XLIII. Acm/F.ops Lec. 1850. (Gr., "point + eye.") 



Species of small or medium-size, having the eyes small, not 

 emarginate; antennas about the length of body, the fourth joint 

 slightly shorter than third ; thorax variable in form, the disk either 

 distinctly angulated or rounded, not tuberculate. Many of the 

 species vary much in color, so that the synonymy is very much 

 mixed. But two species have been taken in the State, though three 

 others perhaps occur.
