R. dentata Dijar (32 1) is a greyish-brown species with a finely dentated anterior, and strongly 
dentated posterior transverse line and a round dark spot in and below the middle of the cell; undulate line 
indistinctly darker. Expanse of wings: 24 mm. Arizona. 
R. antennata Btlr. (= snelleni Btlr. $) (32 1) is very similar, much lighter, more yellowish-brown, 
the posterior transverse line is not dentate, but inwardly a dentate line runs parallel to it. Hindwings white, 
towards the margin brownish. Expanse of wings: 18 mm. Amazon. 
R. divisa Schs. (32 k). The forewings are in the basal half white, at the costal margin dusted brown 
and black, in the distal half grey, strewn with black, with a white apical spot; the anterior transverse line 
is indistinct, the posterior one broken up into dots, inwardly dusted darker blackish-brown; an ante- 
marginal, irregular undulate line; large heaps of scales are situate in the cell near the base, in the middle and 
at the end of it. Hindwings whitish, towards the margin brownish. —- In natama Schs. the marginal area 
is much darker brown, strewn with black and white, in fusca nom. nov. (= ab. 2 Hmps.) the whole thorax and 
forewing are unicolorously covered with brown. Expanse of wings: 20 mm. Brazil. 
R. divisoides Schs. (32k) is a very similar animal; the forewings are more uniformly white, at 
the costal margin and in the marginal area less dusted brown with more distinct transverse lines, the anterior 
one being distinctly dentate; the dentate median line more indistinct. Fringes speckled white and brown. 
Hindwings more uniformly brownish-grey. Expanse of wings: 18 to 22 mm. From French Guiana and Brazil 
(Rio de Janeiro, Santos). 
R. arana Schs. (32 f) is light brown, on the vertex white, on the thorax and the costa of the forewing 
at the base and before the apex strewn with greenish-black scales; in the middle of the cell and at the end 
there are large heaps of yellowish scales. Transverse lines distinct only near the costal margin, farther below 
dying away or broken up into dots, the posterior one double. Apex of the wing spotted white. Expanse of 
wings: 24 mm. Brazil. 
R. patina Drc. (32 e). Forewings brownish-grey, strewn darker, with black costal-marginal spots 
near the base and at the upper cell-end, the latter triangular, on it and in the middle of the cell there are large 
heaps of black scales; the posterior transverse line is broken up into dots, and before it there is a dentate 
transverse line; undulate line indistinctly dentate, behind it black marginal dots. Hindwings brownish-grey. 
Expanse of wings: 20 to 30 mm. Costa Rica. 
R. plumatella Drc. is very similar, distinguished by its larger size and lighter hindwings. Expanse 
of wings: 30 mm. Guatemala. 
R. rodea Schs. (32 e) is likewise similar; forewings white, dusted brownish-grey, marked almost the 
same; the middle costal-marginal spot, however, is square and not so deep blackish-brown; the scaled spot 
in the middle of the cell is removed more to the end. Hindwings white, towards the margin brownish or 
quite greyish-brown. — - garuba Schs. is of a purer white, scarcely dusted darker. Expanse of wings: 18 to 22 nun. 
Brazil (Sao Paulo; Castro; Parana). 
R. flaviscapula spec. nov. (32 f) belongs to the same group. Head and thorax white, shoulder-covers 
ochreous-yellow. The white forewings are densely dusted light brown; the scheme of markings is the same 
as in the preceding species, but the sharply dentate transverse lines are much less distinct, their course almost 
only indicated by long, black vein-streaks. Very characteristic are the 3 small heaps of scales at the base, the 
middle and end of the cell; blackish-brown, towards the margin broadly ochreous-yellow. Hindwings light- 
grey, towards the margin smoky brownish. Expanse of wings: 22 mm. 1 £ from Pacho (Colombia) in the Coll. 
Fa ssl. 
R. minuscula Z. (= phylla Dyar, minor Dyar, patina Drc. part.) (32 f) differs by the longer, more 
stretched shape of the wings, the markings otherwise very much like the preceding. The wings are dusted 
darker brown and densely strewn with black; instead of the basal costal-marginal spot there are only two small 
dots. Hindwings brownish-grey. — fuscula Grt. (= conspicua Dyar) is a larger and still darker brown form. — 
postalbida form. nov. (= subsp. 1 Hmps.) may be called a form from Bolivia with entirely white hindwings 
being brownish only at the apex. The species is otherwise widely distributed in North America (Texas, Colorado, 
California, Arizona), Mexico and Panama as far as Colombia. Expanse of wings: 24 to 30 mm. — The larva 
living on different oaks, is cream-coloured on the dorsum, beneath lighter with dark brown subdorsal bands, 
which are connected by transverse bands on the rings 7 and 11; it is light-haired, on the 3rd ring very 
long and pupates in a cymbiform web covered by bark. 
R. punctilinea spec. nov. (32 f) is another species approximating patina. Forewings of a much purer 
white, only very scantily strewn with black. Marking the same, but all the transverse lines are on the veins 
thickly dotted black; the parallel line accompanying the posterior transverse line inside, is very much approached 
and forms on the inner-marginal vein a pointed tooth directed towards the base. Fringes of a yellowish lustre, 
in the basal half speckled brownish-grey. The white collar exhibits a blackish-brown transverse band. Hindwings 
brownish-grey. Expanse of wings: 26 mm. 1 $ from Orosi (Costa Rica) in the Coll. Fassl. 
R. stilbina spec. nov. (32 f) is of a purer grey than minuscula with entirely white hindwings, with 
a fine, dark marginal line; very characteristic are the two thick, black transverse lines: the anterior one almost
