b) Yellow colouring different: argyrorrhoea (abdomen white, argyrorrhoea f. pruinosa 
(also the vertex white), cingulata (without yellow), zikaniana (vertex white, but the tufts around the antennae 
yellow), foliata (without yellow), fuscoapicata and heringi (without yellow), hadaca (abdomen white), damana 
(vertex yellow, but the tufts around the antennal base almost white, colouring of abdomen unknown), glabra 
(variable, abdomen white or yellowish, vertex yellow, or yellow with a white tuft around the antennae, or all 
white), albilineata (vertex white, Imt the tufts at the antennal base yellow), pampana (abdomen white). The 
yellow colouring of tamsi is unknown. The yellow colouring of the abdomen is not to be confounded with the 
bands of the abdominal rings with parallel, frequently yellow bristles. 
c) Fore wings without transverse stripes: albilineata, glabra, pampana, miasma, 
foliata, miasmoides, tamsi, heringi, argyrorrhoea. The limit is not distinct, some species exhibiting hardly noti¬ 
ceable transverse stripes. 
Finally, many species can be determined bv their habitat, since most of the species are confined to 
a certain range. 
We begin with three species forming together with the already mentioned nigrovenosa and beggoides a 
natural group by their 10th ventral segment (uncus) being trilobate, presumably produced by the uncus having 
grown together with the socii, by reason of which they were originally placed to the Mesoscia: 
N. albilineata Hopp (161 a). Forewing thinly scaled on the surface, but intensely scaled on the veins. 
Brazil: Esp. Santo, Itatiaya, Sa. Catharina. 
N. glabra Hopp is a small species with smooth, not striped forewings. The neuration varies somewhat. 
Sacculi long, bent, basally widened, gradually tapering at the end. A typical representative of the Argentine 
Pampas. 
N. pampana Hopp is closely allied to glabra, likewise confined to the Argentine Pampas; externally 
recognizable by the absence of the yellow basal tuft of the abdominal dorsum. Uncus large, straightly trunc¬ 
ated at the end, lateral tips pointed. The sacculi are longish, pointedly ending horns exhibiting a little swell¬ 
ing basally inside. 
N. argyrorrhoea Hbn. (= Carama pura Btlr., Sulychra argentea Btlr.) (161 a) is the most common species 
distributed from Texas to Buenos Ayres. Vertex yellow, abdomen without yellow hair. Forewing smooth, 
without transverse stripes. The males differ much in size, length of forewings: 11—17 mm. The costa of the 
forewing beneath exhibits a black streak not extending to the apex, but this streak is sometimes absent. The 
males are often also discernible by the sacculi projecting somewhat from the abdomen and being bent like a 
knee towards the uncus; the harpes are likewise bent like a knee, but towards the saccidi. —■ pruinosa Berg 
(— Carama butleri Baker, Trosia euthula Dyar) represents only a form of this species characterized by its pu¬ 
rely white vertex. This form is by no means geographically confined, but to be noticed wherever the typical 
form lives. 
N. vesta Schaus (161 a). The forewing of this small species shows 4 or 5 distinct transverse stripes at 
equal distances, extending from the inner margin to the posterior edge of the cell. The uncus is a small roundish 
club, spherical at the end. Brazil: Amazons, Esp. Santo, Rio de Janeiro, Itatiaya, Parana. 
N. cingulata Jones (161a). Forewing intensely striped, therefore with a bright silvery gloss, vertex 
yellow, abdomen with bright orange ringlets, but purely white hair. The uncus likewise ends spherically, but 
it is longer than in vesta. Harpes short and broad, straight at the end. Brazil: Alto da Serra (Sao Paulo) and 
Itatiaya. 
N. hadaca Dyar has likewise a yellow vertex, striped forewings, and a purely white abdomen, which 
combination is not to be noticed in the other white species of Norape. The uncus is long here, pointed lancet¬ 
like, thin and flat, the sacculi are stout, long, curved in the basal part, spherically thickened basally. A rare 
species. Mexico. 
N. zikaniana Hopp (161 a). A species with remarkably red antennae, reminding us of the genus Aitho- 
rape which, however, is without any yellow colour. The vertex is white here, but the tufts around the antennae 
are bright yellow. Abdomen dorsally suffused with yellow. The uncus has the shape of an oval leaf. Brazil: 
Rio de Janeiro, Itatiaya, 8a. Catharina; presumably still farther distributed in South-East Brazil. 
N. foliata Hopp is a small species, the smooth, stripeless foiewings being about 11 mm long. Without 
any yellow colour, therefore similar to heringi externally. Uncus of the approximate shape of a narrow ivv- 
leaf. Sacculi broad basally, with slender, hook-like ends. Only 1 specimen known from Cucuta in Colombia, 
near the frontier of Venezuela.
