bright ruddle-red tinge and all the white spots are very small and equably distributed across the surface of 
the wings. It is much smaller than the preceding; A 39 — 40, $ 41—42 mm. Malacca and Sumatra. • — nileia nileia. 
Fruhst. (161 d as nila), from Borneo, differs from distanti in the AA above exhibiting lustrous green instead 
of blue streaks between the veins; the $$ exhibit beneath a larger, darker brown costal spot, and the small 
white and blue punctiform spots are more distinct; from the Kina Balu. 
I. aurigena Fruhst. is the only Iraota hitherto known from New Guinea. A above deep blue with a aurigena. 
narrow black distal margin. Beneath dark red-brown forewings with 3 sharply defined, browmish-red median 
bands and a brownish-red marginal band; before the latter light grey irroration. Hindwing before the margin 
likewise irrorated with grey, distal margin whitish, hind-margin vermilion. Both wings with conspicuous gold 
spots of a very bright gloss and a somewhat greenish reflection. German New Guinea. 
38. Genus: JHorsfieldia Filey (Amblypodia auct.). 
This genus is difficult to fix by the neuration, for which reason it is not universally acknowledged and 
considered to be more a so-called survey-group. Separated from the preceding by the much broader forewings 
—■ also in the A- Body less robust, costal margin of forewing already at the base strongly bent, hind-margin 
almost as long as costal margin, wdiereas in the A A of Iraota timoleon it is hardly 4 / 5 the length of it. Hinclwing 
also more circular, distal margin more uniformly bent. On the under surface most of the species distinctly 
show the protective colouring of a dry leaf the middle rib of which is imitated by an oblique streak from the 
apex of the forewing tq> the centre of the hind-margin of the hindwing. — The egg (of narada) is large,^covered 
with white, coarsely granulated, with a stopped-up hexagonal reticulation. The larva is of the usual woodlouse- 
shape of the Lycaenid larvae, being broad in the middle, with a small head and an obtuse anal joint; the seg¬ 
mental indentations are distinctly developed; on the sides of the body there are few small short bristles. Pupa 
uncommonly long and flat with a roundish top end, a centrally bossed thorax, and very slender pointed abdo¬ 
minal portion. — It appears to me not unlikely that all the forms known of Horsfieldia belong to a single 
species which is widely distributed and varies a great deal. — The genus was formerly called Amblypodia, but 
N. D. Riley proved that Horseield, the author of the name Amblypodia itself, has denoted his third group 
(apidanus- group) to be typical for the name Amblypodia, whereas ,,narada“ stands in the first place, being 
thus regarded as not typical by Horsfield himself. — This statement, indeed, abolishes a name having been 
used for almost 100 years. 
H. narada Hsf. (150 a). The species is easily recognised by the leaf-marking of the uniformly brown narada. 
under surface and the short stump of the tail on the hindwing. The northernmost form inhabiting the southern 
part of Continental India is dina Fruhst. ; it differs from the typical narada occurring in Java in the pale violet dina. 
upper surface of the A which exhibits a very large light red anal spot. Under surface yellowish-brown, basal 
half with groups of distantly separated dots. Not rare in the Nilgiris; also in the plains, near Metupalayan and 
as far as Madras, besides in Bombay and Assam. — taooana Mr. (A = arracana Sm.) differs from Javanese taooana . 
narada and from anita in its larger size; the upper surface shows a very bright lustrous blue, and the black 
marginal band is broad. Beneath both wings are violettish-ochreous, the transverse macular bands and the 
basal groups of spots are distinct, the stripe in the forewing is strongly bent. From Tenasserim. -— anita Hew. anita. 
(= narada Nic. nec Hsf., erichsoni IF. Alas, nec Fldr .) (148 a), from Siam, has the stripe of the forewing 
more parallel to the margin; its continuation on the hindwing is slightly undulate and in many Ao proximally 
bordered with a silvery grey. — andersoni Mr. is the form from the Mergui Archipelago (Sullivan Island), smaller andersoni. 
than taooana, both wings above ultra-marine, the black marginal band narrow; hindwing beneath quite similarly 
marked as in taooana, but of a darker shade. — fara Fruhst., from Sumatra, is larger, with rounder wings than fara. 
typical narada ; A °f a lighter and brighter blue; under surface like that of the preceding form, of a very dark 
Colouring, with prominent whitish-grey, band-like irroration before and behind the submarginal stripes of 
the hindwing. This Sumatran form varies according to the season; specimens from the dry season exhibit a 
violet reflection on the blue above, and beneath they are yellowish-grey, those of the rainy season, occurring 
also in alpine districts, are above more azure-blue, beneath brownish-violet; to the latter form also the Nias- 
specimens are reported to belong. •— salvia Fruhst., from North Borneo, has above a narrower marginal black salvia. 
part than fara, the blue of the upper surface is darker and more lustrous. Under surface blackish-grey, more 
monotonous than in fara. — orla Fruhst., from the Tengger Mts. in Java, being therefore a form of narada orla. 
narada , exhibits already a slight resemblance to Indian dina ; upper surface violettish-blue, with a narrow 
black distal margin. Under surface varying from yellowish-grey to reddish-grey, finely dotted black; taken at 
an altitude of about 2000 m. — naradoides Mr., from Ceylon, is likewise violet above, though with a broad naradoides. 
black margin; round the anal part of the hindwing and the small chestnut-brown tail some whitish irroration. 
Under surface violettish-brown, with blackish transverse bands and basal dots, the part round the base of the 
little tail in the A hrorated with whitish, in the $ tinged with orange. Another form of this Ceylon-race are
