N. scarra Schs. also has whitish-grey forewings with a broad brown costal margin as far as the double scarra. 
antemedian line which proceeds from a deep black costal-marginal spot, with black dots and streaks before 
it; cross-vein shaded brownish with black scales behind it; then follows a curved brown shadowy stripe with 
a black dot below the cell; the veins behind the cell are striped black as far as a straight blackish-brown double 
line behind which a narrow brown shadow follows, enclosing white and black vein-dots; a black subterminal 
spot between veins 4 and 5, and a black line above the anal angle. Hindwing greyish brown with white fringe. 
Expanse of wings: 45 mm. Guatemala. Probably the $ of the following postpuncta. 
N. postpuncta Schs. is a smaller species also with whitish forewings which, however, are strewn with post¬ 
light brown, the marginal area dusted light brown, with double brown transverse lines, the median line treble, punda. 
partly shaded with ochre; an irregular brown spot on the cross-vein, the cellular branches are black as far as 
the posterior transverse line behind which there are black and white vein-dots, and a round black spot between 
4 and 5; the velvety black undulate line is irregular and interrupted. Hindwing whitish, veins and margin 
greyish brown. Guatemala. Expanse of wings: 42 mm. 
N. Indiana Grt. (— guttulata Schs.) (143 h). Forewing light grey, somewhat brownish behind the Indiana. 
anterior double transverse line, dusted with reddish yellow in the marginal area; behind the large cellular spot, 
which is bordered by velvety black, follows a dark transverse line widened at the inner margin, and behind 
it a fine straight red-brown line; behind the double postmedian line, which is filled with dark grey, follows 
a row of reddish-brown spots, behind them double black dots and larger dark brown marginal spots. Hind¬ 
wing whitish, blackish-brown outside. Florida, Cuba. 
N. eastmani Schs. is somewhat similar to indiana. Basal part of forewing greyish-white, bordered by eastmani. 
the fine, partly double antemedian line, median area light reddish-brown, bordered by a double dark line 
which is angled on 3 and undulated below the cell; 7 black dots along the centre of the cell; a white post¬ 
median area, strewn with dark, is traversed by a fine dark line, and a brown and black line between 4 and 5; 
distally bordered by a double dark undulate line, then follows a cinnamon-brown shadow with darker brown 
spots; marginal area reddish-brown, distally strewn with white, with dark brown lunules. Hindwing greyish- 
white, veins and margin brown. Expanse of wings: 49 mm. British Guiana. 
N. plumipes Schs. (143 h) has grey fore wings strewn with reddish-brown and partly shaded with green, plumipes. 
with undulated brown transverse lines, a broad brown and grey shadow behind the distal line; a series of 
black dots in the cell. Hindwing brown, whitish towards the base. Venezuela. 
N. biumbrata Schs. is nearest to plumipes in its marking. Forewing silvery grey, dusted darker before Mumbrata. 
the centre and in the marginal area; the antemedian area, behind the fine irregular black transverse line, is 
bordered by a double reddish orange brown line which is sinuate at the costal margin and on the median vein, 
with small black spots at the indentations; discal line whitish, scaled black, a dark crescentiform line behind 
it; postmedian line double, blackish-brown, undulated in the lower portion, a dark brown crescentiform line 
behind it; deep black internerval dots subterminally, blackish-brown marginal dots behind them. Hindwing 
white, veins and margin narrowly blackish-brown. Expanse of wings: 50 mm. Argentina (Tucuman). 
N. olivescens Schs. (= obliquata Schs.) (143 h). Forewing light, grey below the base of the cell and olivescens. 
at the inner margin, strewn darker, brown at the costal margin with a green longitudinal stripe, snow-white 
below it from before the cell-end to the submarginal line, strewn with brown and green towards the costa, 
bordered below by a fine black line; below and behind it the wing is dark green, traversed by the undulate- 
dentate black submarginal line. Hindwing reddish-brown, darker violettish-brown at the margin. French 
Guiana. 
1 N. folia Jones. Forewing brownish ochre mixed with green and strewn with black and brown, black folia. 
at the base with green hair; behind the indistinct anterior transverse line follows a dark shadow forming a 
spot in the cell; a very dark postmedian shadow towards the apex is much narrower above the centre, bordered 
distally by a dentate line. Hindwing yellowish brown. Rio de Janeiro (Corcovado). 
N. forfex Dogn. (143 h). This species, described as a Tachuda, is one of the smallest; brownish-grey, forfex. 
partly dusted with green and strewn with brown, marked like the preceding species, with a large brown spot 
before the double anterior transverse line at the inner margin, a double red-brown transverse shadow behind 
the cell, followed by two blackish-brown spots, the upper one being much larger. Hindwing brownish, lighter 
towards the base. French Guiana. 
N. lophocera Dyar is somewhat larger than forfex, with narrower wings and similarly marked as the lophocera. 
preceding species, grey with green spots, brown in the basal area at the costal margin, with black dots in the 
cell and spots at the inner margin, the distal transverse line quite indistinct, brownish, a blackish subapical 
s pot behind it at the costal margin. Hind wing greyish-brown, lighter towards the base. Expanse of wings: 
U mm. Panama. 
N. longicornis Fldr. (= picta Dogn.) (143 h). Basal half of forewing greyish-green, white behind it, longi- 
brownish at the apex, with double antemedian and median transverse lines, and rusty yellow spots between corms -
