-pale body sparsely covered with tine whitish hairs. They pass 
through about six moults, the color and markings varying after each 
successive moult. .. . , , n „ 
When full grown the worm is of a deep black color and sparsely 
clothed with tine soft yellowish hairs, which are of unequal lengths 
and rather more numerous toward the head; those on the head turn 
forward partially shielding the head. There is a white dorsal stripe, 
on which are situated numerous black dots, starting from the pos¬ 
terior margin of the first segment and traversing the whole length 
of the body posteriorly; the anterior margin of the segment is white 
and two small square yellow spots are on the top; on each side 
of the dorsal stripe are numerous line crinkled black lines on a yel¬ 
low ground; a transverse oval blue spot on the side of each segment 
and situated anteriorly to it a deep velvety-black ones the lower 
region of the side is mottled with blue and yellowish the latter m 
short uneven lines. The underside of the body is black, pro-legs 
tipped with white. Head black, covered with short black hairs. 
Length two inches. , ^ 
The favorite food plants, are Black Cherry and Apple on the 
leaves of which they feed until they are nearly full-grown, when they 
leave the tree and disperse in different directions eating whatever 
food comes in their way that is palatable, to them, each one finally 
seeking a sheltered nook or crevice in which to transform, lhe co¬ 
coon is oblong-oval, yellow. , 
The eggs are firmly glued together, forming a mass around the 
twig near the end, and are thickly covered with a glutinous coating 
which protects them from the weather. 
Clisiocampa sylvatica, Harr. 
This, like the preceding, is a 
tent caterpillar and is known 
as the Tent-caterpillar of the for¬ 
est. They are hatched from eggs 
placed in a mass around a twig- 
something similar to those of the 
Fig. 36—Clisiocampa sylvatica. Americana, though being placed 
more regularly, and the ends of the mass, are in a true ciicle, mak¬ 
ing a band around the twig of uniform diameter. . . 
As soon as the worms come forth they commence spinning a web 
which is much less conspicious than that of the 01 chard caterpillai, 
attaching it closely to the branches and trunks ol the tiees infested, 
they also congregate on the outside of the web when they are about 
to pass through a moult. When about half-grown they lea-\e the 
tree on which they have been feeding and travel singly fiom one 
tree to another or from place to p)ace in search of a shelteied letieat 
in which to spin a cocoon and which they finally form by diavmg 
the edges of a leaf together or by fastening together several leaves; 
it also spins a cocoon in a similar form and situation to the Amci- 
XCCL1T. CL 
This larva reaches maturity after the fourth moult. It is then of 
a pale blue color and in form and size closely resembles the com¬ 
mon species. The following is Dr. Fitch’s description:
