NO. 2334. NORTH AMERICAN ICHNEUMON-FLIES— CUSHMAN. 255' 



large, broad oval, nearly parallel within, the inner orbits above 

 slight]}^ tumid; face densely finely punctate, slightly elevated medi- 

 ally; clypeus set off by a broad groove, with a transverse apical 

 impression extending entirely across, the apex broadly truncate, 

 leaving a distinct opening between it and the mandible; mandibles 

 narrowed at apex, equally bidentate; basal joints of flagellum long 

 and slender, the first slightly longer than second, this distinctly 

 longer than third, others gradually decreasing in length to near apex 

 where they are quadrate, the flagellum attenuate at apex. Thorax 

 coarsely sculptured throughout; pronotum laterally rugose, epomia 

 distinct nearly to dorsal margin, which is slightly tumid; mesoscu- 

 tum densely, confluently punctate, notauli distinct, subfoveolate 

 (the pin obscures the posterior ends of the notauli, but they are sharp 

 at least halfway back on the mesoscutum) ; scutellar fovea deep and 

 with a few longitudinal striae; scutellum sparsely punctate, its 

 lateral areas strongly longitudinally striate; postscutellum medially 

 bifoveate, its lateral areas striate; mesopleurum rugoso-punctate 

 above, densely punctate below, sternauli incomplete but deep, foveo- 

 late, curved dorsally; sternum densely punctate; prescutal carina 

 complete; metapleurum and propodeum coarsely rugoso-punctate, 

 the latter with short, blunt apophyses, behind which the surface is 

 very coareely reticulate ruguse, areolation nearly complete, only the 

 lateral longitudinal carinae being entirely wanting; nervulus slightly 

 antefiu'cal ; areolet pentagonal, sides slightly convergent, the inter- 

 cubiti forming the longest sides; second recurrent straight, with a 

 single broad bulla; nervellus broken far below middle, slightly 

 inclivous; legs slender. First tergite polished, spiracles at apical 

 fourth, petiole slender, postpetiole about four times as broad as 

 petiole, dorsal carinae wanting, lateral carinae complete to apex; 

 second and third tergites broad, strongly arched, callose at apex, 

 densely, finely punctate; other tergites short, subpolished; ovi- 

 positor sheath about one and one-half times as long as first tergite. 

 Head black, orbits except narrow interruption in malar space, 

 spot on clypeus, and spot on each mandible yellow; antennae black, 

 with an incomplete white annulus on flagellar joints 6-11. Thorax 

 black above, mesosternum and lower pleura, metasternum and 

 pleura ferruginous, this color extending above bases of apophyses; 

 anterior and superior margins of pronotum, two short lines on middle 

 of mesoscutum, scutellum largely, a line on dorsal margin of meso- 

 pleurum and a spot just above sternaulus, an obscure spot at base 

 of hind wing, upper portion of metapleurum, and the sides of the 

 posterior face of the propodeum including the apophyses yellowish; 

 legs testaceous; front and middle coxae in front and their basal 

 trochanters apically and ventrally white; hind tibia at apex, basi- 

 tarsus at base, and apical tarsal joint fuscous, tarsus otherwise white;
