Lake and Marion counties, Ind., scarce, May 29 — June 8. 

 Wolf Lake, 111., July 19. Taken by sweeping grasses and sedges 

 along the margins of ponds and lakes. Ranges from Massa- 

 chusetts and Connecticut west to Dakota and southwest to

 winter beneath stones in sheltered places and may be swept 

 from plants in damp situations in June and July." In New 

 Jersey Smith found it common on cranberry bogs in June.
