odontias', the central band, moreover, in less obliquely placed than in stilbiata , has an indentation in the middle 
on its proximal side and a small projection in the middle on its distal side; a rather conspicuous dark sub- 
basal band; the whitish line (or narrow band) which borders the central area distally is broad anteriorly, nar¬ 
row posteriorly, slightly oblique outward at hindmargin; beyond it comes a fine brown line, then an irregular 
blackish band shaped as in stilbiata but much more conspiciuous, the distal area remaining pale. Kelso, New 
South Wales, only two examples known to me. 
D. perinipha Lower is said to be remarkable in having the distal margin of the hindwing unevenly wa- perinipha. 
ved. Further distinguished by its pale colouring. Head, palpus, thorax and wings whitish; markings dark fus¬ 
cous; antemedian and postmedian lines thick, the former not reaching the costal margin, slightly projecting 
at the fold, the latter from 3 / 4 costa to near anal angle, dentate throughout and with a bidentate projection in 
the middle; a dull subterminal shade. Pinnaroo, South Australia. 
D. confluaria Gnen. (Id). A very distinct species, unique in the broad whitish subcostal streak, very conflnar\> j. 
oblique central one, bent postmedian and straight subterminal and terminal. Common and widely distributed in 
the southern parts of Australia, October to December. 
D. personalis Fldr. (= ophiosema Lower ) (1 e). A very remarkable and unmistakable species, unique personalis 
in the arrangement of the dark markings, the elongate spot in the middle of the wings flat anteriorly and gently 
curved posteriorly, the hinder dark marking forming a projection proximally, distally confluent with a sinuous- 
edged submarginal band which tapers to a point near apex. West Australia. 
D. triglypta Lower. A rather large species, doubtfully referred by its author to this genus, the head triply pin. 
in the unique type being in bad condition. Forewing elongate; brownish ochreous, the lines rather thick, black; 
postmedian curved outwards in middle, edged proximally with ferruginous, distally with clear white; subtermi¬ 
nal line sinuous, clear white, dark-bordered proximally. Dundas, West Australia, in November. 
D. trychnoptila Turn., founded on a single male in poor condition, differs from all other known species trychnopiila. 
in having 3 tufts of raised scales on the costal margin of the forewing between the base and the discal spot 
and by the exceptionally short antennal pectinations, which are only as long as diameter of shaft and as broad 
as long. Dirty whitish with 3 transverse lines, the first and second arising from the second and third tufts, 
the third subterminal. Zeehan, Tasmania. 
D. steropias Mexjr. Palpus long. Forewing rather elongate, fuscous, with irregular light suffusion; steropias. 
four small tufts of raised scales, proximally blackened, the first two being subcostal, placed near the base and 
at one-fourth; lines dark, slender, the postmedian sharply dentate throughout. West Australia, in November. 
D. nexistriga Warr. (lc). Related to steropias, but very distinct. Forewing light wood-brown with some nexisiriga. 
fine dark irroration; a tuft of raised, mostly blackened scales at base of cell, giving rise to an irregular black¬ 
ish longitudinal streak which runs along the median vein, then between the first and second radials and 
finally rather more oblique to distal margin near the apex; transverse markings indistinct and incomplete. 
Roebourne, West Australia. 
D. ptilomacra Lower. „The most remarkable of the genus, nearest steropias Meyr., but differs in length plilomacra. 
of palpi and especially antennal pectinations of $. “ The latter are said to be nearly 12 times as long as dia¬ 
meter of shaft, the palpus 6 to 8 times diameter of eye. Forewing fuscous, with four small tufts of raised 
scales, the first two being subcostal and hindmarginal at about one-fourth; lines white; a number of irre¬ 
gularly placed cheese-coloured streaks. South Australia. 
D. niger Btlr. (2 a). Both wings dull black, the forewing with the central area faintly discernible on niger. 
account of very slightly paler shades which bound it and especially on account of the deeper black costal and 
median spots which indicate the two lines; cell-spot also faintly discernible. Near Nelson, New Zealand, resting 
on bare ground in the hot sunshine in openings in the birch forest at 1500 to 2000 feet altitude. 
D. gypsotis Meyr. (= niger Meyr. nec Btlr.). Forewing white, slightly mixed with grey, hindmargin gypsotis. 
and hindwing darker grey; bands of forewing (subbasal, antmedian and postmedian) black, slender, the two 
latter thickened at costa, the postmedian sharply angled in the middle, connected behind middle with the ante- 
median by a suffused bar and closely followed distally by a rather broad grey band. Lake Wakatipu, New 
Zealand at about 1500 feet altitude, taken in December. Unknown to me. 
D. sphaeriata Fldr. (= petrina Meyr.). (1 e). Stonegrey (pale grey with dark irroration), somewhat sphaeriata. 
variable in colour but generally with a slight yellowish admixture at least in the pale area beyond the central 
area, while this latter remains rather more slaty; lines nearly parallel, slightly thickened at costa, in middle,
