DESCRIPTION. 



Body punctured, above black-bronzed, below copper-coloured and glossy. Head obscurely copper, 

 confluently punctured and wrinkled, with a pair of levigated irregular elevations between the eyes ; 

 nose bilobed with divaricated lobes forming an obtusangular sinus ; antenna? copper with a testaceous 

 pedicel : prothorax transverse, confluently punctured with several levigated spaces ; lightly and widely 

 impressed, impressions faintly gilded ; disk channelled ; sides very slightly emarginate ; base with a 

 double sinus : scutellum triangular, acuminated : elytra with the depressed parts confluently punc- 

 tured and very faintly gilded ; with three subinterrupted longitudinal ridges connected by transverse 

 levigated elevations ; the two external ridges become confluent and proceed as a single ridge to the 

 apex ; lateral margin towards the apex minutely serrulate : back of the abdomen of a fine silkv 

 green : underside of the body thinly planted with hoary hairs ; prosternum constricted in the middle 

 and terminating towards the anus in a dilated trilobed point : shoulders much incrassated, armed 

 below with a stout tooth ; cubits clubbed at the apex ; four anterior tibiae bent or bowed : hypopy- 

 gium bidentate. 



This species is the American representative of B. chrysoslogma, to which it approaches very 

 near, but it is considerably smaller; the elytra have only three ridges, and want the two golden 

 impressions that distinguish that insect, and the back of the abdomen is of a different colour. It is 

 also very like B. femorata, but the sinus of the nose is obtusangular, and not at all acuminated ; 

 the frontal tubercles are less elevated, the prothorax is rougher, the ridges and elevations of the 

 elytra are bolder, and the hypopygium is distinctly bidentate.
