MAGPIE MOTH ; GOOSEBERRY AND CURRANT SAWFLY. 313 



When caterpillars are first found to be attacking the bushes 

 (as they do not throw themselves down readily on disturbance), 

 many may be got rid of by a man with scissors in one hand 

 and a jug or pail (with some mixture in it that the grubs can- 

 not escape out of) in the other, snipping off the infested leaves 

 into the vessel. 



All the measures of hand-pickiug, shaking down, and 

 destroying the caterpillars under the bushes, dusting with 

 various applications, dressing under the bushes in winter or 

 early spring with lime or gas-lime, &c., which are found 

 serviceable in checking the attack of Gooseberry Sawfly 

 caterpillar, and of which an abstract is given in the following 

 paper, would be equally serviceable in lessening damage from 

 Magpie caterpillars, which are easily kept in check by 

 moderate care.

The attack of Sawfly caterpillars on Gooseberry leafage is 

 one which appears certain to show itself more or less every 

 year ; and often, and especially in bush-fruit growing districts, 

 causes great loss to the growers. The chief characteristics of 

 the attack are only too easily observable ; but for further 

 information as to habits, all necessary details will be found in 

 the paper on this Gooseberry Sawfly, pubhshed by John Curtis 

 in the vol. of the ' Gardeners' Chronicle ' for 1841, from which 

 most of the following notes of the Ufe-history of this insect 

 are taken.
