The distribution of the various groups within the States would 

 probably repay investigation, but the data available to me are 

 too scanty for more than generalisation. 



South Australia contains the greater number of species of 

 Groups i.j ii., and v., and one or two examples of Group iii. 



Central Australia has only an aberrant Subgroup of Group ii., 

 so far recorded. 



Western Australia has mostly representatives of Group ii., but 

 a single species of Group i. occurs on the western seaboard, and 

 also a representative (at present undescribed) of Group v. 



Victoria has representatives of Groups i., ii., iii., and v. As 

 noted above, the Mallee-fauna, which is characteristically South 

 Australian, differs from that of the mountain-ranges and coastal 

 districts. 



Tasmania — Two species have been described, both also found 

 in Victoria, one a member of Group i., and the other of Group iii. 



New South IFa/es.— Group i. is represented on the southern 

 highlands; Group iii. along the whole length of the mountain- 

 chain; and Group iv. on the tablelands, especially in the southern 

 half of the State. Group v. is represented by one species at 

 Mt Kosciusko, and another in Riverina. 



Queensland. — Only two species have been described from this 

 State S. meliceps Pasc, I am unable to place, while *S'. queens- 

 landicus is an aberrant member of Group v. 



It may be well to point out that the Amycterid fauna of the 

 vast district lying to the west of the Darling, and of similar por- 

 tions of Queensland, is quite unknown. The Northern Territory 

 and North-West Australia also have never been searched for 

 these insects, although I do not think that the genus will be 

 found to extend to these regions.
