366 U. S. NATIONAL MUSEUM BULLETIN 216 



The male may be further identified by the black or blackish coxae 

 and trochanters, black face with pale clypeus and pale or white tri- 

 angular area on each side of face. In one specimen from Great Whale 

 River, Que., this area is so dark as to be barely discernible. 



Females vary in length from 7.5 mm. to 10.5 mm., males from 5.5 

 mm. to 9.7 mm. The Nearctic specimens generally have darker 

 wings, blacker hind tibiae and almost buccate temples. However, a 

 European specimen from "Abisko, Lapland, North Sweden," sent to 

 me by J. F. Perkins of the British Museum (Natural History) has 

 darker wings and hind tibiae than a specimen taken at the same 

 locality earlier by J. R. Vockeroth, Ottawa, Ont., while a male and 

 female from Chesterfield, Northwest Territories, both have hind 

 tibiae the same reddish color as the femora and have the hind tarsi 

 only slightly darker. The wings, too, are lighter. 



Distribution: Europe; Alaska; Canada: Quebec (Fort Chimo and 

 Great Whale River), Northwest Territories; United States: New 

 Hampshire, Maine. 



Host: Unknown. 



2. DeTomerista gelida Walklcy, new species 



Figures 3 13,m; 316,j 



This species has been misidentified in collections as D. texana. It 

 can be readily distinguished, however, by the difference in abdominal 

 sculpture (the abdomen being mostly coriaceous rather than granular), 

 by the more robust ovipositor, shorter malar space, and flat clypeus. 



Holotype female: Body, 10 mm.; ovipositor sheaths, 4.3 mm. 



Head: Finely punctate; face with the punctures separated usually 

 by a distance less than, and never more than, the diameter of the 

 punctures; malar space not more than half basal width of mandibles; 

 temples somewhat convex but not as long as the eyes; clypeus flat, 

 emarginate; antenna with 32 segments. 



Thorax: Length to width as 4 to 3; sternauli reaching only to disk, 

 mesopleurum finely, sparsely punctate, polished; areola of propodeum 

 only a little longer than wide; costulae not complete; metapleuron 

 smooth and finely, sparsely punctate; dorsum of propodeum somewhat 

 reticulate, rough only in comparison with metapleuron. Wings with 

 slight brownish tinge; ramellus short, with color line extending well 

 into discocubital cell ; tegulae largely brownish. 



Abdomen: Length nearly 7 mm.; first segment dorsally rugose, 

 except on disk which is more coriaceous; second tergite somewhat 

 granular in sculpture and about % wider at apex than its length; 

 remaining segments mostly coriaceous; silvery pubescence of ab- 

 dominal tergites longer laterally than dorsally; blackish chitinous 

 areas on second abdominal sternite at least twice as long as wide, those
