from its mouth, having previously fastened the other end of this thread 
to the leaf from which it had fallen. The leaves attacked by this moth 
can he distinguished from those that are perfect, by their rolled-up 
and distorted appearance ; and either this insect, or one very similar 
in habits and appearance, sometimes attacks the young and tender 
ends of the cotton-shoots, which are often seen webbed up into a mass 
and partially eaten out. 
The caterpillar, when full grown, is about an inch in length, of a 
bright-green color, with a brownish or black head, and has a helmet- 
shaped black mark on the first segment of the body. It has six pec- 
toral, eight ventral, and two anal feet ; the two anterior pair of pec- 
toral ones being dark-colored. 
The chrysalis measures from three-fifths to seven-tenths of an inch 
in length, is of a brown color, somewhat spiny, and furnished with 
four hooks at the end of the tail, by which it is enabled to hold fast to 
its web. The chrysalides were formed in semi-transparent cocoons of 
loose silk among the leaves ; and in about fourteen days, the perfect 
moths came out. The moth at rest has a somewhat bell-shaped ap- 
pearance, the upper-wings suddenly becoming quite broad a short 
distance from the thorax. They are of a chestnut-brown color, with 
an oblique dark-brown band forming an obtuse angle near the mid- 
dle ; and, on the inner margin of each wing, a rather more indistinct 
band runs near the body. The tips are also banded with dark-brown. 
The under wings are yellow, with a blackish-colored mark on their 
margins and sides, while the uiulcr-side is yellow and more or less 
shaded. 
I should judge, from the small numbers of these caterpillars, that 
they do comparatively little, if any injury to the main crop, and no 
doubt the moths would be attracted by lights or fires placed in the 
field at night, as recommended for the .moth of the cotton-caterpillar. 
The same plan would also serve to diminish their numbers, should 
they ever increase. 
THE YELL0W CATERPILLAR 
There is a yellow, hairy caterpillar found on the cotton-plant in 
September and October, which devours the leaf. The specimens ob- 
served in South Carolina and Georgia appeared to be of solitary 
habits, not congregating together, like the cotton-caterpillar anil 
grass-worm, but feeding alone on the plant. 
The young of these insects are of a much lighter color than those 
nearer maturity. The ground color of the old caterpillar is yellow, 
profusely specked and shaded with small black dots ; a yellow longi- 
tudinal line runs along the side below the spiracles ; on each segment 
of the body, rise numerous small yellowish-brown excrescences, or 
warts, from which issue tufts of loug brownish-black hairs. The 
head is black, with a yellow stripe running down the middle. It has 
six pectoral, eight ventral, and two anal feet. Tke cocoons are ovoid 
in shape, formed on or near the surface of the ground, and constructed 
of silk intermingled with gravel, particles of soil, and the hairs from 
their own bodies. These caterpillars are reputed to be capable of
