148 COLEOPTEEA OR BEETLES. 



about eighteen days. There are at least two broods in the year. 

 The larva is two-fifths of an inch long, and has six feet and two 

 anal spines, and the sides of the segments pointed : it is 

 brownish-black except the sides, which are yellowish-grey. 



Prevention and Remedies. — Paying attention to farmyard 

 manure used : as the beetles breed in this, it should be ploughed 

 in at once on wurzel land where the pest occurs. 



The Easpbbeey BebtIjES (Bytueus tombntosus (RosiE)). 



Of all Easpberry pests the so-called Easpberry Bug, the 

 Byturus tomentosus, is the most noxious. The beetle is about 

 one-sixth of an inch long, dark-brown in colour, with a dense 

 golden-brown pubescence. It belongs to the Nitidulidm, the 

 same family that contains the Mustard Blossom "Weevil. We 

 notice these beetles at their work in May upon the canes, 

 eating the flower-buds at their base. The females deposit their 

 eggs singly in the fruit-buds, and from these come the larvae at 

 about the time the fruit is formed, which at once commence 

 feeding upon it and thus spoil it entirely or reduce it in size. 

 This grub, which we often eat in the fruit, is yellowish, with 

 brown marks in the middle of each segment and about one- 

 third of an inch in length ; at the tail end are two curved 

 projecting points. When mature it falls to the ground or gets 

 into the holes in the canes and poles, and there pupates and 

 remains all the winter* 



Prevention and Remedies.— AMinvini application of gas-lime 

 round the canes and the destruction of prunings is about all 

 we can do to prevent a recurrence of this attack. Where we 

 see numbers in the plantations, in May, we might clear them ofi' 

 by jarring over tarred boards or by arsenical spraying. 



Ground-beetles or CaeabidjE. 



The Ground-beetles or Carabidse form a very extensive family. 

 These beetles belong to a division called Geodephaga, and may
