Mr. C. V. Riley identified this scale as Chion- aspis citri, which is still common and destructive here, but probably less so now than the Purple Scale and Icerya. However, it is a matter of history that long before the date given by Mr. Heyl the orange trees had suffez'ed severely from disease, probably due to Scale-insects, and that their cultivation had consequently greatly diminished before 1836.* (See p. 635.) Probably the Purple Scale was introduced at an earlier date than the others and had been equally destructive. The Icerya is a much later introduction, prob- ably subsequent to 1876. * Bishop Berkeley, 1724, and W. F. Williams, 1848, mentioned the scarcity of oranges at these dates. According to the former they had then been scarce for 40 years, or since 1684, due, as he supposed, to cutting down the cedar forests ; but Scale-insects vsiay have been the main cause.
