Diagnosis. Members of this genus can be distinguished from those of other broscine genera in the region by the following combination of character states: body size large, BL> 15.0 mm; head with one pair of supraorbital setae, vertex with shallower, broader, and distinctly punctate transverse sulcus between tempora; genal ridge present, extended from posterior region of head to ventral margin of eye; gula without deep transverse grooves on either side; maxillae with two setae on eustipes; mentum with one pair of setae; submentum with three pairs of setae; antennomere 3 with apical whorl of fixed setae only, antennomere 4 with or without pubescence on apical one-half; pronotum with basolateral setae present; elytra with parascutellar setae present; male protarsi with tarsomeres 1 to 3 with ventral pads of adhesive setae, all male mesotarsomeres lacking ventral pads of adhesive setae.

Diversity and geographical distribution. This genus includes 25 described species and two additional subspecies ( Häckel et al. 2010). Its geographical range extends across the Palearctic Region, from the Canary Islands eastward to Japan. A single species, B. cephalodes (Linnaeus) , is adventive in eastern North America (Cape Breton Island and Prince Edward Island in Canada) ( Larochelle and Larivière 1989).
