 exhibited in Callistus and CaUislomimus^ and, in fact the latter 

 genus is connected with Pristomachaerus by insensible gradations

 that there remains only the prolonged hind angles of the thorax 

 separated from the base by a deep sinuation to distinguish Pri- 

 stoinachaerus.

 the suturai apex of the elytra,
