ART. 14 NEW ICHNEUMON-FLTES — CUSHMAN 15 



From that species, however, it differs in its darker elypeus and face, 

 apparently more distinctly areolated and less strongly sculptured 

 propodeum. and entirely impunctate second tergite. 



Female. — Length 3.5 mm; antennae 3 mm. Head largely polished, 

 sparsely hairy, in dorsal view about twice as broad as thick with 

 temples strongly convex; ocell-ocular line a little longer than post- 

 ocellar line, interocellar line and diameter of ocellus equal and dis- 

 tinctly shorter than postocellar line; face slightly narrower than 

 frons, nearly twice as broad as long, finely granularly opaque, medi- 

 ally elevated ; elypeus somewhat less distinctly sculptured than face, 

 more than half as long as broad, apically truncate for nearly the 

 entire breadth; malar space half basal width of mandible; antennae 

 14-jointed, flagellum rather abruptly thickened at sixth joint; basal 

 joint long and slendei'. Thorax almost entirely polished and im- 

 punctate, only the lower anterior margin of pronotunii and upper 

 anterior portion of mesopleurum obscurely punctate ; pronotal scrobe 

 weakly foveolate: notauli impressed anteriorly; propodeum with a 

 very large, well-defined petiolar area and weakh^ outlined apical 

 lateral and combined areola and basal areas, petiolar area trans- 

 versely rugulose, lateral areas obscurely punctate ; alar areolet open ; 

 abdomen petiolate, first tergite granularly roughened, with nearly 

 parallel median carinae and a median groove, postpetiole about twice 

 as broad as petiole, spiracles at about apical third; other tergites 

 polished, unsculptured, second twice as broad at apex as at base, with 

 minute gastrocoeli distant from base; ovipositor not exserted. 



Black; elypeus brownish, mandibles yellow, palpi white; anten- 

 nae fuscous with scape and pedicel yellow in front and thickened part 

 of flagellum reddish ; legs testaceous, front ones paler, all trochanters 

 whitish, hind tibia and tarsus fuscous ; wings hyaline, venation dark ; 

 abdomen black with a median j^eliow herring-bone mark from near 

 base of second tergite to apex and broadening out at the apices of 

 the tergites.

Genus BENJAMINIA Viereck 



Benjaminia Viebeck, Proc. U. S. Nat. Mus., vol. 42, p. 633, 1912. (Genotype, 



Charops fuscipennis Provancher.) 

 ZacJirestoides Viekeck, Can. Ent., vol. 57, p. 177, 1925; vol. 58, p. 2, 1926. 



(Genotype, ZacJirestoides euphydryadis Viereck.) (New synonymy.) 



The two characters by which Viereck distinguished ZacJirestoides 

 from Benjafjiim'a, the length of the postocellar line and the compari- 

 son of the distance between the first tergal spiracles and their dis- 

 tance from the apex of the tergite, are far too trivial for distinguish- 

 ing genera; the latter is variable even within a species.
