200 THE GENERA AND SPECIES OF AMYCTERID.E, 



(Trans. Ent. Soc. Lond., ser. 2, vol. III., p. 75.) " The Aus- 

 tralian Curculionidae with a six-jointed funiculus to the antennae 

 including the genera Euomus Mythites (Acanthomus Grerm.) 

 Tetralophus, Wat. Amyeterus and Acantholoplms, form a very dis- 

 tinct and natural group, which might be called Amy der idee.'''' 



M. Lacordaire subdivides the Amy der idee into Amy derides 

 vrais, or those with the scape of the antennae passing the eyes, 

 and the Euo7nides in which the scape of the antennte only reaches 

 the eyes. 



In the present Paper I will confine myself to the first of 

 these subdivisions. 



The Amyderidce verce constitute by far the most numerous 

 subdivision of the group. 



I have found it necessary to add three genera to the four 

 previously described, as the following synopsis will show : —
