NAG A HILL!S BUTTERILIES. 133 



Sub-family — Arhopalinee . 



Mahathala ameria, Hewitson, 



A single female taken at Nichuguard, Naga Hills, in March, and two more 

 at the end of April or beginning of May. 



Apporasa atkinsoni, Hewitson. 



A single female taken by my native collector at Sebong, Manipur, at the 

 beginning of June. 



I believe this species has not previously been recorded further north 

 than Tenasserim. 



Iraoxa rochana, Horsfield. 



Eight males of this beautiful species were obtained near Sebong, Manipur, 

 ill April, June, November and December. 



So far only recorded from Mergui within Indian limits. 



Iraota timoleon, Stoll. 



Males very common in the Manipur Valley. Females appear to be very 

 rare and none were taken in the Valley itself ; one was obtained at Sebong 

 in July, another female was obtained at Nichuguard, Naga Hills, in May ; 

 this female has onJy one tail and resembles the male in this respect ; the other 

 tail is not broken off. This species appears to be very variable ; typical 

 fimoleon being connected with typical mcecenas by intergradations. Mcscenas 

 forms were taken from January to July. Intermediate forms. May to July 

 and timoleon forms, June to October. 



ZiNASPA DISTORTA, De N. 



Not uncommon in Manipur during February and March ; rather scarce 

 during the wet-season. 



MoTA MASSYLA, Hewitson. 



Four males and numerous females taken at Sebong and on the Irang 

 River, Manipur, from January to July at low elevations. A single female 

 was also taken at Kirbari, Naga Hills, at about 6,000 feet in June. This 

 species amongst the § $ seems to vary greatly in colouring and size. My 

 smallest $ , taken in January, being only 0'9"' and my largest, taken in 

 June, 1-48". 



The males appear to be very rare. 



Arhopala camdeo, Moore. 

 Four males taken at Sebong, Manipur, in April. 



Arhopala apha suffusa, n. sub-sp. 



This form differs from typical a])ha in the DeNiceville collection in having 

 the underside suffused with lovely pink. Three males and a female taken at 

 Sebong in June. 



Arhopala silhetensis, Hewitson. 



Two males of this rare species were taken at the foot of the Naga Hills m 

 October and November and two males and two females at Sebong, Manipur,
