630 NEW SPECIES OF AUSTRALIAN COLEOPTEaA, 



Hab. — Galston (Lea); Armidale (Mr. D. McDonald). 

 The males are somewhat narrower than females. Notwith- 

 standing their small size I have seen specimens of this species 

 leap 7 or 8 inches; when beaten into an umbrella on a sunny day 

 they are very difficult to capture. I have obtained them only 

 , f rom the flowers of Acacia decurreas. The size of this species 

 will at once distinguish it from R. australis and R. dixtiagnendus.
