A species occurring very commonly in this region above the 

 4,000 feet level. I have 30 specimens before me, all of which 

 have the peculiar elytral sculpture noted above, e.g., strongly 

 sulcate, with the sixth interval broken. The species forms a 

 link between some of the more nitid species, like C. cerijjennis
