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

 description, for separating P. califoruica as a S})ecies ; it is well 

 known that the Arctiidai are more subject 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 lieavily 

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

 place it with P. l.saheMa.
