28 CORN AND GRASS. 
Every leaf in my garden on Peas, Roses, Strawberries, Raspberries, is 
being eaten, leaving nothing but lacework, by what I think is the Rose 
Bug. I never saw such a quantity. The hearts of the Roses are 
swarming with them.’’ Samples accompanying were submitted to 
Mr. G. H. Carpenter, Consulting Entomologist to the Royal Dublin 
Society, who identified them as the Phyllopertha horticola, giving the 
requisite advice.—(Kd.) 
On June 18th, I was favoured with a note from Dr. C. Theodore 
Williams, of 2, Upper Brook Street, London, W., regarding beetles 
which were infesting Roses in his garden at Witley in Surrey. 
These also proved to be the Phyllopertha horticola, or Rose Chafer, 
and were doing much mischief by eating ‘‘the petals of all the 
Roses.” 
On the 20th of June I had the following useful note sent me by 
Mr. T. P. Newman, of Hazelhurst, Haslemere, Surrey, in which dis- 
trict * the Rose Chafers, which were so mischievous in beetle state to 
Roses and various kinds of leafage, and most seriously destructive in 
maggot state to roots of grass in pasture-land in 1898, are still 
troublesome. 
Mr. Newman remarked :—‘ There would seem to be no royal road 
to destroying this pest; but it is comparatively easy to destroy many 
thousands, and this must surely have some effect in both present and 
future depredations. The beetles are especially fond of the fully- 
opened and fading blossoms of Rosa rugosa, as well as of the Scotch, 
Austrian, and Persian Roses. It is quite worth considering whether 
it is not worth while to plant a few bushes of Rosa rugosa to attract 
the beetles away from fruit-trees. They cluster in groups of a dozen 
or more on a flower-head. 
‘‘ By holding a small fish-can under and tapping the blossoms, the 
beetles, which are very suspicious, drop into the can; as they are 
sluggish in the evening, this is the best time. In case they are lively 
the lid of the can is shut down on them. Scalding water kills them, 
and to make sure of destroying the eggs, they are finally burned on 
the rubbish-heap. In this way I destroyed about a thousand a night 
in about half an hour for three or four nights. The main attack does 
not last much longer. Isolated specimens and pairs are, however, 
still abroad.”’ 
This observation of Mr. Newman’s as to short duration of the main 
attack is well worth notice, for in an attack of this kind it is very apt 
to happen that while people are thinking what to do, or whom to ask 
about it, the mischief for the present attack, and egg-laying for the 
next, is completed, and the insects gone.
