[Read May 21st, 1862.] 

 The North American Orthoptera have been very much 

 neglected, very little special attention having been paid 

 to them ; for besides the earlier general works of Lin- 

 neus, Fabricius, De Geer, Stoll, and Palisot de Beauvais, 

 and the more recent ones of Burmeister and Serville, 

 which included descriptions of North American Orthop- 

 tera among others, the only other notices of our species 

 have been in the few scattered descriptions by Say, Hal- 

 deman, Kirby, Girard, and myself, if we except only these 

 two: — Harris's mention of the New England Orthoptera 

 in his " Report on Lisects of New England Injurious to 



JOURNAL B. S. N. II. 52 NOVEMBEK, 1862.
