 paratype males of B. impicta var. maculata Davidson and DeLong from 

 the DeLong collection have been examined. The female holotype of

 has also been examined. Additional specimens examined were from 

 Arkansas, Connecticut, Delaware, District of Columbia, Georgia, 

 Indiana, Iowa, Kansas, Maine, Maryland, Massachusetts, Michigan,

 B. arctica Beirne. It is quite variable in color and is generally common 

 throughout its range. It can be distinguished from other species 

 by the shape of the aedeagus (see key).
