New Australian Lepidoptera.

The insects described in the present paper belong to various 

 families. Most of them have been in my possession for some 

 time, and they include among others a number of interesting 

 forms, mostly bred from the larvse, for which I am indebted 

 to Mr. F. P. Dodd, of Townsville. The types of the family 

 Xyloryctidct collected by Mr. Dodd are in the collection of 

 Lord Walsingham, to whom I am indebted for permission to 

 describe them. There are co-types in my own collection. I 

 have also described several species received from Mr. G. Lyell, 

 jun., of Gisborne, from Mr. H. Tryon, Queensland Government 

 Entomologist, and Mr. R. Illidge, of Brisbane. 



Among the genera, and almost equally among the families, 

 usually loosely known as ^'Bomhyces," there exists at present 

 great confusion in Australian collections. A revision of these 

 families is much needed, and I hope, when time and material 

 (much of it scarce and difficult to obtain) permit, to under- 

 take this, a task in which my recent opportunities of examining 

 Walker's types in the British Museum should prove of service. 

 The Notodontidce I have already in hand, and hope to publish 

 shortly. In the present paper I have received much help by 

 the study of the family and generic definitions in Sir George 

 Hampson's ''Moths of India," and in the introduction to his 

 "Catalogue of the Lepidoptera Phalaense." 



In several instances I have found, after writing my descriip- 

 tions, that I had been anticipated in the naming of the species, 

 but I have published them, in the hope that they may prove 

 serviceable.
