The measured specimens are all from Raymond. 



Three of the Raymond males and two of the females are extremely 

 pale in color, almost uniform straw-yellow in general tone, the pronotal, 

 tegminal and femoral maculations being of the very faintest character. 

 The wings of these pale individuals are either clear yellowish-hyaline 

 without any maculations or with very faint indications of the fuscous 

 cloud of the normal type. This yellowish phase is approached by 

 two of the Raymond females, the remainder, however, of both sexes 

 being of the normal type. 



The habits of this species have been described by the authors in a 

 previous paper. 11 



This species has been reported from the San Joaquin-Sacramento 

 Valley between Merced and Redding. 

 Dissosteira venusta (St&l). 



This species has been examined from a number of localities extending 

 from Miramar and San Diego to Mill Valley, California. The series 

 is distributed as follows: Miramar, July 31, ten d\ 7 9 ; Pasadena, 

 August 1, five cT , ten 9 ; Rubio Canyon, San Gabriel Mountains, 

 August 8, three cT ; Santa Catalina Island, August 3, four c?, seven 9 ; 

 Raymond, September 3, three cT ; Ahwahnee, September 3, one 9 ; 

 Miami, September 3, one 9 ; Summit House, September 3, three d\ 

 one 9 ; Sentinel, August 31, one d\ 



Specimens from the vicinity of Pasadena and Miramar are as a rule 

 larger than those from the other localities, resembling in this respect 

 specimens from San Diego. Santa Catalina Island individuals are 

 smaller than representatives from the adjacent mainland, while the 

 specimens in the Mill Valley series are appreciably smaller than the 

 southern Calif orni an mainland material. Specimens from the west 

 slope of the Sierras are very similar in size to Mill Valley individuals. 

 The following measurements may be of interest :
