342 Mr. G. A. K. Marshall on 



evident appreciation. C. o-upkoloides 

 appeared to have become tired of butter- 

 flies, refusing all, even those it ate before. 

 Swynnerton found that it continually 

 refused the brightly-coloured grasshopper 

 mentioned above, but always ate it with 

 relish when it had been dipped in meal 

 to obscure its colours. C, naumanni on 

 the other hand never refused the insect. 

 January 22. G. naumanni accepted a Papilio corinncus, 

 but seemed in some doubt as to its 

 edibility; he finally ate the thorax and 

 threw away the abdomen. Acr^ea halali 

 was then offered, tasted, and rejected. 

 AeriBa anemosa and Liinnas chrysipiyus 

 were likewise refused, and shortly after- 

 wards one Byblia ilithyia and one Terias 

 hrigitta were eaten. 



„ 23. C. ru2ncoloid€S escaped, and all the follow- 

 ing notes refer only to G. naumanni. 

 Kestrel ate one DicMha injiata and one 

 AmUy sterna vitti2')cnnis. A Lagria, sp., 

 was tasted and rejected. 



„ 25. When very hungry the bird ate part of an 

 AcVcVa caldarena, throwing away the rest. 

 Subsequently he ate iouv Belcnois sevcrina, 

 one Junonia cchrene, and one Precis sesamus 

 {natalciisis form). 



„ 28. Two Bi/hlia ilithyia eaten by kestrel. A 

 Clythrct wahlbergi, with strong Coccinellid 

 odour, was eaten by the kestrel after 

 some hesitation. Kestrel refused the 

 Coccinellid JE^^ilachna, drcgei. 



„ 29. A Longicorn (Geroptesis fcdlax, Per.) offered 

 to kestrel, which had been kept without 

 food for some time. He was evidently 

 nervous and much impressed by the 

 stridulation of the insect. I therefore 

 pulled the head off the beetle, and the 

 hawk then ate it, but very slowly and in 

 such a way as to lead me to suppose that 

 it was not altogether palatable. Gave 

 aPiezia scloHsi,he&d first, to kestrel, wliich 

 ate it readily though evidently noticing
