thinly hairy, its sculpture not at all hidden by hairs, labrarea tri- 

 angular, its width at base : length down the middle :: 12 : 5, labrarea 

 at base nearly two-thirds as wide as the labrum, the latter with 

 a fringe of brownish hairs, labrum apparently structureless and 

 sculptureless between the labrarea and apical edge of labrum, joint 

 3 of antennae : 4 + 5 :: 9 : 6, joints 4 to 9 thicker than long, the 

 succeeding joints as thick as long or a little longer than thick except 

 joint 12 which is distinctly longer than thick, antennae blackish 

 throughout, mandibles typical, robust, extending a little beyond the 

 outer edge of the labrarea, black except for the apical half which is 

 dark reddish, palpi nearly typical; thorax covered with an abundance 

 of whitish hairs which are distinctly shorter on the dorsulum where 

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

 dorsulum dullish, finely reticulated, indistinctly punctured, the 

 punctures mostly many puncture widths apart, notauli represented 

 by a shining line, mesopleurse with almost white hairs, sculptured 

 somewhat like the dorsulum but more shining and more distinctly 

 punctured, scutel hairy and sculptured much like the dorsulum, 

 metanotum hairy and sculptured like the dorsulum except that the 

 sculpture is denser and less distinct, tegulse blackish brown, polished, 

 wing base partly blackish brown, subcosta blackish brown, stigma 

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

 blackish tinge excepting the cubiti which are yellowish, received by 

 the second submarginal cell beyond the middle and nearly as near to 

 the second transverse cubitus as the first transverse cubitus is to the 

 stigma on the radial vein, nervulus interstitial and forming an acute 

 angle with the first abscissa of the discoidal vein, membrane uniformly 

 tinged with yellowish brown, legs dark brown, covered with brownish 

 golden and pale ochreous or whitish hairs, scopa typical, its hairs of 

 the lower half pale ochreous almost white, of its upper half with a 

 golden hue, hairs at base above decidedly darkened, hind metatarsi 

 at most apparently a little narrower than mid metatarsi; propodcum 

 with its enclosure poorly defined, shining and finely reticulated, rest 

 of upper face of propodeum sculptured somewhat like the mesopleurse 

 but with smaller punctures, and covered with finer pale ochreous 

 hair, propodeal pleurse fine reticulated, shining and with sparse 

 shallow punctures and almost hidden by the nearly white floccus; 

 abdomen with its tergum shining, satiny, finely reticulate and indis- 

 tinctly punctured, the punctures 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 with an apical,
