All enlarged. (After Osborn, Bur. Ent., Bull. 108.) universal in blue grass, it may also be found upon other species of grass and also in wheat and alfalfa. This sj)ecies is so abundant and wide-spread that it is almost impossible to sweep a patch of blue grass in any locality from INIaine to Washington, and south to northern Tennessee, without finding it in abundance. The nymphs pass through five distinct stages with differences in the shape of the head and development of wing pads and an increase in the number.
