Emerton — Four Burrowing Lycosa 



33 



This species is common in eastern Massachusetts in sandy soil 

 at least partly covered with sod. At Plymouth it lives in the 

 sandy hills within quarter of a mile of the seashore where pikei 

 lives in the sand fields. At Tyngsboro it lives in similar places 

 along the Merrimack River and in Wellesley and Waltham in 

 open pastures with gravelly soil and thick sod. At the railroad 

 station Karner, west of Albany, N. Y., it is abundant in the bar- 

 ren sandy fields. Southward it is common around Washington 

 and at Atlanta, Ga.
