MISCELLANEOUS COTTON INSECTS. 
These records, with those published by Doctor Chittenden, would 
indicate the following as the probable life history of the species in the 
Gulf States. The winter is usualty passed in the pupal stage in the 
soil, though possibly a few moths, emerging late, hibernate. The first 
brood of moths appears from the middle of May until the middle of 
June, mostly early in June. A second brood appears during the latter 
half of July, and a third late in August and during September. A 
few of the fourth brood may emerge in December, but most of them 
do not do so until the very early spring, when they lay eggs upon 
various weeds on which the larvae feed until cotton appears. The 
length of time occupied in the different stages is seen to be quite varia 
ble, but is approximately 6 days for the egg, 20 days for the larva, 
and 13 days (usually 10 to 15 days) for the pupa — making a total of 
about 40 daj^s for the complete life cycle. 
A larva of Prodenia eridania Cress, taken on cotton at Terrell 
October 22, 1904, pupated November 1 and the moth emerged 
November 22. 
The caterpillars are parasitized by Ophion bilineatum Sa} T . 
THE COTTON LEAF-BUG. 
( Calocoris rapidus Say. Fig. 26. ) 
These capsids were noticed commonly upon cotton at College Station 
and elsewhere late in the summer of 1903, and a few were received for

identification, but little importance was then attached to them. Late 
in August, 1904, reports of serious injury to cotton were received from 
Kaufman, Hunt, Ellis, and adjoining counties, and Mr. Lewis was 
directed to investigate the injury. He reported as follows: 
On September 1 the insect was found abundant in all fields examined at Wolfe 
City, both nymphs and adults feeding upon the squares, young and half-grown bolls, 
and in the blossoms. The nymphs were most numerous on the squares, the adults
