This handsome species measures upwards of three inches and a quarter between the tips of the wings; the latter are very much rounded, entire on the edges, and the hinder pair diverge widely from the abdomen; the superior fulvous from the base to the middle, with the costa, a slender streak at the base, and a central kidney-shaped spot, black; beyond this a pretty wide oblique band of sulphur yellow; the space between this band and the apex deep black, with eight unequal spots of dull yellow, slightly transparent, disposed in two irregular transverse bands, and two or three small white points at the apex. Inferior wings likewise with the inner half fulvous, the outer half black, emitting narrow stripes internally, one of which reaches nearly to the base, dividing the wing into two portions; towards the hinder margin are a few yellow spots: body cinereous, with a yellow longitudinal line on each side, and a similarly coloured band along the belly; antennæ reddish-brown, dusky at the base. A native of Surinam. [Illustration: PLATE 12. _Lizars sc._ _1. 2. Heliconia flora._ _3. ------ diaphana._ _4. Acræa Pasiphæ._ 1 & 2 from Surinam. 3 Jamaica. 4 Africa.] HELICONIA FLORA. PLATE XII. Figs. 1 and 2. _Godart._--Pap. Flora, _Cramer_, Pl. 257, fig. B, C The above plate affords examples of that division of the Heliconian butterflies, in which the greater proportion of the wings is denuded of scales and transparent. _H. Flora_ of Cramer very closely resembles _H. Ægle_ (Fabr.), and may possibly prove a mere variety of that species. It expands nearly two inches. The upper wings are black with two transparent bands, that next the base very large, lying parallel with the costa as far as the middle, and then descending obliquely towards the posterior angle, divided by a transverse black stripe, and a longitudinal nervure of the same colour; the second band macular, and placed near the apex. The under wings are transparent, the whole of the outer border surrounded by a black stripe, which is divided towards the angle by a fulvous line; the nervures black. Under side similar in design to the upper, but the whole of the outer border of the wings surrounded by a rust-coloured line, and the extreme edge marked with a few very small white points. Body cinereous above and greyish beneath; antennæ black. The caterpillar probably resembles that of _H. Ægle_, represented by Madam Merian, which is brown, clothed with hairs, and feeds on the _Sophora_. Both species are found in Surinam. HELICONIA DIAPHANA. PLATE XII. Fig. 3. _Godart._--Pap.
