deposited in small heaps of 40 to 50 on the trunks of trees and apparently transported by ants to the food- 
plant, Acacia pycnantha. Both the larva and pupa are found in the nests of Iridomyrmex nitidus, ants by 
which they are most carefully attended to. A pupa, for instance, being exposed to the sun was at once covered 
with a small heap of dirt by the ants, in order to protect it against the heat and light. Also across the newly 
crept out imagines the ants run and climb without, however, doing them any harm. Flying from October 
till February, both sexes creeping out from the pupae almost in the same number. Environs of Sydney. 
P. eone, the nomenclatural type of which originates from the Aru Islands, only occurs very rarely. 
In the Key Islands it seems to be absent, but the species was recently discovered in Central Dutch New Guinea. 
The d is known to me only from Felder’s figure and somewhat recalls Hyfwlycaena, being above black and 
on the hindwing with a narrow blue submarginal band, which is besides accompanied by a neat white line before 
the distal margin. $ beneath whitish, in the whole exterior resembling species of the group of forms of Holochila. 
A black subanal wedge-shaped spot of the hindwing is situate in a light brown area. -— eone Fldr. (145 k) inhabits 
the northernmost part of Queensland from Cairns to Cape York. The specimens accessible to me differ but 
slightly from Felder’s figure of the Aru specimens. — iovis subsp. nov. (145 k) is a race of a larger habitus 
with a more extensive yellowish part on the hindwing above and a faded blackish marking beneath. Dutch 
New Guinea. 
P. brisbanensis Mish. is of a larger size than myrmecophila ; the $ with a broader brown marginal 
area of both wings. Marking beneath more distinctly black. Brisbane, Queensland. -— cyrilus And. & Spry 
is a smaller race of it from the environs of Sydney. 
P. fumidus Misk. is a distinctly separated species, the tails of the hindwings being more distinctly 
shaped than in the preceding species. Upper surface black with a metallic blue spot on the basal half of the 
forewing. Under surface silvery grey with dark brown spots. Distributed from Richmond River, New South 
Wales to Cairns in Queensland. 
P. digglesi Hew. is a magnificent species which by its intensely lustrous light blue upper surface 
may compete with the most beautiful Theclidae and Amblypodiae. Forewing with a somewhat broader margin, 
hindwing with a narrow black one. Under surface dull silvery grey, resembling Indo-Malayan Iolaus and Tajuria, 
with delicate blackish-grey bands and spots, as well as coppery subanal maculae of the hindwings. Range 
extending from Brisbane to Cairns in North Queensland. 
P. tualensis Rob. is an extremely rare species inhabiting both the Key Islands, where it visits the blos¬ 
soms of Leguminosae. As to its systematic position I am still in the dark, since the only specimen accessible 
to me does not permit of an examination. Neither did Niceville know where to place it, he thought of Holochila 
and found that the marking beneath somewhat recalls Zizera. From Pseudodipsas it differs by the absence 
of the tails, d above dark purple, $ uni-coloured dark brown. 
18. Genus : Usasi Nic. 
Orthomiella numbers among those monotypical ,,genera“ which from a rational point of view can be 
put aside. Its author de Niceville inserted it between the Azanus and Lycaenesthes, which proceeding is 
justified by the close relations of Orthomiella to the Lycaenesthes. It does, however, in no way harmonize with 
the Azanus, neither in the veins nor in the anatomy of the genitals. Bingham placed Orthomiella between 
Chilades and Niphanda which, in an anatomical way, do not show the least affinity to the Orthomiella. Swinhoe 
preferred to attach it to Azanus and Catochrysops, to which we must likewise make objections. The strangest 
fact, however, is that neither of the authors who were occupied with this ,,genus“ was struck bjr its close affinity 
to the ,,genus“ Una of which Orthomiella has the same total colouring, the arrangement of spots on the under 
surface, the veins and even the very peculiar shape of the uncommonly long palpi with dense bristly hair. Both 
Una and Orthomiella belong to those Lycaeninae that are without androconia, which is another though negative 
proof of the relations of the two groups of species. If it is yet stated here that the morphology of the clasping- 
organs has, in all the essential points, resulted in a complete harmony, it goes without saying that Orthomiella 
must be subordinated to Una which name had been published 75 pages before. Niceville, however, applied 
the ,,genus“ Una to the Pithecops and Neopithecops , a group of forms with which Una, except some subordinate 
marks in the veins, does not exhibit the least conformity, certainly still less than with the Zizera to which Distant 
joined Una usta which at that time was the only species known. Furthermore, the eyes of Orthomiella pontis 
are very long-haired, whereas the Una usta, which I examined, show bare eyes, in contrast with Niceville’s 
statements. I have already mentioned above in Tarucus (p. 992) that bare or bristly eyes by no means con- 
eone.
