Melanoplus atlanis (Riley). 



November 18-24, 1903. 7 d", 3 9. 



These specimens are quite large when compared with Eastern speci- 

 mens, a fact which is true of Florence, Arizona, individuals. 



Melanoplus differentialis (Thomas). 



September 4, October 16, 1904. 5 6^,1 9. 



TETTIGONID^. 

 Hormilia elegans Scudder. 



September 5-7, 1904. 2 d" , 6 ? . 



Three of the females present the type of coloration which has the 

 dark areas of the tegmina large and deep in color, surrounding and 

 isolating the light greenish portions. In this type the pronotum is 

 richer in color, owing to the more definite whitish margins contrasted 

 with the broad dark area which is placed on the caudal section of the 

 pronotal disk, and also in the patch on the lateral lobes being larger 

 and more conspicuous. One specimen is extremely pale, the dark 

 markings being weak or mere suggestions of color.

Allied to C. pacificus, hen- 

 shawi and salebrosus Scudder, 

 but in most every character 

 closer to salebrostis^^ than to the 

 others. From this it differs in 

 the nearly smooth abdomen, 

 the greater size, the different 

 proportions of the caudal tarsal 

 joints (second twice as long as 

 the third), the different charac- 

 ter of the serrations on the lam- 

 ellate ventral carinae of the 

 caudal femora, the longer cau-
