Exp. 80. — September 2. Distinctly hungry, readily ate Mylothris agathina $ , 

 refused with many shakes of the head Nychitona medusa, tasted it and flung it away 

 on my pressing it on hei-, tasted and rejected Nyctemera leuconoe, refused without 

 tasting an Aletis monteironis, readily ate Mylothris rueppelli 5 , crushed thoroughly 

 and finally rejected with evident dislike a $ of the common blue-and-yellow 

 Ichneumon {Osprynchotus Jiavipes) that so often enters houses, crushed and after 

 hesitation ate Mylothris yulei 5 , accepted the Ichneumon doubtfullj^ and, 

 after subjecting it to very prolonged crushing, half swallowed it, again crushed 

 it thoroughly and ended by swallowing it finally, then crushed and rejected 

 Nyctemera leuconoe, Aletis monteironis $ , Syntomis cerbera, and Planema 

 aganice 5 . She now, after five small grasshoppers, refused obstinately to touch 

 Terias senegalensis, but readily ate a Papilio angolanus and a Belenois severina. 

 After seven more grasshoppers it again refused to accept the Terias, but after 

 ci-ushing it well ate a Papilo angolanus. Then followed a grasshopper and another 

 Papilio angolanus, a second grasshopper and again a Papilio angolanus, two more 

 grasshoppers and three separate rejections after tasting of Papilio angolamis. 

 Belenois severina was then refused persistently without tasting, a Neptis agatha 

 barely tasted and rejected, a Papilio angolanus (one of the rejected ones) crushed 

 rather doubtfully and eaten, a Neptis agatha refused, then definitely crushed and 

 rejected, a Belenois severina tasted well and rejected, then refused persistently ; 

 a Painlio angolanus tasted and rejected but eaten on being reoiFered and a Neptis 

 agatha refused without tasting, but then tasted well and rejected. The bird now 

 for a minute or two refused to touch Papilio echerioides J , then barely closed the 

 point of her bill on it and refused to take it, again refused it without tasting, and 

 finally accepted, crushed it well, and ate it without further hesitation. She then 

 refused Neptis agatha, but changing her mind accepted and ate it, refused a second, 

 but, once more changing her mind, ate it ; refused repeatedly and emphatically to 

 have anything to do with a Belenois severina, but readily ate a, Papilio angolanus.
