Images reproduced by kind permission of the Trustees of the Natural History Museum, Lon- don. la a triangular, curved, cap-like plate, its tip pointing dis- tally, with a pair of short, narrow processes arising from the proximal corners and directed caudally. Juxta a round plate, with a v-shaped incision with irregular margins dor- sally. Saccus narrow, strongly elongate, rounded distally. The aedeagus straight, club-shaped, with a stout proximal and a narrow distal half, the vesica with an elongate, se- mi-cylindrical sclerotization and a small group of cornu- ti, a long, curved, distal one and 3^4 distinctly smaller ones, arising from a common base. Bulbus ejaculatorius moderately large, about half the length of the aedeagus. Male genitalia of specimens from N Thailand a little small- er and slightly differing to those from Sumatra in the length-proportions of the saccular processes (Fig. 20). Female similar to male, wingspan 35-37 mm, length of forewing 19-21 mm, with forewings a little broader and termen more strongly curved. Pectinations of antennae about one fifth shorter than in males and a little narrow- er. Material studied. Type material. Holotype, cf, [Peninsu- lar Malaysia], Bukit Kutu, Selangor, April 1915, 3457'; coll. NHM (see Figs 16-18). J. D. Holloway (London, pers. comm.) mentioned two more specimens from Peninsular Malaysia in coll. NHM, but Prout (1923) ob- viously only had one specimen at hand when he described this species ( the holotype).
