willful female in less than two hours. This continued 

 until the forenoon of the next day, Sept. 1, and at 6 that 

 evening she ate him. A new one was thrust in with her 

 immediately, and before 9:30 she had accepted him as 

 a mate. By the next morning they had separated. 

 Copulation was repeated that night, Sept. 2, and again 

 all day on the 4th. After this each went its own way, 

 until the morning of the 7th revealed an explanation for 

 this conduct during the past three days in the form of a 

 newdy-made egg-case. After this, copulation was 

 promptly resumed early the next morning, but by 8:30 

 A. M. the male, already headless, was being slowly and 

 calmly devoured by his mate, while he clung, apparently 

 automatically, without the least effort of resistance. At 

 2 P. M. the leisure meal was still in progress and by 4 

 o 'clock the entire body, excepting a wing, had been eaten. 

 No other mates could be gotten, so henceforth her life 

 was spent alone in the cage, until her natural death 

 Oct. 10. During her entire life after her capture, 56 

 days in all, she took very little food, excepting occasion- 

 ally a mate, and for the eight days preceding her death 

 she ate nothing whatever. 



Experiment 5. Aug. 15. A male and two females, a 

 gray and a green, were placed in a cage. Mating soon 

 took place with the green one. At 6 the next morning 

 they had severed, but they reunited at noon and con- 

 tinued so until some time during the night. At 3:30 

 P. M. of the following day, Aug. 18, this male turned his 

 attentions to the gray female. Mating continued 

 throughout the evening, but early the next morning only 

 her gray wings were to be found on the floor of the cage ; 

 evidently she had been devoured by her rival, for the 

 adult males never attack members of either sex. The re- 

 maining pair were indifferent to each other, so on Aug. 

 20 a new gray female was introduced. The next morning 

 however the male was found to have returned to his old 

 green mate, but at 2 P. M. they separated. No activities 

 whatever took place until the 23d, when the green female
