rugulose or nigulose-granular; malar furrow usually distinct; clypeus 

 distinctly wider than long and hyperclypeal area about as long as 

 clypeus; anterior margin of clypeus medially truncate or practically 

 truncate, basal margin straight or slightly convex; cheeks convexly 

 rounded, the striae on same not crossing malar furrow onto face; 

 narrow area along posterior orbit sometimes very finely and densely 

 sculptured; head in front view more or less transverse; eyes reaching

 spatial wall along median longitudinal line of scutellum slightly 

 thickened; area along inner margins of parapsides very finely sha- 

 greened; suture separating prepectus from pronotum indistinct; axilla 

 with an elongate fingerlike extension running posteriorly along lateral 

 margin of scutellum, the base of this extension falling distinctly below 

 middle of axilla, the axilla more or less depressed or excavated imme- 

 diately above base of extension and with the portion immediately 

 anterior to extension not sloping toward latter; surface of axilla 

 completely sculptured and opaque or subopaque, and without con- 

 spicuous rugae immediately above base of extension; basal shallow 

 furrows on underside of apex of scutellum turniPig caudad medially; 

 mediolateral areas of propodeum finely rugulosely sculptured, not 

 depressed laterally but sometimes excavated more or less on each 

 side of the median carina; postmarginal vein occupjnng about one- 

 sixth or less than one-sixth the distance between end of marginal vein 

 and apex of wing in a straight line and about one-half to nearly two- 

 thirds the length of the marginal vein; wing hairs fairly dense and dark. 



Abdomen: Posterior face somewhat broader than long to longer 

 than broad; first tergite strongly transverse and usually more or less 

 sculptured, its anterior margin more or less elevated and apparently 

 truncate; third segment (second of the gaster) more or less distinctly
