2() THE COMMON HAIRY ROSE BEETLE.

 lays eggs in heaps of old manure, from which hatch larv^ re- 

 sembling very closely the injurious white-grubs, but ^vhich 

 are not injurious to the roots of living plants. 



Among the many remedies proposed against the noxious 

 may-beetles are several that should be mentioned, because 

 they are of some benefit. It is well known that the winged 

 beetles are readily attracted to light, and rooms that are 

 not protected Ida' screens will soon contain large numbers of 

 such clumsy beetles attracted to them by burning lamps. 

 To attract these beetles for the sake of killing them it is cus- 

 tomary to place a burning lamp over a pan filled with wat- 

 er and kerosene-oil. The insects, attracted by the light, fly 

 against the protecting glass and, falling in the water, come 

 in contact with the deadly oil. In this manner large num- 

 bers of beetles can be caught, but on investigating the in- 

 sects captured we find that most of them are individ- 

 uals that have already deposited their eggs, or we find that 

 only one sex, usually the male, has been captured. At all 

 events, notwithstanding the number of insects killed, the 

 benefit is not so great as could be expected* By beating the 

 trees at night, and gathering the falling insects into sheets 

 and bags, large numbers of the recently emerged beetles can 

 be caught, but such an operation requires very much labor 

 and is consequently not a practical remedy. 



All birds, and most of our carnivorous mammals, should 

 be protected, and not killed on sight, as is frequently the 

 case at the present time. In fig. 15, plate II, the smaller 

 beetle is L. trl.^fls^ the larger L. rugosa. 



THE COMMON HAIRY ROSE-BEETLE. 



{Euphorhi imhi Linn.). 



This insect has of late years become very numerous and 

 injurious in our state. It is a hair3' beetle, gray in color, 

 spotted with black, as may be seen in the illustration (fig, 

 17, plate VI), which shows a number of them. Its larva 

 possesses also the general shape and appearance of the com- 

 mon white-grub. The adult insect occurs in large numbers 

 during autumn, and again in spring and early summer. The
