with a whitish spot on each elytron placed almost as in 

 Hydronomus alismatis, Marsli. The shape of the prothorax is 

 almost as in B. inceratus, but its sides are less rounded and the 

 constriction is further from the front margin. The sculpture of 

 the elytra is almost exactly as in B. suhcarinatus, Crylh, except 

 that the strise are less distinctly punctured, but their outline is as 

 in B. inceratus.

albidis sparsim (? exemplo typico abraso) vestitus, pedibus 



antennis (harum parte apicali excepta) et rostri apice rufes- 



centibus ; rostro (exempli typici) quam prothorax sat 



breviori subtilissime punctulato ; capite subtiliter ruguloso 



inter oculos profunde sulcato ; prothorace crebre subtilius 



punctulato vix transverso pone apicem sat fortiter constricto, 



late leviter canaliculato ; elytiis subtilissime rugulosis, 



punctulato-striatis, interstitiis convexis (alternis quam cetera

The deep excavation (with strongly elevated sides) of the 



prosternum and the rounded intercoxal process of the abdomen are 



noticeable characters of this insect. The anterior four tibiae are 



denticulate within.
