THOMAS ON ORTHOPTEEA OF DAKOTA AND MONTANA. 483 



Mountains in Wyoming, according to the specimens I have examined ; 

 but if I am correct in regard to a species Stal has described, it is found 

 as far west as Yancouver's Island. This writer has described as new, 

 under the name of Arphia sangiiinaria, a species from this island which 

 is undoubtedly Scudder's tenebrosa. 



Why this author has replaced Saussure's Tomonotus with Arphia, when 

 it includes the same species, it is difficult to say. 



3. Kippiscus xjliodnicoptera Germ. 



The number of specimens in this collection indicates that this is quite 

 common in the regions wheue the collections were made. 



While traveling through Southern Dakota in 1873, 1 noticed that, as I 

 advanced toward the northwest, (Edipoda (Hippiscus) rtcgosa approached 

 nearer and nearer in its characters to S. phcenicoptera, especially in the 

 color of the wings and the spots on the elytra. 



4. (Edipoda Idowa Thos. 



5. (Edipoda gracilis Thos. 



Specimens of both these little species are found in the collections j 

 this gives the northern limit of their range, so far as known. 



It is i)robable both species will have to be removed from (Edipoda as 

 that genus is now restricted, but at present I am unable to state whether 

 either will fall into any existing genus. The former will, in all proba- 

 bility, fall into the same limited group as (E. longipes Charp. 



6. (Edipoda neglecta Thos. 



Dr. Coues's discovery of this species along the northern boundary and 

 my discovery of it in Illinois show that it has a much wider range than 

 I at first supposed. 



7. Caloptenus spretus Thos. 



See note in regard to this destructive locust at the end of this paper. 

 It will be observed that I have placed my own name after this species, 

 indicating thereby, according to what I have previously stated, that I 

 claim to be the author. This I believe I have the right to do, as no 

 regular description is to be found anywhere previous to that I have 

 given, which distinguishes it from C. femur-ruhrum. Mr. Uhler did not 

 describe it, and does not claim to be the author. The name was first 

 given in my paper published in the Illinois State Agricultural Eeport. 



According to Stal's arrangement, there are no species of Calopteni in 

 the United States; this 2lm^ femur-ruhrum belonging to Pezottetix^^wh- 

 genus Melanoplms. 



There is no doubt that the Calopteni and Pezottetigi of IsTorth America 

 need revision, but I have strong doubts as to the correctness of Dr. 

 Stal's conclusions, which lead him to restore GalUptamus of Serville, cor- 

 rected into Calliptenus, drop Caloptenus of Burmeister entirely, and trans- 

 fer /ewmr-n(&rMm and other long- winged Calopteni to Fezottetix ; and I 

 have given my reasons for these doubts in another place.
