The forms may be distinguislied as follows : — 



1. {Aora tT/pt'ca, Kroyer.) — Basos with a tooth projecting 

 forwards on the anterior margin ; carpus longer than the

 and broader than propodos ; meros with small tuft of setae 

 on posterior margin.

The following is an account of a small collection of Lepido- 

 ptera from youth Australia forwarded to the British Museum 

 by Dr. Lucas, of JMelbourne. 



A number of the specimens were unfortunately in poor 

 condition, being either broken or so much worn as to render 

 identification difficult ; and description, in the case of some 

 possibly new species, undesirable. I am nevertheless enabled 

 to describe twenty-eight species, in better condition than those 

 just mentioned, as new to science. 



The IVIicrolepidoptera were well represented, as one might 

 expect in collections from this region. 



]\Ir. Meyrick's labours in this division of Lepidoptera 

 afforded me much aid, though I discovered one or two
