786 REVISION OF THE AMYCTERIDES, iv., 



Subgroup D contains those species of Group v., which have 

 the intermediate tibiae with a strong, subapical notch. >S^. tuher- 

 culosus MacL, from Victoria, and S, Qitee^islandicus, sp.n., from 

 Queensland, are larger than the others. Of these latter, S. Ger- 

 mari appears to form a centre around, and from which, several 

 variations occur. I have, however, not considered these as speci- 

 fically distinct, except in the case of S. parvulus and *S'. mucroni- 

 pennis. 



S. mucronatus Macl., and S, meliceps Pasc, should probably 

 also come into Group v., the former being probably a synonym 

 of S. tuberculosus. 



The Group, while on the whole a natural one, tends to lead, on 

 the one hand, through »S'. iyiconstans to the Stutchburyi-group; 

 and, on the other, through S. tuhermdosns and S. Queenslandicus 

 to the subcostatus-group. 



The majority of the species are inhabitants of South Australia, 

 though several extend into Victoria. S. inconstans, S. exilis, 

 and S. Stewarti occur in New South Wales; while S. Queens- 

 landicus is from Southern Queensland. S. meliceps Pasc, is from 

 Central Queensland.
