immediately the Sibia and a Liothrix had each taken one of the non- 

 warningly-coloured ones, and soon another Liothrix had a third, the 

 Catopsilia. I then saw the Sibia take another close by this insect, 

 which it swallowed whole, though as big as Pontia rapse. This bird then 

 took a third non-warningly-coloured butterfly, but a Liothrix took this 

 away after it had partly picked off the wings ; however, as I found what 

 appeared to be this specimen on the floor afterwards, I suppose the 

 Liothrix dropped it. 



In fact, the Liothrix now, being probably pampered, seem to be- 

 have with non-warningly-coloured insects much as the larger Babblers 

 used to do with Danaids. 



I think the Sibia finished up the last two non-warningly-coloured 

 butterflies, including one which had been apparently dropped. The 

 Euplcea and its mimic P. panope remained untouched. 



May 2nd. Early in the morning Euploea and P. panope were still 

 untouched by the birds, even before maggots were given. Later, after 

 the birds had received their ration of these insects, I found that the 

 P. panope had disappeared all but one wing, while even by evening the 

 Euplcea was untouched. 



There had been maggots and other food in the cage all day, and I 

 now put in three male Elymnias undularis, and one each of Papilio 

 eurypylus, P. panope, P. demoleus, Danais genutia, D. limniace, and Catop- 

 silia, all decapitated, and a live P. aristolochise. 



The Sibia first took an Elymnias, which the Mesia snatched ; the 

 former bird then ate the Catopsilia. Then it took another Elymnias, 

 but after pulling off part of the wings, dropped it and wiped its beak on 

 the perch. Then it took and dropped the P. eurypylus, wiping its beak 

 slightly. 



I think the Mesia ate the first Elymnias, 



A Liothrix then took the Elymnias which the Sibia had rejected 

 and ate it, apparently with no great relish. Both from the conduct of 

 this bird and that of the Sibia one might have thought the insect un- 

 palateable. 



The Sibia then took the third Elymnias, but soon dropped it, whole, 

 and wiped its beak. Yet it evidently wished for more butterflies. I 

 then saw the Mesia with this specimen. 



I next put in three non-warningly-coloured butterflies ; immediately 

 the Sibia seized one, and had torn off much of its wings, when a Liothrix 

 took it. However, the former bird soon took another, tore off its wings, 

 and apparently ate some. Meanwhile the HJlymnias taken by the Mesia 

 h?,d disappeared. 



The Sibia then ate the P. eurypylus, with some slight signs of 

 J. ii. 82
