UNKANA. By Dr. A. Seitz.

L. avesta Hew. (175 e as ,,aventa LC ). Forewing with but 2 spots, the spot in the cell being absent. 
Recognisable by the hindwing beneath, where a narrow, almost linear, bone-coloured band, which is pierced 
by the brown ground-colour shortly before the anal margin, separates the basal third from the rest of the 
wing; on the fore wing beneath another large bone-coloured rhombical spot in the centre of the costa and a 
lustrous silky brightening around the anal angle. From the Kina-Balu in Borneo; besides in Sumatra and 
Malacca. 
L. sarala Nic. (175 e) is allied to this species, but the band of the hindwing beneath is broader 
and also shows through a little above. As the species also penetrates into the palearctic parts of China, we 
have figured the upper surface in Vol. I, pi. 84 d, but Mabille has not mentioned it there in the text. 
It is also chiefly Indian, i. e. more common in the Indian region, and occurs in almost the whole of Indo- 
China. We therefore also figure the characteristic under surface in this volume. 
L. onara Btlr. (176 e, f) also exhibits a yellow' band on the hindwing beneath, but it is cpiite differently 
situate from that in the preceding species. It extends broad from the centre of the costa to the anal region, 
where it spreads entirely and even extends yet to the centre of the margin along the distal margin. Above 
the whole hindwing is yellow except the broad black costal margin. Typical onara originates from Java, where 
Fruhstorfer discovered it on the Volcano of Gedeh; similar specimens occur in Palawan (= excellens Stgr.), 
and in Sumatra (= adorabilis Fruhst.), where they exhibit a narrower yellow band of the hindwing, according 
to Dr. Martin’s statements. — According to Elwes, the species also occurs in Pulo-Laut, according to Frfhs- 
torfer in a separate subspecies which, however, is neither described nor denominated, onara seems to be 
everywhere rather rare. 
L. taprobanus Plotz (= mythecoides Nic.) (175f). This species has been often overlooked, neither 
Watson nor Elwes mentioning it, and Swinhoe does not quote it as Lotongus. This may be caused by the 
deceptive name, for ib does not live in Ceylon, as is stated below Plotz’s figure which is remarkably bad, 
but in Celebes. For this reason I figure both sexes which are beneath more similar than above. Characterised 
by a white median band on the hindwing beneath which is proximad sharply defined but distad hazy. — The 
type of Plotz’s figure is in the Munich Museum; it differs from all the specimens of my collection in two 
small spots being situate before the median band, whereas in the specimens before me there is always but one. 
L. my thee a Hew. (175 f) is similar to taprobanus , but in the disc of the forewing above there are 
only 3 small hyaline spots and no diminutive dots; the white band of the hindwing beneath is much larger, 
almost oval. Malacca. 
L. zeus Nic. (157 f). Only the <$ is before me, recognisable by a linear male stigma extending from 
the lower cell-angle almost to the centre of the inner margin of the forewing. A transverse hyaline spot in 
the cell, an upright one below the cell-end and a square spot beyond it, as well as a diminutive hyaline spot 
before the apical portion. Hindwing in the proximal portion covered with hair like a fleece. Described from 
Pulo-Laut; we figure a Philippinic specimen from Semrer’s collection. — In optimus Fruhst., from Assam 
(Khasia Hills), the spots in the disc are smaller and partly quite absent . The imago is rare. 
L. zenotl Nic. (171 f), from Pulo-Laut, is above monotonously brown with 2 small hyaline spots beyond 
the lower cell-end of the forewing; the short cell of the hindwing is entirely covered by a hair-pencil. Hindwing 
beneath brown, behind the cell-end somewhat lighter yellowish. 
61. Genus: ITnkaiia Dist. 
This genus contains a very large species as well as a form unknown to me, for which reason I cannot 
judge whether it is to be regarded as a separate species. The forewing exhibits 3 large white spots and a number 
of small ones before the apical region, the hindwing is in the $ disc very light, sometimes all white. The larva 
resembles those of the preceding genera, but the pupa is in front truncate and exhibits for the very long proboscis 
an extremely thin long cover projecting more than 1 cm beyond the abdominal end like a spear. 
U. attina Hew. (rf — batara Hist, nec Mr., anitta Plotz) (175 g). The forms of this species are 
hardly separable. Typical specimens occurring in Malacca, Sumatra, Java, and Borneo exhibit in the $ the 
white colour of the hindwing a little more reduced than in the figured $ of mindanaensis Fruhst. (175 g) from 
the Philippines. — In latreillei Fldr. (= cruda H.-Schdff.) the spots of the forewing are in the $ somewhat 
comma-shaped and the disc of the hindwing is slightly tinted yellowish; from Java. palawana Fruhst. is 
the form from Palawan, the of which differs in the dark smoky brown under surface with a very broad 
irregular median band. — Larva green, with lighter and darker transverse stripes, with a black head and 
black marking at the anal end. Pupa slender, in front without a frontal cone, pale bone-coloured, powdered 
with white, with a cover of the proboscis projecting long landwards. The larva lives on Pandanus fascicularis 
and species of Psychotria. in rolled leaves, The imago which becomes lively especially towards evening is mostly 
not common.
