shadow; fringes black, on the ends of the veins traversed light by the dentate terminal line; hindwing blackish- 
brown, fringes as on fore wing, anal tuft intermixed with ochreous. According to a $ from Cali (Colombia). 
T. sublucana sp. n. (86 b). The £ exhibits a greyish-brown body; the wings are lighter, more brownish, sublucana 
with fine dark veins, 5 broad, darker brownish, undulating, indistinctly defined transverse bands, 2 antemedian 
and 3 postmedian ones, beginning much darker below the costal margin; at the cell-end there is a thick blackish 
spot; distal margin behind the subterminal line likewise darker; before the undulated fringes there is a fine 
dark limbal line. Hindwing without markings light brownish, at the costal margin somewhat darkened. Accord¬ 
ing to 1 $ from Brazil, habitat not mentioned; type in the Berlin Museum. 
T. nigrescens Drc. (= nigricolor Dogn.) (80 e). Hitherto only SS seem to be known. Black, on the nigrescent 
wings scantily scaled; a fine marginal line strewn with whitish extends on the ends of the veins into the fringes 
as in sublucana ; a subtermidal line, occasionally a more or less distinct postmedian line, indicated by white 
dots on the veins. Single white hairs are in front on the forehead and collar, as well as at the base of the 
abdomen; ventrum yellowish-white. Colombia, Bolivia. 
T. arpiana Schs. (80 f). Body yellowish-reddish white, thorax and abdomen above with brownish arpiana. 
bands, the forewing with the same markings on the light ground, a line at the base, behind it a spot below 
the cell, then 3 interrupted, irregular lines and at the cell-end a darker spot from which an interrupted 
line extends to the inner margin; besides 4 postmedian lines and a fifth line close at the distal margin, in the 
lower half broken up into spots. Hindwing scantily scaled, white, in the abdominal half dusted with brownish. 
Abdomen brownish-black. Rio de Janeiro. 
T. alma Weymer ( = septemlinea Schs.) (80 e) entirely resembles arpiana , but the abdomen above alma. 
is white. The ground of the wings may be somewhat whiter. Sao Paulo. 
T. intercalaris sp. n. (80 f) forms a transition from the preceding species to the following mexicana. intercdlari 
Somewhat larger and more elongate. Forewing feebly iridescent reddish-white, the lines as in alma, but more 
sand-coloured brownish, less distinct; discal dot absent, the whole cell and the space between 5 and 6 as far 
as the distal margin almost hyaline. Hindwing whitish, smoky except a marginal band, the darkest in the 
abdominal half. Body whitish, head and collar brownish, thorax and abdomen with yellowish-brown bands. 
According to 1 $ from Espiritu Santo (Brazil). Type in the Coll. Wernicke, Dresden. 
T. mexicana H.-S. (= pluiilinea WTcr.) (80 f) is larger than the preceding species, similar, though mexicana 
with darker yellowish-brown markings, the transverse lines more or less distinct only in the marginal half and 
costally, in the basal % below the cell flown together into a large shadow. The cell and the space between 
5 and 6 as far as the subterminal line hyaline. The $ is very much larger, more densely scaled, darker 
fawn-coloured, the lines rather indistinct, the lightest is the subterminal line which gradually widens from 
the inner margin to 7 and narrows down again at the costal margin. Anal hair blackish. Mexico to Rio 
de Janeiro. 
T. rivulosa Btlr. (= butleri Berg) (80 f) resembles the preceding ones, forewing semidiaphanous rivulosa. 
whitish, on the veins with dark spots, with greyish-brown transverse markings: a small basal spot, before the 
centre with 2 angular bands, then a broad median band interrupted by the hyaline cell, behind it 3 parallel 
undulating lines, a light brown marginal band, and a series of dark brown marginal spots. Head and prothorax 
white, metathorax and abdomen brownish. Rio Negro (Colombia). 
T. opalina Wkr. ( = cervina Wkr.) (81 e). The $ resembles alma and intercalaris ; the narrow forewing opalina. 
at the distal margin dentate, whitish, iridescent, with 2 irregular, broad, reddish antemedian transverse bands 
and a broad postmedian band, in the latter with 4 whitish undulating lines and finely brown-striped veins 
between them, the small hindwings feebly yellowish. The $ is reddish yellowish-brown with 6 dentate darker 
transverse lines and an incompletely double whitish subterminal line, and a whitish discal spot between the 
3rd and 4th lines. Ega (Amazons). 
T. hirta Stoll (80 f). The $ is scantily scaled, very light yellowish-brown, with 3 broad darker transverse hirta. 
bands, the median band being the broadest, enclosing 2 black dots in the cell-angles, before the darker and 
lighter speckled fringes with a narrow darker marginal band. Guiana. The larva painted by Stoll looks dark 
brown with a white dorsal line and 2 yellow lateral lines, and fir-tree-like hairs, on the 1st ring with 4 longer 
ones, the 2 longest with a white ring. It lives on water-melon. I presume that the <$<$ described by Dognin 
as pallida (80 e) belong hereto. 
T. trilinea Dogn. (80 g) is somewhat more greyish-brown, the median band interrupted on 2. so trilinea. 
that the light border-lines of the ground-colour form an X here, otherwise very similarly marked as hirta. 
Ecuador (Loja); also from Leopoldina (Brazil).
