of head slightly but distinctly emarginate. Head, seen in profile 
(Fig. 1, A), less abruptly deflexed than in N. undata (Fig. 1, B), 
and the apex less acute. Ratio of lengths of antennal segments 
19:23:20:35:45 (in undata the ratio of segment II to segment III

is 23:17); the three basal segments yellowish, the third darkened 
toward the apex and on the sides, fourth and fifth segments 
black. Rostrum nearly reaching the hind coxae, apical segment 
piceous. 
Pronotum black and closely punctate on the anterior half, 
obscure testaceous and more sparsely punctate on the posterior 
half ; median line and a small irregular spot behind each callosity 
yellow. In the specimen before me the median line is obsolete 
behind the middle of the disc. Lateral margins straight, white, 
impunctate, broader than in N. undata ; when viewed from 
above, there appears to be a narrow black line along the extreme 
edge, but this is not visible when the pronotum is viewed from 
the side. Anterior and humeral angles as in N. undata ; postero- 
lateral margins a little more oblique and the posterior angles less 
broadly rounded than in that species.
