DICHROMODES. By L. B. Prout. 
berthoudi. D. berthoudi Front (lc). Dark bluish grey, irrorated with whitish and more sparsely with fuscous; 
differs from citrosignata in having the antemedian line slightly angled ontward at costal and median veins, the 
postmedian irregularly dentate and sinuous; from indicataria in its larger size and small, not pale-centred 
cell-dot. Waroona, West Australia, in October. 
albitada. D. albitacta Front (1 c). Bather above the average size for the genus; basal and central areas darkened, 
the latter moderately broad, crenulate on both margins, somewhat constricted behind the middle; postmedian 
line represented by well separated white dots. Antennal pectinations rather long. Nhill, interior plains of 
Victoria, in November. 
I'uscioL. D. euscia Meyr. (1 c). Rather suggests a large citrosignata $ in the heavy black shade which accom¬ 
panies the postmedian line, though this is more obtusely angled in the middle and more gently curved poste¬ 
riorly; but the antemedian is reduced to a few blackish dots. New South Wales, October and November, also 
from Tasmania. 
ophiuchu. D. ophiucha Meyr. „Fuscous, irrorated with whitish; a short blackish mark beneath costa almost at 
base; a short outwardly oblique blackish streak from costa at x / 3 ; a short longitudinal blackish streak in middle 
of disc; an obscure cloudy darker dot on costa at 3 / 4 .“ Distinguished by the absence of the postmedian line. 
Sydney, August and November. 
Indicataria. D. indicataria Walk. (1 c) is an inconspicuous little grey species, apparently variable and possibly em¬ 
bracing two or three species which have not yet been differentiated. Generally recognizable by the cell-mark 
of the fore wing, which consists of an open ring instead of a dark spot or dot; lines fine, finely crenulate, whitish- 
edged. Walker’s type, from Swan River, is rather larger and paler grey than the forms from Victoria etc. Differs 
from raynori, apart from structure, in its greyer colour and more crenulate postmedian line. 
ornata. D. orriata Walk. (1 d). Not appropriately named, as it is a rather sober dark-grey species; sometimes, 
however, the central area of the forewing is decidedly darker than the distal; antemedian line weak, puncti- 
form; postmedian well expressed, feebly or scarcely sinuate, nearly parallel with the distal margin, finely pale- 
edged distally, often shading off gradually into the ground-colour proximally. S. E. Australia to Queensland, 
in two generations. 
triparata. D. triparata Walk. (= molybdaria Walk, nec Guen.) (2 a). Has the median area distinctly darkened 
rather narrow, its distal edge pointed in the middle and forming a regular proximal curve in the posterior 
half; the whitish bands on each side of it rather broad, divided by a fine line; apex whitish. New South 
Wales, Victoria and West Australia, August to December. 
strophiodes. D. strophiodes Lower (1 d). Somewhat similar to triparata but more variegated, the projection in the 
distal edge of the median band more acute, the subbasal dark band developed in posterior half only, the fine 
lines in the pale areas shaded with bright rust-colour. Range as in the preceding species, including South 
Australia. 
me.sogonia. D. mesogotlia Front (Id). Forewing shaped nearly as in the two preceding, hindwing with the costal 
margin rather less elongate. Forewing with subbasal dark mark still less developed, less oblique than in 
strophiodes ; central band broader with two comparatively equal distal projections; coloration similar but less 
variegated. Sea Lake, Victoria, in January. 
consignaia. D. consignata Walk. (— petrilineata Walk.) (1 d). A rather pale grey species, the wings with more 
pointed apices than most of those which precede, the anterior half of the termen being almost straight or even 
feebly concave. Very characteristic are the broad whitish, dark-edged lines which bound the central area and 
the curved dark line beyond this area, which run almost into the apex. West Australia, South Australia, Vic¬ 
toria, New South Wales, October to December. 
rimosa. D. rimosa Front (Id). Similar in shape to the preceding. Palpus not quite as long as in confluaria (1 d). 
Antennal pectinations long. The dark ground-colour is very strongly frosted with white scales, the anteme¬ 
dian and postmedian lines indicated by white vein-spots edged anteriorly and posteriorly by dark ones; a strong 
dark shade proximally to the subterminal. Sea Lake, Victoria, in October. 
stilbiata. D. stilbiata Guen. (= plusiata Walk.) (Id). A very glossy species, the median area longitudinally 
dark-shaded rather than uniformly dark: the pure white line which bounds it distally is broad anteriorly, gra¬ 
dually narrowing, and makes a sharp bend about at the fold, thence running obliquely outward to the hind- 
margin. Generally common in the summer, Tasmania to New South Wales and South Australia. 
D. exocha Front (2 a). On account of the pale head this species would perhaps be better placed near 
exocha.
