Several specimens of this common and widely distributed species 

 from Grand Canyon of the Colorado (Skinner, July 11) are also in 

 hand. 



Trimerotropis cyaneipennis Bruner. 



Carr Canyon, Huachuca Mountains, August, 1905 (Skinner), 6 d^, 6 9 . 

 September 24, 1905 (Biederman), 6 (d, 4 9 . Palmerlee, September 

 (Schaeffer), 1 9 . 



Scudder's T. cijanea^- appears to be a synonym of this species. 



HADROTETTIX Scudder. 

 Hadrotettix trifasciatus (Say).

There is no doubt in the author's mind that Conozoa melleola is the 

 species later described by Caudell as Meslohregma gracilipes. A com- 

 parison of the descriptions shows the identity of the two species. 



HELIASTUS Saussure. 

 Heliastus benjamini Caudell. 



Carr Canyon, Huachuca Mountains, August (Skinner), 4 (d, 2 9 . 

 September 22 and 23, October 20 and 24 (Biederman), 3 d", 8 9 . 

 Palmerlee, August 7 (Schaeffer), 1 9 . 



This series shows that in general color some specimens are decidedly 

 grayish, while others are warm brown, the tegminal bars varying little 

 in intensity. In some female individuals the metanotum is slightly 

 more tumid than in others.
