[A small grayish-brown bug. feeding on the foliage of the 

 grapevine, etc.] 



In 1882 specimens of the larva and i)upa ( F'ig. 1836) of this 

 species were sent me, accompanied by a note stating that these 

 insects Avere destroying the foliage of grapevines (Fig. 183a), 

 and in two or three weeks later specimens of the perfect insect 

 were received. The first letter received with these specimens 

 stated that vines on about five rods stjuare of ground were 

 attacked ; ten days later nearly two acres were infested before 

 the insects were checked from spreading.
