formerly always caused by insufficient material. The white oval of the fore wing almost invariably dusted 
presbyter, with blackish or grey. Ceylou. -— presbyter Fruhst. The white discal spot of the forewing decidedly larger, 
without any black or grey dusting as exhibited in thwaitesi, and the under surface of both wings with more promi¬ 
nent brown spots and more abundantly grey than any of the vicarious forms. An excellent satellite island race. 
velina. Nicobar Islands; specimens from the Andamans are not before me. - — velina Fruhst. (154 d). Van Eecke 
writes that Sumatran malaya are above quite brown with a blurred spot and with fine markings beneath *). 
The under surface on the whole resembles the Javanese sister-race, whereas the upper surface is connected 
with sikkima Mr. All my specimens are smaller than the Indian, Formosa and Javanese specimens. North 
malaya. East Sumatra. Simalur. — malaya Horsf. (154 d) is undoubtedly the most magnificent race of the whole species. 
There exists no figure of it yet. The main characteristic consists of large white discs of the median zone 
of both wings. The $ thereby resembles the $$ of some Lycaenopsis, as for instance those of L. quadriplaga 
Snell., the East Javanese race of L. puspa Horsf. The East Javanese specimens of my collection are smaller 
than those from West Java. There seem also to exist temporal forms, of which those of the Monsoon period 
show still more extensive white areas and a more purely white under surface. East and West Java, Lombok, 
infumata. Bali, Flores, Sumbawa, Sumba. — infumata Fruhst. This insular race excels in size that from Sumatra, which 
it otherwise resembles most of all, but in the form of the dry period (being absent in Sumatra) the forewings 
are at least sometimes lighter, and in November specimens there may even be a white oval developed. The 
under surface is very much darkened, particularly the median zone of the forewing is more profusely speckled 
with brownish-grey than in any other form. It is extremely common in South Celebes, at elevations of up to 
1000 m; specimens from the northern parts of the island, which will surely differ from southern ones, are not 
rosanna. before me. South Celebes. — rosanna Fruhst. As to this interesting race, Semper writes that he received only 
2 specimens which he could not separate from malaya Horsf. from Java just like strongyle Fldr. from Amboina. 
This is a deplorable mistake, since the Philippine race combines the characters of the continental form by 
the (JcJ exhibiting above only a very faint whitish hue, whereas the 2$ somewhat approximate strong yle, 
without, however, not a whit coming up to the extensive, purely white oval of this race. The under surface 
differs both from continental and Malayan specimens by finer greyish-brown markings of the submarginal 
area of both wings and approximates, what appears to be very natural, voluhilis Fruhst. from Formosa. Luzon, 
strongyle. Mindanao, Mindoro. — strongyle Fldr. (154 d). Next to malaya the most spendid race, and above in both 
sexes easily discernible from the Javanese by the absence of the white discal spots of the hindwing. Beneath 
strongyloi- hardly different from Micromalayan specimens. Amboina, Burn, Obi, Key Tual, Aru. — strongyloides Fruhst. 
de.s. (154 c \) Habitus more imposing than that of the South Moluccan allies, above more intensely black with 
a very small discal spot slightly dusted with brownish on the veins. Beneath more extensively covered with 
nigra, a smoky brown than in any other race known to me. Halmaheira. -— nigra Misk. (154 d). A magnificent 
areal form approaching strongyle, from which it forms a transition to malaya by a relatively large white 
spot in the middle of the costal area of the hindwing. Beneath darker, more extensively lined smoky-brown 
than in Malayan specimens, but without attaining the intensity of the hue of strongyloides. nigra also ana¬ 
tomically differs somewhat from the more western races from Formosa and Java, which I examined for the 
sake of comparison, by a broader distal part of the valves which show sharper teeth. Cooldown, Cardwell, 
monacha. Cairns, Cape York. — monacha Sm. According to the description, with a narrower white area of the forewing 
than in strongyle, but with a distinct white area of the hindwing, thus most closely allied to the Australian 
orientalis. nigra Misk. Dutch New Guinea, Humboldt Bay. — orientalis J. u. T. (154 g), from the Schouten Island, 
Dutch New Guinea, approximates strongyle from which it deviates by a more roundish discal spot of the 
clcrica. forewing and the under surface being dusted darker. — clerica Fruhst. (154 d). $. Considerably smaller than 
Australian hindwing very faintly lighter whitish in the middle of the costal zone, the whitish oval of 
the forewing scarcely half as extensive as in nigra Misk. and slightly darkened greyish-brown. Kiriwina, 
Trobriancl Islands. 
10. Genus : I<ycaenopsts Fldr. (Cyaniris Dalm.) 
The genus Lycaenopsis, one of the most insignificant among the Indo Australian Lycaenids has never¬ 
theless been put to the most comprehensive monographical research by the epoch-making publication by 
T. A. Chapman **) in conjunction with the revision of the Lycaenid genus Lycaenopsis based upon morpho¬ 
logical comparisons of the clasping-organs by H. Fruhstorfer ***). In the latter work many anatomical 
and particularly geographical false conclusions of Chapman were cleared up and a number of Lycaenopsis newly
