an inch long, black, spiny. Offered on the leaf to 
which it was affixed conspicuously.- M, was much 
more interested in the leaf, but smelt, handled, nibbled 
the pupa and discarded it. 
(Note.—This observation is particularly interesting 
because, unhke M,, M, had previously eaten all the 
Cassidid beetles offered to him. This pupa belonged 
to a large species, probably 251.) 
Obs. 728. Sp. 334—Lymantrid, Arctornis (Hu- 
proctis) producta Wik.: a pure white moth with the 
black tip of the abdomen surrounded by yellow hairs 
as in our “ gold-tail.” Offered at rest in a box. 
M, looked very closely at it and licked a wing, whereat 
the moth protruded the tip of the abdomen dorsal- 
wards between the edges of the wings. M, again put 
his mouth close down, but I could not see whether he 
licked the moth again. He pawed it on the ground 
and left it. 
(Note—Compare the behaviour of the Zygaenid, 
Obs. 639.)

Series @. Obs. 766-787. March 10, at 2.30 p.m.: M, 
quite ready for insects. 
Obs. 766. Sp. 350.—Mantid: a young green speci- 
men. It was offered to M,, who to my intense surprise 
looked at it as if not knowing what it was. He then 
pulled it about, tasted it, and left it. Afterwards he 
came back to it and ate the pieces. 
(Note.—It is likely that this was the first mantis 
that this young monkey had ever seen, for he had 
been a captive from extreme babyhood. It is worth 
comparing this observation with 26, when M, first 
met the big mantis of which he subsequently ate 
numbers.) 
Obs. 774. Sp. 351.—Noctuid larva: a leaf-green, 
extremely procryptic caterpillar. M, took it and 
held it wriggling in his hand for a long while. | I feel 
quite sure he had not seen one before, as I had never 
taken caterpillars to him. He then bit off half and 
ate it with great satisfaction, afterwards eating the 
rest and licking up from off the ground a large drop 
of the visceral contents which had exuded. 
Obs. 782. Sp. 357.—Chrysomelid: a small, com- 
pact, inconspicuous brown and black beetle, but it
