were not close together. After I had seen this specimen 
at rest I twice thought that bits of twisted dead leaves 
on other bushes were butterflies of this species.” I may 
add that when the Lycaenid is flitting about and settles 
temporarily this attitude is not adopted ; the tails then 
project backwards, and the antennae upwards as is usual.

General remarks on the PIERIDAE. 
On the whole the monkey seemed to find them not un- 
pleasant, but was rather doubtful about No. 170, the only 
aposematic speciés offered. The same doubt was mani- 
fested towards the most procryptic of all (No. 264) and 
its near relation 174. It must be remembered that, as 
with other butterflies, the classification of their coloration 
is founded upon the wnder surfaces of the wings. 
No. 170 is very conspicuous on the wing, and when the 
butterfly is drinking from mud the orange-red flush at 
base of hind-wing offers an easily recognisable mark; the 
*mud-drinker’s aposeme.”’ 
The apparent slight distastefulness of the highly pro- 
cryptic 264 is rather unexpected. 
The Pierines generally become much more procryptic in 
the dry season, when the under surface acquires a suffusion 
with pinkish, brown, or grey scales, causing them to harmon- 
ise admirably with the tints of the dried grass among 
which they settle.
