6. Genus: Xenoriua Prt. 
In the forewing the 2nd radial is forked, and rises before the 5th, the 3rd radial beyond the 5th. 1st 
cubitus separate, in the hindwing forked. 
X. cytheris Drc. (68 h). Forewing black, at the base with 2 yellow longitudinal stripes, a light yellow cytheris. 
discal spot and a similar subapical spot. Hindwing lighter yellow, with a black distal margin, hind-margin, 
and base. Tegulae and palpi yellow. Expanse about 30 mm. Mexico to Panama. — In australis Prt. (68 h) australis. 
from Brazil the central spot of the forewing is reduced, whilst in the form deleta Prt. it is entirely absent; the deleta. 
latter also occurs in Venezuela. 
X. ovata Dcjn. Similar to cytheris Drc. (68 h), but the forewing above lacks the subapical spot; palpi ovata. 
and tegulae black, not yellow as in cytheris. Colombia. 
X. pictifrons Warr. (68 h). Forewing similar to cytheris . all the veins broadly sulphur-coloured, pictifrons. 
Hindwing whitish, with a broad black distal margin which is narrowly continued at the costal margin as far 
as the base. Beneath the veins are very pale, a whitish stripe from the base at the costal margin and on the 
cubitus, increased to a large spot at the cell-end. In the hindwing the costal margin is also white. Expanse 
30 mm. South East Peru. 
X. grandimacula sp. n. (68 h) differs from cytheris in the forewing showing all the veins broadly grandxma- 
yellow and in the absence of the yellow - basal streaks, the discal spot being roundish as in reducta. Lower base 
with 2 hardly lighter vein-streaks, otherwise the veins are of the same colour. Hindwing yellow, distal margin 
broad black, base dusted with blackish. $ type from the Rio Songo in the Berlin Museum. 
X. biorbiculata Warr. (68 h). Forewing similar to pictifrons, veins yellowish with a hyaline white biorbicula- 
subapical spot which is crossed by 2 dark veins. Hindwing with a broad black costal margin and marginal 
band, the latter being half the width of the wing, base blackish; in contrast with the preceding species, the 
white area of the hindwing shows dark veins. Expanse: 28, $ 35 mm. Amazons. 
X. plataea Drc. (68 h). Blackish-brown forewings with a white triangular spot near the base on the plaiaea. 
hind-margin and an orange marginal spot between the 1st and 3rd median veins, hindwing white with a broad 
black distal margin and narrow hind-margin. Bolivia, Ecuador. 
X. exturbata sp. n. Similar to biorbiculata (68 h), the yellow discal spot being situate farther in exturbata. 
front, half in the cell and half behind it, all the markings are pale yellow, in the hindwing the axillaris and 
cubitus are blackish in the yellow discal area. Expanse 32 mm. Guatemala. $ type in the Berlin Museum. 
X. reducta sp. n. (68 h, i). Forewing as in exturbata, in the hindwing the abdominal margin is broadly reducta. 
black, so that only a yellow discal spot is left. Beneath as the preceding, below the costa a black basal streak. 
$ types from Bahia in the Berlin Museum. Distinguished from cytheris by the discal spot of the forewing 
being roundish and the yellow basal stripes being absent. 
7. Genus: OrScia Wkr. 
In the forewing the 2nd radial is forked and rises before the 5th, the 3rd beyond the 5th. 1st cubitus 
in the forewing separate, in the hindwing often forked. Palpi very long. 
0. truncata Wkr. (68 i). Body ochreous, abdomen above on the last segments with 2 posteriorly truncata. 
united black stripes. Forewing light grey, with a yellow, dark grey edged wedge from the base, beneath yellow 
with a grey marginal band proximally edged with dark grey, being broadest at the apex and not reaching to 
the tornus. Mexico to Guatemala. 
0. domina Schs. (68 i). Abdomen on the last segments dusted with black, the yellow wedge in the domina. 
$ bordered by the cubitus (in ^-specimens of truncata lying before me it extends beyond it), but distally extending 
farther beyond the cell, its distal margin not straight but distally convex. Expanse 34 mm. Costa Rica. 
0. homalochroa Fldr. ($ = damalis Schs.) (68 i). $ body and wings yellow, forewing with an olive- homalo- 
black, broad distal margin showing light yellow veins, whilst in the hindwing the distal margin is narrower, 
black and indented. The is similar, but the abdomen shows a black dorsal line on the 3rd segment and black 
dots on the following segments, separated by white segmental bands. Wings as in the $, the black distal 
margin of the hindwing beneath also parted by light lines. Expanse 38 mm. Costa Rica, Guatemala. 
0. prolifera Wkr. (= bifacies Wkr., nerias Fldr.) (68 i). Forewing with a black, white-dotted basal proliferc. 
area, an orange transverse band and black apical half with 2 white spots in it, hindwing orange, apex broadly, 
distal margin narrowly black. Amazons.
