This species is very closely allied to B. exesvs. It is very de-

 J. Mease recently exhibited to me some sections of limbs of the 

 Silver pine {Finns sfrobus) trees, which decorate the public 

 .H<-juares of this city, now discovered to be seriously injured by 

 the attacks of this insect. r 258 1
