ICHNEUMON-FLIES, PART 2: EPHIALTINAE 199 



We have two females of Clistopyga sauberi Brauns, 1898, from 

 Germany which appear to be only subspecifically distinct from C. 

 canadensis. Reduction to subspecific status, however, would not be 

 wise till a longer series and males could be compared. 



Specimens (9d", 35 9): From Alberta (Slave Lake); Colorado (Glen 

 Haven); Maine (Bar Harbor, "Elizabeth," and Southwest Harbor); 

 Massachusetts (Middlesex Fells); Michigan (Alston, Dickinson Co., 

 Douglas Lake in Cheboygan Co., Iosco Co., Midland Co., and Twin 

 Lakes in Houghton Co.) ; Minnesota (Kawishiwi River) ; Montana 

 (Jefferson Island) ; New Brunswick (Nerepis) ; New Hampshire (Ran- 

 dolph); New York (Oswego and Rome); Newfoundland ("Harmon 

 Field"); Nova Scotia (Bridgewater, St. Peters, and White Point 

 Beach in Queens Co.); Ontario (Constance Bay and Moosonee); 

 Pennsylvania (Spring Brook) ; Prince Edward Island (Brackley Beach 

 in the Canadian National Park) ; Quebec (Cap Rouge, East Cape on 

 Anticosti Island, "Lake Island," Meach Lake, and Quebec); Sas- 

 katchewan (Atten Lake at Cut Knife and Swift Current) ; Wyoming 

 (Saratoga); and Yukon ("Snus"). 



Dates of collection are distributed from May 15 (at Ottawa, Ont.) 

 to September 15 (in Midland Co., Mich.), with most of them falling in 

 July and August. A female specimen from Meach Lake, Que., is 

 labeled as bred from Malacosoma disstria, July 27, 1951. Another 

 female from Bar Harbor, Maine, is labeled as having been bred from 

 lepidopterous bud worms on Picea by A. E. Brower, Aug. 4, 1938. 

 Since the genus Clistopyga is presumed to parasitize spider egg sacs, 

 these records are questionable. 



This species occurs in the Canadian zone and in the cooler part of 

 the Transition zone, from the Atlantic Ocean to the Rocky Mountains. 

 It is adult throughout the growing season, with most adults occurring 

 in July and August.

Clistopyga maculifrons Cushman, 1921, Proc. U. S. Nat. Mus., vol. 60, art. 4, 

 p. 10; 9. Type: ?, Texas (Washington). 



Front wing of male about 3.6 mm. long, of female 4.2 to 5.0 mm. 

 long; body of moderate stoutness; metapleurum polished, its posterior 

 half punctate; propodeum of moderate length, rather strongly convex, 

 mat medially, polished or subpolished marginally, its punctures rather 

 small and weak, its median longitudinal carinae represented by weak 

 ridges extending about 0.35 its length; basal half of ovipositor straight, 

 its apical half weakly upcurved. Otherwise similar in structure to 

 C. canadensis. 



Black. Small orbital mark at top of eye, face of male except 

 lower margin, orbital mark on face of female extending downward from
