Dr. G. D. H. Carpenter’s Experiments on 
each side of the thorax. A pair, in copula, found 
sitting conspicuously exposed, on a leaf of a bush. 
One was offered to M., who took and ate it without 
hesitation. 
Obs. 466. Sp. 186.—Catantops decoratus : three 
staple grasshoppers eaten readily. 
Obs. 467. Sp. 225.—Tenebrionid, Rhylinota acuti- 
collis Fairm.: like 69 (Obs. 133), a smooth, black, 
polished beetle. Found under a stone, but others 
often seen running conspicuously in the sun. M. paid 
no attention to it crawling in front of him till I 
pushed it towards him, when he bit it in half, and 
hurriedly spat out the piece in his mouth. 
Obs. 468. Sp. 226.—Lamiid beetle, of fair size, dull 
blue-black, spotted with buff, procryptic. Offered to 
M. on my fingers; he seemed to know the beetle 
from some distance away, ran up and seized it at 
once. He bit off its head, and ate it, then looked 
attentively at the body before eating it all. 
Obs. 469. Sp. 186.—Catantops decoratus: three 
grasshoppers eaten, but not very hungrily. 
Obs. 470. Sp. 227.—Blattid: a male cockroach of 
the usual light brown colour, was given M. in the 
afternoon. After a little hesitation he bit off its head, 
but did not seem to like it much, he merely pulled 
the body about and played with it. 
Series Bc. Obs. 471-484. Jan. 27.—At10a.m. M. had had 
as much vegetable food as he wanted, but squealed 
with excitement when he saw me bring the insect 
boxes. So I gave distasteful species first— 
Obs. 471. Sp. 215.—Tenebrionid, Catamerus revoili : 
M. looked long at it, turned away, looked again, picked 
it up and bit it. A droplet of yellow oily fluid came 
out from between thorax and abdomen, and M. at 
once dropped the beetle. 
Obs. 472. Sp. 13.—Tenebrionid, Macropoda trans- 
versalis: when I put this beetle down, M. looked 
disappointedly at it for some time, then took it and 
ran about with it in play, put it in his mouth, crunched 
it a little, then took it out and put it down. 
Obs. 473. Sp. 228.—Coreid, Cletus ochraceus H. 8. : 
a small, brown, plant-feeding bug, procryptic. Put in 
mouth and rapidly eaten with face rather doubtful 
and expressive of dislike.
