palpi nearly typical; thorax covered with an abundance of long 

 slender hairs which are as long on the dorsulum as on the mesopleurse, 

 dorsuluni dullish, finely reticulated, punctured, the punctures mostly 

 from adjoining to three-puncture widths apart, notauli represented 

 by a shining line, mesopleurse sculptured somewhat like the dorsulum 

 but not so closely or distinctly reticulated, scutel nearly polished but 

 hairy and punctured much like the dorsulum, metanotum hairy and 

 sculptured much like the dorsulum except that the sculpture is 

 mostly denser and less distinct, tegulse dark brown, polished, wing 

 base partly blackish brown, subcosta blackish brown, stigma dark 

 brown, rest of veins dull brownish stramineous, or blackish brown, 

 first recurrent vein received by the second submarginal cell far 

 beyond the middle and nearly interstitial with the second transverse 

 cubitus, nervulus received by the median cell, nearly interstitial and 

 forming an acute angle with the first abscissa of the discoidal vein, 

 membrane with a uniform blackish brown tinge, legs blackish except 

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

 legs covered with black or blackish brown hairs, scopa typical, its 

 hairs black or blackish brown throughout, hind metatarsi at most 

 apparently a little wider than mid metatarsi; propodeum with its 

 enclosure poorly defined, dullish and finely reticulated, slightly 

 rugose at base, rest of upper face of propodeum sculptured somewhat 

 like the dorsulum but not so distinctly punctured, and covered with 

 similar hair, propodeal pleurae shining, reticulate, with sparse shallow 

 punctures and almost hidden by the brownish and blackish floccus; 

 abdomen with its tergum shining and sculptured much like the 

 propodeal pleurae but with apparently more distinct and smaller 

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