I. iridicolor Btlr. (10 f), from Sikkim (type) and Assam, is entirely unlike any other Indian species. 
Besides the distinctions from admirabilis already given, it may be noted that the median area is more variegated 
but the lines which bound it are much less pure white. 
39. Genus: Cflilororitlira Warr. 
Texture and coloration of wings somewhat as in Iotaphora, the wings broader, fore wing with less 
rounded apex, hindwing appreciably bent at 3rd radial, distal area much broader, with the markings macular, 
not linear. Hindtibia of <$ with a strong hair-pencil, which is wanting in Iotaphora. 
C. fea Btlr. (Vol. 4, pi. 1 g) was described from the Punjab but also inhabits the Khasis and has more 
recently been made known from Tse-kou, as subsp. missioniaria. Oberthur, who did not possess Indian ex¬ 
amples, supposed the Tibetan to be less grey, more yellow, but this is not borne out in his series of the latter. 
- There is, however, at Tse-kou a recurrent form (more than 50 per cent) in which the blackish apical patch 
of the hindwing beneath is wanting and this may be known as ab. missioniaria Oberth. The variation is possibly 
seasonal. 
40. Genus: Oloscore Warr. 
This genus, first published by Warren under the preoccupied name of Halterophora, differs from all 
the other genera in that the B frenulum terminates in a club. Otherwise it shows most of the characters of 
Hipparchus but is more specialised in venation, the 1st and the 3rd radial of the hindwing being shortly stalked 
with the adjacent veins. <$ antenna only pectinate in the proximal part. All the species are Papuan. 
i 
Section A. Hindwing not angled at 3rd radial. 
D. thalassias Warr. Similar to nereis (4 c) but much less sharply contrasted, the white parts being less 
pure and less extended, the green mostly less deep, more bluish. The oblique white line from apex of forewing 
is scarcely at all sinuous, and the green shade proximal to it is less dark, more yellow-green, much reduced, 
forming merely a thick line. Dutch New Guinea. Also from Aru. 
D. nereis Warr. (4 c). The $ is well represented in our figure and as the sexes are marked alike it 
needs no further elucidation. Described from the Arfak Mountains, known also from other ranges in Dutch 
and British New Guinea. 
D. ancyla Prout (lOf). A rather smaller species, with much less rounded hindwing and with simpler 
markings. The curved white line from the apex of the forewing is quite distinctive. Described from the 
Weyland Mountains, Dutch New Guinea. A $ from Tavarare, Owen Stanley Range, is in coll. L. B. Prout. 
D. melanomma Warr. (10 f) differs from all the other species in the lai’ge and elongate black-brown 
cell-spots. British and Dutch New Guinea, the type from Biagi. 
D. fulgurata Warr. (= meeki Warr.) ( 1 0 f) and the following species are distinguished by the zigzag 
and punctiform white lines and the very sharply white-spotted brown fringes. In fulgurata the hindwing ap¬ 
proaches the peculiar shape of that of ancyla. British and Dutch New Guinea. 
D. homoeotes Prout. Extremely like fulgurata (10 f), but with the distal margin of both wings more 
rounded, the antennal pectinations of the much shorter, ceasing at about the 24th joint (in fulgurata con¬ 
tinued to about the 36th). Dutch New Guinea, the type from the Arfak Mountains. 
Section B. Hindwing angled at 3rd radial. 
D. bicolor Warr. (4 b). Apart from the wing-form and the less zigzag lines, different from fulgurata 
in the enlarged cell-dots and the browner (not cream-whitish) crest at the base of the abdomen. Fergusson 
Island (loc. typ.), British and Dutch New Guinea. 
D. punctifimtoria Warr. (= mistifimbria Prout) (4 b). More slenderly built than bicolor, tail of hind¬ 
wing shorter, colour bluer green, cell-spots not brown (some blackish scales making them appear dark-green), 
fringes less chequered, on forewing almost plain green. British New Guinea (type from Upper Aroa River) 
and Dutch New Guinea. 
41 Genus: Ornitliospila Warr. 
Palpus long. Antenna many-jointed, in the d with slender pectinations. Hindtibia not dilated. Ab¬ 
domen not crested. Forewing with distal margin not angled; all the subcostals stalked, the 5th arising before 
the 2nd. Hindwing with discocellulars strongly angled. Colouring very vivid green, generally with red cell-
