so as to show clearly what insect is meant. Figure 11. 1 shows the 



papa, 2 the grub, 3 and 

 4 side and dorsal views 

 of the beetle. This 

 insect is known as the 

 "May Beetle," "June 

 Bug" and "White 

 Grub." In the larvae 

 state it feeds upon the 

 roots of plants having 

 done much damage to 

 grass lands and espec- 

 ially to strawberry 

 vines The beetle feeds 

 upon the foliage of trees 

 and where abundant 

 often entirely stripping them of their leaves. The beetle is attracted 

 by lights and is a frequent evening visitor to our living rooms while 

 on the wing. The impression prevails that the eggs are laid on 

 grass near the roots though perhaps this matter may bear further 

 study. 



REMEDIES. 



The Department of Agriculture at Washington, D. C, has con- 

 ducted some experiments to show that kerosene emulsion liberally 

 applied to the soil infested with "white grubs" will destroy them. 

 The remedy would be too troublesome and expensive for applica- 

 tion in large meadows but for small areas is worthy of trial. We 

 extract the following from Prof Riley's letter regarding the subject : 

 "The application of kerosene emulsion for white grubs is imprac- 

 ticable over very large areas owing to the necessity of washing the 

 emulsion into the soil to considerable depth by a copious applica- 

 tion of water, unless the application can be made with tolerable 

 certainty of its being followed by slow and continuous rains such 

 as will carry it into the soil gradually without washing it away. 

 These conditions will not often be available at the time wanted, 

 but for all limited applications as to lawns or limited patches of 

 ground affected by the larva 1 , there is no better remedy than the 

 kerosene emulsion treatment. I have no accurate data as to the 

 amount required per acre but if the emulsion is applied sufficiently 

 to thoroughly wet the surface of the soil to the depth of an inch or
