 ( misidentification ) . 



This species is most readily recognized in the female by the minute 

 mesotibial spur, the short rugose petiole, and the exserted hypopygium 

 with the apex not isolated from the eighth tergite (as in fig. 13, /) ; the 

 male is recognized at once by the basally enlarged antennal scape 

 (%8,/). ^ 



Description. — Entirely black, or occasionally dark rufous; base 

 of metafemora occasionally tinged with brown. 



Female: 5-5.5 mm. Antennae inserted slightly ventrad of center 

 of frons, scape exceeding by one-fifth its length level of posterior 

 ocelli; width of malar space slightly more than one-half height of 

 compound eye; frontogenal suture almost obliterated, occasionally 

 traceable near ventral margin of compound eye, a secondary carina 

 usually extends from base of mandible to genal area posterior to 

 compound eye; left mandible with one large, acute dorsal tooth and 

 one small ventral tooth, right mandible with three equal, acute teeth. 



Prepectus narrow, bladelike, slightly broader anteriorly, apex not 

 quite reaching tegula ; mesotibial spur minute ; outer surface of meta- 

 femur densely covered with short pubescence, outer ventral margin 

 with nine to twelve minute teeth, basal one slightly larger than fol- 

 lowing teeth; inner tooth wanting; apex of metatibia slender, acute; 

 apex of posterior tarsus provided with four to six long setae, claw 

 small, basal enlargement with three minute teeth. 



Propodeum completely covered with small reticulations, these 

 rugosities slightly stronger near apex, spiracular openings vertical, 

 slightly constricted in middle; petiole short, less than twice as long 

 as wide, surface provided with coarse, confused carinae, distinct 

 lateral carinae present at base, but usually becoming obsolete before 

 reaching apex; gaster usually slightly longer than metafemur; cerci 

 oval, situated near posterior margin of epipygimn ; apex of ovipositor 

 sheath produced in a long, acute point, a sparse tuft of setae present ;
