THALLARCHE. By Dr. A. Seitz. 
madllenta. T. macillenta Luc. (13 c) is much smaller than the preceding. Dirty white, the forewing with fewer 
and thinner, more interrupted dentate chains, only behind the middle of the proximal margin a more distinct 
spot; the hindwings all white, without an apical shade and a distinct spot in the cell. East Australia. 
sparsana. T. sparsana Wkr. (13 c) resembles isophragma, but the chains of dots on the white forewings are 
faded except a zigzag-line through the middle and a large, irregular subapical spot. Hindwing pale yellow 
with a dark apical part, extending to the cell-end spot. South and East Australia. 
fuscogrisea. T. fuscogrisea Rothsch. with combed antennae which are sooty brown with white tips; head 
white, thorax dark brown, tegulae whitish; abdomen orange buff. The basal % of the forewing are whitish- 
grey; costa and antemedian zigzag-band dull brown, the small basal dots and median stigma black; the distal 
third is whitish-grey, densely dusted with small brown scales; a broad, dark, dull brown postdiscal band and 
3 brown antemarginal spots. Hindwings orange-yellow with a broad brownish sooty-black apex. Length of 
forewings: 11 mm. Parkside in South Australia. 
oblita. T. oblita Fldr. (13 h). Almost like sparsana, the black dentate lines of the forswings more distinct; 
immediately recognizable by a honey-coloured demi-band broadly extending from the proximal margin of 
the forewing into the cell. Hindwings almost white, very faintly yellowish. New South Wales. 
albicollis. T. albicollis Fldr. (= eliiclionea Trnr.) (13 d). In the same way as sparsana seems to represent a 
faded isophragma, albicollis may be considered as the most strongly marked extreme. Forewings snow-white, 
with strong, thick, partly crossed, transverse zigzag-lines; hindwings of a bright yellow, with a black apex 
and cell-spot. East Australia.

staurocola. T. staurocola Meyr. (13 ^t) strongly recalls the following leptographa, but the discal shade is broadly 
flown out on the submedian fold and along the proximal margin; the marginal shade is confined to the apical 
part and encircles a large, round, white apical spot. Eastern coast of Australia. 
leptographa. T. leptographa Trnr. (13 c). Almost exactly like macillenta, but faintly lined rosy, and on the forewing 
a distinct median and marginal shade. Eastern coast of Australia. 
mochlina. T. mochlina Trnr. (18 m). Whitish, faintly hued pink like leptographa, but the median shade is a 
broad oblique band, the broad marginal shade encloses 2 larger white spots, and also the hindwing shows 
a marginal shade in the apical half. Queensland. 
chrysoclm- T. chrysochares Meyr. (= cosmia Trnr.) (18 m). Like mochlina, but the ground-colour is yellow, 
rcs - and the hindwing shows a very narrow marginal shade at the apex and anal angle. Queensland. 
loschaga. T. loschaga Meyr. (18 m) resembles chrysochares, also dull honey-coloured, but it differs from those 
described before by another curved antemedian band being added to the dark median and marginal bands. 
From Sydney. 
partita. T. partita Wkr. (= tineoides Fldr.) (13 i). Of a more intense yolk-colour than loschaga, from which 
it differs besides by the apical part of the forewing being much broader and of a deeper black, and by a narrow 
black colouring at the base of the forewing, as if it were a 6th band. This may even expand to a real band, 
and the black at the apex of the hindwing may be widened at the same time to a large, jet-black spot exten¬ 
ding to the cell-end. These very much blackened forms thereby superficially resemble the very common 
Eutane terminalis occurring in the same districts, and have been distinguished as amanda Fldr. South East 
Australia. 
jocularis. T. jocularis Rosenst. Thorax, forewing inside, and hindwing yellow, forewing outside whitish; the 
black markings of the forewings are: a basal streak at the costa, an antemedian line before the cell angled, 
interrupted on the submedian, a curved median line thickened to a costal spot, and a broad distal margin 
enclosing light anteterminal spots. On the hindwing a small black median spot and a black band sometimes 
chrysochroa. extending through to the anal angle, sometimes broken off before the median veins. -— In the form chrysochroa 
Meyr. also the distal part of the forewing as well as the proximal part of it is orange instead of white. South 
East Australia. 
phalarota. T. phalarota Meyr. ($ = phaedropa Meyr.) (13 c). Whereas the (figured) $ resembles in its exterior 
entirely a T. staurocola and differs only by the black in the apex of the fore- and hindwing, the black on the- 
o wing has so much increased that on the forewing onty a narrow postmedian band and a spot near the base 
remain white and a black band being broad at the apex surrrounds the border of the hindwing. Sydney. 
More common than most of the other Thallarche.
