Butterfly.—This little species, the upper side of which in both sexes is correctly shown in the plate, has the under side of the wings dark brown, with the light spots of the upper side greatly enlarged, especially upon the disks of the wings, fused, and pale yellow, thus contrasting strongly with the rest of the wings. Expanse, ♂, 1.00 inch; ♁, 1.25 inch.

Early Stages.—These are not thoroughly known as yet. The larva feeds on grasses.

Peck's Skipper ranges from Canada southward to Virginia, and west to Kansas and Iowa.
