of a larger size than the sfenóstomus, and is also rather 
more convex ; but it is to be distinguished from the latter 
chiefly by the greater roughness of the hinder part of the ' 
elytra, the interstitial lines, from the middle to the tip, 
being transversely interrupted or broken into elon 
tubercles, while in the stenóstomus this interruption « th 
lines does not appear till near the tip, and is far less 
obvious even there, than in the Lecóntei. In the form of 
the thorax and elytra these two species are hardly to 
be ciniagecieny from each other.
