described by Heller, that the smaller anterior opening is a definite 
perforation and not a furrow or fovea, and that it serves for the passage 
of the ventral nerve chord as well as the attachment of the inferior 
retractor muscles. The separation of the occipital foramen into two 
portions by an intervening tentorium would therefore appear to be one of 
the principal characteristics of the larvae of the Prionini; while far from 
peculiar to the group this feature appears to show valuable generic 
characters. 
Text figure I shows the principal characters used in the descriptions of 
Cerambycoid larvae in the present and succeeding Records.
