230 Some apparently new Species and Forms of Noctnidae 



Fore wing violet-white, with a patch of cupreous olive-brown on 

 medial area behind the cell, and cupreous olive-brown shading proxi- 

 mally to the subterminal line. Subbasal, antemedial and postmedial 

 lines double, waved, oblique, the subbasal ending at fold, the ante- 

 medial obsolescent (bent outward?) from costa to M, the postmedial 

 bent outward on SM 2 ; pale mark behind cell Y-shaped, very broad 

 at M ; an olive-brown line from costa to M, proximally to the post- 

 medial line ; subterminal line near termen to behind SC 4 , then bent 

 inward, leaving the termen conspicuously pale except for a strong, 

 diffused dark spot on E 3 ; a fine dark terminal line, broadening 

 between the veins ; fringe white with fine dark shading at middle and 

 tips and with dark shading on distal half opposite the veins. 



Hind wing brownish-white thickly irrorated with brown, the 

 proximal half a little paler than the distal ; traces of a dark discal spot ; 

 fringe as on fore wing. 



Underside of fore wing greyish-brown, of hind wing whitish-brown, 

 traces of a dark postmedial line, especially on the hind wing ; hind 

 wing with a discal spot ; both wings with a fine dark terminal line ; 

 fringes as above. 



Manusela, 6,000 feet, October to December, 1919, one 8 . 



Belongs to Section IV, A, a, b 1 , b 2 , of Hampson. Perhaps nearest 

 to subsidens Wlkr., from Australia. 



OPHIDEEINAE. 



46. Syp?ia achaeopsis sp. nov. 



8 , 48 — 55 mm. 



Head, palpus, thorax and antennal shaft ochreous-brown, the head, 

 tegulge and patagia more or less shaded with dark-brown ; abdomen 

 above ochreous-white (occasionally tinged with fuscous) with the crests 

 deeper ochreous ; abdomen beneath, pectus and legs whitish. 



Fore wing typically with the basal two-fifths purple-brown, the area 

 between medial and postmedial lines pale-ochreous or greenish-ochreous 

 and the distal third ochreous-brown tinged with rufous. Lines some- 

 what as in achaeoides Wlkr., from Celebes, but the antemedial much 

 more strongly bent outward behind costa, the medial almost straight 

 (not excurved behind M, as in achaeoides) and the postmedial bent 

 outward at costa (not just behind costa) and forming two separate wide
