Pachjrhabda suspecta n. sp. 



O 10 mm. Head and thorax whitish-ochreous. Palpi whitish. Posterior 

 legs whitish, with dark fuscous rings at apex of tibiae and of tarsal 

 joints. Forewings very narrow, widest near base, thence narrowed to 

 acute apex ; 7 and 8 coincident ; whitish-ochreous suffused with greyish ; 

 dorsum suffused with ochreous-whitish anteriorly, with an oblique ochreous- 

 fuscous subdorsal strigula near base ; an indistinct median outwards-oblique 

 ochreous-fuscous transverse shade from a small dark fuscous mark on 

 middle of dorsal edge; some ochreous-fuscous suffusion in disc towards 

 apex: cilia ochreous-whitish. Hindwings whitish-grey cilia ochreous- 

 whitish. 



Java, Pekalongan (van Deventer); one specimen. 



Placoptila lucicincta Meyr. 



A cf, probably referable to this species, which was described from 

 Q only, has very large anal tuft of expanded whity-brownish hairs (quite 

 different from the longer projecting pencil of the Bornean cyanolychna), 

 and is also without the hair pencil of hindwings of cyanolychna; the 

 tips of cilia of forewings are whitish. 



Java, Tegal (Lucassen) ; one specimen. 



Chrysoxestis n. g. 



Head smooth, rounded; ocelli small, posterior; tongue developed. 

 Antennae nearly 1, basal joint elongate, slender, without pecten. Labial 

 palpi very long, recurved, smooth, slender, terminal joint longer than 

 second, acute. Maxillary palpi very short, filiform, drooping. Posterior 

 tibiae smooth with whorls of long projecting bristles at origin of spurs, 

 inner spurs extremely long, tarsi with very short bristles at apex of 

 joints. Forewings lb very long-furcate, 2 from near angle, 6 and 7 out 

 of 8, 7 to costa, 11 from 2 / 2 . Hindwings 3 / 4 , narrow-lanceolate, cilia 2 , / 2 ; 

 2 — 5 parallel, 6 and 7 stalked. 



A development of Xestocasis, from which it differs by 6 of forewings 

 rising (in one wing apparently from a point with 7) out of 8. 



Chrysoxestis lauta n. sp. 



Ç 12 mm. Head, palpi, and thorax shining dark bluish-grey. Abdomen 

 dark grey. Forewings narrowly elongate-lanceolate ; dark bronzy-fuscous;

 somewhat oblique slightly curved golden-metallic fasciae at 2 / 5 and 2 / 3 , 

 white on costal edge ; between these an elongate outwards-oblique iridescent
