MICROLEPIDOPTERA OE NEW GUINEA 
slightly flattened at the base, somewhat clavate, without a trace of a 
pecten. Labial palpus long, recurved, median segment compressed, 
moderately thickened with smooth scales, in large species hardly roughisli 
anteriorly, in small ones smooth, terminal segment slightly longer or 
rather longer than the median, slender, smooth, acute. Maxillary palpus 
small, more or less scaled and obtuse, appressed to the proboscis. Thorax 
in the male with long expansible pencils of hairs from the metapleurae, 
directed caudad and reaching to or beyond the middle of the abdomen 
(in one species these hairs are soldered toget her from the base to before the 
apex, so as to form a shining, sclerotized bristle-like flagellum). Posterior 
tibia variably clothed: with bristly projecting stiff hairs above along the 
basal 2 / 3 , and with a wreath of such hairs at the apex, or with a moderate 
median, and an apical whorl, or only with an apical whorl of such scales, 
or roughly haired above. Fore wing lanceolate, lb furcate, 1c strong, cell 
much narrowed basally, 2 remote from 3 (from 3 / 4 — 4 / 5 of cell), 3 from 
rather before the distinct angle or from the angle, 3 5 separate and 
tolerably equidistant, transverse vein between 5 and 9 obliterate, 6, 7 and 
8 obliterate basally, distinct only towards margin, 7 to costa, 9 apparently 
approximated, 1 1 from beyond middle of cell. Hind wing lanceolate, in 
large species 2 / 3 , cilia 2 1 / 3 , in small ones */ 2 , cilia 4 — 5; 2 5 separate, 
tolerably parallel, 6 and 7 stalked, seldom approximated towards the base. 
Without denuding of the lower surface of the fore wing the constant 
reduction of the parts of the veins 6, 7 and 8, and of a part of the transverse 
vein is hardly perceptible, and one can easily mistake this for the typical 
neuration of Lirnnaecic i : with 7 and 8 stalked, 6 separate (cf . a nice diagram 
of the neuration of L. phragmitella in Spuler, Schmett. Eur., vol. 2, p. 385, 
fig. 142, 1910). 
The type of section l may be regarded as a rather recent decadent 
offshoot of the type of section 2.

$ 10 mm. Head, antenna, thorax pale fuscous-grey. Palpus whitish, 
anterior edge grey. Pectus shining silvery. (Abdomen missing). Legs glossy 
fuscous-white, more or less infuscated above, posterior tibia with a median 
band and an apical whorl of bristly scales, blackish. Fore wing narrowly 
lanceolate. Fuscous-white with a silvery gloss, along veins indistinctly 
streaked with somewhat darker fuscous-greyish. Cilia whitish-fuscous. 
Hind wing glossy fuscous-whitish, cilia whitish -fuscous, faintly purplish- 
tinged.
