a Junonia (of another species), and a Catopsilia, of which the last was 

 immediately eaten. I put in another Catopsilia, which the bird ate 

 after plucking on the wings. 



I then took out the two Junonias, Elymnias, P. aristolochise and 

 D. eucharis from the cage, as it was getting dark, and threw away the 

 last, which was very dry. 



November 20th. — I gave the King-crow, which was hungry, the two 

 Junonias, the Elymnias (with its wings closed, as indeed before) and a 

 Danais chrysippus. One Junonia was soon taken, but the bird, after 

 tearing off a bit of wing, rejected the insect, possibly because it was 

 dry. But soon after all I had put in were gone. I then put in two 

 Gatopsilias and two Delias eucharis ; the former were eaten immediately, 

 the latter not touched. I then gave the bird a Papilio demoleus, which 

 it took, and pecked at the wings, and the insect soon disappeared, though 

 I did not see it swallowed. I then put in the P. aristolochise which I 

 had taken out the previous night, with a non-mimetic P. polites. Before 

 long I saw the bird pluck off the wings of the P. polites and eat it. 

 The two Delias eucharis and the P. aristolochise were still untouched. I 

 then put in a P. demoleus, and a Danais chrysippus and genutia ; almost 

 immediately the bird plucked the wings from the Papilio and ate it, and 

 soon after did the same with the D. genutia. Soon after this maggots 

 were given to the bird. Some time after these and the D. chrysippus 

 were gone, while the two D. eucharis and the P. aristolochise were 

 left ; and long after this, in the evening, these butterflies still remained, 

 though one Delias was minus the head and one hind-wing, and the other 

 also torn. A locust given to the bird had disappeared. I then put in 

 three P. polites, two of the mimetic, and one of the non-mimetic form, 

 and also a P. demoleus. This last, which was not put in quite simul- 

 taneously with the others, was almost immediately seized by the bird, 

 which a little after, took and ate in my sight the non-mimetic P. polites. 

 I then put another P. aristolochise in the cage. Then I saw the bird 

 pick up one of the remaining P. polites by the wing and drop it. I put 

 in a Catopsilia, and a locust ; the bird took the butterfly. Later, at 

 dusk, I saw it eating the locust. 



I afterwards took out the two P. polites and the fresh P. aristo- 

 lochise. 



November 21st. — In the morning, the bird being hungry, I put in the 

 two mimetic Papilio polites, with a Danais limniace and chrysippus. 

 The D. limniace was immediately taken and eaten. 



Soon after I took out the two Delias eucharis and the one Papilio 

 aristolochise, which had remained in the cage all yesterday, and up to now, 

 and threw them away, putting in instead the second P. aristolochise which
