This fine and extremely rare species varies from 23 to 3} inches in expanse. The fore wings are dark grey 
at the base, with a white spot in a dark patch before the middle, followed by an obsolete ashy bar, then a lobed 
reddish bar beyond the middle, edged before and behind with a grey line spotted with blackish, the extremity 
of the wing being greyish-ashy coloured ; the hind wings and body are reddish-grey. The female is much 
larger and paler-coloured than the male, the fore wings reddish-grey with the white spot, and the hind wings 
unspotted. 
The caterpillar is variegated with red, brown, grey, and white, with two blue fascize near the head, spotted 
at the sides with red ; it is tufted with hairs, one thicker than the rest near the tail. It feeds on pine-trees, the 
imago appearing at the end of July. 
Specimens of this moth were contained in several old English collections, but the only recorded instances of 
its capture in England, are a caterpillar taken in September 1748, in Richmond Park, by Wilkes, and a male 
moth captured by Mr. Sparshall in the Norwich Hospital on the 22nd July, 1809, which is now in the 
British Museum. 

GASTROPACHA (sprc. ryp.), OcusennEIMER. 
Neer 
This genus is well distinguished by its robust form, very curved antenne, denticulated wings, thick abdomen, 
(whence the generic name, derived from the Greek,) destitute of an anal tuft, elongated palpi advanced like a 
beak in front, and antennz nearly alike in both sexes. The remarkable appearance which the insects exhibit 
when at rest, as represented in our figure 5, is caused by the dilated margins of the hind wings extending 
beyond the costa of the fore wings, which, joined to the colours of the insects, gives them the appearance of dead 
leaves of the oak and other trees.

This fine insect measures from 21 to 31 inches in expanse. The general colour is dark rich chesnut, the 
extremity of the wings suffused with a pale lilac bloom ; the fore wings with three oblique waved black stripes, 
and a black spot between the two nearest the body ; the hind wings are unspotted, the outer edge redder than 
the rest ; the palpi are black. Varieties occur in the greater or less distinctness of the stripes, which sometimes 
run across the hind wings. . The caterpillar is very large, and remarkable for having the sides of its body 
furnished with fleshy appendages, whence the moth has received the name of the “ Lappet ;” it is dark-grey 
or brownish, with two dark-blue stripes near the head, and with fascicles of hairs, the one on the penultimate 
segment being the largest. The chrysalis is thickly powdered with a white bloom. It feeds on willows,
