The Papilionidse, comprising many of the noblest and richest- 
colonred butterflies, and long placed at the head of the group, 
are almost as universally distributed as the Pieridse, but they do 
not extend to so many remote islands nor so far into the Arctic 
and Antarctic regions. Nine-tenths of the species belong to the 
genus PapiUo, and these are especially abundant in tropical 
regions, although species occur in every region and every sub- 
region. Well-marked sub-divisions of this large genus are 
characteristic of each great region— as the “iEneas” group in the 
Neotropical, the “Paris ” group in the Oriental, the “iEgeus” group 
in the Australian, the “ Zenobius ” group in the Ethiopian, and 
many others. The few species of the Palaearctic region belong, 
on the other hand, to a group of universal distribution, and the 
Nearetic has a good number of species allied to Neotropical 
forms. 
The other genera have mostly a very restricted range. Par- 
nassius is an Alpine genus, confined to the Palsearctic and 
Nearetic regions. The Palsearctic region further possesses 5 
peculiar genera — Mesapia, Sypermnestra , Poritis, Eericinus, and 
Thais; the Oriental has 4, Calinaga , Teinopalpus, BJmtanitis , 
and Leptocircus, the latter going as far as Celebes; the Aus- 
tralian has 1, Eurycus ; and the Neotropical 1, Euryades, con- 
fined to the Chilian sub-region. The Ethiopian and the Nearetic 
regions have no peculiar genera.
