One spécimen, lake Superior : bas the appearance of Limonius, 

 but the front is not margined anteriorly, and not quadrate : its rcal 

 afiinities are with thetwo preceding species (1), from M'hicli it dif- 

 fers by its more convex and coarsely punctured thorax. The elylra 

 are somewhat obliquely narrowed posteriorly and more strongly 

 margined than in the two preceding. The first joint of the farsi is 

 not longer than the second.

 angulis anticis rufescentibus latins marginatis, angulis posticis
