Genus Argynnis 
Butterfly .— The male is fulvous upon the upper side, all the 
dark markings being heavy and black, and the basal areas of the 
wings clouded with fuscous, this dark clouding on the hind 
wings reaching down and nearly covering the inner angle. The 
fore wings on the under side are buff, laved with pale red at the 
base, marked with ferruginous on the outer margin and about 
the subapical spots. The submarginal and subapical spots are 
silvered, especially the latter. The hind wings are deep ferrugi¬ 
nous, mottled with buff. The submarginal band is buff, narrow, 
and dusted with more or less ferruginous. All the spots are well 
silvered. The female has the basal area of the fore wings bright 
pinkish-fulvous, and the belt of the secondaries almost lost in the 
deep ground-color.
