Butterfly.—The upper side is correctly shown in the plate. On the under side the wings are pale yellow, with a few small, round spots on the margin and disk of the hind wings, a black patch at the base, large black marginal spots, and a central, interrupted, longitudinal black streak on the disk of the primaries. Expanse, 1.15-1.25 inch.
The insect ranges from Connecticut to Patagonia, over all the most habitable parts of the New World. I have taken it frequently in southern Indiana, where I often have collected in recent years.
Genus PRENES, Scudder
Butterfly.—The antennæ are short, not half the length of the costa. The head is broad, and the antennæ are inserted widely apart. The club is moderate, terminating in a fine point which is bent back at right angles, forming a distinct crook. The abdomen is long and slender, but does not project beyond the hind margin of the secondaries. The fore wings are pointed at the apex and are relatively longer and narrower than in the preceding genus. The neuration is illustrated in the cut.
Early Stages.—These have not yet been studied.

Butterfly.—Accurately depicted in the plate. The under side is like the upper side, but a shade paler. The under side of the abdomen is whitish. Expanse, 1.45-1.60 inch.
