A small, shining species, with longer antennae than is usual 

 amongst black-legged species. 



The Australian species of Ftimhs known to me may be tabulated 



as follows : — 



A. Elytra parallel-sided, with shoulders lightly rounded. 



a. Appendages black or almost so. 



h. Elytra with pale clothing about suture and apex adeps Oil. 



bb. Jllytra without pale clothing there. 



c. Postmedian markings rounded niceonotatua, n.sp. 



cc. Postmedian markings transverse aUiomaculat^ia y[&c\. 



aa. Appendages more or less reddish. 



rf. Clothing nowhere black exulans ^r. 



dd. Clothing partly blackisii.
