 the Labenini and differs from Zachresta Foerster as represented by 

 Zachresta popofensis Ashmead especially in the cheeks being less than 

 haK as wide as the eyes, in the eyes converging below though not

 propodeum having only a basal and apical carina, in the hind 

 coxae being rather cylindrical and almost if not quite three times 

 as long as thick at the thickest portion, in the sessile, pentagonal 

 areolet, in the nervulus being as far beyond the basal vein as the 

 former is long, in the third abscissa of the discoidal vein being as 

 long as the second, in the nervellus being broken a little below the
