ACOMPOCORIS, Jeut. 
Very closely allied to Tetraphleps, but recognizable by 
its longer rostrum, which reaches to the intermediate coxa, 
by the sides of the pronotum anteriorly being scarcely re- 
flexed, and by the rather longer first joint of the antenna, 
which just reaches the apex of the cheeks ; according to 
Reuter, the canal of the odoriferous sac is curved forwards 
at the apex instead of backwards. We have both the 
Palearctic species recorded from this country.
