offered her at least eight comparatively pleasant species, readily ate an Antanartia 

 schceneia, an E. hiarhas, and a large Gh. candiope, tasted and rejected A. schceneia, 

 refused Precis natalensis Q without tasting, but finally crushed it slightly and rejected 

 it, ate after a momentary hesitation an U. hiarhas but would have nothing to do 

 with the next, tasted and rejected a Pap. demodocus with wings and without, after- 

 wards refusing it without tasting, and ate most readily after crushing it slightly a 

 S Aterica galene. She then persistently refused a Lachnoptera ayresi and a 

 P. natalensis f., but finally snatched each irritably from the forceps and gulped 

 it down without an attempt at tasting it, and, after further refusals, an Antanartia 

 schceneia. A Pap. demodocus was tasted more calmly and rejected, and a Pr. tugela 

 crushed and readily eaten, but a P. natalensis f. was taken and just tossed aside 

 and, on being reoft'ered, was snatched away and swallowed with an air of extreme 

 irritation as before ; also a P. ceryne (a rubbed specimen). Pap. demodocus was 

 taken from the forceps and rejected, a P. natalensis eaten but the next rejected, 

 and on re-presentation persistently refused. A.i\ Atella phalantha c? was similarly 

 swallowed and the next rejected, but finally gulped down, A P. natalensis f. 

 was refused persistently, as was an Atella with wings, but the latter was finally 

 accepted and swallowed and the P. demodocus once more taken and rejected. 

 Another Atella was knocked out of the forceps, then for a time refused and finally 

 snatched away and hurriedly gulped down. A Phrissura isokani was most 

 obstinately refused without tasting, an U. hiarhas after being for some time 

 ignored was snatched irritably from the forceps and swallowed, as was also a 

 Pr. natalensis f . ; and the Pap. demodocus was again taken and thrown Siwa.y. 

 The bird was in a thoroughly irritable mood, but there was no mistaking the change 

 when a Ch. hruttts with one wing came on the scene. She took it with distinct 

 eagerness and crushed and battered and swallowed it, obstinately refused to touch 

 the P. demodocus, then ate a small grasshopper readily enough, bvit obstinately 

 refused the next. 



[The order would seem to have been roughly as follows : — 



1. Aterica galene, Charaxes hrutus, Precis tttgela. 



2. Eurytela hiarhas, Antanartia schonneia, Atella phalantha, 



Precis natalensis f., and Precis ceryne,

I- 4. Mylothris yulei, Terias, and Neptunides polychrous. 



Probably there is not much to choose between Antanartia schceneia, Precis 

 nOitalensis f., Precis ceryne, and Atella phalantha, none of which butterflies were 

 at all acceptable in the actual state of the bird's appetite.] 



Exp. 157. — March 13. Fed on grasshoppers till she would eat no more, tasted 

 and rejected P. demodocus, but crushed and readily ate a Lachnop)tera ayresi ( $ ) 

 and a Salamis cacta, var. Ictngibida. 



Fifteen minutes later she crushed well and rejected a Reduviid bug, Harpactor 

 erythrocnema, readily ate a P. demodocus, threw away an Amiaidus globtolipennis
