We do not find that this rare and beautiful Infedl has been de- 

 fcribed either by Linnaiu or Fabrtdus. It was taken a few years 

 llnce in Epping Forefl: by Mr. Bentley, an eminent Colle£tor of 

 Englifli Infefls, and noticed by Thomas Marfham, Efq. Sec. L. S. 

 in his Manufcript Notes, under the fpecific name Semi-argentata.

 cept them, we have not heard of any being met with for fome time.
