ICHNEUMON-FLIES, PART 2\ EPHIALTINAE 403 



Hoquiam, Wash. ; June 3 at Dardanelle, Calif. ; August 23 at Cimarron, 

 N. Mex. at 9,500 ft. and at Banff Loop, Alta. at 4,500 ft.; August 24 

 at Skagway, Alaska; and September 9 at Wellington, B. C. 



We have found the species common in various kinds of coniferous 

 woods, and among the above specimens are rearings from Picea 

 sitchensis, Pinus contoiia murrayana, and Abies lasiocarpa, but without 

 definite host records. 



This species occurs in the West, in coniferous forests from Alaska to 

 New Mexico, in the Hudsonian, Canadian, and Transition zones. 

 Adults occur mostly in the summer months. 



5. Rhyssa crevieri (Provancher) 



Figure 317,e 



Epirhyssa Crevieri Provancher, 1880, Naturaliste Canadien, vol. 12, p. 17 (Faune, 

 p. -4-49); o\ Type: d\ Quebec (Quebec). 



Front wing of male 6 to 10.5 mm. long, of female 9 to 17 mm. long; 

 apical edge of subgenital plate of male weakly convex, with a weak 

 median notch. The front wing of the male usually lacks the areolet. 



Face of male entirely white; temporal orbit white on its lower 0.8 ± , 

 the white never continuous across top of eye; flagellum with a wide 

 white band, or the band restricted in width in smaller males or some- 

 times absent in very small males; metapleurum with a white spot 

 except in some males, the spot prolonged forward along upper margin 

 of metapleurum so that it is subtriangular in shape; front and middle 

 coxae of male white, of female fulvous to blackish brown, mostly 

 white on outer side; hind coxa fulvous to blackish, sometimes with a 

 white mark on upper side of its constricted basal part, which rarely 

 may be prolonged on upper side of the main body of coxa as a narrow 

 streak; femora fulvous with the apex infuscate, often entirely infus- 

 cate in males and occasionally entirely infuscate in females; para- 

 medial white spots on fourth and fifth tergites of female about 2.0 

 as high as long. 



We have not been able to study the type of crevieri since 1941, and 

 at that time we had no clear distinction between this species and 

 lineolata. But on the basis of recent notes on the type supplied to 

 us by Gerd Heinrich, it seems very likely that crevieri is the present 

 species.
