Kxpaiise of wings : 38 mm. 



<$ d from the Khasias. 



Distinguished, over anil alioM' tlic ilift'crence in outline of forewings, from S. 

 maculosatu liv the brown costal lilotehes, the more angnlated exterior line, and the 

 non-transparency of the white ground-colour. 



97. Semiothisa maculosata sp. nov. 



Foreivings : opalescent white, semi-transparent, containing a profusion of drali, 

 and ochreous olive, more or less coalescent, roundish spots ; the veins ochreous yellow ; 

 ba.sal line at one-fifth, dull fuscous olive, angled on subcostal and submedian veins, 

 with some blackish .-scales above the submedian ; an irregular, bent, oblique, thick 

 central shade, dull fuscous, with black scales on the submedian and geminated 

 below the median ; some black scales on the discocellular at its extremities; exterior 

 line Nellowish ochreous, starting from a dark costal spot at two-thirds, cur\-ed ojipositi- 

 the cell, and then running nearly parallel to hindmargin, and preceded by a narrow, 

 yellowish ochreous shade; this line bisects a roundish black blotch on the upper 

 radial, and a larger, more quadrate, blotch extending from the lower radial to the 

 second median ; marginal area beyond the exterior line fuscous olive, varied with a 

 congeries of black and yellowish scales along lower half of hindmargin ; sidjmarginal 

 line undulating from before apex to anal angle, whitish yellow, but forming irregular 

 tvhite spots at apex, and one larger white spot obliquely below it ; fringe fuscous 

 olive, with a row of black spots at base between the veins. 



Hindwings : with central and outer line as in forewings, the outer line passing 

 through only one black blotch, extending over the second and third medians; .sub- 

 marginal line pale, nearly straight from apex to anal angle, preceded liy a thick 

 fuscous olive shade ; marginal area fuscous, mottled in the middle before the slight 

 tail with white and black scales. 



Palpi, face, antennae, and collar ferruginous; thorax and abdomen dull whitish ; 

 basal segments of abdomen with double black spots ; underside of wings white, with 

 the spots and all the lines and shades dark brown. 



Kx|)anse of wings : 38 mm. 



Distinguished from S. brwn'iieatu, to which it bears great superhcial resemblance, 

 by the more obliipie hindmargin of forewings, scarcely perceptibly elbowed at tht- 

 end of the third median, and the more produced and acute apex. 



Si from the Khasias. 



98. Semiothisa penumbrata sp. nov. 

 Foreu'ini/s: .shining pale grey, thickly dusted with olive fuscous atoms; first line 

 slender, brown, vertical, at one-fourth, slightly curved below costa and above inner 

 margin ; an otilique brown streak from middle of costa just touches the slender brown 

 discal linear mark: a small brown spot on the median nervure and first median 

 uervule just beyond their point of separation, and another on the submedian exactly 

 below them; exterior line whitish, strongly curved below costa and slightly curved 

 above inner margin, running in the main parallel to the liinduiargin ; on the costa it 

 is preceded by a liroadish oblique brown-black streak, which does not pass beyond the 

 upiier radial, and curves up to the costa shortly before apex, so forming a rounded 

 triangular costal mark with a [)aler centre : a brown-black spot in midwing is dixided 

 into four parts by the exterior line and the tliird median nervule ; marginal space
