In the family Coccinellidae Megilla maculata I)<-G.. Hippodamia eon- 
vergem Guer., Goeeinella 9-notata Hbst., and C. sanguined Linn, were 
common in all stages, feeding upon the cotton aphis (Aphis gossypii 
Glover). Chilocorus bivulnerus Mills., Exochomus marginipennis Lee., 
and Pentilia auralis Lec, were observed feeding on the cotton Aley- 
rodes (Aleyrodes gossypii Fitch), while two species of scymnids, Seym 
nus caudalis Lec. and 8. cervicalis Muls., fed on both the cotton aphis 
and the cotton Aleyrodes. 
The Pennsylvania fire-fly, Chauliognathus pennsylranicus DeG., and 
the yellow-margined fire-fly, C. marginatus Fab., were exceedingly 
abundant in the blossoms, with occasional specimens of Pyropyga 
minuta Lec. and Photinus marginellus Lec. 
All these insects are beneficial as pollenizers, and the larvae of the 
first two were frequently seen crawling over the ground beneath the 
cotton plants. In this stage they are said to feed on the cotton-worm 
and other lepidopterous larvae. 
In the Chrysomelidae I took the following species: Lema 6-punctata 
Oliv., Anomcea laticlavia Forst., GryptocepTialus calidus Suffr., Myochrous 
denticollis Say, Colaspidia flavida Say, Nodonota tristis Ol., Phyllech- 
thrus nigripennis Lec, Diabrotica 12-punctata OL. D. vittata Fab., and 
Systena elongata Fabr. Of these only three maybe mentioned as injur- 
ing the plant. Anoma a laticlavia feeds on the leaves, while Colaspidia 
flavida and Nodonota tristis gnaw little irregular holes through the outer 
covering of the blossoms, and frequently gnaw into the epidermis, of 
the bolls, thus exposing them to the weather and causing them to drop. 
The Diabroticas were captured in the blossoms feeding on pollen: they 
evidently breed in neighboring cornfields. 
One species of Brnchidae was common in cotton blossoms — the four- 
spotted bean-weevil (Bruchus 4-maculatus Fabr.). It would be inter- 
esting to know whether or not this species lives in cotton seed. 
The 8-spotted mordellid [Mordella 8 -punctata Fabr.) was often seen 
in the blossoms, but in the larval state it is said to live in the stems of 
various plants. 
Two species belonging to the family Anthicidae, Xotoxus Jncolor Say 
and Macratria murina Fabr., as well as some weevils belonging to the 
family Curculionidai, Apion sp., Paris sp., and Centrinus picumnus 
Fabr., and a Meloid, Epicauta strigosa Gyll., were common in cotton 
blossoms.
