of about 1000 m, as well as near Kuching in Sarawak, West Borneo. — camenae Nicev. (152 g) appears above camenae. 
somewhat darker blue than the Sumatran specimens, being magnificently brightened up in the disc, and the 
local differentiation is also noticeable in the clasping-organs, which are of a decidedly more robust structure, 
with a broad base of the uncus and longer extended valves than in the Borneo-form. Malayan Peninsula, 
still rare in the collections. —- elothales Frulnst. $ of a smaller habitus, the ground-colouring of a lighter blue, eloihales. 
the black distal border of the forewing, however, much broader, the whitish costal border of the hindwing 
less extensive, more indistinct than in coalita Nic. from Java. The submarginal black crescents of the hind¬ 
wing are absent, but in a supposed looking like de Niceville’s figure 13, they are again present. Sumatra; 
type from the Packing Boven District, also on the Battak Mountains. From Java we have no L. camenae ., 
but it was discovered in Flores, where an uncommonly altered insular race occurs: jugurtha Fruhst. It is con- juguriha. 
siderably smaller than the nomenclatural type with a dark and still intensely lustrous blue reminding us of 
L. cardia masinissa, and in some specimens with extensive, white costal embedments. This magnificently 
differentiated race occurs beside L. masinissa and L. limbatus epicharma Fruhst. All three have the same 
lustrous blue upper surface, being discernible only beneath and chiefly with certainty only by the genitals. 
Valeria Fruhst. $. Forewing with a black costal border, being much broader towards the apex, but tapering Valeria. 
off again in the median region and then extending in the same width to the anal angle. Cell-end with a 
distinct black crescent. The transcellular part white, the basal region with a light blue hue. Hindwing enti¬ 
rely light blue with a faint reflection and only 6 isolated black dots which are distally separated from a fine 
black antemarginal line by the purely white cilia. Beneath like in the from Sumatra. South Celebes, Bua 
Kraeng, at an altitude of 5000 ft, February 1896. 
L. strophis is one of the few species common to both Celebes and Borneo. The species will very 
probably be yet discovered in the Philippines, otherwise we would be forced to suppose them to have crossed 
over by way of Flores, unless we take strophis to be a relic from the time of the connexion of all the islands 
of to-day. — strophis Drc. (154 c). North Borneo, Sarawak, Perak. Only <$<$ are known. The species will strophis. 
undoubtedly be yet discovered in Sumatra and Java, having been probably overlooked owing to its resem¬ 
blance to other species, particularly to L. mnsina (152 h). Druce himself had little confidence in its being 
a distinct species and took it be to a doubtful temporal form of ceyx dilectissima (154 b). Chapman consi¬ 
dered strophis to be a local race of limbatus, and Fruhstorfer that of singalensis (recte cardia). The genital 
organs indeed place it near cardia, but by the spine branching off from the ventral side of the valve, they 
are easily discernible from cardia exhibiting a tooth rising dorsally. -— cynanae Fruhst. Lombok. 4000 ft., eynanac. 
April 1896. Smaller than specimens from Borneo, Perak and Celebes, above paler and beneath with neater 
punctiform spots. — euphon Fruhst. (152 g). differing from Macro- and Micromalayan cardia only by the euplwn. 
dark violet tint of the ground-colouring. $, however, very different: ground-colour lighter and more lustrous 
blue than in astarga- $ from Java, the black distal margin of the forewing almost twice as broad, hindwing 
with much more pregnant, antemarginal dots. Forewing with an extensive, subapical, white brightening. South 
Celebes, Bua Kraeng, 5000 ft., February 1896, collected by H. Fruhstorfer. 
L. ceyx. One of the neatest species and at the same time the species in which the genital organs are ceyx. 
the most primitively developed. The terminal part of the valve is but slightly chitinized, and according to 
how the preparation is placed, we are sometimes able to notice the beginning of an insignificant dental forma¬ 
tion. The presence of distal spines seems to be of a more frequent occurrence in the Borneo-race than in 
the Javanese name-type. By this small deviation Chapman was induced to separate the Javanese form (ceyx) 
by 6 numbers from the Borneo-race (dilectissima) . But whosoever observes the imagines, particularly also the 
and the joint habits (both are inhabitants of the mountains and do not occur at an elevation of less than 
1200 m) will not doubt as to their specific connexion. The shape of the valve, as has been already stated by Chap¬ 
man, resembles the most that of L. cossaeus plauta (154 b, c), and besides also that of L. moultoni Chapm., 
although not the least exterior affinity exists between these two species. Still much more interesting is the 
relation of L. ceyx to L. albocoeruleus Mr., for there is scarcely a doubt that the insular ceyx replaces the 
continental albocoeruleus in Java and Borneo, whereas albocoeruleus has even advanced as far as Sumatra. 
Another characteristic being of zoogeographical importance and at the same time mysterious, is the occurrence 
of a vicarious form which exists in Java beside ceyx and is found again in Celebes slightly modified, whereas 
in Celebes genuine ceyx have hitherto not yet been observed. Of ceyx we have, therefore, for the present 
only two certain insular races to register. — ceyx Nic. differs from the figured aristius Fruhst. $ (152 e) 
by the narrower black border of the forewing and the more prominent dotting of both wings beneath. The 
$, of which I captured two specimens on the Plateau of Pengalengan, is entirely white, with a verj' broad 
black costal and distal margin of the forewing, a series of relatively large black antemarginal dots of the 
hindwing likewise exhibiting an extensive costal margin. Bases of all the wings dark blue, the discal part 
of the forewing of a magnificent light blue reflection. Strange to say, it is precisely Java which has the
