Exp. 189. — February 27. Very hungry, readily ate an A. johnstoni and an 

 A. igola, refused without tasting A. caldarena. 



Exp. 190. — March 1. Kept longer than usual without food and very hungry, 

 readily ate after crushing it an A. igola, red 5 , tried and rejected A. caldarena and 

 a second A. igola( c? ), readily ate, after crushing it, an A. johnstoni, and refused, 

 then tasted slightly, and rejected the A. igola cS reoffered. 



After a full-grown larva of Khahdotis aulica she refused most emphatically and 

 persistently without tasting it A. esebria (a slightly buffy-white 2 )> J^ycteviera 

 leuconoe, A. lohengida, and A. alhimaculata. 



A little later (she had fed well meantime) she refused a F. lymus and a grass- 

 hopper 1061, then i^efused, tasted slightly and rejected first a Pitthea continua, then 

 a Papilio echerioides S , and thereafter refused to touch them again, refusing with 

 equal persistence to taste an Antanai'tia schceiteia, an E. hiarhas, and a Gharaxes 

 nalalensis. All were offered with their upper surface fully displayed. On my 

 offering them with the under surface up, the moth was still refused but the 

 Antanartia readily accepted, though thrown away after thorough tasting. The 

 P. echerioides S and the E. hiarhas were persistently refused, but the G. brutus 

 accepted, eagerly crushed, and swallowed. 



[Summary: — A. johnstoni was preferred to A. igola cj" and to A. caldarena, and 

 the latter at any rate not liked appreciably better than A. igola. At this point of 

 considerable hunger very little feeding produced a refusal of A. esebria $ , 

 N. leUjGonoe, A. lohengida, and A. albimacidata, all of which might, therefore, be 

 presumed to be low-grade. G. brutus natalensis was preferred to A. schoeneia, 

 E. hiarhas, P. echerioides d , P- lyceus, Pitthea continua, and grasshopper 1061. 

 A good mimicry experiment, the bird distinguishing by their under surface butter- 

 flies resembling each other on the upper surface.] 



Exp. 191. — March 2. I fed the roller on meat (the lights of a freshly killed 

 sheep) till he would eat no more; he persistently refused the last piece with shakes 

 of the head ; then offei'ed a Terias senegalensis and a M. yulei, both of which were 

 accepted and eaten, though an A. johnstoni was refused. She then refused to touch 

 an A. dominicanus, or, after it, a black and white 5 A. esebria, cautiously tasted 

 an A., neobide and rejected it, thereafter refusing persistently to touch either it, a 

 bright (S M. igola, or a 5 ^- doubledayi with a slightly clear- wing appearance, 

 refused to taste either a Nychitona medusa or a liedoa vielanocras2ns , both, as also 

 the preceding offerings, offered with wings spread and upper surface shown. Ate 

 two grasshoppers, then persistently refused to touch a M. rueppelli or a Mylothris- 

 mimic, but accepted hesitatingly, then readily ate, a Phrissura isokani S . 



IT. senegalensis and M. yulei were preferred to the meat, and, at any rate, 

 probably not liked less than A. johnstoni, A. dominicanus, A. esebria $ ,-4. neobide, 

 A. igola J , A. doubledayi J , L. medusa, Ouud liedoa melanocraspis. c? Phrissura isokani 

 was preferred to M. ruejjpelU, and was tried, though hesitatingly, where a more 

 definite mimic was refused. It was perhaps of interest that A. neobule, the first of 

 its colour to be offered, was tried, while the second, A. doitbledayi Si with a clear- 

 wing appearance, was refused.]
