Lepidoptera from the Khasia Hills. 363 



discal curved band, broad at the costa, which it does not quite 

 touch, sinuous, with several long dentations towards the outer 

 margin, and fines down gradually to the hinder margin near 

 the angle, which it does not quite reach ; the second and 

 fourth dentations the longest : hind wings with a thin white 

 and very sinuous discal line ; cilia of both wings white. 

 Underside dull black-brown, not glossed as in albicincta and 

 glaucopis; fore wing with a short white band on each side of 

 the discoidal vein ; the white toothed discal band broken up 

 and macular ; the white line of the hind wing broken up into 

 thin lunules. 



Expanse of wings 3^ inches. 



Jaintia Hills. Two pairs. 



Allied to N. glaucopis, but lacks the beautiful blue sheen 

 of that species. 



Nyctipao opkristigmaris, Hampson (Trans. Ent. Soc. 1895, 

 p. 305), is the male of N. gemmans, Guen. ; I have received 

 many of both sexes from Cherra Punji. There is often a 

 similar difference between the sexes in the species N. glaucopis, 

 Walker. 



Hypenidse. 



<$ ? . Olive-brown ; fore wing with an outwardly curved 

 indistinct subbasal line ; a postmedial erect and nearly straight 

 line, outwardly edged with ochreous ; halfway between this 

 and the margin is a sinuous dark line with pale outer edge, 

 and marked inwardly with black spots ; in some examples 

 there are also two large black spots on the inner side of the 

 postmedial line, and in one example the line runs through 

 these black spots, and there are black diffused streaks between 

 the lines ; a black spot at the end of each vein on the outer 

 margin : hind wings darker brown, unmarked ; cilia of both 

 wings brown, interlined with ochreous. 



Expanse of wings 1 -f a inch. 



Cherra Punji. Many examples. 



Allied to H. ophiusoides, Moore, and H. uniformis, 

 Hampson ; from the former it can be distinguished by the 

 postmedial line being straight : in ophiusoides there are two 

 acute outer dentations ; in uniformis this line inclines out- 

 wards and is not erect.
