There are many peculiar characters presented in this species independent of its colour: the spiral whorls are strongly plaited longitudinally about half their length, and marked very slightly (but sufficiently distinct) with several oblique indented striae; the principal whorl has a row of indented and unequal sulcations near the suture, and a slight appearance of elevation along the white transverse band; the outer lip is thick, broad, and flattened beneath; but the margin is reflected back, and forms a prominent rim on the upper surface. The shell, when viewed closely, appears rough with minute scale-like elevations, very much resembling shagreen. * * * * * Pl. 5 [Illustration] COLIAS Statira. * * * * * GENERIC CHARACTER. _Palpi breves, curvati, compressi ad linguam, squamis dense tecti. Articulis tribus; primo longissimo, ad basin curvato, ultra erecto; secundo erecto, brevi; tertio minimo, proclivi; apice nudo, obtuso. Antennae breves, cylindraceae, ad apicem nudum et abrupte truncatum sensim incrassatae. Alae anteriores trigonae. Abdomen maris, ultimo articulo acuto, et subtus tenui unco incurvato; valvis magnis, attenuatis, aduncis._ Typus Genericus _Colias Ebule._ Palpi short, curved, compressed on the tongue, thickly covered with scales. Articulations three; the first very long, curved at the base, erect beyond; the second erect, short; the third minute, inclining forward; the tip naked, obtuse. Antennae short, cylindric, gradually thickening to their tip, which is naked and abruptly truncate. Anterior wings trigonal. Abdomen of the male with the last joint pointed, and a slender incurved hook beneath; the valves large, attenuated and hooked. Generic Type _Colias Ebule_. * * * * * SPECIFIC CHARACTER. _C. alis dilute flavis, vel fulvis; anticis supra, puncto medio margineque extimo, nigris; subtus ferrugineis; posticis subtus, singulis duobus niveis punctis inaequalibus; palpis productis._ Wings diluted yellow or fulvous; anterior with a black border and central dot, which beneath is ferrugineous; posterior beneath, each with two unequal snowy spots; palpi lengthened.--_Female._ Papilio Statira. _Cramer, pl._ cxx. _fig._ C. D. * * * * * The present insect is selected to illustrate a very elegant family of Butterflies, whose predominant tints are composed of orange, yellow, and white, variously blended and disposed in a greater or less degree throughout all the species. The generic characters above given will distinguish them as peculiar to the tropics, and principally those of South America; one or two species only being found in Africa, and five or six inhabiting India.
