Note. — In connection with the subject of this paper, the 

 following fact is of some interest : — In 1873 two scolytid enemies 

 of Scots pine new to the British fauna were found in some 

 pit-props at Dukinfield, Cheshire. Enquiry was made as to the 

 locality in which the pit-props had been grown. It was naturally 

 inferred that they were foreign-grown. No definite information 

 could be obtained, but men working at the pits expressed the 

 belief that the wood was Scottish-grown, as they did not like to 

 use foreign-grown timber — it was not so lasting as Scottish-grown 

 (v. Ent. Mo. Mag., vol. x., p. 209).
