1. M. agathina S and N. leuconoe. 



2. A. asema.'] 



Exp. 43. — Jime 15. Yery hungry after unusually long period without food; 

 refused persistently without tasting Danaida chrysippus, Acrcea serena, Acrcea 

 douhledayi, and Acrcea caldarena. A testimony to the low grade of these 

 butterflies. 



Exp. 44. — June 17. Yery hungry, several hours without food; refused without 

 tasting Acrcea asema. A testimony to the butterfly's low grade. 



Exp. 45. — June 19. Slightly hungry, readily ate a migratory locust, refused 

 persistently without tasting a Terias, readily accepted and ate a Neptis cogatha, 

 tasted and rejected but, on its being reoflfered, ate an Ypthima and after it, 

 without eagerness but without special hesitation, a second. 



I then gave her one large and four small grasshoppers, equivalent in all to, 

 perhaps, four large Charaxes. They were slowly eaten, the bird being evidently 

 no longer hungry. 



She then tasted and rejected Pajnlio dardanus S , tossing it away, refused 

 without tasting Papilio dcirdanus $ f. hippocoon, accepted, played with, and 

 dropped Charaxes achcemenes, but crushed and ate it readily enough on my now 

 reoffering it ; tasted very thoroughly and then readily swallowed the pupa of 

 Pyrameis cardui, pupated May 27 ; refused without tasting a rather dark Byhlia 

 and Precis ncUcdensis © f., then accepted and ate, though without special appetite, 

 Pyrameis cardui and Precis cehrene, crushed very thoroughly and tossed aside 

 Precis ncttalensis f., crushed and readily ate Precis clelia, tasted slightly and 

 rejected Lctrnpides bcetica. 



Five minutes later she again tasted and dropped Precis natalensis © f. 



Five minutes later again she crushed it well and swallowed it with no sio-n of 

 dislike, refused obstinately without tasting Lampides bcetica, Ypthwna, and Papilio 

 dardanus S , but readily ate a Precis cehrene.
