that I rather hesitated to experiment. However, I did so, 

 holding each insect in such a way that what light there was 

 might fall on it. 



The Hornbill refused to have anything to do with a 

 Belenois severina or a Mylothr'is yulei, but readily accepted 

 and ate a Precis elgiva ; refused a Terias Jirigitta (small 

 yellow Pieriue) and a Mylothris yidei, and accepted with, I 

 thought, a little hesitation, an Yptldma near imjjura. He 

 was probably nearly hungry enough for it, but he rejected it. 

 He refused a second Ypthima, as also a Henotesia perspicua 

 (another brown Satyrine) ; seemed doubtful over a Crenis 

 boisduvali, underside shown, but on my pressing it on him 

 accepted, crushed, and swallowed it; again refused Mylothris 

 yulei, also Leptosia medusa (one " wood ^'-white); accepted a 

 dead and dry Leuceronia argia, c?, and after crushing it 

 threw it away — probably the result of its dryness ; refused 

 for a time a white Catopsilia jflorella, perhaps taking it to be 

 the dry Leuceronia reoffered, then tried it, and at once 

 crushed and swallowed it. Then, to my surprise, took a piece 

 out of the wing of a Danaida clirysippus, and followed this 

 up by taking the butterfly from the forceps ; but on tasting it 

 he at once flung it right aw^y. Refused to touch an Amauris 

 dominicanus or again the Leptosia; readily accepted a Precis 

 clelia, but in turning it to crush it lost it; readily ate a 

 Precis tugela and a brown skipper Plalylesclies montili; 

 refused the Leptosia and a Mylothris yulei; accepted and 

 swallowed the Guinea-fowl-spotted Nymphaline Ilamanumida 

 dcedalus and a Precis elgiva ; refused to touch the Belenois 

 severina or an Yptldma near impura; but readily accepted, 

 crushed, and ate a small yellow-and-brown skipper, Padraona 

 zeno, a Rhopalocampta foi'estan, a Pyrameis cardid (Painted 

 Lady), another small skipper, Gegenes hottentota, and the 

 Precis clelia reoffered. He leaned out to take the Mylothris 

 yuleiy hitherto refused^ but I withdrew it; then descended, 

 picked up, and again tried and threw away the dry male 

 Leuceronia argia. 



The trial of the Danaida, and the bird^s apparent readiness 

 at the end to accept a Mylothris was curious, perhaps, for he
