only slightly upcurved, slender, compressed; nodus only gently 
raised, with a minute notch; ventral valve with fine, well spaced 
oblique ridges on tip, tip 0.23 as high at notch as long from notch to 
apex. 
male. Color: differs from female as follows: white spot beneath 
on scape; white markings on head broader; tegula wholly white; 
often most of scutellum and postscutellum white; almost percurrent 
white line on subalarum; 1st gastric tergite with a broad white band 
on apex; 2nd and 3rd tergites with laterally abbreviated white apical 
bands, with that of 3rd tergite comparatively weak or irregular (or 
sometimes all tergites with complete white apical bands); 5th tergite 
red on basal 0.4; 7th tergite black with a broad white apical band; 
clasper brownish with a large black spot; fore and mid tarsi dusky, 
hind tarsus blackish; hind tibia tinged with dusky above, especially 
toward apex; fore and mid coxae with a black area dorsally that is 
bounded anteriorly by a large white area and posteriorly by a 
smaller white area; hind coxa with a large white blotch dorsally on 
basal 0.5 and sometimes with a little brownish staining apically; fore 
and mid trochanters white with a broad and nearly percurrent black 
stripe above; mid trochantellus red as in female but with considera- 
ble blackish above. 
Length of fore wing: 5. 3-7. 3 mm. First flagellomere: 4.4-4. 5 as 
long as deep at apex. Malar space; 0.9 as long as basal width of 
mandible. Temple: 0.5-0. 6 as long as eye in dorsal view. Mesoscu- 
tum: notauli sometimes traceable but faint, sometimes as strong as 
in female. Mesopleuron: speculum often more polished than in 
female, with some smooth interspaces among the punctures. Wing 
venation: ramellus sometimes very short; mediella quite strongly 
arched, its upper part 2.4 as long as the lower part. Propodeum : 
basal face strongly declivous; apical face nearly vertical, well differ- 
entiated from basal face and 0.7 as long as basal face; spiracle 
1.5- 1.7 as long as wide; basal trans-carina sometimes becoming a 
little irregular laterad, but as strongly raised on meson as in female; 
apical trans-carina fine and gently to rather strongly curved forward 
on median 0.3-0. 6 but weak to obsolete laterad; cristae prominent 
robustly cuneate; longitudinal carinae scarcely suggested. First gas- 
tric tergite: postpetiole weakly expanded apicad, 0. 5-0.9 as wide 
apically as long from spiracle to apex; ventro-lateral carina strong 
throughout, except sometimes weaker below spiracle; dorso-lateral
