NEARCTIC STEPHANIDAE — TOWNES 369 



laterally, dark ferruginous; wing weakly infumate, the forewing 

 marked with brown along the veins near the outer end of the brachial 

 cell ; abdomen ferruginous basally, shading to dark ferruginous api- 

 cally ; ovipositor sheath with a preapical white band. 



Paratype male : Similar to the type female but smaller (forewing 

 6.5 mm. long) and with weaker sculpture and the punctures less reg- 

 ularly formed. The punctures on the lower 0.5 of the temple are al- 

 most obsolete, and the pair of high sharp carinae on each side of the 

 front end of the pronotum are almost transverse rather than strongly 

 oblique. The first tergite is 10 times as long as wide and almost 

 smooth.

 hand. 



Forewing of male 8 mm. long, of female 9-16 mm. long; temple 

 polished, in larger specimens with large irregular punctures behind 

 the eye; pronotum polished, subbasally with a strong swelling that 

 bears coarse irregular punctures, medially with a raised transvei^se 

 area that is coarsely rugoso-punctate, and apically with about four 

 high sharp transverse carinae, some of which are usually interrupted 

 medially (pi. 25, fig. T) ; mesopleurum polished, with large round 

 punctures separted by about 0.7 their diameter ; propodeum polished, 

 with rather close large round punctures; brachial and subdiscoidal 

 veins distinct ; outer face of hind femur polished, with a very few fine 

 shallow punctures ; hind tibia of female sharply pinched at its basal 

 0.35, just beyond this with a sharp rounded dip in its anterior face; 

 apical half of female hind tibia swollen to the width of the hind 

 femur; hind basitarsus of female about 3.0 as long as wide, strongly 

 expanded apically; first tergite polished, with rather coarse cross 

 ridges, in the female about 6.0 as long as wide ; ovipositor sheath about 

 1.1 as long as the body.
