Wings black, with violet, purple, and green reflections; upper with a longitudinal line, broken by the black of the wing near the base, the other part extending to the tip of the wing, sinuated anteriorly, and elbowed posteriorly; near the posterior margin are two irregular white spots, the upper sub-triangular, the under squareish; on the apical margin are seven whiteish spots, the first very minute, the second largest, the others gradually diminishing towards the long white line where they terminate. The fringe is black, slightly greyish on the edge; the underside of the wing is greyish at the base, and on the inner edge, then violet, the apical portion being of a silky yellowish brown; the lower wings are purplish violet, the outer margin at the base is whitish, the fringe is black at the base, at the end white--the white forming a broader line than the black; beneath it is violet black, and black with a greenish tinge. The thorax and body in the specimen described is rubbed; the latter seems to be blackish green, banded with white. I have seen a species closely resembling the above in Dr. Boisduval's immense collection. Habitat King George's Sound. Captain George Grey.* (*Footnote. The Saturnia laplacei, described and figured by the Baron Feisthamel in his description of the Lepidoptera collected on the voyage of the Favorite is synonymous with the Chelepteryx collesi, described by Mr. G.R. Gray in the First Volume of the Transactions of the Entomological Society of London page 122.) Odonestis elizabetha, new species.
