recurved, second joint with appressed scales, teiminal joint rather shorter, 

 acute. Maxillary palpi rudimentary. Posterior tibia) clothed with long 

 hairs. Forewings with 2 from | or angle, seldom stalked with 3, 4 absent, 5 

 approximated, 7 and 8 stalked, 7 to costa, 9 absent, 10 and 11 remote. Hind- 

 wings somewhat over 1, ovate, cilia ^ ; 3 and 4 stalked, 5 somewhat approxi- 

 mated, 6 and 7 remote, diverging. 

 'O'X J^Vll .4t>3 Type ilL awcjsirias, Meyr. Formerly treated as a section of PtocTioryctis, but 



the discovery of a second species makes it desirable to give it generic rank. 



Metathrinca ophiura, n. sp. 



$. 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 brown ish-sufEused 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 sufJusedly 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, Eppaweja, 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 I 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. Antennse |, in $ 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 f 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 l\ 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
