raised as a paii* of strong longitudinal parallel ridges or elongate 

 tubercles, between these ridges and basally with long erect hairs. 



Black. Apical half of mandible rufous; wings infuscate. 



The male of this subspecies is indistinguishable from that of P. 

 nofha occidentis. 



Female: Forewing 4.5 to 7.5 mm. long; frons subpolished, with 

 rather coarse punctures separated by about 0.5 theh diameter. 



Black. Apical half of mandible rufous; wings strongly infuscate. 



Specimens (429): From Arizona (Mormon Lake and the Santa 

 Catalina Mts. at 5,500 ft., 6,000 ft., 7,500 to 8,500 ft., 8,000 ft., and 

 9,000 ft.); California (Berkelej^, Buck Creek in Modoc County, 

 Carmel, Felton, Lands End in San Francisco County, Mount Love 

 in San Francisco County, Mokel Hill in Calaveras Countj^, Mount 

 Tamalpais, Orick, hills back of Oakland, "Eedwood" in Marin 

 County, San Bruno, San Rafael, San Mateo, Tracy, and Yorkville); 

 Colorado (Rabbit Ears Pass at 9,500 ft.); New Mexico (Cloudcroft 

 at 9,000 ft.); Oregon (Klamath Lake); Washington (Forks); and 

 Mexico (meadow valley in the Sierra Madre). 



Most dates of collection are m June through August, or in the 

 warmer parts of the range, from May 15 through August. Dates 

 outside of the latter range are: May 1 at Yorkville, Calif.; May 7 at 

 Berkeley, Calif.; Sept. 21 at Tracy, Calif.; Oct. 1 at Carmel, Calif.; 

 and Oct. 27 at Berkeley', Calif. A number of males collected together 

 with these females make an unquestionable association of the sexes, 

 but they are indistinguishable from males of the subspecies occidentis. 

 Some additional males from the same general area as the females 

 represent additional specific localities, but are not reported because 

 they do not in themselves give proof of the distribution of the 

 subspecies. 



This subspecies occurs in the Canadian and Transition Zones from 

 the Pacific to the Rocky Mountains.
