ICHNEUMON-FLIES, PART 2\ EPHIALTINAE 365 



FEMALES 



1. Clypeus convex; malar space about as long as, or longer than, basal width of 



mandible; temples, viewed dorsally, as long as, or longer than eyes; wings 



usually dark brown 1. texana (Cresson) 



Clypeus more or less flat; malar space definitely shorter than basal width of 

 mandible; temples, viewed dorsally, not as long as eyes; wings light brown 

 or hyaline 2 



2. Ovipositor with a strong dorsal curve apically (figs. 313,k,m). Japonica 



GROUP 3 



Ovipositor without a strong dorsal curve apically (figs. 313,1, o,p). Novita 

 group 4 



3. Ovipositor heavy, depth near apex greater than width of front tibia at its 



widest (fig. 313, m) 2. gelida, new species 



Ovipositor not heavy, depth near apex less than width of front tibia at its 

 widest (fig. 313, k) 3. japonica Cushman 



4. Ovipositor point • very gradually narrowed, tenuous, at least five or six times 



as long as its depth; apical third or more of hind femur fuscous or blackish. 



4. lepteces, new species 

 Ovipositor point much less gradually narrowed, not more than four times as 

 long as its depth; hind femur usually with much less than apical third fus- 

 cous or blackish (when, as in some specimens of novita, approximately the 

 apical third of hind femur is fuscous, then the white area of tibia is much 

 more extensive) 5 



5. Hind tibia and tarsus blackish, sometimes tibia pale at extreme base, tarsus 



entirely dark brown or blackish 5. borealis, new species 



Hind tibia with pale annulus at base and ventrally with varying amount of 

 pale color extending toward apex; tarsus with at least first segment pale at 

 base 6 



6. All abdominal segments more or less finely punctate . . 6. pfankuchi (Brauns) 

 Abdominal segments 1-3 more or less coriaceous or finely granular. 



7. novita (Cresson) 



1. Delomerista texana (Cresson)

The characters that quickly separate this species from all others in 

 the japonica group are the long malar space, convex clypeus and 

 temples, and the finely granular sculpture of the abdominal tergites. 



Further characters noted are: Small shallow punctures on face 

 separated by one to three times their diameter with none or very few 

 on central area; ovipositor sheaths varying in length from a little 

 more than half to a little more than two-thirds the length of abdomen. 



* That apical portion of ovipositor beginning where the depth of ovipositor changes its dimension and 

 narrows to apex, or slightly enlarges and then narrows to apex.
