The following species are unknown to me, and have been, there- 

 fore, omitted from my Table, as unidentifiable from description. 



*S'. rugosus Boisd. — Mr. Blackburn has apparently attached this 

 name to a small Victorian species (These Proceedings, 1 889, p. 

 1269), but the name has been similarly attached, in some Collec- 

 tions, to a species from New South Wales (which I have from 

 Bathurst); in both cases without any reason, beyond the fact 

 that the few lines of description fit the insect; but there is no 

 evidence, at present, to distinguish it fi^om the common *S'. Icevi- 

 collis Germ. 



>S'. marginellus Hope.— A large tricostate species, with large 

 flat margiris to pronotum and elytra, from Norfolk Sound, appa- 

 rently near *S'. catenulatus Macl. 



* Species identified only from description,
