_Upper Side._ Antennæ white on one side, and brown on the other. Head and thorax brown grey; the latter at the base being ash-coloured, having a black line running on each side. Abdomen brown grey, encircled with rings of a dirty black, divided on the top by a broad line of brown grey, through which runs a black line from the base to the extremity. Anterior wings brown grey, with three short black lines in the middle of each wing; at the tips rises another irregular narrow black line, running towards the middle of the wing, and chequered with white and black. Posterior wings brown grey, immaculate, being a little paler towards the shoulders; the wings are entire. Cilia alternately black and white. _Under Side._ The breast and abdomen are ash-coloured. All the wings brown grey, immaculate. Cilia spotted as above. This insect is attached to the pine, and is consequently found in the great forests in Germany, and other parts of Continental Europe. This accounts for its scarcity in England, and for its having been occasionally found in the pine forests of Scotland by Dr. Leach and Mr. Wilson. The larva is described by Mr. Stephens as being entirely yellow in its first skin, in the second green with yellow stripes, in the third deeper green, with three longitudinal lemon-yellow lines on each side, and finally of a rich green with a {54}brown dorsal line; the sides with two deep yellow ones; the anterior and first segment of the body yellow, the latter spotted with black; the horn, which was previously straight, becomes curved and black. It feeds on various species of pine, as Pinus abies, sylvestris, Strobus, &c. The chrysalis is dark brown, changing to maroon; the tongue-sheath is short. SPHINX ELLO. Plate XXVII. fig. 3.
