320 Mr. G. A. K. Marshall on 



The spiders experimented on were all of one species 

 with very large females and minute males. Their Avebs 

 were all round the verandah, where they were strictly 

 preserved by Mr. Ball. I never saw the species in the 

 bush. 



1. Gave a spider (A) a specimen of Acriea liorta 

 (entire) ; she ran down and bit the thorax, then pulled it 

 out of the web and dropped it. At the same time gave 

 A. liorta with its wings cut off to another spider (C)of the 

 same species, which ate it without hesitation. 



2. Gave liorta without wings to four spiders (A, B, D, 

 and E), and also one in which half the wings had been 

 cut off to C. All were eaten readily. 



3. Gave entire males of liorta to A and B, and both 

 were at once rejected. 



4. Wingless specimens of L. clirysi'ppiis given to A and 

 C were at once thrown out of their webs. 



5. The following wingless specimens were given to this 

 species : — Fajnlio brasidas to A, P. opliidiccplialus to B, 

 P. euplira^ior to C, P. opliidiceplialus to D, Eurytda hiarhas 

 to E, and P. lymus to F. All of them were promptly 

 eaten. 



6. Caught a female liorta, rubbed all the colour off its 

 wings, leaving them entire, and gave it to A, which after 

 careful examination wrapped it up and carried it off" to eat. 



7. Gave A a perfect male liorta; she ran down and bit 

 it in the thorax and ejected it from the web. I then 

 rubbed all the colour off the wings and returned it. The 

 spider approached it carefully feeling round with her palpi, 

 and again cut the butterfly loose. I then gave it to B, 

 which also refused it. I then cut the wings off and gave 

 it to B again, with the same result. Finally I gave it to 

 A again, but she pulled it out of the web by the abdomen 

 and dropped it. 



8. Gave wingless specimens of Papilio dcmodocus to B 

 and C. Botli were eaten. 



9. Gave a perfect female liorta to D, which bit it several 

 times, being seemingly rather doubtful about it, but 

 eventually wrapped it up and carried it off to her chamber. 

 After a short time she threw it down, the butterfly being 

 still alive. 



10. On two occasions saw dead specimens of A. liorta in 

 spiders' webs in the bush. They were both wrapped up, 

 but evidently had not been sucked.
