reaching termen; line on hindwing as above. The venation agrees with Psychocampa but the fore wing is simply 
acute, the outer margin straight, slightly inbent. Expanse: male, 28 mm. Mawajo, Amazons. 
P. bibula Dogn. (87 c). Female-. Body and wings drab, more of a light drab before the line; a faint darker 
antemeclial shade; line fine chestnut brown; cilia pale drab grey tipped with white. Forewing: an obliquely 
curved hyaline spot at discocellular; line obliquely downbent, slightly rounded below vein 8 and then parallel 
with termen; apex above vein 8 chestnut brown; termen thickly mottled with white scales. Hindwing: line 
postmedial, straight; termen as on forewing. Wings below drab grey, with darker terminal suffusions below T 
apices, tornus, and anal angle. Forewing; hyaline spot with a dark streak outwardly. Hindwing: a round fuscous 
spot at discocellular. Apex of fore wing not acute, the outer margin slightly rounded. The species is allied to 
mawaja Dogn. but can hardly be the female of that species. Expanse: 36 mm. Obidos. Amazons. 
4. Genus: Itoelofa gen. nov. 
Male: Antennae bipectinate on basal half, terminal half serrate. Palpi short, porrect. Tibiae hairy, 
hind tibiae with short terminal spurs. Forewing broad, the apex rounded, termen slightly sinuous; vein 2 from 
beyond middle of cell; 3 and 4 slightly apart from lower angle; 5 from middle of discocellular; 6—8 stalked; 
9 and 11 from cell. Hindwing: costa and termen rounded; vein 2 from near angle; 3 and 4 from lower angle; 
5 from middle of discocellular; 6 and 7 from upper angle; 8 upcurved from base of cell. 
Type: /'. olivia Schaus. 
R. olivia Schs. (87 c). Male : Head hair brown. Collar, thorax and abdomen vinaceous fawn. Wings to 
line, and on forewing to apex fawn color; terminal space light vinaceous fawn irrorated with small drab scales. 
Forewing: a round vinaceous buff spot at end of cell: outer line double, the first line chestnut brown, outcurved 
on costa, almost vertical from vein 8, the second line fuscous outbent along vein 8 to thermen, the space 
between deep vinaceous grey. Hindwing: line as on fore wing, postmedial, almost straight from costa to inner 
margin close to angle. Wings below slightly paler, the discal spot on forewing outwardly edged with chestnut 
brown. Expanse, male, 48 mm; female, 56 mm. Paramo de Guasca, Colombia. A specimen from the Berlin 
Museum is labelled apicistriga Weym. for which I have no reference. 
R. maficia sp. n. (87 c). Male: Body pinkish cinnamon; anal tufts fuscous. Wings to line purplish 
cinnamon buff; line fuscous, outwardly broadly pale vinaceous fawn; termen narrowly purplish cinnamon 
buff; cilia shortly tipped with pale vinaceous pink. Forewing: a fine darker outcurved antemedial line; an 
almost round hyaline spot, crossed by discocellular, dark edged, with a projection towards costa containing a 
few white scales; a slight dark line from costa to outer line which is upcurved to termen above vein 8, below 8 
almost vertical to inner margin. Hindwing: the line postmedial, straight to anal angle. Wings below very 
similar to olivia but the line single, and with the hyaline spot in addition. Expanse: 42 mm. Petropolis, Brazil. 
Type in the Berlin Museum, sent by Dr. Hering for examination. 
R. hegewishi Drc. (87 c). Male: Body vinaceous pink, the anal hairs black. Wings to line pale vinaceous 
pink, the termen pale cinnamon pink, irrorated with fuscous chiefly on hindwing; the line fine, mikado brown; 
cilia pinkish cinnamon tipped with black towards apex of forewing. Forewing: a sinuous white line on disco¬ 
cellular edged with avellaneous; line outbent, very faint on costa, angled on vein 8, the space between veins 
8 and 10 hair brown to apex, below vein 8 the line is slightly inbent, from below vein 6 outwardly edged by 
a white line and then by a line of denser fuscous scaling. Hindwing: line as on forewing postmedial to anal 
angle. Wings below pale ochraceous buff with small dark irorrations. Forewing: light pinkish cinnamon out¬ 
wardly edged with fine black scales. Hindwing: the line only visible in transparency and preceded by a faint 
pinkish buff line. Expanse, male, 36 mm; female, 45 mm. Jalapa, Mexico. The type, a female, is in the Berlin 
Museum. The characters agree with olivia , but the apex of forewing is bluntly produced. 
R. narga Schs. ( = maera Schs.) (87 c). Male: Head and thorax brownish drab. Abdomen light vina¬ 
ceous drab dorsally suffused with flesh-ocher; anal hairs black. Forewing to line brownish drab with a few 
black scales; a round whitish spot irrorated with rufous at end of cell, darker edged, a small similar spot at 
cell between veins 2 and 3, and a still smaller white spot between veins 4 and 5 at cell; line dark vinaceous 
brown continuing from angle to termen above vein 8, the line fainter on costa where outbent and excurved 
to angle with a small pale shade above it; space beyond line white, terminally suffused with apricot buff with 
a series of small triangular black spots on veins just beyond line. Hindwing slightly paler, the costa light buff; 
a fine dark point on discocellular, line postmedial; termen as on forewing. Wings below paler with the same 
general pattern. Expanse, male, 39 mm. French Guiana; Joinville, Brazil; Ponte Nova, Amazons.
