and the whole hind margin broadly fuscous ; costa bright 

 yellow ; near the base are two broad brown spots, the 

 beginnings of two lines, which are angulated on subcostal, and 

 broadening out unite in forming the fuscous basal area ; a 

 third brown spot about the middle of costa gives rise to the 

 first line, which runs obliquely inwards to inner margin at 

 one third ; it is followed in the cell by a roundish hyaline 

 scaleless impression, which is in turn followed by a yellow 

 brown-edged discocellular marking, above which is a small 

 brown spot on costa, and beyond this a brown semiannulus ; 

 the fuscous margin is bounded inwardly by the exterior line, 

 which runs parallel to hind margin, forms a slight but distinct 

 angle opposite the cell, is incurved so as to touch the disco- 

 cellular mark, and then runs obliquely inwards to inner 

 margin about the middle : the dark margin contains a yellow 

 costal lunule before apex and a yellowish blotch above 

 anal angle ; fringe yellow, with brown apex. Hind wings 

 yellow, with base, discal spot, exterior line, and marginal 

 band brown ; fringe as in fore wings. Head, thorax, and 

 abdomen yellowish, marked with brown. Underside the same, 

 but duller. 



Expanse of wings 16 millim. 



One male from the Khasias. 



Thysanodesma eximtaUs, sp. n. 



Fore wings pale straw-colour, almost wholly suffused with 

 purplish fuscous, the only parts unsuffused being the costa on 

 either side of the exterior line, a small patch above anal 

 angle on hind margin, and a squarish space in the cell 

 between the two stigmata, and that is whitish and semitrans- 

 parent ; along the inner margin, especially between the two 

 lines, the suffusion is more sparse ; first line at one fourth 

 sinuous, dark fuscous ; exterior line at five sixths, starting 

 from dark costal spot, wavy and parallel to hind margin for 

 one third, then forming a rounded sinus, running in along 

 the first median, thickened below the discocellular and waved 

 to the inner margin ; first discal stigma roundish, fiattened, 

 just beyond first line; second oblong, flattened, beyond the 

 discocellular ; both dark-edged ; fringes dark fuscous in the 

 middle and at the anal angle, paler between and towards 

 apex ; a fine pale line at the base, followed by a dark fuscous 

 one and preceded by a blackish marginal line. Hind wings 

 the same, but the discal and costal areas paler, unsuffused. 

 Head, thorax, and abdomen dark fuscous, mottled with
