Thirty-one 
A NEW BUTTERFLY OF THE GENUS OGYRIS 
(Lepidoptera Rhopalocera) FROM WHYALLA, S. AUST. 
By Norman B. T indale, B . Sc. 
SUMMARY 
A new race of Ogyris barnardi 
Miskin, named delphis , is described 
from Whyalla, South Australia, 
adding another to the short list of 
butterflies living in the arid regions 
of Australia. 
INTRODUCTION. 
Mr. F. Erasmus Wilson of Meh 
bourne recently sent me a series of 
five examples of an interesting new 
race of the rather rare Barnard’s 
Azure Butterfly ( Ogyris barnardi 
Miskin 1890). 
Existence of subspecific modifi- 
cations previously had not been 
noticed in this species, of which 
the type example was taken on the 
Dawson River in East Central 
Queensland some time prior to 
1890. It was later taken at Emerald, 
at Milmerran, and at Clermont, 
all places in the same general area 
of Queensland; it also occurs on 
Stradbroke Island, off Brisbane. 
There are specimens before me 
from Clermont dated 10th and 
24th September, 1922. 
A male and female taken at 
Brewarrina in Western New South 
Wales between 21st September and 
7th October, 1925, are also avail- 
able but these prove to be different 
and seem to be related to the form 
about to be described from 
Whyalla, South Australia. 
OGYRIS BARNARDI DELPHIS 
subsp. nov. 
Male. Wings above very dull 
purple, with relatively wide black 
outer margin, widest near apex of 
forewing; inner margin of hind- 
wing gray with scattered white 
scales; and a lev/ bright blue ones; 
forewings below grayish-black, 
broadly suffused with grayish- white 
scales at the base of cell, along 
costa, and on apical fourth of 
wing; five blue-tinged white trans- 
verse bars in cel!; a line of black 
bars separating dark basal from 
light apical, portion of wing at 
three-fourths; these show a sinuate 
arrangement; hindwings grayish- 
white with narrow black margined 
brown markings; ciliae alternately 
white with black scales, and black. 
Length of forewing 16 mm; ex- 
panse 34 mm. 
Female. Wings above dull bluish- 
purple with broad black margins; 
a particularly dark patch of scales 
on fore wing near costa at three- 
fourths, extending to vein M.; 
w r ings below similar to male, the 
outermost white bar on fore wing 
relatively large. Length of forewing 
17 mm; expanse 37 mm. 
Locality , South Australia: Why- 
alla, November 4, 1951, taken by 
Mr. E. T. Smith (Holotype, a 
male, and three paratype males in 
collection of F. E. Wilson; allotype 
1.19098 in South Australia Museum 
presented by F. E. Wilson). New 
South Wales: Brewarrina 21 Sept.- 
7 Oct. 1925, two paratypes, in 
South Australian Museum, 5 males 
2 females examined. 
The type pair were taken to- 
gether at Whyalla, in company 
with Ogyris hewitsoni meridionalis, 
flying near mistletoes growing on 
mulga {Acacia aneura). 
This race is small (males ex- 
panding 34-38 mm.) and distinctive
