N. brunneus ; thorax vitta interrupta nigra utrinque ornatus. Caput 

 lateribus inermibus. Antennae nigrae, simplices. Alte anticoe pal- 

 lide fuliginosae, maculis magnis plus minusve confluentibus in

Brown or brownish testaceous ; pro- and mesothorax above 

 with an inteiTupted black line on each side. Antennae simple 

 in both sexes, black. Prothorax longer than broad, nan-ower 

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

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

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

 inwards, dull greyish, hairy ; app. inf. long, two-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 nem-ation, 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. grandis^ Thbg., of which it might be con- 

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

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

 pears to have short and truncate superior appendices, though 

 with a like-formed ventral plate.
