and rejected it with disgust, refused an Epilachna hirta, refused, then in turn 

 tried and threw away, an Amauris alhiinacidata, an Acrcea ccddarena, and an 

 A. igola S, but readily accepted, crushed, and ate an Mylothris rioeppelli. 

 \_M. ruepjyelli preferred to each of tlie other insects.] 



Exp. 201. — April 18. Very hungry. Tried and rejected a larva of A. albimacit- 

 lata, refused, then tried and rejected A. ccddarena and A. esehria 2, accepted, 

 crushed, and ate a B/iodogastria bubo (foam exhausted) and an M. yidei, tried with 

 her bill and refused to take a large weevil {Brachycerus apterus) and a Psammodes 

 mashunus^ and i-efused to even taste a Psammodes sp. or a Psammodes perjidus, 

 again refused A. caldarena, but took another Rhodogastria, and crushed it well 

 before throwing it away. 



I then gave her a feed of grasshoppers, after which she refused, then tried and 

 rejected, a hive-bee, and refused to taste again either it, a Podalirms vestitus, 

 or two flies mimicking Hymenoptera, ate a few more grasshoppers, tried and 

 rejected a bee (Xylocopa), and refused to touch again either it or large flies with the 

 same colouring, refused persistently with shakes of the head to taste a Lycoid Lygteid 

 bug, accepted a Lycoid JVupserha, and crushed it very thoroughly before throwing 

 it away — evidently it was not very highly disliked, — then refused to touch a 

 Myc. campina or a Papilio angolamcs, but readily ate a Charaxes hrutus nataleiisis, 

 wings and all.

Also a mimicry experiment, Dipteron mimics of Hymenoptera being tested and 

 two members of the Lycoid group. The Lycoid Lygseid, though not actually 

 tasted in this experiment, is actually very low grade indeed, and the Nupserha, 

 whose Lycoid coloration failed to save it from tasting, was shown to be, if any- 

 thing, probably more acceptable than M. campina and P. angolanus.'] 



Exp. 202. — April 18 (continued). Later in the day (had had a feed meantime) 

 refused, then barely crushed and dropped, a Belenois mesentina, readily ate a Myc. 

 campina and a small piece of meat, refused to touch a second small piece of meat or a 

 second M. campina, but readily ate after crushing each a Glutophrissa saba {ochlea- 

 like), a P. isokani d , and a Teracolus achine 5 , refused to touch M. campina, but 

 readily accepted and ate Neptis agatha and Byblia goetzius.
