888 CLASSIFICATION OF THE RHYNCHOPHOROUS COLEOPTERA. 
principal types among the Rhynchophora: Bruchides, Anthri- 
bides, Attelabides, Curculionides, Calandrides, Cossonides, Sco- 
lytides and Brenthides. The last cited memoir is occupied chiefly 
with a further development of the classification of the largest of 
these, the Curculionides proper, and in it he proceeds to separate 
as sub-families* Brachycerides, Byrsopides and Amycterides, 
epigeal forms in which the tarsi are not dilated, and not furnished 
with brush-like hairs beneath. Having thus isolated them the 
great mass remaining is divided into

The principal types contained in each of these three grand 
divisions are then characterized in a very clear manner ; but for 
a proper understanding of this system, a vast improvement on 
all that preceded, the reader must refer to the original memoir. 
In developing the arrangement of the tribes represented in our 
fauna, I shall be largely indebted to the views expressed in this 
most valuable memoir of Mr. Jekel. 
There remain to be mentioned two faunal contributions to the 
history of this subject: 
1. A series of remarks by Mr. Suffrian,t in which the German 
species of several genera, not before carefully studied, are more 
fully elucidated, and various criticisms upon Schénherr’s system 
made.t The necessity of a more careful study of the tibie and 
tarsi, almost neglected by Schönherr is insisted on, and an arrang® 
ment s the German genera in groups upon these characters ÍS-
