May 15 and 20. Cordley states 

 that in Oregon in ISOO moths 

 emerged in some cases April 

 10, and continued to do so until 

 July 1. At Ithaca, N. Y., 

 Slingerland found in 18! KJ that 

 moths emerged from May 3 to 

 June 22, and in lS97from May 

 24 to June 7. Gillette records 

 that he found moths out of 

 doors at Fort Collins as early as 

 April 20. The extreme range 

 in time of appearance of these 

 moths was 09 days in their 

 cages. At Fort Collins, ac-

 49 days in 1896.
