simply dentated. It has been observed that the nerves of the supe- 
rior ones are strongly inflated at their origin(1). 
Nympuatis, Lat. 
Similar to Biblis in the legs, but with shorter inferior palpi. It 
is only by the elongation of the club of the antennz that this sub- 
genus is distinguished from Vanessa. The caterpillars, however, 
are different; independently of their having but few spines or fleshy 
prominences, they are somewhat attenuated towards their posterior 
extremity, 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 
designated in small groups by amateurs, by the names of Syl- 
vains and Mars; the males of the latter are decorated with 
changeable colours. 'To this subgenus belongs another beauti- 
ful species, also indigenous to France, called the Jason—Papilio 
Jason, L. The form and size of the club of the antennz vary a 
little, as well as the relative proportions of the wings; this has 
caused the formation of some other subgenera, but their charac- 
ters are very equivocal. The species which approximate most 
to Biblis, one of which is the Sylvain ceenobite of Engrammelle, 
form the genus Nep/is of Fabricius. Of those which are most 
removed from the preceding ones either by their antennz or the 
inferior wings, and which present tails like certain species of 
the Equites of Linnzus, we will mention the Jason already 
quoted(2). 
Morpruo, Fab. 
Differing from Nymphalis in the almost filiform antennz, slightly 
and gradually enlarged towards the extremity. 
All the species are peculiar to South America, and are re- 
markable for their size, colours, and the ocellated spots on the 
inferior surface of their wings. Linnzus placed several of them 
among his Greeks(3).
