738 NOTES ON AUSTRALIAN COLEOPTERA, 



hind ward. From S. australis this species may be known by its 

 still narrower and more parallel form, the well defined outer 

 impression on either side at the base of the prothorax, the con- 

 tinuous concavity of outline all across the base of the pro thorax, 

 the somewhat finer striation of the elytra the outer interstices of 

 which are less narrow and convex behind, &c., &c. From both it 

 differs in the distinct though very minute tooth-like prominence of 

 the external apex of the basal keel-like line of the elytra, and its 

 much more nitid surface. 



Mulwala, N.S.W. ; taken by Mr. T. G. Sloane in refuse from a 

 flood in the Murray. 



N.B. — It is possible that this may be identical with S. elonga- 

 tus, Chaud. That species however is described as having an iride- 

 scent reflection, and in any case I do not think its name can stand 

 as it has been given by the Baron de Chaudoir himself to two 

 species in other sections of Feronia.
