tate on the inside and slightly bent in the end-part, distinctly interrupted narrower to the roundish-truncate 
end. Rather widely distributed: Bolivia, on the Upper Amazon R., Uberaba (Minas Geraes). 
N. damana Hopp. Vertex yellow, almost white around the antennae. Forewing very indistinctly striped. 
It is not known, whether the abdomen shows any yellow colour. The only specimen at hand has an uncus similar 
to puella and miasma. The large harpes are basally broken up into bands. Sacculi short, roundish obtuse, 
scantily haired, passing broadly knee-shaped over into the tegumen, which is interrupted between them, and 
connected with the base of the harpes by a band. Alto Parana (Argentina, Paraguay). 
N. testudinalis Hopp. Uncus basally broadly divided into two rather narrow branches, with a short 
roundish lobe in the middle. Harpes extraordinarily long, projecting far beyond the uncus. The sacculi are 
large dark brown, smooth, glossy chitine-walls with slight details, round at the end, broadly angled on the 
insides and from there to the base broadly undulate. AVest Colombia: Rio Micay and Bella Vista near Tumaco. 
numerous. 
I nsi nuata- Group. 
The species of this group can be comprised by the similar structure of the uncus and are probably related 
to each other. 
N. insinuata Hopp has blackish tibiae and tarsi, and the costa of the forewing beneath is blackened 
almost to the apex. The uncus is an oblong lobe broadly rounded in front, dorsally with two bare narrow pa¬ 
rallel ridges. The sacculi viewed ventrally look almost just like those of plumosa-angustior, but dorsally seen 
they are sharply flawed, the end-part more or less broadly lancet-shaped. From the Upper Rio Negro, Colom¬ 
bian Eastern Cordilleras, and from Peru, Carabaya. 
N. cornuta Hopp has also blackish tibiae band tarsi, and a blackened costa of the forewing beneath. The 
uncus widens gradually at the base, but it is otherwise similar to insinuata, and the species may be considered 
as a race. The sacculi differ from insinuata in the end-part, ventrally seen, being uniformly narrow and termi¬ 
nating into a small, interrupted, still narrower end-part. From East Ecuador, El Rosario, Rio Pastazza. 
N. consolida Hopp has white middle and hindlegs, the costa of the forewing beneath is white. The 
uncus is flatter and shows a broad bare zone dorsally in the end-part at that place where a narrow raised double 
ridge is to be seen in insinuata. The sacculi, when seen dorsally, likewise exhibit a flaw which, however, is situate 
in the basal third, the remaining larger part of the sacculi is tapering only quite in front and thereby makes 
a very clumsy impression. Bolivia, Chulunrani. 
N. cathara Dyar. Middle and hindlegs grounded black, but covered with white scale-hairs. The species 
is smaller on an average than plumosa-angustior, with less distinct transverse stripes on the forewing, the an¬ 
tennae more red. According to the uncus, the species belongs to the insinuata- group, it is somewhat winged, 
widened at the base. Sacculi very similar to plumosa-angustior, without the sharp flaw of the insinuata-species, 
still more pointed at the end than angustior. Paraguay. 
Plumosa- Group. 
This group can also be comprised owing to the similar structure of the uncus which is rather flat, long, 
narrow, truncate at the end, thus of the approximate shape of a short needle-leaf of a fir-tree. 
N. plumosa Btlr. Sacculi long, slender, bent, proceeding from the abdomen, suddenly tapering at the 
end into a bent point. Legs blackish. Brazil: Para and Lower Amazon R., Guiana, Venezuela. The size of 
the species is rather variable, length of forewings: 15—19 mm. — biacuta Hopp. The ends of the sacculi have 
two short points. Middle and hindlegs blackened or white. Bolivia, Peru, Upper Amazon R. and Colombia 
(Muzo). — angustior Hopp. The sacculi terminate narrow into a gradually narrowing, less bent end-part. Legs 
Vhite. Brazil: Rio de Janeiro, Itatiaya, Minas Geraes, Sa. Catharina. A common species. 
N, jordani Hopp is allied to the plumosa-foiras in the structure of the uncus. Middle and hindlegs 
blackish. Sacculi thicker, but shorter, and the end-part is distinguished by a small, less cliitinized tongue set 
with touch-cilia, and bv a small exterior intensely chitinized appendage. Only 1 specimen known, from French 
Guiana. 
Walkeri- Group. 
This group approximates plumosa in the uncus which is very similarly built, narrow, long, somewhat 
thicker. Besides, the species united here form an interesting series of development in the shape of the
