and occasionally crushed before being finally swallowed, and the bird treated in the 

 same way a Mycalesis campina and a Papilio angolanus. She then most obstinately 

 refused to touch a M. campina, shook her head four or five times on being shown a 

 Teracolus phlegyas, but nevertheless accepted, crushed slightly and swallowed it, 

 again persistently refused to touch a Mycalesis, finally tasting it slightly and 

 i-ejecting it, refused an U. eriphia, then barely closed her bill on an antenna and 

 withdrew, refused with equal obstinacy a F. angolanus, refused in turn for a second 

 or two, but changing her mind accepted and crushed and swallowed a C. florella, 

 a Teracolus phlegyas, and an H. eri^^hia, again most obstinately refused Mycalesis 

 and P. angolamos, but readily accepted a Catopsilia florella. The butterfly was seized 

 only by a hindwing and on the bill cutting through this escaped and, finding an 

 opening in the wire of the cage, flew away. The bird then accepted a G. cloanthe 

 with actual eagerness and at once swallowed it wings and all. Most of the butter- 

 flies in this experiment were offered with wings. She then persistently refused to 

 touch any sort of grasshoppers, P. angolanus or M. campina, readily ate two of the 

 termite-nest grubs disliked by the warblers, crushed well and rejected P. lyceus, 

 refused without tasting a Lycaenid with two wings attached and a Spindasis 

 natalensis. 



Five minutes later she readily ate a dead but fairly supple H. eriphia, but refused 

 without tasting the P. lyceus. ^ 



Twenty minutes later she readily ate the Lycsenid, but went on to eat also a 

 Mycalesis campina and a P. angolanus.

Exp. 132. — January 8. Tasted and rejected a Zonocerus elegans $ , refused per- 

 sistently to have anything to do with Nychitona medusa, tasted and doubtfully 

 rejected a Mylothris yulei, crushed and threw away Olapa nitda, crushed and 

 readily ate a Terias senegalensis, refused a saw-fly larva that is destroying the 

 turnips, then tasted it with evident suspicion and threw it away. Its habits are 

 quite conspicuous and its coloration, though very dull, is in contrast to the 

 leaves it feeds on. 



A little later after feeding on grasshoppers she accepted and ate four Mycalesis 

 campina with two or three grasshoppers between each, the last two Mycalesis 

 after at first refusing them. She then held a grasshopper for some time in her 

 bill, crushing it occasionally, and finally threw it away, refused all others per- 

 sistently without tasting, as also a Myccdesis cam2nna and a P. angolanus, crushed 

 and readily ate an E. hiarhas, again refused P. angolanus and accepted, but after 

 crushing it threw away an E. hiarhas, eating, however, a C. florella,
