but I am unwilling without more and better specimens for 

 comparison, to regard it as distinct, especially as I know 

 different individuals of B. ovaius do vary somewhat in this 

 respect. Should these differences prove to be constant in 

 other specimens from the same locality, they may possibly 

 be of specific importance, in which case I would propose 

 for it the name of B. occidentalis. If it is only a variety of 

 B. ovatus, which I am inclined to think is the case, it proves 

 that species to have a great geographical range, as it occurs 

 in New Jersey and Alabama, as well as at numerous widely 

 separated localities in Nebraska Territory.
