of yellowish hairs which are much shorter on the dorsulum where 

 they are darker than the almost whitish hairs on the mesopleurse, 

 dorsulum shining, partly polished, partly finely reticulated, punc- 

 tured like the clypeus but not so sparsely, notauli represented by a 

 shiny line, mesopleurse with almost whitish hairs, sculptured some- 

 what like the dorsulum but more densely reticulated, scutel hairy 

 and mostly polished, otherwise sculptured much like the dorsulum, 

 metanotum hairy and densely sculptured, the sculpture nearly hidden 

 by the hairs, tegulse blackish brown, polished, wing base partly black- 

 ish brown, subcosta blackish brown, stigma pale yellowish 

 stramineous, rest of veins dull brownish stramineous, with a blackish 

 tinge, first recurrent vein received by the second submarginal cell 

 beyond the middle and nearer to the second transverse cubitus than 

 the first transverse cubitus is to the stigma on the radial vein, nervulus 

 nearly interstitial, received by the median cell and forming an acute 

 angle with the second abscissa of the median vein, membrane uni- 

 formly tinged with brown, apical margin darkest, legs blackish except 

 for the small joints of the tarsi which are more or less pale brown, 

 legs covered with brownish golden and nearly whitish hairs, scopa 

 typical, its hairs golden except at base above where they are decidedly 

 darkened, hind metatarsi at most : mid metatarsi :: 11 : 12; propo- 

 deum with its enclosure rather well defined, shiny, finely reticulated 

 and roughened by oblique lateral rugae, rest of upper face of 

 propodeum rugulose, punctured and reticulated, covered with fine 

 nearly whitish hair, propodeal pleurae reticulated, with sparse shallow 

 punctures and almost hidden by the almost white floccus; abdomen 

 with its tergum shining and finely reticulated as well as punctured, 

 the punctures from one to three or more puncture widths apart on

 tergites, first, second, third and fourth tergites with the depressed 

 margin covered with a broad nearly whitish hair band that is not 

 interrupted in the middle, apical edge of first, second, third and fourth

 bands, second tergite with its elevated portion down the middle : 

 depressed portion :: 16 : 12, fifth tergite shining, reticulate, its 

 punctures coarser than on the other tergites, and nearly hidden by 

 the fimbria, pygidium convex, without a shallow furrow on each 

 side, nearly pointed at apex, tergum with inconspicuous blackish
