To this genus belong Geot. bilobus Fab. and 

 C. Vesputius Hope. Monsieur Serville seems to 

 attach much importance to the sutural striae as 

 marking some of the genera of Dynastidse ; the 

 striation in the above genus is certainly remarkable. 

 As a generic distinction, however, much weight 

 cannot be given to it.
