Fauna Sumatrensis. (Bijdrage Nr. 65). COCCI DAE. By E. Ernest Green, f. e. s. f. z. s. (With IO figures). The material which forms the subject of the following notes was collected by Mr. EDWARD JACOBSON in Sumatra during the years 1923 to 1927 and submitted to me for identification. The publication of the results has been delayed, firstly, by preasure of other work, and, later, by a serious illness. The types will remain in the collection of the author and cotypes (where there are such) will be deposited at the British Museum of Natural History. Though the collection contains but a few species (23 in all) it is interesting from the fact that barely half-a-dozen species of Coccidae had been recorded from this island. From its proximity to the neighboring island of Java, it might be expected that Sumatra would possess a Coccid fauna very similar to that of its nearest neighbour. But an analysis of the species represented in this collection shows that nine of them are new and are described below for the first time, six are of almost cosmopolitan distribution, another six have their head quarters in the Indian Region, one species [Lepidosaphes banibusicold) was originally described from Brazil, while only a single peculiar Javan species [Odoiiaspis sacha-ricaulis) occured in the Sumatran collection, which contained the following twenty three species : 1. Drosicha sumatrensis sp. nov. Adult cTcT. Presumably caught on the wing. 2. Icerya nuda sp. nov. On Gigantochloa aspera. A single $, containing well developed embryos.
