478 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
coiu*, toward tbe larger end. When about to pupate, the caterpillar 
draws a portion of a leaf around it, lining it with silk, thus forming a 
delicate cocoon. 
Larva.— Body spindle-shaped, and somewhat stout in proportion to the length. Pea 
green, ftboat the color of the underside of the leaves of the bass-wood. The usual 
waits an present, of a dull brownish eolor and emitting pale hairs. The head, tho- 
fthield, and legs are pitchy black, while the mouth-parts are a little lighter, and 
th»re is a small black spot on each side of the first segment back of the head, just iu 
front of the spiracle. The anal plate is dull brownish. Length, 25 nuu when at rest, 
and 30""" when in motion. (Fernald, Can. Ent., xvi, p. 2~>.) 
7. Lithocolletia lucetieUa* Clem. 
The larva mines the under side of the leaf of Tilia americana (bass- 
wood) in July, September, and October. The mine is most frequently 
nearly square in form, and when completed both cuticles of the leaf are 
left nearly transparent, and the leaf is not folded. The " frass n is cast 
on the edges of the mine. It weaves an oval cocoon, thin enough, how- 
ever, to permit the pupa to be seen through the cuticle. The imago 
appears iu August aud May. 
Larva. — The larva is cylindrical. The head pale brown; the body pale greenish 
white with a series of dorsal brown spots from the third ring posteriorly. 
Moth. — Antenna silvery. Head, tuft, and thorax silvery. Anterior wings silvery 
from the base to the middle, and thence to the tip golden, with a golden costal streak 
from the base not extended to the middle. About the middle of the wing is a silvery 
band, broadly margined internally with golden, and with a minute black point on the 
costa internally ; a costal silvery spot, margined internally by a black spot, nearly op- 
posite to which is a large dorsal silvery streak margined internally by an obliqueblack 
Vine; near the tip is a costal, silvery, nnmargined streak curving to the tip; cilia 
golden at the tip, and on inner margin silvery. No apical spot nor hinder marginal 
line. Hind wings silver-gray, cilia the same. Abdomen blackish, tipped with silvery 
gray. (Clemens.) 
8. Coleophora tiliafolieUa Clem. 
The larva feeds on the leaves of the linden from the beginning to the 
latter part of May, and enters on pupation in the latter days of May or 
early in June. 
The case is black, somewhat pistol-formed ; straight along the upper 
edge, turned abruptly down so as to form a handle-like appendage be- 
hind, with a toothed, flattened projection about the middle of the under 
edge, whence to the mouth of the case it is cylindrical. 
At this date the larva does not mine the leaf, but eats holes in it, de. 
vouriug its substance. The case is fixed to the under surface of the leaf, 
and is easily seen, even on the leaves of the higher branches. 
Larva. — The body of the larva is dull, dark-brown aud the dorsal plates and head 
black. (Clemens). 
*I received five specimeus of this from Dr. Clemens; it is very distinct from any 
European species. The exp. al. (omitted by Dr. Clemens) is 3£ lin.— H. T. Stainton.
