this group, though in other families of Lepidoptera they may be 

 less reliable; the ciliMted male antennae of the Ilemithea-group, 

 for instance, separate this group of genera sharply from its 

 allies. 



For our knowledge of the Australian species we are mainly 

 indebted to one of Mr. Meyrick's valuable papers(Proc. Linn. 

 Soc. IST. S. Wales, 1887, p. 835), which will always remain classical. 

 Since its publication the number of known species has been 

 much increased, especially from the northern part of the conti- 

 nent; and a more minute study of certain details of structure has 

 necessitated considerable generic alterations, without, however, 

 in any way affecting the characteristic accuracy of Air. Meyrick's 

 work. Sir Geo. Hampson's " Moths of India " contains some 

 valuable information regarding structui'al points. Mr. Warren's 

 papers in the " Nov' itates Zoologicae " are indispensable for 

 i-eference, but must be used with caution. To Mr. L. B. Prout, 

 who has lately undertaken an examination of this subfamily for 

 the "Genera Insectorum," I am much indebted for information 

 regarding some exotic genera, and for the right understanding of 

 the genera Comostola and Leucestkes; also for sending me types 

 of some of the Hiibnerian genera. As my tabulation of the 

 genera is necessarily, to some extent, artificial, I have attempted 

 to illustrate their natural relationships by means of a " genea- 

 logical tree." Such a device, though useful, can be at best no 

 more than a rough approximation to the truth; and a 

 knowledge of the exotic genera, which I do not possess, would 

 probably entail considerable modification. 



Following Mr. Meyrick, the lengths of the palpi are expressed 

 in terms of the breadth of the eye, the lengths of their terminal 

 joints in terms of the second joint, and that of the antennal 

 pectinations or ciliations in terms of the breadth of the antennal 

 stalk. The numerals following records of locality refer to the 

 months of capture. A f is attached to the names of species, 

 whose structure I have not been able to examine. 



I am, as usual, much indebted to Mr. Geo. Lyell for the loan 

 of specimens from his extensive collection, and for many locality- 

 references.
