maculae finely surrounded with red-brown; a brown median line extends through the reniform macula, being 
flawed in an obtuse angle on the median, as far as the proximal margin; the undulate line extends straight 
downwards from the apex and terminates right before the anal angle; it is black, distally shaded with a faded 
colour. Hindwing of a pure white, semi-transparent, with a fine dark marginal line. Antennae feebly serrate 
and ciliated. Mt. Tolima and Quindiu Pass (Colombia). 
N. differens Drc. (= vellerea Drc. nec Schs.) (18 d) is very easily recognizable by the contrastingly different. 
rusty-brown discal area; the forewing is for the rest deep purple grey, the posterior transverse line is double, 
filled up with a light wood-coloured brownish, not quite reaching to the costal margin; the undulate line con¬ 
sists of lustrous coppery spots projecting far towards the base on the discal fold. Hindwing brownish, towards 
the margin darker. Mexico, Costa Rica, Panama. 
N„ noctivaga Schs. Forewing violettish-brown, in the discal area between the cell and submedianly nodivaga 
tinted bronze, with dark brown transverse lines being on the averted sides bordered with light brown; the ring- 
macula is large, round, the reniform macula large, both dull lilac-brown, the latter surrounded with dark; the 
undulate line consists of light bronze-brown crescentiform spots shaded with dark brown; at the ends of the 
veins very fine white dots. Hindwing brownish-black with darker veins; fringes brownish-black, at the ends 
whitish with a fine light brownish basal line. Expanse of wings: 37 mm. Costa Rica. 
N. vellerea Schs. (= cedica Drc.) (18 cl) looks very much like congenitalis, but it is easily discernible vellerea. 
by light hindwings and plain, ciliated antennae; the discal area, particularly below the cell is darker and termi¬ 
nates above the proximal margin by the connection of the two fine double transverse lines. Hindwing whitish, 
at the margin feebly brownish. Mexico to Panama. 
N. persimilis sp. n. (18 d) looks extremely similar to vellerea , but it is larger, of a purer purple grey, pershuili*. 
without the slight coppery lustre of the preceding; the anterior transverse line is entirely absent, only marked 
by the contrasting colours of the purple grey basal area and the velvety brownish-black discal area which grows 
lighter towards the proximal margin; the posterior transverse line is likewise quite extinct, softly bent, parallel 
to the distal margin, without the whitish indentations on the veins, which are noticed in vellerea; behind it a 
light violettish-brownish area; marginal area darker purple grey, strewn with single white scales which are 
somewhat more densely strewn in the undulate line and proximally shaded with a slightly darker colour. Hind¬ 
wing more extensively white than in vellerea, the margin but very narrowly brownish. Mexico. 
N. stellans sp. n. (18 d) is very much like differens in the marking, but whilst in the latter species stellans. 
the discal area is much lighter in contrast with the darker purple grey basal and postmedian areas, the discal 
area in stellans is coppery brown with a deep bronze lustre as in some of our Plusia (concha), the whole marginal 
area being the same, the rest of the wing of a lighter purple grey; the similarly coloured maculae are below 
broadly confluent; the transverse lines together form a bent line at the proximal margin and terminate the 
discal area before the proximal margin, whereas in differens it ends broad below at the proximal margin and 
the transverse lines are not united; the double posterior transverse line is filled up with light; the undulate 
line exhibits some small whitish lunae at the costal margin and near the anal angle. Hindwing brownish, 
in the disc semi-diaphanous, on the veins and margin darker. The $ is very much darker. Mexico to Costa Rica. 
N. oomae Dyar (18 cl) has quite a different marking, much broader forewings of purple-blackish oomae. 
colour, in some places dark flesh-coloured reddish, particularly at the costal margin between the beginnings 
of the double dentate transverse lines and in the filling of the postmedian line in its proximal half; we notice 
the complete Noctuid marking, the large broad coniform macula being surrounded with black, the reniform 
macula distally pupilled white; undulate line light, fringes crossed by a lighter colour. Hindwing light yellowish- 
white, at the margin broad brownish-grey with a darker central dot and a transverse line behind it. Mexico. 
N. conservulodes Drc. (18 c) and the following dissentanea represent quite a different type. Fore- conservulo- 
wing golden brown, strewn darker, with grey, indistinct transverse lines, the large purple grey maculae in yellow- des * 
ish-white rings and surrounded with black flow together below, above the coniform macula with an oblique 
yellowish-white streak. Marginal area behind the yellowish undulate line very light purple grey; in the sub¬ 
terminal area above the upper radial branch a pinkish-grey strigiform spot. Hindwing yellowish-white, on 
the veins and margin brownish. Colombia. 
N. dissentanea sp. n. (18 b) in its exterior is very much like conservulodes, but of a somewhat different dissentanea. 
structure, unless the small foveolate hollow in the centre of the round, slight convexity of the frons be artificial. 
Distinguished by its purer purple-grey, not red-brown ground-colour, in the discal and subterminal areas deep 
purple-brown with a distinct dentate posterior transverse line which is silvery white below the costal margin 
and above the proximal margin, otherwise distally bordered with purple grey; in the subterminal area beside 
the subapical light strigiform spot with a white streak below the lower radial branch; the reniform macula is 
smaller and more slender, on the median proximally confluent with the oblique ring-macula, above the coniform 
macula with a narrow, white, harpoon-shaped spot. Hindwing white, at the margin smoky. Bolivia (Cuesta 
de Cillutincara), described according to 1 $. 
N. fluminalis Dogn. is still more conspicuously coloured and marked than the preceding, purple- fluminalis. 
grey, strewn with chestnut-red, with a deep blackish-brown irregular discal spot, towards the costal margin 
tridentated, towards the proximal margin bidentated, for the greatest part finely bordered with yellowish-
