Sometiine.s the j)Osterior tij) of the episterua of the metasteruum is browiiisli 

 or blackish, and the middle of the third, fourth and fifth abdominal segments is 

 faintly tawny. In one specimen from Old Calabar the underside of the antennal 

 scape is tawny ; tlie basal silky spot of the elytra almost reaches the scntellum : the 

 three last abdominal segments are slightly buff at the extreme base. 



Differs from N. adorata Thorns., which also has the elytra for the most parr 

 blackish brown, chiefly in the deep and consjiicuous punctuation of the head and 

 prothoi'ax, and in the third and fifth abdominal segments bearing a yellowish spot 

 at each side.

Long. 14i mm., elytr. lUi, lat. 2§. 



The punctuation of the head and prothorax strong and thick, even on the 

 vertex ; the median line of the prothorax and a small space at each side of its 

 base impunctate. The antennae, except the four basal joints, and the whole sutural 

 depression of the elytra clothed with a fine ashy grey and silky pile. The sixth 

 abdominal segment of the male is short, and, like the dorsal part of the fifth, 

 somewhat fnlvous. The fifth segment (ventral part) lias neither a channel nor 

 an impression in both sexes.
