ICHNEUMON-FLIES, PART 2 1 EPHIALTINAE 159 



Female: Front wing 13 to 14 mm. long; first tergite about 1.50 as 

 long as wide; second tergite about 1.35 as long as wide; third tergite 

 with moderately swollen tubercles, polished and covered with mod- 

 erate-sized sharp punctures, separated by about 1.0 their diameter; 

 ovipositor sheath about 1.95 as long as front wing; tip of lower valve 

 of ovipositor as in figure 330, h. 



Black. Clypeus, mandible, and often a tinge on lower part of 

 cheek, ferruginous; maxillary palpus pale stramineous, its first seg- 

 ment mostly blackish; labial palpus brown; tegula stramineous; 

 mesosternum and lower part of mesopleurum often somewhat fulvous 

 or tinged with fulvous; front and middle legs fulvous, the middle 

 tarsus tinged with brown; hind coxa and trochanters fulvous; hind 

 femur dark brown, its base fulvous, its lower half more or less tinged 

 with fulvous; hind tibia fuscous, its basal 0.15 whitish, its lower 

 edge brown; hind tarsus dark brown. 



The mesepimeron completely covered with hair and the medially 

 thickened male antenna are recognition characters of this species. 



This species was described from a single male. The type is lost. 

 We have seen a second European male, from Prague (Vienna museum). 

 Comparison of this with a Nearctic male disclosed no basis for even 

 a subspecific separation of the Nearctic population.

 zone.
