MICROLEPIDOPTERA OF NEW GUINEA 
75 
phora Meyrick, L. ochrozona Meyrick, L. eristica Meyrick, L. bisignis 
Meyrick, all from Australia, and L. microglypta Meyrick, from New 
Hebrides. 
Our impression is that in the Papuan and perhaps also in the Australian 
regions the first group of species is much larger than the second one, 
the group with the typical Limnmcia- characters. Therefore we are in- 
clined to bring this group with “decadent characters” (section 1), in 
connection with two Australian names: Ptilochares Meyrick, 1886 and 
Opsizyga Lower, 1903. We tried to obtain material of the genotypes of 
these genera without the evidence of which any statement would be 
inopportune, but did not succeed in laying hands on them as far. There- 
fore we prefer for the time being to maintain the name Limnaecia for our 
entire material, and only to indicate the abovementioned groups without 
attaching any names to them. 
Key to the Papuan species of Limnaecia 
1. Fore wing unicolorous black-bronze picnosaris Meyrick 
Not thus 2 
2. Golden, costal 4 / 6 purple, no markings nephelochalca spec. nov. 
Not thus 3 
3. Orange, basal and apical areas and a patch on dorsum blackish-purple, a bluish- 
purple longitudinal streak in disc ensigera spec. nov. 
Not thus 4 
4. Fuscous, with ochreous-white marginal blotches: two on costa, one on dorsum, 
one in tomus tyrotoma Meyrick 
Not thus, markings not only marginal 5 
5. Pale golden-ochreous with longitudinal grey or fuscous lines 6 
Not thus, no longitudinal lines 7 
6. Four longitudinal lines parallelugrapta spec. nov. 
Two longitudinal lines . . bilineata spec. nov. 
7. Small species: 10 mm; glossy fuscous-white, indistinctly streaked with darker 
along veins simplex spec. nov. 
Larger species: 16 — 26 mm; not thus coloured; mostly with distinct transverse 
markings 8 
8. Pale golden with golden-yellow patches: one elongate, above middle of dorsum 
preceded and followed by a transverse dorsal mark . . . thiosima spec. nov. 
Not thus 9 
9. Light purplish-tawny, markings black and white megaloehlamys spec. nov. 
Creamy-white and bronze-grey, irrorated and marked with fuscous-black . . . 
nigrispersa spec. nov. 
Section 1. Fore wing with decadent neuration. Male with pencils of hairs 
on metapleurae. 
This type may be described as follows. 
Head with smoothly appressed scales. Ocellus small, posterior, often 
not perceptible. Proboscis developed, scaled towards the base. Antenna 
4 / 5 , in the male minutely ciliate, serrulate towards the apex, scape elongate,
