XV. — RHYNCHOTA MALAYANA. PART I. By W. Iv. Distant. It is proposed in these papers, to give from time to time, contributions to a knowledge of the Rh^mchota found to the east of the limits of the area dealt with in the volumes descriptive of the Fauna of British India. A number of species are common to the two areas, and to understand the components of the one, it is necessary to have a knowledge of the other. In fact North iVustralia cannot be eliminated though it is not proposed to deal with it in these papers. One of the rarest and most distinc-tive species in the Indian Pentatomidse is Aniblycara gladiatoria, Stal. It had only been recorded from " India " and Ceylon, and was of the utmost rarity in collections. Quite recently the British Museum received a specimen collected by Mr. Dodd in Queensland. It is also proposed to occasionalh' illustrate some of the many Malayan species described by Walker, the descriptions of which are frequentlj^ inadequate and provocative of synonym}' by writers who cannot consult the types.
