EXPLANATION OF FORM AND COLOUEING. 317 



Hypolimnas wahlhergi, readily ate a c? Arrugia hasuta, then, after refusing it 

 again, accepted, crushed well and rejected the Hypolimnas wahlbergi. 



Twenty minutes later by dim lantern light she crushed and readily swallowed 

 the Hypolimnas tvahlbergi, but rejected with every sign of disgust a Papilio 

 angolanus, also without wings.

2. P. angolanus and grasshoppers.

2. Hypolimnas wahlhergi (not worse, probably better, than 

 P. angolanus) J] 



Exp. 104. — November 13. Fed on grasshoppers till she persistently refused to 

 accept another (several favourite spp. were refused), she ate but with dis- 

 inclination a Papilio angolamts and refused to have anything to do with a second. 

 She then accepted eagerly enough, crushed slightly and nearly swallowed a large 

 Saturniid moth without wings, but brought it forward into her bill once more and 

 subjected it to a very prolonged tasting, evidently feeling quite doubtful about it, 

 before finally throwing it away. She then once more refused to taste Papilio 

 angolanus^ but accepted, crushed well, and swallowed with apparent relish a lar^e 

 Noctuid, Argadesa materna, with two wings attached to distinguish it from 

 the Saturniid. She then, evidently quite replete, refused persistently without 

 tasting a Precis cebrene, a d Arrugia hasuta, a Gatopsilia Jiorella, and a Charaxes 

 cithceron. 



Fifteen minutes later she refused Papilio angolanus, then barely closed her bill 

 on one of its antennae and withdrew with shakes of the head ; refused the 

 Saturniid moth and then, as in the case of the preceding offering, barely closed 

 her bill on it and withdrew with signs of dislike. She readily, however, ate the 

 Precis cehrene and the S Arrugia hasuta, but refused, then crushed well, and 

 rejected the Catopsilia Jiorella. It appeared just possible that she had in mind 

 other and distasteful white species and did not allow the evidence of her taste to 

 overcome her suspicions, for she now readily enough accepted and ate another 

 Arricgia hasuta ( $ ).

Exp. 105. — Noveinber 14. Refused, then tasted and rejected an Aletis mon- 

 teironis, persistently refused even to taste Mylothris yulei, but readily ate a 

 Mycalesis campina. She then ate three smallish grasshoppers and refused without 

 tasting, but, changing her mind, accepted and swallowed another Myc. campina. 

 She exactly repeated the performance in connection with each of five more 

 Myc. campina, ofiered as before at intervals of three grasshoppers. She then
