This minute, yellow species is most easily recognized by its long, 

 slender, and glabrous petiole, the propodeum being entirely without 

 lateral teeth, the glabrous outer dorsal surface of the metacoxa, and 

 the metafemur being entirely without an inner tooth. 



Desa^ption. — Yellow, occasionally with vague, indistinct darker 

 stains on dorsum of thorax and abdomen; outer surface of meta- 

 femur with three small, vague spots (fig. 12, n) ; apical tarsal seg- 

 ments always brown. 



Female : 3-3.5 mm. Apex of antennal scape exceeding level of 

 posterior ocelli; ring segment one-third length of segment 4, all 

 flagellar segments approximately equal, stout, covered by white 

 pubescence; scrobe cavity shallow, margined only at ventral one- 

 eighth; frons laterad of scrobe cavity strongly punctate, minutely 

 shagreened ventrad of antennal bases ; malar space one-fourth height 

 of compound eyes ; combined widths of compound eyes slightly greater 

 than width of interocular space at level of antennal bases ; left man- 

 dible with two acute teeth, right mandible with three; frontogenal 

 suture faint or obscured entirely; diameter of f)Osterior ocellus one- 

 half width of interocellar space. 



Pronotum narrow, without an anterior dorsal carina, slight carina 

 at anterolateral angles; mesopraescutum slightly shorter than width 

 at widest point ; dorsum of thorax shallowly punctate, almost glabrous 

 in some specimens, pubescence long and white; posterior margins of
