flavidus and its allies, and little stress should be laid on its determina- 

 tive value. In measurements this individual differs from the original 

 only in that the caudal femora are one millimeter shorter than the 

 minimum there given. 



TETTIGONID^. 

 Arethaea constricta Bruner. 



Tucson, 1 ? , 



This sjiecimen is inseparable from Texas females of this species, and 

 constitutes the first record from west of the Organ Mountains, southern 

 New Mexico. 

 Scudderia mexicana (Saussure). 



Baboquivari ^lountains, 1 d^. 

 Eremopedes unicolor Scudder. 



Baboquivari Mountains, 1 cJ*. 



Huachuca Mountains specimens are usually smaller than this in- 

 dividual, which is very pale and buffy-brown in color. 

 Ateloplus notatus Scudder. 



Tucson, 1 9 . Baboquivari Mountains, 1 immature 9 . 



These representatives have been compared with a female from 

 Florence, Arizona, and show no differences except a more blackish 

 coloration. 



Gryllus armatus Scudder. 

 Tucson, 19. 



Miogryllus lineatus (Scudder). 



Tucson, 1 9 . 



This record is of very considerable interest, as no mature specimens 

 of this species have been recorded since the types were collected along 

 the Colorado River between Mohave City and the Virgin River. 



(Eoanthus californicus Saussure? 



Baboquivari Mountains, 2 9 . 



These specimens are assigned here with some little doubt, as they 

 have distinct blackish lines on the two proximal antennal joints. 

 However, in the shape of the femora, the color of the head and the 

 antennae, aside from the markings, they agree with males of this species, 

 while the pronotum has the sulci disposed in a similar fashion and 

 differs only in the lack of caudal expansion, a character which appears 

 to be sexual in this genus, due to the greater expanse of the male 

 tegmina. Some little affinity is shown with the recently described 

 CE. rehnii Baker, but the specimens are clearly distinct from that
