Some of the females show a series of yellowish diseal spots on forewing beneath. In Australia this 
species is confined to the extremity of Cape York and is never abundant. We have a cluster of empty 
pupae cases attached to a broad mistletoe leaf: they closely resemble those of and show that the 
larvae are gregarious. 
Genus ELODINA Felder. 
Reise Novara Lepidoptera, i, i>. 216, 1865. 
Antennae about half the length of costa. Forewing with vein 11 from subcostal onefoiirtli before 
end of cell: vein 10 from vein 7 a little beyond end of cell: vein 9 and vein 8 absent: vein 6 from vein 
7 nearer to apex than to vein 10: vein 5 from cell very close to apex of cell. Hindwing with precostal 
spur: vein 0 sometimes slightly stalked wuth vein 7. Pujoa pointed at the head, but without dorsal or 
lateral spines. 
Type. Elodina egnatia Godart, from the Moluccas. 
Foodplant. Capparis, 
This genus is confined to the eastern portion of tlie Indo-Australian Region. All the species are 
variable, both geographically and seasonally, and in general appearance they resemble each other so 
closely that we have thouglit it needful to com])ile a key for the Australian species.

a. Forewing much narrower than in b. padim,

In angtdipennis ye'm 5 and A’ein 6 of fore.Aving arise from almost tlie same i)oint, while in pariliia 
these A'eiiis are dislincth' separate at base.

The bindwing beneath is very variable, sometimes being* nearly Avhite, and often much darker than 
in figure. Pseudomelanic examples sometimes occur: they do not sIioav extensions of the dark apical area, 
but patches of dark scales occur irregularly on the Avings. These patches niay appear upon both left and 
right Aving, but Avlien they do so they do not correspond in extent, shape or position: they occur both 
above and beneatli, but usually on the one surface only.
