The central scarlet spot of liindAving beneath is variable in size and shape, usually obscurely 
margined i^aler, and often connected by a paler stalk Avith the scarlet subterminal spots. These spots 
are variable in size and shape, sometimes circular and regular, and sometimes so extended toAvards the 
centre of the Aving as to occupy more than half of the black terminal areia. This butterfly rarely 
comes so far south as Sydney, but is abundant at Brisbane.

This is not seasonal form, but the northAvestern race of argenthonai to AA'liieh it bears the same 
relation that oestiva bears to mysis, ComiDared Avitb tyjrieal the margins are more intensely 
black; the postcellular spot of forewing beneath is not enclosed in the black apical area: the obscure 
subteiminal spots of liindAving aboA'e are merged in the black termen: the subterminal spots of hindwin^ 
beneath are smaller and more regular, and the central scarlet spot of hindwing beneath is smaller and 
not connected Avith the subterminal sjDots.
