and a Mycalesis campina, refused the Discolia persistently without tasting, readily 

 ate an ant-heap larva, and crushed and rejected a Dielis ^-fasciata var. viansueta. 

 No fear had been shown of the wasp. 



Five minutes later she again crushed thoroughly and threw away both wasps, 

 refused persistently without tasting a very hairy Arctiid larva, ate four grass- 

 hoppers and refused the next three, but i-eadily ate a P. angolamis, ate four more 

 grasshoppers including those previously refused, crushed well and threw away 

 P. angolamis, approached with suspicion the Psychid larva with "house" removed, 

 tasted it slightly and rejected it, I'efused persistently to take the Arctiid larva or 

 the Psychid larva reoffered. By no means yet replete. 



[Probable order : — 



1. Grasshoppers, P. angolamis, M. campina. 



2. Discolia alaris, Dielis 5-fasciata var. mansueia, Arctiid larva. 



The Psychid larva deprived of its covering was offered and rejected when 

 P. angolanus was being refused, but the bird was still by no means replete.] 



Exp. 135. — Jamiary 11. Readily ate one Mycalesis campina find three Fo7'micaleo 

 leuGospilus, first crushing each slightly, pressed two or three times in her bill and 

 flung right away a brilliant red millipede (Spirolobus sp.), crushed and rejected 

 a small bine-black Phytophagous beetle, very readily ate another adult a,nt-lion, 

 crushed and at once rejected a large green and yellow Phytophagous beetle, 

 Diacantha petersi, readily ate a Mycalesis campina, crushed very thoroughly 

 and finally rejected the dull bronze-green beetle, Lagria villosa, and readily ate 

 another ant-lion. I then gave her a number of grasshoppers, after which she 

 crushed well and rejected the ant-lion, accepted and ate a Mycalesis campina, took 

 in the point of her bill, crushed slightly, and rejected an ordinary unswollen tick of 

 our commonest species (Ehipicephahis sp.), ate five more grasshoppers large and 

 small, the last three with disinclination and refused obstinately to touch any more, 

 refused with equal obstinacy Mycalesis campina and P. angolamis, crushed 

 thoroughly and threw away an Asilid fly, Alcimus rubiginosus, and crushed and 

 flung away a Muscid fly that, sombre enough in colouring, is conspicuous through 

 its habit of settling on the upper surface of large leaves in the forest ; it seemed to 

 me that she liked it less than the Asilid. She then refused even to taste an ant- 

 lion, crushed well and rejected P. lyoeus, first with wings, then without, readily 

 accepted and ate P. cebrene, crushed well and rejected E. hiarbas, accepted a large 

 E. neophron 5 with all its wings attached, held it for a minute or two in her bill, 

 crushing it at intervals, then tossed it away. As the action was indicative of 

 disinclination rather than of dislike, I at once removed three of the wings and 

 reoffered it, when it was at once readily crushed and eaten. The bird then 

 accepted a C.florella with disinclination, crushed it, and dropped it. 



Five minutes later she refused Pap. lyo'Ms without tasting, readily ate two 

 Precis artaxia f. and a C. cloanthe (this was held for a minute or two, the bird 

 being replete), and then refused without tasting G. cloanthe, P. artaccia, G.florella^ 

 and P. cebrene.
