 pedicel, the first distinctly longer; club showing only two joints and 

 the apical spine; mesoscutum and scutellum reticulated, at the sides 

 and apex of the scutellum the reticulations becoming elongate ; meta- 

 notum at apex bounded by a carina, the disk rugose; propodeum 

 medially with a carina which anteriorly divides; lateral folds pres- 

 ent not very distinct; the area between them finely, almost reticu- 

 lately, rugulose; wings hyaline, the stigmal knob elongate, sub-
