from Okinawa of the Liu-Kiu Islands. Judging from the figure of Fritze, weismanni is nearly allied to formo- 
sanus, but the yellow spot between the anterior and middle median of the forewings is absent and the sub¬ 
marginal lunae are considerably larger. 1 $ of the Coll. Plessen in Munich is far more than one third larger

basalis, only distally more extensively and brightly bordered in bluish-green. Island of Hainan, very rare. 
$ still unknown. 
E. nepenthes occurs exclusively in Indo-China being everywhere a rarity. Habitus of the C about 
the same as of the eudctmippus-C, though without the prominent black delimitation at the cell-end, and with 
smaller anteterminal spots of the forewings. The difference from eudamippus is to be noticed on the upper 
surface of the hindwings, varying according to the locality and showing, in the Tonkin-form not a complete 
black submarginal band, but only a double row of small black spots, the proximal series of which seems to be 
less prominent than the distal one. Two areal forms: nepenthes Sin., originally described from Siam, was first nepenthes.

smaller yellowish submarginal maculae of the forewings than nepenthes and a more abundant black bordering 
of the submarginal part of the under surface of the forewings than depicted by the author. On the hindwings 
the macular series are unequal, and sometimes the proximal row disappears, as for instance in the E of a dry 
period-form figured by Rothschild and Jordan in their C7mraxe<s-Monography. C of the rainy period-form¬ 
as I observed them near Chiem-Hoa in Central Tonkin, are recognizable by more prominent black markings 
of the upper surface of both the wings *). The $ discovered by myself is superior to the E in shape and dis¬ 
plays still more extensive black areas and spots on both the wings. Ed> of fugator were known already before 
my expedition to Tonkin. Oberthlr mentions already in 1893 specimens having been collected by Prince 
Henry of Orleans. 
E. dolon, an exclusively continental species, of which temporal forms are not known. Neither do we 
know anything about its early stages, nor about those of E. nepenthes and eudamippus. The under surface 
resembles that of jalysus, but the forewings have also yet a brown oblique band passing through beyond the 
cell from the costal margin to the hinder angle, dolon Wesiw. (Vol. I, p. 170, table 61 a) was described accor- dolon.

the forewings. The $ was discovered only in 1892 resembling the $ in every respect except that it has distally 
rounded tails like the $$ of E. eudamippus. It flies in April and May in the hot valleys occurring in but one 
generation, magniplagus Fruhst. (134 c) not rare on the Khasia-Hills in Assam. The cuneiform spots of the magnipla- 
forewings somewhat larger still than even in the Cashmir form, the black longitudinal band of the hindwings Q us - 
narrower than in Sikkim specimens and set with less developed, blue, minute lunae. Specimens of a dolon- 
form occurring in Tenasserim where the species was found in December and February, are absent in my collec¬ 
tion. Analogous to other butterflies from Birma and Tenasserim, as for instance also E. eudamippus, their 
habitus is probably less developed than dolon magniplagus , and they may exhibit a paler colouring. In the 
Shan States, however, we meet a luxuriant geographical race, grandis B. and J., distinguished by more .sharply grandis.

dolon, but it has a much broader black margin of the forewings and black submarginal band of the hindwings 
almost again as broad as that of the Indian races. The apex of the forewings is more pointed, the tails are 
much shorter than even in Sikkim-specimens. The submarginal spots of the forewings are roundish and distally 
not running to a point, growing very much smaller in the wing-centre, carolus thereby approximates grandis

wings. ^ with more extensive black marking and bordering of the wings than the E- Very rare. E from Siau-Lu

E. delphis, a predominantly Macromalayan species, advances to the north as far as Assam. — delphis del phis. 
Dbl., the name-type, originates from Silhet. E very similar to concha (134 c), but the subapical spot is, as a 
rule, more distinctly pronounced and the black apical margin of the forewings proxinrally more distinctly den¬ 
tate and decidedly narrower than in concha. The under surface distinguishable from that of delphis delphinion 
(134 c) only by somewhat finer blue discal lunular spots. A $ from Tenasserim deviates from the E only by the 
more imposing light ochre-yellow submarginal band of the under surface of the hindwings. It seems to fly all 
the year through, although the butterflies are always rare. Specimens which I collected near Bangkok in 
the dry period, are smaller than those from Tenasserim and exhibit above a darker greenish lustre. Pavie 
also observed delphis near Bangkok. -— concha Void. (134 c) which I have at hand in numbers from West concha. 
Sumatra, the surroundings of Padang Pandjang, considerably excels in size all the vicarious types. Apical 
macula of the forewings either very small or absent. The posterior submarginal lunae of the upper surface 
*) In specimens from Canton where fugator was recently found, the darkening of the upper and under surfaces is 
still more pronounced.
