Alcena 

 nyassa. 



ex:planation of form and colouring. 357 



'2. Moth, the three Lycsenids, Terias regularis (and probably 

 T. sengcdeihsis, Myc. cainpina)^ grasshoppers. 



3. Hcematopota nr. brunnescens, housefly, Peltacanthina, Mylabris 

 oculata. 



Phrissura isokani Avas eaten in preference to grasshoppers, but not tested against 

 the rest, though it is probably not lower than the Alcena, refused just after its 

 acceptance.] 



Exp. 182. — December 27. Readily ate Belenois mesentina and three grasshoppers, 

 then tried and rejected scented Longicorn {Closteroynerus viridis), ate readily 

 B. mesentina, twice failed with a Buprestid, Psiloptera cognata, it glancing out of 

 her bill each time. 



\_Closterovie7'us and the Psilopte7^a (in virtue of hardness and gloss) below B. me- 

 sentina.] 



Exp. 183. — January 8, 1911. Fairly hungry, crushed without any great difficulty 

 and ate a dung beetle, Gatharsius rhinoceros 2 . The thorax with elytra attached 

 fell away during crushing. 



Crushed and ate a round forest " woodlouse " isopod. 



Exp. 184. — January 10. Fairly hungry. Refused decidedly without tasting 

 a blister beetle, Lytta tlioracica, then took a Locustid, Enyaliopsis petersi, by the 

 thorny thorax exuding juice, pressed it, and threw it away, refusing to have any 

 more to do with it. 



Exp. 185. — January 12. Fear of owl. A barn-owl {S.flammea), dead, but with 

 eyes open and held in a life-like position, was shown to the birds to-day. Roller 

 indifferent. 



Exp. 186. — January 13. Fairly hungry. Pressed a dung beetle, Gymnopleurus 

 fastiditus, and as it did not yield threw it awa}^ The same with a second. But a 

 Micrantereus vicarius crushed more easily and was swallowed. She then tried and 

 rejected, failing to crush it, a large weevil (Brachycerus), but accepted an Enya- 

 liopsis j^etersi, which she battered into a pulp and swallowed. She kept closing 

 her eyes or drawing the nictitating membiune across as she did so, but I think 

 that it was only when one of the locust's tarsi approached an eye, and not in con- 

 sequence of the latter's unpleasant qualities. 



\_Enyaliopsis petersi and Micrantereus vicarius less well protected relatively to the 

 roller than Gymnopleurus fastiditus and the Brachycerus^ 



Exp. 187. — January 14. Alarmed at a large live Amphisbsenid, but only very 

 moderately so. [To test knowledge of harmlessness.] 



Exp. 188. — February 1. Tried and rejected an Amauris alhimaculata. Refused 

 without tasting Acrma joJinstoni. 

 [A mimicry experiment.]
