As pointed out by Sars, and earlier by Miers himself, 

 though the latter did not regard the distinction of generic 

 value, this genus is separated from Glyptonotus by the im- 

 portant character that it has the side-plates distinctly defined 

 on six segments of the pereeon, from the second to the seventh, 

 while in Glyptonotus they are only defined on the last three.
