from the west of Sumatra it has only been sent to me from Padang Pandjang from elevations of about 
600—800 m. — reinwardti Moore is even larger and the roundish black patches on both wings are of 
great size, about one third larger than in lynceus from Sumatra. Perak and other parts of the Malay 
Peninsula. — niasica Fruhst. on the other hand is a smaller race with the ground-colour more yellowish 
white instead of blue-black, which is particularly noticeable beneath, the wings more rounded, the black 
spots less developed, especially those in the cell of both wings. Nias, common. -—• favorinus subsp. nov. 
is the form which is called fumata at 74 b, and differs from Sumatran examples in the narrower wings 
and in having the ground-colour slightly inclined to grey-brown. The black patches smaller and especially 
those in the cell of the forewing more rounded. North Borneo, Kina Balu district and occurring at the 
west coast of Borneo southward to Pontianak. — fumata Fruhst., described from Amuntai and Banjermasin 
in South-East Borneo, deserves its name on account of having the upperside of both wings entirely suf¬ 
fused with dark smoke-brown, the underside being predominantly tinged with yellowish white instead of 
blue-white, as in favorinus. The dorsal part of the abdomen is likewise brown, instead of deep black, 
as in lyh'ceus and favorinus, the roundish patches of both wings above dull brown-black instead of deep 
black, as in Sumatra and North Borneo examples. — stolli Moore is inferior in size to all previously 
mentioned forms of lynceus and is of a lighter, grey-white colour throughout, which is a matter of course 
in a Javan butterfly, as all the species of this island, compared with their representatives from other 
districts, are distinguished by albinotic colouring, probably on account of the long dry season to which they 
are subjected. The black spots are analogous to those of favorinus, hut especially on the forewing charac¬ 
terized by a more pointed and wedge-shaped instead of rounded form. Cell-patch of the hindwing mostly 
very small, stolli is rare both in the east and west of Java, on the other hand it was easy to catch 
40—50 examples of the allied species logani in one morning. —- thalassica subsp. nov. inhabits the Natuna 
Islands; it even surpasses stolli in its light ground-colour, hut approximates closely in the arrangement of 
the markings to favorinus, with which it has also the size and wing-contour in common. 
H. logani only differs from lynceus in the lighter ground-colour and the reduced brown or blackish 
scaling on the upperside of the wings, also as a rule it is somewhat less spotted with black, the knob-like 
widening of the submarginal patches of the hindwing more delicate, removed further proximed, and the 
rounded dots at the submedian of the hindwing show a tendency to obsolescence, as well as the black 
bordering at the discocellular of the forewing. But these are trifling differences, and have led Niceville 
among others to accept lynceus and logani as merely forms of one species, between which no distinguishing 
line can be drawn. But nevertheless the valve shows characters of such decisive significance that the 
specific rank of logani cannot be questioned. The valve of logayii is scarcely half as broad as that of 
lynceus, dorsally with a concave excision for more than half of its extent, and with a projecting distal 
part which is sharply dentate, much more recalling that of d'urvillci from New Guinea than that of 
lynceus. logani is like lynceus a purely Macromalayan species, and there are the following races to record: 
logani Moore, from the Malay Peninsula, very large, grey-white, with stronger black patches than druryi 
Moore, which inhabits the alluvial plains of Sumatra and particularly in the west of the island is appar¬ 
ently much rarer than lynceus, with which it flies at the same time. This is only an unimportant modi¬ 
fication of the preceding, $ somewhat more yellowish than Perak $$ and with the black markings very 
slightly reduced. — donovani Moore, described from Singapore, is perhaps only a dry-season form and is 
based upon an example of small size. — diana Frulist., described from a $ from the Batu Islands, is still 
lighter and more transparent than druryi- $ from Sumatra. The black spots more reduced on both wings, 
the underside darker, the upperside on the contrary lighter grey. The cell of the forewing is traversed 
by 3 black longitudinal lines, which are separated basally, not forked. All the 3 lines connected hv a 
rounded transverse spot shortly before the apex of the cell. Cell of the hindwing with 2 longitudinal 
lines, of which the upper one is forked shortly before the end of the cell. The round spot in the cell 
and the 3 spots at the costal margin more reduced than in the allied races. It is interesting to observe 
that the Batu Islands produce the light logani, the neighbouring Nias on the contrary exclusively the dark 
lynceus. —- alcine Fruhst. (74 b), easily recognizable by the almost completely obsolescent black spots in 
the cell of the forewing and above the submedian of the hindwing, has beneath a dull yellowish silky 
gloss. Only known to me from Pontianak, where it occurs together with favorinus. In South-East Borneo 
occur $$ with alcine- pattern, but like fumata lightly suffused with smoke-brown. - — virgo Fruhst. is a race 
from northern Borneo with the general colouring more black-grey and the cell-spots somewhat stronger, 
but the knob-markings on the submarginal part of the hindwing reduced. —- alceste subsp. nov., an ex¬ 
tremely elegant light race from the Natuna Islands with entirely vitreous wings, without a trace of a 
yellowish or brownish tinge as in the local forms of the main island. — It is most nearly approached by 
the somewhat larger mevaria subsp. nov., which again shows very well-marked black spots on both wings, 
but less developed than those of lynceus stolli. mevaria on the other hand is much smaller than druryi 
from Sumatra and has not hitherto been noticed, since also the lynceus race from Java differs, as men¬ 
tioned above, from all the other lynceus forms by the whitish ground-colour being predominant. Not rare 
on Java and apparently on the whole the commonest Hestia of the island. Flies all the year round, but
