Fifteen minutes later she tasted and rejected Eurytela dryope^ but crushed and 

 readily ate Papilio lyceus and Papilio demodocus, then obstinately refused Eurytela 

 dryope without tasting, then ate four smallish grasshoppers and refused the next, 

 also refusing Papilio lycei(,s, then three more grasshoppers and refused the next, 

 also Antanartia schceneia. After a short interval A. schceneia and P. cehrene were 

 once more offered, as well as a number of grasshoppers, but all were refused without 

 tasting. 



[Summary: — (1) "There could be no doubt of the roller's enjoyment of the 

 Encosternum, which was eaten in preference to the usually highly-placed Precis 

 cehrene."

(a) 1. N. saclava. 



Cryptacrihs r2, Terias senegalensis and Phymateus (latter if not result of 



comes. < stimulation).

(b) 1. Encosternitm delegorguei (small grey sp., at any rate, not 



liked better).

Exp. 68. — August 6. Tasted and rejected Myloihris agathina $ and Terias 

 brigitta, afterwards refusing to touch the latter most obstinately. I then offered 

 it a dull green Phymateus (a large specimen). The bird, though hungry, refused 

 to have anything to do with it, retreating away along the perch whenever I brought 

 it near. I then substituted for it Phymateus viridipes. The I'oller, which had 

 retired to an inaccessible corner, at once on seeing it flew up, seized it, and after 

 crushino- it well, swallowed it with no indication of dislike. She then tasted and 

 reiected once more the Terias, but crushed and very readily ate an Ypthima, of 

 which there are still a good ma,ny about. 



rSuMMARY : — (1) Note: " The dark green Phymateus was remembered with such 

 evident dislike that though there was still nothing to indicate that it should be 

 placed below Terias it would, I believe, have been placed well below it had the bird 

 been hungry enough to eat that butterfly. The red- winged Phymateus viridipes 

 was liked very much better, though not necessarily more than Ypthimar 



(2) Grades: — 



1. Red-winged Phymateus and Ypthima. 



2. Dark green Phymateus, T. hrigitta, and M. agathina $ .] 



Exp. 69. — Augiost 7. Refused without tasting, then simply took from the forceps 

 and threw away Mylothris agathina, refused also but then tasted slightly and 

 threw away a Terias, but crushed and readily ate a Mycalesis camjAna, tried to 

 crush biit finally rejected in annoyance or despair a very hard Acridium lineatum, 

 ate three smallish grasshoppers, refused persistently without tasting Neptis saclava, 

 crushed and at once rejected Eurytela dryope, crushed well and rejected, though 

 less promptly than the Eurytela^ a Leuceronia argia $ , and crushed and ate (it
