uildulata subsp. n. the white spot is at the costal margin itself broader, then somewhat narrower and likewise unduhdu. 
posteriorly club-shaped, the proximal border of the black border at the distal margin of the hindwing is undulate. 
Brazil, §-type from Blumenau in the Berlin Museum. 
T. bialbifera Warr. (69 c). Forewing blackish-brown, veins yellow; a broad white band extends from huninjera. 
the costal margin before the centre to the analis shortly before the tornus, a yellow subterminal spot on the 
2nd median. In the $ the band is shorter and narrower, strangulated on the anterior edge of the cell, 
and the subterminal spot is hardly visible. Hindwing white, hind-margin broadly, distal margin more narrowly 
black, in the centre still more narrowed. Beneath the hind-margin is white. Expanse 30 mm. Ecuador. 
T. cistrinoides Dgn. Forewing blackish-brown, veins yellowish; a white discal spot extends from the cixfrinoi- 
costa to the tornus and terminates already before the analis; a subapical spot is likewise white. Greatest ,,rs> ' 
part of hindwing white, black are only the apical region as far as below the 2nd median, the distal margin 
from the 1st cubitus to the tornus, and the feebly irrorated hind-margin. Expanse 26 mm. Colombia. 
T. creon Drc. Forewing brown, veins yellowish, a discal band as in erymas, but centrally strangu- crcou. 
lated so that 2 spots are formed. Subapical spot absent. Hindwing white, apex broadly black, the black 
border towards the tornus entirely narrowed down. Expanse 28 mm. Costa Rica. 
T. hale skis Drc. Forewing pale brown, clouded with a darker shade, veins pale yellow, a yellow- halefdus. 
ish-white spot at the cell-end, which often lacks the $. Hindwing white, in the $ the apex is white, in 
the $ the whole distal margin. Expanse 28 to 30 mm. Costa Rica. 
T, crypsispila Warr. (69 c). Forewing blackish-brown, veins finely yellow, an indistinct pale spot crypsispila. 
distally to the cross-vein. Hindwing white with a broad black apex and distal margin, in the centre of the 
latter narrower. Hind-margin dusted with blackish. Expanse 33 mm. Panama. 
T. cistrina Drc. Forewing brown, veins and a subapical spot yellow, a white transverse band from cistrina. 
about the centre of the costa; hindwing white, at the apex and distal margin broadly black. Expanse 38 mm. 
Ecuador. 
T. cletor Drc. Forewing as in cistrina, hindwing black. Expanse 32 mm. Ecuador. cletor. 
T. nasor Drc. Forewing brown with yellow veins and a yellowish subapical spot; a yellowish-white nasor. 
zigzag-band from the centre of the costa to the hind-margin. Hinclwing brownish-white, with a broad dark 
brown border, the hind-marign broadly dusted with brown. Expanse 45 mm. Colombia. 
T, albltumida Dgn. Forewing blackish-brown, veins yellow almost as far as the distal margin, a albitumida. 
transverse band beginning below' the centre of the costa, proximally bordered by the cross-vein, termi¬ 
nating on the 2nd cubitus or right behind it; a likewise white subterminal spot on the 2nd median, two 
white longitudinal streaks near the base in and behind the cell. Hindwing brown with a white central triangle 
the apex of which is situate between the two cubital branches near the distal margin, the hind-margin being 
sometimes white. Veins black, distally ending in yellow' dots which may also be absent. Veins beneath white, 
hindwing more extensively white. 34 to 38 mm. Ecuador, Colombia, Peru. A variable species. 
T. augustimacula Dgn. Forewdng brown with yellow veins, a white spot behind the cell between auyusti- 
the 3rd and 1st median, a similar streak near the base above the analis. Hindwing greyish-brown, with a macula. 
white cellular spot extending to about 2 3 of the wing, beneath another white spot near the base behind 
the cell. Expanse 44 mm. Colombia. 
T. thanatos sp. n. (69 c). Basal half of forewing white, but the base blackish-grey, distal half blackish- thanatos. 
grey with partly sulphur-coloured veins and an orange subapical spot. Hindwing white with a black distal mar¬ 
gin and a slightly blackish-dusted hind-margin. type from Cuzco in the Coll. Seitz. Expanse only 22 mm. 
T. demades Drc. Forewdng pale brown, veins lighter with 3 indistinct, darker blackish transverse demades. 
bands and 3 dingy white streaks near the apex. Hindwing pale brown, somewhat hyaline at the base. Ex¬ 
panse 32 to 38 mm. Guatemala, Panama. — This species differs from nigrifascia Her. in the transverse bands 
being blackish instead of brown, the discal band projects at the cross-vein towards the base, whilst in nigri¬ 
fascia it extends uniformly. 
T. albilinea Schs. Forewing dark brown, veins brownish-yellow, with a white median stripe which is albilinea. 
bent inwards at the 2nd cubitus and angular behind the analis. Before the distal margin a greyish-brown 
shadow. Hindwing thinly smoky-brownish, veins finely yellow, a yellow space below the cell from the base 
to before the centre. Expanse 39 mm. Costa Rica. 
T. maxima Drc. (63 c). Forewing brown, with a pale brownish transverse line across the cross-vein maxima. 
from the costal margin to the analis and a similar subterminal zigzag line. Veins light brown. Hindwing brown¬ 
ish-grey, turning hyaline towards the base. -—■ The form funiosa Warr. is dark olive-coloured, a yellow spot fumosa. 
being indistinct in the nomenclatural form at the base of the cell of the forewing, the centrally situated 
transverse line is absent. Panama.
