to this Papilio that unless the good wife overhauls
it at frequent intervals it would very soon be
destroyed.
18. PAPILIO CRESPHONTES (Cram).
 Only found in the south at Punta Gorda and at
San Pedro on the Sarstoon River.
19. PAPILIO THRASON (Feld).
 This is a sub-species of Papilio pfaon (Bois),
and it occurs, but not very commonly, in the
Western District.
20. PAPILIO MARCHANDI (Bois).
 The only locality that I have ever met with this
butterfly in the Colony is San Pedro on the
Sarstoon River in the extreme south. Here in
the month of August I was delighted to find it,
but not at all abundantly. It is very rapid on
the wing and the only way to capture it is to wait
until the insect settles to rest and feed. The
moist sand at the edge of the river and the muddy
edges of puddles of water in the roads were
favourite gathering places, and there I was able
to make my captures.
 When thus employed in drinking, these insects-
like all the Papilios-keep their wings in a per-
petual quiver, and they take the greatest care
not to soil or wet them. They, as it were, stand
on tiptoe ready at the slightest alarm to take flight.
