HICKORY. LEAVES. 



rings upon the antennae, which are always broad in our insect and 

 are one of the first marks which the eye notices, but are repre- 

 sented as quite narrow and inconspicuous in the European. This 

 is common upon hickory leaves; but the insects of this genus do 

 not crowd themselves together and remain stationary like other 

 plant lice.

 draw their nourishment from grass and growing cro])S of grain this 

 very common si)ecies is usually found upon the leaves of a variety of

 other kind, according to my observations.
