slightly darker than dorsal portions. Lateral portions of ab- 

 domen often very dark, particularly in males. Cephalic and 

 median limbs buffy brown often suffused with darker. Caudal 

 femora dorsad with genicular area and two bands weakly darker 

 brown, external pagina with characteristic marking of this and 

 the allied species ; a broad V-shaped dark suffusion followed by a 

 very broad suffused vertical band, the intervening areas often 

 decidedly paler; internal surface with dorsal bands accentuated 

 and intervening areas pale, the pre-genicular area often buff, 

 below and ventral surface jasper red, the latter surface sometimes 

 paling to yellowish medio-longitudinally particularly proximad. 

 Caudal tibiae jasper red with a small proximal dark suffusion; 

 spines black, spurs buffy, black tipped. 



The similarity of color pattern to that of washingtonius and 

 oreophilus and of color as well in specimens from similar environ- 

 ment (the original series of washingtonius is recessive and pale, 

 probably due to aridity at the type locality) is remarkable, when 

 the very decided differences in the penis are noted.

A very gradual and slight decrease in size with increase in 

 elevation is shown by the different series taken from the base to 

 the summit of Strawberry Peak. The species was there every- 

 where scarce or very scarce except in extremely restricted spots 

 in a hudsonian mountain meadow surrounded by a very close 

 stand of Lodgepole Pines (the type locality). Its distribution
