 wide; pedicel a little over twice as long as wide, as wide as the sixth 

 joint at apex; third joint twice as long as wide, two-thirds as long 

 as the fourth and a little narrower; fourth twice as long as wide, a 

 little narrower than the pedicel; fifth as long and as wide as the 

 fourth, narrowed at both ends; sixth longer and wider, narrowed 

 basally; joints seven to nine subequal, wider, about one-half longer 

 than wide, the sides parallel; ten as wide as nine, conic-ovate, rather 

 blunt apically; thorax two-thirds as wide as long, a little narrower 

 than the head, strongly convex above, shining; pronotum aciculate 

 laterally, unsculptured before the tegulae; median area transverse, 

 slightly narrowed posteriorly, smooth and shining; mesonotum 

 strongly convex, finely shagreened toward the front, unsculptured 

 posteriorly, sparsely pubescent; notauli incomplete, indicated on 

 basal third of mesonotum ; median lobe broadly rounded behind as 

 in viticola; scutellum strongly convex, higher than the middle of the 

 mesonotum, margined laterally, smooth and shining, pubescent pos- 

 teriorly on the sides; metapleurae, propodeum, and first and second 

 sternite covered with short white pubescence; first and second ter- 

 gites not pubescent; abdomen longer than the head and thorax 

 united, narrower than the thorax across the tegulae, convex above 

 and below; median area on first tergite convex, not well defined, 

 with three longitudinal carinae, the dorsolateral ridges low; first 

 tergite roundedly elevated anteriorly, the elevated portion smooth, 

 the carinae stopping at its base; striae on second tergite reaching to 

 or a little beyond the middle of the segment ; tergites three to five 

 each with a row of punctures (interrupted medially) across it, hairs 

 rising from the pits; last tergite laterally and on posterior half with 

 long scattered hairs; wings hyaline, not quite reaching to the apex 

 of the abdomen. Black; antennae and legs dark brown, the tarsi 

 (except last joint of each) and anterior tibiae apically, lighter,

Male. — Length 1 .3 mm. Pedicel twice as long as wide, widest before 

 the apex, as long but not quite as wide as joint four; third joint 

 button-shaped, half as long and about as wide as the fourth; fourth 

 slightly narrowed basally, not emarginate, and not widened apically; 

 joints five to nine distinctly longer than wide, cylindrical, pilose; last 

 joint as long as the third and fourth united, conical; abdomen spat- 

 ulate, twice as long as wide, seven-ninths times as wide as the thorax 

 across the tegulae, about as long as the thorax; first and second ter- 

 gites more highly convex than in the female ; the striations on second 

 tergite fewer than in the female, shorter between the foveae; wings 

 extending the length of the head past the apex of the abdomen.
