.DOXXXVI--COCCID PESTS ON SUGAR CANE. 
In the Kew Report ae 1877, p. 39, reference is made to Coccids 
or scale insects, that had ravag ged the cane fields of Bourbon 
and Mauritius, known locally as “le pou a poche blanc he.” 
Mr. Robert McLachlan, F.R.S., pointed out that this was a 
collective name, and probably cadet several species. The most 
prominent at the time was believed to be Icer ya sacchari, Guérin- 
Méneville. 
omewhat similar insects pss made their appearance on sugar 
cane in Queensland. One of these was afterwards identified as 
Icerya Purchasi, Maskell, fully described (with a coloured plate) 
in Kew Bulletin A puse pp. 191-216). 
In 1887, correspondence relating to the attacks of Coccids 
i forest on in the island of Rodrigues Pie referred to Kew 
specimens by the Secretary of State for the Colonies. 
Mr. McLachlan had little doubt that these ned were identical 
with those that * had long been known to ei Koss damage 
in the neighbouring islands of Bourbon and Mau 
. The following further information has been diede respecting 
the Mauritius insects :—

done much injury to Sugar-cane in that island. He called it “le
