DISEASES OF THE COTTON PLANT.

have been mucli on the increase for the last ten years, which 
I attribute to the excess in planting, as well as the want of 
proper efforts for their destruction." 
It has been stated by other planters, that the faeces of 
the insect produce the reddish or greenish stain, and that 
the red-bugs will collect where there are splinters or frag- 
ments of sugar-cane. Advantage has already been taken 
of this habit to collect them by means of small chips of 
sugar-cane, when they may be destroyed by boiling water ; 
and as they also collect around piles of cotton-seed, they 
may thus be easily decoyed, and then killed, either by fire 
or hot water, when congregated. AU stumps and dead 
trees standing in the field should be well burnt out. The 
experiment of destroying them by means of the crushed 
sugar-cane and poison has been tried ; but, as no report of 
the experiment has been received, it remains doubtful 
whether it can be recommended or not. 
INSECTS FOUND IN THE COTTON FIELDS— NOT INJURIOUS 
TO THE CROP. 
(Zanthidia niceppe,) 
There are many other insects found in cotton fields, 
which are perfectly harmless to the plant, although the 
larvae of many of them subsist upon the weeds which grow 
between the rows or around the edges of the plantation. 
Among these insects we find butterfiies, in general, one 
species of which is frequently seen hanging over the 
ground by hundreds, around moist and damp places. The 
caterpillar of this fly is of a deep-green, velvety appearance, 
with a yellowish longitudinal line running down each side. 
It was found upon the Cassia Marylandica, and measured 
an inch and one-fifth in leng-th. The chrysalis is greenish.
