(3) OPS MELASTIGMA, de Niceville. 



Tajuria melastigma, de Niceville, Proc. Zool. Soc. Lond., 1887, p. 460, pi. xl, fig. 1, male; 

 idem, id., Butt, of India, vol. iii, p. 379, n. 935 (1890). 



Habitat : Sikkim ; Khasi Hills ; Burma ; North Kanara ; Nilgiri 

 Hills. 



Very near to 0. ogyges, de Niceville, but in the male on the upper- 

 side the blue coloration is different, of a darker shade, and never 

 iridescent emerald-green in any light. The " male-mark" is still more 

 prominent than in 0. ogyges, is more quadrate in form, does not extend 

 into the discoidal cell, and posteriorly reaches the first median nervule 

 only instead of ending midway between the first and second median 

 nervules. 



27. TAJURIA TURA, n. sp., PI. P, Fig. 39, $, 

 Habitat : Battak Mountains, N.-E. Sumatra ; W. Java. 

 Expanse : £,1*6 inches. 



Desobiption : Male. Uppebside, both wings rich shining blue. 

 Cilia cinereous. Forewing with the costa up to the subcostal nervure, 

 the apex very widely (its inner edge very irregular), the outer 

 margin decreasingly black, at the anal angle the black colour is re- 

 duced to a mere thread. Hindwing with the costa and apex somewhat 

 broadly fuscous ; an anteciliary black thread ; the anal lobe small and 

 black, with a few turquoise-blue scales posteriorly, and a dull ferruginous 

 line anteriorly ; abdominal margin broadly whitish ; tails black tip- 

 ped with white. Undebside, loth wings pale French-grey ; a fine darker 

 line closing the discoidal cells ; a similar discal line, on the forewing 

 commencing at the costa, ending on the submedian nervure, approach- 

 ing the outer margin posteriorly, slightly outwardly curved, in the 

 hindwing anteriorly straight, posteriorly zigzag and recurved 

 to the abdominal margin. Hindwing with an oval deep black spot 

 in the first median interspace close to the margin, anteriorly with a 

 large patch of clear yellow ; the anal lobe bearing an oval deep black
