( 591 ) XXVI. A71 Enumeration of the Rhynchota collected during^ the Expedition of the British Ornithologist&' Union to Central Dutch New Guinea. By W. L Distant. [Read October 4tli, 1911.] Plate XLIX. The collection of Rhynchota brought home by this expedition consists of fifty species, of which ten are described as new, while it has been found necessary to propose three new genera. In 1888, and iu the Transactions of this Society, I had the pleasure to give the results of an examination of the Ehynchota collected by Mr. Sayer during Mr. Cuthbertson's expedition to New Guinea. The number of species than obtained was forty-eight, so that the results of the present expedition, in the face of many hindrances, is in a Rhynchotal sense not unsatisfactory. It is at the same time far indeed from being exhaustive, and only affords a sample of the mateiial which we may expect as the result of another expedition under more fortunate circumstances. The species here enumerated were all collected by Mr. A. P. R. WoUaston, and on the banks of the Mimika and Wataikwa Rivers. Suborder HETEROPTERA. Family PENTATOMIDAE. Tectocoris lineola.
