The Raspberry Beetle. 



about a sixth of an inch. As soon as the flowers open the 

 beetles, as already noticed, feed upon them, and deposit eggs 

 singly deep in a blossom, often just as the bud is opening. The 

 larva is of a dull yellow colour, with brown markings, though 

 the colour varies somewhat, and some specimens are almost 

 grey. It has six jointed legs in front, and two pointed curved 

 spines behind. The maggots are full-grown about the time the 

 fruit is ripe. They are then about a third of an inch long, and 

 a cylindrical process acting as a proleg may be noticed beneath 

 the last segment. When full grown they leave the fruit and 

 crawl to some shelter, such as crevices in the poles, under the 

 rough rind of the canes, or the earth around the stocks. There 

 they pupate and remain all the winter, the beetles emerging in 

 the spring when the flower-buds are bursting. 



When large numbers of the beetles are noticed about the 

 raspberries in May or early June, it would be well to go over 

 the beds, holding a tarred sack or boards on each side of the 

 rows, and jar the beetles on to them. This should be done on 

 dull days, as the beetles are very active in bright sunshine, and 

 would fly some distance. 



All prunings and rubbish should be burnt in the winter, so as 

 to destroy pupae ; the old bearing wood should always be burnt. 

 In the early spring paraffin and ashes might be hoed into the 

 ground near the stocks. 



Hints on the Selection of Portions of Diseased 

 Plants Intended for Investigation. 



Mutual disappointment on the part of sender and receiver 

 is too often experienced, when plants, supposed to be diseased, 

 are submitted for examination. Principal among reasons for 

 this state of things, are one or more of the following : — 



1. The fragmentary nature of the material sent for investiga- 

 tion. 



2. Lack of care in transmitting ; the specimen arriving 

 shrivelled or dead. 



3. Absence of information as to the conditions under which 

 the plant grew.
