I follow Dr. Hagen in uniting these three forms ; spe- 

 cimens of each of them in my collection fally bear out 

 his opinion, and the figures in Edwards' plates show how 

 variable Philodice is. As I have before mentioned, the 

 name Anthyale, Hiib., which in Staudinger's Catalogue 

 is used for Pelidne, Bdv., must without doubt be con- 

 sidered a synonym of Philodice.

 I follow Dr. Hagen entirely in his views as to the 

 synonymy of this species, and, as he has had access to 

 most of the types, and has gone into the subject very 

 carefully in a way which no European lepidopterist is in 

 a position to do, am much indebted to him for in- 

 terpreting the nomenclature of such a difficult species, 

 some of the forms of which I was obliged to pass by 

 with doubt in my first paper. 



The next question, however, to be considered is 

 whether, having gone so far, we must not go a step
