386 NORTH AMERICAN MELANOPLI (ORTHOPTERA) 



there shows that it occurs from the conifer forests composed 

 largely of Western Yellow Pine upward to timber line conditions 

 among stunted stands of the White-bark Pine. 



The following eighty eight specimens have been studied : 



Oregon: Haines, VII, 10, 1931, (R. H. Beamer), 6 d", 5 9, [Univ. of 

 Kansas]. Washington Gulch, foothills of Elkhorn Range, Blue Mountains, 

 3800 to 4300 feet, VIII, 14, 1910, (Rehn and Hebard; one colony on steep 

 pine-clad hillsides, among scant undergrowth in which Spiraea petufolia was 

 predominant), 8 cf, 3 9. Four miles east of Summit, Whitman National 

 Forest, Blue Mountains, 4600 feet, VIII, 19, 1928, (M. Hebard; very rare in 

 undergrowth of Western Yellow Pine, Western Larch, fir and spruce forest), 

 2 cf, 1 9. Summit, Baker-Grant County line, Whitman National Forest, 

 Blue Mountains, 5095 feet, VIII, 20, 1928, (Rehn and Hebard; very scarce in 

 undergrowth of heavy conifer forest), 4 cf, 8 9. Strawberry Peak, Blue 

 Mountains, 8900 feet, VIII, 21, 1928, (Rehn and Hebard; extremely scarce 

 on gravel and rock fragments with small mountain plants among stunted 

 White-bark Pines, Pinus albicaulis, no other Orthoptera there or up to 9640 

 feet at summit), 1 c? 1 , 1 9 , paratypes: 8400 feet, (Hebard; in Lodgepole Pine 

 forest, Pinus contorta), 1 9, paratype. Middle Onion Patch, Strawberry 

 Peak, Blue Mountains, 8250 feet, VIII, 21, 1928, (Rehn and Hebard); very 

 scarce except locally in hudsonian mountain meadow surrounded by heavy 

 stand of Lodgepole Pine), 19 cf, 16 9, type, allotype, paratypes, 1 juv. 9. 

 Strawberry Peak trail, Blue Mountains, 7100 feet, VIII, 21, 1928, (Rehn and 

 Hebard; few in scanty patches of undergrowth in Western Yellow Pine forest, 

 Pinus ponderosa), 10 cf , 1 9 , paratypes. Strawberry Creek, Blue Mountains, 

 4450 feet, VIII, 20, 1928, (J. A. G. Rehn; one only seen in undergrowth of 

 conifer forest composed largely of Western Yellow Pine), 1 cf . 



Usually very scarce and always local, the large series was 

 assembled only after many hours of close search through favor- 

 able areas, made in an effort to secure all the species of short- 

 winged Melanopli present. Only at Washington Gulch was M. 

 indigens Scudder found in addition.

[cf , 9 ; northern slopes of Mount Hood, Oregon, 20 from 3290 to 7000 feet 



(above the latter solid snows).] 



The following corrections to our original comments must be 

 made. The species is much more closely related to washingtonius 

 than to montanus, but the penis is very distinct and shows far 



20 Incorrectly referred to this species, the series from Washington Gulch 

 in the Blue Mountains of eastern Oregon is here properly placed as the closely 

 related but previously unrecognized repetinus.
