ill Whiteheavts and BiKaroons. They do not occur in tlie " Guigne a

Should tliis insect, which may be British, but which in any case is 

 very rare, "ic' irh.'ch is iuqHirtrd in fnreiijn fruit, become noticeable in any 

 lilantation or uarden, it would be wise to forego any crop by having all 

 the fruit destroyed to prevent damage another year and the possible 

 spread to other plantations near, and so, perhaps, <:iver the whole southern 

 part I if the country. 



THE JAPANESE OR WEST INDIAN FRUIT SCALE. 



(Diasjiis peiittifioiin. Targ.-Tozz. = Diaspis aini/giiaJi. Tryon.) 



Although, as far as we know, this insect is not found in Britain to-dav, 

 we nnist not overlook the fact that it has been imported and has lived here. 



Xewstead (1) quotes its ap- 

 pearance at Kew in March 1898 

 on Pniniis jjsenrlo-cerasHs, on plants 

 imported from Japan which had 

 been out of doors since Januarv 

 in the same year. Agaiu (2), in

 of Tryon. On inquiry it w-as found that the greater number of the 

 plants of this particular batch (100) had been planted nut of doors 

 .since the time (if arrival, and the examination proved the insects were 

 not in any way att'ected by their change of climate, but .appeared in 

 a perfectly healthy condition. " Later, June 3rd, the insects were still

 have been traced. Enough w-as seen, howevei', to show- that the insect 

 can live in the open in England.
