Southern half of State : common in meal, grain and other vege- 

 table products. Hibernates. February 2-Xovember 22. Both this 

 and the next species are commonly known as "flour beetles" or 

 "flour weevils." and "live upon cereal and other seeds and various 

 other stored products, but generally prefer flour and meal and the
