ICHNEUMON-FLIES — GELINAE : MESOSTENINI 45 



positor oblique (figs. 327,a-f); wrinkling of mesopleurum just below sub- 

 tegular ridge mostly vertical or irrigular; parasites of Lepidoptera and 

 Symphyta 4 



3. Middle coxa largely or entirely fuscous; third flagellar segment about 3.5 as 



long as wide; wrinkling of metapleurum usually without a longitudinal 

 tendency; profile of upper edge of ovipositor a little more rounded at the 



nodus (fig. 327,g) 8. cimbcivorus (Cushman) 



Middle coxa entirely ferruginous; third flagellar segment about 5.3 as long 

 as wide; wrinkling of metapleurum with a longitudinal tendency; profile 

 of upper edge of ovipositor a little more angular at the nodus (fig. 327,h). 



9. mandator (Linnaeus) 



4. Temple with a prominent upper posterior swelling, at a place where the oc- 



cipital carina curves sharply from its dorsal, more horizontal, portion to 

 its descending portion; intercubiti strongly convergent anteriorly, the 

 areolet pentagonal; all coxae black ... 4. pallipennis, new species 

 Temple without an upper posterior swelling, the occipital carina evenly 

 curved; intercubiti parallel or weakly convergent, the areolet quadrangular 

 or subpentagonal 5 



5. Second and third tergites black; coxae ferruginous 6 



Second and third tergites entirely or largely ferruginous, or if rarely mostly 



or entirely black, then the coxae also black 7 



6. Mesoscutum mat and punctate, a median stripe on each of its three lobes 



polished and punctate; punctures on second tergite small, separated by 

 about 2.3 their diameter; tip of upper valve of ovipositor a little less stout 



(fig. 327,b) 2. alutarius, new species 



Mesoscutum entirely polished and punctate; punctures on second tergite 

 large, separated by about 0.6 their diameter; tip of upper valve of oviposi- 

 tor a little stouter (fig. 327,e) 3. montanus, new species 



7. Front wing 7.5 to 8.5 mm. long; propodeal crests very high; hind basitarsus 



stramineous; tip of ovipositor more slender (fig. 327,a). 



1. grandis, new species 



Front wing 3.0 to 7.2 mm. long; propodeal crests not unusually high; hind 



basitarsus light brown to fuscous; tip of ovipositor less slender (figs. 



327,e,f) 8 



8. Tip of upper valve of ovipositor with a sharp dorsal ridge from nodus to apex, 



not flattened near the apex; teeth on tip of lower valve of ovipositor not 

 so close (fig. 327, e) ; clypeus and central part of face rather strongly convex 

 and weakly punctate; mesopleurum usually less strongly punctate, some- 

 times hardly at all punctate; punctures on second tergite rather evenly 



distributed 5. abbreviator (Fabricius), some specimens 



Tip of upper valve of ovipositor with a sharp dorsal ridge near the nodus, 

 distinctly flattened dorsally near the tip; teeth on tip of lower valve of 

 ovipositor very close (fig. 327,f) ; clypeus and central part of face weakly 

 convex and rather strongly punctate; mesopleurum usually more strongly 

 and closely punctate; punctures on second tergite distinctly denser on its 

 median half than on its basal and apical quarters 9 



9. Base of hind tibia with a white band; punctures on center of face separated 



by about 1.5 their diameter 6, lophyri (Norton) 



Base of hind tibia without a white band; punctures on center of face separated 

 by about 0.3 their diameter 7. neodiprionis (Cushman)
