6 Mr. A. G. Butler’s Contributions towards 
maries with discoidal area pale pearly blue, crossed by 
three black-edged orange bands; discal area crossed from 
costa to external angle by a broad diffused dark brown 
nebulous band, relieving the white band of upper surface ; 
ocelli as above, but sometimes dull and alw ays distinct; all 
the white spots as above; secondaries crossed towards base 
by several indistinct brownish or better defined orange 
lines; an oblique dark or reddish-brown sinuated band 
(sometimes represented by two parallel lines) from costa to 
anal angle; discal area at times somewhat dusky, a row of 
blackish dots, two of which are most frequently represented 
by large violet and black ocelli with orange irides; a sub- 
marginal series of brown inyerted lunules and a fine mar- 
ginal line: body cream-coloured: expanse of wings 2 inches, 
1 line. 
@ Larger than the male, both ocelli well defined on all 
the wings ; basal half of secondaries above black-brown ; 
marginal lines well marked; orange colouring below pro- 
nounced; a distinct, pale-ochraceous, forked marking 
towards base of secondaries: expanse 2 inches, 2 lines. 
N. Australia (£isey); Queensland (Whitely). B. M. 
This species, although nearly allied to J. Orithya, may 
always be distinguished by the much whiter outer border 
of secondaries ; the male also differs constantly in the obso- 
lete character of the lower ocellus of primaries, the almost 
entire absence of blue at external angle, and frequently in 
the absence of the upper ocellus of secondaries, both of the 
ocelli being also constantly smaller. 
Genus DIADEMA. 
Diadema constans, n. sp. 
$ Similar to D. nerina 6, from which it differs as fol- 
lows:—Primaries with outer margin paler; subapical white 
spot bifid, postcellular trifid white patch much ‘narrower ; 
a discal series of five white dots from the subapical spot 
to beyond the outer extremity of the postcellular patch; 
secondaries with the central quadrifid white patch narrower 
(sometimes entirely suffused with lilacine); five discal white 
dots; marginal area paler: wings below altogether more 
uniform in tint; the marginal and submarginal lunulate 
spots uniformly dull buff; the white bands narrower and - 
tinted with pink, that of secondaries edged with purplish 
internall is the discal series of dots uniformly small and 
white ; primaries with barely a trace of the reddish colour-
