This seems to be a species of Northern Europe, or, at least, is only 

 recorded as such. It is abundant in the midland counties, ex. gr., at 

 Buddon Wood, and on the banks of the Soare, Leicestershire ; not 

 common near London ; a few only of var. h near Sandwich. The dis- 

 similar sexes were first paired by Fallen, who remarks (Hem. Suec, 

 pt. 2, p. 26), " Mirum sane quod in tanta individuorum copia ne 

 unicum quidem par copulatum vidisse contigerit." The insect must be 

 sought for close to the ground, at the roots of the herbage ; it will 

 hardly be obtained by sweeping.
