to distinctly acute-angulate. The bluish cast of the wings was very 

 noticeable in flight. The previous records of the species are from 

 Needles, California, and Bill Williams Fork and Yuma, Arizona. 



Draootettix californicus Bruner. 



Four specimens apparently belonging to this species have been 

 examined in this connection. These are an adult male from Echo 

 Mountain, 2,700 to 3,500 feet, taken August 8; an adult male from 

 Hemet Peak, 7,065 feet, San Jacinto Mountains, taken June 4 by F. 

 Grinnell, Jr. ; an adult female from the South Fork of the Santa Ana, 

 6,400 feet, San Bernardino Mountains, taken July 20, 1906, by J. 

 Grinnell, and an immature female taken on Mt. Lowe, 4,300 feet, on 

 August S. In addition to these specimens typical material of the 

 allied species, D. monstrosus and plutonius, from the collection of the 

 U. S. National Museum have been examined. 



Logically D. californicus appears to be the intermediate connecting 

 the other types of the genus (plutonius and monstrosus) and at present 

 it is not clearly defined. The general form of the fastigium, shorter 

 proportionately in this than in the allied species, of the pronotal carina, 

 of the caudal femora, and the general appearance of the insect seem 

 to be the most useful points, the color of the internal face of the caudal 

 tibia? and the form of the accessory carina? on the occiput being of 

 little or no use. The material before us in addition to the above 

 listed specimens consists of the following : 



D. monstrosus, Los Angeles County, two males. San Diego, one 

 immature female. Claremont, one female. "Cal.," one female. 



D. plutonius, Panamint Valley, one male, type. Coso Valley, one 

 female, type. 



D. californicus, Claremont, one male. Mountains near Claremont, 

 one female. San Bernardino County, two males. 



Of the series of eight specimens of californicus before us, one male 

 from San Bernardino County and the San Bernardino Mountains 

 female have the internal face of the caudal tibia? uniform purplish, in 

 one male from the San Jacinto Mountains there is a trace of reddish 

 and in the remainder the red is marked, at least distad. 



The previous records of the species are from Santa Cruz Mountains, 

 Gilroy and Napa, California, and southern Arizona. 



Sohistocerca vaga (Scudder). 



A single male from Altadena, August 8, and two females from 

 Pasadena, taken April 23 and June 18, 1898, by F. Grinnell, Jr., are 

 in the series before us.
