This plain-looking species is nearly allied to N. Sipylus, 

 but has the mesothorax longer, the median vein of the costal 

 area of the wings furcate, the base of this part sanguineous, 

 the legs and antennae much shorter, the abdomen longer, 

 with the anal styles shorter. The head is rather longer 

 than wide, moderately convex ; the hind part divided by 

 several slight longitudinal impressions. The antennae very 

 slender, about 25-jointed, each joint (beyond the tenth) 

 formed of about five or six minute articulations, the last 

 being rather thicker than the rest and darker coloured. 

 The pro- and mesothorax are finely granulated ; the latter 

 is considerably elongated. The tegmina are small and 

 ovate ; the central carina moderately elevated before the 

 middle. The wings are large, smoky-coloured, with darker 

 veins; the costal area darker, obscure brown, slightly cloud- 

 ed, with the base dark flesh-coloured, the main vein furcate 

 at a considerable distance from the base. The abdomen is 

 long and cylindrical ; the terminal segments short and 

 conical ; the anal styles short, obtuse, and porrected ; the 

 oviduct small, and extending to about half the length of 

 the ninth dorsal segment.

This species is closely allied to N. Phcetusa, but is well 

 distinguished by its short 3-ocellated head, its unicolorous 



antennae, the proportions of its prothorax and unarmed me- 

 sothorax, shorter tegmina, reticulated wings, with the me- 

 dian vein of the costal area furcate, differently constructed 

 terminal segments of the abdomen, and fasciated legs. The 

 head is flattened above, with the three small ocelli distinct ; 

 the eyes very prominent. The antenna? very long and 

 slender, uniformly brown. The prothorax is of the usual 

 length. The mesothorax slender and simple, widened be- 

 hind. The tegmina short, subquadrate, obliquely trun- 

 cate, with the median carina formed into a strong conical 

 elevation in the middle. The wings are long and narrow, 

 pale brown, the middle marked with numerous hyaline 

 waves ; near the tip is a rather indistinct transverse paler 

 cloud ; the costal area itself is but slightly darker than the 

 rest of the wing, and unspotted ; its median vein is furcate 

 before the middle of its length, the two branches uniting 

 together before the tip, and the united vein again joining 

 the next vein still nearer to the tip of the wings. The ab- 

 domen is long and slender ; the last joint alone pale fulvous 

 buff; this joint is truncate at its extremity, the sides being 

 strongly deflexed, the deflexed angles armed within with 

 short teeth ; the eighth dorsal segment is nearly twice 

 as long as the seventh ; the three terminal ventral seg- 

 ments are very short, scarcely reaching beyond the base 

 of the eighth dorsal segment. The legs are long and 

 slender, with the tarsi luteous ; the fore legs are dark 

 brown, the four hind ones black at the tips of the femora ; 

 the tibia are also black, with two or three broad luteous 

 rings.
