Closely allied to the preceding species, B. mcmhranaceus, but 

 differing principally by the lateral margins of the sixth abdominal 

 segment being sinuate, somewhat rectangularly excavate ; tlie 

 pi'onotum is also relatively narrower than in B. membranaceus.

Dr. Bergroth informs me that although the males ai*e easily 

 distinguished from B. membranaceus., the females are only to be 

 separated by a difference of genital segments. 



B. Pronotum only modxratehj sinuate before base of scufelhim. 

 a. Anterior angles of pronotum not lohately produced.
