the Relative Edibility of Insects. 49 
Series Bm. Obs. 596-611. Feb. 5—At 1.30 p.m., M. had 
had food, but was very hungry for insects. __ 
He ate 12 grasshoppers and some other insects, 
refusing others. 
Obs. 606. Sp. 286 a.—Danaida chrysippus : the typic- 
ally aposematic orange-brown butterfly with black wing 
tip enclosing a white bar. M. seized it very eagerly, 
then looked at it for a long time, pulled off the wings, 
and ate the body. 
Obs. 607. Sp. 287.—Hypsid, Argina amanda Bd. : 
a medium-sized, bright orange moth speckled with 
black. The wings of one side were cut off and the 
moth put on the “ground, M. looked well at this, put 
the body into his mouth, pulled it out, put ib in and 
pulled it out again, and finally discarded it. 
(Note.—His refusal of this aposematic moth is made 
more emphatic by his having been hungry enough to 
eat the distasteful D. chrysippus.) 
Obs. 608. Sp. 170.—Pierid, Mylothris agathina: M. 
was not at all eager to take this butterfly from my 
fingers, but ate it ‘without definite sign of dislike. 
Obs. 609. Sp. 286 B.—Danaida chry ysippus, form do- 
rippus Klug: the variety without black-and- white 
wing tips. M. took it and pulled off the wings, then 
ran about with the body for some time before “putting 
it into his mouth and eating it. After this two 
medium-sized and one large grasshopper were eaten. 
Series Bn. Obs. 612-615. Feb. 5.—These were the last 
observations made with M., for his owner took him 
back. 
SECTION II. 
Iw this section an attempt will be made to diagnose the 
degree of edibility of each species used in the experiments 
(including those of which details are omitted), grouping the 
species in their proper genera and families. 
I propose to use letters to denote the significance of the 
colours and habits of the insects, and the 1 signs +, —, or 
+ to denote their edibility. 
It must be constantly borne in mind here that I am only 
speaking of edibility to the monkey which was used as the 
test: to another animal, or a bird, the insects might be 
more, or less, edible.
