q. Eurypylus-group. Hind wings elongate or tailed.
Genus LEPTOCIRCUS.
Making, in all, twenty distinct groups of Malayan
Papilionidse.
The first section of the genus Papilio (A) comprises
insects which, though differing considerably in structure, having much general resemblance. They all have
a weak, low flight, frequent the most luxuriant forestdistricts, seem to love the shade, and are the objects
of mimicry by other Papilios.
Section B consists of weak-bodied, large-winged insects, with an irregular wavering flight, and which,
when resting on foliage, often expand the wings, which
the species of the other sections rarely or never do.
They are the most conspicuous and striking of eastern
Butterflies.
Section C consists of much weaker and slower-flying
insects, often resembling in their flight, as well as in
their colours, species of Danaidae.
