A section of Pieris has lately been established as a genus under the above name, founded, however, on characters not of a very decided description. The most important one perhaps is the shape of the chrysalis, which is boat-shaped, or equally attenuated to both extremities, somewhat arched, and without lateral points. The antennÆ of the perfect insect are short, with the articulations distinctly marked, the club rather abrupt and forming an ovoid compressed mass. The common British species Mancipium Cardamines is referred to it, and this insect may be regarded as a characteristic example of the kinds which it includes. Like the Orange-tip, the majority have a patch of bright red on the tips of the anterior wings, and the under side of the posterior is often beautifully marked with green and pearl white. Several other species, besides that just mentioned, are natives of Europe, but their principal resort seems to be the intertropical countries of Africa.

ANTHOCHARIS DANÆ.
PLATE VII. Fig. 2.

Surface of the male pure white; the upper wings having a large triangular patch of bright carmine at the extremity bounded on the inner side by a black oblique band, and narrowly margined with the same colour externally, where the nervures are likewise black; there is likewise a black point at the extremity of the discoidal cell: under wings with a black border, variable in breadth, and occasionally macular. Under side impure white, with a black streak at the extremity of all the discoidal cells, those on the hinder wings divided by a reddish brown point; the apex of the upper wings fulvous-red, divided by a curved row of blackish spots, continued across the under wings as far as the anal angle. The female differs from the male in having a large space at the base of the wings dusky, and the marginal hand wider, and better defined on its inner edge.

Males sometimes occur in which the marginal band is entirely wanting in the hinder wings.

Found in the East Indies, at the Cape of Good Hope, &c.
