at the end. Only two species belong to this genus, of which at least argentata is very variable. The species 
of the genus Abantiades H.-Schaff. have the same scheme of marking, but they are distinguished by the 
antennae showing only two rows of antennae. It is not advisable to use the generic name Pielus Wkr. , although 
Pfitzner had used it, as Walker had united therein species with antennae exhibiting two and three rows of 
pectinations. These genera have been thoroughly elaborated by Tindale only a short time ago, and it was 
proved that former authors had made considerable mistakes. 
T. argentata H.-Schaff. (= argenteus H .-Schaff., labyrinthica Meyr., hydrographus Swh.). The species argentata. 
is figured as labyrinthica on pi. 75 a and c; already Meyrick, the author of the genus Trictena, had mixed up 
argentata H.-Schaff. and labyrinthica Don. Thorax and forewings of <$ dark reddish-brown, abdomen and hind¬ 
wing somewhat lighter. A very irregular silvery white stripe at the lower cell-margin and at the cross-vein is 
dentate and sometimes interrupted. A submarginal band proceeding from the apex may be broad or dissolved 
into small spots. — atripalpis Wkr. differs in the prolonged radial band being united with the marginal band, 
but considering the enormous variability of the species it is of no use to denominate forms. There may also 
be a row of white spots proximally to the marginal band, or an indistinct one directly at the margin, and 
peculiar twisted lines frequently also replace the row of spots. The $ is considerably lighter and more indis¬ 
tinctly coloured and marked. 100—180 mm. Queensland, New South Wales, South Australia, Tasmania. The 
species is very common, especially in arid districts. A captured $ deposited the fabulous number of 29 100 
eggs, and that was not even its whole stock! This enormous number, however, is necessary, because the larvae, 
puppae, and imagines are eaten in masses by the natives. 
T. argyrosticha Trnr. (100 b) is extremely similar to argentata, but somewhat lighter. According to argyrosti- 
the original description, the radial streak on the forewing is “rather broad”, but the only figure disposable 
by Tindale shows it to be'rather uniformly narrow. The submarginal stripe is fine, but continuous, not 
divided into pieces as in those argentata which have a feeble band. Twisted spots and additional white spots 
occur also in argyrosticha. The inner margin of the forewing is broad pale brown. The pale brown hind¬ 
wing is sometimes reddish at the anal angle. <$ 106—120 mm. Queensland. 
5. Genus: Bordaia Tind. 
Neuration and scheme of markings not different from Trictena. Separated by shorter palpi and the 
antennae showing only two rows of pectinations. All the 4 species belonging to this genus have only re¬ 
cently been described. Type of genus: pica Tind. 
B. pica Tind. (100 d). Antennae relatively long, pectinations thin. Thorax greyish-brown, abdomen pica. 
with white hair. Forewing broad, somewhat diaphanous, greyish-black with a silvery white marking. The 
irregular radial stripe is similar as in argentata, but prolonged yet behind the cross-vein as far as into the 
space between veins 7 and 8. Submarginal band uniformly broad and connected above vein 4 obliquely 
upwards with the other one by a bar. Within the submarginal band a row of 6 white dots, besides an inter¬ 
rupted white marginal line. Hindwing somewhat diaphanous, greyish-white, darker in the marginal area. 
$ 52 mm. South Australia, West Australia, and ( ?) Victoria. 
B. moesta Tind. (100 b) is somewhat like the species of Oxycanus owing to the concave costal margin moesta. 
of the forewing. Body brown, forewing dark brown. A white radial silvery stripe from near the base does 
not extend around the cross-vein, but it proceeds a little beyond the origin of veins 3 and 4. At a small 
distance above it, between veins 5 and 6, a white band begins, which is horizontal at first, and then bends 
round towards the apex. Above the latter band there is another, almost parallel band.’ Besides a submarginal 
band in the lower part. Base of hindwing and base of abdomen with white hair. $ 62 mm. West Australia. 
B. furva Tind. Antennae of <$ with stronger pectinations. Thorax brown, abdomen lighter, especially jurva. 
at the base. Forewing blackish-brown, darkest at the base. A broad submarginal black band from the apex, 
where the white band extends in Trie, argentata. One rectangular white streak each in the band above and 
below vein 6, as well as at veins 5 and 8. Numerous light-dark twisted lines proximally to the black band, 
similar to those sometimes exhibited also by argentata (75 a, c as labyrinthica). Hindwing greyish-brown. 
120 mm. West Australia. 
B. paradoxa Tind. resembles pica (100 d) in the broader shape of the wings. Thorax reddish-brown, paradoxa. 
abdomen paler, somewhat pink. Forewing uniformly reddish-brown without any marking. Hindwing paler 
reddish-brown, with creamy white and pink hair at the base. Abant. hyalinatus (97 d <$, 78 a $ as ingens) 
may sometimes look similar, but it has much smaller wings. 107 mm. West Australia. 
6. Genus: Abantiades H.-Schaff. (Pielus Wkr.). 
It corresponds with the two preceding genera in the neuration and the strong build. Antennae of £ 
with one row of pectinations, the lamellae partly broad, partly very broad in the different species. Only in
