MICROTORIDEA, ne>Ar genus. 



Presumably related to Microtorus Foerster, from which it may be 

 separated by the 10 pemiltimate joints of the flagel being longer than 

 wide and by the marginal cell being longer than the stigma. 



Type. — Microtoridea lissonota, new species. 



MICROTORIDEA LISSONOTA, new species. 



Female. — Length, 3 mm. Head black; face including clypeus dis- 

 tinctly pubescent, punctured, malar space smooth and polished, sepa- 

 rated from the face by a fuiTow, rest of head polished; hind ocelli 

 with a furrow between them, nearer the eye margin than to each 

 other and apparently a little nearer to each other than to the occipital 

 carina ; malar line apparently a little longer than mandibles are wide 

 at base ; basal half of mandibles mostly yellowish, apical half mostly 

 brownish; palpi pale; scape stramineous, pedicel and flagel more or 

 less brownish, flagel 19-jointed; thorax black; pronotum with its 

 transverse furrow almost crowded out in the middle by a rather broad 

 process apparently extending back from the anterior edge ; tubercles 

 yellowish, propleurse mostly polished; mesonotum polished, virtually 

 bare, with distinct, converguig notauli that extend nearly three- 

 fourths the distance from the anterior edge and are nearly tlu-ee times 

 as far apart anteriorly as posteriorly; upper anterior comer of meso- 

 pleurse, tegulse, and wing base yellowish; mesopleurae partly sculp- 

 tureless, partly punctured, completely separated from the meso- 

 sternum by the sinuous sternauli; veins brownish, stigma stramineous; 

 legs almost entirely stramineous, apical joint of tarsi and claws 

 brownish; propodeum with its basal area almost crowded out, trans- 

 versely linear, the enternal area and spiracularea confluent, the areola 

 hexagonal, wider anteriorly than posteriorly, its anterior edge straight, 

 its posterior edge arched, the costula joining before the middle, areola 

 between the costidse nearly three times as wide as long down the 

 middle, area dentipara and second pleural area separated, petiolarea 

 nearly tliree-fourths the length of the propodeum, concave and at 

 most two-tliirds as wide as long down the middle, third lateral and 

 angular areas confluent; abdomen polished, inconspicuously pubes- 

 cent, first segment black with a poorly defined dorsal carina on each 

 side that extends a little beyond the spiracles but not near them, 

 petiole depressed, apparently twice as broad at base as tliick dorso- 

 yentrally; postpetiole parallel sided, approximately twice as wide at 

 apex as long, the spiracles at the anterior lateral angles; membranous 

 portion of first segment and all of second segment mostly stra- 

 mineous, following segments more or less testaceous; ovipositor 

 approximately as long as the abdomen less the first segment.
