On some new or little known Indo-Malayan Noctuids (Lepidoptera Heterocera, family Agrotidae)
I. Trisula celebensis nov. spec. (Pl. I fig. 5 ♂). ♂. A large species, near T. variegata Moore in Horsfield-Moore (Cat. &c., II, 1858—59, p. 420, ♂♀, pl. 12a fig. I ♂, pl. 22 fig. I (larva), Ia (pupa): India). General coloration, however, more variegated, vivid, light greyish brown, with a slight coppery gloss, mixed with white on forewing chiefly near middle of costa. Transversal lines on forewing darker, strongly dentate and curved, the outer forming an irregular, black, subapical streak. Reniform irregularly circular. Hindwings greyish, with dark cloudy bands, a dark patch on dc and with some reddish brown and light grey near anal angle. Underside paler, both wings darker clouded with broad bands and a black patch on dc. Palpi yellowish brown, except the tip which is darker; pectus yellowish brown, abdomen nearly white. ♀ unknown. 2 ♂♂, holo- and paratypus, 75 and 80 mm, both from Sidaonta, Palu, W-.Celebes, 7. 37, leg. Kalis, coll. Wageningen. The genus Trisula Moore, till now, only contains two species, viz. the above mentioned variegata Moore from India and Ceylon, and the smaller T. dudgeoni Hps. (Hampson, Moths, IV, 1896, p. 530, ♂) from Bhutan. It is, therefore, interesting here to record a third species from Central Celebes, which replaces the continental variegata in this island. 2. Acronycta ardjuna nov. spec. (Pl. II fig. 5 ♂). ♂. A distinct species, easily separable from all other known species of this genus by its general appearance. Forewings white, with prominent
