a broad orange band. Such a specimen (unfortunately no habitat stated, but probably from New Guinea) 
lying before me I have figured and denominate it owing to its quite different exterior: ab. palatinensis ab. nov. 
(51 g). — But there are also specimens without the yellow band of the hindwing on both sides, which were 
already mentioned by Pagenstecher from Amboina: ab. postnigra nom. nov. ■ —- Intermediary forms may 
be without the band above, but distinctly show it beneath. The fore wing varies to such an extent that it is 
difficult to find two quite equal specimens, and Pagenstecher mentions specimens in which this band is 
pierced by the blackish-brown ground-colour. —- Inab. gilolensis Pag., described from Halmaheira, the orange 
bands are on both wings more remote from the distal margin, and the band of the forewing ends obtuse in the 
centre of the costal margin. — Widely distributed in the Malayan Archipelago, from Celebes, Aru and New 
Guinea as well as the Key Islands across Waigeu, the Sula Islands, and the Moluccas. 
C. lata Pag. (51 g) is very much like the preceding species, but the orange bands are almost equally 
broad on all the 4 wings, ending obtuse on both sides, and the band of the forewing does not extend along the 
costal margin towards the base. Under surface like the upper, the orange slightly darker. Batjan, New Guinea, 
and Bismarck Archipelago. 
C. posticalis Guer. (= melaxantha Bsd.) (51 g as postica) is easily recognizable by the orange band 
of the forewing being reduced to a spot at the anal angle. The species varies in a similar way as the other species 
of Cleis ; the orange band of the hindwing may be entirely absent (— ab. aurantiaca Pag.), the spot of the forewing 
may be of the shape of a triangle (= ab. anan Pag.) or be otherwise different. Beneath the spot of the forewing 
may extend as a straight band to the costal margin, but it may also be of the shape and size as above; then 
sometimes a yellow cord from the base of the forewing may extend along the costa to the cell-end, where it 
breaks off. —- These aberrations, however, are not bound to geographical boundaries, and the names having 
at first been established as species were later on cancelled again as such by their author. Aru and Key Islands, 
Celebes, Bismarck Archipelago. 
C. atata Swh. On the forewing the yellow anal-angular spot extends to the distal margin and the 
costal stripe ends in the centre of the costal margin in a yellow spot below the costa. The yellow band of the 
hindwing is so broad that it almost covers half the wing. As the species flies in the Key Islands thus together 
with posticalis , it is, owing to the extraordinary variability of this species, not impossible that it is a form of 
that species. 
C. aureola Swh. from Obi is easily separable from atata by the forewing beneath showing a rather 
broad discal band, so that here the colouring approximates some specimens of evander. 
C. lunigera Btlr. (51 g). Forewing above with a large, obtusely triangular orange spot almost occupying 
the whole distal half of the wing; the hindwing above mostly with faint traces of a band only noticeable in 
the anal part, but beneath with a distinct distal band. Bismarck Archipelago. 
C. arctata Btlr. (= angustifascia Rob.) (51 h) from the Key Islands where it is very common, is 
at once to be recognized by the band of the forewing being much narrower towards the costa. The hindwing 
shows above and beneath a bright orange band. 
C. dichroa Bsd. (51 h). According to the short description (fitting several species), the $ of this species 
has an orange band on both wings, and romana having been formerly described by Pagenstecher is placed 
hereto by himself. The transverse band of the forewing has parallel margins and extends from the centre of 
the costa to the anal angle, whilst on the other hand the yellow of the band, particularly beneath extends towards 
the base along the costal margin. The <$ figured by Pagenstecher, however, corresponds rather little to this 
description, still less the species the $ of which (without a band of the hind wing) is placed hereto by Pagen¬ 
stecher and which we figure. It is impossible to ascertain anything accurate, as the type (according to Ober- 
thuer) is destroyed. Perhaps also propinqua Btlr. (= circumducta Pag.) belong hereto, and it is a very common 
and widely distributed species occurring in the Moluccas, the Aru-Islands, and New Guinea. If we do not regard 
(as Holland does) the latter names as synonyma of dichroa, propinqua could be maintained for specimens with 
particularly broad bands, in which the band of the hindwing may be continued yet for some distance at its 
proximal margin towards the base. 
C. aruana Btlr. (= arnana Swh.) (51 h). The band of the forewing reaches above neither to the 
costal margin nor to the proximal angle and represents a rather straight, in front stunted, behind rounded 
band. The very broad band of the hind wing extends to the anal angle, but it remains far remote from the apex 
and costal margin. Beneath the costal margin is orange proximally to the band which reaches to the costa. 
Aru Islands, Ceram, Goram. 
C. fasciata Btlr. Forewing with a narrow ($) or broader (§) oblique band which extends from the 
costal margin to behind the 2nd median vein and the proximal and distal edge of which is irregularly dentate, 
leaving free an apical third. Band of hindwing broad, its proximal edge somewhat indented; it extends from 
the anal angle to the costal margin, where it ends pointed. Ceram, Ternate, Halmaheira, Aru Islands. — This 
is probably merely an aberration, as the characteristic mark -— dentate edges of the bands — occurs in aberra¬ 
tions of very many species of Cleis. Amongst the numerous material of Cleis lying before me from Ternate, 
Aru, and Ceram, there is not one specimen exactly agreeing with Butler’s description.
