mention it to you. It is to place from now (May) on to July heaps 

 of green stuff (lucerne or clover) about the gardens under any rough 

 boards. The beetles may be found there during the day and col- 

 lected. This means trouble, but I believe if we collect the green 

 stuft", say, every week, burn it and replace new, we shall kill the 

 eggs laid by these beetles, for they always seek shelter to deposit 

 their eggs in preference, so if the land is clear and cultivated they 

 fly there to lay their eggs, and so the wire worm are prevented. 



I have known gardens cleared of wireworm by persistent trapping 

 of the larvae by placing " baits " near each " hill." Of all baits there 

 is no doubt beetroot is the best. 



One reason why wireworm are so bad in hops is that much rape 

 cake, nibs or dust is used. This attracts the beetles to the gardens, 

 and only draws the larva) away 'pro tem. I am sure it does more 

 harm by encouraging this pest than good as a manure. 



The use of bisulphide of carbon comes in for wireworm in hops. 

 A quarter of an ounce each side of a hill will kill all grubs, but no 

 one tries to use it because it is highly inflammable, and except used 

 with care may do harm. It has cleared out Phylloxera on vines, and 

 would do just as well for hops for such pests as wireworm and Otter 

 or Ghost moth grubs {Hepialus humuli).

The Cabbage Moth. 



(Mamestra hrassiese^ Linn.) 



Some caterpillars sent by a correspondent from St. John's 

 Wood, N.W., to the Museum, were recorded as doing much damage, 

 they were those of the so-called Cabbage Moth (Mamestra hrasdcm 

 of Linnaeus). 



These larv« are great pests in gardens all over Great Britain and 

 Ireland. It has been one of the notable pests this year in parts of 

 the South of England and has done much harm. Every year it is 

 reported as doing damage, bnl some years moi-e so than others. It is
