This and several of the following genera may be readily distinguished from any of the preceding by having the anterior legs, in both sexes, short and imperfect, the tarsi not being distinguishable into five joints, but generally consisting of a single piece with several crowded spines at the extremity. In the present genus there is a slight indication of an articulated structure, but very indistinct, and there are scarcely any projecting points in the room of claws. The antennÆ, which are placed very close to each other at the base, terminate in a pretty thick club elongated and somewhat curved. The palpi, which stand considerably apart from each other, are short, not rising above the head, densely clothed with hair-like scales which completely conceal the joints: of the latter the terminal one is minute and globular ending in a point, the second long and thick, the radical one about one-third its length. Outline of the upper wings triangular: claws simple. Chrysalis suspended by the tail, and never supported by a band round the middle.

EUPLŒA LIMNIACE.
PLATE IX. Fig. 1.

Danais Limniace, Godart.—Pap. Limniace, Cramer, Pl. 59, fig. D, E.—Pap. Similis, Fabr.

Expands nearly four inches; surface of the wings deep black, entirely covered with stripes and spots of shining light green, more or less mixed with white: towards the base of the wings the green colour is arranged in longitudinal stripes, externally in rounded spots, becoming smaller at the hinder margin where they form a regular row. The design on the under side is similar, but the ground colour of the under wings and a large space at the apex of the upper are pale brown, and the green marks are usually pale; the sinuosities fringed with white, the projections on the margin of the hinder wings forming a pretty acute angle; thorax and breast black, with numerous white points; abdomen yellowish beneath.

Rather extensively distributed over the eastern countries of Asia, and the adjacent islands.

EUPLŒA PLEXIPPE.

Danais Plexippe, Godart.—Pap. Plexippus, Linn., Fabr.—Pap. Genutia, Cramer, Pl. 206, fig. C, D.

This insect affords an example of a pretty extensive and beautiful group which is strikingly characterised by the prevalence of a peculiar colour and uniformity of design in the markings. The ground colour is a rich chestnut-brown, varying considerably in the intensity of the shade, the wings widely margined on the outside with black, more or less interrupted with white spots; the black colour sometimes running along the nervures in a broad stripe. They are common both to the old and new world, and many of them are very abundant. E. Plexippe occurs in the East Indies and China, also in the islands of Java, Ceylon, &c. and often appears in great plenty The colour is light chestnut-brown, approaching to fulvous, the whole external border of the wings with a broad black band, dilated at the apex of the superior pair so as to occupy the whole angle; this band bears two rows of small unequal white spots, and the black space at the summit of the upper wings has a broad oblique band of pure white, angular on the edges, and formed by the confluence of five spots; between this and the middle of the costa is a small group of white spots: all the nervures black and dilated. The under side differs in having the space between the white patch at the apex of the upper wings and the external margin ashy-brown; in having the ground colour of the inferior-wings pale fulvous, and the nervures of the same wings narrowly edged with white. The abdomen is nearly of the same colour as the wings; the thorax, breast, and head black, punctured with white; antennÆ black, the extremity of the club rust-red.
