Note. Here are to be placed, according to ERICHSON, genera 

 jEgialia LATH., and Chiron MAC L. ; they differ however, in the 

 labrum and mandibles being horny ; wherefore they ought to be 

 counted with the preceding section of the Arenicolce as by LATKEILLE. 

 jEgialia is enumerated by WESTWOOD with the Trogidce ; Chiron, 

 on account of a certain similarity of habit, is considered by many 

 to be allied to the Passali.
