THE GROUND BEETLES.

0. nmander Fisch. is a, boreal species which has been taken by 

 Woleott near Chicago and doubtless occurs in the northern third of 

 Indiana. He finds it in spring, early summer and autumn, by 

 tearing the sod away from the large exposed roots of oak and other 

 trees in sparsely wooded pasture land, the beetle occurring between 

 the sod and the roots.
