‘P80 INSECTA, 
filiform antenne *. In these two subgenera the inferior palpi hardly 
reach above the clypeus, and their second joint is scarcely twice as 
long as the first. 
In the two following subgenera, where the wings resemble those of 
the preceding subgenus, but are usually narrower and more elongated, 
and where the abdomen is also proportionally longer than that of 
most of the preceding ones, that joint is much lunger than the first, 
and its extremity evidently extends beyond the clypeus. In the Heli- 
conii—H evicontvus, Lat.; Mechanitis, Fab.; P. peliconit, Lin.—the 
antenne are twice the length of the head and thorax, and insensibly 
enlarged towards the extremity +. -Those of the Acree—Acrma, 
Fab.—are shortly and abruptly globuliform f. 
Sometimes—P. nymphalis, L.—the two anterior legs are strongly 
folded, either apparent and very hairy, or small and concealed. The 
inferior wings, of which the central cell is open in several, evidently 
embrace the abdomen beneath. The inferior palpi are proportion- 
ally longer, and frequently thicker and more approximated. 
Here, the central cell of the inferior wing is open. 
Those in which the inferior palpi are but slightly compressed, 
distant throughout their length, or at least at their extremity, and 
abruptly terminated by a slender and acicular joint; where the under 
surface of the wings frequently presents silvery or yellow spots on a 
fulvous ground; and the caterpillars of which are alway covered 
with spines or fleshy and hairy tubercles, compose the subgenera 
‘CeruosiA, Fab., and Areynnis, Meutira@a, Fab. In the first, several 
species of which have elevated and elongated wings, the inferior 
palpi are distant throughout their whole length, the hooks of the tarsi 
are simple, and the club of the antenne is oblong §. In the second 
it is short and abrupt; the hooks of the tarsi are unidentated, and the 
inferior palpi are only distant at their extremity. The inferior wings 
are frequently round. 
Some—Argynnis—Fab.—have nacred spots on the under part of 
their wings. Their caterpillars are furnished with spines, two on 
the neck longer than the rest. Those of the others—Melitea, Fab.— 
have little hairy tubercles; the wings are spotted like a chess-board, 
and the nacre is replaced by yellow, a circumstance which sometimes 
occurs in the preceding cnes ||. 
Those in which the inferior palpi are contiguous throughout their 
whole length, terminated almost insensibly in a point, and strongly 
compressed, form five other subgenera. 
Vanessa, Fab. 
The Vanesse are removed from the following ones by their an- 
tenn, abruptly terminated by a short turbinated or ovoid button. 
Their caterpillars are densely spinous.
