limbal row of circular spots reduced to three. The spots and 
bands of black in discal and basal areas carried through from 
upper side. 
Under side ; Secondaries : Completely silvered. Groundcolor, 
creamy-buff, with a liberal mottling of brown in the basal two- 
thirds of wing. Fine double marginal band. The subarginal 
silver row of seven ovals, shaded internally by brown crescents. 
The discal and basal silvered spots shaded internally by fine 
black lines. 
Female, expanse 2 7/16 inches, 62 millimetres. 
Upper side; Primaries: Differ from male principally in the 
fact that the ground color is lighter and less uniform and the 
dark markings are not suppressed over the apical area. There 
is also a row of eight yellow-brown submarginal ovals, corre- 
sponding to a silvered row on the under surface. 
Upper side; Secondaries: Similar to male except for lighter 
and less uniform ground color. 
Under side; Primaries: Differ from male in having a well 
silvered submarginal row of spots, and in the richer red-brown of 
the basal half of wing. 
Under side; Secondaries: Same as male, except for a slightly 
greater amount of brown in the ground color of the basal two- 
thirds of wing. 
This species is related to montivaga, and may, of course turn 
out to be a geographic race of that species.
