ICHNEUMON-FLIES, PART 2! XORIDINAE 473 



about 2.35 as long as high; upper 0.3 ± of pronotum with fine punc- 

 tures that are separated by about 3 times their diameter; trough of 

 pronotum with about 7 short, weak, transverse wrinkles, postero- 

 ventrally with some short, weak, horizontal ridges; punctures on 

 mesoscutum fine, moderately sharp, separated by about 1.5 their 

 diameter; mesepimeron with hairs on its upper 0.85 ± ; metapleurum 

 with medium sized, weak, moderately close punctures that are more 

 or less obscured by weak, irregular wrinkling, sometimes rather smooth; 

 petiolar area about 0.43 as long as combined areola and basal area; 

 propodeal teeth about 0.5 as long as their basal width; hairs on first 

 lateral area sparse, their sockets separated by about 1.2 the length of 

 the hairs; hind femur about 2.12 as long as deep, with very fine, weak, 

 dense punctures all over, the punctures a little sparser ventrally but 

 still moderately dense; second segment of middle tarsus about 1.5 as 

 long as deep; fifth segment of hind tarsus about 1.32 as long as second 

 segment; second tergite rather strongly mat, usually also with more or 

 less distinct fine wrinkling that is irregularly transverse, its punctures 

 not distinct, its hairs separated by about 2.0 their length; ovipositor 

 sheath about 1.08 as long as front wing. 



Black. Palpi fulvous to dark brown; tegula blackish; legs fulvous, 

 sometimes with faint fuscous tinges, the tarsi brownish apically and 

 hind tibia more or less infuscate, especially its dorsal half; wings 

 subhyaline. 



The female is distinctive in its small size, black abdomen, fulvous 

 legs, hairs near lower edge of hind femur moderately dense, punctures 

 on mesoscutum neither dense nor sparse, mat second tergite, head 

 relatively narrow across the temples, and lower part of pronotal 

 trough without long horizontal wrinkles. It is most similar to sierrae. 



Type: 9, Phantom Valley at 9,400 ft., Rocky Mountain National 

 Park, Colo., Aug. 9, 1948, H., M., D., and J. Townes (Washington, 

 USNM 63727). 



Paratypes (41 cf, 259): From British Columbia (Cultus Lake and 

 Robson); Colorado (Phantom Valley in Rocky Mountain National 

 Park at 9,400 ft.); Idaho (Moscow Mt.); Oregon (McMinnville) ; 

 Washington (Ashford, Blaine, Elbe, Glacier, Kamiak Butte in Whit- 

 man Co., Port Gamble, and Pullman); and Wyoming (Mammoth 

 Hot Spring in Yellowstone Park). 



Collection dates are mostly from July 4 to August 19. Those 

 outside this range are: April 1 at Kamiak Butte, Whitman Co., Wash.; 

 May 18 at Robson, B. C; June 8 at Moscow Mt., Idaho; and August 

 23 and 24 at McMinnville, Oreg. In our own collecting we have found 

 the species on herbage in moderately damp woods. 



This species occurs in the Canadian and Transition zones from 

 British Columbia to Oregon and Colorado.
