P. mindanensis Semp. (42 a, third figure, by mistake denoted as visaya). Head, palpi, collar, chest, mindanen- 
legs, and abdomen beneath yellowish-brown, abdomen above, forewing on both sides, antennae and dorsum Ws. 
blackish-grey, the forewing with a large, white discal spot dentiformly projecting once towards the base, twice 
towards the margin. Hindwing white with a broad, black margin and beneath besides with a natrow, black 
costal margin. Length of wings: 20, $ 18 mm. Flies near Eastern Mindanao in October. 
P. visaya Semp. (42 a, by mistake denoted as luzonensis ) is closely allied to P. mindanensis Semp., visaya. 
but the white spot is considerably smaller, and the veins of the basal half of the forewing are dusted grey; in 
the autumnal generation the black marginal band of the hindwing is broader than in the vernal. Length of 
wings: 14 to 15 mm. Flies in March, October and November in Cebu and Leyhe (Philippines). 
P. luzonensis Semp. (42 a, 5 th figure). Head, antennae and dorsal side blackish-grey, ventral side luzonensis. 
and palpi whitish-grey, legs yellowish, forewing black with a white discocellular spot. Hindwing white, with 
a black margin, beneath besides with a black proximal margin. Length of wings: 13 to 16 mm. Flies in 
April and May in Luzon. — In North East Luzon a form occurs, in which the black dusting of the hindwing 
is more extended, so that above only a discal area, beneath even only a large spot has remained, of the white 
ground-colour: ab. nigrosquamata ab. nov. nigrosqua- 
mata. 
P. lineosa Wkr. (— nubila Btlr.) (42 a). grey. Body and legs yellow. Forewing greyish-brown, lineosa. 
along the costal margin and distal margin brownish, with three black streaks at the yellowish base. The veins 
are whitish. Expanse of wings: 49 mm. Singapore, Malakka; Sumatra. 
P. simplex Leech. forewing whitish, along the veins and margins ochreous, behind the cell four simplex. 
brownish spots. Hindwing white, in the marginal area bestrewed with ochreous scales. Fringes hued ochreous 
with an ochreous line in front of them. Expanse of wings: 39 mm. Kanshirei. Formosa; in August. West 
China. — A somewhat lighter form occurring at the same place and deviating besides by the absence of the 
brownish spots behind the cell of the forewing, is monotonia ab. nov. monotonia. 
P. baswana Moore (41 g). white. Forewing in the apical third of the costal area brownish, in baswana. 
the posterior half of the marginal area with a narrower marginal band, in the basal area hued somewhat brownish, 
along the posterior margin of the cell a series of black spots. Hindwing with a brownish margin. Antennae 
light brown. Palpi ferrugnious reddish-yellow. Body beneath and legs yellowish-brown. Expanse of wings: 
37 mm. Java. 
P. semilucida Swinh. (= bicolor Wkr. nom. praeocc.) (42 a). <$-. body and legs brownish-yellow, semilucida- 
Forewing light brown, along the margin and at the apex somewhat darker, veins white, the second of the lower 
veins is almost four times as distant from the third as it is from the first vein, the third being as distant from 
the second as it is from the fourth. Hindwing white. Expanse of wings: 41 mm. Siam, Penang, Sarawak. 
As a doubtful Pantana we find Genusa^t destituta Wkr. (List Het. Br. Mus. 32, p. 341) (from Cambodja), destituta. 
mentioned in Kirby’s Catalogue: but the description seems to me to indicate (e. g.: ,,proboscis brevis“) that 
it is probably no Pantana (comp. t. 42, 2nd fig.). 
17. Genus: Wkr. 
Of this genus, as to the characterization of which we refer to Vol. II, p. 125, only very few species are 
known, one of which also penetrates the palearctic region. The genus is otherwise only distributed in North 
India as far as Formosa. 
P. apicalis Wkr. (41 g). Head and thorax light brown, palpi black with orange hair. Abdomen blackish, apicalis. 
with an orange anal brush. Forewing light brown, strewn with darker scales, being most densely accumulated 
on a transverse band bordering proximally on the large yellow apical spot. Hindwing light yellow, towards 
the dorsum with long brown hair. Under surface yellow. Expanse of wings: 64 mm. Sikkim (Darjeeling), 
Nepal, Silhet, Khasia Hills. 
P. decolorata Wkr. <$: whitish. Head and prothorax light doe-coloured. Abdomen above brown, decolorata. 
whitish at the base and beneath light ochreous at the apex. The anterior femora and tibiae with light ochreous 
hair. Forewing partly pale ochreous, thinly and very finely dusted black, and with a large, parted, light doe- 
coloured apical patch densely speckled with black. Hindwings uni-coloured. Expanse of wings: 82 mm. India: 
Benares, Khasia Hills, Darjeeling, Subathu.
