NOTES ON THE BUTTERFLIES

2. PAPILIO POLYDAMAS (Linn).
 This is a common butterfly and the most com-
mon of all the Papilios. It is frequently observed
in gardens and I have found the larvae in companies
of a dozen and upwards on a climbing plant in
my garden. This insect is exceedingly tenacious
of life, and an ordinary nip on the thorax that
would be sufficient to kill most butterflies does not
appear to inconvenience it in the least.
3. PAPILIO ZESTOS (Gray).
 This beautiful insect, which is a sub-species of
Papilio sesostris (Cram), is generally distributed
throughout the Colony, but it is nowhere abun-
dant. Its flight is rapid and strong and it is fond
of coursing up and down forest roads settling at
times on the roadside bushes. I have met with
it in the northern districts but it is much more
frequently seen in the south of the Colony. It
is not attracted by wet sand or mud which is so
enticing to many others of the family, but it
prefers to visit flowering shrubs.
4. PAPILIO SALVINI (Bates).
 I have only met with this insect in the Western
District at the Cayo and at Benque Viejo. I have
never found it anywhere except resting on moist
