ring, and two small elevated black and haiiy dots on each 
ring, except the eleventh, which has only one of larger size; 
on each side of the back is a reddish stripe bordered by 
slender black lines ; and lower down on each side is another 
stripe of a yellow color between two black lines; the under 
side of the body is blue-black. This kind of caterpillar lives 
in communities of three or four hundred individuals, under 
a common web or tent, which is made ao-ainst the trunk or 
beneath some of the principal branches of the trees. When 
fully grown they leave the trees, get into places sheltered 
from rain, and make their cocoons, which exactly resemble 
those of the apple-tree tent-caterpillars in form, size, and 
materials. The moths (Plate VII. Fig. 18) appear in six¬ 
teen or twenty days afterwards. They are of a brownish 
yellow or nankin color ; the hind wings, except at base, are 
light rusty-brown; and on the fore wings are two oblique 
rust-brown and nearly straight parallel lines. A variety is 
sometimes found with a broad red-brown band across the fore 
wings, occupying the whole space which in other individ¬ 
uals intervenes between the oblique lines. The wings ex¬ 
pand from one inch and one quarter to one inch and three 
quarters. The great difference in the caterpillar will not 
pennit us to refer this species to the Neustria of Europe, for 
which Sir J. E. Smith* mistook it, or to the castrends^ 
which it more closely resembles in its winged form. 
Most caterpillars are round, that is, cylindrical, or nearly 
so; but there are some belonging to this group that are very 
broad, slightly convex above, and perfectly flat beneath. 
They seem indeed to be much broader and more flattened 
than they really are, by reason of the hairs on their sides, 
which spread out so as nearly to conceal the feet, and form 
a kind of fringe along each side of the body. These hairs 
grow mostly from horizontal fleshy appendages or long warts, 
somewhat like legs, hanging from the sides of every ring; 
those on the first ring being much longer than the others,
