Rh. niathani sp. n. Very similar to rufaria, (3 a) of which I should have supposed it a form, but 
that the hindwing is markedly bent, about as in endognoma. Forewing with the markings darker, the ante- 
median rather broad, accompanied proximally by a patch of ochreous suffusion, the subterminal strong, 
recalling that of Irifasciata, but more proximal. Hindwing with the central suffusion less reddish and not ex¬ 
tended outward anteriorly, altogether more as the hindwing of minor. Ecuador: Balzapamba, November 
1893 to February 1894 (M. de Mathan), 1 ^ ex coll. Oberthur. 
Rh. niepelti sp. n. (3 a). 42—46 mm. Very distinct in the sinuous distal margin of the forewing, ex¬ 
tensive clay-coloured suffusions, strong grey bands and other details. Terminal joint of palpus not long. 
Forewing with 1st subcostal free (type) or anastomosing with costal (paratype). Underside whitish, on forewing 
with green suffusion in cell and as far as the postmedian band, on both wings with diffuse green postmedian 
and fainter subterminal, forewing with cell-dot, hindwing with some red-brown scaling close to apex. West 
Colombia: Rio Micay, February—April 1928, 2 <3>d> in coll. Joicey, received through Mr. W. Niepelt. 
Rh. ustiniargo Warr. differs from roseipalpis (5 a) in having a large dark livid-brown patch occupying 
nearly the entire distal area of the fore wing from the radials to the anal angle and a small apical patch on 
the hindwing above as well as beneath. Huancabamba, Cerro de Pasco, only the type known. 
Rh. rothschildi Warr. (3 a). Easy to recognize by its large size and copious markings. Chiriqui, Panama, 
apparently not variable. 
Rh. gaujoniaria Dogn. Very distinct in its blackish face and palpus, sombre tone, and bright rose-colour 
of the patch at anal angle of fore wing. Fore wing with some rosy spots at base in place of the antemedian 
line, two yellow dots instead of the posterior subterminal spot. Hindwing rounded. Ecuador: Loja. 
B. Hindtibia of without hair-pencil and with proximal spurs obsolete. 
Rh. exquisita Warr. 40 mm. Different from all the others species in shape, the forewing being sub- 
falcate. Markings somewhat as in rufaria (3 a); antemedian line of forewing brighter red, incurved between 
the two folds, tornal spot larger and brighter, the markings in front of it more blackish, continued to 1st radial; 
hindwing with bright red apical area, a narrow red band immediately outside the blackish antemedian one, 
the dentate red postmedian line more distally placed than in the allies. Carabaya, S.E. Peru, very rare. 
Rh. trifasciata Warr. Shape of rothschildi (3 a) but much smaller (49 mm.). Abdomen green. Forewing 
similarly marked to that of rothschildi but with costa red at base, antemedian line shorter, more acutely 
angled, postmedian less acutely dentate, its posterior yellow patch smaller (about as in brunneipalpis [3 a]). 
Hindwing with the subbasal grey band broadened, containing a black discocellular lunule, two characteristic 
purple bands, the postmedian sinuous, thickened about the fold, the subterminal parallel with termen, 
tapering at both ends, not reaching abdominal margin. Carabaya, Agualani: described from a single $. 
2. Genus: Efemoria Hh. 
A group of species from North America, probably not entirely homogeneous nor satisfactorily classi¬ 
fied, which has hitherto been kept separate from Racheospila on the ground of the less elongate $ palpus, 
especially as regards the terminal joint, which is often quite small in both sexes. As the relatively few known 
larvae suggest possible groupings which would be more fundamental, it would be premature to merge them, 
or to attempt any essential re-classification in the present state of our knowledge. 
N. (?) capys Druce (5 a) is unknown to me and I can add nothing essential to what is shown by the 
figure. Possibly related to Racheospila mustela, in which case its transference to the present genus was not 
justified. Founded on a <$ from Las Vigas, Mexico. 
N. bistriaria Hh. (= bifilata Walk.) (5 a). This species and the following may be distinguished from 
all the rest by their red-brown coloration. 3rd joint of $ palpus not very short. Hubner’s type was from 
Georgia and the range, so far as I am aware, is not a wide one. 
N. brunnearia Pack. Closely similar to bistriaria (5 a), of which it was formerly believed to be a synonym. 
Me. Dunnoitgh, however, has pointed out that it is rather smaller and has an interrupted red terminal line 
and slightly chequered fringe, which are wanting in Hubner’s species. Described from W. Virginia, Central 
Missouri and Texas, but reaches Philadelphia, where it is recorded that fresh specimens show a decided tinge 
of green, overlaid with reddish scales. I suspect also that records of “ bistriaria ” from New York State and from 
Kamloops B. C. belong here. The larva is described as short and thick, with large triangular lateral flaps, some¬ 
what reminiscent of those of Anisozyga and some other Old-World genera. On Juglans nigra. 
N. mimosaria Guen. ( = tractaria Walk., venustus Walsh, coniferaria Pack.) (5 a) is one of the best 
known species, widely distributed in eastern America from Canada to Florida. Face reddish. Terminal joint
