eighth of an inch long, and broadly oval, are laid early in 

 June and hatch in from 11 to 13 da3's. The grubs hatch- 

 ing from these feed upon the plant-roots, growing but 

 slowly, as they require a bout two years to become full- 



grown. Meanwhile, however, each grub does its full share 

 of damage, especialh^ to corn and grass, and often to the 

 smaller grains. Its attacks have also long been feared by 

 the growers of straAvberries, potatoes, and garden truck.
