whitish with fuscous markings (the specimens are not in good 

 condition and they will be more recognisably desci-ibed as fuscous 

 with a sinuate creamy-white dorsal stripe) ; the paler colour, which 

 is most noticeable on the dorsum, leaves the base at about one- 

 third the wing-Avidth descending obliquely to the fold, it is thence 

 slightly sinuate upwards, thence descending it ascends triangularly, 

 and again obscurely, thence occupying the terminal area of the 

 wing (and perhajts irrorating the subcostal portion) ; there is 

 a strong short black streak from the base to above the flexus, 

 and along the dorsum are some irregular dark spots ; above the 

 pale dorsal portion of the wing the fuscous colouring becomes 

 more concentrated, appearing as a length-streak from the base ; 

 oi'iginating from the costa are several transverse dark markings, 

 the most distinct being a cloudy spot at about two-thirds, below 

 which is a cloudy patch at the end of the cell ; there is a dark 

 (somewhat triangular) spot at the apex and others along the costa 

 and termen ; cilia greyish ochreous, with a cinereous dividing 

 line near their base. Exp. al. 23 mm. Hindwings plumbeous ; 

 cilia greyish fuscous, with a dark dividing-line near their base. 

 Abdomen cinereous. Legs pale cinereous, tarsi blackish, with 

 narrow whitish bands above. 



Type S. 



Hah. Tibet, Gyantse, 13,000 ft., vi. 1904 {H. J. Walton, Tibet 

 Expedition 1905 : 172). Two specimens. 



Intei'mediate between senilella Zett. and annulatella Crt. ; in 

 size and coloration more nearly resembling the former, but in 

 pattern more like the latter, from which it differs in the pale dorsal 

 marking being less abruptly (less angularly) bent upward and 

 being divided by a black length -streak from the base — these would 

 appear to be good diagnostic characters, but the poor condition of 

 the specimens makes the matter uncertain. 



TOETRICIDiE. 



249. Enarmonia Hb. 



1990: 1. Enarmonia vexilla, sp. n., Drnt. 



Antennce (broken) fuscous. Palpi whitish cinereous. Head 

 and Thorax cinereous. Forewings appearing greyish, but actually 

 chalky- white with fuscous markings and irrorations ; a basal 

 patch terminated at about one-third by a darker sooty marginal 

 line, which leaving the costa obliquely outward becomes concave 

 and thence projects strongly along the fold, receding obliquely 

 backward to the dorsum — this basal patch is slightly darker than 

 the rest of the Aving and contains some darker transverse markings ; 

 before two-thirds a somewhat similar dark fascia includes a chalky, 

 transversely irrorated, band ; beyond this the wing is whiter in 

 appearance, and on the costa are three distinct fuscous triangidar 

 spots separated by the white ground-colour and succeeded by a 

 patch of a more creamy colour ; from the last dark marking
