very dentate cap, are unparallelled among all the Lycaenidae. And besides, by the dorsal and ventral processus 
being covered with uncommonly long bristles it even excels L. cossaea. The imagines resemble above about 
Bothrinia nebulosa Leech (Vol. I, t. 83 g), but the forewings are much more pointed, and the hindwing before 
the distal margin still lighter whitish than in Bothrinia chennelli, the spotting of the under surface almost iden¬ 
tical with that of L. camenae Nic. Snellen states the habitat to be at altitudes of 1500 to 1850 m in the 
Preanger. I myself collected 2 on the Plateau ef Pengalengan at an altitude of about 1200 m in April. The 
$ seems to be still unknown, for the supposed $ of cyanicornis reproduced by Piepers *) so much resembles 
the $$ of L. cardia astarga Fruhst. that I cannot believe it to belong indeed to the broadly margined cyanicornis. 
L. catreus. Described according to the specimens I discovered on the Plateau of Pengalengan in April 
1893. Both Butler and Chapman doubt whether this species belongs to the Lycaenopsis, and still catreus 
is an entirely typical species of the genus, and the might even be mistaken for the ^ of L. corythrus, L. coalita, 
or of L. albidisca. The $, however, is rather isolated by its abnormal heteromorphism and the colouring above 
strikingly resembling a Nyctemera. Also the genital organs are hightly specialized, but nevertheless we observe 
also here resemblances to continental and Papuan species. The tegumen exhibits an uncommonly broad, strongly 
chitinized uncus armed with short spikes, and besides it has a still more clumsy appearance by a ventral skinny 
appendage. The valve, however, with its long, slender shape and its sharp apex belongs to the neatest formations 
(joins, in the whole genus. —- gaius Fruhst. is larger, lighter and more brilliantly blue than West Javanese. The 
submarginal and discal spotting beneath is much more prominent than in catreus. A novelty for Sumatra! 
Padang-Boven District, North East Sumatra. The Sumatran form is more closely allied to the East Javanese 
catreus. form than to the name-type from West Java: catreus Nic. d'd' make the impression of a small L. coalita or 
somewhat darker L. cardia, the under surface resembles that of L. placida. From the volcanos in West Java. ■— 
hcrmcias. hermeias Fruhst. is easily distinguishable from the West Javanese race by the purely white, discal brightening 
of the forewing recalling L. albidisca Mr., as well as by a variably extensive white zone in the costal area of the 
hindwing. 
argioloides. L. argioloides Rothsch. is a peculiar, unpretentious species which by its dark blue above and the 
dull grey beneath indeed strikingly resembles a Nacaduba, and on the whole approximates L. cara Nic. (152 g) 
from Celebes particularly by the way how the bands are distributed beneath. In its exterior argioloides is thus 
not in the least allied to L. catreus. The clasping-organs, however, are so closely allied to it that we might be 
induced to consider argioloides to be a local race of catreus. The valve has a still longer and sharper point than 
catreus, and the uncus is elliptical in its upper part, similar as in the species of the cardia- group, the ventral 
appendage distinctly separated from it, basally very broad, outwardly extended into a pointed, chitinized, 
spined tip. Snow Mountains, Dutch New Guinea. The form is represented in great numbers in the Leyden 
Museum, one $ in my collection. 
idamis. L. idamis Fruhst. $ scarcely discernible from L. catreus in its size, the relatively narrow black bor¬ 
dering of the forewings and, to a certain degree, even in the distribution of a slight, white tinge on both wings 
above. The blue ground-colour, however, lighter, without any violet admixture and of a more intense lustre 
than in catreus. Marking beneath exactly like in catreus, but without the blackish tinge of the apical region 
of the forewing, and deviating on the hindwing chiefly by another discal series of black striae in idamis, which 
are absent in catreus. P on the whole most closely allied to the $ of L. marginata Nic., consequently predo¬ 
minantly white, with a broad black costal margin of the forewing and two black marginal bands of the hindwing. 
Bases of both wings dusted with a bluish grey. Clasping-organs quite isolated, tegumen very broad with an 
extremely short uncus. Shape of valves unparallelled in the genus Lycaenopsis, entirely analogous to that 
of Lampides kankena (151 a) and L. kondulana Fldr., i. e. fork-shaped, bipartite, the ventral lamella only with 
a small dorsal bar. West Sumatra 1 North East Sumatra, $$ in Coll. Fruhstorfer. 
cara. L. cara Nic. (152 g). $ above lustrous dark blue, $ similar to dark $$ of L. argiolus coelestina from 
India and also to such of L. musina (152 h). Clasping-organs with a bossy, short uncus very much rounded 
off, exhibiting a pointed ventral appendage. Valve again allied to those of the genus Lampides, distantly recalling 
the valve of Lampides elpis. Valve short, the lower lamella terminating into two strong points, exhibiting 
besides a dorsal, inwardly bent appendage. South Celebes, where I collected it on the Peak of Bonthain, in 
February 1896, at an altitude of about 1500 m, 
puspa. L. puspa. Next to L. argiolus and L. cardia the most widely distributed Lycaenopsis, being distri¬ 
buted in partly magnificently differentiated, geographical races from India to the Philippines and from the 
Andamans to the Key Islands. Although puspa has already advanced to Sula Besi, it has still nowheres reached 
the Northern Moluccas, and from the Southern Moluccas we only know it from Goram. From New Guinea 
the species has not yet been fully ascertained. As the most interesting phenomenon within the species we must
