specimens but luck was against me for I found
no larvae of any sort on it.
 The butterfly is quite rare and the female
particularly so. I know of no other record of its
capture anywhere in the Colony.

 The members of the Papilio family that are
most frequently seen are Capys, Philolaus, Poly-
damas, Phaon and Autocles.
 The red and black Papilios, of which there are
quite a number, are a difficult class and identifica-
tion of some of these is not always easy.
 Some of the Papilios, as Autocles, have short
and broad tails to the underwings; some, as
Capys, have no tails at all; and some again have
these ,appendages unusually long and slender as
in the Macrosilaus group.
 All the Papilio larvae that I have seen live on
plants which contain a volatile odorous oil such
as orange and rue, and from these food plants
they appear to secrete a material for defence
purposes. When danger threatens they extrude
from two receptacles situated at the back of the
neck a pair of orange-coloured processes, and at
the same time the atmosphere becomes filled with
a pungent odour resembling that of the oil found
in the food plant.
 It will be observed that Papilio erostratus
 (Westw) is not included in the above list. Dr.
