Female. — Length, about 2 mm. Black, polished; the antennal 

 scape, pedicel, palpi, mandibles, legs including all coxae, and the first 

 abdominal segment testaceous; wing veins and stigma dark brown, 

 the second cubital cross vein pale. Antennae 23-jointed in the type;

 about two-thirds the length of the second flagellar joint, slightly 

 shorter than the third, about equal to the fourth, and a trifle longer 

 than the fifth; head about twice as wide as long antero-posteriorly, 

 occiput concave and polished; frons and vertex polished, the latter 

 without a median groove or with only a trace of one between the
