562 MONOGEAPH OF THE AUSTRALIAN CICADID^E, 



found extending over a very large area, reappearing in widely 

 separated districts if the class of country they frequent is similar. 

 Thus Tibicen ivillsi, described by Distant from the neighbour- 

 hood of Rockhampton (from which we also have received it), is 

 found at Bourke, N.S.W., ranging up the Queensland Coast to 

 Townsville, and reappearing at King's Sound on the North-west 

 Coast of Australia. Mehwijjsalta annulata ranges from the 

 western towns of Wagga and Narromine, N. S. Wales, to Towns- 

 ville, N. Queensland. The appearance of members of the genera 

 G(Bana and Huechys is interesting as showing the relation of our 

 forms with those of the Indo-Malay region. 



This paper contains descriptions of all of the Cicadidai known 

 to us to inhabit Australia, numbering 119 species included in 21 

 genera. The greater number are in the various collections here; 

 but a few are unknown to us, although most of the types are 

 still preserved. In the National Museum, Melbourne, are several 

 of Walker's species determined by him; these, however, are of 

 little value because the same name is given to distinct species. 



Owing to the great number of species in the genus Melampsalta, 

 we have separated the new genus Pmiropsalta, from which it 

 differs principally in the presence of five apical areas in the wings, 

 there being six in the old genus. Eventually those species having 

 the ulnar veins distinct, but contiguous, must be separated from 

 each genus, while another good generic character is the presence 

 of a spine above and just before the apex of the anal appendage. 



Our best thanks are due to Messrs. J. A. Kershaw, of the 

 National Museum, Melbourne; C. French, Government Entomo- 

 logist, Melbourne; J. G. O. Tepper, Entomologist, Adelaide 

 Museum; Henry Tryon, Government Entomologist, Brisbane; 

 George Masters, Curator, Macleay Museum, Sydney; A. Simson, 

 Launceston; R.Illidge, Brisbane; C. W. De Vis, Brisbane Museum; 

 and A. M. Lea, Government Entomologist, Hobart, for the loan 

 or gift of material, and other courtesies. 



Our collection, containing many of our types, is temporarily 

 deposited in the Macleay Museum, Sydney.
