EXPLANATION OF FORM AND COLOURING. 269 



ate a large Mycalesis, refused for some time but finally tasted and swallowed 

 a Henotesia perspicua, again refused but eventually tasted and ate an Ypthima. 

 But she refused persistently to have anything to do with the next, tasted and 

 rejected Neptis saclava, refused without tasting but finally tasted and pitched 

 away an Ypthima, and obstinately refused the next without tasting. She now 

 refused without tasting two small Pinacopteryx (one white, the other orange- 

 based). 



Ten minutes later she accepted the white Pinacopteryx (small), crushed it very 

 thoroughly and rejected it, but readily ate Neptis saclava, then refused persistently 

 and emphatically with shakes of the head a Terias. Phrissura isokani S , wingles?, 

 was now tasted and rejected. 



[Summary, etc. : — (1) Note at the time : " The bird was distinctly suspicious of the 

 small dark brown Henotesia perspicua, no doubt confusing it with Mycalesis campina 

 and Ypthima. Immediately afterwards she was reassured (or so it appeared) by the 

 comparative palatability of the Henotesia (or else appetized by it) into eating what 

 she had probably wished to avoid — Ypthima itself."

Exp. 51. — Ju7ie 26. To place Pseudacrcea trimeni. I found the roller hungry 

 and gave her a full feed of meat, variovis grasshoppers, and a large beetle-grub, 

 followed by more grasshoppers. She finally refused to touch anything more. 

 Five minutes later she consented to eat two more small grasshoppers but with 

 complete disinclination, and refused to touch another, though various species were 

 ofiered. She now refused without tasting a Precis cebrene, tasted very slightly 

 and dropped Tagiades Jlesus, crushed well and, after a little delay, the result of 

 repletion, ate a Pyrameis, crushed and readily ate a Macroglossa trochilus, evidently 

 liking it. She now ate, though again with disinclination, two grasshoppers of a 

 very favourite species (previously refused) and after them readily enough another 

 Pyrameis. She now refused without tasting a Pseudacrcea trimeni with, as usual, 

 one wing attached, but, tempted by its violent movements, accepted it, crushed its 

 thorax thrice, and then dropped it. She then refused without tasting Papilio 

 lyceus § , Neptis saclava, and Precis cehrene, and crushed very slightly and dropped 

 Pyrameis cardioi. 



The Pseudacrcea was still alive, but unlikely to survive its injuries for long. 



Ten minutes later the bird crushed and dropped a Pyrameis, and refused without 

 tasting a Gegenee. 



Ten minutes later she again crushed and dropped a Pyrameis, but on my reoffering 

 it ate it readily enough, refusing, however, without tasting a Precis cebrene and a 

 Pseudacrcea trimeni.
