658 F. Finn — Experiments with various Birds. [No. 4, 



the bird preferring to attack both the Danais and the Delias. Some 

 time after, (maggots having meanwhile been given) the P. demoleus 

 had evidently been eaten and the D. genutia was gone. I pnt in two 

 P. demoleus and another D. genutia ; the latter was attacked. Not long 

 after the two P. demoleus had been pecked to pieces, and mostly eaten ; 

 the wings of the D. genutia had been pecked, bnt the body was intact ; 

 the Delias eucharis, which I had noticed as having been pecked when I 

 put in this last lot, wasalso intact, all but the head. But some time later 

 both the Danais and Delias had apparently been treated like the 

 P. demoleus. 



December 6th. — In the morning I gave the Shama a non-mimetic 

 Papilio polites and a male Nepheronia hippia ; the latter was attacked 

 first, and both were apparently eaten, as I could not find them later. 



December 1th. — I gave the Shama, which was not hungry and had 

 had insects given it, a Huphina phryne, a Delias eucharis t and two small 

 Catopsilias. Some time after all had evidently been eaten ; I did not 

 see which had been taken first. 



I then put in one D. eucharis, one D. chrysippus, one Catopsilia, 

 and three Junonias. Not long after I found that all had been 

 eaten except D. eucharis and D. chrysippus, the former of which was 

 minus its head. While these were left I put in two Papilio demoleus 

 and two D. genutia. Soon after one of the latter had disappeared, 

 leaving no trace. The others remained for some time with the butter- 

 flies previously left, but at night the other D. genutia had evidently been 

 eaten, and the wings of the D. chrysippus had been picked off. But its 

 body was left, as also were the D, eucharis and one P. demoleus. 



December 8th. — The butterflies left last night were still in the cage 

 this morning, almost all of the wings of the P. demoleus having been 

 picked off. I put in a non-mimetic P. polites, and soon found that it had 

 been pecked to pieces and the body was gone. I then took out the others. 

 Even most of the wings of the P. polites seemed later to have been eaten. 

 I put in, before the bird had yet had any insects, a P. demoleus ; some 

 little time after I found this also with its wings pecked, but not eaten. 

 I took out the bird and put it into another cage. 



December 9th. — I put into the cage of the Shama, in the morning, 

 when it had insects, a male Elymnias undularis. A little later the 

 bird had evidently eaten this. 



I then put in the cage a non-mimetic Papilio polites, and two P. aristo- 

 lochise. Looking afterwards, I found the bird had apparently eaten 

 one P. aristolochise, a small specimen, the other and the P. polites being 

 left. Afterwards I saw the bird attacking the latter, and later found 

 it had eaten both. Some time afterwards I found the head of the 

 P. aribtolochise.
