 each other by 1.1 to 1.25 their diameter, separated from eye by 1.0 

 their diameter; face with rather coarse, dense punctures, the punc- 

 tures separated by 0.5 their diameter; vertex less densely punctate 

 than face, the punctures separated by about their diameter; temple 

 finely reticulate, not scabrous; flagellum with 25 to 30 segments; pro- 

 notal trough smooth and highly polished ; mesoscutum and propodeum 

 densely, rather coarsely punctate, the punctures separated by 0.5 

 their diameter or less; propodeum with a shallow medium longi- 

 tudinal furrow; areolet always absent; first tergite about 2.1 as long 

 as wide; first sternite about 0.55 as long as its tergite; second tergite 

 0.94 to 1.35 as long as wide; abdominal segments 2 to 5 with one pair 

 of sternal sclerites, these extending 0.67 to 0.75 the length of their 

 segment; thyridia absent or obscure; first tergite densely, rather 

 coarsely punctate, the punctures separated by less than 0.5 their 

 diameter; second and following tergites gradually less densely punc- 

 tate, the punctures on the sixth tergite separated by twice their

Black. Apical half of clypeus and most of mandible tinged with 

 ferruginous; palpi white; scape and pedicel stramineous in front; 

 flagellum brown basally below, the rest blackish ; stripe on lower edge of 

 pronotum, line on hind corner of pronotum (reaching forward about 

 0.7 the distance to notaulus), tegula, much or most of mesepimeron, 

 and front and middle coxae and trochanters, white; mesoscutum 

 except in front and laterally, scutellum, postscutellum, meso- and 

 metasternum, meso- and metapleurum except mesepimeron and 

 sometimes upper part of mesopleurum, and sometimes more or less of 

 propleurum and of propodeum next to metapleurum, ferruginous; 

 front and middle femora and tibiae white with a light brown stripe 

 above, the tibiae also faintly brownish medially; front tarsus whitish 

 basally, shading to brown apically; middle tarsus brown, white

 extreme apex yellowish fulvous; hind first trochanter brown, whitish 

 below; hind second trochanter white, fuscous basally above; hind 

 femur fulvous, brownish at base and apex, its extreme apex pale 

 fulvous; hind tibia fuscous, whitish at base and stramineous at apex; 

 hind tarsus fuscous, each segment stramineous at base; apex of

This species is very closely related to Poemenia notata Holmgren 

 1859, of Europe. It differs from P. notata in having a more contrasted 

 color pattern, with more fulvous on the thorax and more distinct 

 white and fuscous markings; ocelli slightly larger; and the meso- 

 pleurum and metapleurum more polished and with sharper, closer
