DICHROMODES. By L. B. Prout. 9 
more brightly marked species, with the fringes mottled with purplish. New South Wales, in September, appa¬ 
rently rare. 
Do explanafa Walk. (2 a). Generally of a very uniform dark colour with fine black and white irro- explunaia. 
ration, the two fairly broad whitish lines standing out very sharply by contrast; the antemedian is almost straight, 
the postmedian characterized by a sharp projection outward in the middle and an unusually deep bend inward 
at the fold. Walker’s type is merely labelled „Australia“, but the species is distributed from West and South 
Australia to New South Wales. 
D. sigmata Walk. (1 b). Only known from Walker’s type, a $ from Sydney. Possibly only a remark- sigmaia. 
able aberration of the preceding; lighter grey, postmedian line of forewing more proximally placed, less deeply 
angulated posteriorly, distal area more variegated, the whitish subterminal line accompanied proximally by irre¬ 
gular dark suffusions. 
D. orthotis Meyr. (1 b). Recognizable at once by the nearly straight yellow-white lines and especially orthoti *. 
by having the central area pale grey, conspicuously lighter than the rest of the wing. Distributed in West 
Australia, November and December. 
D. poecilotis Meyr. (= tridenta Swinh.) (1 c). Forewing with the veins in part thickly streaked with poecilotis. 
reddish ochreous, the lines slender, whitish, blackish-edged distally, the antemedian acutely angulated in the 
middle, the postmedian sinuate inwards posteriorly, followed distally by a fine straight dark line. West 
Australia, common in October and November. Also from Victoria (?). 
D. ioneura Meyr. (lcj. A rather pretty species, with the veins marked nearly as in poecilotis , but with ioneura. 
the ground-colour lighter, more violet-grey, the markings more interrupted and irregular; antemedian line not 
acutely angulated in the middle. Likewise from West Australia, October and November. 
D. fulvida Lower is said to be apparently near ioneura but quite distinct in colouring and in the form fulvida. 
of the lines. Fuscous, densely irrorated with dull whitish, veins with rather thick ochreous streaks; a nearly 
straight dark subbasal band; a broad dentate-edged median band, its proximal edge indented in middle; a sub¬ 
marginal band apparently shaped somewhat as in stiTbiata (1 d). Pinnaroo, South Australia. 
D. euprepes Prout (1 c). Also near ioneura , but with the lines straight, oblique, the head and veins euprepes. 
without reddish colouring; antemedian line incomplete, postmedian accompanied proximally by some wedge-shaped 
black vein-spots. Waroona, Swan River, West Australia, in October. 
D. orectis Meyr. A variable species, said to be common at Geraldton, West Australia. Like indicataria orectis. 
(1 c) it has the cell-spot of the forewing merely outlined in blackish, the centre remaining pale, but that 
species is smaller and has the palpus dark at the base beneath, while in orectis it is whitish. Postmedian line 
angulated outwards in middle, curved inwards behind middle, the central angle marked with a small reddish- 
ochreous spot; proximally bordering the postmedian is a row of triangular spots, somewhat as in euprepes 
(1 c), or these may be confluent into a more or less thick black shade. — The larva feeds on an undetermined 
myrtaceous shrub in November and beautifully imitates the leafy stems of its food-plant; bright green, the 
spiracular line pale yellowish, a series of oblique white marks on sides, meeting on back. Moth in November 
and December. 
D. atrosignata Walk. (= linda Btlr.) (1 c) is likewise variable and is subject to rather strong sexual atrosignata. 
dimorphism. The $ (atrosignata) is conspicuous in having the lines stronger, margined with blackish in the 
median area except towards the costa, and has the postmedian acutely angled in the middle, rather deeply in¬ 
curved behind. The $ has the postmedian less strongly bent and only rarely (form linda ) resembles the $ in 
the sharp black markings. — usurpatrix Prout (= exsignata Meyr., nec Walk.) (lc) is the usual $ form, much usurpatrix. 
more weakly marked than the $, the fine whitish lines sometimes broken up into dots. — atrosignata is common 
in Victoria and New South Wales, apparently in two generations. I have also a dwarf form from Strad- 
brooke Island. 
D. raynori sp. nov. Smaller than atrosignata (1 c). Palpus longer, of a less blackish brown colour, rayncri. 
Antennal pectinations in the G longer. Rather paler, beneath rather more strongly marked. Markings almost 
identical and with similar sexual dimorphism, but the cell-mark of the forewing forms a large open ring, as 
in indicataria (1 c). New South Wales, 3 and 2 $$ in coll. Brit. Mus. collected by Rev. G. H. Raynor, 
the <$3 from Parramatta, end of August. From the wing-expanse given by Meyrick (Proc. Linn. Soc. N. Sth. 
Wales, Ser. 2, Vol. 4, p. 1184), his mention of a „sometimes pale centred" discal spot, and especially his mea¬ 
surements of palpus and pectinations, this was certainly confused by that author with atrosignata. The last- 
named has the shorter palpus and pectinations of indicataria.
