INDIAN MICRO-LEPIDOPTERA. 439 



Thiotricha, Meyr. 



This genus, characterised by the long antennal ciliations of $ , and absence 

 of veins 4 and 8 of forewings, includes ten Australian species and two from 

 New Zealand. I have already referred to it animosella, Walk., and described 

 two Indian species ; I now describe fifteen more. 



Thiotricha animosella, Walk. 



(Gelechia animosella, Walk. 1022.) 



Muskeliya, Ceylon ; N. Coorg ; Khasi Hills ; in February, March, and June. 



Thiotricha glenias, n. sp. 



£9. 8-10 mm. Head, palpi, antenna?, thorax, and abdomen silvery- white ; 

 palpi in $ with expansible fringe of long fine hairs on second joint above. 

 Forewings elongate, very narrow, parallel-sided, round-pointed ; 6 and 9 out of 

 7 ; silvery-white, more or less tinged with ochreous ; apical § orange-ochreous 

 anteriorly suffused ; a grey mark from dorsum before tornus, angulated inwards 

 near dorsum, then outwardly oblique, reaching more than half across wing, a 

 round black dot at apex, and another on termen, each preceded by a whitish 

 dot : cilia pale whitish-ochreous, round apex with basal half orange limited by a 

 grey line. Hindwings h, cilia 6 ; whitish-grey, thinly scaled, apex tinged with 

 orange ; a blackish apical dot : cilia pale whitish-ochreous, at apex with post- 

 median blackish-grey dot. 



Maskeliya, Ceylon, in December, January, and May ; four specimens (Pole). 

 Allied to animosella, but grey dorsal mark differently formed ; and also 

 characterised by the expansible fringe of palpi, which is absent in animosella. 



Thiotricha centritis, n. sp. 



$. 11 mm. Head, palpi, antennae, thorax, and abdomen shining ochreous- 

 whitish ; palpi with long fine expansible hairs on second joint above. Fore- 

 wings elongate, very narrow, gradually attenuated posteriorly, round-pointed ; 

 6 and 9 out of 7 ; shining pale whitish-ochreous ; apical third ochreous-orange, 

 anteriorly suffused ; some grey suffusion on dorsum before tornus and on middle 

 of termen ; a large round black apical dot, edged with white in cilia, cilia 

 otherwise whitish-ochreous, round apex with a grey median line. Hindwings 

 i, cilia 6 ; whitish-grey, apex slightly tinged with orange ; a blackish apical dot : 

 cilia whitish-ochreous, at apex with postmedian blackish dot. 



Palni Hills (6,000 feet) ; one specimen (Campbell). 



Thiotricha clidias, n. sp. 



gy, 8—11 mm. Head, palpi, antennae, thorax and abdomen ochreous- 

 whitish ; palpi in £ with short expansible hairs towards apex of terminal joint 

 above. Forewings elongate, very narrow, gradually attenuated, round-pointed ; 

 6 and 9 out of 7 ; in £ ochreous-whitish, in $ pale greyish-ochreous ; apical 

 third orange, anteriorly suffused; costal edge posteriorly blackish, marked 

 towards apex with three irregular white or whitish dots ; in $ sometimes grey 

 marks along dorsum towards \ and middle ; two blackish streaks from about 

 tornus, acutely angulated inwards near dorsum, then very oblique outwards, 

 reaching § across wing, separated with whitish ; beyond these a whitish terminal
