The short rostrum which is not triangularly dilated at the tip, tlie dentate 

 pygidium which is greyish yellow and has a brown middle line, the non-dentate last 

 ventral segment, the three pronotal lines which are not abbreviated in front, and the 

 absence of a short transverse spot before the declivous ape.x of the elytra, distinguish 

 this species from its allies.
