8 Dr. G. D.H. Carpenter’s Experiments on 
Observation 1. Species 1.—A Cassidid beetle, Cassida 
sp.: typically aposematic, found freely exposed on 
low herbage, bright orange with bold black spots. 
M. made eager preparations for taking it from off my 
finger, but as it got nearer it could be more clearly 
seen, and M. did not snatch at it, but took it care- 
fully, examined it, put it into his mouth without 
any appearance of eagerness, crunched it slowly and 
rather doubtfully, eventually either swallowing it or 
putting it in his cheek-pouch. I gave him another 
and he examined it and pulled it to pieces, smelt it, 
and slowly ate it without enthusiasm. 
Obs. 2. Sp. 2.—Clytrid beetle, Clytra wahlbergi Lac. : 
fairly large, black and scarlet, sits freely exposed on 
low herbage, typically aposematic, offered to M. on 
a finger; he examined it and crunched it up without 
any enthusiasm, and brought it up again into his 
mouth to be again masticated as if very doubtfully 
worth eating. 
Obs. 3. Sp. 3.—Phytophagous beetle, Physodactyla 
gerstaeckert Jac.: a jumping species, bright orange, 
very conspicuous and typically aposematic, found on 
same plant as No. 1, and with it. This was pulled 
to pieces, smelt, rubbed with the hands, and finally 
dropped. I picked it up and gave it to M. again; 
he pulled it about, but finally ate a little. 
Obs. 4. Sp. 2.—Beetle, Clytra wahlbergi. Looked 
well at, smelt, pulled to pieces, eaten without 
enthusiasm. 
Obs. 5. Sp.—.—Acridiid: a small procryptic 
brown grasshopper was brought to M., who was 
wildly excited as he saw it coming, seized it with the 
utmost eagerness and crunched it up with every 
indication of relish. 
Obs. 6. Sp. 4.—Hesperid butterfly: a black and 
white ‘chequered skipper,’ was also taken and 
eaten with gusto. 
Series B. Dec. 29.—The monkey was now in my hands, 
and I was able to control its feeding. About 10.30 
a.m., M. being very hungry, I gave him a banana, and 
when about half eaten took it away and offered— 
Obs. 7. Sp. 5,.—Acridian, Zonocerus elegans Thunb.: 
a “ poisonous-looking,” large, freely exposed, clumsy 
grasshopper, bright yellow green with undeveloped
