Expanse d IS, $ I'S to 2*0 inches. 



Hab. Sikkim. 



Near to Satadra hupola, Hewitson, many specimens of both sexes 

 of w^hich species, also from Sikkim, are now before me. S. singla d may- 

 be distinguished at once from that species by the much narrower and 

 more produced forewing, by the colour of the upperside being of a much 

 darker shade of purple, and both sexes by the violet- whitish powdering 

 of the hindwing on the underside. Allied also to 8. silhefensis, Hewit- 

 son, a female specimen of which from the typical locality is in the 

 Indian Museum, Calcutta. On the upperside of the latter the violet- 

 blue colour is far more extensive and lighter in shade, the underside is 

 also uniform bright brown throughout, not powdered with violet- white 

 as in S. singla. 



Plastingia noemi, n. sp., PL II, Fig. 15, (?. 



^ . Upperside black. Forewing with a fusiform chrome-yellow 

 streak on the costa from the base to nearly half the length of the wing, 

 a similarly-coloured streak placed below the median nervure and divided 

 by the submedian into two unequal parts, the lower portion the smaller, 

 extending to rather more than half the inner margin of the wing from the 

 base ; and with two or three subapical conjoined increasing spots, two 

 lengthened spots at the end of the cell placed one above the other, the 

 upper one the smaller, a triangular spot towards the base of the second 

 median interspace, a much larger one towards the base of the first, all semi- 

 transparent yellowish- white. Hindwing with a chrome-yellow patch placed 

 in the middle of the disc just beyond the cell, and divided by the black 

 nervules. Underside, forewing black, the costa narrowly, the apex very 

 widely, and a patch placed in the middle of the submedian interspace 

 chrome-yellow. The semi-transparent spots as above. Five rounded 

 small black spots placed in an outwardly-angled subapical series. Hind- 

 wing chrome-yellow ; the margin increasingly to the anal angle, then 

 decreasingly up the abdominal margin black. A subbasal spot, another at 

 the end of the cell, a series of eight spots placed round the cell, all black. 

 AntenncB black, the club yellow. Thorax and base of abdomen above 

 clothed with long greenish-ochreous hairs, the rest of the abdomen black 

 ringed with yellow, the thorax and legs beneath chrome-yellow. 



Expanse 16 inches.
