62 Mr. C. F. M. Swymiertou on 



having taken the first, ate with apparent avidity an A. 

 lohengula and 3 A. albimacidata. Fifteen minutes later she 

 readily ate two A, lohemjula in succession. 



528. March 2. — B ate greedily an Amauris albimaculata. 

 Twenty minutes later she ate similarly 4 Amauris oclilea in 

 succession, but held an A. lohengula for a long time in the 

 point of her bill without an attempt to swallow it. She 

 ended bv handing it down to A, who swallowed it greedily. 

 Perhaps reassured by this she accepted an A. albimaculata 

 (same type of colouring) and swallowed it at once. 



Twenty minutes later she persistently refused without 



tasting another ^1. albimaculata, but greedily snatched a 



$ Acraa natalica from the forceps, and at once swallowed it. 



A meantime ate the A. lobenyula given him by B, then 

 ten A. natalica (5 c? (J and 5 ? ? ) in succession, and, at 

 intervals of two or three miuutes,[2 ? and 1 ^ A. acara and 

 a ? J., areca. 



I let twenty minutes elapse to allows for possible after- 

 effects from this large dose to make themselves felt, then 

 offered ^ ,$ A. areca (much the same colouring as the pre- 

 ceding butterflies). The bird at first refused it absolutely, 

 then, on my persisting in holding it to him, just closed the 

 point of his bill on it and at once, looking at myself, let go. 

 It is a common form of refusal amongst birds. He then 

 refused to take an Amauris albimaculata which I had been 

 offering B and, persistently, an Acrcea natalica $ . 



Fifteen minutes later, either recovering from the effects 

 or, if there were none, merely ready once more to digest 

 Acrseas, he ate readily enough after a little initial hesitation 

 an Acrcea natalica ? . B again refused without tasting an 

 Amauris lobengula. 



An hour and a half later A accepted and ate readily a ? 

 Acrcea natalica, and B, as readily, an Amauris lobengula. 



Two hours later again A ate no less than 23 large Acrreas, 

 all greedily and without the least sign of hesitation. They 

 were : 5 A. natalica ; ten minutes later five more ; ten later 

 five more ; ten later again 2 more. Twenty minutes later 

 again '6 (S A. acara, and ten later 2 S and 1 ^ A. areca.
