EXPLANATION OF FORM AND COLOURING. 295 



Fifteen minutes later she refused but, changing her mind, ate Papilio angolanus, 

 refused similarly and then ate a Terias, then (this time readily enough) ate another 

 Terias and a second Papilio angolanus, two small grasshoppei's, and yet another 

 Papilio angolanus. I had, unfortunately, no Terias left to offer, but the experi- 

 ment up to this point convinced me sufficiently that the bird regarded Papilio 

 angolanus as on about the same level as Terias. 



She then ate seven small grasshoppers, refused, then twice crvished and rejected 

 iVeptis agatha, tasted and rejected, but then changing her mind ate Eurytela 

 dryope and, with apparent relish, after crushing it, Papilio antheus. 



An interruption of twenty minutes now occurred. On my return the bird 

 readily ate seven small grasshoppers and a Nep>tis agatha, a small and a large grass- 

 hopper, and another Neptis agatha. After seven more small grasshoppers, however, 

 she refused obstinately and repeatedly to touch JVeptis agatha or Eurytela dryope, 

 crushed well and rejected Papilio lyceus, crushed and readily ate Papilio antheus, 

 crushed and rejected, but on my reoffering it ate Papilio lyceus, listlessly, however, 

 as though quite disinclined for food, refused the next without tasting, but, finally, 

 yielding to my importunity, tasted and rejected it; obstinately refused Papilio 

 demodocus, refused, then crushed and rejected Papilio da7-danus (S , and obstinately 

 refused to touch either Papilio antheus or Papilio lyceus. 



Five minutes later she refused to touch Papilio lyceths, Papilio demodocus, Paptilio 

 antheus, and Papilio dardanus S , but readily accepted and ate a Catopsilia Jiorella, 

 afterwards, her appetite doubtless stimulated by the eating of the Pier'ine, accepting 

 and eating Papilio lyceus after much crushing and with evident disinclination. 

 She then crushed slightly and tossed carelessly up into the air the S Papilio 

 dardanus, crashed veiy thoroughly and swallowed, though once more with dis- 

 inclination, the Papilio demodocus, and refused persistently to touch Papilio 

 antheus, Paj^ilio dardanus c? , Papilio lyceus, and Gatojysilia flo-) ella. 



Five minutes later she once more refused all four. 



Five minutes later she readily enough ate Catop>sili a Jiorella aiid Papilio antheus, 

 each as usual after crushing, refused, then accepted, crushed long and doubtfully, 

 and finally ate Papilio dardanus r? , refused obstinately to touch Papilio lyceus, 

 half-tasted and refused to take Papilio dardanus 6 , and once more persistently 

 refused without tasting Pa2nlio demodocus and Papilio lyceus. 



Three minutes later she crushed well and ate Leuceronia argia $ and refused 

 without tasting Papilio demodocus, Papilio lyceus, Leuceronia thalassina $ , and 

 Catopsilia Jiorella, but ate with disinclination one small grasshopper, refusing 

 utterly to touch a second. The first was held for quite a long time in the point 

 of the bill before being swallowed. 



She then refused, but changing her mind tasted and, reassured, at once crushed 

 well and swallowed Salamis anacardii, and after it, again after thorough crushing, 

 Papilio dardanus 5 f . hippocoon. She then crushed well and tossed away Papilio 

 antheus and persistently refused without tasting Salamis nehulosa, Salcimis ana- 

 cardii. Precis natalensisQ, Pyrameis cardui, Siwd Precis cehrene, ^nnWj, however, 

 changing her mind and eating the Precis cehrene and leaning forward to the 

 Pyram^eis, which I reoffered, but withdrawing without tasting it, evidently utterly 

 replete. A second Precis cehrene was now persistently refused without tasting.
