indications of white lines (bordering the ante- and postmedian) become conspicuous only at their costal end. 
Angabunga River and 1 $ from Biagi. 
X. interrufata Warr. (26 b), collected with the type series of monastics, is larger and more variegated, interrufata. 
with reddish-brown suffusions; the subordinate lines better expressed, notably just outside the postmedian, 
where a paler band is bounded by a dark line and bisected by another. Occurs also on Mount Goliath. 
X. cerasina Warr. (26 b). An elegant species, the pale parts almost entirely suffused with pink, the cerasina. 
dark brown basal patch and broad median band with a tinge of olive. Angabunga River and district. 
X. succerasina Prout, founded on a § from Mount Goliath, is perhaps another form of cerasina. Larger succerasina. 
(48 mm), less bright, the pink suffusion slighter, a subbasal band-like shade obliterating it till near the median 
band; this band more uniform in width, the antemedian less angulated. Hindwing with the dark ground-colour 
clouding the pink part (recalling interruptata).. A 2 from Mount Tafa, N. W. Ow r en Stanley Range, agrees es¬ 
sentially, though the subbasal band is less strongly developed and the antemedian line somewhat more dentate, 
thus slightly intermediate. 
X. lucirivata Warr. (26 b). Probably near monastica, but much more variegated. Forewing with basal ludrivata. 
patch and especially median band more definitely darkened; postmedian line running outward from costa to 
3rd radial; distal area with conspicuous macular pattern accompanying the subterminal. Hindwing with post¬ 
median strongly excurved in its central part; distal area paler, with macular subterminal markings. Upper 
Aroa River (type) and Biagi. - buntibasa form. nov. (26 b) will probably prove to be a separate race, or possibly buntibasa. 
even a species. Larger; forewing with antemedian line more direct, postmedian with its white accompanying 
line thickened anteriorly; hindwing with the central prominence of the postmedian less strong; both wings 
with distal area darkened, the subterminal and its spots almost obliterated. Buntibasa district, Kratke Mount¬ 
ains, 4000—5000 feet, July 1932 (F. Shaw Mayer), 1 $ in the Tring Museum. 
C. Section: antenna of ^ciliated, generally in fascicles which arise from 
teeth o r prominence s. 
X. percrassata Walk. (26 b). Readily recognizable by the sharply banded forewing with the markings percrassata. 
almost straight, including even the subterminal, which is bounded on both sides by complete dark shades; 
the median band usually consists of two stripes separated by a pale stripe, but occasionally forms a solid dark 
area. The type, from South Australia, is intermediate, the pale central part restricted to the region of the cell- 
dot. Tasmania to Brisbane. 
X. vacuaria Guen. (26 a) is more variable, but the shape of the median band (though not its breadth vacuaria. 
nor its intensity) is tolerably constant; for the differentiation of strumosata see below. The name-type is the 
“fulvous'’ form with very little marking in the distal area and somewhat recalls the ab. thedenii of the Palae- 
arctic quadrifasiata Cl. (Vol. 4, p. 226), though the basal patch is also dark. — ab. quartanata Guen. (= para- quartanata. 
delpha Lower ) (26 a) lacks the warm buff colouring and has a conspicuous, generally divided white band outside 
the median band and more or less strong dark shades bordering the subterminal. Intermediates are so rare that 
some authors have assumed that we were dealing with two species. Frequent in both forms from Tasmania 
(loc. typ.) to Victoria and in West Australia. Walker's Tasmanian “ solutata” belongs here and, through an 
error in labelling, must have misled Turner into an inaccurate synonymy; the 3 typical solutata (both sexes) 
are strumosata. 
X. imperviata Walk. (26 c) forms such an obvious link between vacuaria and strumosata that all three imperviata. 
must be referred to the same genus; perhaps a revision by the genitalia or other important characters will result 
in the transference of several other so-culled Eu'phyia of the Australian fauna. Much smaller than either vacuaria 
or strumosata (the $ here figured is one of the largest examples known to me), nearest to strumosata in appeararce; 
palpus less long (scarcely lj/o> as against almost 2), antennal teeth and ciliation of the $ intermediate towards 
those of vacuaria. The only further distinctions from strumosata, apart from size, seem to be the less sharply 
marked underside and the form of the median band, which is proximally more curved (but without the pro¬ 
nounced tooth at the fold) and throw's out tw r o longer teeth from its distal lobe, occasionally, though rarely, so 
long as to touch the first dark line of the distal area. South Australia (type from Adelaide) to New South Wales 
and West Australia. 
X. argodesma Meyr. (26 c). Antenna of somewhat dentate, with the ciliation nearly 1. Not unlike argodesma. 
some X. imperviata, palpus similar (Lower calls it 1. which is certainly an underestimate, while Meyrick’s 
“ 1%” errs in the opposite direction) and I shall not be surprised if the two supposed species are found to inter- 
grade. Characterized by the wdiite ground-colour, the veins tinged with pinkish brown, some pinkish suffusion 
at the proximal and distal sides respectively of the ante- and postmedian white bands, the termen more definitely
