_ A widely distributed genus including numerous species, one at least of which is 
cosmopolitan. The two new forms now added differ from Dr. Reuter’s definition of 
Piezostethus in having the apical half of the scutellum and the greater part of the 
elytra opaque, and the apical two joints of the antenne a little stouter than usual. In 
one of these species the anterior trochanters are armed with a short tooth in the male.
