1914 ENTOMOLOGICAL SOCIETY. 51 



Buffalo Tree-hopper (Ceresa hubahis). Specimens of apple branches 

 severely attacked by this insect have been received from time to time, but appar-' 

 ently there is no special increase in its numbers. 



Capsids. Fewer complaints than usual of injury to fruit have been received. 

 An exception should be noted of some badly deformed apples forwarded from the 

 office of the district representative at London, with the statement that the whole 

 orchard was affected in the same way. I hope, if possible, to visit this orchard 

 next spring and determine the species responsible. ; 



Apple Tree-borers. From St. Joseph's Island and the adjacent mainland 

 there are complaints of serious damage from borers which attack both nursery and 

 orchard trees. These and winter injury are the two great foes to the fruit industry 

 in those parts. I was not able to obtain specimens either of the larvae or adults 

 but was informed that both the Flat and Round-headed species were at work. The 

 presence of so much forest may be the explanation of the greater degree of injury 

 in these parts. 



Bud Moth (Tmetocera ocellana). The effect of our ordinary methods of 

 spraying apple orchards upon the control of this pest was excellently illustrated 

 by two orchards south of Hamilton. One of these has been well sprayed three times 

 each year for several years and scarcely any bud moth larva} could be found; the 

 neighboring orchard about 200 yards away is neglected and is very severely 

 attacked, worse than I have ever seen an orchard before. 



Cherry Fruit Flies (Rhagoletis cingulata and R. fausta). These flies though 

 moderately abundant were not so numerous as in 1912. We have not yet been able 

 to determine how widely they are spread throughout the province, but have proven 

 that they are to be found all through the ISTiagara district and are much more 

 destructive than has been supposed . We have worked out their life histories and 

 means of control with the exception of a few minor points. Next year we hope to 

 give a full account of them. 



Shot-hole Borer or Fruit Tree Bark Beetles {Eccoptogaster rugulosus). 

 This species of Ipidae seems to be on the increase again. A peculiar or to me new 

 form of injury from it was the destruction of the terminal part of numerous twigs 

 on Sweet Cherry trees near Fontliill. At first sight I felt sure from the dead 

 leaves that the trouble must be due to Brown Eot, but an examination showed that 

 the beetles had bored into the twigs and caused the death of the part beyond. 



European Bed-Spider {Tetranychus pilosus). For some time I had sus- 

 pected that a good deal of the so-called Bed Spider work could not have been 

 caused by Tetrojiychus himaculaius. Specimens of the mite were captured and 

 sent to Mr. Nathan Banks who at first thought they must be the Southern Bed 

 Spider {Tetranychus mytilaspidis) which had escaped from citrus plants in the 

 greenhouse, but on my sending him more material he identified them as the 

 European species, not hitherto reported in North America. This species is most 

 common on European plums but is also found on apples. It probably occurs on 

 many other kinds of fruit trees also though I am not sure of this. I have found 

 it on plums from Forest to Bowmanville, and from Guelph down to Fonthill, so that 

 it is very widely spread and must have been in the province many years. It is I 

 believe more destructive to plums than the ordinary red spider, being apparently 

 much more abundant on these.
