scales. These eggs remain unchanged during the remainder of the 
year, and it is not until the following spring that the young mites 
escape from them. With regard to methods of prevention by killing 
the eggs, no information has been brought forward. 
‘Of the hitherto described species of Bryobia, the Gooseberry Mite, 
the B. nobilis of C. L. Koch, comes the nearest; however, according 
to Koch’s drawing and description, characteristic differences are present 
which clearly permit venturing identification of two species. 
‘«‘ As hitherto no notice has been given of this increasing, and in 
dry years very dangerous, enemy of Gooseberry-growing, in German 
serials, or books of instruction, or in statements in known literature, 
the report in Wittmack’s ‘ Gartenflora’ of the year 1894, containing a 
fully detailed communication on the subject with figure accompanying, 
was published.”—(F. I.)* To this Dr. Thomas adds a few lines 
relatively to my having contemporaneously brought forward in my 
own Annual Report considerations regarding the injurious infestation 
of Gooseberry Red Spider in England. 
As the matter stands at present, it appears to me that we have two, 
and possibly more kinds of what, for all practical purposes, it is enough 
for us to know as Red Spider on Gooseberry-bushes, and that these 
kinds are so similar in their habits, that they lhe under the same means 
of preventive treatment. 
Of the applications most serviceable for this purpose, all observations 
(that 1 am acquainted with) agree in stating that washings with a basis 
of soft-soap are most useful. The ‘‘ Kerosine Emulsion,’ so much 
thought of in the U.S.A. (especially if used warm), is an excellent 
application, and what may be called its ‘‘ British representative,” the 
««Anti-pest,”” manufactured by Messrs. Morris, Little & Son, of Don- 
caster, is very widely used, and with great success, and is to be recom- 
mended for use by all those who have not acquired the difficult knack 
to master, of so blending the soap and mineral oil of the Kerosine 
Emulsion that they shall not again separate. I also believe that a 
composition with a basis of soft-soap, brought out by Messrs. Stott 
under the trade-name of ‘‘ Kill’mright,’’ has been found serviceable. 
Dry dressings, such as soot, or slacked lime, have been reported to 
me as useless, as also application of paraffin oil much diluted, but 
without soap added. 
Where very plentiful washings with water alone can be given, these 
are serviceable, because, as pointed out in Dr. Friedrich Thomas’s paper 
before referred to, this partly stupefies the mites,—causes a lethargic 
condition from which, if soon dried, they recover, but in which, if con- 
tinued for some days, they waste. 
* See paper by Dr. Thomas, from whose short leaflet on the same subject I 
have translated the above, of which the title is previously given.
