The races of 7. abeonw differ fvom each other in various degrees, a gradient 
between the forms being such as to bear a rather direct velatiouship with the 
widths of the gaps between their respective areas of distribution. T. a. helena 
being separated by nearly 600 miles from its ueighbour, 7’. a. rawnsleyi, is also 
one of the most distinetive of the fomns. 7. a. rawnsleyi and T. a. morrisi also are 
different in appearance and are very stable forms, oceupying separate areas. 
T. a. rawnsley? is melanic, T. ad. morrisi the most albinic of the races. South of 
the area veenpied by 7. w, morrisi is 7’. a joanna, This is most unstable as to 
wing pattern, no two examples being taken which are exactly alike. Waterhouse 
has shown the great probability that 7. @. joanna arose asa natural hybrid during 
recolonization of the Port Macquarie district by elements of two formerly 
separated subspecies, 7. a. morrisi and 7, a, aurelia. Ie suyported his deduetions 
by a series of hybridization experiments, and in the Fy-generation of morrisi x 
aurclia erosses, reprodueed the highly variable complex of forms typieal of the 
natural 7’, joanna population. 
Three southern races, 7. a, aurelia, T. a, abeona and VT, a. albifascia, are 
rather similar as to markings; their areas of distribution are close together and the 
transition from one race to the next is less clear ent than in more northern races, 
In the extreme south-east of the continent 7. a albifascia oceurs, chiefly along 
the eoast from Narooma to Wilson Promontory and extending westwards in 
pockets of favourable country as far as Mt, Macedon, Ferntree Gully and Lorne. 
The race is two-brooded, with a spring brood emerging in November and early 
December and an autumn one doring February and March. 
During a recent holiday visit to the south-east of South Australia it was of 
some interest to find a new race of Trsiphone abeona, allied te both 7’. a. albifascta 
and 7’. a. abeona, flying in a relatively restricted area of abont two square miles 
within the limits of the volcanic« crater lake basin, known as Lake Edward, This 
locality is over 200 miles west of the previously known western limit for the 
species, at Lorne, Victoria. Further collecting revealed the presence of the same 
form at Dartmoor on the Glenelg River, just over the border in western Victoria, 
but still leaving a belt. of country over 175 miles in width in which apparently it 
does not occur, Since this paper was prepared Dr. A. V. Southcott has given me 
a specimen from the Grampians, 
A formal deseription of the new race is as follows: 
TISIPIOND ABEONA ANTONI subsp, nov. 
Male. Wings above black; forewings with two blue-pupilled black eyespots 
each with a tiny white central dot; a broad orange band across midwing and 4 
narrower one near apex; the latter is distinctly wider and cream coloured near
