This series exhibits such a great amount of variation in size and 

 color, and to an extent in minor structural characters, that we have 

 not attempted to place the specimens in the four forms of the species 

 recognized by Scudder, as it appears probable that more than four 

 types must be recognized if all the variants are distinguished by name. 

 The desirability of doing this seems questionable, at least at the present 

 time. 



The smallest specimens in the series are from Summit House, Pasa- 

 dena and Altadena, while the largest are from El Toro, Alamitos Bay, 

 Merced and Raymond. One male and four females taken at Stanford 

 University, October 17, 1903, by Fordyce Grinnell, Jr., have also been 

 examined. 



Melanoplus aridus (Scudder). 



Three males and one female of this species were taken at Cima, 

 August 12. 



When compared with Florence, Arizona, individuals of both sexes, 

 the Cima specimens are found to agree ver} r fully in all points except 

 the position of the tegmina, these being attingent or at least sub- 

 attingent in the Arizona specimens and considerably separated in 

 the California individuals. 



This is the first record of the species from California. 



The specimens were taken in the tree yucca area where they were 

 scarce. They were found in a hilly location inhabiting the lowest 

 bushes. 



Melanoplus various Scudder. 



Four males and three females from elevations between 4,000 and 

 5,600 feet on Mt. Lowe, taken August 8 and 25, and a single female 

 from the slopes of the San Rafael Hills at Pasadena, taken August 1, 

 are provisionally referred to this species, described from specimens 

 from Tehachapi, Kern County, California, unique to this writing. 



The Mt. Lowe specimens appear to differ from the original descrip- 

 tion in having the furcula of the male hardly divergent, in fact parallel 

 in several of that sex, while the cerci appear to be slenderer at the apex
