of P. decumbens. It is not possible, at present, to be certain of its

 D. Townes (Townes). 2 cf, near Sonora Pass, 8,000 ft., Calif., July 6,

 derosa, Ashland, Oreg., Apr. 14, 1916, F. P. Keen (Washington). 



We have also a number of females which are probably this species, 

 but since females cannot be separated with certainty from those of 

 P. decumbens, they are not reported here. 



This species is transcontinental in the Transition and Canadian 

 zones.
