PLATE II. Fig. 1.
_Linn. Fabr. Cramer_, 91, C.--Papilio Agenor, _Linn. Fabr. Cramer_, 32,
A, B.
The upper wings in this species expand about five inches; they are
blackish and marked with numerous longitudinal rays of a greyish-ash
colour, each of them having a large blood-red or ochrey-yellow
triangular patch at the base. The inferior wings are waved on the
hinder margin, and narrowly edged with white in the emarginations, the
disk almost entirely occupied by a broad white band divided by the dark
nervures, the hinder portion dusky with a series of deep-black spots
of an ovate or rounded form, that placed on the anal angle smaller
than the rest and encircled with fulvous, which colour extends to the
extremity of the internal border; on the under side they are spotted
with red or ochre-yellow at the base: body black, the prothorax marked
with several white points.
The above description applies to one of the female varieties of _P.
Memnon_, which was usually regarded as a distinct species and known by
the name of _Agenor_. Indeed it is so unlike the male, that authors
would probably never have thought of associating them, had they not
been reared from the same description of caterpillar. The male is
entirely without the basal red spot, and the dark ground colour has
a greenish reflection; the upper wings have a red or ochreous spot
at the base on the under side, and there are likewise four small red
marks on the same part of the inferior wings: the latter are deep black
anteriorly and cinereous behind; the cinereous portions containing two
rows of deep black rounded spots, that next the anal angle encircled
with yellow. _P. Androgeos_ of Cramer (pl. 91, A. B.) is a variety
of this sex, while the _P. Anceus_, and _P. Laomedon_, of the same
iconographist are varieties of the female.
The caterpillar, which feeds on the different kinds of _Citrus_, is
described by Dr. Horsfield as of a green colour, with an ocelliform
lateral mark on the third segment, and a transverse white band; a band
of pale green between the fourth and fifth segments, and an oblique
white stripe on the eighth and ninth; the anal segment likewise of
that colour. The anterior part of the body is considerably attenuated,
similar to what is observed in the caterpillars of many of the
Hawkmoths. Chrysalis green, reddish-yellow on the back.
This insect is found in China, and the islands of the Indian Ocean, and
is rather a common species.
