NOTES ON ORTHOPTERA FROlfl OKLAHOMA ANO 



INDIAN TERRITORY, WITH DESCRIPTIONS 



OF THREE NEW SPECIES. 



BY A. N. CAUDELL, WASHINGTON, D. C. 



During the past summer my wife made a small collection of the 

 Orthoptera in Oklahoma, and also collected a few specimens in the 

 Indian Territory. The material numbers in all nearly 200 speci- 

 mens constituting 33 species, three of which are apparently uude- 

 scribed. The following notes are based upon this collection and a 

 few specimens collected by myself in the two Territories at various 

 times during the past nine years. Many of the species are men- 

 tioned merely as a matter of record : 



(1.) — Dabia minor Linn. 



Forficula minor Linn., Syst. Nat. ed., x, i, 423 (1758). 



One male ; Stillwater, Payne Co., Oklahoma, April 23, 1893. 



(2.) — Ischnoptera pennsylvanica De Geer. 



Blatta pen-nsylvuniat De Geer, Mem., iii, 537, pi. 44, fig. 4 (1773). 



One inunature specimen under bark in the Creek Nation, Indian 

 Territory, May 31, 1901 ; and two mature individuals from Still- 

 water, Oklahoma, in 1893. This species has not, I believe, been 

 recorded so far south, and the specimens in my possession may be- 

 long to an allied species, though they seem to agree perfectly with 

 typical northern species. 



(3.) — Stylopyg-a orientalis Linn. 



Blalta orientalis Linn., Syst. Nat. ed., x, i, 424 (1758). 



Stillwater, Oklahoma, 1892. 



(4.)— Blatta g-ermanica Linn. 



Blatta germaiiica Linn., Syst., Nat. ed., xii, ii, 688 (1767V 



Stillwater, Okla., 1893. 



(5.) — Stagmomantis Carolina Linn. 



Gryllus (Mantis) Carolina Linn., Cent. Ins. Ear., 13 (1763). 



Two males, one female; Perkins, Payne Co., Okla., Oct. 7, 1901. 



'6.) — Diapheromera velieii Walsh. 



Diapheromera velieii Walsh, Proc. Ent. Soc, Philada., iii, 410 (1864).
