The three described species of this genus occur within our limits, whence two others 
are now added. ‘They may be separated thus :— 
a, First antennal joint extending to far beyond the apical process of the head, 
the post-ocular portions of which do not extend outwards beyond the 
prominent eyes. 
a', Anterior pronotal angles very prominent in front, subacute, coarsely 
crenate externally; post-ocular portions of the head dilated into a 
short tooth; venter finely punctured. 
a", Body oblong and widening behind (¢), oblong-ovate (?); corium 
rounded at the apex er 
b". Body elongate-triangular in both sexes; corium obliquely truncate 
at the apex . 2 1. wee we wee ew ew ee.) Subtruncatus, Bergr.
