DISEASES OF THE COTTON PLANT.

marked on the margin with an irregular band of dirty 
cream-color, marked with black spots on the extreme outer 
edge. In the centre of each wing was an oblique line of 
the same color ; the body was brown ; the under-wings of 
a dirty, yellowish white, with a dark shade near where they 
touch the upper-wings ; the antennae were threadlike. 
The eggs producing these worms were found deposited 
in clusters in September, and not singly, like those of the 
boll-worm. The old caterpillars are subject to a disease 
which often proves fatal ; and hence it is difficult to raise 
them in confinement. When attacked, they appear to 
bloat or swell very much, become full of a watery pulp, 
suddenly cease to feed, and soon perish, when the outer 
skin turns black, and the inside is found to be full of st. 
liquid, putrid matter. Perhaps, if they were not subject to 
this disease, these caterpillars might do as much damage 
to the cotton as the boll-worm ; but, being generally not 
very numerous, they cannot do much injury. 
The same remedies will do for these worms, or cater- 
pillars, that have been recommended for the boll-worm. 
The Striped Pale-Green Caterpillar. 
There was another cateipillar found feeding upon the 
leaves of the cotton plant, near Columbus, in Georgia,, 
which sometimes buried itself in the bolls, in the same 
manner as the boll-worm. It was about an inch and a 
half in length, of a pale-green color, with wavy, longitudinal 
stripes of a lighter color on the back, and with a longitu- 
dinal black line running down each side, thicker and darker 
on the fore part of the head. Under this was a broader 
line, nearly white, tinged with light red or reddish brown,. 
On each side of every segment was a small black spot. It 
had six pectoral, eight ventral, and two anal feet.
