At first, the leaf enveloping the cocoon remainsgreen, but soon changes to a red or brown, when it becomesbrittle, and is gradually carried away by the winds and stormsof winter, until, finally, nothing remains except the cocoonitself, which is firmly suspended by the silk which oncecovered the footstalk of the leaf. The instinct of the cater-pillar in thus providing for the permanent attachment of itsfuture habitation, appears far to exceed that shown by anyother caterpillars, if we except those of the pomegranate but-terfly of the East Indies, of which I have pubhshed a memoirin the Transactions of the Entomological Society of silk spun by the Prometheus moth, according to , is as fine, and is produced in as great abundance, as that LEPIDOPTERA : TRANSFORMATIONS. 403 furnished by the Bomhyx mori, or common silk-worm ; butit is of a darker colour, and will, it is feared, always present.

I cannot conclude these observa-tions without congratulating my readers upon that widely-extending spirit of observation into the wonders of the crea-tion, of which Mr. Peales work exhibits an example,trusting, at the same time, that this beautiful book will meetwith that success which it so richly deserves. Other interesting instances of the care with which theconstruction of these cocoons is undertaken, have alreadybeen given in preceding pages; and the general structure ofLepidopterous chrysalides is detailed in p. 207, &c. In the earlier editions of the Systema NaturcB, Linnaeusadopted only two genera: namely, Papilio for the butter-flies, and Phalcena for the moths. Tn t
