CORRESPONDENCE. 



pieris vernalis and p. protodice. 

 Dear Sir, — 



In confirmation of Mr. Bean's conclusions, as given in the November 

 number, I would state that I have long known vemalis to be but the 

 spring form of protodice, and believe I so wrote to Mr. Edwards some time 

 ago. What is probably the first record of this opinion will be found in 

 my 9th Report on the Insects of Missouri (p. 57). My experience accords 

 with Mr. Bean's as to there being every possible gradation between the 

 extreme vemalis form and the typical protodice. What is true of these 

 two supposed species will, I am confident, be found to be equally true 

 of several other of Mr. Edwards' described species, especially in Colias ,-, 

 but no one perhaps is more willing to admit the fact at present than Mr 

 Edwards himself, or is doing more by careful breeding to decrease the 



number of his own species.
