Original description. — Alis anticis atris, fascia obliqua pone 

 medium, in medio contracta, dorsum versus latiore, lutescenti-argentea. 

 Exp. al. 2J-2^ lin. Head . and face reddish-yellow ; palpi whitish; 

 antenna fuscous, basal joint white. Anterior wings deep black ; a 

 little beyond the middle is a yellowish-silvery fascia, rather obliquely 

 placed, often attenuated in the middle, and the inner edge of the 

 lower half expanding more or less towards the base ; cilia of the hind 

 margin whitish. Posterior wings grey, with grey cilia (Stainton, 

 Entom. Annual, 1857, p. 112). 



Imago. — Head ferruginous. Anterior wings 5-6 mm. in expanse ; 

 black in colour ; a silvery slightly oblique transverse fascia, slightly 

 attenuated in the centre, broadest on the inner margin, its inner edge 

 slightly concave and outer edge straight, placed just beyond the 

 middle of the wing ; cilia blackish, with the tips distinctly whitish. 

 Posterior wings and cilia grey. 



Comparison of N. atricollis with N. angulifasciella, N. 

 arcuatella, N. rubivora, etc. — From N. angulifasciella and N. rubi- 

 vora, N. atricollis may be distinguished by the rusty yellow frontal 

 tuft ; from N. arcuatella the purer white tips of the cilia, and the 

 distinct cilial line, as also the darker hind tarsi, serve to distinguish 

 it (Heinemann). X. atricollis belongs to that section of the genus in 

 which the black anterior wings have a bright silvery fascia. The 

 only known species with which it can be confounded are N. anguli- 

 fasciella and A 7 , arcuata. From the former it may be distinguished by 

 its smaller size, by the narrower anterior wings, and by the silvery 

 fascia being less curved. From N. arcuata it is by no means easily 

 distinguished. Both are of the same size, and the colour of the fascia
