M. femoratus Burm. 



General Range. — Canadian Provinces to Virginia and Ken- 

 tucky, in the momitains to Georgia and Alabama, west to the Pacific 

 States, mostly northern in distribution. 



Local Distribution. — Very common in the Piedmont Plateau 

 and probably also in the Appalachian Region; common, but rather 

 more local in the Coastal Plain, least frequent in the Pine Barrens 

 and on the beaches, probably being a secondary introduction on the 

 latter. 



Ecological Distribution.^ — Adapted to a wide variety of con- 

 ditions, but seems to prefer more or less humid tracts with a con- 

 tinuous cover of succulent grasses and other vegetation; not in- 

 frequent, however, in quite dry situations where there is considerable 

 cover. It occurs in both campestral and sylvan stations.
