The locust, or " grasshopper," as it is called in this 

 country, is a good type of the class of Insects, and its 

 wide range throughout the United States will enable 

 teachers in any part of the country to obtain speci- 

 mens without difficulty. In New England there are 

 many species ; but one of the commonest and largest 

 kinds is the yellow-striped locust, Caloptenus fejnora- 

 tus, Burm. (PL I., Figs, i, 2, 3, p. 10.) The lubber 

 locust, Dictyophorus I'eticulatus^ common at the South, 

 *shows the parts more plainly, owing to its large size. 

 Specimens can be obtained from Florida; but when 

 this is inconvenient, our native locusts can be used. 



Confusion has arisen in regard to the names " locust " 

 and "grasshopper." The former has been incorrectly 

 applied by some authors to the cicada, or harvest-fly 

 (Fig. 78), a form well known by its shrill, trilhng note. 

 The cicada, however, does not even belong to the 

 same order as the true locust, it being one of the 

 Hemiptera, or Bugs (see p. 131). 



The name " grasshopper " has also been applied by 

 Americans to certain species of true locusts which are 

 known by their appropriate name in Europe and other 



^ For figures of this locust (also named Romalea )nicroptera)
