orange colored pencils and two shorter white ones on the side. The 
eleventh segment has two long white pencils directed backward. 
Venter bluish-white, marked with a tinge of yellow. A row of 
fuscous spots on the lower lateral border. Head, black. Length,

The caterpillar is of a bright yellow color, sparingly clothed with 
long and fine yellow hairs on the sides of the body, and having 
four short and thick bush-like yellowish tufts on the back on the

fourth, fifth, sixth and seventh segments. On the first segment 
are two long black pencils of hairs that extend forward, somewhat 
diverging. From the top of the eleventh segment is a single black 
pencil extending backward. Head and two little retractile warts on 
the ninth and tenth segments coral read, and a narrow dorsal 
stripe of black or dark brown, with a wider lateral stripe a little 
lighter. 
There are two broods of the worms, in June and September. They 
feed upon the leaves of Apple, Rose, Oak, Maple, Elm, Plum, Pear, 
Horse-chestnut, Black Walnut, Larch and Spruce. The cocoon is 
attached to a leaf, which is also attached by silken threads to the 
twig. The moths issue from the cocoons in about ten days from 
the time the larva enters the chrysalis state. 
Limacodes laticlavia, Clem. 
The larva feeds on Maple. 
Empretia stimulea, Clem. 
Larva—“Body semi-cylindrical, truncated obliquely before and 
behind, with a pair of anterior long fleshy, subvasculqr slenderly 
spined horns, and a smaller pair beneath them. The superventral 
row of papillae are rather large and densely spined. After the last 
moulting, the longer horns become moderate in length. The portion 
of the body between the anterior and posterior horns is of a fine 
bright green color, bordered anteriorly and superventrally by white, 
which is again edged by a black line. The horns, papillae, and an¬ 
terior portion of the body, are reddish brown, with a small yellow 
spot between the anterior horns, while the posterior pair are placed 
in a yellow patch.”—(Morris.)
