Clarence River, N.S.W. (Mr. A. M. Lea); Brigham [? Brisbane]. 



This species resembles very much B. hamatus, but the pro- 

 thorax has no tooth on the sides, the elytra are somewhat shorter, 

 the metasternum is broadly and deeply impressed with a furrow 

 at the bottom of the impression ; the intermediate trochanters 

 instead of having a median tooth as in B. hamalus, are somewhat 

 concave and produced at the apex .externally.
