second line angulated towards costa, ferruginous fascia extended 

 to inner margin. 



Newcastle and Sydney, New South Wales ; in September and 

 October, not uncommon, appearing to frequent Eucalypttts. 



i. ACIDALIA, Tr. 



Face smooth. Palpi moderate or short, loosely rough-scaled or 

 filiform, porrected or subascending, terminal joint shoi*t. Antennae 

 in ^ filiform or dentate, ciliated. Posterior tibiae in ^ often 

 dilated, without spurs or with end-spurs only, in 5 with all spurs 

 present or sometimes with middle-spurs absent, posterior tarsi in 

 ^ more or less aborted or rarely well-developed, Forewings with 

 veins 3 and 4 separate, 6 remote from 9, 10 out of 9 below 8, 11 

 connected by bar or anastomosing with 9. Hindwings with veins 

 3 and 4 remote, 6 and 7 stalked or separate. 



A very large genus, cosmopolitan except for New Zealand, 

 where there is only one Australian species. The species are small, 

 inconspicuous, and often extremely similar, requiring very careful 

 examination. In the following specific descriptions five transverse 

 lines are referred to as normally present ; the first, median, 

 second, subterminal, and submarginal. The length of the posterior 

 tarsi of the ^ is stated in terms of the length of the tibiae. The 

 palpi are often very variable in colour, and in direction also, 

 within the limits of the same species ; apparently no stress should 

 be laid upon them in this genus.
