AUT. 15\ EEYISION OF SUBFAMILY PLATYGASTERINAE FOUTS. 15 



cheeks flattened, striate; frons finely aciculate, with a few striae 

 above the antennae; pedicel less than twice as long as wide, as 

 wide as joint five, wider than three, as long as three and four 

 united; four as long and as wide as three, about as long as wide; 

 five twice as long as wide, as long as the three preceding joints 

 united, as wide as six; six not quite as long as five; seven to ten 

 subequal in length and width, longer than wide; ten subacute apically, 

 the sides rounded; thorax less than twice as long as wide, flattened 

 above, higher than wide; pronotum unsculptured, sparsely pubescent ; 

 mesonotum faintly shagreened anteriorly, polished otherwise; notauli 

 complete, faintly indicated anteriorly; median lobe broadly rounded 

 posteriorly, touching the scutellum; propodeum sparsely pubescent 

 laterally; abdomen apparently only four jointed, elliptical, the length 

 of the head longer than the head and thorax united, as wide as 

 the thorax, two and one-third times as long as wide; first tergrite 

 twice as wide as long, polished, not striate, the median area longer 

 than wide; second tergite unsculptured, a little longer than wnde; 

 slightly narrowed anteriorly, the sides nearly straight; basal foveae 

 very short, unsculptured; third tergite unsculptured, three times as 

 wide as long, traversed medially by an irregular double row of punc- 

 tures, from each of which projects a short white hair; fourth tergite 

 two-thirds as wide at base as long, triangular, rounded posteriorly; 

 this segment is transversely elevated on basal two-fifths; in front of 

 the elevation the segment is longitudinally striated, behind it is flat- 

 tened, polished, and unsculptured; tergites three and four united as 

 long as the second; wings hyaline, reaching slightly beyond the apex 

 of the abdomen. Shining black; flagellum, middle and posterior 

 femora and tibiae, dark brown; scape, pedicel, and rest of legs, 

 yellow. 



Male. — Length 1.5 mm. Pedicel a little longer than wide, as wide 

 as joint five, as long as joints three and four united; three triangular, 

 as wide as long, longer than four from points of attachment, narrower 

 than the pedicel; four produced tongue-shaped on the lower side of 

 five, one-third as long as five from tip to tip, very short seen from 

 above; five three times as long as wide, longer than the three pre- 

 ceding joints united; emarginate below at base where joint four is 

 closely attached; joints six to seven twice as long as wide; eight and 

 nine less than twice as long as wide; ten as long as seven, subacute 

 apically; abdomen elliptical, a little longer than the head and thorax 

 united, twice as long as wide; tergites three to seven unsculptured, 

 united two-thirds as long as the second; wings hyaline, extending 

 nearly the length of the last five segments past the apex of the abdo- 

 men. Antennae brownish, the scape and pedicel somewhat lighter 

 in color.
