? . Only (lifFers from the otlier sex in being more golden ; 

 the thorax very bright, with distinct black stripes ; the 

 abdomen with only six bands ; the wings with the hyaline 

 spots larger. 



Expanse of wings Ij^q-I/^t inch. 



Khasia Hills. 



Allied to S. Grotei^ Moore, from Yunnan, the type of 

 which I have carefully examined ; but the extremity of the 

 abdomen is black in both sexes, atid not yellow as in Groteij 

 and the costa of the hind wing is black, and not orange; it 

 is nearer to S. suhmartjinalis^ Walker ; the hyaline spots are 

 very similarly disposed, but the submedian interspace on fore 

 wings in that species is not wholly hyaline, and the outer 

 portions of the wing are golden, whereas in this species they 

 are black. 



Family Geometridae. 



Subfamily Menocteniin^. 



Nearcha ophla^ nov. 



^. Top of head and shaft of antennse white, branches 

 black; body and wings with the ground-colour ochreous 

 grey, nearly white, irrorated with black atoms, theirroratioiis 

 thicker on the fore than on the hind wings, making them 

 darker-coloured : fore wings with a black ringlet at end of 

 cell, indications of an interior line ; a discal black line with 

 black points ; in some examples the space between is fiUed 

 in with densely packed irrorations, making a broad medinl 

 band, also submarginal and mai'ginal bands of pale blackish 

 spots joined together, the margin with black points: the liiiid 

 wing has a blackish spot at the end of the cell, a central line 

 corresponding to the discal line of the fore wings, submarginal 

 and marginal bands, and marginal black points as in the 

 fore wings, but paler. Underside whitish, with some of the 

 markings showing through the wings. 



? . Like the male, but generally darker. There are eleven 

 examples in the B. M. and five in the O. M., all collected 

 together and mostly differing a little one from the other. 



Expanse of wings 1 j\, inch.
