Obs. —This genus belongs to the Schonherrian subdivision, cohors and 
tribe of the Eugoni, to which it is somewhat similar in form, but its 
antennae have the two terminal joints of the funiculus short and wide, con¬ 
nected with the club, which is, when regarded separately, shorter and 
wider than in that genus, with the joints transverse and connected; the 
head is somewhat extended behind the eyes; the rostrum is not narrowed
