The Large Metal-Mark

Calephelis borealis (Cal-e-phe'lis bo-re-a'lis) The upper surface of the wings is dull brownish yellow, crossed by obscure, transverse stripes; on the outer half of the wings are two lead-colored lines, with a row of black dots between them. The under surface is of a rather dark and pale orange; paler and duller next the base, marked with transverse black lines and dots, and transverse series of steel-colored spots. Expanse of wings one to one and one-fourth inches. The early stages are unknown. The butterfly is very rare in our territory; it has been taken in New York, New Jersey, West Virginia, Michigan, and Illinois.
