the application of soot and lime to-the roots, and watering with ammoniacal liquor 
and common agricultural salt. 
O. picipes chiefly attacks raspberries and sometimes does a great 
deal of damage; beating the trees after dark with trays smeared with 
tar has been found of great service in checking their ravages. 
O. tenebricosus does not apparently do much damage in Britain, 
but has been recorded as attacking the buds, shoots, young leaves, &c., of 
apricots, nectarines, peaches, plums, &., and the roots of raspberries, 
currants, gooseberries and strawberries ; the latter plant is also some- 
times injured by O. sulcatus. Seventeen species have been usually 
regarded as British, but O. ambiguus is scarcely distinct from O. rugi- 
frons, and O. ebeninus is somewhat doubtful.
