" Valuable fruit trees •which have suffered injury from fire 

 or frost cannot always be protected from attacks of the borers 

 by coating the bark, because of the risk of injury to the buds, 

 which must be allowed to grow upon the trunks. In such 

 cases if borers enter the wood their holes must be plugged. 

 An excellent method is to insert an iron wire as far as it will 

 go, cut it off, and leave the piece in the hole. The inhabitants 

 of colonies thus imprisoned are unable to extend their borings, 

 and inevitably perish." — (H. G. H.)

Xyleborus saseseni. — 1, beetle ; 2, larva — magnified, with natural length 

 of each ; 3 and 4, cell, natural size, showing broad and flat and also narrow- 

 view. 



Up to the date of the observation made in the early part of 

 the year 1897 of the attacks of Xylehorus saxeseni to the wood 

 of Plum trees, although the presence of this species in England 

 was known of by entomologists, yet (so far as I am aware) 

 there was no record of it having occurred here as a decided 

 orchard pest, and naturally when the injuries were noticed 

 they were at first attributed to the attacks of Xylchor-us dispar, 

 which had caused much mischief in various Plum-growing 

 localities for several years previously, and was first reported 

 (from Toddington, Gloucestershire) in 1889. 



This infestation, however, may have been present, for the 

 chief observable difference in method of injury, which consists
