C. ahasa^ C. lavendularis, C. la?ika, 0. singalensis, and G. limhatus all 

 apparently belong to this group, but the absence of specimens makes it 

 impossible to place them in their proper places in the key. 



3. Ctanieis placida, n. sp. (Plate I, fig. 8, ^ .) 

 C. placida, Moore, M. S. 



Hab. Sikkim ; Sibsagar, Upper Assam {S. E. Feal). 



Expanse : <? , 1*1 to 1*4 inches. 



Description : Male. Upperside, loth ivings rather deep lavender 

 blue. Forewing with the costa very narrov7ly, and the outer margin more 

 widely but decreasingly to the hinder angle black. Hindwing narrowly 

 black, the inner edge of the black border lunulated, sometimes reduced to 

 black spots between the nervules, and a black anteciliary line. Underside, 

 hoth wings white, slightly tinted with blue. Forewing with a fine disco- 

 cellular streak defined outwardly with whitish ; a discal series of five or 

 six more or less irregularly shaped and placed spots ; a submarginal lunu- 

 lated line, marginal spots and anteciliary line. Hindwing with three sub- 

 basal black spots ; a faint slender disco-cellular line ; a discal very sinuous 

 series of eight spots, the upper one on the costa and the lower one on the 

 abdominal margin deep black and the most distinct ; marginal markings as 

 on the forewing. Cilia white on both sides. 



Next to C. puspa, this seems the commonest Cyaniris in Sikkim ; I 

 took it at various elevations in October, and Mr. Otto MoUer has taken it 

 in large numbers in the Spring. The males are very constant, but I have 

 not seen the female. 



C. placida is very close to, if not identical with, the Lyccena cagaya 

 of Felder (Reise Novara, Lep., p. 278, no. 347, pi. xxxiv, figs. 11, 12 ^, 13 

 $ , 1865, from Luzon). In C. cagaya the marginal spots on the upperside 

 of the hindwing in the male are more prominent than in G. placida. 



4. Ctanieis dilectus. (Plate I, fig. 5, ^ .) 



Polyommatus dilectus, Moore, Proc. Zool. Soc. Lond., 1879, p. 139. 



Hab. Simla ; Nepal ; Sikkim ; N. Cachar ; Sibsagar, Upper Assam 

 <S. E. Feal) ; and Upper Burma (brougJit ly the Tunan Expedition). 



Expanse : $ , 1-05 to 1-40 ; ?, 85 to 1-35 inches. 



Description : Male. Upperside, loth wings pale blue, with a very 

 fine black anteciliary line, which towards the apex of the forewing in some 

 specimens becomes slightly diffused inwardly. Forewing with a patch of 

 irrorated white scales on the disc below the cell and between the median 

 nervules, very prominent in some specimens, obsolete in others (as in the 

 Sikkim specimen figured) . Hindwing with a similar patch, but placed be-
