the sides ; head and pronotum witli slender black central and 

 lateral lines ; thorax granulated ; tegmina with a raised 

 central carina, marked with yellow at the base before the 

 carina and towards the extremity behind it; costal area of 

 wings pale brown, the nervures interrupted with blackish ; 

 rest of wings brownish hyaline, with yellowish nervures, 

 scarcely interrupted with darker, those towards the base 

 distinctly red. Wings in both sexes considerably broader

Ilah. Tonkin (Tan Moi), June and July [Fruhstorfer) . 



Described from three (one male and two female) specimens. 



The male is very distinct, but the female is very similar to 

 N. sipylus, Westw., except: for the breadth and red basal 

 nervures of the wings. I should not be sqj-prised to find that 

 the wings of N. tonquinensis were more or less flushed with 

 red, at least at the base, in perfectly fresh specimens. It is 

 one of the largest species of the Necrosciinas.
