external surface with the characteristic Melanoplid picturing of this color 

 weakly developed. Caudal tibiae medici blue, fading to buffy proximad, 

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

 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 Mountains, Inyo County, 

 8000 to 8371 feet, IX, 5 and 8, 1919, (Rehn and Hebard), 14 cf , 16 9 , type, 

 allotype and paratypes. 



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, but not taken, in Lone 

 Pine Canyon at an elevation of about 7500 feet. 



Melanoplus rehni 24 new species (Plate XVI, fig. 8; plate XVII, fig. 5.) 



This handsome species is related to M. usitatus 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 solid and broaden- 

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

 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 large in 

 proportion to the body bulk. This is particularly apparent in 

 rehni. 



Type. — cf; Glendale, Douglas County, Oregon. Elevation, 

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

 [Hebard Collection, Type no. 558.] 



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

 group. Vertex little produced, sulcation rather broad and not deep, though 

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