THE INSECTS OF NEW JERSEY. 395 



T. trinotata Say. Throughout the State, locally common and sometimes 

 injurious. The larva is the "potato stalk borer," which eats out the 

 stalk of the plant and prevents the crop from maturing. The beetles 

 remain in the stalks all winter, and if these stalks are raked up and 

 burned when the crop is harvested the entire brood will be destroyed. 

 The native food is nettle.
