Apparently very close to N> nivipes, Theobald, differing only 

 in having non-spotted femora and tibiae as far as can be judged 

 from the description appended. 



" $ . Head very dark brown, with white and creamy scales scattered 

 on top, and more thickly toward the front, long tuft in front, a few 

 yellowish scales on the sides, and very dark forked scales with fimbriated 

 tops on the occiput, antennae golden brown, some white scales and some 

 brown at the base with lighter tips, verticels white, pubescence white, 

 first segment basally brown but white at apex ; eyes dark brown or black 

 with very narrow white rim ; palpi golden brown, some scales apparently 

 darker tipped, the last segment white and a narrow white band at apex 

 of each of the three preceding segments, a few white scales at the base ; 

 proboscis brown, not so dark on the head but darker than the antennae> 

 white or yellowish tip. Thorax very dark brown with scattered white 

 flat and yellowish curved scales, no design apparent, — cephalad the white 

 scales are much longer ; scutellum dark brown in the middle and at each 

 end with a lighter spot between, on which are a few white scales ; meta- 

 notum dark brown; pleurae dark brown with white markings; when 

 denuded, thorax has ashy grey reflections with dark brown median and 

 sub-median lines. 



Abdomen dorsally ashy grey, with golden brown hairs, a narrow 

 brown apical band on each segment, much broader on the last two seg- 

 ments so that they are nearly brown instead of grey. 



Legs ; coxae brown, all white tipped, femora dark — i.e. brown scaled 

 dorsally and yellowish on ventral side, tibiae same but a very small apical 

 white spot on fore and mid legs ; first tarsal and two following segments 

 on the fore legs have heavy apical white bands, mid legs have faint light 

 bands in same positions, that on the first tarsal much the heaviest, but 

 still not by any means so broad as on the fore legs ; hind legs dorsally 

 brown, yellowish ventrally much as in the other legs, but the apical half 

 of the second tarsal and all the following segments pure white. Ungues 

 of hind legs light (white), those on mid and fore legs brown. 



Wings cream coloured, spotted with brown, reminding one of A. 

 jamesii, Theob. Two small and four large brown spots on costa, the 

 distal extending back through anterior fork of second long vein, the next, 

 somewhat larger, through first long vein, the third and largest of all 

 extends as a long spot on the costa and sub-costa, and three small ones 

 on the first long vein, so arranged as to resemble an overturned E (fT|)>
