habit of feeding on forms or young bolls until about half grown, when 
they often migrate to the leaves, fold a portion of them together, and 
feed under cover. Many, however, remain with the young bolls, and 
reach maturity by feeding on them. They have been observed to bore 
half grown bolls and destroy their contents. 
CACCECIA ROSACE ANA. 
This Tortrieid attacks the cotton in much the same way as the pre- 
ceding species, and for that reason its depredations may- be mistaken 
for traces of the Boll Worm. The worm differs from the preceding in 
that the head, dorsal surface of the first segment, and the legs are black. 
PRODENIA LLNEATELLA. 
This fleshy worm was observed entering into nearly grown bolls and 
feeding on their contents. Its ravages are exactly like those of a nearly 
grown Boll Worm, and the two can not be distinguished. 
nocttjid (undetermined). 
A cutworm, lookiug much like Agrotis c-nigrum, was found in a large 
breeding cage which had been placed over some cotton plants in the 
field. When placed over the plants, none of the forms or bolls had been 
injured, and no Boll Worms were found on the plants. Some time later 
several large bolls had been bored, and this worm was the only one 
which could be found in the cage. The evidence is therefore only cir- 
cumstantial. 
PLANT LICE. 
(Aphis gossypii and Aphis sp.) 
These small, greenish, mostly wingless, insects were especially abun 
dant during the past season. Earlier in the season they are found prin- 
cipally on the leaves and younger growing portions of the branches, 
but frequently also on the young bolls between them and the involucre. 
Later in the season they are found most abundantly in the last-named 
localities, and in such great numbers on a single form or young boll 
that the latter soon fall off as a result of their puucturiugs. 
In many cases the fruit thus injured sitnply dries and adheres to the 
branch. This fact often serves to distinguish it from Boll Worm work. 
Even wdien this is not the case their work is readily distinguished in 
that the form or square contains numerous small punctures. 
THRIPID^E. 
These small brownish insects during August were found in great 
numbers in the forming blossoms of the cotton plant. The feeding of 
these insects causes the form to drop soon after the blossom falls, if
