Metathrinca ophiura, n. sp. 



ft. 13-15 mm. Head fuscous, face prismatic-white except on margins. 

 Palpi whitish, second joint infuscated towards base, terminal joint anteriorly 

 suffused with dark fuscous. Antennae blackish, pectinations 6. Thorax white, 

 posterior extremity with a blackish spot. Abdomen white, segments banded 

 with ferruginous-reddish. Forewings elongate, moderate, costa strongly arched, 

 apex obtuse, termen slightly rounded, oblique ; 2 and 3 closely approximated 

 towards base or stalked ; shining white ; an irregular moderate pale greyish- 

 silvery partially brownish-suffused fascia extending round apical fourth of 

 costa and upper half of termen, thence suddenly curved inwards and ter- 

 minating on dorsum before torn us, edged with blackish on costal portion and round 

 apical margin, and suffusedly blackish-edged towards dorsum, anterior edge in 

 middle emitting a cloudy fuscous streak-like projection : cilia white, at apex 

 with a black median vertical mark, beneath this with two fuscous transverse 

 bars. Hindwings whitish ; cilia white. 



Muskeliya, Puttalam, Eppawela, Wellawaya, and Galle, Ceylon, in April. 

 May, September and December (Alston, Pole, Green, Fletcher) ; six specimens. 

 Exceedingly like ancistrias, but much smaller ^my smallest ancistrias is 19 mm., 

 the small Puttalam insect referred to in my description being really ophiura), 

 and best distinguished by the neuration : in ancistrias vein 2 of forewings rises 

 from f of cell, fairly remote from 3, whilst in ophiura 2 and 3 are closely 

 approximated, rising from angle of cell, or even stalked. 



Linoclostis, n. g. 



Head with appressed scales, sidetufts spreading ; ocelli present ; tongue, 

 short. Antennae f, in ft bipectinated, apex simple. Labial palpi long, recurved, 

 second joint with appressed scales, terminal joint much shorter, acute. Maxil- 

 lary palpi rudimentary. Posterior tibiae clothed with long hairs. Forewings 

 with vein 2 from j£ of cell, 3 and 4 stalked from angle, 5 closely approximated 

 at base, 6 absent, 7 and 8 stalked, 7 to termen, 9 absent. 10 and 11 remote. 

 Hindwings somewhat over 1, ovate-trapezoidal, cilia § : 3 and 4 short-stalked, 

 5 parallel, 6 and 7 remote, diverging. 



Linoclostis gonatias, n. sp. 



$ . 23 mm. Head and thorax white, lower part of face infuscated. Palpi 

 fuscous. Antennae dark grey. Abdomen ochreous-grey-whitish. Forewings 

 elongate, somewhat dilated posteriorly, costa moderately arched, apex obtuse, 

 termen slightly rounded, oblique ; shining white ; costal edge dark fuscous 

 towards base ; a slender fuscous subterminal line from § of costa to torn us, 

 almost right-angled in middle ; a slender ochreous-brownish line along apical 

 sixth of costa, cilia beginning abruptly at its origin : cilia white, with a fine dark 

 fuscous line at \, on outer half with a light brownish patch at apex and two 

 spots below this. Hindwings grey-whitish ; cilia white. 



Khasis, in June ; one specimen. A ft from Java, almost certainly of the 

 same species, has palpi white, antennae black, lateral margins of face pale 

 brownish, expanse 17 mm.
