but these are not sufficient, and other means must be employed to 

 get rid of them. Various animals, — shrews, moles and others that 

 burrow, destroy many. Certain birds, — robins, crows, blue-jays, 

 black-birds, etc. also eat them, and the tiger beetles kill them. There 

 is also a white fungus which sometimes grows in two long processes 

 from the grubs, one on each side of the head, which destroys them. 



Various artificial remedies have been suggested, as the mixing of 

 wood ashes with the soil, which makes it very unpleasant for the 

 grubs, and in some cases has proved very efficient. Shaking the 

 beetles from the trees on to sheets and then burning them is recom- 

 mended. This can be done best early in the morning. Late fall 

 plowing has also been recommended, but to reach the grubs it must 

 be deep, for they burrow down a considerable depth in order to pass 

 the winter. Swine and domestic fowls are fond of the grubs, and 

 will destroy them when allowed to have access to the infested field. 



From experiments made by Mr. W. B. Alwood, it is probable that 

 kerosene emulsion may be used successfully for the destruction of 

 this insect wliile in the ground, but it is necessary to thoroughly 

 drench the ground, for the purpose of reaching the grubs. This plan 

 is well worth a trial on lawns, but it is doubtful if it would pay in 

 fields. 



THE PLUM CURCULIO. 



Conotrachelus nenuphar (Herbst.) 



The plum curculio belongs to the group of snout-beetles or weevils, 

 and is very injurious to cherry, quince, peach, and apple trees, as 

 well as plum trees. The perfect beetle, fig. 8, c, is about one-fifth 

 of an inch long, grayish-brown or black in color, while on the wing
