Orphulella affinis Scudder. 



At Alamitos Bay, July 31, this species was found common among 

 the scant grasses of the beach dunes, while at South Coronado Beach, 

 August 16, it was secured among low salt marsh plants. Nine males, 

 five females and one immature specimen were taken at the former 

 locality and two adults of each sex and four immature individuals at 

 the latter. 



A moderate amount of variation in size in both sexes is presented 

 by the Alamitos Bay series. All the specimens are in the brown 

 phase except three males from Alamitos Bay and one immature speci- 

 men from South Coronado Beach. 



The species is now known from San Diego, South Coronado and 

 Coronado Beach, Alamitos Bay, Kern City and "Colorado Desert," 

 California. 



Napaia graoilis McNeill. 



This interesting species was found at an elevation of 4,000 to 4,800 

 feet on Mt. Lowe, August 8, where it lives among grasses, leaping and 

 crawling about actively. The wings are not used for flight, serving 

 the sole purpose of stridulating organs in the male sex. The stridula- 

 tion is quite like that of Chorthippus curtipennis, but much louder. 



A series of six males and seven females was taken, and but little 

 variation in size and color is to be noticed. The insect appeared to 

 be extremely local and was found in but one location between two 

 small mountain slopes. 



The species is known from Mt. Wilson, 2,400 feet, and Mt. Lowe, 

 4,000 to 4,800 feet, the San Gabriel Mountains near Claremont, at 

 Claremont and Los Angeles, California.
