Conozoa oarinata Kelm. 



Babo(.}uivari .Mountains, 2 d^, 1 ?. 



These specimens fully agree with the typical series from the Hua- 

 cliuca Mountains, Cochise Co., Arizona. 

 Trimerotropis fasoicula McNeill. 



Baboquivari Mountains, 1 cJ^. 



In coloration this specimen is slightly paler than Huachuca Moun- 

 tains representatives, with the internal and ventral faces of the caudal 

 femora suffused with the same red color as the tibiae, while the dorsum 

 of the abdomen has a wash of the same color. The general size is 

 slightly larger than Huachuca specimens and the proportionate length 

 of the tegmina is about the same, much longer proportionately than 

 in the type individuals. 

 Heliastus aridas (Bruner). 



Tucson, 1 9 . 



Heliastus benjamini Caudell. 



Baboquivari Mountains, 1 d^, 1 ? . 



The previous localities for this species are Nogales and the Huachuca 

 Mountains, Arizona. The male is more ferruginous than any other 

 specimen examined by the author. 

 Schistooeroa vaga (Scudder). 



Tucson, 1 d'. 



This individual is small and rather paler than the majority of sjDeci- 

 mens of this species. The amount of color variation presented by 

 individuals of this form is very considerable, the extremes having 

 quite different appearances but being connected in any series by 

 members of intermediate specimens. 

 Conalcaea huachucana Rehn. 



Baboquivari Mountains, 1 9 . 



This specimen is inseparable from the female type, and is the first 

 record of the species beyond the limits of the Huachuca Mountains. 



Hesperotettix festivus Scudder. 



Tucson, 1 9 . 



This individual has the pregenicular annuli very distinct, but shows 

 no traces of the blackish pencilling of the pronotal sulci seen in H. 

 viridis. 

 Melanoplus brownii Caudell. 



Baboquivari Mountains, 1 9 . 



This specimen appears to belong to this species which was described 

 from near Yuma, Arizona. Coloration counts for very little in M.
