COTTONY PINE APHIS.

possible to give, for practical purposes, observations of one species 
distinct from the other (any more than of the different common kinds 
of Turnip Flea-beetle), as several kinds appear to feed almost in¬ 
discriminately on Peas, Beans, or Clover; sometimes as Weevils on 
the leafage (as we have long known) ; and sometimes (as we have 
learnt in the last two years) in their first stage as maggots at the root. 
One great point of prevention would be to keep the autumn Weevils 
from taking up their quarters in stubble, either for winter shelter 
down the straws, or for egg-laying by going down in the earth amongst 
the Clover roots. 
Belatively to the first habit, the Rev. J. C. Clutterbuck, who 
devoted especial attention to this point, mentioned, as noted before :— 
“ We traced the sometimes total loss of Trifolium to this source, as we 
found the insects in the top joint of the stubble, amongst which we 
generally drilled the Trifolium incarnatum without ploughing. We 
lightly skimmed the stubble, and so deprived the Weevil of its habitat 
and refuge; and we believe we abated the evil.” 
With regard to treatment that might act in making the ground 
obnoxious to the Weevil and favourable to the support of the attacked 
Clover, Peas, or Beans, as by dressings of lime, gas-lime, or other 
applications or treatment generally, any practical information would 
be thankfully received. 
PINE. 
Cottony Pine Aphis. Schizoneura fuliginom, Buckton. 
Mr. Angus McIntosh, writing from Llanercli, Llanelly, S. Wales, 
gives a note of the effect of Paris green (arsenite of copper) in getting 
rid of Schizoneura fuliginosa on infested Pines. 
[This Aphis is found on P. Austriaca and also on P. sylvestris. It 
may be generally described as black, hairy, and somewhat coated with 
a mealy secretion when fully developed; with a greyish wool rather 
than hair in the preceding stage, when it has only wing-cases. It 
forms white cottony tufts in the axils of the leaves. See ‘ British 
Aphides,’ by G. B. Buckton, F.R.S., vol. iii., p. 96.— Ed.] 
Mr. McIntosh says :—“ I put two tablespoonfuls of the green into 
a bucket of water and sprinkled it rather heavily over the Pines with 
a watering-can. The application soon killed the insect, but it nearly 
killed some of the Pines ! The dose was too strong. A little less 
than a tablespoonful of ‘ green ’ to a bucket of water would, I fancy,
