fers in that the punctures, from a certain ]3oint of 

 view, appear to be situated behind and against a 

 continuous serrate finely raised line, an appearance which 

 seems to be caused by the jDunctures being more deeply im- 

 pressed at their front than at their hind end. I suspect that 

 the slight canaliculation of the pronotum in the type may 

 not be a constant character.
