the outer edge of the labrum, black except for part of the apical 

 half which is dark reddish, palpi slender, nearly typical; thorax 

 with a velvety covering of coarse pale ochreous hairs except on the 

 dorsulum where the posterior half inside the notauli is mostly covered 

 with coarse blackish hairs, dorsulum polished, partly indistinctly 

 reticulated, coarsely punctured, the punctures ranging from con- 

 fluent to one puncture width apart, notauli represented by an im- 

 pressed shining line, mesopleune with pale ochreous hairs, coarsely 

 sculptured somewhat like the metanotum but with larger, more 

 distinct punctures, scutel hairy and sculptured like the anterior 

 third of the dorsulum, metanotum with hairs like on the scutel, 

 but more densely hairy, dullish and with its punctures less dis- 

 tinct and closer together, tegulae blackish except for a polished, 

 brownish stramineous portion, wing base blackish, subcosta blackish, 

 costa blackish stramineous, stigma dark reddish brown with a 

 blackish tinge, rest of veins blackish stramineous but not so dark as 

 the costa, 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 received by the median cell, nearly interstitial and forming 

 an acute angle with the second abscissa of the median vein, legs 

 black and blackish brown, claws mostly pale brown, legs covered 

 with pale ochreous hairs except on the tibise and tarsi where it is 

 darker, rather pale brownish, scopa typical, its hairs pale ochreous 

 except at base above where they are dark brown, mid metatarsi at 

 most apparently as wide as hind metatarsi; propodeum with its 

 enclosure sharply defined especially posteriorly where its truncature 

 is bounded by a carina, finely reticulate and in addition trav- 

 ersed by at least seventeen longitudinal crooked carinas, rest of 

 upper aspect of propodeum appearing to be coarsely reticulate and 

 covered with pale ochreous hairs, pleurae of propodeum with sparse 

 shallow excavations that are finely reticulated and almost hidden 

 by the pale ochreous propodeal floccus; abdomen with its tergum 

 polished, punctured, the punctures clear cut, adjoining on the 

 elevated basal portions of the second, third and fourth tergite-. 

 usually one puncture width or a little more apart on the first tergite 

 and on the depressed portion of the second, third and fourth tergites, 

 second tergite with its elevated portion down the middle : depressed 

 portion :: 10 : 15, fifth tergite with adjoining or nearly adjoining
