Melit.ea picta, nov. sp. 



Male. Expands lyL inch. Upper side black with fulvous and 

 whitish spots as in M. pratemis Behr. 



Under side of primaries mottled with pale yellow, black and fulvous : 

 the apical third being yellow, interrupted by a black wedge-shaped 

 spot from the costa, and terminated by a curved black bar that extends 

 from the costa to the middle of the disk, and is there connected by a 

 small spot to a large black patch upon the middle of the inner margin ; 

 this last is edged without by yellow ; another black patch at the inner 

 angle 'extends so as nearly to connect with the wedge-shaped spot; a 

 faint yellow bar crosses the cell ; costa at base yellow ; rest of the disk 

 bright fulvous. 



Secondaries same yellow with no markings except two small brown 

 patches on hind margin, the one nearest anal angle distinct, the other 

 nearly obsolete, two small spots on costa and one or two dots near 

 the arc. 



Body above black, below yellow. 



From six specimens taken by Mr. Ridings in Nebraska Territory. 

 This may be readily distinguished from allied species, by the yellow 

 secondaries. 



Satyrus Ridingsii, nov. sp. 



Female. Expands 1 T 7 inch. Color grey brown ; both wings have 

 a submarginal series of stripes or oval spots of soiled white, varying in 

 shape iu individuals, sometimes connected so as to form a continuous 

 band; within two of these spots on primaries are round black ocelli 

 with minute white pupils ; no ocelli upon secondaries. 



Under side grey white mottled and streaked with fine brown spots 

 and lines ; a broad dentated band of a darker shade crosses the disk of 

 secondaries, edged without by whitish; a submarginal dentated line 

 corresponds to the outer edge of the band on upper surface ; primaries 

 have the spots and ocelli repeated; fringes alternate brown and grey.
