ICHNEUMON-FLIES, PART 2 : EPHIALTINAE 93 



("Crystal Lake"); New Hampshire (Franconia and Randolph); New- 

 Jersey (Burlington, Glen Moore, New Brunswick, and South River) ; 

 New York (Greene Co. and Ithaca) ; Ohio (Puritas Springs in Cuyahoga 

 Co.); Ontario (Ottawa and Toronto); Quebec (Aylmer); Pennsylvania 

 (Chambersburg, Harrisburg, Manchester, and Stewartstown) ; West 

 Virginia (Kearneysville) ; and Wisconsin (Madison and Rib Mountain 

 State Park). 



All but 1 male and 10 females were reared, probably indoors, thus 

 giving little information about the natural season of the adults. The 

 collected specimens include a male taken August 3 and females on May 

 12, June 7 and 14, "June," "July," August 10, 21, and 27, September 

 5, and "Sept." 



Rearing records are: 1 from Canarsia ulmiarrosorella, 4 from over- 

 wintering cocoons of Carpocapsa pomonella, 1 from C. pomonella, 13 

 from overwintering cocoons of Grapholitha molesta, 1 from G. molesta, 

 and 1 from "bleeding Pinus." 



This species is in Ontario, Quebec, and the northeastern United 

 States. It parasitizes lepidopterous cocoons under scales of bark of 

 deciduous trees. 



3. Apistephialtes masoni, new species 



Male: Unknown. 



Female: Front wing 6.0 to 7.7 mm. long; propodeum a little rugu- 

 lose near position of median longitudinal carinae, its punctures of 

 medium size, the sublateral ones separated by about 1.0 their diam- 

 eter, those near position of median longitudinal carinae more crowded; 

 ovipositor sheath about 1.7 as long as front wing; ovipositor tip as in 

 A. variatipes (fig. 329,f). 



Black. Maxillary palpus, tegula, and line on upper margin of 

 pronotum extending from the hind corner about 0.6 the distance to 

 notaulus, white; labial palpus pale brown; legs fulvous, the apical 

 0.6 ± of last segment of front tarsus infuscate, middle tarsus weakly 

 infuscate with its apex dark fuscous, apex of hind femur rather nar- 

 rowly infuscate, hind tibia fuscous with its base a very little paler, 

 and hind tarsus fuscous. 



It is possible that this will prove to be only a subspecies of A. 

 variatipes.
