This genus comprises two small speeies. one of which was de-

L*128 (4027). Tharops ruficoknts Say, Journ. Phil. Acad. Nat. Sci., Ill, 

 1823, IGG; ibid. II, 107, 026. 

 Subcylindrical, slender, slightly narrowed behind the 

 middle. Piceous black; elytra usually with an elongate, 

 triangular sutural yellowish space. Antennje and legs 

 reddish-brown, the former not passing the hind angles 

 of thorax; those of male with joints 4 to 10 each fur- 

 nished with a branch as long as the entire anteiniii'. 

 eleventh joint as long as the branch of the tenth, but
