6S PLATE XCVII.

1 am not certain whether in the larva state it feeds on the Convo]«vulus, although I found it on a plant of that kind; as its climbingstalks and tendrils yvere so intricated with branches of white-thorn^Ostk, and broom, as to preclude any accurate determination*

I kept them in a gauze cage for the space of a fortnight, and sup-?plied them with fresti portions of the different plants every day, butcould never observe them take the least subsistence during the wholetime; they affixed their tails and hinder legs in the meshes of thegauze when I first removed them into the cage, and never shewedthe least signs of life after; as they held firmly by the gauze, in thepositions represented in our plate, I yvas very much disappointed to findon attempting to remove them, that two were dead; May 23d I obfervejthat which was alive threw out a very delicate white thread, as if aboutto spin a cone; the body gradually shrivelled at the upper part, whilethe lower became proportionably thicker; two days after it fell to thebottom of the cage and became a pupa, at first of a whitish, and afterof a fine green colour, marked at the narrow end with fliort blackstreaks. June 13th the Moth came forth.

At Fig . I. is shewn the head of the Caterpillar magnified ; it isgrey, with the jaws black, and is concealed beneath tvyo horns or pro-jections of the same green colour as the back.
