Rh latter broad and transverse, never produced in front, with three ocelli on the crown, (Pl.

XVIII. Fig. 1.

head is black, with two minute buff-coloured spots over the insertion of the antennæ. The thorax is considerably broader than the head, and angulated on each side, near the middle, the colour black, with a narrow anterior and broad posterior margin of yellow. The remainder of the body is black, except the posterior margin of the basal segments of the abdomen, which are chestnut in the centre. The legs are black, with the thighs, except at the tip, scarlet. The general colour of the anterior wings is chocolate brown, darkest at the base, the anterior costa at the base, and the veins, of a rich golden yellow; the latter are divided, rather before the centre of the wing, by a curved transverse vein, thicker than the rest; from the base of the wing to this vein, the longitudinal veins are furcate, beyond it they are numerous, and form a great number of irregular shaped cells, (differing on the opposite wing,) and terminating in about twenty longitudinal veins, received by another vein which runs parallel with the exterior margin of the wing. The hinder wings are of a dull buff-ochre colour, paler next the body.
