Lethierry and Severin (Cat. Gen. H^m. fc. i. p. 166) have 

 queried this species as a synonym of Nezara sparnia^ Dall., 

 probably misled by Walker having differentially referred to 

 that s[)ecies, with which, however, it has nothing in common.

Lethierry and Severin [supra) have regarded these two 

 species as being synonymic. In B. spinosus the pronotal 

 spines are slightly recurved backward ; in S. humeralis they 

 are directed moderately forward and somewhat upward. 

 In all the specimens of this species which I have examined 

 the reddish s])Ot is present at the base of these spines.
