This species has been definitely recorded from San Diego, Claremont 

 and Guadelupe, California. 

 Conozoa salcifrons (Seudder). 



At Las Vegas, Nevada, a series of ten males and ten females of this 

 species was taken on August 10, while a single male was collected at 

 Indio on July 29. 



When compared with a considerable series from Yuma, Arizona, 

 no differences are noticeable. 



The previous Californian records of the species were from near the 

 Mohave River (type locality) and Indio. No Nevada records have 

 previously been published. 

 Trimerotropis cristata McNeill. 



Two males and two females of this very pale colored species were 

 taken, August 10, at Las Vegas, Nevada, in typical desert surroundings. 



The specimens are quite uniform in coloration and size. 



The previous records of the species are from San Julio, Lower 

 California, and Salt Lake Valley, Utah. 



Trimerotropis albolineata (Bruner). 



Three females of this species were taken in the Arroyo Seco at 

 Pasadena, August 1, while a single male was secured at Beaumont, 

 Riverside County, California, on July 30. Two females taken at 

 Pasadena, June 21 and July 1, by Fordyce Grinnell, Jr., have also been 

 examined. 



Some individuals are much more ferruginous than others, and the 

 pattern of the lateral lobes of the pronotum is fainter in one of the 

 Pasadena specimens than in the other individuals examined. 



This species is now known from Los Angeles, Pasadena, Ontario, 

 San Bernardino County, Beaumont, Riverside County, and San Diego, 

 California, and southern Arizona.
