N. tamsi Hopp. A small species with narrow wings. Length of forewings: 11 mm. Wings without tamsi. 
stripes. It cannot be noticed in the only specimen whether the head and abdomen exhibit any yellow colour. 
Uncus delicate, broad at the base, obtuse at the end. The sacculi are bulbous chitine-plates, scantily set with 
cilia. Buenos Ayres. 
N. muelleri Hopp. Stripes of forewing rather indistinct, costa beneath white. Uncus broad, short. The muelleri. 
sacculi are short, feebly arched chitine-walls the anterior edge of which bear one large, crooked or straight thorn 
each on the sides and in the middle. Mexico, Guatemala, British Honduras. A form of this species has black 
middle and hindlegs — f. atripes Hopp. airi-pes. 
N. variabilis Hopp is not easy to determine, as it varies extraordinarily in many respects. Length of variabilis. 
forewings 11—18 mm, width 6—10 mm. In general it is a species with rather small, narrow wings. The uncus 
is a delicate, obtuse triangle. As the sacculi can be rolled up, they vary in shape from one specimen to the other. 
They usually represent small, notched chitine-walls. Widely distributed: Para, Brazil, on the whole Amazon 
River as far as Peru, in Colombia and Venezuela. A form was separated with a broad blackish collar — atri- atricollis. 
collis Hopp, from the Upper Amazon R. 
N. virgo Btlr. Like several other species, it has black tibiae and tarsi. The uncus is short, roundish, virgo. 
broad, delicately chitinized, but edged by broad chitine-listels. Sacculi bent geniculately, with a thorn at the 
end, but of different projections. Texas, Mexico, and Colombia. A form is separated with white middle and 
hindlegs — f. albipes Hopp. Mexico. albipcs. 
N. cretata Grt. is not distinguished as an imago from virgo f. albipes. Only Dyak's statement that the creiaia. 
larvae of virgo and cretata are distinctly different, forces us to separate this species for the present. In case 
of the differences in the larvae being explained as an error, cretata would have to be regarded as the species 
(i albipes being a synonym) and virgo as its form (with black legs), cretata is known from the southern states 
of U.S.A. — Larva, according to Dyar, in the surroundings of Washington, on Cercis canadensis; with long 
white hair, marked with yellow, brownish red, and black. Cocoon in the earth in September, emerging in July. 
N. nevermanni Hopj > is allied to virgo, likewise with black legs. The uncus is longer, almost just as never - 
broad at the end as at the base. Costa Rica, Panama. manm 
N. taurina Hopp has also black tarsi. It is smaller, on an average, than virgo and nevermanni. The uncus iaurina. 
is similarly built as in virgo, somewhat narrower at the base. Very differently shaped, however, are the sacculi 
looking like tiny, basally very broad cow-horns. Mexico, Guatemala. 
N. caprina Hopp. Size very different, length of forewings: 10—15 mm. The uncus is an oval, rather caprina. 
small, delicate lobe. The sacculi are strongly curved horns arising from the sides of an irregularly dentate plate. 
British Guayana, Venezuela, also from the Upper Rio Negro, Colombia. 
N. arietina Hopp, near caprina, with a similarly built uncus. The sacculi are rather large, triangular- arielina. 
roundish plates terminating into short thick horns. From the Amazons: Manaos, Santarem, also from the Rio 
Essequibo in British Guayana. 
N. capreolata Hopp. The uncus is an obtuse triangle framed with thick chitine-listels, according to capreolata. 
which the species may belong near virgo. The sacculi bear one lateral branch each at the end and in the middle, 
but they are of variable shapes. Colombia: Muzo. 
N. truncata Hopp. The uncus is short, very broad, arched somewhat like a hood. Sacculi long, flatly truncata. 
curved, broadly truncated at the end, proceeding from the abdomen. According to the shape of the anellus, 
the species is divided into three geographically separated races: truncata truncata Hojyp-, anellus roundish in 
front, convexly arched, not pointed, bearing a small roundish appendage in the middle. Merida and Caracas, 
Venezuela. — cavata Hopp; anellus more intensely chitinized, broad, concavely arched, gradually pointed cavata. 
in front. North Peru (Rio Charape) and Colombia (Central Cord.). — hastata Hopp. Anellus narrow, intensely hastata. 
chitinized, extended into a long point. South Colombia (Cali, Popayan, Pasto) and Panama. 
N. schausi Hopp. Uncus very broad and short, with a short broad tongue in the middle. The sacculi schausi. 
are distantly separated, falciform horns with long appendages towards the inner sides. Costa Rica: Guapiles 
and Sixola. A rare species. 
N. draudti Hopp. Uncus tongue-shaped. The sacculi are slender, long-hooked clasps, basally widened draudti. 
spherically. The length of the sacculi varies. A common species from Mexico. 
N. obtusa Hopp. Uncus very broad and short, as in schausi, but centrally tapering into a short point, obtusci. 
Sacculi feebly bent, dong, broadest basally, gradually narrower and then again broader and flatter, feebly den-
