Arizona. 



This insect might be taken for a genus near Pachnxus, but a close study has caused 



me to place it in the group of Naupactides (according to Lacordairc), following Sitones 



and Pandeleteius, with which it presents a few characters in common. Its size is 



very large and it resembles somewhat a Cleonus. It is of a very brilliant black, covered 



with dark gray squamules, very lightly rosy on the elytra when viewed in a certain 



aspect.'
