26 THE COMMON HAIRY ROSE BEETLE. 
black and shiny beetle ( Chalepus trachypygus Burm.), which 
lays eggs in heaps of old manure, from which hatch larve re- 
sembling very closely the injurious white-grubs, but which 
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 by 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 ourcarnivorous 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. tristis, the larger L. rugosa. 
THE COMMON HAIRY ROSE-BEETLE. 
(Luphoria inda Lann.). 
This insect has of late years become very numerous and 
“injurious in our state. Itis a hairy 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 andearlysummer. The
