pubescent, the last visible abdominal sternite more elongate, arcuately emargi- 

 nate at apex, with the emargination limited at the bottom by a strongly deflexed 

 plate, which has the anterior margin of the plate arcuately emarginate and 

 entire, the eighth tergite more densely punctured, with a small median notch 

 at apex, and the anterior tibia unarmed at apex. 



Type locality. — Donner Lake, Placer County, Calif. Type in the

DISTKIBUTION 



From material examined : 



California: Donner Lake, Placer County, July 3-7, 1916, type series (R. T. 



Garnett). Meyers, August 8, 1915; Fallen Leaf, August 1, 1915 (F. B. 



Herbert). Yosemite, July 20, 1918; Crater Lake Park, August 1927 (J. E. 



Patterson). Truckee, August, 5,800 feet (H. F. Wickham).

Also recorded in the literature from the following* localities in 

 California: Independence Lake, Nevada County, July 12; Tahoe 

 Tavern, Lake Tahoe, July 12 ; Tuolumne Meadows, Yosemite National 

 Park, July 18-19, 1916, and Forest Hill, Placer County, April (Van 

 Dyke, 1918). 



Hosts. — Adults were reared from lodgepole pine (Pinus contorta 

 Loudon) collected at Crater Lake Park, Calif., by J. E. Patterson. 

 Adults were collected on western yellow pine {Pinus ponderosa Law- 

 son) and Jeffrey pine (Pinus jeffreyi "Oreg. Com."). 



Very little variation was observed in the few specimens examined, 

 except in the color in the depressed areas on the dorsal surface of the 

 body, which varies from bronzy green to reddish cupreous. The sides 

 of the pronotum are more strongly sinuate in some specimens than in 

 others. The length is from 11 to 13 mm. 



There will be some difficulty in separating the females of caurina 

 which do not have the prosternal lobe developed and the females of 

 falli. The females of both species have the emargination at the apex 

 of the last visible abdominal sternite limited at the bottom by a de- 

 flexed plate, but in falli this plate is usually strongly deflexed, with 

 the anterior margin of the plate arcuately emarginate and entire, 

 whereas in caurina the plate is usually only slightly deflexed, with the 

 anterior margin of the plate transverse and more or less dentate. Van 

 Dyke (1918) states that falli and caurina were collected in large 

 numbers at Donner Lake, and that falli somewhat replaces caurina in 

 the Middle and Southern Sierras and is there generally found in 

 company with monticola Fall.
