Female. — Length, 19 mm.; antennae, 15 mm.; ovipositor, 15 mm. 

 Face at clypeus and frons about equal in width; face transversely 

 strongly striate with a median carina, but without lateral carinae; 

 frons polished, practically impunctate ; vertex and temples polished, 

 impunctate; postocellar line scarcely longer than ocell-ocular line; 

 interocellar space divided by a deep groove; postocellar furrow dis- 

 tinct; clypeus flat basally, without a transverse ridge; thorax pol- 

 ished, with sparse, weak punctures on mesoscutum, scutellum, and 

 dorsal portions of pronotum and pleura; prescutum strongly angu- 

 lated on each side; mesopleurum with longitudinal impression very 

 weak but with a deep, nearly vertical impression in its dorsal posterior 

 angle ; basal area nearly as long as wide at base, its sides convergent 

 posteriorly ; costulae far before middle of areola ; petiolar area very 

 short, deeply impressed and foveolate medially; subpetiolar area 

 (that portion of propodeum lying below insertion of abdomen) pol- 

 ished, with a few striae; legs slender; subdiscoideus scarcely below 

 middle of postnervulus " ; nervelhis broken distinctly above middle 

 and strongly reclivous; abdomen polished; first tergite two and one- 

 half times as long as wide at apex, apex of sternite much before 

 spiracles ; ovipositor distinctly longer than abdomen. 



Head and thorax yellow; vertex and upper temples more or less 

 ferruginous; ocelli surrounded by narrow brownish areas; scape, 

 pedicel, and first flagellar joint beneath ferruginous, flagellum black, 

 without annulus; sutures of thorax, three longitudinal fascia on 

 mesoscutum, prescutellar fovea, a band surrounding propodeum, nar- 

 row apex of propodeum, and small spot on mesopleurum brownish 

 to blackish; legs testaceous, front and middle coxae and trochanters 

 yellow in front; wings hyaline with black venation and a sharply 

 defined, fuscous spot at apex ; first tergite yellow with median pice- 

 ous fascia reaching nearly to apex; second and third tergites yellow 

 at apex and at anterior angles, piceous in middle, the pattern more 

 obscure on third: other tergites ferruginous, more or less darker in

Type.—C2it. No. 24618^ U.S.N.M. 



Described from two females presented by Mr. William Schaus and 

 collected by Messrs. Schaus and Barnes. 



' I propose this term for the vein normally giving rise to subdiscoideus. In the horis- 

 mology of Rohwer and Gahan it comprises the apical two abscissae of discoideus, and 

 corresponds to the " zweite arealnerv " of Konow. I am proposing the new name instead 

 of using areal vein in order to avoid the confusion that would result due to the fact thai 

 Konow and others have in addition applied the latter term to both nervulus and nervellus. 

 The position of subdiscoideus in relation to it is frequently of much value in classification 

 and the new term is proposed for the convenience of having a definite and comparatively 

 short name.
