Elytra slig-htly longer tlian the thorax, shining, the apical 

 half yellow ; in front of this infuscate, but the extreme base 

 reddish ; along the suture with a row of punctures, and

This species greatly resembles the foiu- preceding ones 

 (deletum, pictum, intef/ricm and liilare), but is a little 

 larger, and may be easily enough distinguished by the 

 more even distribution of the punctures on the head.
