Front wing of male 5.8 to 8.5 mm. long, of female 7.5 to 8.5 mm. 

 long; face rather narrow, its median 0.2 a little raised and with small 

 punctm-es that are separated by about 1.8 their diameter; cheek 

 unusually long, about 0.83 as long as basal width of mandible in male, 

 about 1.2 as long as basal width of mandible in female; mesopleurum 

 subpolished, with rather coarse strong punctures, these denser in 

 female than in male, mesopleurum also with a little weak wrinlding, 

 that below the subtegular ridge irregular, not longitudinal; propodeal 

 crests exceptionally short and high; apical carina of propodeum in 

 male often traceable across the middle of propodeum; intercubiti 

 subparallel or faintly convergent anteriorly; second tergite strongly 

 mat, in male with medium-sized shallow punctures that are separated 

 by about 0.7 their diameter, in female with moderate-sized punctures 

 that are separated by about 2.5 their diameter; ovipositor tip as in 

 figure 327,a. 



Male : Head black. Face white with a pair of complete or incom- 

 plete black or brown stripes extending from antennal sockets to clypeal 

 foveae, then around base of mandible; cheek, frontal orbit, lower 

 part of temple, clypeus, mouth parts, and front of scape, white. 

 Pro thorax black; usually area on propleurum next to the coxa, collar, 

 broad lower margin of pronotum, hind corner of pronotum, and 

 usually the broad upper margin of pronotum, white. Mesothorax 

 black; tegula, subtegular ridge, often a spot in center of mesoscutum, 

 scutellum, and postscutellum, white; irregular area on mesopleurum, 

 more or less of mesepimeron, and often part of mesosternum a mixture 

 of whitish and fulvous. Metapleurum fulvous with its front and 

 lower margins more or less black, or sometimes black with a median 

 fulvous area; upper division of metapleurum mostly yellowish white; 

 propodeum fulvous, mostly yellowish white below its apical carina; 

 front and middle legs fulvous, their trochanters largely, and all but the 

 apical parts of their tarsi pale yellowish; hind coxa, trochanter, and 

 femur fulvous, the apical 0.1 ± of femur usually a little infuscate; 

 hind tibia fulvous, its basal 0.18 ± paler and its apical 0.35 ± infuscate, 

 its extreme apex often fulvous; hind tarsus white, the tip of its last 

 segment fulvous; abdomen fulvous, the basal 0.6 ± and apical 0.1 ± 

 of its first segment yellowish fulvous, its seventh tergite without a 

 white spot but sometimes with a yellowish fulvous area. 



Female : Black. Usually a small stripe on frontal orbit, a stripe 

 on upper side of flagellum that covers about 6 segments, collar, tegula, 

 subtegular ridge, usually the postscutellum and a spot on scutellum, 

 small apical area on sixth tergite, and large spot on seventh tergite,
