122 Insect Pests. 



wind break it off. The description of an attack very similar to this 

 by a weevil was sent me some years ago from Surrey, and as the 

 imagines are found on apple, it is possible it may have been due to 

 them. 



Obrium canthaeixum, L. {ferrugineum, F.). — This species is found 

 in the bark of apple trees, but is rare. It is an elegant beetle about 

 I inch in length; it is elongate, of a pale reddish-brown colour, 

 with dark brown antennae and legs ; eyes very large and black, 

 wider than the thorax ; antennae much longer than body ; elytra 

 depressed and punctured. According to Dr. Power, who bred them 

 from aspen, the beetles kept on coming out from the same piece of 

 wood for three years. 



PoGONOCHJjRUS BiDENTATUS, Thoms. — Also found under the bark 

 of decaying apple and pear trees. This is a fuscous beetle, variegated 

 with white, and ligher or darker brown pubescence ; base of antennal 

 joints white ; elytra narrowed at the apex, which is broad and biden- 

 tate, scutellum clothed with white pubescence ; at the base of the elytra 

 is a broad band of white pubescence, a little cloud at the shoulder, 

 and in the middle, extending from the base over nearly half their 

 surface, between this and the apex, are several black spots of hair ; 

 legs dark, variegated with red, more or less pubescent. 



According to Canon Fowler, from whose work the description of 

 the beetle is given, it is local, but not uncommon in many districts. 

 I have never met with the species myself, and do not think it has ever 

 occasioned any harm. 



THE APPLE SAWFLY. 



(Hoplocampa testvdinea. Klug.) 



The Apple Sawfly is very persistent in some districts of Britain. 

 To some extent its method of working resembles that of the Codling 

 Moth, so much so that it has often been confused with it. It has 

 been known as injurious since 1847, when Westwood (1) described 

 an attack from personal observations. The insect was first described 

 by Klug (Berl. Mag. viii. 60.30). Ormerod refers to it in her little 

 handbook on Orchard and Bush Fruit Pests (2). The larvaj can at 

 once be told from those of the Codling :Moth by the presence of six
