slightly dilated, costa gently arched, apex obtuse, termen almost straight,

 spots below middle at g and | indicated by ochreous-f uscous suffusion or dark

Barberyn Island, Ceylon, in February (Fletcher) ; two specimens. Easily

 Bactra tornastis, n. sp. 



(^9- 14-16 mm. Head and thorax whitish-ochreous, sometimes tinged 

 with brownish. Palpi 2, whitish-ochreous, with broad median band of

Nawalapita, Ceylon, in January (Pole) ; Gooty (Campbell) ; Coorg, 3,500 feet, 

 in October (Newcome) ; four specimens. The only species which has the 

 termen of forewings rounded in ^ , in all the rest it is straight or sinuate. 

 Poli/chrosis, Rag. 



This is the genus hitherto passing as Chrosis, Gn, It differs from Bactra by 

 the crested thorax, from Proschistis by 6 and 7 of hindwings being connate or 

 stalked, from Argyroploce by the separation of 3 and 4 of hindwings, I have 

 described one species, epkippias, and now give four more. 

 Polychrosis cerata, n. sp. 



^9- 10-12 mm. Head and thorax pale yellow-ochreous. Palpi with long 

 rough spreading scales, pale ochreous, more or less sprinkled with dark fuscous 

 towards base. Abdomen rather dark grey. Forewings elongate, rather narrow, 

 posteriorly slightly dilated, costa gently arched, apex obtuse, termen little 

 rounded, somewhat oblique ; dark fuscous, with purplish-leaden reflections, 

 with the base of all scales fuscous-whitish, forming fine transverse striae ; costa 

 with about six oblique blackish fuscous strigulase, and sometimes mixed with 

 yellowish between these ; base sometimes mixed with ochreous-yellowish ; large 

 oblique irregular ochreous-yellow blotches from dorsum about ^ and beyond
