a knowledge of the Rhopalocera of Australia, 7 
ing in discoidal cell, no black colouring on the lower half 
of disc, and the subcostal spots reduced to minute dots: 
expanse of wings 3 inches, 2 lines. 
? Somewhat like D. nerina ¢ , but without a trace of 
the tawny colouring above, with the white band of primaries 
and the broad central white patch of secondaries surrounded 
and tinted with brilliant purple instead of bluish-green; the 
squamose submarginal lunules pale brown; secondaries 
with the outer edge of the central patch dentate-sinuate 
as in D. Diomea; five discal white dots; wings below 
much more uniform than in D. nerina, submarginal 
lunulate spots whitish, becoming obsolete towards apex of 
primaries; the white band of secondaries much broader, 
dentate as above; the discal series of small spots smaller 
and whiter; primaries with only a tint of reddish on basal 
half of primaries, no tawny patch; only the external angle 
blackish; secondaries with no trace of the mahogany- 
colour on outer half of disc; costal spot semicircular, 
submarginal spots larger: expanse of wings 4 inches, 
4 lines. 
$, 2 Tasmania? Type, B. M. 
The above species was purchased at the sale of the 
Collection of the Entomological Society, and as it is 
certainly of the Australian type, and many of the Lepi- 
doptera then obtained were from Tasmania, I have little 
doubt but that the above locality is correct: there were 
certainly some N. Indian insects in the same lot, but the 
Indian type of Diadema is quite distinct from the Aus- 
tralian; besides which it is probable that if it were an 
Indian species Mr. Moore would have it in his Collection, 
which he certainly has not. 
Before leaving, for the present, the Australian Butterflies, 
I should like to say a word or two respecting the Catalogue 
prepared by Mr. Masters, and Mr. Miskin’s criticism of 
it in a paper read before the Entomological Society in 
1873. I need scarcely say that I do not agree with 
either author in rejecting the excellent arrangement. of 
the Suborder proposed by Mr. Bates in the Journal of 
Entomology; for 1 think, when they have seen and studied 
that paper (instead of ascribing the arrangement to our 
worthy friend Mr. Kirby), they will at once see that it is 
the only classification of the butterflies ever proposed which 
shows a clear perception of the affinities of the groups, 
or which reduces them to anything like a natural series.
