way toward the basal angle of the costal margin, curves slightly outward and fades away; the costal nervure, on approaching the border, curves outward and meets the border near the middle of its outer two-thirds; the subcostal breaks into three branches, exactly as in Zophoessa. The median nervure and its middle branch form a continuous, almost exactly straight line, from which the lowermost branch parts opposite the union of the vein closing the cell with the lowest subcostal nervule; and the uppermost at exactly the tip of the cell, or as far beyond the origin of the lowest nervule as the upper limit of the vein closing the cell is from the base of the upper subcostal nervule; the vein closing the cell is a very weak one and originates on the lowest subcostal nervule, as far from the second divarication of the subcostal nervure as that is from the first, and passes in a gentle curve, opening outward, to the second divarication of the median nervure. The submedian and internal nervures are united for a short distance beyond the base of the cell ; the submedian passes with a gentle regular curve to the outer border, at the lower outer angle; the internal parts from this with an opposing curve and terminates somewhere below the middle of the inner flap of the wing, probably approaching again the submedian nervure near its extremity. None of the veins are swollen at the base: The cell is two and three-quarters times longer than broad.
In the disposition of its markings (Pl. I, fig. 8) this genus does not seem to show any strong affinity with any living butterflies, although it has some features in common with the genera already referred to (Pl. II, figs. 3, 9, 11, 13, 14). The base of the wing is dark, followed by paler spots and bands, differing greatly in the front and hind wings, followed again by a belt of dusky scales, which separates from the rest of the wing a paler submarginal band, enclosing roundish, interspaceal, often pupillated spots of varying size, and whose outer limits are at least an interspace's distance from the outer border; the latter is margined, on the hind wings, with alternating darker and lighter hues. The middle portions of the two wings differ; the hind wings have simply a broad pale field, gradually merging on either side into the darker parts and varied by a cloudy, wavy, narrow, transverse belt near the middle; the fore wing, on the other hand, is
