 the shoulders obtusely angulated : legs moderate : femora incrassated in the

Sitona, as at present constituted, contains two very distinct 

 groups, or probably genera, one of which is characterized among 

 other particulars by having the eyes of moderate size and round, 

 the thorax rounded behind the middle, &c. : — the other by having 

 the eyes very prominent and oblong, the thorax considerably dilated 

 in the middle, the rostrum longer, &c. : — the last group, or the sub- 

 sequent section B., forms the subgenus Charagmus of Schonherr.
