 Jersey (Smith), the borders of Lake Michigan, in Indiana (Blatchley), 

 and Nebraska (Bruner), the last, I think, by mistake. 



This si)ecies is very closely allied to M. hn-idus^ but differs in its lack 

 of any projecting part to the furcula. the less divergent forks of the 

 cerci, less elevated, apical margin of the subgenital i)Iate and greater 

 niaculation of the tegmina. 



I first observed this species in Sudbury, Vermont, in August, 1808, 

 abundant in the vicinity of groves in dry .ipland pastures; compara- 

 tively few M. femur ruhrum occurred with them, the latter being found 

 in open sunny si)ots, and especially in hollows in the lowlands. 

 McNeill, who was the first to find it in the West, says that in Illinois 

 ^'it is restricted to the tops of hills and the sides of ravines which are 

 too barren for pasturage.'" At Provincetown, Massachusetts, I found 

 it at the sandy edges of neglected cranberry beds. According to 

 Blatchley, this species maybe found in i>airing time ''among the leaves 

 and branches of the iron-weed." I found one specimen devouring a per-
