They are heavy Insects, and the inferior wings project beyond the superior, as in several of the genus Bombyx( 1 ). Our third division, that of the SEslADEs, comprises those in which the antenne£ are always simple, fusiform and elongated, and frequently terminated as in the preceding subgenera, by a little bundle of set<£ or scales; in which the inferior pa1pi, slender and narrow, have three very distinct joints, the last tapering to a point; and where the extremity of the posterior tibie£ is armed with ve1·y stout spines. The abdomen in most of them is ter·minated by a sort of brush. The caterpi1lars feed on the internal part of the stems or roots of plants, like those of the Hepiali and Cossi, are naked, without a posterior horn, and construct their cocoons in these stems with the debris of the substance on which they have fed. SEsiA. Where the antenne£ are terminated by a little tuft of scales. The wings are horizontal and marked with tranaparent spots. The sc~les of the posterior extremity of the abdomen form a brush. Several of these Insects bear a close resemblance to :'\'Vasps or other Hymenoptera, to Diptera, &c.(~) THYRis, HofF. Illig. The Thyrides resemble the Sesi<£, but their antenne£ are much more slender, almost setaceous, and destitute of the terminal tuft. Their wings are angular and dentated. Their abdomen terminates in a point. M. Bois-Duval, whose knowledge of Lepidoptera in general, and of those in Europe particularly, is not inferior to that of our· most celebrated entomologists, and who is about to publish a Monograph of the Zyg<£nides that has received the approbation of the Royal Academy of Sciences, has observed the metamorphosis of the most known species( 3.).
