[Read 1st February, 1875. ] 
I HAVE, for some time past, contemplated writing a descrip- 
tive Catalogue of the Rhopalocera of Australia, somewhat 
after the plan of my friend Trimen’s admirable treatise on 
the African butterflies—Rhopalocera Africe Australis ; 
indeed, I have a great part of the MS. ready for the press, 
but one cause or another has, for months past, prevented 
my continuing it; and, as I do not at present see my way 
clear to complete it, I propose in the paper now before the 
Society to describe several species which I have deter- 
mined to be new to science (the types of which I am 
anxious to secure for the National Collection), and at the 
same time to make a few observations upon the work of 
other authors who have written on the butterflies of 
Australia.
