3. Aridalia f sp. 
This caterpillar occurred at Providence June 10, both on the pig- 
hickory and liop-liornbean. Though they were abundant, they did not 
live in confinement. 
Larva. — Body very slender; head large, flattened in front, otherwise full, rounded, 
aud wider than the body, which is very slender, of uniform thickness, with no tuber- 
cles; smooth, with a prominent lateral ridge. Anal legs large and broad ; supra-anal 
plate large, equilaterally triangular. Head, body, aud legs yellowish greeu, with 
no spots. Length, I2 mm . 
4. Coleophora oitrija 1 Clem. 
The larva, according to Clemens, mines the leaves of iron- wood (Ostrya 
virginica) in October and during spring. 
The case is flat, rather wide, and the edges nearly parallel except 
near its mouth. The upper edge is slightly curved, and almost at the 
hinder end is a slight notch, which is sometimes wanting, and the 
hinder end is squarely excised. Color of the case pale reddish-brown. 
5. Aspidisca 08tryoefolieUa Clem. 
The larvaB may be found on the leaves of iron-wood during the latter 
part of September and early in October. 
About the 10th of October all the mines are untenanted. There may 
be a spring brood in the leaves of the Ostrya, but I have not observed 
any. 
The mine is large when compared with those found in the leaves of 
other plants, and the hole left by cutting out the disk is out of propor- 
tion to the size of the mined portion. (Clemens.) 
6. Xepticula 08trya?foliella Clem. 
The larva in July and August makes a rather wide, most frequently 
much contorted, transparent mine, with a narrow, central, black line 
of •• frass; n sometimes the early portiou of the mine is filled up with 
" frass," and in others the line of " frass" is distinct from the beginning. 
From the middle to the end of the mine whence the larva escapes it will 
average nearly a line in width. (Clemens.) 
T. X'jiticula virginiella Clem. 
In the leaf of iron-wood, Ostrya, it makes a very narrow long track, 
not broader than the width of the larva, the interior of which is filled
