Most of the species of this genus are un- 

 common; S. vespertinus and S. meridianus 

 are the species most frequently met with. 

 S. brunnipes and S, jiavicollis are both scarce ; 

 while the rest of the species occur occasion-

 Head and thorax red ; elytra brown,

 side margin pale. Length, 1^ lines . . 



B. similis. 



Of the species of this genus, several are 

 common and widely distributed, such as B, 

 verbasci, B. harpalinus, and B. similis B, 

 placidus, B. cognatus, and B. distinctus are 

 fairly common, while B. collaris is scarce. 



B. harpalinus and B. similis seem partial 

 to hilly ground, and the latter we take plenti- 

 fully in September and October among dead 

 leaves of heather. B. distinctus I have only 

 taken once, but then it was plentiful in a 

 swamp among rushes.
