There are a few other species of this genus found within the limits of the United States, but enough have been represented to give a clear conception of the characteristics of the group, which is widely distributed throughout the world.
Genus SYSTASEA, Butler
Butterfly.—The palpi are porrect, the third joint projecting forward, the second joint densely scaled below. The antennæ are slender, the club moderately stout, somewhat bluntly pointed, bent, not hooked. The hind wings are somewhat crenulate, and deeply excised opposite the end of the cell. The fifth vein is lacking. In the fore wing the lower radial arises from a point nearer the upper radial than the third median nervule. The fore wings are crossed about the middle by translucent spots or bands.
