68. Engytatus nicotianae (Koningsberger) (fig. 17, a, b). Leptoterna nicotianae Koningsberger, Mededeel. Lands Plantent. 64: 32, pl. 4, fig. 8, 1903. Cyrtopeltis (?) nicotianae Kirkaldy, Linn. Soc. N. S. Wales, Proc. 33: 377, 1908. New synonymy. Dicyphus nicotianae, Fulmek, Deli Proefstation, Bull. 25: 2, 1925. One specimen, Piti, May 2, and two specimens, Piti, April 30, on Nicotiana, Usinger; seven specimens, Yona, May 12, on Nicotiana, Usinger. I follow Fulmek in assuming that this is the species described by Koningsberger from Java, though the length is given as 4 mm. in the original description, whereas my series is uniformly about 3.5 mm. E. nicotianae may be separated from tenuis, aside from the distinctive male terminalia, by the dark dorsal pubescence, and by the third antenna! segment which is pale even at the base. Judging from the damaged female types, Kirkaldy's Cyrtopeltis (?) nicotianae from Fiji belongs here. Whether Froggatt's Dicyphus tabaci (Agric. Gaz. N. S. Wales 31: 715-716, figs., 1920) from Australia belongs here or elsewhere is impossible for me to determine from the brief description. I have seen nicotianae from Noumea, New Caledonia, on Datura, F. X. Williams.
