M. rectifascia Warr. Fore wing dark bluish-brown. The two lines are darker. The first from + costal redifascia. 
margin very indistinct, strongly excurved in the middle, to y 3 inner margin, the second broader, faded from 
% costal margin to % inner margin, straight. At the margin a rusty brown line extending around the apex. 
Hindwing somewhat paler. Only the exterior curved dark brown line is visible. 22 mm. Mefor. 
M. pallens Warr. Forewing pale grey, lines rusty brown, similar to rectifascia. On the hindwing the pattens. 
line is less curved. Both the exterior lines nearer to the distal margin than in rectifascia. 22 mm. Woodlark I. 
M. fuscibrunnea Warr. Forewing whitish, in the anterior portion densely dusted with bluish brown, in fuscibrun- 
the posterior portion brown. The lines as in the two preceding species, behind the exterior lines is a pale spot 
at the costal margin. Hindwing grey ( + , the median band brownish. In the <$ the whole hindwing is more 
brownish. 22—24 mm. New Guinea. 
M. schistacea Warr. Forewing dark brown, lines black. Interior line from y 3 costal margin, angular scMstacea. 
in the middle, exterior line from behind % costal margin centrally incurved in the direction of the angle of the 
interior line which is only distinct in the posterior portion. Marginal line black, at the apex broader. Hindwing 
with a black continuous median line. Inner-marginal fold bluish white, hair-pencil yellowish white. 24 mm. 
Salomons Is. 
29. Genus: Balantiuchii Trnr. 
Antennae of with one row of broad pectinations. Neuration of forewing: vein 5 close below the upper 
cell-angle, veins 6 -f- 7 and 8 + 9 stalked. Hindwing of <$ rounded, its inner margin rolled, forming a bag in 
which veins 2 and 3 are concealed. In the $ fine dents at the margin near veins 4 and 7. Veins 3, 4 and 6, 7 
from the cell-angles. Type: platyphylla Trnr. 
B. platyphylla Trnr. Forewing whitish or pale grey. A dark faded line at the beginning of the costal ptatyphytla. 
margin. Interior line quite irrecognizable. A fine black discal spot. Exterior line fine rusty brown, outside 
edged with white, strongly excurved from % costal margin, then strongly inward to % inner margin, where it 
is blackish. A subterminal row of black spots. Hindwing of angular at vein 7, coloured and marked as on 
forewing. Exterior line in the $ delicate, uniformly bent, in the $ angular, more distinct. A dark discal streak 
in the $. 25 mm. Queensland. 
B. microthyris Trnr. Whitish-grey, densely dusted with a darker grey. Two greyish ochreous lines microthyris. 
from V 2 and % costal margin. Interior line obliquely distad, the other line excurved, both extending to the 
centre of the wing. Fine dark submarginal dots. Hindwing with a broad dark median band. The is disting¬ 
uished from platyphylla by the scaled spot near the base above vein 1 on the forewing. 20—25 mm. Thursday I. 
— According to Turner, annulifer Warr. is synonymous to this species. 
B. mutans Btlr. (= annulifer + rhombifera $ Warr., leucocera Hmps.) (59 k). Similar to Tirades mutcms. 
adjutaria Wkr. (59 h). Forewing pale brown, with a dark brown semicircular spot at the centre of the inner 
margin, to the edges of which two fine brown lines are bent from the costal margin before and behind the middle. 
A light curved line from the centre of the costal margin to the anal angle. Hindwing dark brown, with a lighter 
bent median band. In the $ ( rhombifera ) the exterior line on the forewing extends on vein 4 inwards to the 
interior line. The enclosed area is darker than its surroundings and touches the spot at the inner margin. Hind¬ 
wing uniformly dark, only the edges of the median band lighter. 22—25 mm. India, Salomons Is., Alu, 
Trobriand Is., Timor. 
B. seminigra Warr. Forewing greyish-brown. First line only indicated by the margin of the somewhat seminigra. 
darker basal area before the centre. Exterior line reddish-brown, outside lighter and edged with grey, from % 
costal margin obliquely distad, in the middle angled, to % inner margin, where it touches a blackish-brown 
triangle. Hindwing blackish-brown with a broad brown radial stripe across the centre of the wing. Interior line 
composed of black dots, exterior line reddish-grey, angled. 26 mm. Queensland. 
B. cyclocrossa Trnr. Near mutans (leucocera Hmps., 59 k) and Dir. leucocephala (p. 597), but separated cyclocrossa. 
from them by the absence of a distinct postmedian line in the forewing. Antennae and legs white, excepting 
the brown forelegs. Queensland (in the Bunya Mts.), found in January, 22—26 mm. 
B. albllla Warr. Very similar to seminigra. Forewing greyish-white, both lines indistinct. At the albuta. 
inner margin between them a high triangular dark spot. Hindwing with a light radial stripe in the centre and 
at the inner margin, as well as two rusty brown lines, both obtusely angled at vein 4. 15 mm. Queensland. 
B. acutilinea Warr. Likewise similar to seminigra. Forewing pale brownish-grey. Both lines indistinct, acutitinea. 
Interior line angled in the middle, exterior line excurved close below the costal margin, then straight as far 
as vein 3 and continued almost to the centre of the inner margin. These lines and a submarginal line greyish 
ochreous. Hindwing nutbrown, in the marginal area grey. Interior line of brown dots, angled; exterior line 
greyish ochreous, bent. 22 mm. Penang. 
B. decorata Warr. Forewing grey, without distinct lines. A dark spot on the cross-vein and a blackish- decorata. 
brown vertical shadow from 3 /4 costal margin. Black submarginal dots from the apex to the centre of the wing.
