once flung away, and after that the bird obstinately refused to have anything to 

 do with it. She then refused but, on my persisting, accepted, crushed, and 

 rejected an Ypthima, accepting it, however, when reoffered and swallowing it doubt- 

 fully. She afterwards shook her head. Neptis agatha was, however, accepted 

 eagerly and at once eaten. 



The bird now ate eagerly three smallish grasshoppers and another NejJtis agatha, 

 followed by a somewhat large grasshopper, and then refused Neptis agatha jDer- 

 sistently without tasting, readily ate Eurytela dryope, and again refused Neptis 

 agatha, but ate Eurytela hiarhas and after it two Neptis agatha. 



Ten minutes later she ate two grasshoppers, refused, but at once changing her 

 mind accepted and ate Neptis agatha, three more grasshoppers, then refused Neptis 

 agatha and Neptis saclava, but attracted by the latter's fluttering (the underside 

 only was shown in order to distinguish it from agatha) afterwards accepted, 

 crushed, and swallowed it. 



After three more small grasshoppers she readily ate a Neptis agatha, after three 

 more she refused to touch Neptis agatha but readily ate Eurytela dryope ; after 

 three more she again refused Neptis agatha but ate another dryope ; after two 

 more she once again refused Neptis agatha, tasted and rejected Eurytela dryope, 

 but on my reofFering it ate it but refused agatha. She now ate two more grass- 

 hoppers, and finally and persistently refused to touch Eurytela dryope or Papilio 

 echerioides § . 



A delay of five minutes now occurred, after which (by lamplight) Eurytela dryope 

 and Papilio echerioides 5 were once more refused, Char axes ethalion accepted and 

 readily eaten, Le%iceronia thalassina $ crushed and rejected, Papilio antheus $ 

 crushed very thoroughly and eaten, Papilio dardanus and Papilio de-modocus 

 persistently refused without tasting, Papilio lyceus well crushed and rejected, but 

 Caprona pillaana and a brown Crenis crashed and readily eaten. The bird now 

 refused to touch Papilio echerioides, Hamanumida dcBdalus, Precis cehrene, Catopsilia 

 florella, and Pyrameis cardui, simply settling down determinedly for the night. 

 This refusal was repeated twenty minutes later.

The Crenis was eaten (possibly under stimulation from the Caprona) up to 

 cehrene-vefvi&ixig point. I have placed P. lyceus and P. antheus over their two 

 pleasanter congeners here simply on manner. The difference is probably slight.
