MISCELLANEOUS COTTON INSECTS. 



These records, witli those published by Doctor Chittenden, would 

 indicate the following as the probable life history of the species in the 

 Gulf States. The winter is usuall}^ passed in the pupal stag-e in the 

 soil, though possibly a few" moths, emerging late, hil)ernate. 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, Init most of them 

 do not do so until the very early spring, when they lay eggs upon 

 various weeds on which the larvte 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 foi- the egg, 20 days for the larva, 

 and 13 daj^s (usually 10 to 15 days) for the pupa — making a total of 

 about 40 days for the complete life cycle.

THE COTTON LEAF-BUG.

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:
