A A. Furcula very small, moderately stout. Cercus with disto- 

 ventral angle decidedly more broadly rounded than the 

 disto-dorsal angle, the dorsal and ventral margins of the 

 distal portion convergent due to definite obliquity of the 

 latter. Generally similarly specialized penis much heavier 

 and broader. Cow Creek, Lemhi Mountains, Idaho, from 

 4300 to 4400 feet lemhiensis new species 



Both species are grayish brown with darker markings not con- 

 spicuous, in general appearance closely resembling salmonis here 

 described except that the caudal tibiae are pale glaucous. Rela- 

 tionship, however, is not close either to that species or the simi- 

 larly grayish mottled but submacropterous kennicotti Scudder. 

 Both of those species have very different male genitalic speciali- 

 zation. 



Other features characterizing the group are the pad-like ovate 

 tegmina with blunt lanceolation suggested, the male with small 

 cerci which have the distal portion bent both inward and upward 

 and its external surface conspicuously impressed and concave and 

 male subgenital plate with a submarginal apical tubercle.

 pi. 11, fig. 8. [d\ 9 ; Salmon City, Idaho.] 



The original series was secured by L. Bruner, probably in the 

 foothills of the Salmon River Mountains west of the town, as it 

 was there that Rehn and Hebard first secured specimens, though 

 close search for the species at a number of localities nearer 

 Salmon City proved fruitless. 



Four males and two females of the original series, a pair being 

 paratypes, are in the author's collection, but the figured male was 

 selected as type by Rehn and Hebard in 1912, which specimen 

 was not returned to Bruner by Scudder and is consequently now 

 at the Museum of Comparative Zoology. 



The following additional material is before us: 



Idaho: Foothills of Salmon River Mountains just west of Salmon City, 

 4000 feet, VIII, 14, 1928, (Rehn and Hebard; very rare in area thickly covered 

 with sage brush and a few composites), 2 d\ 1 9 . Upper Canyon, Morgan 

 Creek, Salmon River Mountains, 6650 feet, VIII, 15, 1928, (M. Hebard; 

 small numbers in sage brush on hillsides, difficult to capture as the sage brush 

 was very large and thick), 1 d\ 1 9 .
