the tender leaves ; but have been caught in the very act of devouring 
the petals of the flowers in the fields of Georgia, as late as the month 
of November ; but, as at this time the grass on which they usually feed 
abounds between the rows, the damage done by them to the general 
crop is but slight. 
Several species of grasshoppers, or locusts, infest old cotton and 
grass-fields, some of them being of large size and possessing great 
powers of flight. (PI. VI. fig. 3.) It may, however, be observed, 
that the true locust is not the insect generally known by that name 
in the United States, which is in reality a harvest-fly, (cicada,) 
usually inhabiting trees, where it makes an incessant buzzing noise 
which may be heard at a great distance during the summer and 
autumnal evenings. The shape of the harvest-fly is much clumsier 
and broader than that of the real locust, and the under wings are not 
folded up like a fan, under a wing-case, but transparent, stiff", and 
veined. 
The real locust is similar to the grasshopper in shape, but the body 
is more robust, the antennae shorter, and its flight much longer and 
more vigorous. Its under-wings, also, when at rest, are folded up in 
fan-like plaits under the outer wing-covers. Grasshoppers and locusts 
are produced from eggs as perfect insects, with legs and antennae. 
They are able to run about and leap with great agility, but are en- 
tirely destitute of the rudiments of wings, except in the pupa state. 
It is only the perfect insects which are able to perpetuate their kind. 
They are generally furnished with ample wings which enable them 
to fly from field to field. Grasshoppers and locusts do much harm, 
when very numerous, to grass and vegetables, and even to fruit-trees, 
as well as to cotton. Turkeys, ducks, and other fowls feed upon them 
with great avidity, and are very useful in diminishing their numbers. 
In some of the Northern States, they have been destroyed by means 
of sheets spread upon poles, so as to sweep them into a bag fastened 
behind, which is drawn over the fields infested by them ; they are 
then killed by means of boiling water or fire. 
THE LEAF-HOPPER. 
( Tettigoma ?) 
The leaves of the cotton-plant are often injured by the leaf-hopper. 
(PI. VI. fig. 4.) This small insect is found upon the plant in the 
larva, pupa and perfect state. In all these forms, it sucks the sap 
from the leaf, causing small diseased and whitish-looking spots, much 
disfiguring the foliage, and injuring the plant itself, when the insects 
are very numerous. They are also found in great numbers on grape- 
vines, in Florida, and injure the foliage to a considerable degree. 
The perfect insects are very small, measuring only from one-tenth 
to three-twentieths of an inch in length. The head is somewhat cres- 
cent-shaped, of a green color, with two red spots on the upper surface. 
The thorax is also green, with two crescent-shaped spots of red on 
each side of a small red spot in the centre. The wing-cases are green, 
with two stripes or bands of red, running parallel down each wing-
