INSECTS INJURING OAK-LEAVES. 139 
the 10th and 11th segments there is a smaller red tubercle notched at the top. The 
whole surface of the body is somewhat hairy, but along each side the hairs are long 
and form quite dense clusters. 
Pupa. — From £ to 1 inch long, varying in color from chocolate to reddish brown. 
Moths. — The male is very much smaller than the female and with broadly pectinated 
antennae. It is of a yellowish-brown color, with two dark brown lines crossing the 
fore-wings, one at the basal third, the other on the outer third, somewhat curved, 
and with teeth pointing outwards on the veins. The outer end of all the wings is 
dark brown. A curved dark brown spot (reniform) rests a little above the middle of 
the wing, and a small round spot of the same co?or (orbicular) is situated between 
this and the base of the wing, just outside of the inner cross line. A similar spot 
rests near the middle of the base of the wing. The fringes on the fore-wings are 
dull yellow sh, and broken by eight brown spots. The antennae are strongly bipec- 
tinated, or feather-like. The fore- wings expand about an inch and a half. 
The female is pale yellowish white, with dark brown cross-lines and spots similar 
to those of the males. The cross-lines in both sexes are much darker and more prom- 
inent on the forward edge of the wings (costa) than elsewhere. In some specimens 
there is a faint stripe of brown across the middle of the wing (median shade), and a 
toothed line across the wing near the outer edge (subterminal line). The fringes of 
the fore-wings have eight dark spots between the ends of the veins, as in the males, 
and similar but fainter spots often occur in the fringes of the hind wings. The body 
is much stouter than in the males, and the antennas are not so heavily feathered. 
The expanse of the wings is from If to 2f inches.

Although this caterpillar has been raised from the raspberry by the 
late Mr. G. A. Shurtleff, near Boston, we have found it common on the 
scrub oak in Providence as late as October 1, some specimens before the 
last molt occurring September 20 to 27. This curious woolly caterpillar 
will attract attention from its peculiar appearance. 
As we have elsewhere stated, the cocoon is rather long, cylindrical ; 
its texture is dense, being formed of the hairs of the larva, closely 
woven with silk. When the pupa, which is very thin, is about to 
transform it escapes from the cocoon, as the cast skin is found with the 
tip of the abdomen remaining in the cocoon. In this respect the moth 
is a connecting link between the groups represented by Orgyia and 
Limacodes. 
Full-grown larva. — Body short, broad, and flat, head deep honey-yellow; jaws 
darker; the head very retractile within the large prothoracic segment, whichis large 
and fleshy, produced down around the face like a hood, so as to entirely envelop the 
head, so that it is not seen while eating, with a large V-shaped incision in front. The 
body densely covered with hairs, so that the caterpillar appears about one-half as 
broad as long, rounded at each end, the hairs very long and curly ; those on the 
thoracic segments mouse-gray; all the rest behind a uniform pale fawn-brown, some- 
times above a dark, rich orange-ochero.us ; a slight dorsal broad crest, a subdorsal 
broad ridge, and the hairs spread out on the side, but everywhere so long and dense 
as to entirely conceal the head and body. The sides are mouse-gray as above, but 
the lateral hairs are not to be seen from above. The body is pale whitis'i yellow, the 
thoracic and abdominal legs also pale dull yellowish white. The first pair of thoracic 
legs are smaller and nearer together than the others, while there is a pair of rudi- 
mentary abdominal legs on the second and seventh abdominal segments. Length, 
20-32 mm ; breadth, 10-15 ,nm ; height, 7 mm .
