THE WHITE-MARKED TUSSOCK-MOTH. 35 
GEOGRAPHICAL DISTRIBUTION. 
This species is widely distributed in North America east of the more 
timberless regions of the West, extending northward as far as Canada 
and southward well into the Southern States. It is most abundant in 
the Middle and New England States, but it is a noticeable fact that 
wherever it occurs it is more frequent within our cities, or in gardens 
and orchards near by, than in the woods remote from human habitation.
