Male. — Differing from the female in having the last visible sternite shorter, and 

 deeply, semicircularly emarginate at apex, the eighth tergite more deeply emar-

DISTRIBUTION 



From material examined : 



California: Wawona, June 11, 1904 (A. D. Hopkins). Onion Valley, reared 

 (H. E. Burke). Fallen Leaf, August 1, 1915 (F. B. Herbert). Bray, April 

 23, 1914 (J. D. Riggs). Yosemite, May 1931 (E. G. Linsley). 



Idaho: Coeur d'Alene, May 14, 1920 (J. C. Evenden). Fort Sherman, March 

 1896 (J. D. Riggs). 



Nevada: No definite locality (type series). 



Oregon: Cable Cove. July 27, 1911 (F. C. Craighead). Madera County, March 

 25 (R. Hopping). Fort Klamath (paratype). Crater Lake, July 4, 1939. 



Also recorded by Chamberlin (1926) from Grant County, Oreg., 

 during June and July, and from Weed and Yosemite, Calif. 



Hosts. — This species has been reared from white fir {Abies con- 

 color Lindley and Gordon) by Burke in California, and the adults 

 have been taken by various collectors on western yellow pine {Pinus 

 ponderosa Lawson) and Jeffrey pine {Pinus jeffreyi "Oreg. Com."). 

 Chamberlin (1926) records it from loclgepole pine {Pinus contorta 

 Loudon) and sugar pine {Pinus lambertiana Douglas), and (1917) 

 states that the species probably breeds in these pines. Beer (1940) 

 records it as reared from a limb of Douglas fir {Pseudotsuga taxifolia 

 (LaMarck) Britton) in Oregon. 



No variation worthy of note was observed in the specimens exam- 

 ined, except that the color on the underside of the body ranges from 

 reddish purple to purplish black. The length is from 10.5 to 14.5 mm. 



Horn described the species from California, Nevada, and Oregon, 

 but there are no specimens from California in either the Horn or 

 LeConte collections. Chamberlin (1926} selected the specimen from 

 Nevada as the lectotype.'
