DICHROMODES. By L. B. Prout. 
rufula. D. rufula Front (lb). A small species, with rather narrow, straight-margined forewing. Conspicuous 
by its strong rust-red coloration (particularly in the central area and beyond the subterminal line); subterminal 
line shaded with red and fuscous proximally. Geraldton, West Australia. 
haemaiopa. D. haemafopa Turn., described from Sea Lake, Victoria, is unknown to me. It is another reddish 
species, but larger than rufula, with a white, dark-sprinkled costal streak, the lines dark fuscous, not red; costal 
and hinclmarginal dark spots near base, the former mixed with red; fringe dirty whitish, divided by a dark line. 
compsotis. D. compsotis Meyr. (1 b). The dark, irregularly mottled forewing has the veins partially ochreous, the 
antemedian and postmedian lines white-margined, the former broadly, the latter moderately; in the median area 
tw T o dark bars (the anterior one crossing the cell-spot) connect the lines; subterminal line slender, whitish, tri- 
sinuate. Hindwing more variegated than in most of the allies. Fremantle, West Australia, hying in October. 
orthozona. D. orthozona Lower is said to be probably nearest to compsotis but apart from the longer antennal 
pectinations (nearly 6 times as long as. diameter of shaft) recognizable at once by the almost straight liries 
which limit the central band, recalling those of orthotis (lb); basal third ferruginous-ochreous, central band 
moderately broad, „fuscous-whitish“. Roeburne, West Australia. 
cirrhoplacet. D. cirrhoplaca Loiver. Likewise only known to me from the description. Silvery grey-whitish, with 
minute and irregular dark irroration ; an interrupted blackish streak on fold; antemedian line slender, waved, 
black, accompanied proximally by a ferruginous band, which does not reach the wing-margins; postmedian fine, 
blackish, with a slight inward projection touching the cell-spot; beyond it a broad ferruginous band which is 
strongly suffused with blackish distally and here sends out three obtuse projections. Pinnaroo, South Australia. 
partitaria. D. partitaria Wall \ (lb). A neat but not very striking species, distinguished from the others in which 
the veins are partially ochreous by having a sharply-defined white marginal band, which almost reaches the sub¬ 
terminal line anteriorly and is confluent with it towards the hindmargin. According to Meyrick common in 
angasi. West Australia in November and December. Occurs also in New South Wales and Victoria. — angasi Fldr., 
only the type known, unfortunately without indication of exact locality, is a large aberration or local form of 
an almost uniformly dark colour with the exception of the whitish distal band of the forewing. 
aristadelpha. • D. aristadefpha Loiver. According to its author very close to the preceding but totally different in colou¬ 
ring and in the shape of the antemedian line, besides other details. „Ochreous, somewhat mixed with ferru- 
ginous-fuscous“, central band dark and well-defined, antemedian line strongly curved in anterior two-thirds and 
with a sharp angulation near hindmargin. Henley Beach, South Australia. 
mesozona. D. mesozona Front (lb). A very distinct species, of a rust-brownish colour, irrorated with white and 
fuscous; the dark central band of the forewing very conspicuous, rather narrow, with its edges rather irregular, 
its proximal boundary-line strongly bent basewards near the costal margin; a conspicuous narrow subbasal band; 
distal area and hindwing slightly recalling partitaria. Nhill, interior plains of Victoria. 
paratacta. D. paratacta Meyr. (1 b). Scarcely to be confused with any other species. The dark central band is 
rather broad, at least posteriorly, its strongest distal projection is behind the middle of the wing; characteristic 
are the subtriangular whitish or light buff costal patch beyond this band and the somewhat ferruginous bar which 
separates this patch from the subterminal line. Described from Sydney, whence come also the specimens in my 
collection. Flies in October and November. 
semicanes- D. semicanescens Front (lb). Much smaller than paratacta, the basal and central areas almost uniformly 
cens. light grey, with some scattered black scales, the distal area a little darker than the rest, whereas in paratacta 
it is paler; the light subcostal patch is not followed by a ferruginous bar and the white subterminal line is 
wanting. Hind wing almost uniformly dark above, beneath paler, with a dark cell-dot and dark distal border. 
West Australia. 
obtusata. D. obtlisata Wall'. (= devitata Walk.) (1 b). Central band rather narrow, slightly wider anteriorly, 
the lines which bound it fine, dentate, thickened somewhat at costal margin; a straighter, thicker, more con¬ 
spicuous dark ferruginous line proximally to the antemedian is generally distinctive of this species, frequently 
also there is a ferruginous band proximally to the subterminal. South Australia to New South Wales in Oc- 
longidens. tober and November. A small form occurs in Queensland. — longidens Prout is a darker form (or closely 
allied species), with central area especially dark, postmedian line twice dentate outw’ards, almost as in anelictis. 
Beaconsfield, Victoria. 
Hospoda. D. liospoda Meyr. is a more dusky, obscurely-marked species, with the lines w r hich limit the central 
area scarcely discernible, except as blackish spots at the costal margin; the head and thorax, vdiich in obtu¬ 
sata are irrorated with whitish, are here uniformly dark-coloured, as is disputata (1 b), which, however, is a
