EUXOA. By W. Warren. 
1. Genus: luiaxou Hbn. 
This is characterised by the protuberant frons, bearing typically a central crater-shaped prominence; 
the spines of the tibiae, especially of the foretibiae, are stout and well-developed. It is divisible into 5 sections: 
— in the first the antennae of the 3 are bipectinated to apex; in the second the apical third is serrate; in section 
three the segments of the antennae end in pedicellate fascicles of cilia, the apical third being serrate; in the 
fourth the segments end in tuberculate or serrate fascicles; and in the fifth the antennae are simply ciliated or 
pubescent. Type E. decora Hbn. — cf. Vol. 3, p. 23. 
Sect. II Antennae of $ bipectinate for 2 / 3 ! the pectinations moderate. 
arenivolans. E. arenivolans Btlr. (6 a). Forewing grey; the area below median and the space between outer and sub¬ 
marginal lines pale grey or conspicuously whitish; veins finely black; costa dark; a black brown streak below 
cell from base to vein 2, then forming blotches between the veins at base, the veins remaining pale; a short 
black streak above inner margin near base and a narrow streak from middle of inner margin to tornus; the lines 
obsolete; orbicular and reniform brown at centre, ringed with grey and edged with black; the orbicular small, 
produced externally, sometimes met by a tooth from inner side of reniform; the cell dark brown; subterminal 
line defined by the black brown terminal area beyond it, dentate to termen at veins 7, 4, 3, 2, and 1; hind¬ 
wing dark brown, paler towards base; fringe pale, interlined with dark. Maui and Kona, Hawaii. 
repanda. E. repanda Walk. (6 a). Forewing grey suffused with fuscous, especially in the median area, and some¬ 
times the terminal; the veins black, finely interlined with white; lines and stigmata as in radians, but the clavi¬ 
form smaller and less distinct; the inner line angled outwards cpiite to middle of inner margin below vein 1; the 
outer line clearer, especially below middle; subterminal pale, shaped as in radians, preceded by distinct wedge- 
shaped marks; hindwing dingy grey or whitish, with the veins fuscous, the apical area more broadly fuscous. 
Victoria, Australia, and Tasmania. 
infusa. E. infusa Bsd. (= cordata Walk.) (6 a). Forewing pale lilac grey with a brownish tinge; lines double, 
fairly distinct; the inner waved, angled inwards on veins; the outer concisely lunulate-dentate; subterminal 
line obscure, pale, dentate below, preceded and followed by darker shading, sometimes only the terminal area 
darker; all the stigmata with black outlines; claviform small, concolorous; the two upper pale with grey centres; 
a black streak from orbicular to reniform, projecting beyond reniform to outer line; hindwing white, the ter- 
dcnsata. minal border towards apex fuscous; veins and cellspot dark; in the ab. densata ab. nov. (6 a) the forewing is 
suffused with reddish fuscous; the hindwing is dirty luteous suffused with fuscous, with the veins dark, and 
the termen broadly fuscous brown. Australia, New South Wales and Victoria. Larva varying from pale olive 
green to dull black, with dark lateral stripes; feeding on grasses, trifolium, and other low herbage. 
radians. E. radians Guen. (= munda Walk., scapularis Feld.) (6 a) d- Forewing greyish white, suffused either 
partially or entirely with brownish fuscous, the costal half, even in the darker specimens, generally remaining 
pale, often with a pinkish ochreous tint before inner line in submedian interspace and beyond reniform stigma; 
veins finely black; the median conspicuously white; inner line double, blackish, edged inwardly with white, 
excurved below middle and strongly angled outwards below vein 1, the space before it on submedian fold 
pale; outer line lunulate-dentate, generally obscure and interrupted; subterminal pale, strongly dentate, pre¬ 
ceded by black wedge-shaped marks; the terminal area darker; claviform stigma long, black brown; the cell 
black brown; orbicular a flattened oval with grey centre and pale ring; the reniform blackish or brown with 
a small brown projection beyond it above vein 5; hindwing white, with the veins and termen brownish fuscous, 
more broadly towards apex; fringe white; inner margin pale brownish; $ always more suffused with dark than 
basinotata. the G; but in the ab. basinotata Walk. (= turbulenta Walk., injuncta Walk.) (6 a) the whole forewing of the 
suffusa. $ is dull blackish fuscous with the markings obscured; — in ab. suffusa ab. nov. (6 b), from Parkside, S. Australia, 
Maravill, Victoria, and Sherlock River and Roebourne, W. Australia, the terminal area and to a smaller ex¬ 
tent the inner margin of the forewing of the <$ is clouded with brownish fuscous, which obliterates the wedge- 
shaped marks and imparts a generally redder tone to the wing; most of these GS are slightly below the 
gri.seata. average in point of size; — on the other hand in ab. griseata ab. nov. (6b), also all <$$, from Roebourne, W. 
Australia, the wedge-shaped markings are clearly expressed on a pale grey ground, while the dark suffusion is 
restricted to patches between the veins; the terminal intervals are especially dark, those on the folds tending 
to form blotches; the claviform stigma is decidedly shorter and the white hindwing shows hardly any dark 
arida. terminal suffusion; — another form, quite separate, but a development of the last; — ab. arida ab. nov. 
(6 b), also a from Roebourne, has the ground-colour pale luteous washed with grey and pale brown, the stig¬ 
mata and terminal intervals grey brown instead of black, the patch before inner line in submedian interval 
pale ochreous, as well as two longitudinal streaks along each fold, from the orbicular and claviform stigmata
