 good results have been secured without the sticker. Such spraying 

 should be given as soon as cutting is over and should be repeated

 are kept closely cut and the bed is then sprayed, there should be no 

 trouble to control the pest, and young beds should be kept thor- 

 oughly sprayed with arsenate of lead from the time the beetles 

 appear until danger from injury is over. 



The Twelve-spotted Asparagus-beetle * 



The Twelve-spotted Asparagus Beetle is also of European 

 origin, having been first introduced into this country near 

 Baltimore, Md., in 1881. Since then it has become almost as 

 widely distributed as the previous species. 



The beetles may be distinguished from the last species by the 

 broader wing-covers, each of which is orange-red, marked with six

 which emerge from hibernation feeding on the young shoots. 

 Later generations attack the foliage, but the larvae seem to prefer 

 to feed upon the ripening berries. The larva is of the same gen-
