Where the inferior palpi are very short, scarcely reaching the 
clypeus with their superior extremity, and their third joint is in- 
distinct. 
The caterpillars, when alarmed, protrude from the superior part 
of their neck a soft, forked horn, that usually diffuses a penetrating 
and disagreeable odour. Their skin is naked. The chrysalis is 
attached with a silken band, and exposed. 
The species of this subgenus are remarkable for their size and 
varied colouring. They are more particularly abundant in the 
tropical countries of both hemispheres. Those with red spots on the 
breast form the division of the Equites Troes or Trojan Knights of 
Linnzeus. Those which are destitute of these marks in that place, 
he styles Achivi or Greeks. ‘The inferior wings of several are pro- 
longed into a sort of tail. Such is the

The caterpillar is green with black rings dotted with red. It 
feeds on the leaves of the carrot, fennel, &c. 
Two other tailed Papilios are found in France, the P. poda-

This subgenus only differs from Papilio proper in the club of the 
antenn, which is shorter and more rounded. ; 
I know two species, one from Senegal, the other from Gui- 
nea, both of which are in the splended collection of Count De-

Parnassius, Lat.—Donriris, Fab., 
Where the inferior palpi evidently extend above the clypeus, taper 
to a point, and are distinctly triarticulated. The terminal button of 
their antennz is short, almost ovoid and straight. The females have 
a kind of cornecus boat-shaped sac at the posterior extremity of 
their abdomen. 
The caterpillars also have a retractile tentaculum in the neck, like 
those of the true Papilio, but the cocoon in which they become chry- 
salides is formed of leaves connected by filaments of silk, 
The species are exclusively proper to the Alpine and sub- 
alpine regions of Europe and the north of Asia. Such for in-
