inhabits uplands rather than moist grounds. When about to stridulate, 

 these insects place themselves in a nearly horizontal position, with the 

 head a little elevated ; they then raise both hind legs at once, and grate 

 the thighs against the outer surface of the elytra. The first one or two 

 movements are frequently noiseless or faint. In sunny weather the notes

are produced at the rate of about si.x a second, and are continued from 

 one and a half to two and a half seconds. When the sky is overcast, the 

 movements are less rapid. 



17. Stenobothrus maadipennis Scudd. The range of this insect is 

 similar to that of the preceding. It is found in the White Mountain 

 valleys and all over the state. Also, westward as far as Minnesota, 

 Wyoming, and Nebraska. 



1 8. Stenobothrus cequalis Scudd. This insect is believed by Smith to 

 be identical with the preceding, and may prove to be. It also occurs in 

 the White Mountain valleys and in other parts of New Hampshire, and 

 has been taken in Maine, Massachusetts, New York, the middle states, 

 and Minnesota. 



19. Tragocephala infitscata Harr. A wide -spread insect, not only 

 found in every part of the state, including the valleys of the White 

 Mountain region, and up at least to the sub-alpine zone, but reaching 

 southward to North Carolina and Louisiana, and westward to Nebraska 

 and Colorado. 



20. Tragocephala sordida Stal. This grasshopper is found in the 

 southern half of the state, and extends from Maine, in the latitude of 

 the White Mountains, to Maryland and Tennessee in the south, and 

 Nebraska, Iowa, and Minnesota in the west. It has also been taken at 

 London, Ontario, Canada. 



21. Arcyptcra liueata Scudd. This grasshopper has not been taken in 

 the state, but, having been found at Nor\vay, Me., Williamstown and 

 Andover, Mass., it doubtless occurs here. It has also been taken in the 

 valley of the Red river of the north. 



22. Arcyptcra gracilis Scudd. • This insect is abundant at Jefferson
