818 MR. R. t. POCOCK ON THE 



bird, aftei" waiting a short while, tried it again, but finally left it 

 alone. 



It was then taken by a Dial Bird, which, after pecking it about 

 for a short time, was robbed by the Sulphury Tyrant. The latter, 

 after tasting it, left it alone. I then gave the remainder of the 

 insect, consisting only of the thorax and wings, to a Yellow- 

 crowned Hangnest, which took it to a pei'ch, and holding it in one 

 foot gradually pecked away the wings and dropped theiri, and 

 then pecked the thorax to pieces, eating little bits of it and 

 dropping others. 



Pupa of the Large White (Pieris brassicce). 



Oct. 26, 1909. One offered to the Dial Bird which had fifteen 

 minutes previously eaten the larva, but he would not touch it. 



Offered to Yellow-crowned Hangnest which had tasted and 

 dropped the larva. He looked at it but would not touch it. 



Given to Harmonious Shrike-Thrush, which behaved just as 

 the Dial Bii'd had behaved with the larva,, pecking it and dropping 

 it repeatedly to shake his head. He was then robbed of it by a 

 Common Mocking Bird, which, however, dropped it in the grass 

 from the perch, and made no attempt to recovei' it. 



One oftered to a Black- winged Grackle, a Javan Pied Mynah, a 

 Fantailed Flycatcher, and a Sulphury Tyrant, all of which tasted it 

 once, but not a second time. A Common Mocking Bird persevered 

 a little longer, but finally dropped it and made no effort to pick 

 it up again. Given to Harmonious Shrike-Thrush, was eaten 

 without much hesitation. 



Larva of the Large White (Pieris brassicce). 

 Food not recorded. 



Oct. 26, 1909. One taken by Yellow-crowned Hangnest, but 

 soon dropped. Pounced upon by Dial Bird, which after many 

 trials, pecking it and shaking his head after every taste, at last 

 swallowed it ; but he was evidently veiy uneasy for some twenty 

 minutes afterwards, pei'iodically shaking his head and opening his 

 mouth and straining as if tx-ying to vomit something nauseous. 



Larvae of the same fed on Tro2xeolum (so-called Nasturtium). 



Sept. 13, 1910. Three eaten readily by Silver Pheasant and 

 Reeves's Pheasant. 



A small one given to Pekin Robin, which obviously did not 

 like the flavour. He pecked it abovit in the sand for a long time, 

 vigorously shaking his head after each taste. Ultimately, how- 

 ever, he ate it. I then gave him as a test the larva of a Noctua 

 (see p. 835), which he also took and very soon swallowed entire 

 without once shaking his head or evincing any sign of dislike. 

 He then took a second and lai-ger hrassicce-larwa., treating it just 

 as he did the first, but tackled it with still greater reluctance,
