 larger and sparser than on the face; notauli represented by a shining hne; 

 mesopleurae sculptured somewhat like the dorsulum but not so sparsely or 

 distinctly punctured; scutel hairy and sculptured much Hke the dorsulum,

 the metatarsi which are more or less dark brown, legs covered with brownish- 

 golden and ochreous hairs ; scopa typical, its hairs pale golden except at base 

 above where they are dark brownish; hind metatarsi at most apparently a 

 little narrower than mid-metatarsi; propodeum, with its enclosure, distin- 

 guishable from the adjoining region only by its hairlessness, dullish and finely 

 reticulated, rest of upper face of propodeum sculptured somewhat hke the 

 metanotum but not so densely, and covered with finer pale-ochreous hair; 

 propodeal pleurae finely reticulated and with sparse shallow punctures; 

 floccus pale ochreous; abdomen with its tergum shining, faintly greenish, 

 nearly polished, finely reticulate and with sparse, fine, inconspicuous punc- 

 tures from two to six or more puncture-widths apart on the first tergite, the 

 punctures hardly closer on the succeeding tergites; second, third and fourth 

 tergites without an apical, whitish hair-band; apical edge of first, second, 

 third and fourth tergites with a stramineous border; second tergite with its 

 elevated portion down the middle : depressed portion : : 15:8; fifth tergite dullish 

 reticulate, its punctures coarser, more sharply defined and closer together 

 than on the other tergites; pygidium nearly planate, with a sHghtly elevated, 

 triangular embossed area, the end of which is flush with the elevated end of 

 the pygidium; tergum with inconspicuous hairs that are ochreous on the first 

 and second tergites and brownish on the third and fourth tergites except 

 for a fringe of pale hairs at base and apex of the usually exposed parts of the 

 third and fourth tergites ; anal fimbria pale brownish golden ; end of tergite 

 with a dense brush of darker brownish hairs on each side.
