Hab. Pulo Penang. In Mus. D. Westermanni Havnise. 



This species is closely allied to N. Marmessus, but differs 

 in its colours and in the clavate anal styles. It is very 

 slender and cylindrical, greenish brown and opake. The 

 head wide, with very prominent eyes ; ocelli obsolete. 

 The antennae are longer than the body, very slender, dark 

 brown, with four white rings placed at equal distances 

 apart, the last being close to the tip. The pro- and meso- 

 thorax are simple. The tegmina are small, subovate, red- 

 dish brown ; the carina black, acutely, but not strongly, 

 angulated before the middle ; the outer margin white. 

 The wings large, brown, with scarcely distinct paler trans- 

 verse clouds between the longitudinal veins ; the latter are 

 rather darker reddish brown ; the costal area is reddish 

 brown, scarcely darker than the hind part of the wing; 

 the median vein simple and pale green ; the fore margin at 

 the base is reddish brown. The abdomen is blackish 

 brown and slender ; the terminal segments short, and but 

 slightly swollen, the last with its lateral posterior angles 

 produced ; the anal styles porrected, incurved, and gra- 

 dually clavate to the tips ; the three terminal ventral seg- 

 ments are constricted at the base of each, the last extend- 

 ing to the end of the last dorsal segment. The legs are 

 long, very slender, and simple, and of luteo-fulvous colour.

Hab. In Borneo (Sarawak) (D. Wallace). In Mus. 

 W. W. Saunders. 



This very slender species is well distinguished by its iri- 

 descent wings, and the white granules on the pro- and 

 mesothorax. The head is rather broad, unarmed ; eyes 

 large ; front of head dirty whitish, with the upper lip 

 tinged with green. The antennae are very long and slender, 

 dark brown, with three distant white annuli. The meso- 

 thorax is slender and nearly cylindrical ; the under surface 

 and sides pale greenish buff; the disc, like that of the pro- 

 thorax, dark brown, with a fine raised longitudinal median 

 line, the surface covered with numerous minute whitish 

 granules. The tegmina are very small, nearly round ; the 

 middle of the central carina very strongly elevated and 

 rounded, brown ; the costa tinged with green and pink, 

 and the disc marked with a transverse whitish line. The 

 wings are brown, very transparent, and strongly iridescent ; 

 the costal area pale brown, strongly tinged with pink, and 

 with a pale whitish line extending from the base to about 

 the middle, where it is gradually lost. The fore legs are 

 wanting ; the four hind legs are long, very slender, and 

 simple, brown ; the tips of the femora and the tarsi pale 

 buff. The abdomen is long and slender, brown, paler be- 

 neath, and tinged with green ; the three terminal segments 

 dilated ; the ninth strongly emarginate at its extremity, 

 with the obtuse anal styles porrected, curved, and setose ; 

 the terminal ventral segments are much swollen, the last 

 not extending to the extremity of the eighth dorsal seg- 

 ment.

 antennis valde elongatis, fuscis, albido 6-annulatis ; tegmi- 

 nibus parvis, ovalibus, postice subtruncatis, tuberculo conico 

 nigro instructis ; alis fuscis, area costali luteo-fusca ; pedi-
