discal and postdiscal bands, the latter especially distinct at the costal margin. An irregular row of 
oclireous-yellow submarginal spots distally distinctly dotted black. Hindwing blackish-brown with a bright 
ochreous-yellow marginal part. On the forewing beneath the discal area being above of a pale colour is dull 
oclireous-yellow. The other marking chiefly as above. Body and wings of the $ monotonously whitish-grey 
with' a somewhat brown tint. Forewing with an indistinct white prediscal and postdiscal band. Submarginal 
row of spots as in the <$. Hereto evidently belongs the $ of Rhicnogyna calligama Fldr., hitherto combined 
with P. obliqua Wkr., as is rather distinctly seen from the white bands of the forewings distinctly reproduced 
in the figure; the however, will probably in fact belong to obliqua Wkr. Australia.’ 
P. obliqua Wkr. (= calligama Flclr. $) (32 e, f) resembles cana. The £ differs by the monotonously 
greyish-brown forewings strewn with white scales and the narrower white discal spot, but particularly by the 
prediscal and postdiscal bands being here blackish; by this mark also the $ is discernible from that of P. cana. 
The $ also often has a dark abdomen. Australia. 
P. divisa Wkr. (= rufescens Btlr.) (32 e). Base of forewing in the $ as far as the cell-end, except the 
proximal margin, of a deep dark brown, crossed by a fine, distinct, white transverse line. The white discal 
spot large and distinct. Postdiscal line white, rather distinct, undulate. The yellow, black-dotted submarginal 
spots distinct only on the posterior half of the wing. The posterior part of the wing as well as the whole 
hindwing reddisli-grey. The $ is not described. Australia. 
P. metaphaea Wkr. (= adusta Wkr.) (32 e). Base of forewing in the except the proximal margin, 
of a deep dark red-brown, the submarginal row of spots distinct. $ with a blackish-brown abdomen the apex 
being light grey, hindwing likewise blackish-brown with a broad, whitish-grey border. Evidently closely allied 
with P. obliqua Wkr. and perhaps only a form of it. Australia.

Smaller species, likewise with a very well pronounced sexual dimorphism, though here in contrast 
with Pinara the Ccj are difficult to distinguish. 
Antennae of $ and 9 as far as the apex densely set with long pinnae. Palpi short, porrect and densely 
haired. Wings in the very thinly scaled, diaphanous, forewing trilateral with an almost quite rectilinear 
costal margin, hindwing produced ot the anal angle, in the $ more uniformly and densely scaled, broader and 
more rounded than in the <$. In the forewing veins 6 and 7 on a short footstalk, 8 rising separately before 
the cell-end. 9 and 10 on a rather short footstalk. In the hindwing veins 7 and 8 as in Pinara-, 1 secondary 
vein. Discoidal vein in the forewing vertical, in the hindwing very slanting in a posterior and distal direction. 
The genus is confined to the Australian region. 
Cr. punctigera Wkr. (= bimacula Wkr., anthraxoides Wkr., majus Fldr.) (32 f). £ head white, palpi, 
antennae and body dark brown, only the under surface of the abdomen partly white and on the thorax single 
white hairs and scales. Wings dark greyish-brown, diaphanous. Forewing with a blackish basal part enclosing 
a small white spot; discal spot whitish, indistinct, encircled by 7 distinct black spots; a narrow, white prediscal 
and postdiscal dentate band, as well as a rovv of blackish submarginal spots distally bordered with white. Hind¬ 
wing uniformly greyish-brown, with white marginal scales. $ antennae and palpi dark brown. Head and 
thorax white, the latter with 3 brown spots. Abdomen dark brown with white dorsal spots and a white apex. 
Wings dark greyish-brown as in the the white dentate bands not very distinct, beside the prediscal and 
postdiscal bands another subbasal one. Australia. 
Cr. pinnalis Lac. ( = hyalversa Trnr., [Sit-ina] albicans Swh.) (33 e). $ similar to Cr. -punctigera. 
but easily discernible by the presence of but one black discal spot in the forewing. Wings very transparent, 
the blackish base of the forewing intermixed with white, the prediscal and postdiscal undulate lines not very 
distinct, the latter, however, beginning with a distinct white costal-marginal spot, behind the former, between 
veins 1 and 2, a black spot; of the blackish submarginal spots only 3 or 4 are distinct below the apex of the 
wing, distally bordered by a fine, white dentate line which is very faintly continued still farther posteriorly. 
Hindwing with a narrow white median band parallel to the border. $ antennae dark brown, body white, thorax 
and abdomen with a darker, brown longitudinal streak. Forewing whitish with an indistinct dark discal spot 
and crossed by a number of dark brown undulate lines; a prediscal and postdiscal, white, transverse band each 
bordered by 2 of the dark undulate lines; the blackish submarginal spots are distinct, distally accompanied 
by a white undulate line. At the proximal margin a broad, black spot. Hindwing white, with a dark base, 
a dark greyish-brown discal band and blackish submarginal spots. Marginal scales white with a dark base.
