EXl^LANATION OF FOEM AND COLOURING. 369 



Exp. 216. — March 8. After a few grasshoppers, would have nothing to do with 

 an A. caldarena or a Terms brigitta, and on my persisting in offering them snatched 

 each from the forceps and Avithout attempting to taste or crush it dashed it on the 

 ground. But he at once accepted and ate a Sph. clilorea. Tlie next four ofierings 

 were four days old and dry, but Avere offered to test his previous knowledge of 

 insects of tlaeir respective colour-patterns. He refused to touch a Redoa melano- 

 craspis, at once accepted a Neptis goochi, but after crushing it threw it away, 

 presumably because dry, persistently refused without tasting a " Terias Teracolus" 

 but readily enough accepted a Myc. campina, and treated it as he had done the 

 Neptis. He then refused to touch an Atdacopliora vinula, tasted and dropped a 

 grasshopper No. 47, then picked it up again, crushed it and threw it away, ate a 

 grasshopper 1051, at once accepted but, on crushing it, threw away a Mylahris 

 ocidata, readily accepted and ate a P. demodocus, an L. thalassina S and a C. 

 brutus, refused persistently to touch a Lye. lemnos, but readily accepted and ate a 

 $ Gre7iis hoisduvcdi oftered underside uppermost. He now refused to accept 

 grasshopper 47, readily ate grasshopper 1061, refused 47, tried and rejected 1051, 

 readily ate the common grasshopper with red wings and block and white mai'ks 

 under thorax, ' readily ate No. 86, refused 1051, readily accepted and ate 

 1061 and 19, then barely tasted and emphatically refused 19, 1061, and the 

 white-chequered one, refused emphatically and persistently without trial 

 A. cdbimacidata (outspread upper surface) and D. chrysippus (underside), but 

 greedily accepted and swallowed the Yery large moth, Nyctipao macrops, and showed 

 the greatest eagerness for a Ch. briitus, which, however, I required for another 

 experiment and withdrew. But I shortly afterwards offered him a Ch. candiope^ 

 which he at once swallowed, as usual, wings and all. 



It surprised me in the above experiment that the roller was apparently less sure 

 of his beetles and grasshoppers than of his butterflies. 



One-and-a-half hours later, no food meantime, tried and rejected a house-fly 

 {M. domestica) aiid a hive-bee, tried and lejected a S grasshopper 1051, dropped, 

 then ate a 5 and readily accepted and ate a smallish Acriditwi lineatum. No 

 hesitation had been shown in tasting the house-fly and very little, if any, over the 

 hive-bee. It had now clouded over heavily, and it is possible that if he knew the 

 insects' placings well already it was too dai-k in the verandah to allow of certain 

 recognition.
