have been noticed by the most casual observer, flitting with a 

 devious direction over the herbage, and on meeting with a com- 

 panion mounting aloft in the air, with a hurried and irregular 

 movement. Some species occasionally alight in great numbers 

 on moist places in roads. 



The caterpillar is destitute of the retractile teutacula of the 

 neck, and the chrysalis is of an angulated form, attached to a 

 fixed object a by thread passed around the body, the head being 

 upward.

Desc. The black terminal margin of the upper wings extends 

 along the costal margin nearly to the middle ; the black transverse 

 line on this pair of wings is very short, and consists of two cur- 

 vatures ; this curvilinear line appears also on the inferior surface, 

 which is yellow, very slightly tinged with fulvous on the disk, 

 with a blackish point at each indentation of the edge, and an 

 ovate bright fulvous spot near the base ; the black terminal mar- 

 gin of the inferior wings has a prominent undulation in the mid- 

 dle ', the inferior surface of this pair of wings is yellow, marked 

 by numerous brownish or ferruginous abbreviated transverse 

 lines, a minute black point in the centre of the wing, and two or 

 three more obvious, irregularly undulated, ferruginous, oblique 

 lines : head and thorax above, blackish : antennae blackish, be- 

 neath white, with black incisures : feet whitish : abdomen black, 

 each side with a yellow line : venter with yellow incisures. 



Ohs. It is said by Cramer to inhabit Virginia, but it is also 

 found in Pennsylvania, and in all the Southern States. It is 

 subject to some little variations ; the fine fulvous spot near the 

 base of the inferior surface of the upper wings, is sometimes 

 white, and the oblique lines under the inferior wings, difi'er in 

 width and distinctness.
