LYCAENOPSIS. By H. FpvUhstorfer. 
hue of the hindwing. The species is to be reckoned among the many discoveries by Martin in North East 
Sumatra. The are not rare there, but of the $ scarcely another specimen will be found in European collections 
beside the type and one specimen of the Coll. Fruhstorfer. We may expect L. corythus to be discovered 
yet in the Malayan peninsula and perhaps even in Java. 
acesina. L. acesina B.-Bak. An interesting species resembles L. cam Nic. (152 g) in the markings beneath 
and differs from the other species from New Guinea by the band-like spotting beneath filled up with grey. 
Anatomically acesina represents the progressive extreme of the distal armature of the valves, the dorsal ter¬ 
minal tooth even excels considerably that of nedda in its strength and length. The spike-appendage of the 
uncus is likewise more robust than in nedda . and corythus. 
vuljanica. L. vul^pnica R. Upper surface of the only $ known violet, the costal and distal margins dull brown. 
On the hindwing the brown marginal band is analwards broken up into single spots. Under surface whitish- 
grey, forewing with a small discocellular stripe, a postmedian series of small streaks, and of small lunae flowing 
together to a postdiscal band, and an antemarginal row of minute spots, all of which are cinnamon-coloured. 
Hindwing with three basal dots, a median black spot and two small, discal, cinnamon-coloured stripes. Volcano 
Island near Kaiser Wilhelmsland. 
Group of species Notarthrinus Chapman. Uncus with apophysis lateralis. 
L. musina. As to its habitus and colouring the most insignificant of all the hycaenopsis, in the remar¬ 
kable structure of the chitinous armature, however, it excels even the species of the nedda-acesina-corythus- 
group. The uncus is peculiar for its likewise strongly chitinized apex which by its contours recalls 
that of L. albocoeruleus Mr., but exhibits yet Chapman’s ,,hooks“. The species has a larger range than 
was supposed hitherto. We find it in Macromalayana from where it has reached Burma and Annam, whilst 
musinoides. in the east it goes as far as Lombok. — musinoides Sivh. from Upper Burma. — pelides Fruhsi. $. Larger, much 
pelides. lighter than from Java and Borneo. The blue tint more intense, but lighter, the cell-end finely striated. 
South Annarn, Plateau of Lang-Bian, February, aboutl200 m. (H. Fruhstorfer leg.). Hereto probably 
candaules. also belong specimens mentioned by Bingham from Tenasserim. — candaules Nic. Perak, North East Sumatra. 
o beneath of a purer whitish-grey than Javanese <$<$ and those from Lombok, the small antemarginal spots 
more prominent. $ somewhat lighter than the musina musina -$ described by me from the Plateau of Penga- 
lengan. Beneath, however, darker grey. The form was recently also ascertained from Benkulen (West Sumatra) 
lugra. by van Eecice. — iugra Drc. (154 c). darker than Javanese ocL the markings beneath more prominent. 9 
described by me in 1909, smaller than the Javanese, with darker, almost quite blackish-grey hindwings. Cell-end 
of the forewing with a thicker longitudinal streak. According to Moulton on some days very common on 
the peak of Mount Matang, also on the Kinabalu, from where the type of Druce’s ,,species“ originated. —■ 
musina. musina Snell. (152 h). East and West Java, Lombok at an altitude of about 1200 m, in April. I found the $ 
having been unknown till 1909 on the Plateau of Pengalengan. It resembles somewhat the $ of coelestina and 
of astarga by the broad costal and distal margins of both wings, but it has a darker steel-blue reflection. The 
black antemarginal lunae of the hindwings are proximally bordered by a white undulate line. Piepers observed 
musina from an altitude of about 800 m in Central Java (Mount Ungaran) up to about 1800 m in the 
Preangers in West Java, the $ remained unknown also to him, and I myself only succeeded in capturing 
the one specimen figured on t. 152 h. 
L. quadriplaga. One of the most interesting species of the genus, the sexes being only slightly different, 
particularly in the Sumatran race. After having ascertained it to belong to the ,,Cyaniris“ in 1909, 1 was able 
in 1916 to prove the presence of the ,.hooks“ by illustrating the clasping-organs, with which it can be intro¬ 
duced as ,,N otarthrinus“ . The valve is remarkably broad and in its contours much more resembles that of 
Lampides elpis and Jamides bochus than a Lycaenopsis. The whole edge of the dorsal lamella is decorated 
with fine teeth. Uncus more clumsy, at the end more rounded off than that of L. musina Snell. This species 
has also a wider range than was supposed hitherto and will presumably prove to be a real Macromalayan, for 
lingga. it is only missing yet from the Malayan peninsula. — lingga Moult. According to its author’s figure and his 
diagnose of the only 2 originating from Mount Lingga in Sarawak, I do not doubt this ,,species“ to belong 
to quadriplaga. The 2 by a rather broad black distal margin of the hindwing even approaches the Javanese 
nearcha. form much more than the Sumatran nearcha. ■— nearcha Fruhst. (152 d). This magnificent form was among 
lb oo, 2 2$ in the Coll. Martin, g discernible from the Javanese race by a narrower black marginal area 
particularly on the hindwing, the white area above thereby increases in extent. The $ shows instead of a com¬ 
pact frame five almost isolated, black, antemarginal punctiform spots on the hindwing above. On the under 
surface the two sexes differ by the thick submarginal spots of the forewings in quadriplaga being reduced to 
quadripla- very fine striae. — quadriplaga Snell. (152 e) was at first observed by Dr. Piepers on the mountain-pass of 
ga.
