11. Cut off the wings of tlucc male hoiia and gave 

 them to A, B, ami 0, but they were all rejected. Gave 

 one of the sauie specimens to D, which carried it off to 

 eat, and was still sucking it when observed two and a 

 half hours afterwards. 



12. Gave a wingless AuMitris echei'ia to A, which came 

 down very cautiously and bit it in the thorax as usual. 

 Its taste was evidently unpleasant, as in extricating the 

 buttertly I'rom the web it carefully abstained from biting 

 any part of the body. I then put the same specimen in 

 B's web ; she ran down at once and tackled it. After 

 giving it a few bites she paused as though in doubt, then, 

 as if thinking it was worth trying, she wrapped it up and 

 drew it up after her to her chamber. She was clearly still 

 doubtful, as she remained several minutes without attempt- 

 ing to touch it. She then sucked it for a few seconds, but 

 soon let it drop. Gave the same specimen to D, and it 

 was rejected. Gave another wingless specimen to C, 

 which also was rejected. 



13. Gave entire specimens of Terias hrigitta to B, C, 

 and D, and also female JSfcphcroiiia argia {agathina form) 

 to A. All were eaten readily. Subsequently gave entire 

 P. sesamus {natalcnsis form) to C, which was also eaten. 



14. Gave a perfect male Iwrta to D. She ran down, bit 

 it in the thorax as usual, wrapped it up and carried it off. 

 She then remained some minutes without attempting to 

 touch it, then after sucking it for a few seconds she threw 

 it away. (Compare Experiments 9 and 11.) 



15. Gave a wingless Arrxa violarum to spiders B, C, 

 and D, in succession. It was prom})tly ejected by each of 

 them. 



16. Gave entire specimens of A. lioria to spiders A, B, 

 C, and D. The two former ejected theirs at once; C cut 

 hers loose from the web, and was holding it in her jaws 

 preparatory to throwing it away, when she seemed sud- 

 denly to change her mind and ran up to her chamber with 

 it, without however enshrouding it with web. She 

 remained with it in her mouth for about half a minute, 

 and then threw it down. D took no notice whatever of 

 the insect in her web. 



17. Gave male Acnua liudoni to A, and female Ncplu- 

 Tonia argia {agathina form) to C. Both were eaten. 



18. Gave Pontia hcllica. to B, Painlio dcmodocus to C, and
