Male: Unknown. 



Female: Front wing about 8.0 mm. long; first flagellar segment 

 about 1.7 as long as second; bead about 1.03 as wide across temples 

 as across eyes; punctures on temple very small, separated by about 

 4.0 tbeir diameter; tborax about 2.70 as long as nigh; pronotum with 

 rather dense, crowded, moderately coarse punctures, these partially 

 obscured by weak wrinkling in most areas, almost completely obscured 

 by strong, but small irregular wrinkling in trough of pronotum; 

 punctures of mesoscutum small, separated by about 1.3 their diameter, 

 the lateral lobe of mesoscutum with a median longitudinal bare area; 

 mesepimeron with moderately dense hairs over its entire surface; 

 metapleurum with rather dense, medium-sized punctures intermingled 

 with wrinkles that partially obscure the punctures; petiolar area 

 about 0.31 as long as combined areola and basal area; propodeal 

 teeth about 0.5 as long as their basal width; first lateral area with 

 dense hairs all over; hind femur about 2.18 as long as deep, with very 

 small, weak, adjacent punctures all over and short, dense hairs; 

 second segment of middle tarsus about 1.45 as long as deep; fifth

 dense; ovipositor sheath about 1.25 as long as front wing. 



Blackish. Mandible, flagellum, and abdomen with ferruginous 

 tinges; palpi and tegula brown; legs entirely fulvous; wings hyaline. 



This species can be recognized by its dense coarse punctures and 

 rugulosity on the pronotum and metapleurum. It has been con-
