(1956) Marshall, The Otiorrhynchine Curculionidae of the tribe Celeuthetini (Col.), 1956, p. 28, British Museum, London Fig. 2 Marshall based the genus Zeugorrhinus on a species collected at Kieta, Bougainville Islands, in 1937 (J. L. Fraggott). As far as the writer is aware, granuJattis is the only species now as- signed to the genus. No specimens of this species have been available for study. Marshall indicates that this taxon is most nearly allied to Elytrochei- his Fst., consisting of some 20 species which are mainly found on New Guinea, Louisiade Archi- pelago and Woodlark Islands. An examination of several specimens of Elytrocheihts confinis Fst. from Oro Bay, New Guinea collected by Harry P. Chandler, 1944, confinns Marshall's state- ment as to the characteristics of the genus Elytro- clieiliis; "the basal sulcus of the rostrum is com- plete; the head is not constricted behind the eyes; the prothorax is vertically truncate at the apex; the elytra are strongly carinate at the base; and the mesostemal process is somewhat trans- verse and almost ; Zeugorrliinus is characterized as follows: "the head constricted behind the eyes, separated from the rostrum by a deep sulcus which is rather broadly interrupted in the middle but is
