I then fed her on grasshoppers till she refused absolutely to touch another. Five 

 minutes later she ate two more, both very small, and refused most persistently to 

 accept another though I offered several species, but accepted, crushed, and very 

 readily ate Ate^'ica galene $ (one hindwing attached) and Hypolimnas wahlbergi 5 . 

 She then refused Papil'to angolamis without tasting, but on my continuing to 

 press it on her accepted, crushed, and at once rejected it. This was repeated 

 twice again, the roller being atti-acted back to it each time by the butterfly's violent 

 fluttering, but after that she refused persistently to taste it again, moving away 

 whenever I brought it near. 



Ten minutes later she for a minute or two refused to taste Pseudacrcea lucretia, 

 a black and white 2 with all wings attached, scrutinizing it closely and suspiciously 

 sometimes, but each time withdrawing without actually trying it. At last, however, 

 she accepted it, crushed it very thoroughly with a doubtful air and practically 

 swallowed it (in good position, head first and wings well back), but at once brought 

 it forward into the bill again and subjected it to a further tasting before finally 

 eating it. She then refused but on my continuing to hold it to her crushed and 

 rejected Papilio angolanus and refused a small grasshopper, but after a great deal 

 of persuasion ate the latter and two more, both very small, besides persistently 

 refusing to touch another, though as usual I oflfered several favourite species. She 

 then refused for a time but eventually tasted slightly and dropped a moth 

 [Goeuina ?), similarly refused but finally ate a 5 Arrugia basuta, and most 

 obstinately refused to touch either a second 5 Amogia basuta or a Precis cebrene, 

 being evidently quite replete. 



Ten minutes later she persistently refused the Coenina moth, readily ate an 

 Anomala itstidatipes and a 2 Arrugia basuta, refused for a few seconds but then 

 accepted and ate a second, I'eadily ate a c? Arrugia basuta and a Precis cebrene, 

 refused most obstinately to touch a Papilio angolanus, and refused for a time but 

 finally, changing her mind, ate an Anomala ustulatipes. Ten minutes later she 

 crushed rather doubtfully and ate a Ccenina moth and a Pi-ecis cebrene, but refused 

 a $ ^. basuta and a second Precis cebrene. 



[SuMMAKY : — (1) A^ote : " As I had no butterflies of the second class [Papilio lymus 

 or demodoGus) to otter, it is impossible to say that one of these would not have been 

 eaten at the moment at which I oflfered Aterica galene and Euralia wahlbergi. 

 The contrast between the I'elish with which these two butterflies were eaten and 

 the promptness with which Papilio angolanus was each time rejected would, 

 however, indicate that neither were less liked than Papilio lyceus would liave been, 

 for the gap between the latter butterfly and Papilio angolanus is not at present 

 great." \ - ■ 



(2) Probable order :— 



1. Aterica galene, 5 Anomala ustulatipes, &n^ ■pevh.a.^s, Arrugia 



basiota, Precis cebrene, and ffyj). ivahlbergi. 



2. The better grasshoppers, the moth, and P. angolanus, the 



moth being finally eaten with doubt up to cebrene refvisal- 

 point.
