Male. — Expands 3 inches. 



Allied to Nohomis. Upper side bright fulvous, much obscured from base to 

 middle of disk, except upon a portion of the cell of primaries; both wings 

 bordered by two parallel black lines, which, on secondaries, enclose a rather 

 broad clear fulvous space, on primaries a narrow space cut by the black nervules; 

 anterior to the.se lines, on primaries, a series of black lanceolate spots, the an- 

 terior ones connected and touching the inner line ; on secondaries the spots are 

 lunular, separated, and do not toucli the line ; the extra-discal spots on primaries 

 are irregular in size and shape, rather sub-quadrate and lanceolate, on second- 

 aries minute ; the markings to base as in Nokomis, heavy on primaries, light on 

 secondaries, the discal band on the latter being broken into small, separate, -sub- 

 lunular spots ; fringes fulvous, on primaries black at tips of the nervules. 



Under side of primaries red from base to hind margin, and over whole wing 

 except a small area near apex, where it is bright ochre-yellow ; a brown patch 

 on middle of this area ; the black markings repeated ; the upper five sub- 

 marginal spots enclose silver, and there are three silver spots on the patch. 



Secondaries deep ferruginous-brown from base to the outer edge of the second 

 row of spots, between this and outer row a clear ochre-yellow space ; the hind niar' 

 gin same color as the disk, with an obscure appearance of fulvous between the 

 nervules ; all the spots well silvered ; the seven sub-marginal are narrow segments 

 of circles, and are edged broadly on anterior side by ferruginous-brown ; those 

 of the second row are rather small, mostly rounded, the one next inner margin 

 sub-lunate ; the third row consists of three large spots, the outer ones sub-lunate, 

 the other rounded, and edged on posterior side by black ; all the spots of the 

 two rows edged heavily on basal side by black ; in cell a round spot, and below
