Exp. 116. — December 6. Fed on grasshoppers till she would eat no more ; readily 

 ate two winged termites, a Oatocaline moth {Ojyhiusa lienardi) and a Rutelid 

 beetle {Adoretus sp.), as also another termite ; crushed and rejected an orange- 

 banded Longicorn, Cymatura bifasciata, but readily ate yet another termite. 



[Probable order : — 



1. Termite, Ophiusa lienardi, Adoretus sp. 



2. Grasshoppers, Cymatura bifasciata. The latter, however, was 



definitely tested only against the termite.] 



Exp. 117. — December 7. Distinctly hungry. Crushed and at once rejected the 

 Arctiid moth, Diacrisia maculosa, exuding juice from before thorax, as also 

 an unidentified Coccinellid, refused persistently to taste Upilachna hirta, but 

 eagerly accepted and ate a Mycalesis campina and a Terias, refused, then 

 hesitatingly tasted, and withdrew without accepting an Acrcea caldarena, and once 

 more, this time after a more thorough tasting, rejected the Diacrisia. 



I then fed her on various Orthoptera till she would absolutely eat no more. 

 After this she refused for a time to accept Papilio angolanus, but finally just tasted 

 a len- and withdrew with a shake of the head, then accepted with a certain amount 

 of hesitation, due perhaps to its brilliant coloration, the front half of a full-grown 

 larva of Acherontla atropos wliich I had that moment cut in two, but dropped it. 

 This was probably, however, either the result of accident or of the surprise due to 

 the sudden rush of its copious internal juices into the bird's bill, for on my 

 reoifering it, it was readily accepted, crushed and battered against the perch and 

 swallowed. The bird now refused without tasting an An-ugia basuta $ , a 

 C'atacroptera cloantha, a Gatopsilia florella, and a Precis cebrene, being to all 

 appearance replete. She kept wiping her bill, however, at intervals and shaking 

 her head, which I took to be possibly a sign that she regretted having eaten the 

 larva (though it may have been simply a matter of its juices), so fifteen minutes 

 later I offered the other half. The bird looked at it and sidled up towards it from 

 the other end of the perch, but did not at once accept it, leaning forward on arrival 

 but then drawing back once more with a shake of the head. A few seconds later 

 she tasted it half-heartedly and again drew back without having accepted it. She 

 then refused, but changing her mind accepted, crushed and ate a Catacroptera 

 cloantha, but refused persistently to taste a Precis cebrene or a Gatopsilia florella, being 

 evidently too replete for them. 



The " death's-head" larva evidently continued to tempt her nevertheless, for on 

 my now at once reofiering it she once more leant forward and closed her bill on it,
