of head slightly but distinctly emarginate. Head, seen in profile 

 (Fig. 1, A), less abruptly deflexed than in A^. 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 coxse, 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 In the specimen before me the median line is obsolete 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.
