one wing attached and swallowed it, once more tasted and rejected Papilio 

 angolamts and refused Papilio echerioides without tasting. 



Thirty minutes later (by lamplight) she tasted and rejected the wingless ango- 

 lanus S fi'iid a Eurytela dryope, also a second S angolanus with one wing, crushed 

 and readily ate Papilio lyceus $ , refused for some time, then tasted slightly and 

 at once rejected the Papilio echerioides 5 , wingless. 



Half an hour later she refused, then tasted and rejected Papilio echerioides, 

 crushed and rejected Eurytela dryope, crushed and readily ate Papilio angolanus S , 

 refused Papilio echerioides without tasting, crushed and rejected the next Papilio 

 angolanus S and a Eurytela dryope, but readily ate a Papilio lymus. She then 

 crushed and rejected both the Papilio angolanus and the Papilio echerioides, but 

 readily ate, after crushing it, yesterday's white Gatopsilia-\\kG butterfly, still quite 

 lively. 



[Summary : — 



1 . Papilio lyams 5 i Papilio demodocus $ , and the Catopsilia- 



like Pierine. 



2. Papilio a^igolanus S • 



{3. Eujrytela dryope, Eurytela hiarhas. 

 4. Neptis agatha. 

 5. Terias. 

 There was nothing to show whether the Papilio echerioides was more or less 

 disliked than the two species of Eurytela^ 



Exp. 75. — August 29. The bird refused a Terias, but on my continuing to hold 

 it to her tasted it very slightly, as though merely to humour me, and drew back 

 without tasting it. She then readily ate JSfeptis agatha and a migratory locust, 

 crushed and at once rejected Papilio angolanus with all its wings, readily ate

There was now a delay of, roughly, five minutes while I sallied out to catch a
