 SilpJta opcuiu from which ir differs in being smaller, and proportionally 

 narrower ; the i)rothora\ is longer in proportion to its width, and has an 

 obsolete channel ; the elytra are more distinctly punctured, and besides 

 the ordinary elevation at the termination of the e.xternal ridge, have two 

 smaller ones at that of the other two ridges : the ridge next the suture also 

 is mere elevated at its termination than in .V. opaca, of which in every
