 in a direction to place the lower tooth of mandible nearer mouth 

 opening; mandible evenly tapered from base to apex, its outer face 

 moderately convex, with scattered punctures, its teeth moderately 

 large; second lateral area of propodeum with a few hairs laterally and 

 apicolaterally; front spur of hind tibia about 2.65 as long as wide in 

 male, about 2.5 as long as wide in female; punctures of second tergite 

 of moderate size and sharpness, very sparse or absent medially, the

 anteroventral edge of pronotum, lower part or most of propleurum, 

 tegula, subtegular ridge, narrow apex and narrower side of scutellum, 

 and usually postscutellum, ivory; flagellum tan beneath in male, 

 brown beneath in female; male mesosternum almost entirely and 

 mesopleurum and side of pronotum largely, ivory, the rest of meso- 

 pleurum and pronotum fulvous except for blackish area below sub- 

 tegular ridge; male metapleurum fulvous and ivory; male scutellum 

 fulvous bordered with ivory; female pronotum usually largely fulvous 

 with its anterodorsal part black, sometimes entirely black except for
