The distribution of this species is still very imperfectly known. 

 It appears to be rather generally distributed, at least near the 

 coast, from New Haven to Boston. The only inland records 

 are Farmington, Me., Center Harbor, N. H., and Sudbury, 

 Mass. North of Boston it seems to be definitely synanthropic. 



Philoscia Latreilie. 



Subgenus Philoscia Verhoeff. 



Philoscia (Philoscia) muscorum (Scopoli), var. sylvestris (Fabricius). 



I have followed the view of Dahl and Herold as to the name of 

 this variety.

Herold (1929, p. 616) has pointed out that this form is definite- 

 ly associated with soils of a marked salinity. This is apparently 

 true in New England. The only exception known to me is 

 Sharon, Mass.
