oblique: vein 11 from middle, vein 8 to apex. Glossy white, in certain lights 
faintly touched with isabel towards the base and the anterior half of the 
costa. Anterior fourth of the costal edge with a narrowed blackish streak; 
dorsum pale isabel-greyish, this colour very faintly extended over the base 
of the wing, hardly reaching above the iold, extended also as a narrow 
marginal streak in the tornus to the base of the termen, continued along 
the termen to the apex as a very faint greyish marginal shade, which is 
visible only in certain lights; cilia snow-white. Hind wing glossy white, 
cilia snow-w r hite. 
Tegumen erect, rather narrow. Uncus curved downward, truncate. 
Gnathos triangular, curved upward. Socii, pending pads. Valva large, very 
broad, lower edge angularly projecting in the middle; sacculus broadei 
anteriorly, abruptly narrowed beyond V 3 of the valva, continued as a long 
curved band covered with appressed bristles to below the top of the valva. 
Anellus broad, over 1 / 2 . Aedoeagus moderate, curved, with a subapical 
tooth. (Slide no. 884 D, type.) 
Araucaria Camp, 800 m, March 8, 1939. One specimen. Superficially 
close to A.symmetra Meyrick. The male genitalia are considerably differing 
from those in the preceding species, and possibly indicate a separate genus, 
but the differences are not supported by other characters, therefore for 
the time being we leave the species in the present genus.
