184 DISEASES OF THE COTTON PLANT. 
previously fastened the other end of this thread to the leaf 
from which it had feUen. The leaves attacked by this 
moth can be distinguished from those that are perfect, by 
their roUed-up and distorted appearance ; and either this 
insect, or one very similar in habits and appearance, some- 
times 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 fall 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 pectoral, eight ventral, 
and two anal feet ; the two anterior pair of pectoral 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 
are formed in semi-transparent cocoons of loose silk 
among the leaves; and in about foaiteen days, the perfect 
moths come out. The moth at rest has a somewhat bell- 
shaped appearance, 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 middle ; 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 under- 
side is yellow and more or less shaded. 
I should judge, from the small numbers of these cater- 
pillars, that they do comparatively little if any injury to 
the main crop, and no doubt the moths would be attracted
