LAMPIDES. By Dr. A. Seitz. 
broad black margin, but also a very broad white discal band proximally joined by the blue basal colouring and 
the broad blue costal band; in a proximal direction from the white band there is above no more black at all. 
sarsina. — sarsina Fruhst. resembles coelestis (142 b), but it differs by a more intense blue above, resembling much rather 
the deep Morpho- blue of a kankena-bochides or metallica than the soft, light-blue of coelestis-<$. The white discal 
band is broader than in allectus ; $ larger than that of coelestis (142 b) with a broader marginal black entirely 
sarmice. covering the blue distal margin of the white discal band. — sarmice Fruhst. from New Mecklenburg (type in 
the Museum of Basle) exhibits at the costal margin a broad black costal band instead of the basal blue of the - 
preceding forms. The marginal black of the $ hindwing is also very much widened so that the upper surface 
of the insect appears predominantly black, although the white discal band of the upper surface is of a purer 
paralectus. white and somewhat broader than in allectus. — paralectus Sm. from New Pomerania and the somewhat larger 
rlath. elath Fruhst. from New Hannover, of which I only know the <$ of paralectus , may have to be separated as distinct 
species owing to the complicated structure of the $ of paralectus which has an expanse of 38 mm and is of a 
magnificent azure-blue and very much like the form allectus. In the $ the only difference above is exhibited 
by the white discal band of the forewing being above more pointed. The forms of alenas are mostly, where 
they do not approach the boundaries of their range, rather common lepidoptera, but difficult to discover from 
among the very common Thysonotis flying there, too. 
cuchylas. L. euchylas Hbn. (= liylas Cr.). As long as the disintegration of the old genus Cupido (= Lycaena) 
into numerous, easily discernible genera has not yet been universally acknowledged, the older name hylas, since 
it has already been (twice) bestowed upon genuine Lycaena, is not to denote another Lampides, too. Typical 
euchylas occur in Ceram, Amboina and Saparua; a separate form was described from an altitude of _ 700 m in 
plumbeus. Central Ceram, plumbeus Rothsch., in which the charming soft blue above is replaced by a leaden grey. — um- 
umbriel. briel Fruhst. (151 i), from Waigiu, according to Oberthur also from Salawatti, resembles coelestis (142 b) in 
the male to an extraordinary extent; but the blue colour above is different, and a comparison of our figures 
shows how much more abundant and more complicated the white marking beneath in the costal region of the 
nriel. forewing and the marginal third of the hindwing is in umbriel. —■ ariel Fruhst. (= euchylas Stgr.) (151 i) from 
the Key Islands is much smaller, the <$ with a rather broad (2 mm) black distal margin, and especially on the 
aruensis. hindwing a narrower white band. —- aruensis Pag., from the Aru Islands, shows on the hindwing beneath in 
both sexes round the distally verdigris-coloured, dark dots of the anal region another very distinct oclireous 
colouring. The blue above in the $ is also more distinctly defined and the ground of the band remains purely 
phosis. white. •—- phosis Fruhst., from the Islands of Boon and Jobi, forms the transition from the Moluccan to the 
Papuan forms. The blue of the above is more greenish, $ with a broader marginal black than Moluccan speci- 
eclectus. mens show, which, however, is not so extensive as in New Guinea specimens. — The latter, eclectus Sm. (151 i), 
are above deeply coloured and distinctly marked, the $ with a purely white, rather uniform discal band of 
polyaernus. 5 mm width, which is only proximally bordered with dark bine, otherwise with blackish-brown. — polyaernus 
Fruhst., from Salawatti, is very much like umbriel (151 i) and perhaps identical with the form mentioned by 
OberthItr from the Island of Yule as ,,euchylas^ (Lepid. Ocean, p. 62). The <$ of polyaernus differs so little 
from umbriel-<$, that this statement by Oberthur is quite comprehensible; in the $, however, the black is 
so extensive that the white discal spot of the forewing is very much confined. The blue dusting in the cell is 
increased as well as the blue colouring behind the discal band of the hindwing. Also beneath the black is 
epilectus. increased and the white discal band narrowed. Types in the Leiden Museum. — In epilectus Sm. the white 
band of the forewing is very broad where it touches the proximal margin. On the liinclwing only the marginal 
third is blue with a proximally convex interior bordering, the whole rest of the hindwing is white except the 
most proximal base which appears dull blue. In the $ the white of the forewing is costally, the white of the 
hindwing anally margined with blue. Under surface like that of umbriel (151 i), but the discal band of the 
forewing is much more pointed, and the small light crescents in the dark part of the hindwing are nearly all 
hyphasis. blue instead of white. Described from the Island of Fergusson; also from Kiriwina. -— In hyphasis Fruhst. 
(152 a) the white discal band above is rather pointed, in the $ the veins crossing it of a blue lustre, on the hind¬ 
wing the distal margin of the discal band is in the proximally very convex; in the $ the band is on both 
corana. sides margined with blue. Dutch New Guinea. — corana Fruhst. (= hylas van Eecke ) (152 a) occupies more 
the central part of the island; the ? differs little from that of hyphasis , only by the shape of the discal band 
and the base of the hindwing above being chill light blue; but in the <§ the white band of the forewing above 
is almost entirely covered with blue. Beneath -—- especially on the hindwing — the white discal area is likewise 
very much confined by the marginal black being very extensive, corana flies at the same places (Ivloofbivak, 
Central New Guinea) and at the same time (February, March), so that also owing to the beginning anatomical 
differentiation of the genital organs the beginning process of a collateral and nascent new species is presumed. 
nemophila. L. nemophila Btlr. (151 i). This species was separated with the other species with a white-banded upper 
surface by the name of Pepliphorus as a separate genus. Above very much like euchylas, though much larger, 
the white discal band beneath very smoothly defined, at the margins very little shaded; the rest of the wings 
dark brown, the undulations and small cucullate spots somewhat lighter, but rather inconspicuous. British 
minor. New Guinea. Very closely allied to this form are minor Rothsch. from the Snow Mountains in New Guinea 
pseudeuchy- and probably also pseudeuchylas Strd. from the upper course of the Kaiserin Augusta River and Seba in Dutch 
las. New Guinea, where they presumably represent the nemophila. Type in the Zoological Museum of Berlin.
