EXPLANATION OF FORM AND COLOURING. 367 



A little later again she crushed very thoroughly indeed and ended by swallowing 

 a Xylocopa africana, refused a second, also S Xylocoya senior and the third species, a 

 Mylothris yulei, and a piece of meat, accepted a Terias hrigitta, but, after a great deal 

 of crushing and an evident inclination to eat it, rejected it and very readily 

 accepted, crushed slightly, and swallowed a Belenois mesentina, afterwards once 

 more refusing the bees. 



[Oi^dei' : — ■ • 



1. B. mesentina. 



2. Perhaps, on manner, .Terias hrigitta and senegalensis and 



Xylocopa africana. 



3. The other Xylocopas, M. yulei, and lamb.] 



Exp. 212. — June 5. Hungry, just before morning meal, readily ate a (5 AcroeM 

 Serena, crushed and rejected in tiu-n an A. asema and an A. caldarena, readily ate a 

 5 A. sereua and two pieces of meat, crushed slightly and rejected Xylocopa africana, 

 refused to touch either it or Xylocopa sp. and X. senior c? , crushed and rejected 

 ei (S A, serena, and readily ate a Mylothris yulei. 



I kept reofFering the three bees at intervals, S X. senior usually first. Some- 

 times they were refused without tasting, sometimes merely taken in the point of 

 the bill, crushed slightly, and dropped ; none eaten or even accorded anything like 

 a serious crushing. 



On the last occasion the roller crushed slightly and rejected an A. serena and, in 

 turn, the three bees, refused these, again crushed slightly and rejected the A. serena, 

 but accepted, crushed, and readily ate a (S ^i- agathina and a piece of meat. 



[Order : — 



1. S ^J' agathina and, perhaps, lamb. 

 Xylocopa \ 2. A. terpsichore. 

 spp. 3. [ 3. A. caldarena and A. asema.'] 



Exp. 213. — Jime 6.— Refused to touch A. caldarena, crushed slightly and dropped 

 A. serena, refused, then accepted, crushed slightly, and rejected two moth-larvse 

 eaten by the natives, refused to accept an A. esehi'ia, an A. serena, or a Mylothris 

 yulei, but very eagerly seized on, crushed, and swallowed a Belenois 7nesentina, 

 evidently much preferred to any of the others. 



Exp. 214. — J'mie 7. Probably quite hungry; before early morning feed. Readily 

 accepted, crushed, and swallowed four Termites (two small soldiers and two small 

 workers) . 



[Returning in the evening, after an absence, I found that the hornbills had 

 pulled out several trays and that the roller and P.layardi B had in consequence 

 escaped, while the kingfisher had found his way into the roller's cage. A careful 

 search, continued throughout the next morning, failed to discover the roller ; her 

 wirigs were in excellent condition and she had possibly flown away. But the bulbul 

 returned on the 8th with a request for re-admission.]
