 1894 (female). 



Female. — Length about 6.5 mm. Black, upper orbit dark ferrugi- 

 nous; eye grayish black; wings light fuliginous on apical 0.40, the 

 rest hyaline; coxae and trochanters black; tarsi blackish; femora 

 ferruginous, more or less black basally; tibiae including spurs fer- 

 ruginous. Antenna 28-segmented ; eye bare; ocelli elevated; vertex 

 smooth and polished; frons smooth, polished, with the median por- 

 tion below the anterior ocellus weakly rugulose ; face slightlj'^ less than 

 2.50 times as wide as long, punctate, and with a short median ridge 

 above; clypeus mostly smooth, its basal half slightly elevated, its 

 apical margin truncate and slightly arched; temple wider than eye 

 in dorsal view ; galea about two-thirds as long as the long axis of eye. 

 Median portion of lateral face of pronotum rugose; mesoscutum and 

 scutellum evenly punctate; median lobe of mesoscutum with a shal- 

 low longitudinal depression along each side of the median line ; notaul- 

 ices distinct and finely f oveolate ; mesopleuron finely punctate, upper 

 groove widened posteriorly and coarsely pitted, lower groove foveolate, 

 posterior groove strongly foveate; metapleuron rugose on posterior 

 section, the anterior portion smooth; propodeum rugose, areola de- 

 fined by low carinae, other areas not clearly delimited, pleural carinae 

 very strong. First abscissae of radius and basal vein about equal; 

 third abscissa of cubitus shorter than the fourth ; recurrent vein and 

 second abscissa of cubitus about equal; nervulus postf ureal by 0.67 

 its length; first and second abscissae of submedius about equal; in- 

 teranal vein represented by a short pigmented stump. Second and 

 fifth segments of fore tarsus about equal; apex of hind tibia thick- 

 ened but not expanded into a strongly flaring process; inner spur 

 of middle tibia about half as long as basitarsus, second and fifth 

 tarsal segments about equal; inner spur of hind tibia about half as 

 long as the basitarsus, which is about as long as the next three tarsal 

 segments combined, second tarsal segment longer than the fifth ; hind 

 claws pectinate basally. Second tergite shorter than the third medi- 

 ally : hypopygium very prominent, plowshare-shaped, surpassing last 

 <ergite, about as long as the first five tergites combined, its median 

 ventral line without a longitudinal fold; ovipositor sheath bare, 

 polished, bent downward at apex, its exposed part about 0.80 as long 

 as hypopygium (pi. 5, fig. 20). 



Male. — Essentially similar to the female; antenna 33-segmented.
