Euptoieta Claudia, from Miles City, showing upper and lower surfaces. Butterfly—Expanse of wings from to inches, 45-70 mm. Upper side of both wings fulvous or dull ferruginous, darker toward the base, crossed by an irregular black median line, which is darker, broader, and more zigzag on the fore wing than on the hind wing.

Beyond the middle they are whitish, shading off into the same brown as the base, with more or less whitish along the margin, the anal portion of the outer half being nearly as dark as the base, while the costal portion is almost white.
