at the base and costal margin of the forewing. As according to examinations by Courvoisier the androconia ohsCUra - 
of the (Jc? of optimus are different from those of typical celeno, the relations of both forms to each other are 
not yet quite certain. —- sandya Fruhst. (151 c) shows also in the $ a rather broad marginal band of the forewing sandya.

observed in this island, by a very broad black distal part of the hindwing; conditions quite similar to those 
ascertained in Batjan-specimens of systematically remote species, such as in the Hesperid genus Tagiades

forms their origin is of course the best clue, for which reason we give a brief classification in the following table 
in order to facilitate the insertion of the collective specimens. 
India: alexis, conferenda 
Ceylon: tissama 
Andamans: tissama 
Nicobars: kinkurka 
Assam: elpinides 
Indo-China: agnata, conferenda 
Malacca: agnata 
Sumatra: agnata, alexis 
Nias: arama, zebrina 
Engano: eyria 
Borneo: zebra, levasa 
Natuna Islands: zebra 
Java: alexis, juliana, ruvana, parazebra, 
2 gennadia 
Lombok: juliana, ruvana 
Celebes: optimus, obscura, grisea 
Buru: sundara 
Banda: sundara 
Batjan: batjanensis 
Halmaheira: sandya, vuniya 
New Guinea: sundara 
Key Islands: sundara 
Aru Islands: Iucianus 
Bismarck Archipelago: evanescens 
Philippines: celeno, alexis 
Formosa: celeno, alexis 
South China: pur a. 
The larva of celeno is of the usual Lycaenid shape, woodlouse-shaped, thinly clad with fine fluffy hairs, 
on the sides of the dorsum with oblique diffuse spots. Spots olive-greenish. It attains a length of 1% cm and 
is covered with very fine, small, whitish tubercles. It lives on Heynea trigutta, Butea frondosa, but presumably 
also on other plants, such as Cardamomae. In India the larvae are closely guarded by the ants Camponotus mitis, 
until they change into the pale violettish-brown pupae of the usual shape. The imagines are very common in 
many districts, and like to settle down on damp places in the roads, but not so much on blossoms as the Jamides', 
they avoid vast sandy plains and agglomerations of boulders. 
L. vaneeckei Fruhst. (151 h) shows an extraordinary resemblance to the form tissama of celeno from vaneeckei. 
which it chiefly differs in the exterior by a more complicated marginal marking of the very light silvery blue 
wings above, but anatomically it is said to differ very much by showing most primitive clasping-organs. It 
was hitherto found only in Nias and in the collections it is presumably inserted amongst the celeno from there; 
it is the most common Lampides-io rnl in Nias. 
L. cleodus Fldr. (151 h) exhibits a great resemblance to celeno, particularly to its Indo-Chinese form cleodtis. 
pura (151 g), to which it may be better joined and with which it has also been united. The most conspicuous 
difference is the very delicate light blue above being so very transparent that the marking beneath shows very 
distinctly through. This under surface is so distinctly reproduced in our figure that the differences in the white 
undulations are at once visible. From Formosa and the Philippines to Sumatra and Nias. Moreover, the western¬ 
most specimens (from Sumatra) vary by exhibiting a deeper sky-blue colour above than specimens from the 
Philippines do, the latter having also been separated by Fruhstoreer as semperi from Mindoro, manias from semperi. 
Mindanao and potidolon from Bazilan; the latter name refers to a dry season form. -— trichonis Fruhst. (151 i) 
is the form from Palawan and North Borneo with a much plainer marking beneath. The neat, rather bright trichonis. 
marginal marking of the hindwing beneath of cleodus has here become a plain row of rings. -—- lydanus Fruhst. lydanus. 
(151 b), as the figure shows at once, is based upon a dry season form, the under surface of which is without
