Schiatocerca venusta Scudder. 



Bill Williams Fork, Mohave- Yuma counties, Ariz.; August, F. H. Snow. 

 One female. This individual is considerably larger than representatives of 

 the same sex from Salt Lake City, Utah, and San Diego county, Cal. 



Schistocerca vaga Scudder. 



Bill Williams Fork, Mohave-Yuma counties, Ariz.; August, F. H. Snow. 

 One male. 

 MelanopluB flavescens Scudder. 



Bill Williams Fork, Mohave- Yuma counties, Ariz.; August, F. H. Snow. 

 One female. I owe the identification of this specimen to Mr, A. N. Cau- 

 dell, who kindly compared it with United States National Museum material. 



Melanoplus flavidus Scudder. 



Bill Williams Fork, Mohave-Yuma counties, Ariz.; August, F. H. Snow. One 

 male. Mr. A. N. Caudell kindly compared this specimen and supplied 

 the above identification. 

 Clark county, Kan., 1962 ft.; June, F. H. Snow. One female. 

 Melanoplus canonicus Scudder. 



Bill WilliamsFork, Mohave-Yuma counties, Ariz. ; August, F. H. Snow. One 

 male, one female. The furcula of the male individual are more robust 

 apically than in Scudder's figure. 

 Melanoplus compactus Scudder. 



Clark county, Kan., 19G-2 ft.; June, F. 11. Snow. Two females. Previously 

 recorded from Dakota and Sheridan county, Neb. 

 Melanoplus minor Scudder. 



Clark county, Kan., 19G2 ft. ; June, F. H. Snow. One male, one female. 

 Melanoplus yarrowi Thomas. 



Bill Williams Fork, Mohave-Yuma counties, Ariz. ; August, F. H. Snow. 



One male, one female. 

 South Arizona; August, 1902, F. H. Snow. One male. 



These individuals agree well with a pair from Phcenix, Ariz. A female 

 specimen from Logan county, Kan., F. H. Snow, August, is doubtfully 

 referred to this species. The specimen is almost identical in structure, 

 and, if true yarrowi, considerably extends the range of the species. 

 Poecilotettix sanguineus Scudder. 



Bill Williams Fork, Mohave-Yuma counties, Ariz.; August, F. H. Snow. 

 One male, one female. 



Family LocustidjE. 

 Scudderia furcata Bruner. 



Douglas county, Kan., 900 ft.; September, V. L. Kellogg and E. S. Tucker. 

 Two males, five females. 

 Scudderia furcifera Scudder. 



Southern Arizona; August, 1901, F. H. Snow. One male, one female. Pre- 

 viously recorded in the United States from Prescott, Ariz. 

 Amblycorypha scudderi Bruner. 



Douglas county, Kan., 900 ft.; V. L. Kellogg. One female. This species was 

 described from eastern Nebraska. 

 Amblycorypha parvipennis Stal. 



Douglas county, Kan., 900 ft.; F. H. Snow. One male. This species was 

 previously known only from Texas.
