49 GOOSEBERRY. 
15th of March, gave the same account of great appearance followed by 
disappearance. He observed :—‘‘ At that time I was receiving grievous 
letters of complaint. One I had from Mr. Granger, of Ely (a large 
grower and jam manufacturer), in which he says, ‘ My Gooseberry-buds 
are quite red with the Spider’; and others of a similar nature. 
Since then we have had showery weather, and I am pleased to say that 
quite three-fourths of Spiders have disappeared. Whether it may be 
that they have only gone down into the soil to reappear at a more 
favourable season, Iam unable to say; but the fact remains that at 
the present moment there are many bushes on which I can find none, 
and where I can find them they are in the centre of the bush nearest to 
the ground. ‘There are positively none on the outside branches.”’ 
A few other observations were sent me, but nothing like the report 
of damage sent in the two previous years; and nothing was added to 
methods of prevention and remedy, excepting still further proof of the 
absolute necessity of applying such of these as we know act reliably on 
the very first appearance of Red Spider in late winter or early spring. 
On the 29th of April Mr. Nixon (before mentioned, who has 
observed and reported this attack to me regularly from its first bad 
outburst in 1893) mentioned, in sending me some specimens I had 
asked for, that these were not from his own grounds, as he was glad to 
say he had positively none; he had finished syringing for the second 
time about three weeks before, and since then he had scarcely been 
able to find a single live Spider, and to find one at all required looking 
over many bushes. ‘‘ My bushes are practically cleared; it is the best 
result I have ever attained, and I attribute it solely to the fact of my 
commencing to syringe as early as possible when the Spiders were only just 
hatched, and no foliage to shelter them.’’—(F. N.) 
Quite absolute certainty as to what distinct species of the 
Gooseberry Red Spider (scientifically, Bryobia) may be present, is a 
point which none but skilled experts can decide; and resting on this 
we appear to have two species present, one of these being, as men- 
tioned in my two preceding Reports, the B. pretiosa, of C. L. Koch, as 
kindly identified for me by the skilled determination of Mr. Albert 
Michael, F'.L.8.* The other proves, from the investigation of Dr. F. 
Thomas, of Ohrdruf, during 1894 and 1895, to be a species hitherto 
undescribed, which he has named B. ribis. For those who wish to go 
into the subject fully in minute detail, with the points of distinction 
between the above and various other species, the information will be 
found in the paper mentioned below. t
