52 Dr. G. D. H. Carpenter’s Experiments on 
General remarks on the BLATTIDAE. 
This monkey seemed to agree with the human estimate 
of cockroaches as disgusting insects! Obs. 161 is unique, 
and one is almost forced to believe it was not a cockroach 
that the monkey ate so eagerly. The notes omitted show 
that I did not see the insect until it was nearly consumed. 
The colours of the above Blattids do not fall into the scheme 
of classification adopted. The brightest-coloured light 
yellow species are just as timorous and light-shy as the 
darker species.

General remarks on the MANTIDAE. 
All the above were extremely procryptic except the very 
young, No. 33; these small black specimens were some- 
what ant-like. But when they are too large for this re- 
semblance, Mantidae, so far as I am aware, are the most 
generally cryptic of any family of insects, and, young 
and old, were eaten with greed. Also the large and con- 
spicuous white egg-capsules of No. 19 were eaten and 
sought out greedily. (See Series O, P, Q, X, Ab, Ac, 
Af, Ak.) Many Mantidae are known to take up a de- 
fensive or “ terrifying’ attitude when threatened, accom- 
panied with a noise produced in a special way, and I was 
able to see this adopted on several occasions by No. 19, 
and on the first occasion it seemed to cause the monkey 
to leave the mantis alone. (See Obs. 26, 95, 194.)
