 before crushing and swallowing it ; played with Catacroptera cloantha and 

 Hamanumicla dcedalus, tossing them up into the air and catching them and finally 

 letting each drop, refused Precis cehrene, but, changing her mind, accepted it, held it 

 in her bill for a time and finally crushed and swallowed it, and refused without 

 tasting Jlamanumida dcedalus, Catacroptera cloantha, and Precis cehrene. Five 

 minutes later she refused to touch a ? termite or any grasshoppers, but accepted 

 and ate Catacroptera cloantha, Hamanumida dcedalits, Precis cehrene, and Catopsilia 

 florella, holding each for some time before swallowing it; refused, then tossed up 

 into the air a S Arrugia hasuta, a Precis artaxia, Precis natalensis © f., and 

 Precis cehrene. Five minutes later again and once more ten minutes after that she 

 refused to taste any of them nor would she touch a $ termite nor any of the 

 various grasshoppers ofiered her.

Exp. 94. — October 13. After a number of grasshoppers the bird readily ate 

 Papilio angolanus, four more grasshoppers, Papilio lyceus, and Charaxes hrutus, then 

 refused obstinately to touch a second Papilio lyceus or Pcipilio leonidas (with one 

 forewing attached to distinguish it more clearly from Papilio angolcmus which had 

 had a hindwing). Five minutes later she crushed and rejected Papilio leonidas, 

 readily ate a Precis artaxia,, and crushed and rejected Papilio lyceus, thus placing 

 Papilio leonidas below Precis artaxia, P. lyceus not above it, and P. leonidas and 

 P. lyceus each probably not above C. hrutus. 



Exp. 95. — Octoher 14. Readily ate in the morning several grasshoppers and a 

 Mycalesis campina, crushed thoroughly (with distinct difficulty at first in retaining 

 her grip on it owing to the hard polished surface of its elytra) and ate without 

 sio-n of dislike a black and white Cetoniid, then several more grasshoppers 

 and a Myccdesis campina. I then fed her on grasshoppers, crickets, etc., till she 

 absolutely and persistently refused to touch another, though I passed several 

 very favourite species in review before her. 



She then refused without tasting Papilio angolanus, tasted and rejected Papilio 

 leonidas, and, but with apparent disinclination, a Papilio lyceics, refused, then 

 tasted and flung right away the Papilio angolanus and once more tasted, this time 

 slio-htly, and threw aside the Papilio leonidas. Five minutes later she crushed and 

 once more rejected the Papilio leonidas and persistently refused even to taste 

 Papilio angolambs. Fifteen minutes later she crushed and rejected each. Ten 

 minutes later again she once more crushed and rejected each. Twenty minutes
