dark ochreous-fuscous, beneath' white. Abdomen dark fuscous, beneath 

 whitish-ochreous. Forewings subtriangular, costa moderately arched, apex 

 obtuse, termen somewhat rounded, rather oblique ; blackish-fuscous, basal area 

 sometimes ochreous or brownish more or less mixed with blackish ; four 

 transverse series of blue-leaden-metallic finely black-edged spots or marks, first 

 near base with an enlarged spot on basal portion of costa, two near together 

 before middle rising from whitish costal strigulse, and one before termen ; 

 a patch of ferruginous-ochreous suffusion on posterior § of costa, marked 

 with four small ochreous-white costal spots, of which the first originates an 

 oblique blue-leaden-metallic black-edged elongate mark : cilia ochreous-white, 

 with a black basal line, and blackish-grey patches at apex, middle of termen, 

 and tornus. Hindwings grey, thinly scaled, apex and termen suffused with 

 dark fuscous ; cilia pale grey, with dark fuscous subbasal line. 



Coorg (Newcome) ; Khasis ; from September to November, seven specimens. 



Tymbarcha, n. g. 



Antenna? in $ minutely ciliated. Palpi moderate, porrected, second joint 

 expanded with scales above towards apex, terminal joint short. Forewings with 

 costa angularly bent and prominent in middle, surface with slight tufts of 

 scales, in $ without costal fold ; 3 and 4 stalked, 5 approximated, 7 and 8 

 stalked, 7 to termen. Hindwings with 3 and 4 stalked, 5 approximated, 



6 and 7 closely approximated towards base. 



Tymbarcha cerinopa, n. sp. 



£. 13 mm. Head, palpi, thorax and abdomen pale whitish-ochreous. 

 Forewings elongate, costa abruptly bent in middle, so that the wing is much 

 widest at this point and narrows rapidly to either end, ciliated on and beyond 

 prominence to apex, apex obtuse, termen sinuate, short, nearly vertical ; 

 whitish-ochreous, veins more ochreous, strewn with small tufts of scales finely 

 sprinkled with blackish, tending to be arranged in transverse series ; basal patch, 

 a narrow central fascia starting from a small whitish spot on costa, and a streak 

 along posterior part of costa and termen suffusedly glistening silvery-whitish : 

 cilia ochreous- whitish, with a deep ochreous shade, at tornus suffused with 

 deeper ochreous and more fuscous towards tips . Hindwings pale whitish-grey- 

 ochreous , cilia ochreous- whitish. 



Khasis ; one specimen. 



Argyrotoxa, Stph. 



Antennae in $ minutely ciliated. Palpi moderately long, porrected, second 

 joi:it triangularly expanded with scales, terminal joint short. Forewings with 

 tufts of ia:sud scales on surface, in $ without costal fold ; 3-5 approximated, 



7 to termen. Hindwings with 3 and 4 connate or stalked, 5 approximated, 

 6 and 7 closely approximated towards base. 



Type A. bergmanniana, L. I find it desirable to reconstitute this genus 

 (which had been abandoned by myself and others), to include those species 

 which differ from Tortrix by the possession of scale-tnfts on the surface of 

 forewings, and from Oxygrapha by the terminal ending of vein 7 ; in other
