1334 IIIE ISUTTEIIFLIES OF NEW ENGLAND. 



chusetts ; Hylephila pliylaeus, also distinctively southern and tropical in 

 its distribution, whicli has sometimes appeared in considerable numbers on 

 the southern coast ; and finally Erynnis attains, a southern butterfly which 

 once in a while is taken in large numbers in Connecticut and even about 

 Boston. 



There are a number of" other cases where southern butterflies have in 

 one or two cases been taken singly in New England or its confines, wan- 

 dering raiders from the southern armies, but those which have been 

 related give a clew to the mode in which New England was originally 

 colonized, and indicate that whether or not tiie process is still going on, 

 there is at least a constant fluctuation in tiie components of its butterfly 

 fauna, or in the relative abundance of those types whicii maintain a pre- 

 carious foothold from year to 3'ear.
