longer, acute. Forewings : 2 and 3 separate, tolerably parallel, 

 7 and 8 stalked, or (in exotic species) sometimes 6 and 7 out of 

 8, 7 to costa. Hindwings 1, elongate-trapezoidal, apex acute, 

 produced, termen emarginate, cilia 2J-3 ; 3 and -i remote, 5 

 nearer 6, 6 and 7 remote. 



This genus, hitherto represented by a few European species, is 

 considerably developed in Australia, and therefore probably occurs 

 also in the Indo-Malayan region; one species, allied to an Aus- 

 tralian form, occurs in New Zealand. It is distinguished from 

 Aristotelia only by the tuft of the palpi, and as this is very short 

 in some species, care is required; the genus is derivable from 

 Aristotelia, and it seems not improbable that Australia is its place 

 of origin. The larvae are probabl}" often attached to grasses.
