ameter; hairs on mesepimeron on its upper 0.4 ± in front, on its upper 

 0.6 ± behind, the rest bare; metapleurum with moderately large, 

 weak, dense punctures that are partially obscured by weak, irregular 

 wrinkling; petiolar area about 0.52 as long as combined areola and 

 basal area; propodeal teeth rudimentary, indistinct, about 0.2 as long 

 as wide at base; hairs in first lateral area rather dense; hind femur 

 about 1.87 as long as deep, with small, sharp, dense punctures all 

 over, the punctures a little coarser ventrally; second segment of mid- 

 dle tarsus about 1.7 as long as deep; fifth segment of hind tarsus about 

 1.2 as long as second segment; second tergite with moderately small, 

 sharp punctures that are separated by about 2.0 their diameter, in 

 some places a little sparser; surface of second tergite subpolished, more 

 or less rugulose basally; ovipositor sheath about 1.35 as long as front 

 wing. 



Black. Palpi brown; tegula blackish brown; legs fulvoferruginous, 

 the hind tarsus and upper half of hind tibia fusco ferruginous ; wings 

 hyaline. 



Females are recognizable by the black abdomen, fulvous legs, closely 

 punctate mesoscutum and second tergite, somewhat flaring temples, 

 and lack of a fuscous mark on apex of hind tibia. The species is very 

 close to O. canadense and may be only a western subspecies of it. 



Specimens (15 d 1 , 119): From British Columbia (Lorna, Pender 

 Harbor, and Robson) ; California (Camino, Crane Flat, near Glacier 

 Point, Tamarack Flat, and Yosemite Valley, all except Camino 

 in Yosemite National Park) ; Idaho (Priest River) ; Oregon (Sumpter) ; 

 Washington (Ashford and Mount Rainier at 2,900 ft.) and Wyoming 

 (Teton Pass). 



Dates of collection are mostly in July, but range from June 27 (at 

 Camino, Calif.) to August 31 (at Robson, B. C). 



There are two rearing records: 9, reared from "Tremex" in Abies, 

 Sumpter, Oreg., July 27, 1911, F. C. Craighead. 9 (type), from 

 Leptura obliterata in Abies grandis, Priest River, Idaho. 



This species occurs in the Transition and Canadian zones of the 

 West, from southern British Columbia to central California.
