X. boisduvali Rotlisch. (97 c). Forewing ash-grey with a faded exterior row of spots and a submarginal 
row, the distinctness of the spots varying much in both rows. Hindwing grey at the costal margin, the 
rest blackish-brown, with irregular radial grey spots at the margin. Thorax grey, black in the middle. Ab¬ 
domen black with narrow greyish-white segmental margins. 150 -210 mm. Queensland. 
X. rothschildi Oherth. ( maculatus Rothsch.). $ ground-colour more ash-grey, paler at the apex in 
the centre of the wing. A long dark streak in the cell. An exterior row of spots close behind the cell. A 
large black spot below the cell is cut by the submedian fold and is nearer to the base of the wing than to 
the exterior row of spots. A row of strigiform spots near the margin. Hindwing brownish-black. 210 mm. 
Brisbane. 
X. tumeriana Oherth. Size and distinctness of the marking intermediary between boisduvali (97 c) and 
the following af finis. Forewing grey, the two rows of spots of boisduvali indistinctly defined. Hindwing 
blackish-brown, apparently darker in the $ than in the <$. Thorax grey, abdomen black with white segmental 
margins and a grey median line and end. $ with a somewhat darker thorax, abdomen blackish-brown, grey 
at the end. 110—150 mm. Queensland. 
X. affislis Rothsch. The submarginal row of dark brown spots on the foiewing large and distinct, the 
exterior row of spots as in tumeriana , the uppermost spot behind the cell being here also more intense than 
the others. Besides a dark shadow in the cell-end and one basad below the cell. Fore wing of $ not so grey 
as in the but more yellowish-grey. Hindwing dark red-brown. Black spots at the ends of the veins on the 
forewing, also on the dark hindwing, though less distinct. The size varies much. $ 100—140 mm, 2 140 
to 210 mm. Brisbane. 
X. sordida Rothsch. $ similar to boisduvali (97 c), but the thorax dark brownish-grey, not pale grey 
with a black centre. The spot at the cell-end of the forewing is almost extinct, while it is distinct and large 
in boisduvali. Hindwing lighter brown. According to Oberthur, sordida may be only a small form of tumeriana. 
The following differences might be stated: $ and $ with a lighter forewing; thereby the two rows of spots 
become more distinct, as in affinis. No black spots at the margin. The dark abdomen with light segmental 
margins and a light end. Hindwing of <$ much lighter than in tumeriana , except at the base, somewhat lighter 
in the $. $ 120— 135 mm according to Rothschild ; ^75mm, $ 105 mm according to Oberthur. Brisbane, 
Taylor Range. 
X. mixta Pagst. (96 d). Body and forewing yellowish-brown, the marking on the fore wing reddish 
blackish-brown. A flatly-triangular spot at the costal margin begins close behind the base. A spot in the 
shape of a slanting square extends from the base of vein 3 obliquely outwards to the costal margin and 
from this border distally. Behind the prolongation of this oblique border as far as the inner margin, the 
ground-colour is more or less intensely darkened reddish as far as the distal margin. Besides the whole 
wing is covered with dark striae. In the type alone the second spot is so distinct, in all the others only the 
basal triangle is distinct, but the slanting square very faded. Hindwing somewhat more reddish, striation in¬ 
distinct. $ 34—48 mm. Amboina, New Guinea. Key I. 
X. maculatus Sn. (96 e) resembles a large, more completely marked mixta. The basal band as well 
as the very irregular exterior band are continued to the inner margin. Besides a submarginal band is present . 
The two latter may be faded. Dark reticulate lines at the margin. Hindwing somewhat lighter brown. 
$ 60—90 mm. Amboina. minimus Houlbert, from New Guinea, most probably belongs to this species. The 
following differences may be stated: the apex of the basal triangle is situate more distad, the lower half of 
the slanting square is absent, a few small whiter spots in the centre of the wing between the reticulate lines. 
40 -46 mm. — A very badly damaged specimen from Mt. Maeander, New Guinea, may belong to this species, 
though the name minimus is unfit considering the expanse of 60 mm. 
X. polyploca Trnr. (98 b). Body grey, only the thorax broadly black in the middle. Wings pale grey. 
Forewing striated black and with dark grey spots. In Oberthur’s figures the spots look darker than the streaks. 
A large almost triangular spot at the costal margin begins close behind the base and its apex extends to 
the inner margin. A short triangular spot at % of the costal margin, and a long and broad one. obliquely 
inwards below it extends to the inner margin. Besides small submarginal spots. Fringe spotted dark. The 
dark spotting is much more extensive in the $. Hindwing more finely striated than forewing. 42—58 mm. 
Port Darwin. Apparently very common. The figured specimen from Cooktown has no dark thorax and is 
also generally lighter, but it nevertheless belongs to this species here. 
X. lichenea Rothsch. (= olbia Trnr.). Body brownish-black. Thorax lighter laterally and behind, 
abdomen with a grey end and median line. Forewing brownish-grey, the marking black. One large irregular 
black spot each in the cell near the base and at its end; the latter spot mostly obliquely from before the 
centre of the costal margin to the base of vein 3. A band from below the apex to vein 2 is broad in its 
lower end, formed of distally coherent spots between the veins. The ground-colour behind it is narrowly 
perceptible, reticulate lines only again directly at the margin. A stripe of reticulate lines below the cell.
