282° INSECTA, 
and slightly curved at their extremity ; where the two anterior legs 
are short and folded in both sexes, and the antenne terminate in a 
much smaller club. The wings are also proportionally wider and 
simply dentated. It has been observed that the nerves of the supe- 
rior ones are strongly inflated at their origin *. 
Nympuatis, Lat., 
Similar to Biblis in the legs, but with shorter inferior palpi. It is 
only by the elongation of the club of the antennze that this subgenus 
is distinguished from Vanessa. ‘The caterpillars, however, are dif- 
ferent; independently of their having but few spines or fleshy promi- 
nences, they are somewhat attenuated towards their posterior extre- 
mity, which is slightly forked. 
These Lepidoptera are usually very highly ornamented, and their 
flight is elevated and rapid. 
Several beautiful species inhabit France. Such are those de- 
signated in small groups by amateurs, by the names of Sylvains 
and Mars; the males of the latter are decorated with changeable 
colours. To this subgenus belongs another beautiful species, 
also indigenous to France, called the Jason—Papilio Jason, L. 
The form and size ef the club of the antenne vary a little, as 
well as the relative proportions of the wings; this has caused the 
formation of some other subgenera, but their characters are very 
equivocal. The species which approximate most to Biblis, 
one of which is the Sylvain cenobite of Engrammelle, form the 
genus Neptis of Fabricius. Of those which are most removed 
from the preceding ones, either by their antenne or the inferior 
wings, and which present tails like certain species of the Equites 
of Linnzeus, we will mention the Jason already quoted +. 
Morpno, ab., 
Differing from Nymphalis in the almost filiform antenne, slightly 
and gradually enlarged towards the extremity. 
All the species are peculiar to South America, and are remark- 
able for their size, colours, and the ocellated spots on the inferior 
surface of their wings. Linnzus placed several of them among 
his Greeks ft. 
Godart has separated from them, by the generic name of 
Pavoni, 
Those species in which the central cell of the inferior wings is closed, 
and where the most internal nerve of the superior is curved into an 
S, instead of being straight or but slightly arcuated. A species pe- 
culiar to the East Indies, in which the anal angle of the inferior 
wings is extended in the manner of a tail, the P. phidippus, is the 
type of the genus Amaruusra of Fabricius. All the others are from 
the western continent. The edge of the second joint of the inferior
