An Old World Tropic species, its migratory specimens can appear in the southern areas ol tlie Palaearctic Region; an agricultural pest. Argyrogramma signata (Fabricius, 1794) (Entomologica Syst., 3(2): 81 - Noctua) Examined material: 1 female, Prem waterfall, 15 km S of Da Lat, 19. X. 1988, leg. Mahunka, Oláh and Vásárhelyi. An Old World Tropic species, similarly to the preceding one, but more close to the southern ranges and less frequent. Ctenoplusia limbirena (Guenée, 1852) (Noct. II: 350 - Plusia) Examined material: 1 male, Da Lat, 1500 m, 14. X. 1988; 4 males from same locality and data, 15. X. 1988; 1 female from same locality, 16. X. 1988; 1 male, 1 female from same locality and data, 17. X. 1988; 1 male, 1 female from same locality, 19. X. 1988; all specimens were collected by Mahunka, Oláh and Vásárhelyi. This species has a widespread distribution in the Palaeotropic Region, being an agricultural pest in several places. It appears more scarcely in India and the Malay Peninsula; new to the fauna of Vietnam. Ctenoplusia albostriata (Bremer et Grey, 1853) 'Beitr. Schmett, north. China, p. 18. - Plusia) Examined material: 1 male, Vinh Phu, Lap Thach, 20.1. 1986; 1 female, Vinh Phu, Tarn Dao, 1200 m, 13.X. 1986; 1 male. Cue Phuong, 400 m, 17.X. 1986; 1 male, Prov. Vinh Yen, Tam Dao, 840 m, 9. V. 1987; 2 males, Da Lat, 1500 m. 14. X. 1988; 2 males from same locality, 16. X. 1988; 1 male from same locality, 17. X. 1988; 3 females from same locality, 19. X. 1988. Albostriata is one of the most widespread Plusiinae species, its area extending from the Soviet Far East and Japan throughout the Indo-Australian zone to Australia and S America (Chile). Its generic relegation is doubtful, as it possibly belongs - with its related species, C. oxygramma (Hübner-Geyer, /1832/), to a line, evolved distinctly from the typical Ctenoplusia species. Ctenoplusia (Acanthoplusia) microptera sp. n. (Plate: 3-4) Holotype: male, "Ha Noi, Quang Ba, Ho Tay (West Lake), 28.X. 1986, leg. Mészáros, Oláh and Vásárhelyi", slide No. 3009 Ronkay; deposited in coll. Hungarian Natural History Museum, Budapest. Paratypes: 1 female from same locality and data; 2 males, Hoa Binh, 100 m, 23.

Mahunka, Oláh and Vásárhelyi; 3 males, Vietnam, Hanoi, 4-10. XI. 1963, leg. Manninger; 1 male, Vietnam, Hanoi, 40 m, 28. X. 1963, leg. T. Pócs; 1 male from same locality, 7. VIII. 1963, leg. T. Prtcs. The specimens are deposited in coll. HNHM, Bp. and the British Museum (N.H.). 1 <*>, Hanoi, 30.111. 1986, leg. Kuznetsov, coll. Zool. Institute, Leningrad.

Head and thorax dark brown with some violaceous tinge, tegulae with violaceous-whitish edges. Abdomen greyish-brown, dorsal crest consists of three blackish-brown tufts, ventral side with long ochreous hairs at base; coremata well-developed, dark brownish. Fore wing triangular, ground colour dark chocolate-brown with rosy-violaceous shade and intensive bronze-metallic iridescence. Antemedial line double, filled with rosy-white, defined with rosy-violaceous scales. Basal area with some black spots, basal line usually visible. Orbicular spot flattened, carneous, filled with brown and often with some blackish. Figs 22-25. 22-23 - Ctenoplusia (A.) agnata Staudinger (22 - No. 2908, Vietnam, 23 No. 3007, Vietnam). 24-25 - C.
