1 Tettix cucvillatus Scudder. 



2 Tettix graniilatus Kirby. 



3 Tettix ornatus Say. 



4 Tettigiclee lateralis Say. 



FAMILY 4. Locustidae or Long-liorned Grass- 

 hoppers. 



GROUP I. The Cricket-like Grasshoppers. 



1 Ceiithophilus iiiaculatus Harris. 



This is the only species known to exist about here. 



GROUP II. The Meadow Grasshoppers. 



1 • Conocephalus ensiger Harris. 



2 Xiphidivim brevipenne Scudder. 



3 Xiphidium fasciatuni De Geer. 



One cannot walk in our grassy fields late in summer without 

 being surrounded by myriads of these graceful little forms, and 

 the two species of Xiphidium seem equally abundant. Both the 

 green and the brown forms of C. ensiger occur. 



GROUP HI. The Katydids. 



1 Scudcleria ciirvicaiida De Geer. 



Specimens of Amblicoryphora rotundifolia Scudder, have been 

 received from near Boston, Mass., and in the Boston Museum of 

 Natural History is a specimen credited to the White Mountains, 

 marked "Bequest of C. A. Shurtleff." This species has not yet 

 been found about here, but we hope to determine whether it has a 

 continuo\is range between the two stations. 



FAMILY V. Grillidae or Crickets. 



1 Gryllotalpa borealis Burmeister.
