Hindwing ash-grey, in the distal area violettish-grey. An irregularly dentate black s.ubmarginal line and on its 
inside violet scales. Costal margin and in the $ the inner-marginal fold snow-white. 16—18 mm. Queensland. 
— brunnea Rothsch. Ground-colour unicoloured wood-brown, not grey. The white spot at the costal margin of 
the hindwing terminates into a round dot. Apex not concavely cut off. 18 mm. Dutch Hew Guinea. 
B. ambigua Warr. Forewing brownish grey, lines rusty brown. The first from y 3 costal margin to the 
centre of the inner margin, strongly excurved. The second from 2 / 3 costal margin also excurved in the middle, 
then inwards to % inner margin. The space between the lines somewhat darker. At the distal margin behind 
the cell a rusty brown triangular spot with 3 black dots on its inside. Hindwing similar to fore wing with 2 
isolated black submarginal spots on the 2 small tails. Eorewing at the distal margin behind the cell somewhat 
concave. 18 —22 mm. India, Queensland. According to Turner not a species of Dirades, but belonging 
to this genus. 
30. Genus: Aeachnaena Tmr. 
Antennae of $ with one row of pectinations. Neuration of forewing: vein 5 a little above the centre 
of the cross-vein, veins 6 + 7 on a short stalk, 8 + 9 stalked. Hindwing with a strong dent at vein 7, especially 
in the + Costal margin excavated in the middle, with a subapical hair-tuft. Inner margin in the $ rolled up, 
so that veins 2 , 3 and 4 disappear in this bag. In the $ veins 3 and 4 from the same place, in both sexes 
6 and 7 from the same place. Type: euthysticha Tmr. 
A. euthysticha Tmr. Grey, dusted with rusty brown, with a dark rusty brown median band. Its inner 
margin excavated, its distal margin from % costal margin to % inner margin straighter, more distinct. A dark 
apical streak and a rusty brown marginal line. On the hindwing the median band is reduced to a series of spots. 
20—22 mm. Queensland. 
31. Genus: IPterotosoina Warr. 
In the forewing the neuration and shape is as in the genus Epiplema, but the hindwing of the $ cor¬ 
responds with Dirades in the neuration and the presence of an inner-marginal fold with a hair-pencil. Inner 
margin shortened, distal margin irregularly undulated, with a dent at vein T as in Monobolodes. Costal margin 
uniformly bent. At the base of the abdomen a very long hair-tuft on the sides. Type: hilineata Warr. 
Pt. bilineaia Warr. Forewing lilac grey. Lines rusty brown, from y 3 and 2 / 3 costal margin, below the 
latter somewhat excurved, then vertical and parallel to each other to y 3 and % inner margin, the exterior line 
with a projection below vein 4. Some brown marginal spots. Hindwing similar. Exterior line margined with 
brownish ochre, bent at vein 5, both the lines terminating at vein 2 . Yellow-black marginal spots at vein 4. 
Inner-marginal fold white, hair-pencil yellowish. 20 mm. New Guinea. 
32. Genus: Met©s*tliocliilns limps. 
Distal margin of fore wing cut out below the apex. Neuration of fore wing: vein 5 "from the centre of 
the cross-vein, veins 6 -)- 7 on a long stalk, 8 + 9 stalked. In the hindwing 6 + 7 on a long stalk. Type: 
emarginatum Hmps. 
M. emarginatum Hmps. Pale violettish-brown. Eorewing with traces of a curved interior and exterior 
line, as well as a submarginal line. Fringe at the indentation of the distal margin white. Hindwing similar, 
lines straighter. $ on the forewing with a faded brown spot behind the cell. 20— 22 mm. India, Ceylon. 
M. excisum Hmps. Violettlsh-brown. Both wings with an indistinct exterior and marginal line, the 
former curved. Fringe of forewing not spotted white. 20 mm. North India. 
33. Genus: Pseudhyria Hmps. 
Apex of forewing produced, distal margin of hindwing rounded. Neuration of forewing: vein 3 before 
the cell-angle, 6 and 7 from the upper angle, veins 8 + 9 on a long stalk, 11 anastomosing with 12 . In the 
hindwing vein 3 before the angle, 6 and 7 from the upper cell-angle. Type: rubra Hmps. 
Ps. rubra Hmps. Reddish-brown. Both wings with a dark cellular spot and traces of a rusty brown 
interior and exterior line. Fringe golden yellow. 24 mm. North India.
