Pink Grasshoppers. 



By Samuel H. Scudder, Cambridge, Mass. 

 See plate VI. 



The insects commonly called grasshoppers by English speak- 

 ing peoples are separated by naturalists into two great families, 

 in one of which the antennae are much shorter than the body 

 and moderately thick, while in the other they are longer, often" 

 very much longer, than the body, and are exceedingly slender, 

 tapering and thread like. 



The former are generally found on the ground and as a 

 rule are of some brown color, while the latter, at least when 

 winged, are commonly confined to trees and bushes and are 

 usually green. There are, however, many exceptions both as 

 to habitat and color. The long-horned or green grasshoppers 

 are usually green throughout, or with the exception of some 

 minute and inconspicuous spots or streaks ; but many species 

 exist in two forms, one of which is grass-green, while the other 

 is dead-leaf -brown, there being no difference between them, ex- 

 cept in the general tint. 



It is to this group of grasshoppers that belong all the noisy 

 tribes of Orthoptera (excepting only the crickets), of which the
