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. [Illustration: PLATE 9. _1. Euplœa Limniace._ E.

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. PLATE IX. Fig. 2. Danais Plexippe, _Godart_.--Pap. Plexippus, _Linn., Fabr._--Pap.
