Eedescribed from the female type in the collection of W. J. 

 Chamberlin. 



Male. — Unknown. 



Type locality. — Lookout trail, 5,200 to 6,000 feet ; Fall Mountain, 

 Grant County, Oreg. 



DISTRIBUTION 



From material examined: 

 California: Mutau Valley (near Griffin P. O.), Ventura County, June 2, 1904 



(A. D. Hopkins). 

 Oregon : Lookout trail, 5,200 to 6,000 feet. Fall Mountain, Grant County, July 14, 

 1936, type (H. A. Scullen). 



Host. — Hopkins collected the adult and a pupa in a badly worm- 

 eaten, exposed root of a living Jeffrey pine (Pinus Jeffrey i "Oreg. 

 Com."). 



Very little variation was observed in the two females examined. In 

 the type the depressions are covered with a white efflorescence, which 

 is absent in the other specimen. The median lobe of the anterior 

 margin of the pronotum is exaggerated in Chamberlin's drawing 

 (fig. 19). Chamberlin states that the prominently lobed prosternum 

 readily separates the species from californica, but the lobe is very 

 narrow, and the species could be easily mistaken for one without a 

 median lobe on the prosternum, and the pronotum is not more than 

 twice as wide as long, as stated by Chamberlin.
