Show 279 teporata, Camnula atroxy and ( Edipoda venusta; of all of these I had in my own collection ordinary cabinet- specimens. It had been my intention to present at this time some general observations upon the geographical distribution of North American Orthoptera, and also a revision of the North American PezotetHgi and ( Edipodida, so richly represented in this collection. Other engagements prevent the present fulfillment of this intention, and I can only offer the student, in place of the latter, brief tables of the species obtained by the Survey daring this single season, which will be found preceding tne groans mentioned. A few specimens in an immature condition have not been determined. Respectfully submitted. SAMUEL H. SCUDDBR. Lieut. GEO. M. WHEELED, Corps of Engineers, in Charge, GRYLLIDES. 1.
