round rusty yellow spot in the centre of the wing does not reach the margins and encloses spots of the 
light ground-colour. The veins are black also behind this large spot, with white streaks between them. Hind¬ 
wing dark brown. <$ 30 mm. Queensland. 
Z. perigypsa Lower. Body dark brown with some white scales. Eorewing dingy white with fine dark perigypsa. 
striae, very densely so below the costal margin which is not striated. Hindwing pale whitish-grey with some 
fine dark reticulate lines. <$ 44 mm. New South Wales. 
Z. tripartita Luc. Body bluish-grey. Eorewing dark reddish-brown, dusted with bluish-grey. Fine tripartita. 
black striae between the veins. The first third at the costal margin is black, forming the ground-line of a 
triangle the apex of wdiich extends towards the inner margin as far as % of the width of the wing. Behind 
it at the costal margin there are 4 spots from which lines proceed. A black spot at % of the costal margin 
extends towards the centre of the distal margin without reaching it, but dividing towards the apex and 
anal angle. Hindwing dark brown, dusted with grey, with darker striae. 44- -50 mm. Brisbane. This and 
the preceding species surely do not belong to Zeuzera. 
Z. eumitra Trnr. Body and forewing white, foiewing with black marking. 7 quadrangidar spots at eumitra. 
the costal margin in the interior half. 3 transverse rows of spots in the basal third, 3 erect streaks behind 
them before the centre of the inner margin. A narrow band interrupted at the white veins extends from % 
of the costal margin to % of the inner margin, small spots in the disc before this band. A double sub- 
marginal row of spots and a single marginal row. 3 spots in the distal part of the costal margin, the last 
spot being largest. Hindwing white with black marginal spots at the anal angle and apex. ^ 52—56 mm. 
Brisbane. Larva in Eugenia ventenatii. 
9. Genus: Parazeuzera B.-Back. 
Palpi short. Antennae of finely serrate. Tibial spurs not stated. Wings shaped like those of Cossus. 
Forewing: veins 3—5 separated from each other, vein 6 and 7 8 from the upper cell-angle, 9 and 10 from 
the anterior edge of the cell near the angle, 11 far basad. No areole. Hindwing: veins 3 -5 separated from 
each other, 6 and 7 likewise separated. A bar between 7 and 8 as in Zeuzera. Type: celaena B.-Bak. 
P. celaena B.-Bak. (96 d). Thorax black with golden brown areas, abdomen black with a golden celaena. 
brown base. Porewing greyish-black with fine black lines and spots. Darkest above the inner margin. Postal 
margin with 4 black spots and a black apex. Hindwing dark brown with a slight metal gloss, rather pointed 
at the apex. $ 38 mm. New Guinea. 
P. aurea B.-Bak. (96 d). Body golden brown with a reddish gloss. Eorewing the same, with a some- aurea. 
what darker spot at the cell-end, and darker scales at the inner margin. Hindwing pale grey with a yellow 
tinge, reddish-brown in the original figure, diaphanous. 40 mm. New Guinea. 
10. Genus: Iriioses Trnr. 
Antennae of $ pectinated to the tips. Dorsum of abdomen very hairy. Eorewing: vein 2 before the 
cell-angle, 3 + 4 stalked, distantly separated from 2, veins 7 + 8 + 9 stalked, 10 and 11 separated, 11 not 
far from the cell-angle. No areole. Hindwing: veins 2—5 separated, 6 and 7 from the upper cell-angle. 
1. littleri Trnr. Thorax and forewing pale grey with indistinct white striae. A fine dark brown sub- littlcri. 
basal line is slightly bent outwards. A costal-marginal row of somewhat lighter spots. 2 or 3 dark transverse 
streaks before the centre of the wing. Apical area dark grey, 3 black spots before it. Hindwing greyish-brown, 
fringe pale grey. $ 27 mm. Tasmania. 
11. Genus: Xyleutes Hbn. 
This genus has already been dealt with in Vol. II, p. 418, and Vol. XIV, p. 546. Houlbert has written 
monographies on most of the species treated upon here. The order adopted by him is also used here as far 
as possible. The species of this genus are becoming more common of late, owing to the decreasing number 
of their enemies, the Australian negroes who eagerly pursued the larvae in former times. 
X. grisea nom. nov. (= edwardsi Houlb. nec Tepp.). Thorax and forewing greyish-white, densely dusted grisea. 
black, with a more or less long dark blotch at the anterior edge of the cell. A series of short blotches 
before the distal margin may also be absent. Abdomen likewise grey. Hindwing darker than forewing, 
especially at the base and inner margin. 100—135 mm. Adelaide, Kuranda. 
X. magnifica Rothsch. Forewing pale grey, 2 <3$ and one of 2 $$ with scarcely traceable dark spots magnified. 
between the veins in the marginal area. Hottlbert’s figure exhibits also a longitudinal streak below the 
costal margin. Hindwing white at the costal margin, the rest nut-brown, not grey as in grisea. Thorax grey, 
abdomen nut-brown, grey at the end; the <$ abdomen also with a grey dorsal stripe which is also exhibited 
by the $ in the figure quoted above. 135—200 mm. Brisbane.
