Group 7. 



This is composed of species having a strong resemblance to Callidium, but 

 differing in the form of the anterior acetabula ; they would be united to the preceding 

 group, but foi the dilated palpi. The maxillary palpi are always longer than the 

 labial, and the joints of the abdomen nearly equal. From the Chjti this group differs 

 by its porrected head.
