XVr. OTHER MEMBERS OF THE CLASS - 

 INSECTA 



Arthropoda (continued) 



The class, Insecla, is divided into nineteen subdivisions 

 or orders. It is impossible, in this book, to discuss all of 

 these orders, nor would it be wise, because the members of 

 some of the orders would be quite strange and unfamiliar 

 to us. Therefore, we shall confine our attention to seven 

 orders that contain the more common and widely known 

 insects. 



Grasshoppers, crickets, cockroaches, etc. — These are 

 all closely related insects and belong in the order known 

 as Orthoplera (straight wing). The word refers to the 

 straight, fanlike plaits into which the hind wings are 

 folded when they are at rest. 



Tfie insects in this order have four wings, the front pair 

 being thick and not folded, while the hind wings are thin and 

 folded in straight, fanlike- plaits when at rest. They have 

 biting mouth parts and the mMamorpliosis is incomplete. 



There are many species of grasshoppers and they are 

 widely distributed over the earth. There are two families 

 of grasshoppers: the short-horned, those having short 

 antennse, and the long-horned, those with long, slender 

 antennae. The short-horned grasshoppers are the true 

 locusts, some species of which are referred to in the Bible. 

 They often sweep over a country and destroy all the herbage. 

 The little red-legged locust is very common in the northern
