DISEASES OF THE COTTON PLANT. 
191 
part of tlie thigh is black, and the rest of the leg yel- 
lowish. 
This insect is more especially mentioned here in order 
to draw attention to the various tribes which attack the 
terminal shoots of cotton, as at present very little appears 
to be known about them, and immense numbers of young 
buds dry up and fall in the manner mentioned above, un- 
observed from their minute size. Many of them are, no 
doubt, cast in consequence of atmospheric and various 
other causes, but as this small insect has been observed 
sucking the juices from the plant, it may be found that 
several others do the same thing in different localities. 
The young boll-worm is, no doubt, found in these shoots ; 
but I very much doubt whether the fallen blackened buds 
are owing to injuries received from it, as will be seen in the 
article on that worm. It is true, the young boll-worm 
causes many immature forms to drop, but in such cases the 
bud attacked generally shows where the injury has been 
done by a small puncture. 
As several of the Beduvii or Cimicidce have the power 
of stinging man and animals in a very severe manner, with 
their probosces, or piercers, may they not in some measure 
possess the same power over vegetable life ? The question 
is merely asked to lead to further inquiries on the subject. 
Sap-Suckers. 
Another insect found in the young shoots and newly 
formed bolls, the color of which is green ; the eyes reddish 
brown ; the legs green, with the thighs red ; the antennae 
are four-jointed, and also green, with red at the end of 
each joint. The pupa is about a quarter of an inch, and 
the perfect insect is seven-twentieths of an inch, in length ;
