Queensland, near Ipswich. Dr. Howitt. 



This species comes very near B. Aiistralis and Jiamatus. It 

 differs in size and sculpture, and has not the curved coxae of the 

 posterior legs of the latter species : yet the posterior coxae have 

 a prominent tooth or short thick spine. In their elongated and 

 very convex form, and dorsal teeth on the thorax, these three 

 species form a distinct section of this genus.
