per day. Still the Coffee recovered Lime, salt, 



carbolic acid, and other remedies were tried, but without 

 effect, I believe."* 



As various kinds of Cockchafers feed at the roots of 

 grasses, this fact might sometimes give a clue to where 

 attack comes from, and when grass-land is being broken 

 up, or arable- or garden-land, known to be infested, is 

 temporarily empty of crop, hand-picking or turning on 

 pigs, whilst the plough or spade are at work, would 

 do good. 



For prevention of injury from the above-mentioned and 

 the preceding beetle-attack, specimens of the grubs are 

 needed for figuring ; likewise information as to ivhat kinds 

 of crops they chiefly feed at the roots of; hoiv long they 

 live ; how deep they lie in the ground ; hoiv deep they 

 go down to turn to the chrysalis condition; and also 

 whether they are found at the roots of wild grasses or in 

 decayed vegetable matter in woods. Also, what time of 

 day or evening the beetles are in the quietest state, and 

 what measures, if any, have been taken for reducing the 

 numbers of the pest.
