coarsely and distinctly punctate; notauli not at all indicated; 

 sciitellum longer than broad, strongly convex ; apical carina of pro- 

 podeum incomplete laterally, the apical pleural area not defined ; ab- 

 scissula more than half as long as intercubitella ; postpetiole only a 

 little broader than petiole; second tergite fully three times as long 

 as broad ; ovipositor sheath nearly a half longer than first segment. 



Black of posterior part of head reduced to a small median bilo- 

 bate spot widely separated from ocellar spot; all markings of 

 thorax the same as in convergens except smaller, and the U-shaped 

 mark of mesoscutum not confluent with scutellar spot ; abdomen with 

 same pattern but brown instead of black; scape and pedicel entirely 

 yellow, flagellum ferruginous with the apical fifth or sixth black; 

 front and middle legs without dark markings ; hind coxa yellow ex- 

 cept a spot of piceous on outer lower side, basal joint of trochanter

This Japanese species was only briefly described by Ashmead, and 

 the following is largely a statement of characters not mentioned by 

 him, but by which it differs from all the species described above: 

 Ocellar triangle very strongly transverse; malar space nearly as long 

 as basal width of mandible ; occipital carina curving sharply inward 

 to join hypostomal carina far behind base of mandible; thorax 

 strongly punctate throughout, propodeum rugulose apically and medi- 

 ally ; epomia strong and complete ; scutellum margined only at base, 

 its fovea margined anteriorly by a strong carina, foveolate; meso-
