Male and female. Dark cinereous. Abdomen and hind wings 

 paler. Palpi erect, rising much higher than the vertex ; third joint 

 lanceolate, nearly half the length of the second. Fore wings nar-

 pale cinereous, undulating ; marginal line blackish, interrupted by 

 the veins. Length of the body 5— 5^- lines; of the wings 13—14 

 lines. 



The length of the third joint of the palpi is the only character 

 which seems to distinguish this species from N. mcestella.
