hopper : the second, the Gryttina, appear to frequent trees and shrubs 

 more than the other tribes, the members of which generally keep 

 among herbage ; and, in accordance with this habit, many of the

 In the small circle the object is represented of the natural size. 



exotic species have wing-cases, which present the most perfect resem- 

 blance to leaves both in colour and veining. There are several British 

 species, one of which (the Gryttus viridissi<mus, Grasshopper,) is very 

 common in marshy situations. 



Of the tribe Achetina, the common Cricket (Acheta domestica), 

 fig. 154, the noisy little denizen of our kitchen-hearths, serves as an ex- 

 ample. These insects have the antennae slender and tapering, and often 

 considerably longer than the body. They agree with the Gryllina in 

 the structure of the singing apparatus \ but the wings, instead of being 

 arranged in the form of a high pitched roof, are laid flat upon the back. 

 Some of them possess ocelli, whilst others are destitute of those organs. 

 The hinder wings are very long, and folded up in such a manner that 

 they project beyond the wing-cases in the form of a pair of tapering 

 tails; the abdomen is also furnished, in both sexes, with a pair of 

 pilose, bristle-shaped, caudal appendages, and in the female with a 

 long, slender ovipositor, composed of'two filaments, laid side by side, 

 and somewhat thickened at the tip. The tarsi are three-jointed.
