The west African form, B. vollenhovenii (Herklots) is no more than 

 a subspecies of B. jamaicensis. It differs only in the slenderer second 

 pair of feet, the carpal and meral joints of which are subequal. The 

 relative lengths of the rostrum and the antennal scales and peduncles 

 agree with those in some specimens of jamaicensis. The two forms are 

 considered identical by Dr. Ortmann. 



According to Dr Edward Palmer, B. jamaicensis is much eaten at 

 Colima, and is offered in the market there as a choice article of food, 

 especially on Fridays and Sundays.
