less between the labrarea and apical edge of labium, joint 3 of 

 antenna' : 4 + 5 :: 9 : 8, joint 4 thicker than long, the succeeding 

 joints as thick as Ions or a little longer than thick excepl joint 12 

 which is distinctly longer than thick, antenna' blackish throughout, 

 mandibles typical, extending to the outer edge of the labrarea, black 

 except for the apical half which is mostly dark reddish, palpi nearly 

 typical; thorax covered with an abundance of pale ochreous almost 

 white haiis which are as long on the dorsulum, where they are thinly 

 mixed with black hairs, as on the mesopleurae, dorsulum dullish, 

 finely reticulated and punctured much like the face, notauli repre- 

 sented by a shining line, mesopleurae with almost whitish hairs 

 except along the upper margin where there is an admixture of black 

 hairs, sculptured somewhat like the dorsulum but more closely and 

 less distinctly punctured, scutel hairy and sculptured much like the 

 dorsulum except that most of its hairs are black, and the anterior 

 margin is nearly polished, metanotum hairy and sculptured like the 

 dorsulum except that the sculpture is denser and less distinct and 

 the hairs are all whitish, tegular dark brown, partly nearly polished, 

 wins base partly blackish browm, subcosta blackish brown, stigma 

 dark brown, its low r er margin blackish, rest of veins dull stramineous,

 abdomen with its tergum shining, nearly polished, feebly reticulate 

 and finely,- sparsely punctured, the punctures mostly from four to 

 six puncture widths apart on the first tergite, the punctures hardly 

 closer on the succeeding tergites, second, third and fourth tergites
