too many unrecognised species. With a much more extensive 
collection, and after an examination of the Miskin Collection 
in the Queensland Museum, I am able to reduce the unrecognised 
species very considerably, and have also to add the many new 
species described since 1891. 
It will be noticed that many changes are made in the 
genera. These are made mainly on the authority of the late Mr. 
L. de Niceville, to whom Mr. It. E. Turner and myself submitted 
a large amount of material. Mr. H. H. Druce, by his published 
writings and letters, has elucidated many difficult points. 
The habitat given, unless otherwise stated, must be taken 
to apply to the coastal strip of 150 miles or thereabouts, for 
very few species are found further inland. Mr. 0. B. Lower 
has taken No’s. 5, 30, 31, 33, 138, 151, 158, 167, 199, 212, 220, 
238, at Broken Hill, and Mr, H. L. Kesteven No’s. 130, 138, 167, 
199, 206, 212 at Bourke. 
That a great deal of work has yet to be done, is only too 
apparent, and some of the difficulty is caused by the same species 
being known under different names in different States ; and often 
two species pass under the same name. In this connection, I 
will be onty too pleased to determine any specimens sent to me, 
and will give full references to the bibliography of the species 
if desired. 
When better, collections are made, particularly of Northern 
forms, with authentic dates and localities, the study of distribu¬ 
tion of species and seasonal change will be greatly aided. 
Especially amongst the Pieridse is seasonal change noticeable. 
I am sure it also exists in the other families, but so few 
collections are accurately dated, and some are even without 
localities, which is very vicious. 
In addition to writings of de Niceville, Druce, and Miskin,. 
I have used Kirby in giving the descriptions of the families. 
To anyone working at this group, the references I give will 
be sufficient, but a further very extensive list is given by 
Miskin’s Catalogue in the Annals of the Queensland Museum,, 
where most of the abbreviations used in this present list will be 
found. Miskin added greatly to our knowledge of Australian 
Butterflies, and if the work of other writers both in and out of 
Australia had been but half as good, the confusion of unrecog¬ 
nised species, which I hope this present list will help to clear 
away, would not have arisen.
