ish-yellow, barred in the centre with two triangular black marks ; 
the ends of wings diamond-shaped, of a light color ; the upper part of 
the thigh is black ; and the rest of the leg yellowish. 
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 men- 
tioned above, unobserved 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 holl-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 reduvii or cimicidsB, 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 
enquiries on the subject. 
SAP-SUCKERS. 
Another insect, (PI. VII. fig. 5,) 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 antepme 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 ; the antennae are brown and green, the eyes 
brown ; the thorax somewhat triangular ; the anterior part green, 
and shaded with reddish-brown, posteriorly ; the legs, brown and 
green ; the wing-cases with a cross, shaped like the letter x, forming 
four triangles, those nearer the thorax being reddish-brown ; the side 
triangles aro green. 
I observed these insects, when confined under glass, sucking the 
sap from the buds and young bolls, their only food. The young 
eventually completed their transformations into perfect insects. They 
were observed, moreover, to eject large drops of green sap from their 
abdomens, which could only have been procured from the buds them- 
selves. As it has been already seen that these insects puncture the 
bolls and extract the juices therefrom, the question arises whether 
they do any material injury, either by this extraction of the sap, or 
by a poisonous sting, like some of the reduvii. 
There is likewise another of the same species of insect, (PI. 
VII. fig. 6,) which was found perforating the young flower-buds and 
bolls of the cotton, similar to the above. The head and anterior por- 
tion of the thorax are reddish-brown, the remainder of the thorax 
yellow, with a double dark mark in the middle,; the wing-cases are 
brownish-black, with two longitudinal yellow lines from the upper
