JSASPBEEEY BEETLE. 89 



Presumably a little search into the cause of damage would have 

 shown plenty of " Easpberry maggot " present at other infested 

 localities, but no other specimens of this part of the attack were 

 sent me. 



Prevention and Eemedies. — The most available method appears 

 to be shaking off the beetles in such a manner that they may have no 

 chance of escaping and flying back to the Raspberry blossoms, and no 

 better plan appears to be mentioned anywhere than that mentioned 

 by Mr. Wise at p. 87, of shaking the infested bushes over bags soaked 

 in paraffin oil. Anything (as for instance, cloths, tarred boards, or 

 baskets tarred inside) into which the beetles would fall, and from which 

 they could not escape (whether from being poisoned or stuck fast), 

 would answer well. But in any case the operations should be carried 

 on early in the morning, or when the beetles will be dull and sluggish. 

 " On hot days these little beetles fly away directly they are alarmed." 



If it were possible to have the fruit, which from its ruined condition 

 is noticeably infested by the maggots, gathered and burnt, this would 

 save much recurrence of attack. The only other available methods of 

 prevention appear to be — Istly, so clearing away all old wood, and 

 places in which the chrysalids may be sheltered, that they may thus 

 be got rid, or, to a great measure, got rid of at the bushes. But, 2ndly, 

 though I do not see this plan has as yet been brought forward, it 

 seems not unlikely that, as these little chrysalis-cases are stated to be 

 formed in crannies under the bark, or in the wood of the Raspberry- 

 stems, there may be many hidden about the bearing-stems of the past 

 season which are regularly cut away in course of ordinary treatment. 

 If so (unless these trimmings are destroyed), the beetles which come 

 out from them in spring would be a most fertile source of infestation 

 to the neighbouring blossoms. As in any case the old bearing wood 

 must be cut away, it would add little to expense (where this is not 

 already practised) to burn it, and it might be that this would strike at 

 the root of much further mischief. 



Red-bud Caterpillar. Lampronia rubiella, Bjerk. 



The mischief caused by this attack may be readily known from 

 that caused by the Bytunis beetle and its maggot, mentioned in the 

 foregoing paper, by reason of it affecting the inside of the young buds, 

 or shoots, or pith, whilst the beetle attacks the Raspberry blossom, 

 and the beetle maggots afterwards are to be found in the fruit. 



The " Raspberry-bud " moth caterpillars are about a quarter of an 

 inch long, of some shade of red, with black head, and black mark on
