This species has been taken in the two widely separated counties of 

 Vanderburgh (Evans) and Lake, but nowhere else in the State. As to 

 its distinguishing characters, I quote the following from Edwards, loc. 

 cit. : "Atlantis is readily distinguished from Aphrodite by its smaller 

 size, duller color, broad black margins, confluent median band of sec- 

 ondaries and color of same wings below ; also, by the longer and nar- 

 rower fore wings. It is rarely to be seen iu the open country where 

 Aphrodite abounds, but frequents narrow passes in the mountains and 

 the grass fields which skirt the forests. It is readily attracted by any 

 decaying animal matter, and a piece of meat or a dead bird or snake 

 has irresistible charms for it." 



28. (141.) ARGYNNIS MYRINA, Cram. Myrina Butterfly. The Silver- 



Bordered Fritillary.

Vanderburgh County, by Evans. Otherwise only from the northern 

 half of the State, where it is quite frequent in meadows and prairies 

 from June 15 to September. Food plant, violets. 



29. (152.) ARGYNNIS BELI.ONA, Fab. Belloua 'Butterfly. The 



Meadow Fritillary.

 Brenthis bellona, Scudder, But. E. U. S. and Can., 1889, I, 608; 



III, pis. 5, 12, 22, 64, 75, 84. 



This, the smallest member of the genus, is found throughout the east- 

 ern and northern parts of the State, but is very rare if it occurs at all in 

 the Lower Wabash Valley. It is quite common, where found, during 

 July and August, in low meadows and prairies, especially those contain- 

 ing many flowers.
