for its size and elegance. The upper wings are of a fine dark grey, variegated with orange and white.; the under are of a bright orange, marked by a pair of black bands. The body is orange colour, barred with black; but its greatest singularity is a very large patch on the top of the thorax, representing the figure of a death's head. Corresponding with this melancholy insignia, this insect emits a shrill sound, very much like that of a bat or mouse; and, from the union of these circumstances, is regarded by the vulgar, in many parts of Europe, as an omen of death. The caterpillar to which the Atropos owes its origin, is supe nor in size and beauty to most others. It is sometimes nearly five inches long, is of a bright yellow, the sides marked by a row of elegant broad stripes, of a mixed violet and sky-blue colour. The tops of these bands form angles on the back, and are varied with jet black specks. If you wish to see this handsome caterpillar, you must search in the potatoe plants or jessa:rnine trees, which are its favourite food.
