The four wings are covered with very small scales, easily detached, and resembling a fine powder: at the base of each of the upper wings is an appendage, prolonged backwards, which is termed tegula, or pterygoda; the presence of this appendage forms one of the distinctive characters of the 166 ENTOMOLOGY. order. The wings appear membranaceous and simply veined, when the dust, by which they are covered, is removed. In many species, a portion, more or less large, of the wings is naked and transpa...rent; the scales are fixed by means of a pedicle, with great symmetry, like the tiles of a roof: their forms are various, very often triangular, with the upper lobe broad and dentated ; the colours are equally diversified, and often extremely brilliant. The head is furnished, in addition to the two ordinary eyes, with two ocelli, placed on each side, near the internal margin of the others. The thorax is formed of three segments, intimately united, the second, or meso-thorax, being the largest. The scutellum is tri- angular: the antennae are composed of numerous joints; in the Diurnae or (Butterflies which fly by day, ) they are always simple, and thickest at the extremity; and in the nocturnal species, the antennae are filiform, simple, serrated, or pectinated.
