OTIORRHYNCHINA. 
This tribe contains a large number of species, the majority of which 
belong to the very extensive and important genus Otiorrhynchus, which 
is very largely represented in Europe, and contains some of the most 
conspicuous of our British Rhynchophora: they are most closely allied 
to the Brachyderina, from which they chiefly differ in the formation of 
the scrobes and the club of the antennez ; the following genera occur in 
Britain :— 
I. Throat without special striation. 
i. Scrobes superior, entirely visible from above; 
antenne long. 
1. Femora claviform, often dentate beneath; 
tarsal claws free, equal . OTIORRHYNCHUS, Germ. 
2. Femora not claviform, always simple beneath. = 
tarsal claws variable, connate in our species . . PERITELUS, Germ. 
ii. Scrobes entirely or partially lateral, deep and 
directed towards the eyes; form short, stout and 
robust ; antenne short and thick. 
1. Scape of antenne gradually thickened from 
base to apex ; ventral segments of abdomen clothed 
with dull scales . . TRACHYPHLEUS, Germ. 
2. Scape of antennz strongly ‘thickened and 
produced into a prominence externally at 
base; ventral segments of abdomen without 
scales. . . CATHORMIOCERUS, Schinh.

This is one of the most important genera of the Rhynchophora; it 
contains, at present, about four hundred species, of which the great 
majority are found in Europe and the adjacent countries, the largest 
number, being attached to mountainous districts; a certain amount are 
found in Northern Asia and North America, but the North American 
species (O. sulcatus, ligneus, rugifrons, maurus and monticola) have all
