external surface with the characteristic Alelanoplid picturing of this color 

 weakl}- developed. Caudal tibiae medici blue, fading to huffy proximad, 

 with a small and weak proximal dark annulus; spines black and spurs butly, 

 black tipped. 



The series shows little color variation. Some individuals are of a slightly 

 more buffy general tone of coloration, others slightly more grayish. 



Specimens Examined: 30; 14 males and 16 females. 



California: Lone Pine Canyon, Sierra Nevada iVlountains, Inyo County, 

 8000 to 8371 feet, IX, 5 and 8, 1919, (Rehn and Hebard), 14 cf ,V) 9 , type, 

 allotype and paratijpes. 



This species was found in open areas of the pine forest, on bare 

 soil of decomposed granite, where sage brush occurred in small 

 quantities and scanty grasses were found. Difficult to locate and 

 occurring in small colonies, the insect was found to be an active 

 and powerful jumper. It was first seen, Init not taken, in Lone 

 Pine Canyon at an elevation of about 7500 feet. 



Melanoplus rehni'-^ new species (Plate XVI, fig. 8; plate XVII, fig. 5.) 



This handsome species is related to M. Wiitatus Scudder. 

 Males differ in the much more extensive shining black area of 

 the pronotal lateral lobes, the slightly greater production and 

 angulation of the caudal margin of the pronotal disk and the 

 more elongate supra-anal plate and cerci, which latter are further- 

 more not decidedly narrowed distad. 



Both sexes differ in the proportionately slightly longer prono- 

 tum. The majority of the females have the lateral lobes of the 

 pronotum with a broad dark band, this band soUd and broaden- 

 ing caudad; a few, however, lack this marking. In u.sitatm 

 females have traces of such a marking, but these are irregular 

 in ventral outline and are narrower in the metazonal than in the 

 prozonal portion. 



The species of this group all have the head unusually lai'ge in 

 proportion to the body bulk. This is particularly apparent in 

 rehni. 



Type. — d^; Glendale, Douglas County, Oregon. Elevation, 

 1500 to 1900 feet. August 12, 1909. (Reim and Hebard.) 

 [Hebard Collection, Type no. 558.] 



Size large for the group, medium for the genus; form medium for tlie 

 group. Vertex little produced, sidcation rather broad and not dcei), though 

 more decided than in usitatus, frontal costa shallowly concave from above
