heavier, more bluntly toothed and better adapted 

 for eating coarse vegetable foods. 



3. A large prothorax shieldshaped above, that more or 

 less overlaps the head in front, and the synthorax 

 behind. 



4. The males are equipped with a sort of musical or 

 chirping apparatus. 



5. The end of the abdomen in the female is armed 

 with an ovipositor for making the holes in which 

 the eggs are laid. 



6. The nymphs as already noted (page 15), have the 

 wing pads inverted in position on the back.

Let us begin our study of the group with one of the short- 

 horned grasshoppers. There are many kinds of these and 

 several kinds may be found in any corn field or meadow 

 where they eat notches in the edges of the leaves of the corn 

 and the grasses. One familiar gray species rises from the 

 dusty roadside on our approach, and flies away on rustling 

 wings, which show a conspicuous yellow border behind.
