darkest local form with the broadest black border, for the distal margin of the forewing is much more exten¬ 
sive than in dilectissima Die. and aristius Fruhst. The ceyx- $ deviates from the aristius- $ besides by the 
more extensive blue tinge on the bases of both wings, and the black margining of the forewing proceeds at 
the proximal margin much farther inward. West Java, on the Volcano Gede and the Plateau of Pengalengan 
at an altitude of more than 1200 m. Not uncommonly rare. Not observed by me in East Java. — dilec¬ 
tissima Die. (154 b). Hitherto only known from the Kina-Balu. 
L. apona Fruhst. Of this magnificent form only one $ is known, which was discovered at an alti¬ 
tude of about 2600 m on the peak of the Apo. in the midst of a vegetation of rhododendron and juniper. 
From Semper’s figure of the under surface we may infer that apona is the representative of the Macro- 
malayan L. ceyx and L. dilectissima. It is of a larger habitus, the submarginal clots more prominent than in 
ceyx and aristius, and there are small antemarginal and discal bands which are absent in the Macromalayan 
vicarious forms. Luzon. The discovery of further insular races in Mindoro, Mindanao and other Philippines 
with mountains of an altitude of about 2500 to 3000 m, is merely a matter of time, and I do not consider 
it to be impossible that apona will prove to be a local form of ceyx or aristius, if their clasping-organs will 
have been examined, just as it seems to me to be still very doubtful, whether L. aristius is a distinct 
species, in spite of the amazingly differentiated genital organs. 
L. aristius. Smaller, the contours of the wings rounder, forewings of the of a more intense, but 
still more lustrous blue than in ceyx. Hindwing with a more prominent black distal margin. forewing 
with a very broad black costal margin, expanding towards the apex to almost 4 mm of the upper surface 
and extending then into the anal angle. Forewing with a black cell-end, otherwise white. Hindwings white, 
with 6 antemarginal dots. Bases of all the wings slightly scaled grey and with a dull blue hue. L. aristius 
differs from L. ceyx-gtf chiefly by the broader black border of the forewing. In spite of the great difference 
in the spines of the valves, I treat aristius and aristinus as the forms of one species. — aristinus Fruhst. 
remarkably differs by the long spines of the valve from the vicarious form from Celebes. West Java, Pengalengan. 
aristius Fruhst. (152 e). South Celebes. I captured numbers of it on the Peak of Bonthain at an altitude 
of 5000 ft. in February 1896. The $ is somewhat smaller than the ^ of dilectissima, the black margin of the 
forewing broader. 
L. albocoeruleus, a magnificent species, above very much like L. marginata Nic., but larger and with 
rounder contours of the wings. It differs from L. ceyx by the extensive white discal spot of the forewing. 
albocoeruleus is found from Mussuri to Formosa, the Liukiu Islands and Japan, and in the south of Sumatra. 
They will certainly be sooner or later discovered in the Malayan Peninsula. The genital organs are highly 
specialized and interesting by the Sumatran local race being subject to a prolongation of the dorsal and 
ventral processus, so that both the uncus- and valval-apices of the Sumatran ovianus surpass in extent those 
of the continental vicarious form. The northernmost form of the collective species was found by Leech in 
May 1886 near Satsuma in Japan. Another form has been discovered by Pryer in the Liu-Kiu Islands and 
registered by Leech and Matsitmura, but there does not yet exist a description of these races. — amadis 
Fruhst. (vol. I, t. 83 h), from the mountains of West China, has already been very well figured (as albocoe¬ 
ruleus) in the palearctic part. sauteri Fruhst. Ground-colour darker, all the bands and spots more distinct 
than in Indian specimens. The clasping-organs almost identical with albocoeruleus . Formosa, February, April, 
very rare. Type in the Dahlem Entomological Museum. — albocoeruleus Mr. (152 f). From Mussori to Assam, 
everywhere very rare, occurring at altitudes from 1000 to about 2500 m, and according to the material of my 
collection, subject to the influence of the seasons. I believe that the <§ figured by Swinhoe, Lep. Inch VII, 
t. 625 as jynteana Nic. is decidedly a rainy period form of albocoeruleus. Doherty found the form in 
Bernardmyo in Upper Burma and in the Naga Hills. — ovianus Fruhst. <$ above differs from a- q of an extreme 
dry period form of L. albocoeruleus from Sikkim merely by a more distinctly defined white discal spot of the 
forewing, somewhat resembling in its extent that of L. marginata carna Nic. (152 cl). Hindwings almost enti¬ 
rely white, except a light blue basal hue. North East Sumatra. 
L. deliciosa Pagenstech. A magnificent species, deserving its name in every respect, above light blue, 
with a violet reflection. Forewing with a black subapical band separating a blue preapical spot from the middle 
of the wing. Hindwing with a large, submarginal crescent at the costal margin within a series of six prominent 
black marginal spots. From North Celebes, Minahassa. 
L. lanka Mr. According to Niceville preponderantly occurring in the mountains, for instance near 
Nuwara-Eliya and the Horton Plains, all the year round, sometimes in great swarms. It is not impossible 
that L. lanka represents only a mountainous form of L. eardia singalensis Fldr. The only <§ l was able to 
examine, only differs by a somewhat shorter valve, the terminal teeth of which are sharper and larger than 
in all the races and branches of eardia known to me. Their size is about between that of the terminal teeth 
of L. eardia astarga and of L. aristinus Fruhst. from Java. 
L. eardia. Not counting L. argiolus, the most widely distributed species occupying the whole range 
of the genus except the palearctic zone. The characters of the marking remain rather costant in the west of
