This species differs from others having the apex of the scutelkim 

 smooth by having the dorsum of the first tergite distinctly though 

 not strongly sculptured. 



Female. — Length 3.5 mm.; ovipositor 1 mm. Head metallic green; 

 eyes and ocelli usually reddish; mandibles testaceous; scape and 

 pedicel usually dark metallic, scape sometimes testaceous on basal 

 half; flagellum black; thorax mostly dark greenish with median lobe of 

 mesoscutum black; coxae and femora dark greenish; tibiae and tarsi 

 reddish testaceous; abdomen black with a faint greenish tint especially 

 on dorsum of first tergite and on apices of following tergites; wings 

 hyaline with a weakly fuscous spot embracing stigmal vein; tegulae 

 metallic. Vestiture on dorsum of thorax broAvnish, elsewhere 

 apparently paler. 



Eyes conspicuously pilose; ocellocular line barely longer than 

 diameter of lateral ocellus; temples nearly transverse to body axis; 

 malar space equal to about one-fourth of eye height, malar furrow 

 complete; mandibles tridentate, teeth short and subequal; face nearly 

 flat, margin of clypeus very slightly protruding beyond anterior margin 

 of face. Antennae inserted distinctly above lower margins of eyes; 

 first funicular joint obviously a little longer than broad, distinctly 

 thicker than pedicel; second to sixth joints of funicle very slightly 

 longer than broad; seventh subquadrate; club not thicker than 

 funicle and about as long as two preceding joints combined; scape not 

 quite attaining anterior ocellus; scutellum about as broad as long, 

 not overlapping postscutellum, perfectly smooth behind transverse 

 furrow, foveolate groove setting off marginal frenum on scutellum 

 uninterrupted medially; postscutellum with a strong median carina; 

 propodeum distinctly sculptured, with a moderately deep and sharply 

 triangular median depression extending from base nearly to apex 

 and bisected by a longitudinal carina; tooth on posterior femur closer 

 to apex of femur than usual and not so slender as in some other species ; 

 submarginal, marginal, postmarginal, and stigmal veins in approxi- 

 mately the proportions of 30, 17, 9, and 6, respectively; stigmal vein 

 very little thickened and slightly longer than usual; dorsum of first 

 tergite distinctly though not strongly sculptured on its posterior half; 

 second to fifth tergites a little more strongly sculptured dorsally than 

 usual; ovipositor sheaths about two-thirds as long as abdomen. 



Male. — Length 2.75 mm. Similar to the female except in the usual 

 sexual characters. 



The identification of tliis species is based upon two specimens from 

 Germany determined as dentipes by an unidentified entomologist, 

 possibly Arnold Forster. Two other European specimens without 

 locality labels, one of which is said to have parasitized Diprion pini 

 (Linnaeus), are in the collection; also four specimens collected by
