As is shown in Table I, the time of emerging of all moths varied 

 from May 9 to July 12. The greatest number of moths to emerge 

 on any one day was 16, and these individuals issued on June 19. 

 There was no marked period when the vast majority of adults came 

 forth, as is sometimes the case with certain species. A summary of 

 Table I shows that 45 emerged from May 9 to 31, 78 from June 1 to 15, 

 and 104 from June 16 to 30, making in all for June a total of 182; 

 and 42 from July 1 to 12. Most of the moths issued during the 

 month of June, and somewhat the greater number during the latter 

 half of the month. In pecan orchards moths were not commonly 

 seen until the early part of June, and by the middle of July they 

 were rarely observed; but belated individuals were met until the last 

 days of July. 



Rearing cages to determine the emergence of moths during 1914 

 were examined daily, except on June 7, 14, 16, 21, 28, July 5, 12, 19, 

 26, and August 2. The dates of issuance of 385 individuals are 

 shown in Table II.
