Sc. fulviceps Fldr. (= caresa Drc.) (68 1). Head and palpi orange, wings blackish-brown, forewing fulviceps. 
with 3 white spots, hindwing with a white central area. ■— In quadripuncta Warr. on the forewing the spot quadripunc- 
distally to the cell is divided into two. Amazons, Ecuador. —- In abstracta Prt. the two proximal spots of the ahs{rnc{a ia " 
forewing are absent, only the distal one being present; in the hindwing the veins and central spot are partly 
black. British Guiana, also from Manaos. 
Sc. distinguenda Prt. is larger than fulviceps, expanse 35 to 36 mm, and dark brown instead of black, distinguen- 
Spots as in fulviceps. In the hindwing a hyaline white spot round the posterior half of the cross-vein, otherwise 
blackish-brown, beneath extended to the base. Upper Amazon River. 
Sc. fusciceps Warr. Forewing black, veins paler, a whitish spot on the bifurcation of the 3rd median fusciceps. 
and 1st cubitus. Hindwing black, with a whitish central spot from the base to % of the wing; posterior edge 
of cell, 2nd cubitus and bifurcation of 3rd median and 1st cubitus black. Beneath paler black, the light 
areas more extensive and with a bluish tinge. Head and thorax black (thereby distinguished from abstracta). 
—• In obstructa Warr. the white spot on the forewing above is absent, the white area of the hindwing is broader, obstructa. 
occupying the whole cell. Expanse 30 mm. Upper Amazon River. 
Sc. delifieata Dgn. Palpi black with yellow base, frons and antennae black, antennae basally yellow; delineata. 
vertex black, partly yellow, body otherwise grey. Forewing whitish-grey with black transverse lines: one basally 
from the costal margin to the analis; a broader one before the centre, slantingly directly distally as far as the 
cubitus, then narrowing down again proximally to the hind-margin; a postmedian one being straight and parallel 
to the margin as far as the 1st cubitus, behind it very much distally bent; a broader subterminal one, connected 
at the apex with the blackish distal margin. Hindwing above and both wings beneath pale blackish-grey. In 
the $ these markings are more indistinct. Expanse 26 to 30 mm. ETpper Amazon River. 
14. Gattung: TitSeraiistes Drc. 
Forewing: the 2nd radial forked before the 5th before the 3rd and 4th radials, the 3rd median and 
1st cubitus forked, discoidal cell y 2 of the wing or a little less, femora not densely haired, antennae in the d 
combed, wings thinly scaled. 
T. chloris Drc. (69 a). Forewing black, a hyaline basal streak to the cell-end, beyond the centre clitoris. 
of the wing two hyaline bands, neither of which reaches the margin of the wing. Hindwing whitish hyaline, 
apex, distal margin and hind-margin broad black, beneath the hind-margin is broad whitish-grey. Body black, 
abdomen beneath white. Ecuador, Bolivia. 
T. subalbata Dgn. (69 a). Forewing black with a whitish-hyaline basal line, a transverse band of subalbata. 
4 similar spots, in the direction of the tornus, and 3 small subapical spots which are almost parallel to the discal 
spots. Hindwing black, about two thirds of costal margin white, a whitish central area covered with minute 
black hairs, of the same colour is the hind-margin. Forewing beneath with white costal margin and veins at 
the base, hindwing beneath quite bluish-white; only the cross-vein black, the last third of the costal margin, 
the apex and distal margin as far as the analis the same. Expanse 24 mm. Bolivia. It may be only a form of 
the preceding. 
T. salvini Fldr. (= noctiluces Btlr.) (69 a). Forewing black with two whitish basal streaks, 2 discal salvini. 
spots and 1 submarginal spot below the apex. Hindwing black with a whitish, distally expanded central area. 
Tegulae ochreous. Panama, Costa Rica. 
T. eteocles Drc. Forewing dark brown, clouded with black, and on the distal margin below the apex eteocles. 
shaded with white, veins pale brown, a large round white spot at the cell-end, a small one close at the tornus, 
a narrow hyaline basal streak almost to the centre. Hindwing black with a broad hyaline central area. Body 
dark, tegulae orange. Expanse 37 mm. Guatemala, Nicaragua. 
I T. butes Drc. (= basalis Warr.). Forewing black with a whitish basal streak as far as the centre, butes. 
a whitish-hyaline transverse band from the costa to the tornus which it does not reach. Hindwing black with 
a hyaline central spot. Tegulae orange. Expanse 32 mm. Guatemala, Honduras. 
T. longipennis Schs. (69 b). Large species with narrow wings. Forewing black with a hyaline basal longipennis. 
streak as far as before the 2nd cubitus, a similar spot distally to the cross-vein, another one before the tornus, 
a similar submarginal spot below the apex. Hindwing blackish-brown, a basal streak behind the cell, and 
a spot distally to the cross-vein hyaline. Tegulae orange. Panama, Costa Rica. 
T. seminigrata Warr. (69 a). Forewing greyish-brown, a broad basal streak as far as the centre of seminigrata. 
the wing, a spot behind the cross-vein, and three submarginal spots whitish-hyaline, one of which is between 
the 1st and 2nd cubitus, the others on the 2nd and 1st medians. Hindwing whitish hyaline, costa, distal 
margin and hind-margin, veins and cross-vein black. Expanse 34 mm. Panama and Costa Rica.
