6S PLATE XCVIL 



I am not certain whether in the larva ftate it feeds on the Convol- 

 vulus, although I found it on a plant of that kind; as its climbing 

 ftalks and tendrils were fo intricated with branches of white-thorn, 

 oak, and broom, as to preclude any accurate determination. 



I kept them in a gauze cage for the fpace of a fortnight, and fup- 

 plied them with frefti portions of the different plants every day, but 

 could never obferve them take the leaft fubfiftence during the whole 

 time; they affixed their tails and hinder legs in the memes of the 

 gauze when I firft removed them into the cage, and never fhewed 

 the leaft figns of life after ; as they held firmly by the gauze, in the 

 pofitions reprefented in our plate, I was very much disappointed to find 

 on attempting to remove them, that two were dead ; May 23d I obferved 

 that which was alive threw out a very delicate white thread, as if about 

 to fpin a cone ; the body gradually fhrivelled at the upper part, while 

 the lower became proportionably thicker; two days after it fell to the 

 bottom of the cage and became a pupa, at firft of a whitifh, and after 

 of a fine green colour, marked at the narrow end with fliort black 

 ftreaks. June 13th the Moth came forth. 



At Fig. I. is fhewn the head of the Caterpillar magnified ; it is 

 grey, with the jaws black, and is concealed beneath two horns or pro- 

 jections of the fame green colour as the back.
