Type: T. amaryllis Sells. 
T. amaryllis Schs. (= alboflava Dogn.). (86 g). Male : Head and collar white, the latter edged in front and 
behind with amber yellow. Body massicot yellow, with amber yellow transverse lines on abdomen dorsally. 
Wings amber yellow; cilia tipped with white. Forewing: costa white; an antemedial and a postmedial buffy 
citrine broad line, edged on either side with white; outer space with the veins broadly wax yellow. Hindwing: 
antemedial line nearer base, downbent, not edged with white; postmedial line as on forewing, straight to inner 
margin nea anal angle, outer space as on forewing. Forewing below with the line more remote, the veins near 
termen more broadly dark shaded. Hindwing below with the line visible in transparency. Expanse: 29—32 mm.

8. Genus: Vanenga gen. n. 
Male : Antenna bipectinate diminishing near tips. Frenulum present. Palpi very short, slender, hairy. 
Forewing: apex rounded; termen very faintly incurved; vein 2 from middle of cell; 3 before angle; 4 from lower 
angle; 5 from middle of discocellular; 6 from upper angle; 7 and 8 stalked. Hindwing: termen rounded; vein 2 
beyond middle of cell: 3 before angle; 4 from angle; 5 from middle of discocellular; 6 and 7 from upper angle. 
Genitalia near those of Lacoscma. 
Type: V. mera Dogn. 
V. mera Dogn. (86 g). Male : Body and wings pinkish cinnamon; a few black scales on terminal space; line 
hair brown outwardly shaded with purplish clay colour, more broadly on hindwing, from apex of fore wing to

orange; a black line on discocellular; line hair brown, faint, postmedial, slightly outcurved on costa; terminal 
space vinaceous cinnamon suffused with olivaceous. Hindwing below to line light pinkish cinnamon, the line 
medial; terminal space as on forewing. Female differs in having the line on forewing above postmedial, as on 
under side of male. Expanse; male, 22—32 mm; female, 29 mm. Obidos, Amazons; Blumenau, S.E. Brazil;

9. Genus; Maeessoga gen. n. 
Male : Antenna with long bipectinations diminishing slightly at tip. Frenulum present. Forewing 
broad; apex bluntly acute; termen slightly sinuous; vein 2 from before middle of cell; 3 well before angle; 
4 from lower angle; 5 from middle of discocellular; 6 from upper angle; 7 and 8 on short stalk. Hindwing: vein 
2 from beyond middle of cell; 3 close to angle; 4 from lower angle; 5 from middle of discocellular which is 
oblique; 6 and 7 from upper angle. 
Type: M. fabia Drc. 
M. fabia Drc. (88 f). Male: Body above flesh-ocher shaded with rufous. Forewing apricot buff to line; 
base narrowly and costal margin cream colour; an antemedial ferruginous lunular line from a black point on 
costa, the lunules filled in with yellowish; a large round cream colour spot on outside of discocellular; outer line 
from a black point on costa, very fine, dark, oblique to vein 7, angled and inbent to inner margin beyond middle, 
cinnamon brown, narrow; terminal space mostly cream colour; a small ochraceous tawny shade on termen opposite 
angle of line and some apricot buff shading beyond line; a terminal line and base of cilia buckthorn brown, tips 
of cilia white. Hindwing: line postmedial, slightly thicker than on forewing outwardly edged with buff yellow, 
followed at middle by a broad buckthorn brown shade, partly suffusing with a vinaceous rufous shade along 
termen; base cream colour edged by a curved ferruginous line; inner margin broadly cream colour, and a large 
similar patch at apex. Both wings well irrorated with black scales. Wings below largely pale maize yellow 
irrorated with black scales; the line subterminal, fuscous, deeply dentate and partly crenulate; anterior half 
of forewing to line tawny, and its discal spot pale maize yellow; termen of hindwing largely tawny. Expanse: 
male, 45 mm; female, 60 mm. Panama (type in Berlin Museum); Carabaya, Peru; French Guiana. 
M. aelfrida sp. n. (88 f). The following three forms probably represent a single species. They are not 
represented in the National Museum so it is impossible to have genitalia slides made for examination. Male: 
Head and collar light pinkish cinnamon. Thorax, abdomen and wings pinkish buff, all with a few scattered 
black scales. Forewing: a wavy vertical antemedial cinnamon line from a small black spot on costa; two hyaline 
spots at discocellular separated by vein 5, inwardly edged with cinnamon, outwardly with black; line fine, 
fuscous black, outbent from a small black spot at costa, angled at vein 7 and faintly inbent; termen partly 
suffused with cinnamon. Hindwing: a cinnamon antemedial shade; line as on forewing, postmedial; termen 
narrowly orange cinnamon. Wings below similar with pinkish cinnamon suffusions in cell of forewing, and 
on termen of both wings. Forewing: the line visible in transparency, very fine, from vein 6 to vein 2, from
