DISEASES OF THE COTTON PLANT.

The wings of the male measure, when expanded, from 
nine-tenths of an inch to an inch across, and are white, 
with one or two black dots near the centre of the upper 
pair ; the eyes are black ; the antennae feathered, and the 
two fore-legs of an orange color. 
The female is much larger than the male, measuring 
about an inch and one-fifth across the expanded wings. 
She is very similar to the male in <!olor, but has no black 
spot on the upper-wing ; nor are the antennae feathered as 
in the male. 
I consider, from the circumstances under which the 
nest, or web, of caterpillars was found, that it was accident 
alone which caused their presence on the cotton, as I have 
never seen them before nor since, in any number, among 
the plants. Therefore, they may be classed among 
those insects which cause little or no harm to the general 
crop. 
These moths are similar to the Arctia textor of Harris, 
but appear to differ from them in the spots on the upper- 
wings of the male, and in some other slight particulars. 
The habit of webbing up the limbs is also the same. 
INSECTS FOUND ON THE TERMINAL SHOOTS. 
The insects attacking the terminal shoots of the cotton 
plant are at present very little known; but when their 
habits shall have been more thoroughly investigated, there 
is no doubt that they will be found to be much more de- 
structive than is generally supposed. 
No practical planter can have passed through his cotton 
fields, without frequently observing that the terminal leaves 
of many of the plants have been webbed up and eaten out, 
or that many of the young blossoms have suddenly turned
