The remarks made under the previous species apply with equal force 

 to the above records. 



Hadrotettix trifasciatus (Say). 



Raton, Colfax county, New Mexico. August 1, 1902. (Oslar.) 

 One male. 



Las Vegas, San Miguel county. New Mexico. July 23, 1 902. (Oslar.) 

 One female. 



Copper Basin, Arizona. (Oslar.) One immature male. 



Heliastus aridus (Bruner). 



Quartzsite, Yuma county, Arizona. April 20, 1903. Four females. 

 These specimens agree very well with a large New Mexican series. 



Paropomala virgata Scudder. 



Yuma county, Arizona. September, 1903. Three males, seven 

 females. Hebard Coll. 



The great amount of color variation noticed by Scudder is also 

 evident in this series, the range of general color being from chalky- 

 white and brownish to dull greenish. 



Schistoceroa shoshone (Thomas). 



Florence, Pinal county, Arizona. July 10, 25 and 26 and October 

 9, 1903. (C. R. Biederman.) Two males, four females. 



ScMstocerca vaga (Scudder). 



Florence, Pinal county, Arizona. May 8, 31 ; June 4, 8, 24; July 23, 

 26; August 25; September 20, 1903. (C. R. Biederman.) Six males, 

 seven females. 



Hesperotettix festivus Scudder. 



Florence, Pinal county, Arizona. August 10 and September 20, 

 1903. (C. R. Biederman.) Two males, three females. 



These individuals fully agree with a series from Phoenix, Arizona. 

 All five specimens possess reddish pregenicular annuli. 



Hesperotettix viridis (Thomas). 



Gallinas Canon, San Miguel county. New Mexico. July 21, 1902. 

 (Oslar.) One female. 



Jerome, Yavapai county, Arizona. June 27, 1902. (Oslar.) One 

 female. 



The collection also contains a short-winged individual, apparently 

 similar to the ones mentioned by Scudder, from Ruby Valley, Nevada, 

 which I have doubtfully referred here. It was taken at Prescott, 

 Arizona, July 5, 1902, by Oslar.
