I also met the man who had been employed at the time in 1880 when Mr. Hart- mann received an illustration from Brisbane of Icerya,and directed him to look over the trees for specimens, when several scales were found. Since then, however, none have been found. While looking over the "lemon and orange trees I found one single nearly full-grown specimen, but aside from this no trace of them. A peculiar Coccid resembling Icerya somewhat in structure was found on au apple-tree. The gentle- man informed me that Icerya was always most noticeable in wet seasons, but that it never appeared in such numbers as to be injurious. I found here in abundance the large hemipterous insect so destruct- ive to the orange in Queensland and New South Wales. A second species somewhat smaller than this, yet equally mischievous, was found at Adelaide (Fig. 10). Trees were observed at this place with all the fruit and most of the young- shoots destroyed. Both spe- cies live and grow upon the sap of fruit and tender twigs.* Aspidiotus aurantii ^ was present here iu numbers and also Leeanium olea\ both upon oranges; the latter, however, is kept well iu. ,„ „.,. check by a lepidopterous /aua-uatural size (iVocf JUfZ) larva, ThaUKH'hareS ^,i„^^i^, ^^^^^.^^^ ,„,i„i4l) (migiuai). cocciphaga^ Meyrick (Fig. 11). Several young orange trees had been completely cleaned by larvie, and eight chrysalids were found upon a young plant. Mr. H. Ilartmanu also informed me that near Brisbane a dipterous larva existed which occasionally destroyed all the orange crops, and in 1880, which was a very wet season, a dipterous larva destroyed not only all the oranges but also nearly all the other fruits, even the apples and pears. Pie also gave me the following list as blight-proof apple-trees: "Northern Spy, Majetin, Irish Peach, Streaked Peach, Hart
