Aegiale Streckeri, n. sp., ♂.—Expands from2¼ inches to 3 inches. Upper side.—Superiors rich brown, but not as bright, nor has the brown as much red in it, as in yuccœ. There are three sub-apical costal white spots; a lemon-yellow spot at end of cell; there is a row of five yellow spots running across the wing, parallel with the exterior margin; the upper two are small and square in shape; the lowe three are small and triangular, and there is one in each of the three median interspaces. The inferiors have a yellow marginal border about 1/8 inch in width, the wing being otherwise immaculate, and is clothed with long, silky brown hair. Under side.—Superiors have the spots repeated. Inferiors are gray with a varying number of small white spots—one specimen having two and the other five. The female is larger and has the same number of spots as the male; the three sub-apical spots are white and the remainder yellow; in the female the five spots on the wing are in two series, the two upper being nearer the exterior margin, and the three lower are nearer the base; in the other words, they do not form a continuous line as in the male. This species has been confounded, in collections, with cofaqui, Strecker, which was described froma female. The male of cofaqui, is marked practically like the female, but the male has the long hair on the inferiors as in the new species.
