This large yellow and black species is most easily recognized by its 

 densely pubescent metanotum and propodeum, the latteir without 

 lateral teeth ; the left mandible has two teeth and the right three indis- 

 tinct ones. 



Description. — Yellow with black markings; vertex, all but lateral 

 margins of mesopraescutum and mesoscutum, mesal two-thirds of 

 axillae, mesal longitudinal mark on mesoscutellum, broad outer and 

 inner basal stripes of metacoxae, irregular area at base of metaf emora, 

 transverse basal stripe on propodeum, and transverse dorsal bands on 

 gaster, black. 



Female : 9-11 mm. Antennal scape constricted just ventrad of apex, 

 reaching level of posterior ocelli, pedicel slightly less than one-half 

 and ring segment one-sixth length of segment 4, segments 4 to 9 

 equal in length, 10 slightly shorter, 11 two-thirds length of 10, 12 and 

 13 together slightly longer than 11 ; scrobe cavity deep, edge carinate 

 only at ventral margin and ventral one-fourth of lateral margins, inter- 

 antennal projection wide, without an apical lamina; frons without 

 lateral carinae; frons deeply and densely punctured except on small 

 patch just dorsal to clypeus; frontal tentorial pits not visible; width 

 of malar space slightly less than one-third height of compound eye; 

 frontogenal suture extending in a low arc from compound eye to 

 dorsal articulation of mandible; width of interocular space at level 

 of antennal bases greater by one-fifth than combined widths of com-
