53. Genus: Tliyone WTcr. 
Proboscis and palpi very much stunted; G antennae ciliated. Spurs of the tibiae short, on the posterior 
tibiae the middle spurs are absent. Abdomen roughly haired. The long, narrow forewings show exactly the 
same venation as the preceding genus, except the uppermost radial rising from below the upper cell-angle. 
On the hindwing the upper median and lower radial vein are petioled; the middle radial comes almost from the 
middle of the transverse vein, the upper one being petioled with the subcostal. 
T. celenna Schs. (34 n). Body purple black, on the thorax spotted white and with a metallic green celenna. 
head and collar. Forewings white with veins striped purple black, and black spots at the costal margin, behind 
the cell and in the middle of the margin. Hindwings brownish black. Expanse of wings: 30 mm. Brazil. 
T. dremma Dyar (34 n). Head yellow, thorax orange brown. Abdomen light yellow. Forewings dremma. 
orange-yellow, with a yellow median band, bordered with a purple brown on both sides; before and behind 
it the veins are striped carmine. Hindwings yellow-brownish. Expanse of wings: 17mm. Britisch Guiana. 
T. purpurea Jones (34 n) is on the anterior body deep purple brown, with a metallic blue lustre; purpurea. 
on the metathorax there is a yellowish-white spot; abdomen dark brown, posteriorly lustrous blue. Forewings 
purple-brown, at the base and costal margin suffused with a metallic blue; before the middle there are below 
and obove the inner-marginal vein oblique, oblong spo^s of yellowish-white; a similar one near the cell-end, 
and one above it; behind the middle a macular band. Hindwings dark brown. Expanse of wings: 36 mm. Brazil. 
T. trimaculata Jones (34 n). Entirely white, on the forewings with a small black spot on the inner- Irhnacu- 
marginal vein at the end of the basal third and a second spot near the proximal angle; a 3rd spot is situate l ala - 
behind the cell on the middle radial, and one or two very small ones about the middle of the subcostal. Ex¬ 
panse of wings: 25 mm. Castro (Parana). 
T. placida Schs. (34 b) is similarly marked as celerma, but of a greyish-brown ground-colour, and placida. 
much smaller expanse of wings (only 24 mm). Brazil (Sao Paido, Castro [Parana]). 
T. parima Schs. (35 a) is light brown, on the body somewhat mixed with grey, with faded grey pari ma. 
spots on the forewing in the cell-spaces in the basal half, in the cell-end, and before the margin. Hindwings 
light brown. Expanse of wings: 28 mm. Brazil (Sao Paulo). 
T. perbelSa Schs. (34 n) is very differently coloured. Head yellow, collar and thorax orange, abdome.i perbella. 
more ochreous-yellow. The forewings are yellow at the base, and this colour passes from orange and red into 
brown as far as the discal area; then follows a broad, pale yellow median band, behind which the ground-colour 
is again brown, fading away into an ochreous yellow towards the margin; veins in the marginal area dark brown, 
at the base of the costal margin a small black spot. Hindwings pink-yellowish. Expanse of wings: 16 mm. 
French Guiana. 
T. muricolor Schs. (35 a) is unicolorously leaden grey, on the forewing with a slight violet reflection, muricolor. 
Abdomen more greyish-black, like the hindwings. Expanse of wings: 18 mm. Cayenne. -— A somewhat darker 
which, however, certainly belongs to the same species, is before me from Caparo (Trinidad), belonging to 
the German Entomological Museum. 
T. grisescens Schs. (35 a) is very closely allied to muricolor , but somewhat larger, on the body and grisescens. 
wings violettish-grey, abdomen and hindwings somewhat darker. Expanse of wings: 22 mm. Costa Rica. 
T. tincta limps. (35 a) is white, on the forehead, legs and abdomen tinted brownish-grey, antennae tinda. 
curled black. Forewing at the base of the costal margin black; inner-marginal area and under surface blackish- 
brown. Expanse of wings: 26 mm. Bolivia. 
T. melanocera Schs. (35 a) is purely white, with quite black antennae, also the anterior legs and the melanocera. 
extreme ends of the middle and posterior tarsi are black. Expanse of wings: 22 mm. Trinidad, Venezuela, Surinam. 
T. simplex Whr. (= alba Drc., parvita Schs.) (35 a) is entirely of a pure white. Expanse of wings: simplex. 
18 to 22 mm. From Mexico to Brazil. 
54. Genus: Afrida Mschlr. 
A doubtful genus. Moeschler, who founded the genus, placed it to the Lithosiidae, Hampson to the 
Nolinae ; quite recently Dyar has placed it to the Noctuidae, since the costal vein of the hindwing, contrary 
to Hampsoy’s assumption, does in fact not rise from the middle of the cell, but anastomoses with it only for 
a short distance. If we deal with the genus here, it is only not to introduce an innovation for the present. — 
Proboscis developed; the porrect palpi extend beyond the forehead; tibiae with long spurs. Venation of the 
forewings similar as in the preceding genus, but the 3rd subcostal vein is absent and the uppermost does not 
anastomose with the costal. Veins of the hindwings likewise the same as in the preceding except the course 
of the costal. Whereas Hampson’s Catalogue mentioned only 4 species, Dyar who studied the genus very closely, 
increased the number to more than 2 dozen species which, however, are difficult to separate. 
A. tortriciforniis Mschlr. is greyish-white, beneath more blackish. Forewing with a dentate ante- tortricifor- 
median line, not reaching the proximal margin, with a black subcostal dot on its proximal side. An antemedian,
