468 CLASSIFICATION OF THE RHYNCHOPHOROUS COLEOPTERA. 
in the catalogues. The only connected series of descriptions is 
contained in the synopsis by Dr. Zimmermann, with an appendix, 
nition and distinction of each species. Many of the same have 
been described by Mr. Eichoff,+ with diagnoses only, and no € 
parative or differential characters. For their identification, there- 
fore, comparison of specimens will be necessary, or the complet 
of the promised monograph of the family from the hands of 
author must be awaited.
