A mutilated specimen from Oregon. The tarsi , so far as 

 ears be distinguished , belong to the present genus , and the 

 characters are thore of the preceding species : the sides of the 

 thorax are less reflexed posteriorly, and the antennae are somewhat

Allied to this species appears to be Elater ruflfrons Randall

 lary coloured , but is much larger (6'" ). It was found in 

 Maine.
