by distinct ridges ; pleurae with an area on each side of femoral 

 furrow rugulose. Femoral furrow densely punctate, the posterior 

 sclerit becoming transversely striolate above. Mesosternum with 

 the grooves finely striolate, with a small median anterior íbvea 

 behind which there is a sharp median carina, triangular when seen 

 in profile. Between the posterior margin of the grooves and the 

 middle coxae there is a triangular concave area finely rugulose and 

 provided with a low but distinct longitudinal carina; posterior la- 

 teral teeth distinct. Posterior margin of grooves separated from mid- 

 dle coxae bv less than length of the latter. 



Antennae with the scape and underside ot pedicel yellowish ; 

 basal dorsal portion of pedicel black ; flagellum yellowish, frequent- 

 ly with a testaceous tinge ; ring-joint yell ow. AU coxae black ; an- 

 terior and middle femora, and ali tibia orange-yellow ; knees, tip 

 of tibiae and tarsi nearly white ; posterior femora black, base and 

 tip yellowish or whitish. Anterior face of front coxae provided with 

 a very distinct oblique groove bounded on the outer side by a 

 very pronounced ridge. When seen in profile this ridge looks like 

 a tooth. Posterior coxae finely reticulate. Wings hyaline. 



Abdómen black, sometimes more or less brownish at base be- 

 neath, strongly arched above ; as seen from side height equals 

 about three fourths of length. Posterior margin of each segment 

 smooth, polished : rest of abdómen with a fine pavement-like sculp- 

 ture. 



Male. — Length, 2 to 2.25 mm.; abdómen, .9 to I mm. Simi- 

 lar to female in color and sculpture. Antennae brownish, especially 

 above and at tip of scape ; funicle joints strongly arched above, 

 pedicellate at apex, the constricted portion about one fourth the 

 length of the joint ; club shorter than scape, hairs nearly white, a 

 little longer than the diameter of joints, arranged in two whorls. 

 Five funicle joints present. Propodeum similar to that in female, 

 the furrow narrower behind than in front; in one specimen a me- 

 dian carina present in front. Petiole longer than hind coxae, very 

 delicately reticulate above. Abdómen black with only a trace of 

 brownish at base below ; the second and third segments form the 

 cephalic aspect, the fifth about three fourths the length of the 

 fourth.
