autocles (R. and J.), but is a much more handsome
insect.
 The females are particularly rare, and I have
scarcely ever seen them.
22, PAPILIO MACROSILAUS (Gray).
 Found usually at the edges of rivers and mud
pools or puddles of water in the dry season
congregating with other butterflies. It is a
very beautiful and at the same time delicate
insect, the tail-like appendages are unusually
long and slender and are very liable to be
broken off when the butterfly is captured in the
net.
 I have taken it not uncommonly at the Cayo
and Benque Viejo in the west and at San Pedro
Sarstoon in the south.
23, PAPILIO AGESILAUS (Guer).
 Taken in the Western District, always on sand-
banks by the riverside in the dry season.
24. PAPILIO EPIDAUS (Doub).
 Taken at the same time and place as the pre-
ceding, but it is a more common insect. It greatly
resembles P. agesilaus.
 All these three butterflies, Macrosilaus, Agesilaus
and Epidaus have a great resemblance to each
other but Macrosilaus is a much larger and finer
insect.
