Most of the other species of Farnassius closely resemble tliis; but F. mnemosytie, also an Alpine species, has no red spots, but only two black spots on the fore wings, and even these disappear in the Siberian F. stubbemlorfii. The few known caterpillars of this genus are blacky with rows of red spots on the .sides, and feed on different species of saxifrage. The genus Teiiwjui/jius is distinguished from any othii- of the sub-family by the unusual length of its ji,il|>i. T. imperiiilis is one of the rarest and most itifiil of Himalayan Butterflies, and measures about five inches across the wings, which are black, dusted all o\ei with -iihet^ gieen, and banded with purple. The hind wings are very strongly dpiitated, with one long tad ui the male, and three in the female. The great genus Fapilio, which includes the well-known Swallow-tail Butterflies, may be known from the other genera of the family by its longer antenna; and very short palj)i. There are about 500 species known at present, but only four are European, and the genus attains its maximum of size, beauty, and variety in Africa and the Eastern Arcliipelago. It is in the latter region that the splendid Bird-winged Butterflies, belonging to the .subgenus Ornlihoptera, may be found. All the species included in it are very large insects, with long fore wings, measuring from five to eight or nine inches across, and short, more or less dcntated hind wings, which, however, are not tailad. The first gi-oup have velvety-blaok wings, with a broad green sti-ipe running parallel to the costa, and a narrower bar running near the inner margin and curving up a
