I regard this description as undoubtedly referable to the 

 fem?.le of our Clouded Yellow^ in which the spotting of the 

 border is often divided into two patches, and which is m.uch 

 yellower than either E. palccno or the Pale Clouded Yellow. 

 All the figures originally quoted by Linn^us (Petiver's and 

 Roesel's) represent the female of the Clouded Yellow, to which 

 I have ventured to restore the original name of hyale ; and it 

 was recognised as that species by most of Linn^us' contem- 

 poraries, though Geoffroy and Scopoli confounded the Pale 

 Clouded Yellow with it as a variety, or as the female, while 

 others mistook it for E. palcj^no (Linn.).
