Insects Injurions to the Cereal Grains, and the 

 Grass Crops, including Clover, 



In classifying insects according to the plants they in- 

 jure, there is often an over-lapping. Thus the White 

 Grub, while mentioned elsewhere, is often one of the 

 worst enemies to the grower of grass, whether in the 

 meadow or pasture ; it also attacks the grains, as do 

 several of the Cut-worms. When there is, as in some 

 western localities, an invasion of the Rocky Mountain 

 Grasshopper, scarcely any green thing escapes its attacks. 

 We give in this division, an account of the most com- 

 mon enemies to the grain grower, and those which at- 

 tack grass lands. 



THE CHINCH-BUG. 



(Blissus leucopterus, Say.) 



NATURAL HISTORY OF THE CHIKCH-BUG. 



The food of the Chinch-bug consists of the grasses and 

 cereals, wild and cultivated, and accounts of its injur- 

 ing other plants are misleading, allied species being con- 

 founded with it. Belonging to the Half -wing Bugs 

 (Heteroptera), its food is obtained by suction, so that the 

 plants attacked are sapped of their life, and not eaten up. 

 The mature Chinch-bug (fig. 79) is less then a fourth of 

 an inch long; its appearance at different stages is shown 

 in fig. 78, the hair lines indicating the natural sizes. The 

 eggs (fig. 78, a, #,) are amber-colored, the young bugs
