grey ; a small greyish- white discal patch. Hinclwing : costal area brown ; 

 the remainder of the wing bluish-grey ; veins slightly marked with darker 

 colour ; anal lobe yellow. Termen edged with black ; sex mark of modi- 

 fied scales gclden brown m some lights, dark grey in others. Underside : 

 exactly similar to that of S. virgo S as figured by De Niceville Butterflies, 

 India, Vol. Ill, Frontispiece Fig. 134. Cilia white. Female. Ufi^erside : 

 similar to the male but paler and discal patch on forewing much larger, as 

 large as in $ C. kina which it closely resembles. Underside: similar to the 

 male. 



Expanse : S V25" ; S 6 1-34", 



The underside of this species and of S. virgo is extraordinarily like C. kina. 



Two females taken at Jakama, Naga Hills, 6,000 feet, at the end of June, 

 and a male at the same place at the beginning of that month. 



Aerhenothkix penicillegka, De N. 



Four males and a female of the dry-season-form taken at Sebong and 

 on the Lengba River, Manipur, in March and April, and three wet-season 

 males in August. The dry-season males have the blue of a brighter shade 

 and rather more extensive than the wet-season-form. 



Oamena cotoides, n. sp (PI. IV., Fig. 38, S)- 



Very like C. cotys but difters as follows : — • 



Male. Upperside : blue colour brighter and more metallic extending in 

 interspaces land 2 of forewing right up to the termen ; area below the sex 

 mark on hindwing concolorous with the rest of the wing and not pale grey. 

 Underside : Forewing : dorsal tuft of hairs brown and not black ; sub- 

 marginal line on both wings not so continuous and straight but broken 

 up into lunules ; a raw of whitish lunules between the submarginal dark line 

 and the termen ; anal area of hindwing more densely irrorated with bluish- 

 grey scales. 



Expanse .- <S 1"6". 



A single male taken near Sebong, Manipur, in February. 



Mahteca bhoxea, Moore. 



A male and three females taken on the top of Kabru Peak, Manipur, 

 8,400 feet, in June and July and two males on Suroifui, 8,000-9,000 feet, 

 in June. 



I believe this species has not been previously recorded east of Sikkim. 



Ops melastigna, De N. 



A single female obtained at Sebong, Manipur, in April. 



Ops oeta, De N. 

 A single female obtained at Sebong in February. 



Tajukia istee, Hewitson. 



Thirteen males and two females of the dry-season-form taken at Imphal 

 in March and April and a male in June ; a male of the wet-season-form 

 taken in July and two more in August at the same place and four males and 

 three females at Imphal and Sebong in November. 



The males and females of this species are very like the female of C cleobis 

 on the upperside but can be readily distinguished on the underside by the 

 postdiscal band on forewing being placed closer to the termen. 



The male only differs from the female in having the blue on upper fore- 

 wing slightly restricted in interspace 3. The seasonal forms differ a good
