The crafty tree-hopper [Diedrocephala versuta Say) is widely dis- 
tributed throughout the United States and has many food-plants. I 
found it very common on cotton in Mississippi, its preference being for 
the terminal sprouts and tender, newly-formed leaves. Although quite 
numerous no serious injury seemed to follow its punctures. • 
The irrorated sharpshooter (Aulacizes irrorata Fabr.). Frequently 
found associated with Homalodisca eoagulata, which it somewhat 
resembles in appearance and in its habits. 
The garnished jassid (Phh-psius excultus UhL) is common all over the 
South, and its natural food plant is evidently some native grass. It 
was only occasionally observed on cotton. 
The half-clothed jassid {Eutettix seminudus Say) was often taken on 
the stalk of the cotton, and was observed to feed upon the juices of the 
plant. It is an omnivorous feeder, and will probably never become so 
numerous on any one plant as to be considered a serious pest. 
In addition to the above, I took feeding on cotton, Cicadula 4-Uneata 
Forbes, C. 6 punctata Fabr., and Ghloroneura sp. 
The cotton aphis {Aphis gossypii Glover) was exceedingly common, 
but was prevented from increasing too rapidly by its natural parasite, 
Lyslphlebus testaeeipes Cr., many of which were bred from it, aud by 
numerous predaceous insects belongiug to the families Coccinellida*, 
Chrysopida-, Hemerobiida-, and Syrphidse. 
The cotton Aleyrodes (A. gossypii Fitch). I see no valid reason for 
believing this insect anything else than the species described by Fitch 
under the name of Aspidiotus gossypii, he evidently having mistaken a 
dried pupa of an Aleyrodes, attached to a leaf of cotton, for a coccid 
belonging to the genus Aspidiotus. 
This species lives on the leaves, and toward the latter part of July 
and to the middle of August becomes exceedingly numerous, many 
hundreds occurring on a single plant, and when disturbed they fly up 
in powdery clouds. 
The eggs, from fifty to a hundred or more, are laid on the under side 
of a leaf, without any regard to order, resembling those of the orange 
Aleyrodes, only somewhat smaller, with a shorter pedicel, paler color, 
and with the surface perfectly smooth and shining. These hatch in 
from four to five days, and the young larvae attach themselves to the 
leaf and begin feeding on its juices. 
Although occurring by the thousands, I could detect but slight injury 
caused by these insects. 
ORDER LEPIDOPTERA. 
The most serious insect enemies to cotton are found in this order. 
Many insects belonging to other orders live and feed upon cotton, but 
as may be seen by these brief notes, these do not as a rule become 
serious pests, and while it is important that they should be destroyed 
whenever practicable, no apprehension should be felt on their appear- 
ing occasionally in the cotton fields.
