with a broad, weak, rounded median tooth that is a little accentuated 

 by impressions on each side of it; temple narrow, wealdy convex; ty- 

 loids linear, sharp, extending about 5 segments; mesoscutum strongly 

 mat, with medium-sized, weak punctures that are separated by 

 about 1.3 their diameter; mesopleurum polished, with coarse, close 

 pimctures and close reticulate wrinkling that in most areas replaces 

 the punctures; second tergite of male strongly mat on its basal 0.7 ±, 

 the rest less strongly mat, its punctures rather large, weak, separated 

 by about 0.6 their diameter; second tergite of female weakly mat, its 

 apical 0.3 db subpolished, on its basal 0.7 ± with medium-sized weak 

 punctures that are separated by about 2.5 their diameter, elsewhere 

 almost impunctate; ovipositor sheath about 0.47 as long as front wing; 

 ovipositor moderately compressed, its tip as in figure 327,k.

 whitish to dark brown; labial palpus of male dark brown; both palpi 

 of female dusky brown; flageUum of female brown basally, usually 

 with a median short white stripe above, extending about 4 segments; 

 tegula fulvous, ferruginous, or brown; front and middle legs ferrugi- 

 nous, their tarsi usually dusky apically, especially the middle tarsus; 

 hind coxa, trochanters, and femur ferruginous, the apical 0.12 ± of 

 the femur fuscous; hind tibia dusky ferruginous, its apical 0.15± 

 infuscate; hind tarsus of male dusky brown, paler at the incisures, the 

 third segment and basal half of fourth often white; hind tarsus of fe-
