade larva, which I 
know usually eats oak leaves, engaged in the same operation. I know

Gracilaria coroniella, n. s.—Fore wings dark yellowish, overlaid with purple. 
Uear the middle of the costa is a large triangular, pale yellow patch, the angle 
of which terminates at the fold of the wing and containing on the costa three 
or four purplish dots. A little posterior to the triangular patch is a small costal 
pale yellow spot. The apical portion of the wing is yellowish; cilia is yellow¬ 
ish tipped with black. Hind wings shining gray, cilia dull dark gray. 
Head dark yellowish. Antennae dark fuscous, very slightly annulated with 
yellowish. Labial palpi yellowish, terminal joint dark brownish exteriorly. 
This is a very handsome insect. I have a single specimen from Il¬ 
linois for which I am indeb:ed to Mr. B. D. Walsh. His specimens 
were taken in the winter, under the loose bark of trees and conse- 
^ quently the imago hybernates.

A single specimen from Mr. B. T). Walsh, and a specimen in the

Besides the foregoing I am indebted to Mr. Walsh for some speci¬
