554 NOTES ON AUSTRALIAN COLEOPTERA, 



one arrives at the result that P immaculatus, inter alia, has the 

 prothorax more strongly lobed behind than P. australis and the 

 elytra punctured as in that species. I have examples of an insect 

 (from S. Australia) which presents these characters and which no 

 doubt is P. immaculatus, P. occidentalis has the prothorax lobed 

 hindward not more strongly than P. australis, and the elytra con- 

 siderably more strongly and less closely punctured. It is the only 

 species of Philophloaus yet reported from Western Australia except 

 P. Froggatti, Mad., (from King's Sound), which is a black species 

 with well defined vittpe on the elytra.

This species is much like P. tichei^culatus, Macl., (of which I owe 

 a fine example to the kindness of Mr. T. G. Sloane of Sydney 

 whose determinations of Australian Carabidce can I believe be 

 thoroughly i-elied on, he having made an especial study of them ; 

 the example in question agrees very well witli Sir W. Macleay's 

 description). From P. tuberculatus the present species differs 

 chiefly as follows : — (a) the elytra are narrower in comparison 

 with the prothorax, being by measurement actually (about as 11
