VADE MECUM. 131 



with the English ones, which donbt is increaspd by Mr. 

 Stephens' description and figure, which does not altogether 

 agree with Mr. Haworth'a description ; who says of the 

 primary wings, that underneatii they are wliitisli. From the 

 rose-coloured edge or fringe of tlie wings in C. Palceno, as 

 described by Ochsenheimer, which Mr. Stephens lias also 

 observed in C. Europo?ne, there seems some rea.son for think- 

 ing them synonymous ; but as the female difl'ers very mate- 

 rially (see the descriptions), Mr. Stephens appears Justified 

 in considering them as distinct. 

 N. B. — The note in p. 36, was inserted by some mistake.
