MICROLEPIDOPTERA OF NEW GUINEA 
middle of disc, with a few dark brown scales along its edges in disc, along 
cell as far as discoidal vein abruptly dilated by a dark grey suffusion, 
almost connected by a faint somewhat brighter ochreous-browmish 
irroration with posterior half of dorsum, and with tornus; costal patch 
ill-defined, formed by a tawny-grey streak from before middle of costa to 
apex, with lower edge concave anteriorly, indefinite posteriorly; top of 
patch undulate, reaching almost to vein 6 beyond base; markings along 
costa dotted with cloudy dark grey spots; a semicircular row of dark 
brown points beyond and around upper angle of cell extending from vein 
11 to vein 5, one point on angle of cell; another row of similar points 
straight, slightly oblique, from tornus to vein 6 beyond middle; tornus and 
termen suffused with greyish, terminal edge with a dark brownish-grey 
line; dorsal edge dotted with dark grey. ("ilia pale ochreous with an 
antemedian row of dark brown small dots, in tornus dark grey. Hind wing 
pale greyish, faintly dotted with darker grey. Cilia whitish-greyish, with 
an interrupted antemedian shade.

In 1910 Meyrick recorded thirteen species of ‘ ‘Acropolitis’ ’ from Australia 
and Tasmania, to which five species have been added by Turner afterwards. 
A single Papuan species has been described by Meyrick much later, but 
it was placed in the genus Anisochorista. At present three new species from 
New Guinea are added. 
All the Papuan species possess the following features : veins 6 and 7 in 
hind wing stalked, stalk x / 2 , slightly curved, veins 4 and 5 connate, some- 
times stalked (this feature is not recorded of the Australian species) ; white 
discal spot more or less conspicuous, cilia white, barred entirely or on 
basal half with greyish or brownish. The double posterior thoracic crest is 
a feature of little practical value for the characterisation of this genus, as it 
disappears even in slightly worn specimens. 
Tegumen broad, short, narrowed above. Uncus small, curved, top 
cuspidate, bristled below. Socius rather small or moderate, pending. 
Gnathos small, arms narrow, hook short. \ alva broad at base, narrowed 
posteriorly, a patch of long bristles in disc towards base, costa distinct, 
cucullus moderate, separated, sacculus broad, rectangular, little sclero- 
tized. Transtilla complete, lateral knobs strong, with a series of heavy
