attached to the under side of boards, billets of wood, and in. 
similar sheltered situations. The cocoon is about 0.85 long, oval 
w ith the ends rounded, of a dirty gray or pale brown color, and 
with the hairs of the caterpillar woven into its outer surface. The 
moth of this species is most common in May and June, but spe¬ 
cimens occur at all times, coming out even in winter in stove- 
warmed rooms in which caterpillars have happened to secrete 
themselves. It is snow white with a black dot in the centre of its 
wings, and the hind part of its body has a row of black spots 
above and another along each side, with a bright ochre-yellow 
stripe between, and the forward hips and thighs in front are also 
of this last color. Width across the wings 1.50 to 2.00. The 
caterpillars are not stationary, but wander about and feed on a 
great variety of leaves, eating their edges irregularly; aud they 
seem to regard the texture rather than the taste of their food, for 
I have noticed them in the greatest numbers upon trees and plants 
whose leaves are most soft and tender, withering from the slightest 
touch of frost, such as the convolvulus, bean, grape, butternut, 
&e. See Harris’s Treatise, p. 268. 
12ft. Spotted-winged sable, Desmia maculalis, Westwood. (Lcpidoptera. 
Pyralidse.) 
The side of the leaf rolled into a cylinder and tied with silken 
threads, with a slender slightly tapering worm residing therein,0.90 
long, leaf green, having a black U-shaped mark upon its neck aud 
black spots upon the following ring; the pupa formed in the same 
place, the moth coming out the last of June and in July, of a black 
brown color with two large roundish snow-white spots on the fore 
wings and the hind wings with a white band across the middle, 
(broken apart in the female,) and with two white bands on the 
abdomen. Width 0.75 to 1.15. This may frequently be met 
with in all parts of the United States. The males are readily 
distinguished from all the other insects of the order Lepidoptera 
by a most remarkable peculiarity. Their antennae are elbowed, sim¬ 
ilar to those of the weevils, and ants and bees. They have a little 
brush-like tuft of hairs in their middle, jutting out upon one side, 
their first joint being long and thickened towards its tip. See 
Patent Office Report, 1854, p. 78.
