ROSE OHAFER. BY 
the garden, and I fancy that in the sunshine it must have made a 
dampness in the air around it such as all insects seem to love.”’ 
In reply to my enquiry whether the soap used was of any particular 
sort, Mrs. Beveridge kindly wrote as follows :— 
«The soap which was in the water (with which I syringed a Rose 
bush, under which, later in the day, I found many dead Rose Beetles) 
was unscented Pears’ soap. I will, if it is in my power, try next year 
some experiments with this and with soft-soap.”—(A. L. B.) 
Mrs. Beveridge’s careful notes give two or three useful points for 
consideration: one, the fact of the chafers coming in both years to 
infest the garden from the same neighbouring breeding grounds ; 
another, the fondness of pigs for the beetles, which, like many other 
similar facts, though we may have them on record, it is always 
desirable to have fresh, live examples of; and thirdly, the very great 
numbers in which the Rose Beetles were attracted to the bush syringed 
with soapy water, followed by many dead beetles being found beneath 
this bush and none found dead elsewhere. In whatever manner the 
soapy water may have acted, it is at least serviceable to know of a way 
in which the beetles may be attracted together in hot weather; and 
though, as Mrs. Beveridge added in her letter to myself, she would 
experiment again, ‘‘as she would not like to base an opinion on only 
one year’s observation,’’ this may have given us a clue to attracting 
the beetles by soap and water, which would act still more surely for a 
little of some insecticide, Paris-green, for instance, being added. ; 
During the summer I had not many observations of chafers, but 
with September they again occurred. On Sept. 8th a packet of grubs 
of the Rose Chafer, Phyllopertha horticola, was sent me by Mr. J. 
T. Brown (sub-editor of ‘The Cable’), on the part of the Karl of 
Winchilsea, with the request that I would identify the pest, and name 
means for preventing its ravages, as a field of grass laid down two 
years previously had suffered considerable damage from its inroads. 
On Sept. 14th Mr. G. S. Ware wrote me from Hriswell, Brandon, 
regarding grubs sent accompanying, of which he remarked :— 
«‘They are doing a lot of damage to the newly set Rye and 
Mustard. They are to be found amongst all old layers.”’ 
The samples sent proved to be Rose Chafer grubs, not yet full 
grown; and with the power, possessed by this kind of .grub, of 
straightening itself out from the curved shape, lying on one side, in 
which it so much resembles a young Cockchafer grub, and resting on 
the lower surface in the common larval manner, walking along with 
the help of its three pairs of claw-legs, at a fairly quick pace. 
On Sept. 17th Mr. Ware remarked :— 
‘‘T suppose the Rose Chafer is much the same insect as the 
‘Choovie’? We find that rolling with our heaviest roller has the
