So far as can be judged from our series, this species is one of the most distinct and 

 least variable. The shape is elegant and characteristic, the prothorax being broad and 

 the body gradually tapering away posteriorly. The coloration appears to be constant, 

 but the violet reflection varies in amount, and is sometimes of different shades in 

 different parts of the body. Male pygidium conspicuously notched, the outline of the 

 notch rounded, the process on either side moderately prominent ; supplementary segment 

 remarkable, with a conspicuous notch with rounded outline and on either side a rounded 

 process covered with long hairs ; posterior margin of last ventral segment slightly 

 emarginate, fringed with short hairs. Female pygidium rather long and narrow at the 

 apex, with sides slightly sinuate and posterior margin slightly rounded, and a con- 

 spicuous apical depression which makes it appear emarginate. The female last ventral 

 segment has not a bisinuate posterior margin as in N. testaceipes. Thirty-two speci-

N. lambiani affinis, sed antennis pedibusque testaceis, fortiter aeneo- sed vix

This species is like N. lainbianus in general appearance, but distinguished from it 

 by the characters given above, and by the secondary sexual characters. The male has 

 the notch in the pygidium very broad and shallow, with no distinct tooth on either side ; 

 supplementary segment very slightly emarginate, bearing long hairs; last ventral 

 segment with its posterior margin slightly emarginate and fringed with short hairs. 

 The female has the pygidium very long and narrowed, apically rounded and without the
