 trad of level of ventral margins of compound eye; apex of scape 

 not quite reaching level of anterior ocellus; first funicle segment 

 two-thirds as long as pedicel, second segment four-fifths as long as 

 first, third three-fourths as long as second, club short, globose, twice 

 as long as second funicle segment; length of malar space one-half 

 height of compound eye; malar furrow straight; length of posto- 

 cellar line twice as great as ocellocular. Mesopraescutum slightly 

 wider than long and its entire surface densely covered with bristles, 

 as in figure 19, e; submarginal vein of forewing with two or three 

 dorsal bristles; marginal vein three and one-half times as long as 

 stigmal; apex of hindwing blunt, fringe at posterior margin one- 

 sixth as wide as wing at hamuli. Surface of propodeum faintly 

 reticulated, almost smooth, paraspiracular carinae wanting, mesal 

 length of propodeum one-third length of mesoscutellum, propodeal 

 spiracles contiguous with anterior margin; gaster one and one-half 

 times as long as thorax. 



Male. — Length, 1.1-1.5 mm. Scape twice as long as pedicel, first 

 funicle segment four-fifths as long as pedicel, second segment equal to 

 first, third three-fourths as long as second, fourth one-sixth shorter 

 than third, funicle segments without conspicuously long bristles,
