There is another large group of snout-beetles, some mem- 

 bers of which are very numerous in Minnesota, that deserve a 

 passing notice, and the description of a few injurious ones will 

 be given, which, with the illustrations, will give a general idea

The Potato-stalk Borer ( Trichoharis ynotata Say) is 

 fairly common. It is a small ash-gray snout-beetle, about one-
