_Upper Side._ The wings are of a brown orange, having many black spots, of different sizes and shapes on them. A black scolloped border runs along the external edges of the posterior wings, whereon are two rows of tawny red spots, appearing like crescents, with their convex sides placed against each other. All the wings are scolloped or dentated. _Under Side._ The anterior wings, toward the body, are brown orange. The tips are of a yellowish flesh colour, with some olive spots on them, with black spots, as on the upper side. The posterior wings are of a yellow flesh colour, marked with some olive spots, and white marks, which seem of a silver hue. A margin of olive colour runs along the external edges, whereon is a row of flesh-coloured crescents (as on the upper side), with an intersected narrow line above them. Over these, are five round olive spots, of equal sizes, with a dot of silver in their centres. The specific name given to this species by Drury, having the priority in point of date, would have been retained, had it not been identical with that of the genus to which it belongs. Engramelle and several other authors have, inadvertently, given it as an inhabitant of the south of Europe. PLATE VII. [Illustration] NYCTALEMON PATROCLUS. Plate VII. fig. 1. (Upper Side).
