 with a distinct transverse depression below the base, more strongly 

 punctured than the thorax, the punctures arranged in three or four 

 more or less regular rows near the suture, much more irregularly so 

 at the sides, the interstices at the latter place transversely rugose,

Hah. Amazons. 



I have retained the specific name given to this species 

 by Lefevre, who compared the insect with his types ; B. 

 abdominalis belongs to the group of smaller-sized species, 

 having an anteriorly strongly narrowed thorax with 

 angulate sides ; the fulvous antenna3, which have the 

 terminal joints only darker, and the fulvous abdomen and 

 legs principally distinguish this species. Two apparently 

 male specimens are before me.
