the simple contrast of blackish and pale orange 

 colours, of its superior surface, as well as by the 

 rows of slender silvery lines which decorate the 

 under page of its inferior wings. 



I have taken this insect in Georgia, East Flo- 

 rida, Arkansaw, and Missouri, but have not yet 

 met with it in Pennsylvania. Cramer described 

 his specimen, in the collection of Mr. J. C. Syl- 

 vius Van Lennep, and states it to have been 

 taken in Virginia. He has applied to it the ter- 

 restrial name of the daughter of Jupiter and 

 Latona, and the twin sister of Apollo, in pursu- 

 ance of the example of Linne, who thus endea- 

 voured to connect Entomology with Mythology 

 and the civil history of antiquity. 



The plate represents two views of this species, 

 beneath which is an enlarged palpus.
