at vein nu, lower part straight, slightly oblique, defined with a wide, dark violaceous stripe on inner side. Terminal line white with some small dark, quadrangular spots from apex to vein ci^, cilia dark brown. Hind wing whitish, inner area nearly pure, cellular lunule very small and pale, marginal field wide, dark brown with slightly diffuse inner side, transversal line absent or represented by some pale spots on veins, terminal line dark brown, cilia white, spotted with brown. Underside of fore wing brownish, cellular lunule and transversal line slightly visible, marginal area somewhat lighter, costa with some whitish spots at apex. Underside of hind wing whitish, costal and marginal fields with brownish suffusion, veins covered with brown. Cellular lunule stronger than on upper side, transversal line a diffuse stripe. Cilia as on upper side. Male genitalia (Figs 11-13): uncus long and slender, pointed, tegumen moderately high and wide, less sclerotized, vinculum narrow, elongate without terminal dilatation, saccus membranous. Fultura inferior scutelliform, valvae elongate with nearly parallel margins, cucullus wide, apex rounded. Harpe short, finger-like, sacculus narrow, clavus very long and arcuate, its basis membranous. Aedoeagus moderately long and thick, cylindrical, vesica rather difficult in structure, proximal part a short tube, finely granulöse, medial part dilated to a wide and semiglobular sac, some parts of it rugulose or slightly folded, with two small diverticles. Distal part a very special, rugulose sac like a mooseantler; cornuti absent, basal part with a sclerotized ribbon on ventral side, distal part of it upturned and slightly dilated. Specific differences and taxonomic position — The new species is very closely related to nigriluna (WALKER, 1857) but is essentially smaller in size and it has a series of differential characters in both of external and genitalic features as follows: in case of the new species the two spots of the stigma are conjoined, the bronze-cupreous shine and irroration is strongly reduced, the outer third of the median area is much lighter with a stronger medial line. The inner area of the hind wing of noona is lighter with only very slight darker suffusion, the cellular lunule is small or obsolete, the transversal line is reduced. The related nigriluna has the stigma consisting of two distinct spots (studied on nearly one hundred specimens from several localities), the bronze-reddish irroration is much stronger, the outer third of the median area is darker with more obsolescent medial line. The inner area of the hind wing is strongly suffused with brownish, the cellular lunule and the transversal line are well discernible. In the configuration of the male genitalia the new species has characteristically narrower vinculum without large and rounded extension terminally, which is present the case of nigriluna (Figs 14-16), the valvae of noona are less elongate and with wider apical part than in the case of nigriluna. The new species as far as known is an allopatric sibling species of nigriluna as the former is known only from the Philippines since the latter is a relatively widespread species from S China and S of Japan to New Guinea. 2. FAUNISTICAL RECORDS WITH SOME TAXONOMIC COMMENTS A) The material of the Noona Dan Expedition In 1961 an unusual Danish zoological expedition was organized which collected large entomological material in several parts of the Indo-Australian Region. The collecting localities, the methods and other circumstances are given in sufficient details in PETERSEN (1966). The Plusiinae material of this expedition contains 11 species, one of them is new for science. The list of the species and the data are listed below. Argyrogramma signata (FABRICIUS, 1792) — New Ireland, Lemkamin, 28 çfçf (10 April 1962, 2'fçf, 12 April, 7 çfçf, 17 April, 12 çfçf, 21 April, 7 çfçf); Bismarck Isl., New Britain, Yalom, 1000 m, 8 May 1962, 1 O. Chrysodeixis heberachis (STRAND, 1920) (Figs 8-9) — Philippines, Palawan, Mantalingajan, Pinigisan, 600 m, 3 Sept. 1961,2 çfçf. — This interesting species was described from Formosa ( = Taiwan) and it has also been found in the southern part of Japan (SUGI et al. 1982). The data from the Philippines are represent the southernmost locality of this interesting species which is closely related to the New Guineán C. kebeae (BETHUNE-BAKER, 1906); new for the Philippines. Chrysodeixis acuta (WALKER, 1857) — Philippines, Palawan, Brokes Point, Uring Uring, 18 Aug. 1961, 1 f.
