the Relative Edibility of Insects. 87 
Series w. Obs. 8692901. March 25. At 2 p.m. M, very 
hungry for insects. 
Obs. 874. Sp. 382.—Asilid: a fly of which the 9 
has a strong resemblance to a small brown bee; the 3 
is black. I offered M. a 3, which he took from the 
forceps and ate without hesitation: I then offered 
the bee-like 9, which M, took and hurriedly bit, as if 
he was afraid of it; he then looked at it m surprise 
and ate the rest of it in a more leisurely manner. 
(Note.—It was very difficult to avoid the conclusion 
that the monkey thought the Q fly was something else 
than it was. He had eaten the $ without hesitation, 
and after he had found the 9 innocuous, he ate it 
also. It appears to be a case of Batesian mimicry.) 
Serves v. Obs. 902-914. March 28. At 10.30 a.m. My 
squealing with eagerness. 
Obs. 913. Sp. 391.—? Clerid: a beautiful mimic 
of a Mutilla, about $-inch long, rather cylindrical in 
shape; dull red anteriorly, black with white marks 
posteriorly. The beetle has short antennae, which it 
vibrates rapidly, exactly as does a Mutulla. 
I found it on the tip of a grass stem. When it was 
put on the ground in front of M,, he treated it exactly 
as he and M, had treated Mutillids, and at once pawed 
it on the ground, throwing it about. I then tried to 
get it again for record, but the monkey seized it and 
very quickly put it into his mouth and crunched it 
up rapidly, as he would a Mutilla. But he afterwards 
spat it out again. The resemblance therefore seems 
to be synaposematic. After this experiment M, ate 
8 weevils (Lsaniis sp.).
