 a yellowish colour: the casque large, and shaped 

 like a crescent or boat longitudinally affixed by its 

 bottom to the ridge of the upper mandible: it is 

 not concave at the top, but flattened, and the two 

 ends rise up one before and the other behind the 

 base of tlie mandible, that in front somewhat ex- 

 ceeding the length of the other : the legs are short

 according to the account of a Dutch officer, com- 

 municated to Monsr. Levaillant, it frequents large 

 woods, uniting in troops in order to devour carrion.
