636 REVISION OF AUSTRALIAN LP^PIDOPTEKA, IV., 



approximation of vein 5 of the hindwings to 6 is present to a 

 slight degree in several genera, and in the genus Dasyhela is as 

 strongl}^ marked as in the Geometrinoi. Nevertheless they form 

 a natural group and ma}^ conveniently be kept separate. In the 

 neuration there are but few variations, and some of these, such 

 as the separation or stalking of veins 6 and 7 of the hindwings, 

 are not of generic value, being sometimes variable in closely 

 allied species or even the same species. The structure of the 

 posterior tibise of both sexes and of the $ antennae gives trust- 

 worthy generic characters, and I am satisfied that without 

 making use of these it is impossible to classify this subfamily in 

 a natural manner. 



I have 74 species of this group in m}^ collection, and have 

 examined all the species in the collection of Mr. Geo. Lyell, 

 together with all the types in the British Museum, and the 

 great majority of those described by Mr. Warren, Dr. Lucas, and 

 Mr. Lower. Sir Geo. Hampson has helped me in the naming of 

 species of the Anisodes group received by me since my visit to 

 England. 



While the Sterrhince are represented in temperate regions, 

 they are more abundant in the tropics. In Mr. Meyrick's 

 revision, published in 1887, 32 species were ascribed to 5 genera. 

 The present revision contains 102 species ascribed to 20 genera. 

 Some of these are, however, only imperfectly known, and the 

 number of unrecognised species is still considerable. When the 

 tropical parts of Australia are adequately explored man}'^ new 

 species will be discovered. 



I have followed Mr. Meyrick in dividing the genus formerly 

 known as Acldalia Treitschke, into several genera of which Eois 

 Hb., and Leptomeris Hb., are the most important.
