184 INSECTA. 
Satyrus, Lat. 
Where the inferior palpi, as usual, extend beyond the clypeus, are 
strongly compressed, and have a sharp, densely pilose edge; where 
the antenne are terminated by a little globuliform inflation, or an 
elongated and slender club. Godart has remarked that the two or 
three first nervures of the superior wings are strongly inflated at their 
origin. 
The caterpillars are naked, or nearly so, and the posterior extre- 
mity of their body is narrowed into a forked point. The chrysalides 
are bifid anteriorly, and present dorsal tubercles(1). 
We will terminate this first section of the Diurnal Lepidoptera 
with those in which the inferior palpi have three distinct joints, but 
the last almost naked, or much less thickly covered with scales than 
the preceding ones, and where the hooks of the tarsi are very small, 
and not at all, or scarcely, salient. The discoidal cell of the inferior 
wings is open posteriorly. 
Their caterpillars are oval, or have the form of Onisci. The 
chrysalides are short, contracted, smooth, and always fixed bya 
silken band that traverses the body, like those of Papilio proper, the 
Pierides, &c.(2) 
Linnzus placed them among his Plebei, in the division of the Ru- 
ricole, and Fabricius—Entom. Syst.—in a homonymous section of 
his Hesperiz. They form the genus 4rgus of M. de Lamarck. Fa- 
bricius ultimately—Syst. Gloss.—divided it into several genera, the 
characters of which demand revision. 
Sometimes the antennz terminate, as usual, in a solid, globuliform, 
or clavate inflation. 
In some, or at least their males, the two anterior legs are much 
shorter than the others. They compose the subgenus 
Erycina, Lat., 
And are peculiar to America(3).

Satyre. : 
(2) According to this view of the subject, these subgenera ought to terminate 
this section, which should begin with Satyrus. Such was the arrangement we 
originally adopted.
