tasting Leuceronia argia, Papilio dardanus J , and Eurytela dryope, but crushed 

 and readily ate a Charaxes neanthes, a Melanitis leda, and a Rhopalocampta libeon 

 (no smell), also a Charaxes vologeses, tlie latter after a little delay, the bird being 

 no longer hungry. She then merely played with Charaxes pollux, repeatedly tossing 

 it up and catching it again and ended by dropping it, afterwards refusing Pyrameis 

 cardui and Precis cehrene. 



Ten minutes later she crushed and tossed away a 5 Leuceronia argia, crushed 

 similarly and threw right away a Papilio dardanus S , and accepted the previously- 

 offered Charaxes pollux and a Melanitis leda, playing with each for a few seconds 

 before finally swallowing it. She then refused without tasting, but on its being 

 reoffered accepted, crushed, and tossed aside a Rhopalocainptaliheon (no smell) and 

 refused without tasting Eiirytela dryope, Byhlia (the dark individual previously 

 rejected), Pyrameis carditi, and Precis cehrene. 



Five minutes later she tasted and rejected Papilio dardanus 6 , readily ate a 

 Pyrameis cardui, tasted well and rejected a light-coloured Byhlia, crushed and readily 

 ate a Hamamimida dcedalus and a Mela.nitis leda, tasted and rejected a (forest ?) 

 Mycalesis campina, also Henotesia, tasted and readily ate Precis cehrene. Precis 

 elgiva, and two Charaxes neanthes, then played with and finally swallowed a 

 Charaxes achcemenes. 



I was here interrupted for some minutes. On my return I offered Precis 

 natalensis f., which was readily eaten, but the bird had evidently become 

 hungrier, for she now crushed and at once swallowed the Leuceronia argia $ 

 already rejected and a Papilio lyceus. 



I now gave her two Charaxes hrutus, after which she refused without tasting a 

 Leuceronia thalassina $ , tasted and rejected JSfeptis agatha, but accepted, crushed 

 well, and swallowed a Rhopalocarapta libeon with a slight Pentatomid-like smell. 



[Summary : — Placing in Grade 1 not only the species for which a special preference 

 as against the next grade was shown but also those eaten or dallied with close to 

 apparent repletion-point, we have : — 



1. R. libeon, C. vologeses, C. pollux, M. leda, C. neanthes, C. achcemenes, 



P. clelia, P. archesia, P. cehrene (perhaps P. natalensis, I', cardui, 

 H. dcedalus).

2. Leuceronia arqta and thalassina. „ , 



'' yL. dryofe, 



3. Terias, N. saclava, M. campina, and probably Byhlia. ^ , 



P. lyoius, H. perspictia, and P. elgiva might all be inserted above Grade 3 were 

 it not for the possibility that they were eaten after special stimulation.]
