higher specialization than that of those species. Definitely closer 

 affinity to repetinus, here described, is shown. 



The coloration of material of washingtonius from British Colum- 

 bia, unlike the original series of that species, agrees with that of 

 oreophilus in being darker with color pattern less sharply defined 

 and has the ventro-internal and ventral surfaces of the caudal 

 femora deep pink. These features are probably due to conditions 

 of immediate environment and have no diagnostic significance. 



The only material which has been subsequently secured is the 

 following : 



Okegon: Hood River, VII, 17, 1931, (R. H. Beamer), 1 d\ [Univ. of 

 Kansas]. Santiam National Forest, Cascade Mountains, (W. J. Chamberlin), 

 1 9 , [U. S. N. M.]. South rim of Crater Lake, Cascade Mountains, 7050 feet, 

 VIII, 26, 1928, (Hebard and Farrar; female in fine dry grass on slope of 

 volcanic ash, males on very small ridge of volcanic boulders in open thickly 

 clothed with alpine plants particularly Erigonum umbellatum Torr.; long 

 search failed to disclose other specimens; those taken were very sluggish)
