( 475 ) XIII. All enumeration of the Rhyncliota received from Baron ron Midler, and collected by Mr. Sayer in Neic Guinea durinq Mr. Cuthhert son's Expedition. By W. L. Distant, F.E.S. [Read October 3rd, 1888.] Plate XIII. The Rhynchota collected by Mr. Sayer, though lev/ in number, are of great interest, and add considerably to our knowledge of that portion of the entomological fauna of New Guinea in which they were collected. The largest number of species from the island, of which we have record, were described by Mr. Walker, collected by Mr. Wallace, and are now contained in the British Museum. The late Dr. Stal has also con-tributed some scattered descriptions, and Dr. Signoret more recently gave a short descriptive paper of New Guinea Heteroptera belonging to the collection in the Genoa Museum. Consequently, even with the additions made by this paper, our knowledge is still very limited as to the Rhynchotal element in this entomological fauna. In the Heteroptera of ttiis collection are 39 species ; of these I have identified 37 species, 13 being hitherto undescribed and embracing 5 new genera. The Homoptera comprise 9 species ; of these 8 are identi-fied, 4 being hitherto undescribed, including one new genus. Other species in both groupie were represented by larval forms only, and it would be presumption to attempt their identification. In this collection the Australian element or affinity is exceedingly slight, a considerable relationship exists with the fauna of the adjacent islands, and a few species are probably peculiar to New Guinea ; but our present know-ledge is so very limited, and the available collections so very small, that it is futile to hazard any dogmas as to geographical distribution.
