504 DESCRIPTIONS OF AUSTRALIAN MICRO-LEPIDOPTERA, 



dorsal and subdorsal lines indistinctly darker green, often obsolete ; 

 head greenish-ochreous. Feeds between joined leaves, or rolled 

 leaves or amongst spun-together flowers or fruits of Correaspeciosa, 

 Boronia ledifolia (Rutacece), Persoonia lanceolata, Grevillea robusta 

 (ProteaccaJ, and a marsh-growing species oi Polygonum, in August, 

 September, and January ; it is probably almost indiscriminately 

 polyphagous. Pupa free amongst joined leaves. 



Generally distributed and abundant ; it occurs at Sydney, 

 Bathurst, Orange, Morpeth, and Kiama in New South "Wales, 

 and also at Melbourne, and in Tasmania ; from August to October, 

 and in January, March, and April. 



From the formidable array of synonyms prefixed, it will be 

 seen that Walker described the twelve specimens in the British 

 Museum as twelve different species, locating them in four distinct 

 genera. The type of Terns retractana, quoted as a doubtful 

 synonym, is a specimen of this species and is labelled Australia, 

 but the description does not at all agree with the type, and as it 

 professes to be taken from an American insect, the specimens 

 have probably been interchanged ; the name therefore cannot 

 stand. The other types are all more or less ordinary varieties.
