 pleuron, propodeum, and ovipositor sheath, black; metanotum black- 

 ish, eye grayish black ; mouth parts black ; wings fuliginous, costa and 

 stigma ferruginous ; legs ferruginous, with coxae and trochanters and 

 usually anterior and middle femora basally, black, tarsi brown or 

 blackish. Antenna usually with 31 to 33 segments; eye bare; ocelli 

 elevated, vertex sm.ooth and polished ; f rons smooth and polished, with 

 a small depression below the anterior ocellus and with a median longi- 

 tudinal keel ; face about 2.50 times as wide as long, punctate, polished, 

 and with a small median tubercle above; clypeus punctate, its basal 

 median part slightly elevated, its apical margin slightly flaring, not 

 notched ; temple bulging, wider than eye in dorsal view ; galea long and 

 slender, about as long as the long axis of eye, tapering apically. 

 Median part of lateral face of pronotum weakly rugose ; median lobe 

 of mesoscutum flat, smooth and shining like lateral lobes; notaulices 

 moderately foveolate; mesopleuron closely, finely punctate, upper 

 groove coarsely foveate, lower groove foveolate, posterior groove 

 coarsely foveate; metapleuron punctate, rugose at apex; propodeum 

 rugose, carinae defining areola prominent, the costulae often indis- 

 tinct, spiracle long ovate. First abscissa of radius longer than that of 

 basal vein ; third and fourth abscissae of cubitus about equal ; second 

 abscissa of cubitus slightly longer than recurrent vein ; nervulus post- 

 f ureal by about 0.67 its length; first abscissa of submedius slightly 

 shorter than second ; interanal vein represented by a short stump con- 

 tinued by a pigmented line. Fifth segment of fore tarsus longer than 

 second ; apex of hind tibia thickened on outer margin and expanded 

 into a flaring process ; inner spur of middle tibia about 0.67 as long as 

 basitarsus, and second tarsal segment slightly shorter than fifth ; inner 

 spur of hind tibia about half as long as basitarsus, basitarsus shorter 

 than the next four tarsal segments combined, second and fifth tarsal 

 segments about equal; hind tarsal claws pectinate, with short teeth 

 basally. First abdominal suture slightly curved to the margin; sec- 

 ond tergite shorter than third medially; hypopygium in profile 

 pointed, about as long as the first three tergites combined ; its median 

 ventral line without a longitudinal fold; ovipositor sheath polished, 

 spatulate, pubescent at tip, its exposed part about 0.75 as long as 

 hypopygium (pi. 5, fig. 35).
