Inner margin dark. Hindwing greyish-brown with few dark reticulate lines. Both wings with dark spots at 
the ends of the veins. 100—135 mm. Queensland. 
X. coscinota Trnr. (= doddi Rothsch.). Body and forewing olive grey. Thorax with a V-shaped black coscinola. 
marking. Abdomen with brown bands. Forewing with densely reticulated drab lines. A conical black spot 
below vein 2 and a faded spot above it more basad; besides a spot at the cell-end. Traces of an exterior row 
of spots, and black marginal dots. Hindwing of <§ white, of ^ brownish-grey. The distinctness of the spots is 
rather variable. 75—110 mm. Queensland. 
X.houlbert? Oberth. Ground-colour of body and wings of the $ ash-grey with a slight violet reflection. houTberti. 
Forewing with very dense dark reticulate lines, hindwing unicoloured. The $ is unicoloured brown without 
the black margins at the patagia exhibited by the The ends of the veins black on both wings of the 
and $. 62—94 mm. Queensland. 
X. nephocosma Trnr. (96 d). Ground-colour whitish-grey with darker grey striae and spots which are nephocos- 
fadedly defined. Three of these spots form an interior band extending obliquely inwards, two form a median 
band, the two uppermost of each group are fadedly connected. A dark shadow and striae in the centre of 
the inner margin. Traces of a submarginal band. Hindwings of whitish, of $ grey. Thorax and abdomen 
grey in the abdomen of d whitish-grey. 50—80 mm. Queensland. The larva lives in the trunks of Melaleuca 
leucodendron. 
X. phaeocosma Trnr. Thorax grey, patagia with a black margin, abdomen blackish with light seg- phaeocos- 
mental margins and a light end. Forewing whitish with dense dark reticulate lines. An interior and median 
band of large faded dark spots. A light double spot between them below the cell to beyond the lower inner- 
marginal vein. A large dark spot close at the cross-vein. From this spot to the narrow interrupted row of 
spots before the margin it is also often lighter owing to the absence of the black striation. Hindwing blackish, 
the veins of the in the marginal area grey. 120—180 mm. Port Darwin. 
X. lituratus Don. (= casuarinae H.-Schajf.) (96 e). Thorax violettish greyish-brown, abdomen blackish- lituratus. 
brown with light segmental margins and a light end. Forewing greyish-brown with innumerable blackish- 
brown striae which are reticularly connected in the marginal area and fused spot-like in other places. A 
round spot below the base of vein 2, a long stripe in the submedian fold and sometimes also one above 
the inner margin. A long blotch behind the cell above vein 6, and 2 or 3 smaller ones below it. A sub- 
marginal band behind it extends to the stripe in the submedian fold. Hindwing very light at the costal 
and inner margins, the striation only distinct in the distal half. Abdomen of $ and the ground-colour of 
both wings darker. 100—160 mm. Queensland, Tasmania. 
X. fuscus Swh. Dark pinkish-brown, thorax grey outside. Wings with black transverse streaks. Fore- fuscus. 
wing white directly at the base, and with a white spot at the cross-vein from where a white blotch extends 
to the apex. Fringes of both wings with dark spots at the ends of the veins except at the anal end of the 
hindwing. 110—135 mm. Queensland, New South Wales. 
X. donovani Rothsch. (96 c). Body and wings greyer than in lituratus, just as profusely though more donovani. 
finely striated. A black spot at % °f the length at the costal margin, extending into the cell, and a mostly 
smaller one at % of the costal margin. In the submedian fold there is one spot each below the spot at the 
costal margin. A distinctly defined macular stripe from near the apex. Hind wing dark below the cell as 
far as the inner margin. An indistinct row of spots before the margin. Both wings spotted dark at the fringes. 
90—125 mm. Queensland. 
X. mackeri Oberth. Similar to a large lituratus (96e). The lateral margins on the thorax are mackeri. 
narrower white! abdomen brown with white segmental margins, not light at the end. Forewing white, not 
so uniformly densely striated dark. The spots dark reddish-brown. One at the costal margin from near the 
base to the centre of the costal margin. The other marking below and behind the cell is quite similar, 
though stronger than in lituratus, especially the submarginal band is more distinct. The darkening directly 
at the margin is more distinctly defined inside. Hindwing of $ dark brown, somewhat lighter only at the 
margin which shows reticulate lines. Hindwing of $ somewhat darker than in lituratus. 130—175 mm. Queens¬ 
land. 
X. striga Rothsch. (= acontucha Trnr.) (98 a). Body and forewing whitish-grey. A black stripe of siriga. 
fused streaks at the costal margin as far as 2 / 5 of its length, the streaks extending into the cell. A black 
radial streak at the lower inner-marginal vein extends from near the base and is bent up to vein 2; the 
area above this stripe is more purely white. Black dusting in the marginal area, but no lines. Hindwing 
of d creamy white, of $ olive grey, without markings. Both wings with black marginal dots at the ends 
of the veins. 70—90 mm. Queensland. 
X. duponchelii Neivm. Body dark brown, abdomen rusty brown at the base. Forewing dark brown duponchelii. 
with numerous darker striae. Hind wing dark brown, rusty brown at the base, fine striae traceable. $ 85 mm.
