 tions,) the removal of the fheep to a diftant pafture during the months 

 of June and July, whilft the greater number of the Bots are yet on

 fhewn in the annexed Plate, from which it will appear an infect of 

 fingular character, and no very irrconfiderable beauty. The fmaH 

 figure denotes the natural fize.
