EXPLANATION OF FORM AND COLOURING, 365 



Later. I had just placed in her cage a feed after a hungry spell, when it struck 

 me to offer the pupa of A. alhimactdata. She had already eaten the first grass- 

 hoppers, and she attacked and crushed well, then threw away, the pupa. As she 

 at once continued her feed, it was useless to offer anything for comparison with the 

 pvxpa, but it was evidently fairly strongly disliked.

Exp. 205. — April 30. Refused to touch or taste a driver-ant, Borylus sp., with 

 shakes of the head, but accepted, crushed, and ate an A. ierpsichore. 



Exp. 206. — May 2. Should have been very hungry before morning meal, which 

 was in any case late, Refused, then barely tasted and threw away, an Epilachna 

 hirta, refused, but quickly tasted slightly and rejected, a turnip sawfly larva 

 {Athalia sp.), ate fairly readily five coffee-bugs {Antestia lineaticollis), refused, and 

 on my continuing to hold it to her tried and rejected, A. albimactdata, refused 

 A. neohide and A. serena, refused, then barely tasted and rejected, A. serena, tried 

 and rejected A. cabira, but ate with hesitation another coffee-bug. 



Considerably later, no food meantime, she I'efused another coffee-bug, and after 

 it once more refused to touch a Mylabris, Epilachna hirta, the sawfly larva, 

 Amait7'is albimaciolata, Acrcea neobule, A. natalica, A. bitxtoni, A. cabira, again the 

 coffee-bug, and a M. rueppelli, bixt very readily accepted and ate &Belenois mesentina.

Exp. 207. — May 3. Crushed well and swallowed a swollen cattle-tick (Rhipi- 

 cephalus sp.), tasted and rejected a black recui"ved ant [Polyrhachis gagates), a 

 grey ant, an unswollen tick, a driver-ant [Dorylus), several fruit-flies ( Ceratitis) 

 held together in the points of the forceps, but evidently regarded two or three 

 black aphides (of orange) as too insignificant to deserve attention, most per- 

 sistently refused without tasting Amauris albimacidata, crushed slightly and 

 rejected in turn Acrcea serena, M. agathina $ , and a T. senegalevsis, but 

 readily accepted and ate B. mesentina, again tried and rejected fruit-flies {Ceratitis)^ 

 ate a fly of the species used for the "drivers" the other day, but looked 

 exceedingly doubtful after it and shook her head. She refused to accept a second, 

 but after some persuasion on my part tried it and threw it away, then readily ate 

 a full-fed cattle-tick, and after a great deal of battering an Enyaliopsis petersi. 



[B. mesentina, a full-fed cattle-tick, and probably Enyaliopsis petersi preferred to 

 any of the others, including T. senegalensis and unfed cattle-tick of same species. 

 The eating of fly was probably a mistake.]
