Exp. 136. — January 12. Crushed and ate a small green Phytophagous beetle 

 (no smell and no exudation), refused, then tasted very slightly, and again refused 

 a Mylahris ocidata, definitely crushed and rejected another Myki.bris, retreated 

 from a 5 Zonocerus elegans with very evident annoyance at its smell (sharp head- 

 shakings, etc., which she at once indulged in whenever I brought it within two or 

 three inches), refused pei'sistently without tasting un undetermined beetle, 

 crushed and threw away a bug, Lygceus swynnertoni, reached hesitatingly toward 

 a large black millipede {Spirostreptus sp.), but retired with some slight display of 

 hoi-ror on its commencing to squirm in the usual semi-spiral fashion, refused for a 

 second, then tasted and rejected Epilachna hirta, refused persistently without 

 tasting an Aulacophora sp., which doubtless reminded her of it, crushed thoroughly 

 and ate a huge black Locustid of sluggish and conspicuous h&hitsi {.Mirtinermus sp.), 

 and persistently refused without tasting a larval Zonocerus elegans. 



Perhaps twenty minutes later she refused for a time, then, on my continuing to 

 present it, definitely tasted and rejected the Aulacophora, which smells as strongly 

 as any other of our Phytophaga, and accepted a small portion of the above- 

 mentioned black millipede ; but on her exerting pressure it slipped from her bill, 

 being very hard and glossy. I therefore crushed it and reoflered it, when it was 

 subjected to somewhat prolonged crushing and thrown away. 



[The Mimnermus was preferred to the other insects used before the interval, 

 and the millipede, after it, was shown more consideration than the Axdacophora. 

 Its main defence, consisting in the emission of a pungently-smelling secretion, was 

 doubtless lacking in the mere fragment ofifered.] 



Exp. 137.— At noon, distinctly hungry once more, she did her best to crush 

 a weevil (JSTo. 128), even battering it well against the perch, but failed to make 

 the least impression on it, and finally threw it away. She re-accepted it, but 

 again failed to crush it though pressing with all her force, and threw it away, 

 refusing to touch it again. However, she readily accepted, crushed, and swallowed 

 another weevil {Ipliisomus sp.), tasted and rejected a Chrysomelid, Gladocera 

 femoralis, and crushed and swallowed Horatopyga sp. (similar but duller), readily 

 ate after crushing it thoroughly a mantis egg-case and a Mycalesis campina, per- 

 sistently refused to taste a Mylahris ocidata or a 5 Zonocerus elegans, and accepted 

 doubtfully but then readily ate two fully gorged ticks of our commonest species. 



[The /pA^som?^s was eaten readily and easily when 128 had proved impossible; 

 the mantis egg-case, M. campina., and full-fed ticks were placed above Gladocera
