 in type ; eye hairy, ocelli elevated ; vertex smooth, polished, and flat ; 

 frons smooth, polished, impressed, and with a median longitudinal 

 carina ; face slightly less than twice as wide as long, smooth and pol- 

 ished, slightly elevated medially and with a very indistinct, short, 

 median ridge above; clypeus about 1.50 times as wide as long, smooth

 pronotum rugose ; median lobe of mesoscutum without a longitudinal 

 depression each side of median line ; notaulices distinct and f oveolate ; 

 mesopleuron smooth and polished, upper and lower grooves foveolate

 pression at the middle leading to the lower groove; anterior portion of 

 metapleuron smooth and polished, posterior portion rugose with an- 

 terior half plain ; propodeum rugose, the carinae high and distinct, and 

 the spiracle ovate. First abscissa of radius 1.50 times as long as that 

 of basal vein ; third abscissa of cubitus shorter than fourth ; recurrent 

 vein slightly longer than second abscissa of cubitus and about one-half 

 as long as second abscissa of basal vein ; nervulus postf ureal by about 

 0.33 its own length ; interanal vein absent. Second and fifth segments 

 of fore tarsus about equal; apex of hind tibia not expanded into a 

 flaring process ; inner spur of middle tibia longer than basitarsus, sec- 

 ond and fifth tarsal segments of middle leg about equal ; inner spur of 

 hind tibia about 0.80 as long as basitarsus, the basitarsus shorter than
