 and has injured the cotton-growing industry of that region 

 more than any other one factor, and the Alfalfa-weevil, 

 also an importation, at present confined to some of the 

 Rocky Mountain States, but a menace to the alfalfa crops

Calandridce. The Bill-bugs, as the Calandrids are com- 

 monly named, include fewer species than the preceding 

 family, but some are quite important. The most familiar 

 examples are the common Granary-weevils, small, slender, 

 brown beetles with rather prominent snouts curving for- 

 ward and downward from the heads. These are every- 

 where found in stored grains. There are two species, one 

 being called the Rice-weevil, but they are similar in ap- 

 pearance and habits.
