 P. depressus, F., is found under bark, especially of oaks, and has 

 not yet occurred in meal in granaries ; it is generally distr-ibuted in 

 Europe, but has not yet been found in Britain. 



P. ratzeburgi, Wissm. { = P.dej)ressus, Brit. Coll.) has been found 

 under bark, but is commonly found in granaries and bakehouses ; it 

 has been taken in various localities in Britain, and is widely distributed
