"Icerya purchasi, that was the name, something like that. It's a coccid, a little scale insect. It had those same shapes collected together within its individual cells." "What do they mean? What is the connection with Dis?" "I don't know," she said; "it's just that they look so similar. And I never saw anything like this in a human cell before.
Is it any wonder that orchard after orchard was entirely freed from the pest, until now over a large section of the State hardly an Icerya is to be found? And could a more striking illustration of the value of the study of insects possibly be instanced?
In less than a year from the time when the first of these hungry Australians was liberated from his box in Los Angeles the orange trees were once more in bloom and were resuming their old-time verdure the Icerya had become practically a thing of the past. This wonderful success encouraged other efforts in the same direction.
Cockerell in Jamaica has noted an interesting Coccid, Icerya rosæ, which is protected by ants; "at the present moment some of these Iceryæ are enjoying life, which would certainly have perished at my hands but for the inconvenience presented by the numbers of stinging ants." Nature, 27th April 1893. Mr.
