[8] REPORT 4, UNITED STATES ENTOMOLOGICAL COMMISSION. 
of the same height as the surrounding cotton, but has fewer maturing bolls. A part 
of this young cotton is in a hollow, where it grows very tall ami rank ; the remainder 
•stretches up the hill-sides on either hand. The portions on the hill-sides'are now very 
much " ragged," some plants having nearly every leaf eaten. The portion in the bot- 
tom is least attacked of any, though not by any means free from worms. The worms 
in this young cotton are beginning to web up in large numbers. Of the leaves now 
lieing folded, the greater number contain larva} just beginning their webs; next in 
point of numbers are leaves containing larva} not yet in pupa; and last, fully formed 
pupa}. I gathered at random 25 or 30 pupa 1 , all of which had their full color.' All the 
pupa- were placed head toward the base of leaf. About one quarter of the unchanged 
and feeding larva} in sight are dark colored. I find a few pupa} from which moths 
have already disclosed. Very young larva} and eggs are also common, as well as every 
intermediate stage. I have seen very few moths anywhere, none at all among the 
" young cotton." There is, however, a corner of the field through which passes a 
ditch, along which the cotton plants are more widely separated, and grow low and 
spreading, giving dense shade close to the ground. Such plants evidently afford ac- 
ceptable lurking places foi the moths during the daytime. The first seen were found 
here, July 17, and I have since started a few whenever I have passed through this 
part of the field. I do not think the moths give these plants the preference in deposi- 
their eggs, and the worms are not more numerous here than elsewhere. The fol- 
lowing is a detailed examination of one such plant, selected for medium height, 
spread, and general development.
