PHILOSAMIA CYNTHIA AND CALLOSAMIA 

 PROMETHIA CROSSES. 



By Louis H. Joutel, 

 New York, N. Y. 



It may be of interest to supplement Miss Soule's notes on cyntliia 

 and promethia * crosses with my experiences last summer when I was 

 so fortunate as to get some hybrid larvse that differed from both 

 parents. 



Having had crosses a number of times for several years between 

 Cynthia $ and promethia cf without being able, for some unknown 

 cause to raise the resulting larvse to maturity, I determined, as Mr. F. 

 E. vVatson was kind enough to again supply me with cocoons of both 

 species, to try this past summer what could be accomplished with care
