This form diifers from N. atra sp. nov., to which it is closely allied, in tiie longer

 the prothorax and two basal segments of the abdomen.

Tlie suture is clothed with an asliy silky pili' imniedialeiy Ix^iiind tlie scniellum, 

 as in A. /VwitoKs sp. nov. Smaller Hian the ]iriMH-ding spec'ies, with Ihr iintennao 

 (exce[)1 the scape) of a black colour as in A. eiiKtrijiiidta, tJlievr. From the latter 

 it is distinguished by Ihe scajie of antennae being ferruginous undei-ueath, by the 

 prouotuiu with the anterior fourth (not half) ochreous, by tlie suture l)earing an 

 asliy silky ])ubescence behind the scutelhuu, by tl\e upperside of the abdomen 

 (except the jjygidium which is somewhat pitchy) and thc^ venti-al parts of tlie third 

 and fonrtii segments being entirely black.
