striated. It is about one-tenth of an inch long. It is cylindrical and 
uniform light brown; its body is covered with a fine silky pubescence.

less hairy than that of the cigarette or tobacco 
beetle, as a comparison of figures 53 and 55 will

its habits of feeding on almost all drugs found in 
pharmacies. It isa very general feeder, attacking 
a great variety of stored foods, seeds, and other 
materials, and has been said to “eat anything ex- 
cept cast iron.” It is frequently found in store- 
houses and granaries in all parts of the world.
