spot ; two small spots near the apex and the hind-marginal border 
yellow-ochi’eous. Hindwing whitish, sulfused with yellow-ochi’eous 
near the costal margin, Avith the base and two transverse spots, 
one on the cell and one beyond it, dai’k brown ; near the hind- 
margin are two white-centred spots ; hind-margin broadly bordered 
with yellow-ochreous. 
At the time this specimen was captured Mr. Masters saw other, 
and, as he believes, similar buttex’liies, but as he was without a net 
he was unable to secure them. This Bombala example — for which 
I would suggest the varietal name P. suffusa — bears a remarkable 
resemblance in the markings of the upperside to a variety bred 
by Mr. J. A. Clark from a larva found on the banks of the 
River Lea, near London, which is figured in the ‘ Entomologist ’ 
for April, 1880. Like the specimen just described, this variety 
has the ordinary hind-marginal series of spots represented by 
small white dots. Now, it is well-known that the dominant 
Australian form of P. cardiU has the tlu’ee lower spots of this 
series centred with blue scales as pointed out by Prof. McCoy, 
who on this account suggested for it the name of P. Kershawi 
to distinguish it from the typical form in which these spots 
are black, but I believe it is not generally known that these 
blue spots are occasionally much obscui’ed in Australian specimens, 
and that cases have occurred in which European examples 
have these spots blue-centred. Such a specimen from the 
New Forest was exhibited at the meeting of the Entomo- 
logical Society in October, 1884, by i\Ir. Jenner Weir, who called 
attention to its similarity to the Australian form P. Kershawi:-^ 
I myself found a second specimen which possessed these blue- 
centred markings on the sand dunes near the “gates” of the 
Rhine, at Katwijk, in Holland, fluring the autumn of 1883. If 
the.se specimens had been caught in this country they woultl 
undoubtedly have been regarded as P. Kershawi, and passe<l 
without comment. In view of these facts, 1 think the conclusion 
is that no constant dilfex’eiice obtains between the Australian and
