10 CABBAGE. 
whilst preparing this paper, I was favoured by Mr. Robert Newstead, 
of the Grosvenor Museum, Chester, with a sight of his beautiful 
figures, drawn from life, of this Scale insect, Cryptococcus fagi, prepared 
by him for one of the illustrations of his ‘Monograph on Coccide’ for 
the Ray Society. These figures give full and excellent representation 
of the upper and under side of the female Coccus, with all details; and 
likewise of the larva, showing the narrower form, the six legs in 
position, and many additional much-magnified figures, which will be 
of the greatest service to future students of this infestation. 
In regard to methods of prevention and remedy, probably syringings 
or washings of water would be useless, as in some experiments which 
Mr. G. B. Buckton, F.R.S., was good enough to try for me on speci- 
mens of infested bark, he found that the felt-like or ‘‘ furry’ matter 
was quite insoluble in water. Probably soft-soap washes, with a little 
sulphur, or a little mineral oil of some kind, incorporated in them, 
would clear the infestation well, for they would be prevented by the 
‘“‘felt’’ from running off at once, and thus remain to destroy the 
contained insects or eggs. 
But here, as with other forest insect attacks, it would be impossible 
at a paying rate to apply dressings to large areas of infested woodland. 
Small numbers of trees, or trees which for any particular reason it was 
wished should be preserved, might in all probability be cleared from 
the attack, but further than that, remedial measures do not seem 
available. 
CABBAGE. 
Cabbage Aphis. Aphis brassice, Linn.; Aphis floris rape, Curtis. 
Apuis FLORIS RAP#, Curtis.—1, 2, male Aphis ;" 3, 4, wingless female—natural 
size and magnified. 
On July 28rd specimens of very bad attack of Cabbage Aphis were 
sent me by Mr. Samuel Fraser, from the Cheshire Agricultural and
