Trenton Falls, Massachusetts, California'? B.M. 



I cannot see sufficient reason, in Mr. Packard's cumparative 

 description, for separating P. californica as a species ; it is well 

 known that the Ardiidm are more su.bject to variation than 

 most groups of Lepidoptera, and may be lighter or darker in 

 colour, or differ slightly in contour, from the same batch of eggs : 

 we have two or three examples labelled with a dark green ticket, 

 (which generally indicates species received by us from California, 

 if not from Europe), one of these is darker and more heavily 

 marked than usual, but I should not hesitate for a moment to 

 place it with P. Isabella.
