THE COTTOlSr-BOLL CrTWORM. 



43 



The first larva taken on March 80 was full o-rown, and was feeding- 

 upon ainiyj? quarter {Chenopodlum alhnin). All the others were taken 

 on cotton. No egg's were secured from reared moths, hut two lots 

 were found in the field. The brown, globular eggs were deposited 

 upon the under side of a cotton leaf, in a pile of about 200 or more. 

 They are laid in rows in a nearly' square mass, fifteen to twenty eggs 

 in a row and about fifteen rows. The mass is covered with light- brown 

 down from the female, which hides the eggs from view. 



Of several larvte pupating December 17, one adult emerged January 

 5, the remainder dying- in the pupal stage. 



Owing to the very complete description and account of this species 

 given ]>y Doctor Chittenden'^' it is unnecessary to enter into further 

 discussion concerning- it except to indicate its life history.

In addition to the records published by Doctor Chittenden, the 

 following notes in the records of the Bureau of Entomology upon 

 Prodenia flavimedin, which is now considered s3'nonvmous with this 

 species, are of interest. September 13, 1878, a larva sent b}^ C. V. 

 Kiley was received from Albany, Ga. October=5, 1878, another larva 

 was received from Professor Riley, probably' from the same locality. 

 This specimen commenced to pupate October 8 and the moth emerged 

 December 27. May 1, 1882, a larva was received from E. H. Ander- 

 son, who stated that he had observed the species feeding on cotton 

 at Kiikwood, Miss., for several weeks. This larva pupated Ma}' 8 

 and the moth emerged June 5.
