SEPTEMBER 41 



The " tobacco " is parth- digested food and seems to be 

 used for defensive purposes. 



Back of the head is the chest, to each of whose three 

 parts is attached a pair of legs. The first pair points 

 forward, the second outward and backward, and the 

 third, which is more than double the length of either of 

 the others, points upward and backward. In leaping, 

 the insect uses its first pair of legs as points of resistance, 

 pushing with the third pair, Avhich then straighten out 

 as he jumps long distances into the air. In walking, the 

 legs seem to be used somewhat alternately. 



The first pair of wings, wing covers, serve to protect 

 the delicate gauzy wings folded like a fan beneath. Both 

 are strengthened by veins. 



The male locust sings by rubbing his legs against the 

 wing covers. 



The abdomen is made up of ten segments, which gives 

 much freedom of motion. The nu- 

 merous breathing holes are along ; cercus 

 each side, so that a locust would 

 have to be held, not with the head, 

 but with the body in the Avater in 



order to drown it. Abdomen, Male Locust. 



At the end of the abdomen of the 

 female are hard brown pincer-like organs, which make the 

 hole in the ground in which the eggs are laid. These eggs, 

 usually about twenty-eight in number, are long, yellow in 

 color, and very commonly found. The young locusts hatch 

 out in the early summer, looking very like the mother, 

 except that they have no wings. About July they shed 

 the outer covering and come out larger and with wing 

 pads developed. In succeeding moults, these increase in 

 size, until, at last, in the fourth moult, the wings develop.
