L. foveolatus and L. punctulatus have apparently caused much trouble in their 

 identification, and this is only possible after an examination of a good series, more 

 by an exercise of judgment than by any well-defined differences. 



In the present species the antennae and tarsi are conspicuously pale, in L. punctulatus 

 they are rather ferruginous or pale brown ; in L. foveolatus the specimens are never 

 three times as long as wide, while in L. punctulatus the length is in that proportion. 



As usual in black species there is a tendency in the elytra to become castaneous, 

 inclining more or less to red. When this occurs in L. foveolatus the colour is limited 

 to a broad band including the suture, leaving the sides of the elytra black. 



5. Lissomus ustulatus.

This species has often the greater part of the elytra red, the sides, base, and apex
