6 MISCELLANEOUS COTTON INSECTS. 
It may not be out of place here to briefly refer to previous articles 
on cotton insects. Having briefly mentioned a few species during- the 
preceding year, in 1855 Townend Glover included an article on cotton 
insects in his report to the Commissioner of Patents for that year, 
illustrated with numerous figures of the more common species. a Later 
he engraved better figures of many of these species, with which he 
published a few notes. 6 
In 1892 F. W, Mally, at that time an assistant in the Division of 
Entomology, in his report on the bollworm/ mentioned several cotton 
insects whose injuries might be mistaken for those of the bollworm. 
Some portions of this report were republished in Insect Life. As a 
result of an investigation of the insects frequenting cotton fields in 
Mississippi, Dr. William H. Ashmead published several papers d in 
which he gives brief notes on the habits of the insects found. In 1896 
Dr. L. O. Howard gave the first general account of cotton insects 
published since that of Glover/ Since the publication of this paper 
no general study has been made of cotton insects other than the boll 
weevil and bollworm, except that excellent work of Prof. H. A. 
Morgan upon the differential locust, which is noted in the account of 
that insect in the following pages. 
From his study of the life histories of the minor cotton insects and 
the methods of cotton culture, the writer believes that for but few of 
them will artificial remedies, such as poisoning, be found generally 
practicable. Like most of the insects affecting our staple crops, they 
must be largely controlled by general methods of culture and farm 
management, such as the destruction of their native food plants, rota- 
tion of crops, and winter or early spring plowing. More intensive 
cultivation of cotton will undoubtedly result in a material lessening of 
the injury Try many of these pests, and, under such conditions, those 
which may be profitably combated by remedial treatments will be 
more successfully and generally treated. 
Most of the work upon the life histories described below was done 
by Mr. A. C. Lewis, who was in charge of a temporaiy laboratory 
upon the demonstration farm of Mr. E. H. R. Green, at Terrell, 
Tex., and by Mr. C. E. Sanborn at the laboratory at College Station. 
Mr. A. F. Conradi, at that time assistant entomologist of Texas, also 
helped in the work. The writer is indebted to Doctor Ashmead, of
