Female. — Length, 6.5 mm. Head and thorax to a great extent dullish and 

 uniformly, finely roughened or granular; cheeks shining; internal margins of 

 the eyes nearly parallel; antenna' thirty jointed, scape and pedicellum together 

 as long as the first joint of the flagellum. Dorsulum with scarcely a trace of 

 parapeidal grooves; mesopleura with a faint, oblique channel bisecting the 

 sclerite, above which is another indistinct, oblique impression, on the lower por- 

 tion of the mesopleura on the anterior half and near the mesosternum is another 

 short impression; metathorax rather coarsely sculptured, almost rugose, basal 

 area apparently rectangular, almost obsolete, areola pentagonal, almost triangu- 

 lar, the apical sides very short, almost obsolete, apical margin only partly indi- 

 cated ; petiolarea broad angled below the middle, less than twice as long as the 

 greatest width in spite of the shortened areola: metapleura more finely sculp- 

 tured than the areas, apparently punctured; wings faintly brownish, almost 

 clear, stigma and nervures dark brown, the stigma paler than the nervures, first 

 abcissa of the radius not quite two thirds the length of the second abcissa, 

 areolet quadrangular, the sides subequal, petiolate, the petiole shorter than the' 

 shortest side of the areolet; transverse median nervure received beyond the basal 

 nervure, third abcissa of the discoidal nervure more than half the length of the 

 recurrent nervure. Abdomen dullish, petiole shining on the sides. Rather 

 thinly pubescent with short, silvery hairs that are most abundant on the meta- 

 thorax; face appearing bare superficially; ovipositor exeerted over one-third the 

 length of the abdomen. Black; mandibles, except at tip, and the four anterior

 tarsal joint and claws of both anterior and middle tarsi brown, posterior legs 

 with coxa? and femora rufous, first joint of trochanters largely black, second 

 joint yellow, posterior femora brown at tip, posterior tibite whitish at base, then 

 a narrow brown band, then a broad white band as broad as half the length of
