Mountains on the same plant. At Cima it was found on small thorny 

 bushes, and at Las Vegas one small colony was located in a low thicket 

 of spiny desert bushes. 



The species was originally described from Los Angeles County, 

 California, and has since been recorded from Needles, California, and 

 Yuma, Arizona, by Bruner, and Yuma, Arizona, and Palm Springs and 

 Lancaster, California, by Scudder. Specimens from Yuma examined 

 by the present authors are clearly kunzei, and it appears probable 

 that the records from Yuma and possibly from Needles and Palm 

 Springs may be the same. True coquilletti appears to be a Mohavan 

 and Nevadan form. 



Arphia ramona Rehn. 



From the evidence of a series of eighteen specimens of this species 

 before us it is apparent that it enjoys a considerable vertical range and 

 also that it is considerably modified by the same. This series is from 

 the following localities: Pasadena, July 6, 1899 ((Fordyce Grinnell, 

 Jr.), two males; Mt. Lowe, August 8, 4,700 feet, one female, 5,300 to 

 5,600 feet, one male; Kenworthy, San Jacinto Mountains, 4,500 to 5,000 

 feet, June 3-8 (Fordyce Grinnell, Jr.), one male, three females; Straw- 

 berry Valley, San Jacinto Mountains, 6,000 feet, July 18 (F. Grinnell, 

 Jr.), one male; Santa Ana River, San Bernardino Mountains, 5,500 to 

 6,200 feet, July 1-14 (Joseph Grinnell), three males, one female; 

 Fish Creek, San Bernardino Mountains, 6,500 to 7,200 feet, June 17 

 to July 10 (Joseph Grinnell), one male, three females; Mt. Pinos, 

 Kern County, June 6, 1904 (F. Grinnell, Jr.), one female. 



When compared with the types from San Diego and a paratypic 

 series of two males and three females, the specimens from points under 

 6,000 feet elevation are seen to be very similar to the types, the tegmina 

 and wings alone being slightly longer in several of the mountain 

 specimens. The individuals from greater elevations than 6,000 

 feet show a perceptible reduction in size, which is very apparent when 

 the specimens are arranged serially according to altitude. There also 

 appears to be a slight flattening of the median carina of the pronotum 

 in individuals from the higher regions. 



The female specimen from Fish Creek, 7,200 feet elevation, measures 

 as follows: Length of body, 31 mm.; pronotum, 6.2; tegmen, 26; 

 caudal femur, 15.3. 



There is a considerable amount of individual variation in the general 

 color, this being blackish or brownish, strongly speckled or nearly 

 uniform, the pale stripe on the anal field of the tegmina also being 

 equally variable in its width, presence or absence.
