latter they are described as being nearly alike. The three black 

 marginal spots from the anal lobe on the upperside of the hind wing 

 are also absent in T. albiplaga in both sexes. 



A single pair of this very distinct species is in Mr. Otto Moller's 

 collection. 



Tajuria melastigma, n. sp. (Plate XL. fig. 1, d .) 



Hah. Sikkim, Nilgiris. 



Ejfpanse. rf" 1'5 inch. 



Male. Upperside : both wings cerulean blue ^. Fore wing 

 with the costal, the apical half of the wing, and the outer margin 

 decreasingly to the anal angle black ; a large quadrate shining 

 black " sexual mark " on the disk, bounded on two sides by the 

 discocellular nervules and the first median nervule. Hind wing 

 with the outer margin verv narrowly black, widening at the apex ; 

 the abdominal margin whitish ; the anal lobe and inner tail dull 

 reddish, the outer tail black, both tails tipped with white. Under- 

 side : both wings dull pinkish. Fore wing with the inner margin 

 somewhat broadly greyish ; a discal straight narrow deep Indian- 

 red line, outwardly defined with whitish, from near the costa to the 

 submedian nervure ; an extremely obscure pale fascia near the 

 margin. Hind wing with the discal line in continuation of that on 

 the fore wing, the portion between the median nervules very irre- 

 gular, from the third median nervule oblique to the abdominal 

 margin ; the anal lobe marked with a rust-red spot, crowned 

 obscurely with orange ; a smaller very obscure spot on the first 

 median interspace, between which the ground is obscurely sprinkled 

 with white scales ; two indistinct series of dark spots between the 

 veins above the second median nervule on the margin ; an ante- 

 ciliary fine dark line. Cilia fuscous throughout. Body blue above, 

 pale red below, whitish at the sides. 



T. melastigma has no secondary male sexual characters between 

 the wings, and so far as I am aware the peculiar shining black 

 quadrate patch on the disk of the fore wing on the upperside is 

 unique amongst Indian Lyceenidae. Judging from Hewitson'a 

 figure alone it is closely allied to his lolaus ister, the type of which 

 is from " India," and is a female ; T. melastigma may be the 

 hitherto unknown opposite sex of that species. 



The type and only perfect specimen of T. melastigma is in the 

 collection of Mr. Otto Moller. I have received a single male fore 

 wing of this species from Mr. G. F. Hampson, collected iu the 

 Nilgiri Hills, South India. 



Zephyrus pavo, n. sp. (Plate XL. fig. 11, ? .) 



Hab. Bhutan. 

 Exjjanse. 2 1"35 inch. 



Female. Upperside : both wings black. Fore wing with the 

 costa somewhat widely, the apical third of the wing, and the outer 



^ Of almost the exact sliade of the common " Polyommatus " cleohis of 

 Godart.
