976 TAJURIA. By Dr. A. Seitz. 
T. diaeus Hew. above like a T. longinus, but at once recognizable by the earth-grey under surface, 
where the postdiscal transverse stripe runs obliquely, not extending parallel to the margin, but approaching 
the latter posteriorly. The $ is also to be recognized at once, by showing white brightenings in the discal area 
of the fore wing and in the apical area of the hindwing. The typical form flies in India as far as the Sunda 
Archipelago, seems to be very widely distributed, but owing to its being very rare it has not yet been often 
captured. - In Java the species shows very broad wings and it is rather large, the white area of the hindwing 
in the $ particularly prominent. This southern form was described as dacia Drc. (156 d). - The larva lives 
on the leaves of Lantana and on Loranthus bicolor. 
T. donafana Nic. (156 Bb). This likewise small species has already in the $ above so much black that 
the blue colour is confined to scarcely x / 3 of the forewing (in the hindmarginal area) and to the centre of the 
hindwing. The under surface is ochreous honey-coloured, except the anal area of the hindwing without any 
marking. Burma, Malacca, Sumatra. — In bangueyana Fruhst., from the Isle of Banguey, the blue above is 
duller and still more confined than in specimens from Tenasserim. — elaja Fruhst. from Nias is beneath darker 
ochreous-yellow, the dark green spots in the anal region of the hindwing more than twice as large as on the 
Continent. The species seems to be rare everywhere. 
T. megistia Hew. (156 d) is at once recognisable by the entirely black forewing of the <J. The specimens 
from the Khasia Hills in Assam, where the form described first flies, have also quite black hindwings excepting 
the costal area which is lustrous sky-blue. Beneath megistia is uni-coloured chrome-yellow except the postmedian 
chain of small stripes and the marking in the anal angle of the hindwing; in the forewing often yet a nebu¬ 
lous stripe in the marginal area. - yajna Doh. is the form from the Kumaon District in the Himalaya, where 
it was taken near Garjaghat and Baghrihat; it differs from typical megistia in the darker, more fox-coloured or 
brownish-red under surface. The blue of the hindwing above goes farther than in megistia, though not so far 
as in thria Nic. (156 d) from Sumatra, where it occupies the whole hindwing. — In istroidea Nic., from Sikkim, 
also the greatest part of the hindwing above is black, but the blue covers yet a great part of the discal cell 
into which it only slightly penetrates at its upper margin in yajna. — The $$ of these forms are still rarer 
than the (Jo and but insufficiently known; above they are black, in the disc of the w ing large, blue, but rather 
lustreless colouring which is mostly also extended across the base of the wing. The form thria exhibits above 
exactly the colouring of M. surindra. but it has quite a different under surface. 
T. japyx Hew. (156 d. e) is confined to Celebes; the of this rare species is above black with lustrous 
dark blue spots in and below the cell of the forewing and in the hindwing. Under surface dingy white with a 
postmedian chain of streaks and a similar nebulous stripe in the marginal area. The typical specimens come 
from North Celebes (Toli-toli etc.). — Those from South Celebes, massicus Fruhst. (156 e) have above more 
violettish-blue than dark blue, and the under surface has a quite light grey ground-colour with somewhat more 
distinct transverse stripes. 
T. cyrillus Hew. (156 e). Likewise from Celebes. A very large species, the colouring above similar 
to that of a gigantic T. thria ( 156 d), but also the basal part of the fore wing is lustrous blue. — In the South 
Celebic form herculius Fruhst. from Bua Kraeng, taken in February, the blue above is more extensive, the under 
surface a little lighter than in cyrillus ; of herculius only the $ has been described. Rare. 
T. kiihni Rob. This species was described from the Isle of Bangkai. and seems to be there the represen¬ 
tative of the Celebic regulus Stgr. (165 e, f) from the Minahassa. kiihni is described to differ from the figured 
regulus in the greenish-yellow basal part beneath and seems to exhibit less blue above, the basal part of the 
cj forewing being occupied by greenish-blue broad rays. The $ (in the figure the (J) of regulus has also above 
the base of the small upper tail a yellowish-red crescent which is absent in the figure of kiihni (Iris I, pi. 9, 
fig. 12), whereas in the description it is mentioned; at any rate, in the much larger (42 to 52 mm against 37 to 
39 mm in kiihni) Celebic form the under surface, in contrast to the greenish-yellow kiihni. shows a bright bluish- 
green hue in the basal part. The species is apparently very rare. 
T. mamertina Hew. (156 f). Whilst the $ of this species is beneath very similar to certain forms of man- 
darina and jalindra, the colouring above is entirely different. Upper surface of a glaring blue, in the forewing 
with a slight violet reflection in the disc; all the wings are narrowly bordered with black. In the $ there are 
indistinct grey brightenings with a slight bluish-green reflection like clouds on the upper surface. Under surface 
in the <J dark brick-red (not hemochrome, as in Hewitson’s somewhat incorrect figure), in the $ bone-coloured, 
the marginal area powdered with brown and crossed by transverse bands. The (J varies little, in the $ the 
grey embedments are of a variable brightness. In Mindanao (taken in Dugang). 
T. jalajala Fldr. (156 f). Above similarly coloured as mamertina, but the blue colour is lighter, more 
silvery with a slight square spot at the cell-end of the forewing, and below the costa of the hindwing the 
scent-spot is absent. Under surface earth-coloured grey, with a lighter marginal area crossed by dark trans¬ 
verse lines or chains. Distributed in the Philippines and taken at all times of the year, as for instance near Anti-
