ENTOMOLOGY. 133 



in the morning. The antennae have a constant 

 tremulous motion up and down,wliich is the case 

 with the whole family of tenthredinidae. On 

 turning up the leaves of the gooseberrry bushes 

 at these periods, we shall find that many of 

 them have the ribs studded over with transparent 

 ova, which swell out gradually until the little ani- 

 mal makes it escape; whilst larvae, of various 

 sizes, are consuming other parts of the vfoliage. 



In this stage, finely powdered lime, soot, or 

 dry dust of almost any kind, scattered upon the. 

 leaves, and especially immediately after rain, will 

 stop the grub from eating, and render it feeble. 

 If the bushes be then well shaken, the insects 

 may be gathered in large quantities from the 

 ground underneath ; and, perhaps, this is the 

 speediest way of reducing their numbers when 

 they have been previously neglected; but the 

 fruit and the tree will be rendered very unsightly 

 by this process. Such persons as attach proper 

 importance to neatness in their garden have no 

 remedy so effective as the tedious one of picking 

 the larvae carefully from the leaves, when they 

 make their first appearance, to prevent their retir- 

 ing into the ground, to undergo their changes, 

 and produce a far more numerous progeny. 



When we consider the thousands of these
