Rhynchophoroiis Coleoptera of Japan. 07 



genus Otiorliynchuis. It is^ in fact, all that has been 

 discovered in Japan to represent the great genus that 

 has several hundred species in Europe. 



OTIORHYNCHID^ ALAT^. 



The Japanese species of this division are not very 

 numerous, but it is probable that a good many others 

 remain to be discovered. 



There is but little difficulty in distinguishing- the 

 genera. These are eleven in number, and may be 

 tabulated as follows : — 



Prothorax without ocular lobes or vibrisste. 

 Claws connate. 



Scrobes visible from front. 



Rostrum with prolonged front angles . . Diallohius. 

 „ simple, as usual at tip .... Phyllohius. 



Scrobes entirely lateral Scythropus. 



Claws free. 



Scrobes widely separated. 



Antennae longer than the body .... EumyUocerus. 

 Antennse not longer than the body. 



Second joint of antenna? short . . . Macrocorynus. 

 „ ,, „ long .... Myllocerus. 



Scrobes separated on upper surface by only 

 a small space. 

 Rostrum with a recurved process at tip . Anosiinus. 

 „ without ,, ., „ . Hyperstylus. 



Prothorax with vibrissas or ocular lobes. 



Prothorax Vith vibrissse but not lobes . . . Chlorophamts . 

 „ without vibrissas, but with lobes. 



Rostrum rather slender, broader at tip . . Phytoscaphus. 

 „ thick, not broader at tip .... Canoixus. 



Phyllobius, Germar et Auct. 



The Japanese species of this genus appear to be 

 numerous, and I have no doubt others will have to be 

 added to those here mentioned. 



The species are far from being closely allied to those 

 found in Europe, though the existence of the genus 

 in Europe and Japan, and its representation in each of 

 the two provinces by numerous species, is the chief 

 character that could be cited as evidence of an affinity 

 between the Otiorhynchid ftiunaD of Europe and Japan.
