256 XANTHORHOE. By L. B. Prout. 
Tasmania and perhaps West Australia; further known from Lord Howe and Norfolk Islands and eastern New 
Guinea. 
subidaria. X. subidaria Guen. (= regulata Walk., $ = ? multifilaria Walk., gelidata Walk., algidata Walk., M. S., 
Turn.) (25 i). Antennal pectinations in long. Common and extremely variable, so that, even after the eli¬ 
mination of sodaliata, it has still an extensive synonymy. Palpus fully twice diameter of eye; pectinations long. 
relictata. G uenee’s type form has the median band of the forewing dark or blackish, solid. — ^-ab. relictata Walk. 
( = acutata Walk.) has a pale (in the subaberration acutata white) patch surrounding the cell-dot of the fore- 
cymaria, wing. Both the types, together with that of regulata, came from Sydney. — ab. (?) cymaria Guen. It is not 
quite clear on what grounds Guenee separated this from subidaria, as he makes it a species and does not even 
compare the two. A nearly typical subidaria $ in his collection is labelled “cymariaV’, but I gather that its 
median band should be “a little paler in the middle” and that therefore it may have to supplant ab. relictata 
or even ab. irrepleta ; it may, however, represent the usual $ form of subidaria (which was founded on 6 odd, 
permissata. generally distinguishable by its broader median band and darker hindwing. — $-ab. permissata Walk. has the 
brown parts suffused with dull red, the outer lobe of the median band rather acute, the white band beyond 
irrepleta. it strong. Type from Sydney. — ab. irrepleta nov. is a frequently recurring aberration with the median 
band ill developed, expressed chiefly by some dark shading on the antemedian and postmedian groups of lines 
and even this shading, in the <$, almost confined to the anterior half, blackest about the median and 3rd radial 
veins. This rather strongly recalls the commonest form of rosearia except in its less curved antemedian and 
less rosy-tinged underside. — subidaria is common and widely distributed in Australia, except the more tropical 
parts. 
epia. X. epia Turn. (25 i). and $, 29 to 34 mm. Palpus 3. Pectinations in 6. Forewing with apex pointed, 
termen bowed, oblique; grey, with numerous fine oblique fuscous lines, more or less reddish tinged; a small 
basal patch and a median band darker, the latter moderately broad anteriorly, from middle to hindmargin 
narrowing to % the breadth, proximal edge slightly curved, distal very obtusely exangulated in middle. Hind¬ 
wing rounded, grey, posteriorly with commencements of alternately darker and paler lines. Mt. Kosciusko 
5000 feet. Nearest centroneura (25 i) but much less pale, with less contrasted band and without the blackish 
vein-dots. 
centroneura. X. centroneura Meyr. (25 i). Palpus a little over twice diameter of eye. Pectinations at least as long 
as in epia. For the differentiation see above. Median band in general little darkened except on its edges, which 
show some red or dark markings; characteristic are the blackish vein-dots of the forewing, particularly outside 
the median band. Described from Mount Wellington, Tasmania; perhaps confined to that island. 
bituminea. X. bituminea Turn. Described from 2 9$ from Rosebery, Queensland, of which Turner says: “though 
the <3 is unknown, I think this species is allied to centroneura and epia". 30 mm. Forewing with costa nearly 
straight to near apex, apex acute, termen sinuate, oblique; fuscous, obscurely marked with slender wavy darker 
lines; median band hardly darker, defined distally by a very slight whitish line from 5 / 6 costa to 4 / 5 hindmargin. 
Hindwing with termen crenulate, only slightly rounded; grey, with the beginnings of obscure slender lines 
from abdominal margin. Underside fuscous, the hindwing better marked, with blackish cell-dot and 3 dark 
lines distally thereto. The second specimen is a well-marked aberration, the forewing with brown ante- and 
postmedian bands, the latter bifurcating near costa, its outer branch running to apex. 
aphanta. X. aphanta Turn. Position quite uncertain. The unique type, a $ from Lord Howe Island, was first 
recorded as “ GidariaV’ (Euphyia), then described as u Xanthorhoel”. Expanse 24 mm. “An inconspicuous 
species of ordinary facies.” Palpus 2%. Forewing apex round-pointed, termen slightly bow'ed, moderately 
oblique; ochreous-whitish, the markings grey, mixed with brownish; basal patch moderate, dentate-edged; 
median band broad, proximal edge curved, distal with a single, prominent, rather obtuse tooth; cell-mark 
linear, set in a paler space; 3 rippled lines between postmedian and the interrupted, dentate subterminal. Hind¬ 
wing whitish, with grey suffusion. Both wings with terminal dots. 
xerodes. X. xerodes Meyr. (25 k G, $). Palpus scarcely over twice diameter of eye. Pectinations 2% or scarcely 
(Meyrick, who gives 3 — 3 y 2 , must have measured from a narrower diameter of the shaft), continuing almost 
to the apex. Forewing variable; veins sometimes partially marked with ferruginous; numerous irregular dark 
lines on a whitish or ochreous-mixed ground-colour, the median band a little darkened; antemedian very oblique 
inward at hindmargin; postmedian with a short, but moderately acute central projection; fringe rather dark, 
marked with whitish. West Australia: Albany. 2 from Perth and district, are much whiter, with strongly 
contrasting median band, extremely like a well-known form of Larentia severata Guen., but I accept Meyricks 
determination, as I notice that they have the angle of the postmedian in front of 1st median sharper than in 
brachyctena. most severata. — brachyctena Turn. (25 d) is probably a synonym, at most a very slight geographical modi-
