“ The colours of this insect are unusually sombre, and present a striking contrast to the gaudy tints by which the majority of these gay creatures are ornamented; it is so far remarkable, but it is more interesting to the entomologist, as being an unpublished addition to this genus. It was discovered in Java by Dr. Horsfield; and the drawing was made from an unique specimen which I observed while engaged in a long and laborious arrangement of the Linnæan Papilionidæ, (as they now appear at the India House,) collected by that zealous naturalist for the India Company. ”
