the tender egg by a vigorous and rapid growth of the tip of the 

 cane. 



The methods of combatting this insect are simple but they re- 

 quire prompt attention. As soon as the tips of the canes begin 

 to droop they should be cut off below the point were they are 

 girdled. In this way be larva can be destroyed before it has be- 

 gun to bore into the lower portion of the cane, and thus only the 

 tip of the cane will be lost. When, however, the first indication 

 of the presence of this pest is the dying of the entire cane caused 

 by the boring of the larva, as was the case in our experience nar- 

 rated above, the infested canes should be promptly cut out and 

 burned. These canes can be readily recognized by the dying of 

 the leaves and by the small holes in them described above. They 

 are most likely to be observed at the time of the blackberry har- 

 vest. It is of the utmost importance that the cutting and burn- 

 ing of these canes should be done promptly. For if it be delayed 

 till autumn, the larvae will have penetrated the roots and will 

 then be beyond the reach of the pruning shears. As illustrating 

 the practicability of this method of combatting this pest, I will 

 state that, doubtless owing to the thoroughness with which we 

 removed the infested canes from Dr. Caldwell's place, two years 

 ago, not a single infested cane could be found last year or this. 



THE SNOWY TREE-CRICKET. 



Oecanthus niveus. 

 Order OrthopteRA ; family Grylud^. 



Numerous punctures arranged close together in a logitudinal series in the 

 canes of raspberry and blackberry and each containing a long cylindri- 

 cal egg. 



Many letters have been received at this office asking for in- 

 formation regarding injuries of a peculiar nature to the canes 

 of raspberry. One writer, an ' extensive grower of raspberries, 

 speaks of the attack as a sudden one, and says that the entire 

 destruction of his plantation is threatened. Although we do not 

 consider the matter so serious as indicated by this experience, the 

 many inquiries regarding it show that the insect causing the in- 

 jury is worthy a description in this place, notwithstanding it has 

 been frequently described in entomological reports.
