28 Dr. G. D. H. Carpenter’s Experiments on 
Obs. 168. Sp. 81.—Phasmid: I saw M. looking 
very carefully at the top twig of a low bush, round the 
foot of which he walked, and then suddenly took 
from it a brown stick-insect about two inches long, a 
species commonly found among grass. Presumably 
at first M. was not sure of it and it then gave itself 
away by moving. 
Series Y. Obs. 176. Jan. 5. 
Series Z. Jan. 12.—Since last observation I had been away. 
The monkey had had very little insect food during 
that period. In afternoon, M. having had some 
banana, I offered him— 
Obs. 177. Sp. 86.—Lycid, Chlamydolycus trabeatus 
Guér.: a 3, with elytra enormously developed, pro- 
jecting far beyond the small body—a very conspicuous 
beetle. M. looked well at it, at last taking it in his 
hand and dropping it again. I could not induce him 
to do more than smell it once, when he instantly 
dropped it. 
Obs. 178. Sp. 87.—Lygaeid, Oncopeltus famelicus 
F.: conspicuous black and orange bug. M. was not 
at all eager for this, but took it, pulled it about, bit 
its head off, and then had no more to do with it. 
Obs. 179. Sp. 88.—? Coccinellid, or allied family : 
a very highly polished, shining, black, hemispherical 
beetle, with two small red spots. It gave out yellow 
juice when handled. To my surprise M. ate this 
with no sign of distaste. 
Obs. 180. Sp. 89.—Carabid: small, dull-black 
ground-beetle like a Harpalus. M. also ate this. 
(Note.—Seeing how hungry for insects the monkey 
was, as evidenced by his eating the Carabid, his refusal 
of the Lycid is the more emphatic.) 
Series Aa. Jan. 13.—At 8 a.m., M. having had no insect 
food— 
Obs. 181. Sp. 86.—Lycid, Chlamydolycus trabeatus : 
as M. was hungry he pulled this beetle to pieces, and 
smelt each bit, but tasted none. 
Obs. 182. Sp. 44.— Pentatomid, Aspongopus 
viduatus ; shown to M. in a box. He looked at it 
for a very long time; the bug moved a little, and 
vibrated its short antennae very rapidly, and M. turned 
away from it. I brought it to his notice again, and 
he pawed it a little: just as | was taking it away for
