found an elytron of this beautiful beetle under 
the bark of the willow in Northern New York

INJURING THE LEAVES. 
5. Theclaf sp. 
The larva lives in an oval chamber between 
two leaves, the upper leaf being concave over 
the site of the caterpillar. 
A caterpillar of a Thecla f occurred on the 
willow September 3, at Brunswick, Me. 
Larva. — Head deeply divided on the vertex, much 
narrower than the body ; pale horn color, with short 
hairs ; black around the eyes and mouth-parts, also on 
the occiput, this black stripe usually concealed by the 
prothoracic segment. Body broad oval cylindrical, pale pea-green, with a slightly 
frosted appearance, due to numerous fine close white dots ; two whitish subdorsal 
lines, fading out on the supra-anal plate. On the under side of the body are white, 
short, unequal hairs. Thoracic feet greenish, amber at tip. Length 17 to 18 mm . 
6. Thanaos sp. 
This Hesperian caterpillar occurred on the willow at Brunswick, 
Me., August 20. (See p. 459.) 
Larva. — Like that on the aspen, but the head is not so wide and is rather fuller, 
and entirely dull black. Otherwise the body, the color, the widely-separated sub- 
dorsal white lines, and the white granulations are the same. Length, 13 mm .

Smith del. 
7. Sphinx htscitiosa Clemens. 
Rev. Mr. Hulst states, according to Professor Fernald, that this rare 
species has been bred from the willow, but the larva has not yet been 
described, and nothing more is known of its habits. 
Moth. — Head and sides of thorax gray. Back part of the head above and the upper 
part of the thorax black, the latter with a f«w blue and gray scales on the back part. 
A broad brown stripe extends from the middle of the palpi back under the wings. 
The abdomen is dull ocher-yellow (gray in the females), with a black line along the 
middle and a black band broken by dull yellowish white on the edges of the seg- 
ments along each side. The under side of thorax and abdomen is pale gray. The 
forewings are pale brown, with the margins sooty black. The band on the outer 
margin is narrower towards the apex, and has the inner edge wavy. More or less of 
the veins are black, and a black line extends in along the middle of the cell from 
the whitish discal dot. This line is double at first, but the two parts unite rnwardly. 
A short black dash rests on the intervenular spaces as far as the apex, the last form- 
ing the oblique apical streak. Fringes black. The hind wings are bright ocher- 
yellow (grayish in the females), with a broad black terminal border and a faint
