December, 1952 THE SOUTH AUSTRALIAN NATURALIST 
gered, whereas in O. b. barnardi 
they tend to run in a virtually 
straight line with, at most, a single 
departure from regularity at about 
the middle of the length in the 
female. The silvery-white bars of 
the forewings below are much 
larger in the new race than in O. b. 
barnardi. In the female of the last 
named the dark patch at apex of 
cell on fore wing above extends to 
vein Cuia with a few traces only of 
purple scales between it and vein 
Ms, whereas in O. b. del phis 
female the dark patch does not go 
below vein Ms. In the single Brc- 
warrina female the purple extends 
to vein Mi. 
On the indications available the 
probable distribution of the race 
Ogyris b. barnardi is along the 
eastern side of the Great Dividing 
Range from Central Queensland 
south to Stradbroke Island. 
The race O. b. del phis ranges 
from New South Wales west of 
the Dividing Range to near the 
Head of Spencer Gulf in South 
Australia. 
The nymotypic race is taken 
in savannah woodland country 
which has a rainfall of between 20 
and 40 inches. It has been reported 
as feeding on a mistletoe parasitic 
upon wattles (Acacia). 
Annual rainfall in the areas 
where O. b. delphis has been taken 
lies between 10 and 15 inches; botli 
Why alia and Brewarrina lie on the 
southern and wetter fringe of the 
great mulga scrub formation of our 
arid central deserts. Since the 
mulga scrub areas extend across to 
Western Australia the species 
should be searched for also in parts 
of Western Australia, such as near 
the Murchison River and the 
Fraser Range, where occur similar 
environmental conditions. 
The present discovery adds an- 
other to the short but growing list 
of butterflies found to be living in 
the more arid portions of Australia. 
EXCURSION TO HENLEY 
SOUTH 
23rd August, 1952. 
Despite rough weather a small party of 
Naturalists spent an interesting afternoon 
amongst sandhills near West Beach. 
New records for the locality included 
the ornamental Castor Oil Plant, Ricinus 
communis L., and the ephemeral 
Perietaria debilis G. Forst. (under 
bushes), while a clump of some bulbous 
plant in the locality suggested Homeria 
collina Vent, but this requires confirma- 
tion. A solitary specimen of the Buck- 
thorn, Rhamnus alaternus L., was found 
in scrub there — the writer was interested 
to hear the name “Blowfly Tree” applied 
to this old hedge plant. Members of the 
party collected, in flower, specimens of 
Leucopogon parviflorus , Senecio lautus , 
Arclotis stoechadifolia and Acacia 
sophorae — the latter shrub dominated the 
more windswept dunes in the area.
