The experiments were carried out, and records made, 
in precisely the same manner as described in the M, series 
of experiments. A total number of 131 species were used 
for M,, of which 55 had been previously tested on M,. 
These latter therefore were doubly tested, and a table at 
the end of the paper, comparing the treatment of the two 
monkeys, brings out some interesting points of difference. 
Series a. Obs. 616—619. Feb. 6. 
Obs. 616. Sp. 44.—Pentatomid, probably Aspongo- 
pus viduatus : a large dark brown bug. When it flies 
it exposes the red .upper surface of the abdomen. 
It was offered in a box with a specimen of the Tene- 
brionid beetle Macropoda transversalis, and was taken 
out in preference to the beetle. M, examined it very 
attentively, bit off and ate the head and thorax, 
then pulled open the tegmina and wings so that the 
red abdomen was exposed, and then dropped the 
insect, which gave out the typical rank “ bug ” odour. 
Obs. 617. Sp. 13.—The Tenebrionid beetle was 
picked up, bitten, and dropped. 
Series 8. Obs. 620-637. Feb. 7—At 11 a.m., M, very 
hungry. 
Obs. 620. Sp. 67.—Asilid, Hoplistomerus serripes : 
M, appeared to be deceived by the Hymenopteroid 
appearance of this fly : he looked at it very suspiciously, 
took it up gingerly, and put it down. As he was not 
stung he took it up again, re-examined it, bit off its 
head and finally ate the fly with appreciation. 
(Note-—The behaviour of the monkey was most 
interesting and very strongly suggested that this fly 
is a true Batesian mimic, 7. e. pseudaposematic and 
edible.) 
Series y. Obs. 638-651. Feb. 7.—At 5 p.m. M, was quite 
ready for more insects. 
Obs. 638. Sp. 186.—Six staple grasshoppers 
(Catantops decoratus) eaten greedily. 
Obs. 639. Sp. 262.—Zygaenid, Neurosymploca 
ranthosoma: this moth was offered in the lid of a 
chip box. M, smelt it once, then for a time paid no 
more attention to it. As I still held it out to him he 
put out a hand and touched it. The Zygaenid lifted 
its wings so as to expose the bright yellow abdomen, 
hitherto concealed. M, would then have nothing 
more to do with the moth.
