This species is more variegated than N. luguhris, but 

 the colours ai-e greatly confused together. The head is 

 punctured: the prothorax is subhexagonal, with a deep 

 longitudinal central depression, the surface of which is 

 marked with numerous very fine curved and longitudinal 

 striga3 ; there is a small tubercle on each side, about one- 

 third of the distance from the anterior angle. The lateral 

 angles are sharp and the posterior angles are prominent, 

 produced backwards and slightly elevated, leaving a 

 depression within the posterior angles. The posterior 

 margin is emarginate on each side, and rounded and 

 entire in front of the scutellum. The disc is black and the 

 sides ferruginous, varied with luteous villosity. The elytra 

 have the shoulders very prominent, rounded, elevated, 

 and fulvous, with a deep round impression within the 

 humeral angle, terminated within by the curved and raised 

 carina, which extends nearly to the apex of the elytra, ter- 

 minating in the ordinary subapical tubercle ; the sutural 

 space between the carina is deeply impressed, with its sides 

 gradually elevated and marked with cicatricose punctures ; 

 towards the subhumeral impression it is black, followed 

 by a luteous, transverse, villose fascia ; towards its extremity 

 it is darker, but varied Avith ferruginous and black. The 

 apical tubercle of each elytron is conical and fulvous, with 

 a small point on the outside of each. There is also a 

 raised lateral tubercle on each elytron beyond the middle, 

 outside of the carina. The lateral margins of the abdo- 

 minal segments are exposed and rounded, the two ordinary 

 spiracular tubercles conical, and the podex emarginate at 

 its extremity and Avhite in the middle. The legs are 

 fulvous varied with black, the tibia3 having a black central 

 fascia, and the tarsi are fulvous with the joints black at the 

 ends. The middle of the ventral surface of the abdomen 

 is clothed with white pile, through which a few oblong 

 cicatricose punctures are visible.
