the branches at ground level, so as to get out all harbour for 

 the mites ; but the matter is very difficult to meet, and as in 

 the experiments on the Phijtoptus of the Orange in Florida, 

 the best results given were those of treatment with whale-oil 

 soap, it may be hoped that tliorougli application of Mr. Arthur 

 Ball's recipe above given, of soft-soap with sulphur, might be 

 of service. 



White Woolly Currant Scale. Pulcinaria ribesice, Signoret. 



PuJrinaria rihesicv : 1, female and woolly egg-?ac, mag. (nat. size given at 

 p. 308); 1((, female Scale, mag., with line giving nat. length; 2, larva, mag. 



The accompanying sketch (see p. 308) is taken from a 

 photograph of a Currant-bough infested by the White Woolly 

 Currant Scale, the Pulvinai-ia rihcsice, Signoret, a kind of 

 attack which is known in France, but which, although we 

 now find that it has been present at various places in England 

 and Scotland during the last few years, has not been scienti- 

 fically identified and recorded as present in Britain until 

 June, 1889. 



On June 18th, specimens of the attack were sent me from 

 the garden of Mr. George Parkin (by whom they were first

 Park, Huddersfield, with a note that it evidently " seemed at 

 home where it was established, and that the Pied Cm-rant 

 bushes were terribly affected by it " ; and he drew my atten- 

 tion to the very great number of eggs in the cottony matter 

 surrounding the Scale. 



The specimens were submitted by Mr. S. L. Mosley to Mr. 

 J. W. Douglas, of 8, Beaufort Gardens, Lewisham, S.E,, for 

 authoritative identification, who reported on them as fol- 

 lows: — "The Coccids you sent are Pulrlnaria rihes'ue, Sig- 

 noret ('Essai sur les Cochenillcs,' p. 219), a species found on 

 Pied Currant bushes in France, and which I have long ex- 

 pected to hear inhabited Britain, but until now I have not 

 seen it." As this kind has not yet been brought forward
