Acrcea acara, biat only after much hesitation and tasting. 

 B, reassured, ate a second more eagerly. 



The experiment seemed to confirm certain previous con- 

 clusions — that B is more sensitive than A, and that the order 

 of " preference '^ is : (1) Acrcea, (2) Danaida, (3) Amauris. 



535. July 11. — Loplioceros leucomelas (not specified 

 whether A or B, but the former was, I think, at this time

 is doing well, and is readily accepting food from the forceps. 

 I carried out my first experiment on him this morning. It 

 was also the first occasion on which he has been offered
