on a leaf, all the four wings are expanded horizontally; and rarely, if ever, take a vertical position, like those of the species of the Linnæan genus _Papilio_, when at rest[38].” URANIA SLOANUS. PLATE XXIX. Fig. 1. _Godart._--Pap. Sloanus, _Cramer_, Pl. 85, fig. E, F.--Pap. Leilius, _Var. Fabr._--Leilius Occidentalis, _Swainson, Illus._ Pl. 129. Expands about two inches and a half or three inches; surface deep black; the upper wings each with six or seven transverse lines of golden green, and near the middle a band of that colour bifid (sometimes trifid) anteriorly. Under wings with a central band of bright coppery red, irregularly indented, the abdominal margin more or less gilded green; the tail black with a few emerald green spots. Design on the under side corresponding to that on the surface, the green paler. Body black above, with a dorsal line of golden green, and another on each side; brownish beneath. This handsome species bears the name of the celebrated Sir Hans Sloane, the early historian of Jamaica, who figured it in his work (Pl. 239, fig. 11, 12). It is accounted a rare insect, and, we believe, has hitherto been found only in the West Indian Islands. [Illustration: PLATE 29. _1. Urania Sloanus._ _2. Urania Leilus._ W. Indies.

Gloss._--Leilus Surinamensis, _Swainson. Zool. Illus._ Pl. 125.--Le Page de Cayenne, _Daubenton_, Pl. enlum. 71, fig. 1. Larger than the preceding, frequently expanding four inches. Ground colour deep velvet black on both sides, the pictorial design on the upper wings nearly as in _U. Sloanus_, there being eight or nine slender transverse lines, slightly curved, of beautiful green, with a silky lustre, and the usual band near the middle sometimes divided into three or four ramifications as it approaches the costa. A band of light sericeous green likewise runs across the inferior wings, deeply indented on both sides, and often quite interrupted by transverse patches of the ground colour; the tail nearly white; the fringe pure white. Body thick and robust, especially in the females; black, rayed with emerald green. This lovely insect appears to be pretty abundant in Surinam, as great numbers have been transmitted to this country.
