A letter was read from Prof. M. McDonald, of the Virginia 

 Military Institute, at Lexington, Va., reporting the occurrence 

 there of living HeUcina occulta, Say, in immense quantities. 

 The species was supposed to be extinct until discovered two or 

 three years since by Prof. McDonald. It has also occurred, 

 rarely, at Milwaukie, Wisconsin. Individuals were found by 

 Prof. McD. upon the stems and leaves of plants in some cases 

 at an elevation of two to three feet above the surface of the 

 ground.
