Northern Metal-mark
Butterfly.-Fully twice as large as the preceding species. The wings on the upper side are sooty-brown, spotted with black, and marked by a marginal and submarginal series of small metallic spots. On the under side the wings are light red, spotted with a multitude of small black spots arranged in regular series.
The two rows of metallic spots near the margins are repeated more distinctly on this side. Expanse, 1.15 inch.
Early Stages.-Unknown.
This rare insect has been taken from New York to Virginia, and as far west as Michigan and Illinois. The only specimen I have ever seen in life I took at the White Sulphur Springs in West Virginia. It settled on the under side of a twig of black birch, with expanded wings, just over my head, and by a lucky stroke of the net I swept it in.
