LEPIDOPTERA.

palpi in Pavonia, Morplio, 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. 



Brassolis, Fab., 

 Where the antennae 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*. 

 EuMENiA, Godart, 

 Where the inferior palpi are longer, and where the antennae, at a 

 short distance from their origin, become gradually thicker, and form 

 an extremely elongated club f. The 



EuRYBiA, Illig., 



Approaches Brassolis in the shortness of the inferior palpi ; but they 

 are proportionally thicker, and the club of the antennae is fusiform, 

 elongated, and slightly curved J. 



Satyrus, Lat., 

 Where the inferior palpi, as usual, extend beyond the clypeus, are 

 strongly compressed, and have a sharp, densely pilose edge; where 

 the antennae 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 Avith 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 antennae. M. Poe has sent me some that are perfectly entire, 

 captured by him in Havana.

II 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.
