ORDER Hi, 



STRAIGHT- WINGED INSECTS (ORTHOPTERA). 



ALL insects which have transversely movable jaws, mem 

 braneous wings (a few have no wings), six legs, and undergo 

 no metamorphosis, belong to the Order Orthoptera, which 

 signifies in English &quot; Straight-winged.&quot; Among these are 

 Grasshoppers, Walking-leaves, Crickets, Cockroaches, Ear 

 wigs, Soothsayers, Walking-sticks, etc. 



Grasshoppers. 



Grasshoppers have been divided by Linnaeus into two 

 families ; viz., Grillidcc and Locustidce. 



The GEILLIDJE, or those properly called Grasshoppers, 

 dwell, as their name indicates, upon the ground, in mead 

 ows and fields. They have short thread-like feelers, and 

 their females are destitute of an ovipositor ; but both sexes, 

 when flying, produce a stridulating sound by rubbing their 

 saw-like hind legs upon their parchment-like wings. 



The LOCUSTID.E have very long filiform antennae. The 

 females are provided with a long sword-like ovipositor, and 

 the males are furnished with a spot resembling an eye of 

 glass at the base of each wing-cover, which they rub to 

 gether, and thus produce their peculiar sound. Their wing- 

 covers, when at rest, are disposed like a slanting roof. 

 Their color is generally bright green, which, after death, 

 soon changes into a dingy yellow, but may be preserved by 

 taking out the intestines of the animal and filling the ab 

 dominal cavity with cotton.
