This species ditfers from N. regina sp. nov. in the smaller size, in the the black 

 colour of the antenual scape, in the third and fourth abdominal segments bearing an

 and in the longer scutelhun.

Long. IT mm., elytr. 12, lat. :i. 



Head ochreous, rather strongly concave between the antennae. First joint 

 of the latter rufous ochreous, its upperside more or less blackish brown ; second 

 and four or live succeeding joints black, the remainder tawny. Protliorax ii 

 little longer than broad, with a s])arse and somewhat crowded punctuation, the 

 punctures dense and very coarse at the base. Elytra densely punctured, with 

 the jiunctures ii-regular at the base near the shoulder ; the apices broadly and 

 somewhat obliquely emarginate, with both angles produced into a short jiointed 

 tooth ; the sutural depression rather deej) anteriorly, bordered with a slight 

 keel, which is more distinct in Iront of the middle. Prosterumn ochreous 

 anteriorly and in the middle, with the ochreous region somewhat extended up 

 to the disc at the front margin ; mesosternum Idaek. tinged with tawny. Two 

 basal segments of the abdomen silky wJiite, faintly tinged with olive ; third, fourth 

 and tifth segments black witli a, fint ol' brown, middle of the lilth rnfous ; 

 the latter with a longitudinal channel. deej)est in the middle, with the apical 

 margin somewhat recurved and broadly emarginate — and with the apical jiart of the 

 lateral margin l)ent above ; dorsal pai't of the fifth segment strongly convex, and 

 rufous near the ajiex, with the apical margin somewhat flattened and emarginate, 

 and narrower than the ventral part. Femora and coxae of the four anterior legs 

 ochreous, with the tarsi more or less tawny. Posterior femora just reaching the 

 apex of the second abdominal segment.
