 off at apex, rest of upper face sculptured somewhat like the mesopleurae but 

 with smaller pits and covered with concolorous hair; propodeal pleurae finely 

 reticulate, sparsely indistinctly punctured, propodeal fioccus whitish; abdo- 

 men with its tergum shining, almost polished, partly finely reticulated, dis- 

 tinctly punctured, the punctures mostly three or four puncture-widths apart; 

 first tergite with erect whitish hairs, second and third tergites with shorter, 

 reclinate, whitish hairs; second tergite with its elevated portion down the 

 middle : depressed portion presumably :: 21 : 6; third and fourth tergites 

 with whitish reclinate hairs on the elevated portion; exposed portion of sixth 

 and seventh tergites with a stramineous margin; seventh and eighth sternites 

 as in the figures of these parts; tergum not conspicuously banded, appearing 

 bandless, with rather inconspicuous hairs that are supplemented on the sides 

 of the second, third and fourth tergites by thin ochreous hair; hair at apex 

 of abdomen whitish or pale ochreous; cardo finely reticulated; hypopygium 

 mostly dark brownish; lingam and end of stipes pale stramineous.

 almost white hairs; head with its facial line : transf acial line :: 52 : 64; axial 

 line : temporal line :: 26 : 15; elevated portion of malar space shorter than, 

 depressed portion; malar line : joint 3 of antennae :: 2 : 8; ocelloccipital line : 

 greatest diameter of lateral ocellus :: 4 : 4; head covered with whitish hairs, 

 front rather longitudinally sculptured, almost reticulate, not elevated into 

 a welt along the fovea; fovea at most : ocellocular line :: 7 : 12; distance 

 between fovea and ocelli : ocellocular line :: 5 : 12; foveal band poorly devel- 

 oped, not present at upper end of the inner eye-margin; fovea attenuated 

 toward its lower end which is apparently a little below the clypeal line, fovea 

 filled with pale-ochreous hairs; face mostly shiny, partly finely reticulate, 

 with rather indefinite punctures that are apparently well separated; clypeus 

 convex, sculptured like the face except that the punctures are larger and well 

 defined; clypearea represented by sparser puncturation down the middle of 

 the clypeus, the latter thinly hairy, its sculpture not at all hidden by hairs; 

 labrarea truncate, its width at base : length down the middle :: 10 : 3; width 

 at apex : length down the middle : : 5 : 3 ; labrum with a fringe of golden hairs 

 and with a poorly developed median longitudinal elevated line between the 

 labrarea and apical edge of labrum; joint 3 of antennae : 4+5 :: 8 : 9; joints 

 4 and 5 thicker than long, the succeeding joints as thick as long or little 

 longer than thick except joint 12 which is distinctly longer than thick; antennae 

 blackish throughout; mandibles atypical, robust, extending to the outer 

 edge of the labrarea, black except for the apical fourth and inner edge which 

 are clear dark reddish; palpi nearly typical; thorax covered with an abundance 

 of pale-ochreous, almost white hairs which are shorter on the dorsulum than 

 on the mesopleurae; dorsulum dullish, finely reticulated and punctured like 

 the face but more distinctly so and not so shiny; notauli represented by a 

 shining line; mesopleurae with almost whitish hairs, sculptured somewhat 

 like the dorsulum but not so closely or distinctly punctured; scutel hairy 

 and sculptured much like the dorsulum, except that its disc is more shiny;
