MISCELLANEOUS COTTON" INSECTS. 
These eggs hatched July 23, but the nymphs subsequently died. This 
observation clearly indicates that oviposition sometimes, if not alwa} T s, 
takes place in July/' During July and August nymphs are commonly 
captured by sweeping, though the first generation matured in June. 
The fall eggs are not laid until October or November, and during 
September fresh adults are found. 
The oviposition on cotton is of no practical 
importance, and the crickets doubtless do much 
unnoticed good in consuming the plant lice always 
abundant. 
STALK-BORERS. 
AMPHICERUS sp. 
Early in March, 1904, Mr. J. W. Howell, of Cor- 
sicana, Tex., sent cotton stalks containing speci- 
mens of a species of Amphicerus. Upon visiting 
this field as many as a dozen of these beetles were 
often found in a stalk. No injury could be attrib- 
uted to them, and it seems probable that they 
work merely in the mature stalk and hibernate in 
it. The species may be the same as that observed 
at San Diego, Tex., by Mr. E. A. Schwarz, who 
took specimens of Amphicerus fortis Lee. in old 
cotton stalks April 25, 1895. 
ATAXIA CRYPTA Say. 
This species has been styled the cotton stalk- 
borer. It can hardly be considered a cotton insect, 
however, as it attacks only diseased or injured 
stalks, and normally breeds in cockle. It has not 
been recorded as injuring cotton except individual 
stalks here and there. The records of the Bureau 
of Entomology state that a larva of this species 
which had been boring into the root of Xanthium strumarium was for- 
warded by Mr. Schwarz from Beeville, Tex., October 26, 1895. One 
beetle issued June 24, another July 3, two July 27, and one July 29, 
1896. May 1, 1897, a beetle was reared from a stem of cockle from 
Tucson, Ariz., three more emerging June 8.

« June 23, 1905. Mr. Sanborn states that the species has been full grown for at 
least five weeks and has been ovipositing. He thinks that there are undoubtedly 
two broods.
