palpi in Pavonia, Morpho, and the other preceding subgenera, is 
tolerably wide; these palpi are not strongly compressed, as is the 
case in Satyrus, a subgenus very analogous to the two preceding ones. 
In the following subgenera the discoidal cell of the inferior wings 
is also closed posteriorly. 
Brassous, Fab., 
Where the antenne are abruptly terminated by a thickened obconical 
club, and the inferior palpi are short and do not extend beyond the 
clypeus. Near the inner margin of the inferior wings of the males 
is a longitudinal fissure covered with hairs *, 
Eumenira, Godart, 
Where the inferior palpi are longer, and where the antenne, at a 
short distance from their origin, become gradually thicker, and form 
an extremely elongated club +. The 
Euryzia, Jliq., 
Approaches Brassolis in the shortness of the inferior palpi; but they 
are proportionally thicker, and the club of the antennz is fusiform, 
elongated, and slightly curved }. 
Satyrus, Lat., 
Where the inferior palpi, as usual, extend beyond the clypeus, are 
strongly compressed, and have a sharp, densely pilose edge; where 
the antennz 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 §. 
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 chry- 
salides are short, contracted, smooth, and always fixed by a silken 
band that traverses the body, like those of Papilio proper, the Pie- 
rides, &c.||

Godart had lost their antenne. M. Poé has sent me some that are perfectly entire, 
captured by him in Havana.

|| 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.
