Brown or brownish testaceous ; pro- and mesothorax above 

 with an interrupted black line on each side. Antennse simple 

 in both sexes, black. Prothorax longer than broad, narrower 

 than the head. Legs blackish fuscous (paler in the $ ), with 

 the base of the tibiae, and the femora beneath, ochreous. Ap- 

 pendices of the $ — app. sup. elongate, acuminate, turned 

 inwards, dull greyish, hairy ; app. inf. long, tAvo-jointed, the 

 basal joint short, the second joint very long, curved strongly 

 inwards, acute, the points crossing ; ventral plate very deeply 

 excised, the sides produced into long, triangular, straight pro- 

 cesses. 



Wings : anterior wings pale smoky fuscous, shining (paler 

 in the ? ), with large, irregular, more or less confluent, whitish 

 blotches in the basal half, and a large, rounded, isolated 

 whitish spot in the disk beyond the middle ; costal veinlets 

 white and margined with whitish, so that the interstice be- 

 tween each veinlet seems to be occupied by an oblong fuscous 

 space ; costa, subcosta, radius, and all the apical neuration, 

 fuscous ; the basal veins and veinlets in the whitish blotches 

 are yellowish ; transverse discal veinlets numerous in the 

 apical half: posterior wings paler than the anterior ; the basal 

 half hyaline with yellowish neuration, the apical half smoky, 

 with fuscous neuration, no basal blotches, but with the isolated 

 round discal spot beyond the middle, as in the anterior. 



Allied to N. grandisj Thbg., of which it might be con- 

 sidered a strongly marked local form, and the Chinese exam- 

 ples of which approach it in coloration ; but that species ap- 

 pears to have short and truncate superior appendices, though 

 with a like-formed ventral plate.
